The goal of this project is to maintain a common/unified space where people interested in improving ctags can work together. This guide is primarily intended for. The ctags utility shall be provided on systems that support the the Software Development Utilities option, and either or both of the C- Language Development . Contribute to SublimeText/CTags development by creating an account on GitHub . Alternatively, the plugin can be installed manually using one of the following.

Find the first definition of TAG. Cfags from file a list of file names for which tags should be generated. Note that the original vi 1 required sorted tags. Say yes when prompted to load the really big tags file. A routine signature in its complete form specifies the return type of a routine and its formal argument list.

Even the list of all definitions given by tags-apropos may be too large to find the definition that you’re looking for. Only options will be read from these files. Indicates a preference as to whether code within an ” if 0″ branch of a preprocessor conditional should be examined for non-macro tags macro tags are always included.

Therefore, use new lines to indicate separate command-line arguments. Sometimes Etags will find multiple definitions for a given tag; when this is the case, use the third command to jump through the possible definitions until you find the one that you want. If you are not on forkbomb or attumake sure that the system you are using has “Exuberant Ctags” installed, rather than the original “Ctags,” by running ctags –version.


The default is no. Note that spaces separating the single-letter options from their parameters are optional. Finally, use the fourth command to jump back up in the tag “stack. All of the information in this tutorial, and lots more advanced information, can be found there.

When the identifiers listed are simple identifiers, these identifiers will be ignored during parsing of the source files. Enable etags mode, which will create a tag file for use with the Emacs editor. Ctags will also try to specially handle arguments lists enclosed in double sets of parentheses in order to accept the following conditional construct:. The actual form of the qualified tag depends upon the language from which the tag was derived using a form that is most natural for how qualified calls are specified in the language.

Unless modified by flagsregexp is interpreted as a Posix extended regular expression. Basically, this option is best used when the source code to which it is applied is not subject to change.

Although ctags has been designed to handle certain common cases, this is the single biggest cause of reported problems. Most options may appear anywhere on the command line, affecting only those files which follow the option. If this is a problem, use a configuration file instead. It shouldn’t take too long, and it’s worth your time. Note that the option files are read ctays line-oriented mode in which spaces are significant since shell quoting is not possible.

Once the tag file is built, the following commands exercise the tag indexing feature:. Older implementations of ctags tended to rely upon certain formatting assumptions in order to help it resolve coding dilemmas caused by preprocessor conditionals. Vi 1 and its derivatives e.

Ctags Tutorial

Indicates the type, cctags kind, of tag. If the sort utility of the operating system is being used, it will generally observe this variable also. Alternatively, you may wish to use cscope to find function and structure definitions, or just use the third step of the Vim instructions below. Ctags will make it much easier to find the Linux kernel files that you have to modify for your CSE projects.


After creating or appending to the tag file, it is sorted by the tag name, removing identical tag lines. This scope entry indicates the scope in which the tag was found. The second command can be used to search for any tag, regardless of the file that is currently opened. This has four advantages: On platforms which support it, if the name of a file is not mapped to a language and the file is executable, the first line of mqnual file is checked to see if the file is a “!

Also ex 1vi 1elvisor, better yet, vimthe official editor of ctags.

This key has no corresponding value. For example, to specify that only files with extensions of.

If this environment variable exists, manua will be expected to contain a set of default options which are read when ctags starts, after the configuration files listed in FILESbelow, are read, but before any command line options are read. Each line of the file is read as one command line parameter as if it were quoted with single quotes.

Add pattern to a list of excluded files and directories. When disabled, symbolic links are ignored.
