In http://tuhdo.github.io/c-ide.html#orgheadline2 which is about "Prerequisite"
- Or, helm + helm-gtags.
What does "Or" imply as the alternative to the combination "helm + helm+gtags"?
Is the alternative
- GNU Global
- GNU Global + ggtags
What are the relations between GNU Global and helm? Are GNU Global and helm alternatives to each other?
ggtags is a frontend of GNU Global, and is helm-gtags a frontend of helm?
What should I install according to the link?
Is it okay to install both combinations GNU Global + ggtags and helm + helm+gtags, and to use them both in the future?
Thanks.
