[RFC] Variable substitution in gtags.conf

[Shigio YAMAGUCHI]

Hi,

I'm thinking enabling variable substitution in gtags.conf.

It is simillar to sh(1).

'$name' is replaced with the value of variable 'name'.

Example1: Making meaning clear

[gtags.conf]

+-------------------------------------------

|default:tc=definitions:tc=main\

|definitions:\

| fgcolor=32:\

| bgcolor=44:

|main:\

| :GREP_COLOR='${fgcolor};${bgcolor};4':

$ gtags --conf=fgcolor

32

$ gtags --conf=bgcolor

44

$ gtags --conf=GREP_COLOR

'32;44;4'

Example2: Removal of repeats of same definition

[gtags.conf]

+-------------------------------------------

|default:library=/usr/local/lib/gtags/exuberant-ctags.la:\

|       :gtags_parser=C\:$library:\

|       :gtags_parser=C++\:$library:

$ gtags --conf=gtags_parser

C:/usr/local/lib/gtags/exuberant-ctags.la,C++:/usr/local/lib/gtags/exuberant-ctags.la

Is it useful?

Is there any problem?

Regards,

Shigio
