Note, however, that this could potentially more than double the size of the tag file. Note that the name of each source file will be recorded in the tag file exactly as it appears on the command line. The second command can be used to search for any tag, regardless of the file that is currently opened. These latter features may be used to override decisions made by apt-get's conflict resolution system. The full form of kind-spec is in the form of a single letter, a comma, a name without spaces , a comma, a description, followed by a separator, which specify the short and long forms of the kind value and its textual description displayed using --list-kinds. You can work around many such problems by using the -I option. Note: This option is not supported on all platforms at present.
This prints out information on option processing and a brief message describing what action is being taken for each file considered by ctags. Most options may appear anywhere on the , affecting only those files which follow the option. Note that the original vi required sorted tags. See the --list-languages option for a complete list of the built-in language names. . For a complete list of supported languages, the names by which they are recognized, and the kinds of tags that are generated for each, see the --list-languages and --list-kinds options.
Although ctags has been designed to handle certain common cases, this is the single biggest cause of reported problems. Note that the option files are read in line-oriented mode in which spaces are significant since shell quoting is not possible. Ctags also supports many besides C, so you may find it useful for future projects. There are two main solutions for tag jumping: and. I'm getting into C development under linux, however I'm strungling with correctly setting up ctags to work with vim.
Significantly reduces the size of the resulting tag file. It is available if the output of the --help option includes this option. Note that if an extension supplied to this option is not already mapped to a particular language see , above , you will also need to use either the --langmap or --language-force option. If this option is specified more than once, only the last will apply. The meaning of each flag: f: Include an entry for the base file name of every source file e. In this case, you can run the following two commands to list all of the uses of a given : M-x tags-apropos Tags apropos regexp : This will display a list of the tag definitions in another buffer.
This may allow easier location of a specific tags when multiple occurrences of a tag name occur in the tag file. There are lot many cscope. This is to keep the ctags program from misinterpreting certain constructs and thus misrepresenting those particular tags in the generated file think preprocessor macros or compiler directives or not even placing them into the output file at all. A file extension is specified by preceding the extension with a period e. Alternatively, you may wish to use to find function and structure definitions, or just use the third step of the Vim instructions below. See your article appearing on the GeeksforGeeks main page and help other Geeks. If flags is preceded by either the ' +' or ' -' character, the effect of each flag is added to, or removed from, those currently enabled; otherwise the flags replace any current settings.
If a language was identified, the file is opened and then the appropriate language is called to operate on the currently open file. Running the script will generate a directory and a file: cscope and cscope. A simple apt - get install cscope or similar command will do just fine here. You can also give the autocomplete a try by starting to type the name of a function or variable. The possible keys and the meaning of their values are as follows: access Indicates the visibility of this class member, where value is specific to the language.
This extension field is presently supported only for C-based languages and does not include the return type. Also, the special value auto indicates that the language should be automatically selected which effectively disables this option.

Their presence in the lines of the tag file are controlled by the --fields option.
Processing triggers for man-db 2. For more information on the regular expressions used by ctags, see either the regex man page, or the info documentation for regex e.

This can be a pain in the ass to run regularly, so you might like to bind it to a vim keyboard shortcut so you can run it every so often, or add to run ctags every time you check out, commit, or fetch with git. This option is specifically provided to handle special cases arising through the use of preprocessor. File names read using this option are processed following file names appearing on the command line.
Those keep ctags from being fooled. Each package is a package name, not a fully qualified filename. Therefore, if the path you specified on the command line was relative to the current directory, then it will be recorded in that same manner in the tag file. This option only affects how the scoping of a particular kinds of tags is interpreted i. The optional behaviors are controlled with the --fields option.
