@ -6,81 +6,6 @@ The Network Monitor (netmonitor) shows you all the network requests Firefox make
If you want to build the Network Monitor inside of the DevTools toolbox (Firefox Devtools Panels), follow the [simple Firefox build](https://developer.mozilla.org/docs/Mozilla/Developer_guide/Build_Instructions/Simple_Firefox_build) document in MDN. Start your compiled firefox and open the Firefox developer tool, you can see the Network Monitor inside.
If you would like to run the Network Monitor in the browser tab (experimental), you need following packages:
* [node](https://nodejs.org/) >= 6.9.x JavaScript runtime.
* [yarn](https://yarnpkg.com/docs/install) >= 0.21.x the package dependency management tool.
* [Firefox](https://www.mozilla.org/firefox/new/) any version or build from the source code.
## Quick Setup
Navigate to the `mozilla-central/devtools/client/netmonitor` folder with your terminal.
Note that this folder is available after `mozilla-central` was cloned in order to get a local copy of the repository. Then run the following commands:
```bash
# Install packages
yarn install
# Create a dev server instance for hosting netmonitor on browser
yarn start
# Run firefox
firefox http://localhost:8000 --start-debugger-server 6080
```
Then open `localhost:8000` in any browser to see all tabs in Firefox.
### More detailed setup
Instead of running command to open a new Firefox window like
```
firefox http://localhost:8000 --start-debugger-server 6080
```
If you have an opened Firefox browser, you can manually configure Firefox via type `about:config` in Firefox URL field, grant the warning to access preferences. And set these two preferences:
* disable `devtools.debugger.prompt-connection` to remove the connection prompt.
* enable `devtools.debugger.remote-enabled` to allow remote debugging a browser tab via the Mozilla remote debugging protocol (RDP)
Go to the Web Developer menu in Firefox and select [Developer Toolbar](https://developer.mozilla.org/docs/Tools/GCLI). Run the command
`listen 6080 mozilla-rdp`
The command will make Firefox act as a remote debugging server.
Run the command
`yarn start`
Then open `localhost:8000` in any browser to see all tabs in Firefox.
### How it works
The Network Monitor uses [webpack](https://webpack.js.org/) and several packages from [devtools-core](https://github.com/devtools-html/devtools-core) to run the Network Monitor as a normal web page. The Network Monitor uses [Mozilla remote debugging protocol](http://searchfox.org/mozilla-central/source/devtools/docs/backend/protocol.md) to fetch result and execute commands from Firefox browser.
![](https://hacks.mozilla.org/files/2017/06/image4.png)
Open `localhost:8000` in any browser to see the [launchpad](https://github.com/devtools-html/devtools-core/tree/master/packages/devtools-launchpad) interface. Devtools Launchpad will communicate with Firefox (the remote debugging server) and list all opened tabs from Firefox. Click one of the browser tab entry, now you can see the Network Monitor runs in a browser tab.
### Develop with related modules
When working on make the Network Monitor running in the browser tab, you may need to work on external modules. Besides the third party modules, here are modules required for the Network Monitor and is hosted under `devtools-html` (modules shared across Devtools):
* [devtools-config](https://github.com/devtools-html/devtools-core/blob/master/packages/devtools-config/#readme) config used in dev server
* [devtools-launchpad](https://github.com/devtools-html/devtools-core/blob/master/packages/devtools-launchpad/#readme) provide the dev server, landing page and the bootstrap functions to run devtools in the browser tab.
* [devtools-modules](https://github.com/devtools-html/devtools-core/blob/master/packages/devtools-modules/#readme) Devtools shared and shim modules.
* [devtools-source-editor](https://github.com/devtools-html/devtools-core/blob/master/packages/devtools-source-editor/#readme) Source Editor component.
* [devtools-reps](https://github.com/devtools-html/debugger.html/blob/master/packages/devtools-reps/#readme) remote object formatter for variables representation.
Do `yarn link` modules in related module directory, then do `yarn link [module-name]` after `yarn install` modules.
## Code Structure
Top level files are used to launch the Network Monitor inside of the DevTools toolbox or run in the browser tab (experimental). The Network Monitor source is mainly located in the `src/` folder, the same code base is used to run in both environments.
We prefer use web standard API instead of FIrefox specific API, to make the Network Monitor can be opened in any browser tab.
### Run inside of the DevTools toolbox

# The Design of GCLI
## Design Goals
GCLI should be:
- primarily for technical users.
- as fast as a traditional CLI. It should be possible to put your head down,
and look at the keyboard and use GCLI 'blind' at full speed without making
mistakes.
- principled about the way it encourages people to build commands. There is
benefit from unifying the underlying concepts.
- automatically helpful.
GCLI should not attempt to:
- convert existing GUI users to a CLI.
- use natural language input. The closest we should get to natural language is
thinking of commands as ```verb noun --adjective```.
- gain a touch based interface. Whilst it's possible (even probable) that touch
can provide further benefits to command line users, that can wait while we
catch up with 1985.
- slavishly follow the syntax of existing commands, predictability is more
important.
- be a programming language. Shell scripts are mini programming languages but
we have JavaScript sat just next door. It's better to integrate than compete.
## Design Challenges
What has changed since 1970 that might cause us to make changes to the design
of the command line?
### Connection limitations
Unix pre-dates the Internet and treats almost everything as a file. Since the
Internet it could be more useful to use URIs as ways to identify sources of data.
