This file describes the XML format used for syntax highlight
|
|
descriptions for the GtkSourceView 1.x library.
|
|
|
|
.lang files are XML files which describe how to highlight syntax;
|
|
this RNG is used for validation purposes.
|
|
|
|
.lang files should be located in $PREFIX/gtksourceview-1.0/language-specs/,
|
|
or in ~./gnome2/gtksourceview-1.0/language-specs/
|
|
|
|
To check if a .lang file is valid, run
|
|
|
|
$ xmllint FILENAME - -relaxng language.rng
|
|
|
|
If you create a new .lang file or modify an existing one, please note
|
|
that it will be (re)loaded by the application only after it is
|
|
restarted.

|
|
- 'false', FALSE' and '0' all meaning false
|
|
|
|
It is encouraged to use 'TRUE' and 'FALSE' instead of the alternatives.
