Ruby/Rails/Web related gedit/gtksourceview language definitions.¶ ↑

Part of RubyBuntuGedit

Features¶ ↑

Contains various language specs needed by Ruby/Rails/Web developers and also tries to maintain them.

• The Ruby language specification has been improved a lot. It uses 1.9.2 as reference implementation, recognizes many Ruby-specific language constructs (that can be highlighted differently) and implements many language details. To see all these changes, you need a style that supports (“uses”) the new specification, for example, these styles. See below for a changelog summary.

• ERB is not only usable with HTML, but also with JavaScript, YAML and XML…

• Gemfile.lock highlighting

Setup¶ ↑

You should also use up-to-date mime types.

as root¶ ↑

sudo cp *.lang /usr/share/gtksourceview-2.0/language-specs
# you can also delete the rhtml.lang (now done via html-erb)
sudo rm -f /usr/share/gtksourceview-2.0/language-specs/rhtml.lang
# and the ruby_on_rails.lang (except you want to have rails highlighting with an extra language..)
sudo rm -f /usr/share/gtksourceview-2.0/language-specs/ruby_on_rails.lang

as non-root¶ ↑

mkdir -p ~/.local/share/gtksourceview-2.0/language-specs
cp *.lang ~/.local/share/gtksourceview-2.0/language-specs
# you can also delete the rhtml.lang (now done via html-erb)
rm -f ~/.local/share/gtksourceview-2.0/language-specs/rhtml.lang
# and the ruby_on_rails.lang (except you want to have rails highlighting with an extra language..)
rm -f ~/.local/share/gtksourceview-2.0/language-specs/ruby_on_rails.lang

CHANGES¶ ↑

ruby.lang¶ ↑

• Uses 1.9 as reference implementation

• No Rails keywords, no extra language for Rails

• Refactored/updated keyword and builtin detection, highlight important constants and methods

• Improved function definition highlighting

• More logical style mappings (which also means: current styles are not fully ruby:compatible)

• Fix string interpolations

• Better support for advanced literals (e.g. ‘%x[]`, `%r<>`, …)

• Support Arrays & Hashes (inclusive 1.9 symbol syntax)

• Different heredoc matching

• Better symbol detection

• Small language details, like recognizing ‘__END__`

• Better unicode support

• See ‘git log` for full details

• Based on github.com/gmate/gmate/blob/master/lang-specs/ruby_on_rails.lang

ruby.lang - Advanced TODOs [not (easily) possible with gtksourceview]¶ ↑

• Improve heredocs (e.g. nested ones)

• Different colorizations for “end”s (e.g. def/begin, class/module, while/until, if/case, block), needs to detect modifier statements correctly :/

• Detect (multi-line) yard doc tag values

• Add escapable char for generic string delimiters

• Advanced regex highlighting + multi-line regexes

• ruby.lang-extras/known-bugs.rb

Languages to add/import/update¶ ↑

• SASS / SCSS / CSS

• COFFEE

• HAML

• SLIM

• YAML

• CUCUMBER

Meanwhile, you can, for example, use the ones found in gmate

MAYBE¶ ↑

• RDOC markup support (and cross-referencing in ruby)