### Memory limitations
Modern computers have something like 6 orders of magnitude more memory than the
PDP-7 on which Unix was developed. Innovations like stdin/stdout and pipes are
ways to connect systems without long-term storage of the results. The ability
to store results for some time (potentially in more than one format)
significantly reduces the need for these concepts. We should make the results
of past commands addressable for re-use at a later time.
There are a number of possible policies for eviction of items from the history.
We should investigate options other than a simple stack.
### Multi-tasking limitations
Multi-tasking was a problem in 1970; the problem was getting a computer to do
many jobs on 1 core. Today the problem is getting a computer to do one job on
many cores. However we're stuck with this legacy in 2 ways. Firstly that the
default is to force everything to wait until the previous job is finished, but
more importantly that output from parallel jobs frequently collides
$ find / -ctime 5d -print &
$ find / -uid 0 -print &
// good luck working out what came from where
$ tail -f logfile.txt &
$ vi main.c
// have a nice time editing that file
GCLI should allow commands to be asynchronous and will provide UI elements to
inform the user of job completion. It will also keep asynchronous command
output contained within it's own display area.
### Output limitations
The PDP-7 had a teletype. There is something like 4 orders of magnitude more
information that can be displayed on a modern display than a 80x24 character
based console. We can use this flexibility to provide better help to the user
in entering their command.
The additional display richness can also allow interaction with result output.
Command output can include links to follow-up commands, and even ask for
additional input. (e.g. "your search returned zero results do you want to try
again with a different search string")
There is no reason why output must be static. For example, it could be
informative to see the results of an "ls" command alter given changes made by
subsequent commands. (It should be noted that there are times when historical
information is important too)
### Integration limitations
In 1970, command execution meant retrieving a program from storage, and running
it. This required minimal interaction between the command line processor and
the program being run, and was good for resource constrained systems.
This lack of interaction resulted in the processing of command line arguments
being done everywhere, when the task was better suited to command line.
We should provide metadata about the commands being run, to allow the command
line to process, interpret and provide help on the input.

# Developing GCLI
## About the code
The majority of the GCLI source is stored in the ``lib`` directory.
The ``docs`` directory contains documentation.
The ``scripts`` directory contains RequireJS that GCLI uses.
The ``build`` directory contains files used when creating builds.
The ``mozilla`` directory contains the mercurial patch queue of patches to apply
to mozilla-central.
The ``selenium-tests`` directory contains selenium web-page integration tests.
The source in the ``lib`` directory is split into 4 sections:
- ``lib/demo`` contains commands used in the demo page. It is not needed except
for demo purposes.
- ``lib/test`` contains a small test harness for testing GCLI.
- ``lib/gclitest`` contains tests that run in the test harness
- ``lib/gcli`` contains the actual meat
GCLI is split into a UI portion and a Model/Controller portion.
## The GCLI Model
The heart of GCLI is a ``Requisition``, which is an AST for the input. A
``Requisition`` is a command that we'd like to execute, and we're filling out
all the inputs required to execute the command.
A ``Requisition`` has a ``Command`` that is to be executed. Each Command has a
number of ``Parameter``s, each of which has a name and a type as detailed
above.
As you type, your input is split into ``Argument``s, which are then assigned to
``Parameter``s using ``Assignment``s. Each ``Assignment`` has a ``Conversion``
which stores the input argument along with the value that is was converted into
according to the type of the parameter.
There are special assignments called ``CommandAssignment`` which the
``Requisition`` uses to link to the command to execute, and
``UnassignedAssignment``used to store arguments that do not have a parameter
to be assigned to.
## The GCLI UI
There are several components of the GCLI UI. Each can have a script portion,
some template HTML and a CSS file. The template HTML is processed by
``domtemplate`` before use.
DomTemplate is fully documented in [it's own repository]
(https://github.com/joewalker/domtemplate).
The components are:
- ``Inputter`` controls the input field, processing special keyboard events and
making sure that it stays in sync with the Requisition.
- ``Completer`` updates a div that is located behind the input field and used
to display completion advice and hint highlights. It is stored in
completer.js.
- ``Display`` is responsible for containing the popup hints that are displayed
above the command line. Typically Display contains a Hinter and a RequestsView
although these are not both required. Display itself is optional, and isn't
planned for use in the first release of GCLI in Firefox.
- ``Hinter`` Is used to display input hints. It shows either a Menu or an
ArgFetch component depending on the state of the Requisition
- ``Menu`` is used initially to select the command to be executed. It can act
somewhat like the Start menu on windows.
- ``ArgFetch`` Once the command to be executed has been selected, ArgFetch
shows a 'dialog' allowing the user to enter the parameters to the selected
command.
- ``RequestsView`` Contains a set of ``RequestView`` components, each of which
displays a command that has been invoked. RequestsView is a poor name, and
should better be called ReportView
ArgFetch displays a number of Fields. There are fields for most of the Types
discussed earlier. See 'Writing Fields' above for more information.
## Testing
GCLI contains 2 test suites:
- JS level testing is run with the ``test`` command. The tests are located in
``lib/gclitest`` and they use the test runner in ``lib/test``. This is fairly
comprehensive, however it does not do UI level testing.
If writing a new test it needs to be registered in ``lib/gclitest/index``.
For an example of how to write tests, see ``lib/gclitest/testSplit.js``.
