Re: Q on global/gtags with rust codes

[Makoto Harada]

Additional information.

It looks GPATH and GRTAGS are created correctly, but GTAGS are not....

This is true with and without modification of 
/usr/local/share/gtags/script/pygments_parser.py.
This is true with the latest global version(6.6.10) and old version(6.6.7).

===========================================
$gtags -d GPATH
 __.NEXTKEY     2
 __.VERSION      __.VERSION 2
./main.rs       1
1       ./main.rs

$gtags -d GRTAGS
 __.COMPACT      __.COMPACT
 __.COMPLINE     __.COMPLINE

 __.VERSION      __.VERSION 6

input   1 @n 5,2,2
io      1 @n 1,6
main    1 @n 3

trim    1 @n 9
unwrap  1 @n 7,2

$gtags -d GTAGS

 __.COMPRESS     __.COMPRESS ddefine ttypedef
