Re: function calls are not referenced for Bash scripts

[Yoshitaro Makise]

Hello,

For shell scripts, pygments plugin does not support function
references. It just support variables for references.

----------------------
$ cat test.sh
#!/bin/bash

foo() {
    bar
}

bar() {
    echo $message
}

message=hello
foo

$ gtags
$ gtags -d GRTAGS
 __.COMPACT __.COMPACT
 __.COMPLINE __.COMPLINE
 __.COMPNAME __.COMPNAME
 __.VERSION __.VERSION 6
echo 1 @n 8
message 1 @n 8,3

$ global -sx message
message             8 test.sh              echo $message
message            11 test.sh          message=hello
----------------------

This behavior comes from the pygments syntax highlighter's limitation.
It cannot detect function references.

----------------------
$ pygmentize -l sh -f raw test.sh | grep '^Token.Name'
Token.Name.Builtin 'echo'
Token.Name.Variable '$message'
Token.Name.Variable 'message'
----------------------