The test functions are implemented in ``lib/test/assert``.
- Browser integration tests are included in ``browser_webconsole_gcli_*.js``,
in ``toolkit/components/console/hudservice/tests/browser``. These are
run with the rest of the Mozilla test suite.
## Coding Conventions
The coding conventions for the GCLI project come from the Bespin/Skywriter and
Ace projects. They are roughly [Crockford]
(http://javascript.crockford.com/code.html) with a few exceptions and
additions:
* ``var`` does not need to be at the top of each function, we'd like to move
to ``let`` when it's generally available, and ``let`` doesn't have the same
semantic twists as ``var``.
* Strings are generally enclosed in single quotes.
* ``eval`` is to be avoided, but we don't declare it evil.
The [Google JavaScript conventions]
(https://google-styleguide.googlecode.com/svn/trunk/javascriptguide.xml) are
more detailed, we tend to deviate in:
* Custom exceptions: We generally just use ``throw new Error('message');``
* Multi-level prototype hierarchies: Allowed; we don't have ``goog.inherits()``
* ``else`` begins on a line by itself:
if (thing) {
doThis();
}
else {
doThat();
}
## Startup
Internally GCLI modules have ``startup()``/``shutdown()`` functions which are
called on module init from the top level ``index.js`` of that 'package'.
In order to initialize a package all that is needed is to require the package
index (e.g. ``require('package/index')``).
The ``shutdown()`` function was useful when GCLI was used in Bespin as part of
dynamic registration/de-registration. It is not known if this feature will be
useful in the future. So it has not been entirely removed, it may be at some
future date.
## Running the Unit Tests
Start the GCLI static server:
cd path/to/gcli
node gcli.js
Now point your browser to http://localhost:9999/localtest.html. When the page
loads the tests will be automatically run outputting to the console, or you can
enter the ``test`` command to run the unit tests.
## Contributing Code
Please could you do the following to help minimize the amount of rework that we
do:
1. Check the unit tests run correctly (see **Running the Unit Tests** above)
2. Check the code follows the style guide. At a minimum it should look like the
code around it. For more detailed notes, see **Coding Conventions** above
3. Help me review your work by using good commit comments. Which means 2 things
* Well formatted messages, i.e. 50 char summary including bug tag, followed
by a blank line followed by a more in-depth message wrapped to 72 chars
per line. This is basically the format used by the Linux Kernel. See the
[commit log](https://github.com/joewalker/gcli/commits/master) for
examples. The be extra helpful, please use the "shortdesc-BUGNUM: " if
possible which also helps in reviews.
* Commit your changes as a story. Make it easy for me to understand the
changes that you've made.
4. Sign your work. To improve tracking of who did what, we follow the sign-off
procedure used in the Linux Kernel.
The sign-off is a simple line at the end of the explanation for the
patch, which certifies that you wrote it or otherwise have the right to
pass it on as an open-source patch. The rules are pretty simple: if you
can certify the below:
Developer's Certificate of Origin 1.1
By making a contribution to this project, I certify that:
(a) The contribution was created in whole or in part by me and I
have the right to submit it under the open source license
indicated in the file; or
(b) The contribution is based upon previous work that, to the best
of my knowledge, is covered under an appropriate open source
license and I have the right under that license to submit that
work with modifications, whether created in whole or in part
by me, under the same open source license (unless I am
permitted to submit under a different license), as indicated
in the file; or
(c) The contribution was provided directly to me by some other
person who certified (a), (b) or (c) and I have not modified
it.
(d) I understand and agree that this project and the contribution
are public and that a record of the contribution (including all
personal information I submit with it, including my sign-off) is
maintained indefinitely and may be redistributed consistent with
this project or the open source license(s) involved.
then you just add a line saying
Signed-off-by: Random J Developer <random@developer.example.org>
using your real name (sorry, no pseudonyms or anonymous contributions.)
Thanks for wanting to contribute code.

# About GCLI
## GCLI is a Graphical Command Line Interpreter.
GCLI is a command line for modern computers. When command lines were invented,
computers were resource-limited, disconnected systems with slow multi-tasking
and poor displays. The design of the Unix CLI made sense in 1970, but over 40
years on, considering the pace of change, there are many improvements we can
make.
CLIs generally suffer from poor discoverability; It's hard when faced with a
blank command line to work out what to do. As a result the majority of programs
today use purely graphical user interfaces, however in doing so, they lose some
of the benefits of CLIs. CLIs are still used because generally, in the hands of
a skilled user they are faster, and have a wider range of available options.
GCLI attempts to get the best of the GUI world and the CLI world to produce
something that is both easy to use and learn as well as fast and powerful.
GCLI has a type system to help ensure that users are inputting valid commands
and to enable us to provide sensible context sensitive help. GCLI provides
integration with JavaScript rather than being an alternative (like CoffeeScript).
## History
GCLI was born as part of the
[Bespin](http://ajaxian.com/archives/canvas-for-a-text-editor) project and was
[discussed at the time](http://j.mp/bespin-cli). The command line component
survived the rename of Bepsin to Skywriter and the merger with Ace, got a name
of it's own (Cockpit) which didn't last long before the project was named GCLI.
It is now being used in the Firefox's web console where it doesn't have a
separate identity but it's still called GCLI outside of Firefox. It is also
used in [Eclipse Orion](http://www.eclipse.org/orion/).
