This patch is generated by the following commands (note: if you're running using OS X's sed, which accepts slightly different flags, you'll have to specify an actual backup suffix in -i, or use gsed from Homebrew): hg stat -c \ | cut -c 3- \ | tr '\n' '\0' \ | xargs -0 -P 8 gsed --follow-symlinks 's/\bnsCSSProperty\b/nsCSSPropertyID/g' -i'' Then: hg mv layout/style/nsCSSProperty.h layout/style/nsCSSPropertyID.h ... and finally, manually renaming nsCSSProperty in the include guard in nsCSSProperty.h. MozReview-Commit-ID: ZV6jyvmLfA --HG-- rename : layout/style/nsCSSProperty.h => layout/style/nsCSSPropertyID.h
