add support for GNU Global?

[linusboyle]

g:Lf_Ctags doesn't work for gtags,no matter what I set it to be,gtags or global or gtags-cscope.It seems only ctags is supported right now. Anyway,I can use cscope and just lack some fuzzy and regex things,but maybe you can enhance this great plugin?

I think fuzzy find symbol reference of gtags (or some other provider) is also very useful feature.

[linusboyle]

Well, it's not difficult to script myself if #144 is implemented. Likewise the ctags support will be unnecessary then

[kgfly]

GNU Global support is great. But I think ctags support is a fundamental need though~

[COMMON_OPTIONS]: [--reverse] [--stayOpen] [--input <INPUT> | --cword]
                  [--top | --bottom | --left | --right | --belowright | --aboveleft | --fullScreen]
                  [--nameOnly | --fullPath | --fuzzy | --regexMode] [--nowrap]
 

optional arguments:
  -h, --help            show this help message and exit

specific arguments:
  --update              Create tag files if tag files do not exist, update the tag files otherwise.
  --remove              Remove the tag files generated.
  --accept-dotfiles     Accept files and directories whose names begin with a dot. By default, gtags
                        ignores them.
  --skip-unreadable     Skip unreadable files.
  --gtagsconf <FILE>    Set environment variable GTAGSCONF to <FILE>.
  --gtagslabel <LABEL>  Set environment variable GTAGSLABEL to <LABEL>.
  --skip-symlink [<TYPE>]
                        Skip symbolic links. If type is 'f' then skip only symbolic links for file, else
                        if 'd' then skip only symbolic links for directory. The default value of type is
                        'a' (all symbolic links).
  --gtagslibpath <PATH> [<PATH> ...]
                        Specify the paths to search for library functions.
  -d <PATTERN>, --definition <PATTERN>
                        Show locations of definitions.
  -r <PATTERN>, --reference <PATTERN>
                        Show reference to a symbol which has definitions.
  -s <PATTERN>, --symbol <PATTERN>
                        Show reference to a symbol which has no definition.
  -g <PATTERN>, --grep <PATTERN>
                        Show all lines which match to the <PATTERN>.
  --by-context          Decide tag type by context at cursor position. If the context is a definition of
                        the pattern then use -r, else if there is at least one definition of the pattern
                        then use -d, else use -s. Regular expression is not allowed for pattern.
  -i, --ignore-case     Ignore case distinctions in the pattern.
  --literal             Execute literal search instead of regular expression search.
  --path-style <FORMAT>
                        Show path names using <FORMAT>, which may be one of: `relative`, `absolute`,
                        `shorter`, `abslib` or `through`. `relative` means relative path. `absolute`
                        means absolute path. `shorter` means the shorter one of relative and absolute
                        path. `abslib` means absolute path for libraries (GTAGSLIBPATH) and relative path
                        for the rest. `through` means the relative path from the project root directory
                        (internal format of GPATH). The default is `relative`.
  -S <DIR>, --scope <DIR>
                        Show only tags which exist under <DIR> directory.
  --recall              Recall last search. If the result window is closed, reopen it.
  --match-path          Match the file path when fuzzy searching.
  --append              Append to the previous search results.
  --current-buffer      Show tags in current buffer.
  --all-buffers         Show tags in all listed buffers.
  --all                 Show tags in the whole project.
  --result <FORMAT>     Show result using format, which may be one of: `ctags`(default), `ctags-x`,
                        `ctags-mod`.
  --auto-jump [<TYPE>]  Jump to the tag directly when there is only one match. <TYPE> can be 'h', 'v' or
                        't', which mean jump to a horizontally, vertically split window, or a new tabpage
                        respectively. If <TYPE> is omitted, jump to a position in current window.

common arguments:
  --reverse             show results in bottom-up order
  --stayOpen            don't quit LeaderF after accepting an entry
  --input <INPUT>       specifies INPUT as the pattern inputted in advance
  --cword               current word under cursor is inputted in advance
  --top                 the LeaderF window is at the top of the screen
  --bottom              the LeaderF window is at the bottom of the screen
  --left                the LeaderF window is at the left of the screen
  --right               the LeaderF window is at the right of the screen

  --fullScreen          the LeaderF window takes up the full screen
  --nameOnly            LeaderF is in NameOnly mode by default
  --fullPath            LeaderF is in FullPath mode by default
  --fuzzy               LeaderF is in Fuzzy mode by default
  --regexMode           LeaderF is in Regex mode by default
  --nowrap              long lines in the LeaderF window won't wrap
  --next                Jump to the next result.
  --previous            Jump to the previous result.

If [!] is given, enter normal mode directly.

@Yggdroot Thanks for implementing this feature.
I think maybe I should take time to have a test of it, but at least the major problem is solved.Closed

[xaljer]

Can Leaderf gtags use exist gtags files managed by other vim plugin like gen_tags.vim?

[Yggdroot]

@xaljer No. LeaderF can manage the gtags files very well.

[xaljer]

so Leaderf can auto update tags when file is changed? that sounds great. I do not find an option to specify location of tag file. where are gtags files, and can i change it?

[linusboyle]

where are gtags files, and can i change it?

@xaljer the tag file is in the cache folder you set and of course you can change it.

So far my experience with gtags feature is excellent. Despite the lack of several other cscope interface query methods such as include hierarchy, leaderf functions even better than gutentags. Haven't test and don't know if leaderf can update the database on writeout, but otherwise a single line vimscript can achieve this.