## Environments
GCLI is designed to work in a number of environments:
1. As a component of Firefox developer tools.
2. As an adjunct to Orion/Ace and other online editors.
3. As a plugin to any web-page wishing to provide its own set of commands.
4. As part of a standalone web browser extension with it's own set of commands.

## Accessibility
GCLI uses ARIA roles to guide a screen-reader as to the important sections to
voice. We welcome [feedback on how these roles are implemented](https://bugzilla.mozilla.org/enter_bug.cgi?product=Firefox&component=Developer+Tools:+Graphic+Commandline+and+Toolbar&rep_platform=All&op_sys=All&short_desc=GCLI).
The command line uses TAB as a method of completing current input, this
prevents use of TAB for keyboard navigation. Instead of using TAB to move to
the next field you can use F6. In addition to F6, ALT+TAB, CTRL+TAB, META+TAB
make an attempt to move the focus on. How well this works depends on your
OS/browser combination.
## Embedding GCLI
There are 3 basic steps in using GCLI in your system.
1. Import a GCLI JavaScript file.
For serious use of GCLI you are likely to be creating a custom build (see
below) however if you just want to have a quick play, you can use
``gcli-uncompressed.js`` from [the gh-pages branch of GCLI]
(https://github.com/mozilla/gcli/tree/gh-pages)
Just place the following wherever you place your script files.
<script src="path/to/gcli-uncompressed.js" type="text/javascript"></script>
2. Having imported GCLI, we need to tell it where to display. The simplest
method is to include an elements with the id of ``gcli-input`` and
``gcli-display``.
<input id="gcli-input" type="text"/>
<div id="gcli-display"></div>
3. Tell GCLI what commands to make available. See the sections on Writing
Commands, Writing Types and Writing Fields for more information.
GCLI uses the CommonJS AMD format for it's files, so a 'require' statement
is needed to get started.
require([ 'gcli/index' ], function(gcli) {
gcli.add(...); // Register custom commands/types/etc
gcli.createTerminal(); // Create a user interface
});
The createTerminal() function takes an ``options`` objects which allows
customization. At the current time the documentation of these object is left
to the source.
## Backwards Compatibility
The goals of the GCLI project are:
- Aim for very good backwards compatibility with code required from an
'index' module. This means we will not break code without a cycle of
deprecation warnings.
There are currently 3 'index' modules:
- gcli/index (all you need to get started with GCLI)
- demo/index (a number of demo commands)
- gclitest/index (GCLI test suite)
Code from these modules uses the module pattern to prevent access to internal
functions, so in essence, if you can get to it from an index module, you
should be ok.
- We try to avoid needless change to other modules, however we don't make any
promises, and don't provide a deprecation cycle.
Code from other modules uses classes rather than modules, so member variables
are exposed. Many classes mark private members using the `_underscorePrefix`
pattern. Particular care should be taken if access is needed to a private
member.
## Creating Custom Builds
GCLI uses [DryIce](https://github.com/mozilla/dryice) to create custom builds.
If dryice is installed (``npm install .``) then you can create a built
version of GCLI simply using ``node gcli.js standard``. DryIce supplies a custom
module loader to replace RequireJS for built applications.
The build will be output to the ``built`` directory. The directory will be
created if it doesn't exist.

# Running Tests
GCLI has a test suite that can be run in a number of different environments.
Some of the tests don't work in all environments. These should be automatically
skipped when not applicable.
## Web
Running a limited set of test from the web is the easiest. Simply load
'localtest.html' and the unit tests should be run automatically, with results
displayed on the console. Tests can be re-run using the 'test' command.
It also creates a function 'testCommands()' to be run at a JS prompt, which
enables the test commands for debugging purposes.
## Firefox
GCLI's test suite integrates with Mochitest and runs automatically on each test
run. Dryice packages the tests to format them for the Firefox build system.
For more information about running Mochitest on Firefox (including GCLI) see
[the MDN, Mochitest docs](https://developer.mozilla.org/en/Mochitest)
# Node
Running the test suite under node can be done as follows:
$ node gcli.js test
Or, using the `test` command:
$ node gcli.js
Serving GCLI to http://localhost:9999/
This is also a limited GCLI prompt.
Type 'help' for a list of commands, CTRL+C twice to exit:
: test
testCli: Pass (funcs=9, checks=208)
testCompletion: Pass (funcs=1, checks=139)
testExec: Pass (funcs=1, checks=133)
testHistory: Pass (funcs=3, checks=13)
....
Summary: Pass (951 checks)
# Travis CI
GCLI check-ins are automatically tested by [Travis CI](https://travis-ci.org/joewalker/gcli).
# Test Case Generation
GCLI can generate test cases automagically. Load ```localtest.html```, type a
command to be tested into GCLI, and the press F2. GCLI will output to the
console a template test case for the entered command.

# Writing Commands
## Basics
GCLI has opinions about how commands should be written, and it encourages you
to do The Right Thing. The opinions are based on helping users convert their
intentions to commands and commands to what's actually going to happen.
- Related commands should be sub-commands of a parent command. One of the goals
of GCLI is to support a large number of commands without things becoming
confusing, this will require some sort of namespacing or there will be
many people wanting to implement the ``add`` command. This style of
writing commands has become common place in Unix as the number of commands
has gone up.
The ```context``` command allows users to focus on a parent command, promoting
its sub-commands above others.
