This Sublime Text package provides support for working with tags generated by Exuberant CTags or Universal CTags.
ctags
command is searched for on the system PATH. It works by doing a binary
search of a memory-mapped tags file, so it will work efficiently with very large
(50MB+) tags files if needed.
The easiest way to install is using Package Control. It's listed as CTags
.
Command Palette
using menu item Tools → Command Palette...
Package Control: Install Package
CTags
and hit Enter
.zip
CTags
Packages
directory,
which can be found using the menu item Preferences → Browse Packages...
Go to your Sublime Text Packages directory and clone the repository using the command below::
git clone https://github.com/SublimeText/CTags
To install ctags use your package manager.
For Debian-based systems (Ubuntu, Mint, etc.)::
sudo apt-get install exuberant-ctags
or
sudo apt-get install universal-ctags
For Red Hat-based systems (Red Hat, Fedora, CentOS)::
sudo yum install ctags
The default ctags
executable in OSX does not support recursive directory
search (i.e. ctags -R
). To get a proper copy of ctags, use one of the
following options:
Ensure that the PATH
is updated so the correct version is run:
which ctags
doesn't point at ctags in /usr/local/bin
, make sure
you add /usr/local/bin
to your PATH
ahead of the folder
which ctags
reported.ctags
executable to the settings,
under command
. If you have Xcode / Apple Developer Tools installed this
path will likely be /usr/local/bin/ctags
.Download Exuberant CTags binary or Universal CTags binary
Extract ctags.exe
from the downloaded zip to
C:\Program Files\Sublime Text
or any folder within your PATH so that
Sublime Text can run it.
Alternatively, extract to any folder and add the path to this folder to
the command
setting.
This uses tag files created by the ctags -R -f .tags
command by default
(although this can be overridden in settings).
The plugin will try to find a .tags
file in the same directory as the
current view, walking up directories until it finds one. If it can't find one
it will offer to build one (in the directory of the current view)
If a symbol can't be found in a tags file, it will search in additional
locations that are specified in the CTags.sublime-settings
file (see
below).
If you are a Rubyist, you can build a Ruby Gem's tags with the following script:
require 'bundler'
paths = Bundler.load.specs.map(&:full_gem_path)
system("ctags -R -f .gemtags #{paths.join(' ')}")
To open CTags.sublime-settings
Command Palette
using menu item Tools → Command Palette...
Preferences: CTags Settings
and hit Enter
filters
will allow you to set scope specific filters against a field of
the tag. In the excerpt above, imports tags like from a import b
are
filtered:
'(?P<symbol>[^\t]+)\t'
'(?P<filename>[^\t]+)\t'
'(?P<ex_command>.*?);"\t'
'(?P<type>[^\t\r\n]+)'
'(?:\t(?P<fields>.*))?'
extra_tag_paths
is a list of extra places to look for keyed by
(selector, platform)
. Note the platform
is tested against
sublime.platform()
so any values that function returns are valid.
extra_tag_files
is a list of extra files relative to the original file
command
is the path to the version of ctags to use, for example::
"command" : "/usr/local/bin/ctags"
or:
"command" : "C:\\Users\\<username>\\Downloads\\CTags\\ctag.exe"
The rest of the options are fairly self explanatory.
By default, Sublime will include ctags files in your project, which causes
them to show up in the file tree and search results. To disable this behaviour
you should add a file_exclude_patterns
entry to your
Preferences.sublime-settings
or your project file. For example:
"file_exclude_patterns": [".tags", ".tags_sorted_by_file", ".gemtags"]
If there are any problems or you have a suggestion, open an issue, and we will receive a notification.
