Meld: associate file extension with language syntax highlighting

  • 772

I use meld for graphical diff comparisons.

I would like to associate .tpp as a C++ source file for syntax highlighting purposes.

How do I do this?

    Meld uses the Gnome project's GtkSourceView component for syntax highlighting.

    In order to change the file associations, edit the following file:

    /usr/share/gtksourceview-3.0/language-specs/cpp.lang

    Edit the "globs" section under language/metadata/property and add ;*.tpp

    <property name="globs">*.cpp;*.cxx;*.cc;*.C;*.c++;*.tpp</property>
                                                 ^^^^^^

  2. You can create custom lang files in

    ~/.local/share/gtksourceview-3.0/language-specs/

    If the directory does not already exist, you can create it. Then copy the lang file you want to use as a template from

    /usr/share/gtksourceview-3.0/language-specs/