- Each command should do exactly and only one thing. An example of a Unix
command that breaks this principle is the ``tar`` command
$ tar -zcf foo.tar.gz .
$ tar -zxf foo.tar.gz .
These 2 commands do exactly opposite things. Many a file has died as a result
of a x/c typo. In GCLI this would be better expressed:
$ tar create foo.tar.gz -z .
$ tar extract foo.tar.gz -z .
There may be commands (like tar) which have enough history behind them
that we shouldn't force everyone to re-learn a new syntax. The can be achieved
by having a single string parameter and parsing the input in the command)
- Avoid errors. We try to avoid the user having to start again with a command
due to some problem. The majority of problems are simple typos which we can
catch using command metadata, but there are 2 things command authors can do
to prevent breakage.
- Where possible avoid the need to validate command line parameters in the
exec function. This can be done by good parameter design (see 'do exactly
and only one thing' above)
- If there is an obvious fix for an unpredictable problem, offer the
solution in the command output. So rather than use request.error (see
Request Object below) output some HTML which contains a link to a fixed
command line.
Currently these concepts are not enforced at a code level, but they could be in
the future.
## How commands work
This is how to create a basic ``greet`` command:
gcli.addItems([{
name: 'greet',
description: 'Show a greeting',
params: [
{
name: 'name',
type: 'string',
description: 'The name to greet'
}
],
returnType: 'string',
exec: function(args, context) {
return 'Hello, ' + args.name;
}
}]);
This command is used as follows:
: greet Joe
Hello, Joe
Some terminology that isn't always obvious: a function has 'parameters', and
when you call a function, you pass 'arguments' to it.
## Internationalization (i18n)
There are several ways that GCLI commands can be localized. The best method
depends on what context you are writing your command for.
### Firefox Embedding
GCLI supports Mozilla style localization. To add a command that will only ever
be used embedded in Firefox, this is the way to go. Your strings should be
stored in ``toolkit/locales/en-US/chrome/global/devtools/gclicommands.properties``,
And you should access them using ``let l10n = require("gcli/l10n")`` and then
``l10n.lookup(...)`` or ``l10n.lookupFormat()``
For examples of existing commands, take a look in
``devtools/client/webconsole/GcliCommands.jsm``, which contains most of the
current GCLI commands. If you will be adding a number of new commands, then
consider starting a new JSM.
Your command will then look something like this:
gcli.addItems([{
name: 'greet',
description: gcli.lookup("greetDesc")
...
}]);
### Web Commands
There are 2 ways to provide translated strings for web use. The first is to
supply the translated strings in the description:
gcli.addItems([{
name: 'greet',
description: {
'root': 'Show a greeting',
'fr-fr': 'Afficher un message d'accueil',
'de-de': 'Zeige einen Gruß',
'gk-gk': 'Εμφάνιση ένα χαιρετισμό',
...
}
...
}]);
Each description should contain at least a 'root' entry which is the
default if no better match is found. This method has the benefit of being
compact and simple, however it has the significant drawback of being wasteful
of memory and bandwidth to transmit and store a significant number of strings,
the majority of which will never be used.
More efficient is to supply a lookup key and ask GCLI to lookup the key from an
appropriate localized strings file:
gcli.addItems([{
name: 'greet',
description: { 'key': 'demoGreetingDesc' }
...
}]);
For web usage, the central store of localized strings is
``lib/gcli/nls/strings.js``. Other string files can be added using the
``l10n.registerStringsSource(...)`` function.
This method can be used both in Firefox and on the Web (see the help command
for an example). However this method has the drawback that it will not work
with DryIce built files until we fix bug 683844.
## Default argument values
The ``greet`` command requires the entry of the ``name`` parameter. This
parameter can be made optional with the addition of a ``defaultValue`` to the
parameter:
gcli.addItems([{
name: 'greet',
description: 'Show a message to someone',
params: [
{
name: 'name',
type: 'string',
description: 'The name to greet',
defaultValue: 'World!'
}
],
returnType: 'string',
exec: function(args, context) {
return "Hello, " + args.name;
}
}]);
Now we can also use the ``greet`` command as follows:
: greet
Hello, World!
## Positional vs. named arguments
Arguments can be entered either positionally or as named arguments. Generally
users will prefer to type the positional version, however the named alternative
can be more self documenting.
For example, we can also invoke the greet command as follows:
: greet --name Joe
Hello, Joe
## Short argument names
GCLI allows you to specify a 'short' character for any parameter:
gcli.addItems([{
name: 'greet',
params: [
{
name: 'name',
short: 'n',
type: 'string',
...
}
],
...
}]);
This is used as follows:
: greet -n Fred
Hello, Fred
Currently GCLI does not allow short parameter merging (i.e. ```ls -la```)
however this is planned.
## Parameter types
Initially the available types are:
- string
- boolean
- number
- selection
- delegate
- date
- array
- file
- node
- nodelist
- resource
- command
- setting
This list can be extended. See [Writing Types](writing-types.md) on types for
more information.
The following examples assume the following definition of the ```greet```
command:
gcli.addItems([{
name: 'greet',
params: [
{ name: 'name', type: 'string' },
{ name: 'repeat', type: 'number' }
],
...
}]);
Parameters can be specified either with named arguments:
: greet --name Joe --repeat 2
And sometimes positionally:
: greet Joe 2
Parameters can be specified positionally if they are considered 'important'.
