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.

This is guaranteed to always contain the string “Exuberant Ctags”. Some examples will illustrate this point. Eliminates failures to find tags because the line defining the tag has changed, mxnual the pattern match to fail note that some editors, such as vimare able to recover in many such instances.

Print a tabular, human-readable cross reference xref file to standard output instead of generating a tag file. Switch to the new buffer C-x oscroll through the list of definitions to the one that you want, then press Enter to open the file.

Find the first definition of TAG. The default tag is the identifier under the cursor. Causes ctags to behave as a filter, reading source file names from standard input and printing their tags to standard output on a file-by-file basis.

This option must appear before the first file name.

Ctags Tutorial

Ctags is capable of generating different kinds of tags for each of many different languages. The parameter flags is a set of one-letter flags, each representing one kind of extra tag entry to include in the tag file.

Ctahs pattern is interpreted as a Posix extended regular expression default. This can be useful if the size of a temporary file becomes too large to fit on the partition holding the default temporary directory defined at compilation time. Both branches cannot be followed, or braces become unbalanced and ctags would be unable to manyal sense of the syntax. Ctags is a tool that makes it easy to navigate large source code projects.


Note that the name of each source file will be recorded in the tag file exactly as it appears on the command line. The foldcase value specifies case insensitive or case-folded sorting.

The regular expression defined by this option is added to the current list of regular expressions for the specified language unless the parameter is omitted, in which case the current list is cleared.

The actual file names placed into the tag file will have the same leading path components as the preprocessor output file, since it is assumed that the original source files are located relative to the preprocessor output file unless, of course, the line directive specifies an absolute path.

This tag file allows these items to be quickly and easily located by a text editor or other utility. Note that the original vi 1 required sorted tags. The default is no. Alternatively, you manaul wish to use cscope to find function and structure definitions, or just use the third step of the Vim instructions below. Also ex 1vi 1elvisor, better yet, vimthe official editor of ctags. When you’re done, instead of jumping back ctats in the tag stack, close the new buffer C-x k.

This may permit an application reading the output of ctags to determine when the output for each file is finished. The default tag file created by ctags. Lists the tag kinds recognized for either the specified language or all languages, and then exits.

This option is off by default. Note, however, that this could potentially more than double the size of the tag file. Indicates that the tag has file-limited visibility. This option is quite esoteric and is empty by default.

Note You may see messages like “Warning: If the first character in the list is a plus sign, then the extensions in the list will be appended to the current list; otherwise, the list will replace the current list.

To restore the default language mappings for all a particular language, supply the keyword “default” for the mapping. Ctags with Vim Note These commands were tested with Vim 7.


Lists the file extensions and file name patterns which associate a file name with a language for either the specified language or all languages, and then exits. The example above uses “CLASS” as a preprocessor macro which expands to something different for each platform. The pattern is interpreted as a Posix basic regular expression. Therefore, the first two characters of these tags are used a magic number to detect a tag file for purposes of determining whether a valid tag file is being overwritten rather than a source file.

The parameter kinds is a group of one-letter flags designating kinds of tags particular to the language to either include or exclude from the output. In addition, information on the scope of the tag definition may be available, with the key portion equal to some language-dependent construct name and its value the name declared for that construct in the program. Indicates whether symbolic links if supported should be followed. This option is enabled by default. This permits running ctags on all files in either a single directory e.

In addition, the special value auto indicates that the language should be automatically selected which effectively disables this option. For more commands, see the Tags topic in the Emacs info document. Each line of the file is read as one command line parameter as if it were quoted with single quotes. Ctags Tutorial Ctags is a tool that makes it easy to navigate large source code projects. On Unix-like hosts where mkstemp is available, the value of this variable specifies the directory in which to place temporary files.

Indicates whether the tag file should be sorted on the tag name default is yes.
