Hello,
I believe there is a fundamental solution and a workaround
for this issue.
1. Fundamental solution
Rewrite the code to operate according to the tag files,
in accordance with the established rule.
2. Workaround
Use project-based gtags.conf. You can reference a shared
gtags.conf within the project.
$ cp /usr/local/share/gtags/gtags.conf .
$ vi gtags.conf
+-----------------------------
|default:\
| :tc=native:
+-----------------------------
|
v
+-----------------------------
|default:\
| :tc=universal-ctags:
+-----------------------------
$ gtags
$ global -f global-f_bug.c
$ global -f global-f_bug.c -r
---
I originally chose the current parser-based implementation
because I believed it was efficient. However, the time may
have come to reconsider that.
What do you think?