Unimportant parameters must be specified with a named argument.
Named arguments can be specified anywhere on the command line (after the
command itself) however positional arguments must be in order. So
these examples are the same:
: greet --name Joe --repeat 2
: greet --repeat 2 --name Joe
However (obviously) these are not the same:
: greet Joe 2
: greet 2 Joe
(The second would be an error because 'Joe' is not a number).
Named arguments are assigned first, then the remaining arguments are assigned
to the remaining parameters. So the following is valid and unambiguous:
: greet 2 --name Joe
Positional parameters quickly become unwieldy with long parameter lists so we
recommend only having 2 or 3 important parameters. GCLI provides hints for
important parameters more obviously than unimportant ones.
Parameters are 'important' if they are not in a parameter group. The easiest way
to achieve this is to use the ```option: true``` property.
For example, using:
gcli.addItems([{
name: 'greet',
params: [
{ name: 'name', type: 'string' },
{ name: 'repeat', type: 'number', option: true, defaultValue: 1 }
],
...
}]);
Would mean that this is an error
: greet Joe 2
You would instead need to do the following:
: greet Joe --repeat 2
For more on parameter groups, see below.
In addition to being 'important' and 'unimportant' parameters can also be
optional. If is possible to be important and optional, but it is not possible
to be unimportant and non-optional.
Parameters are optional if they either:
- Have a ```defaultValue``` property
- Are of ```type=boolean``` (boolean arguments automatically default to being false)
There is currently no way to make parameters mutually exclusive.
## Selection types
Parameters can have a type of ``selection``. For example:
gcli.addItems([{
name: 'greet',
params: [
{ name: 'name', ... },
{
name: 'lang',
description: 'In which language should we greet',
type: { name: 'selection', data: [ 'en', 'fr', 'de', 'es', 'gk' ] },
defaultValue: 'en'
}
],
...
}]);
GCLI will enforce that the value of ``arg.lang`` was one of the values
specified. Alternatively ``data`` can be a function which returns an array of
strings.
The ``data`` property is useful when the underlying type is a string but it
doesn't work when the underlying type is something else. For this use the
``lookup`` property as follows:
type: {
name: 'selection',
lookup: {
'en': Locale.EN,
'fr': Locale.FR,
...
}
},
Similarly, ``lookup`` can be a function returning the data of this type.
## Number types
Number types are mostly self explanatory, they have one special property which
is the ability to specify upper and lower bounds for the number:
gcli.addItems([{
name: 'volume',
params: [
{
name: 'vol',
description: 'How loud should we go',
type: { name: 'number', min: 0, max: 11 }
}
],
...
}]);
You can also specify a ``step`` property which specifies by what amount we
should increment and decrement the values. The ``min``, ``max``, and ``step``
properties are used by the command line when up and down are pressed and in
the input type of a dialog generated from this command.
## Delegate types
Delegate types are needed when the type of some parameter depends on the type
of another parameter. For example:
: set height 100
: set name "Joe Walker"
We can achieve this as follows:
gcli.addItems([{
name: 'set',
params: [
{
name: 'setting',
type: { name: 'selection', values: [ 'height', 'name' ] }
},
{
name: 'value',
type: {
name: 'delegate',
delegateType: function() { ... }
}
}
],
...
}]);
Several details are left out of this example, like how the delegateType()
function knows what the current setting is. See the ``pref`` command for an
example.
## Array types
Parameters can have a type of ``array``. For example:
gcli.addItems([{
name: 'greet',
params: [
{
name: 'names',
type: { name: 'array', subtype: 'string' },
description: 'The names to greet',
defaultValue: [ 'World!' ]
}
],
...
exec: function(args, context) {
return "Hello, " + args.names.join(', ') + '.';
}
}]);
This would be used as follows:
: greet Fred Jim Shiela
Hello, Fred, Jim, Shiela.
Or using named arguments:
: greet --names Fred --names Jim --names Shiela
Hello, Fred, Jim, Shiela.
There can only be one ungrouped parameter with an array type, and it must be
at the end of the list of parameters (i.e. just before any parameter groups).
This avoids confusion as to which parameter an argument should be assigned.
## Sub-commands
It is common for commands to be groups into those with similar functionality.
Examples include virtually all VCS commands, ``apt-get``, etc. There are many
examples of commands that should be structured as in a sub-command style -
``tar`` being the obvious example, but others include ``crontab``.
Groups of commands are specified with the top level command not having an
exec function:
gcli.addItems([
{
name: 'tar',
description: 'Commands to manipulate archives',
},
{
name: 'tar create',
description: 'Create a new archive',
exec: function(args, context) { ... },
...
},
{
name: 'tar extract',
description: 'Extract from an archive',
exec: function(args, context) { ... },
...
}
]);
## Parameter groups
Parameters can be grouped into sections.
There are 3 ways to assign a parameter to a group.
The simplest uses ```option: true``` to put a parameter into the default
'Options' group:
gcli.addItems([{
name: 'greet',
params: [
{ name: 'repeat', type: 'number', option: true }
],
...
}]);
The ```option``` property can also take a string to use an alternative parameter
group:
gcli.addItems([{
name: 'greet',
params: [
{ name: 'repeat', type: 'number', option: 'Advanced' }
],
...
}]);
An example of how this can be useful is 'git' which categorizes parameters into
'porcelain' and 'plumbing'.
Finally, parameters can be grouped together as follows:
gcli.addItems([{
name: 'greet',
params: [
{ name: 'name', type: 'string', description: 'The name to greet' },
{
group: 'Advanced Options',
params: [
{ name: 'repeat', type: 'number', defaultValue: 1 },
{ name: 'debug', type: 'boolean' }
]
}
],
...
}]);
This could be used as follows:
: greet Joe --repeat 2 --debug
About to send greeting
Hello, Joe
Hello, Joe
Done!
Parameter groups must come after non-grouped parameters because non-grouped
parameters can be assigned positionally, so their index is important. We don't
want 'holes' in the order caused by parameter groups.
## Command metadata
Each command should have the following properties:
- A string ``name``.
- A short ``description`` string. Generally no more than 20 characters without
a terminating period/fullstop.
- A function to ``exec``ute. (Optional for the parent containing sub-commands)
See below for more details.
And optionally the following extra properties:
- A declaration of the accepted ``params``.
- A ``hidden`` property to stop the command showing up in requests for help.
- A ``context`` property which defines the scope of the function that we're
calling. Rather than simply call ``exec()``, we do ``exec.call(context)``.
- A ``manual`` property which allows a fuller description of the purpose of the
command.
- A ``returnType`` specifying how we should handle the value returned from the
exec function.
The ``params`` property is an array of objects, one for each parameter. Each
parameter object should have the following 3 properties:
- A string ``name``.
- A short string ``description`` as for the command.
- A ``type`` which refers to an existing Type (see Writing Types).
Optionally each parameter can have these properties:
- A ``defaultValue`` (which should be in the type specified in ``type``).
The defaultValue will be used when there is no argument supplied for this
parameter on the command line.
If the parameter has a ``defaultValue``, other than ``undefined`` then the
parameter is optional, and if unspecified on the command line, the matching
argument will have this value when the function is called.
If ``defaultValue`` is missing, or if it is set to ``undefined``, then the
system will ensure that a value is provided before anything is executed.
There are 2 special cases:
- If the type is ``selection``, then defaultValue must not be undefined.
The defaultValue must either be ``null`` (meaning that a value must be
supplied by the user) or one of the selection values.
- If the type is ``boolean``, then ``defaultValue:false`` is implied and
can't be changed. Boolean toggles are assumed to be off by default, and
should be named to match.
- A ``manual`` property for parameters is exactly analogous to the ``manual``
property for commands - descriptive text that is longer than than 20
characters.
## The Command Function (exec)
The parameters to the exec function are designed to be useful when you have a
large number of parameters, and to give direct access to the environment (if
used).
gcli.addItems([{
name: 'echo',
description: 'The message to display.',
params: [
{
name: 'message',
type: 'string',
description: 'The message to display.'
}
],
returnType: 'string',
exec: function(args, context) {
return args.message;
}
}]);
The ``args`` object contains the values specified on the params section and
provided on the command line. In this example it would contain the message for
display as ``args.message``.
The ``context`` object has the following signature:
{
environment: ..., // environment object passed to createTerminal()
exec: ..., // function to execute a command
update: ..., // function to alter the text of the input area
createView: ..., // function to help creating rich output
defer: ..., // function to create a deferred promise
}
The ``environment`` object is opaque to GCLI. It can be used for providing
arbitrary data to your commands about their environment. It is most useful
when more than one command line exists on a page with similar commands in both
which should act in their own ways.
An example use for ``environment`` would be a page with several tabs, each
containing an editor with a command line. Commands executed in those editors
should apply to the relevant editor.
The ``environment`` object is passed to GCLI at startup (probably in the
``createTerminal()`` function).
The ``document`` object is also passed to GCLI at startup. In some environments
(e.g. embedded in Firefox) there is no global ``document``. This object
provides a way to create DOM nodes.
``defer()`` allows commands to execute asynchronously.
## Returning data
The command meta-data specifies the type of data returned by the command using
the ``returnValue`` setting.
``returnValue`` processing is currently functioning, but incomplete, and being
tracked in [Bug 657595](http://bugzil.la/657595). Currently you should specify
a ``returnType`` of ``string`` or ``html``. If using HTML, you can return
either an HTML string or a DOM node.
In the future, JSON will be strongly encouraged as the return type, with some
formatting functions to convert the JSON to HTML.
Asynchronous output is achieved using a promise created from the ``context``
parameter: ``context.defer()``.
Some examples of this is practice:
{ returnType: "string" }
...
return "example";
GCLI interprets the output as a plain string. It will be escaped before display
and available as input to other commands as a plain string.
{ returnType: "html" }
...
return "<p>Hello</p>";
GCLI will interpret this as HTML, and parse it for display.
{ returnType: "dom" }
...
return util.createElement(context.document, 'div');
``util.createElement`` is a utility to ensure use of the XHTML namespace in XUL
and other XML documents. In an HTML document it's functionally equivalent to
``context.document.createElement('div')``. If your command is likely to be used
in Firefox or another XML environment, you should use it. You can import it
with ``var util = require('util/util');``.
GCLI will use the returned HTML element as returned. See notes on ``context``
above.
{ returnType: "number" }
...
return 42;
GCLI will display the element in a similar way to a string, but it the value
will be available to future commands as a number.
{ returnType: "date" }
...
return new Date();
{ returnType: "file" }
...
return new File();
Both these examples return data as a given type, for which a converter will
be required before the value can be displayed. The type system is likely to
change before this is finalized. Please contact the author for more
information.
{ returnType: "string" }
...
var deferred = context.defer();
setTimeout(function() {
deferred.resolve("hello");
}, 500);
return deferred.promise;
Errors can be signaled by throwing an exception. GCLI will display the message
property (or the toString() value if there is no message property). (However
see *3 principles for writing commands* above for ways to avoid doing this).
## Specifying Types
Types are generally specified by a simple string, e.g. ``'string'``. For most
types this is enough detail. There are a number of exceptions:
* Array types. We declare a parameter to be an array of things using ``[]``,
for example: ``number[]``.
* Selection types. There are 3 ways to specify the options in a selection:
* Using a lookup map
type: {
name: 'selection',
lookup: { one:1, two:2, three:3 }
}
(The boolean type is effectively just a selection that uses
``lookup:{ 'true': true, 'false': false }``)
* Using given strings
type: {
name: 'selection',
data: [ 'left', 'center', 'right' ]
}
* Using named objects, (objects with a ``name`` property)
type: {
name: 'selection',
data: [
{ name: 'Google', url: 'http://www.google.com/' },
{ name: 'Microsoft', url: 'http://www.microsoft.com/' },
{ name: 'Yahoo', url: 'http://www.yahoo.com/' }
]
}
* Delegate type. It is generally best to inherit from Delegate in order to
provide a customization of this type. See settingValue for an example.
See below for more information.

# Writing Tests
There are several sources of GCLI tests and several environments in which they
are run.
The majority of GCLI tests are stored in
[this repository](https://github.com/joewalker/gcli/) in files named like
```./lib/gclitest/test*.js```. These tests run in Firefox, Chrome, Opera,
and NodeJS/JsDom
See [Running Tests](running-tests.md) for further details.
GCLI comes with a generic unit test harness (in ```./lib/test/```) and a
set of helpers for creating GCLI tests (in ```./lib/gclitest/helpers.js```).
# GCLI tests in Firefox
The build process converts the GCLI tests to run under Mochitest inside the
Firefox unit tests. It also adds some

# Writing Types
Commands are a fundamental building block because they are what the users
directly interacts with, however they are built on ``Type``s. There are a
number of built in types:
* string. This is a JavaScript string
* number. A JavaScript number
* boolean. A JavaScript boolean
* selection. This is an selection from a number of alternatives
* delegate. This type could change depending on other factors, but is well
defined when one of the conversion routines is called.
There are a number of additional types defined by Pilot and GCLI as
extensions to the ``selection`` and ``delegate`` types
* setting. One of the defined settings
* settingValue. A value that can be applied to an associated setting.
* command. One of the defined commands
Most of our types are 'static' e.g. there is only one type of 'string', however
some types like 'selection' and 'delegate' are customizable.
All types must inherit from Type and have the following methods:
/**
* Convert the given <tt>value</tt> to a string representation.
* Where possible, there should be round-tripping between values and their
* string representations.
*/
stringify: function(value) { return 'string version of value'; },
/**
* Convert the given <tt>str</tt> to an instance of this type.
* Where possible, there should be round-tripping between values and their
* string representations.
* @return Conversion
*/
parse: function(str) { return new Conversion(...); },
/**
* The plug-in system, and other things need to know what this type is
* called. The name alone is not enough to fully specify a type. Types like
* 'selection' and 'delegate' need extra data, however this function returns
* only the name, not the extra data.
* <p>In old bespin, equality was based on the name. This may turn out to be
* important in Ace too.
*/
name: 'example',
In addition, defining the following function can be helpful, although Type
contains default implementations:
* nudge(value, by)
Type, Conversion and Status are all declared by commands.js.
The values produced by the parse function can be of any type, but if you are
producing your own, you are strongly encouraged to include properties called
``name`` and ``description`` where it makes sense. There are a number of
places in GCLI where the UI will be able to provide better help to users if
your values include these properties.
# Writing Fields
Fields are visual representations of types. For simple types like string it is
enough to use ``<input type=...>``, however more complex types we may wish to
provide a custom widget to allow the user to enter values of the given type.
This is an example of a very simple new password field type:
function PasswordField(doc) {
this.doc = doc;
}
PasswordField.prototype = Object.create(Field.prototype);
PasswordField.prototype.createElement = function(assignment) {
this.assignment = assignment;
this.input = dom.createElement(this.doc, 'input');
this.input.type = 'password';
this.input.value = assignment.arg ? assignment.arg.text : '';
this.onKeyup = function() {
this.assignment.setValue(this.input.value);
}.bind(this);
this.input.addEventListener('keyup', this.onKeyup, false);
this.onChange = function() {
this.input.value = this.assignment.arg.text;
};
this.assignment.onAssignmentChange.add(this.onChange, this);
return this.input;
};
PasswordField.prototype.destroy = function() {
this.input.removeEventListener('keyup', this.onKeyup, false);
this.assignment.onAssignmentChange.remove(this.onChange, this);
};
PasswordField.claim = function(type) {
return type.name === 'password' ? Field.claim.MATCH : Field.claim.NO_MATCH;
};

* focus, and invisible at other times, without hiding and showing the hint
* element even briefly as the focus changes between them.
* It does this simply by postponing the hide events by 250ms to see if
