Completions
Command completion, snippets, etc.
By default, ST provides a number of snippets for LaTeX editing; the LaTeXTools plugin adds a few more. You can see what they are, and experiment, by selecting Tools | Snippets | LaTeX and Tools | Snippets | LaTeXTools from the menu.
In addition, the LaTeXTools plugin provides useful completions for both regular and math text; check out files LaTeX.sublime-completions and LaTeX math.sublime-completions in the LaTeXTools directory for details. Some of these are semi-intelligent: i.e. bf expands to \textbf{} if you are typing text, and to \mathbf{} if you are in math mode. Others allow you to cycle among different completions: e.g. f in math mode expands to \phi first, but if you hit Tab again you get \varphi; if you hit Tab a third time, you get back \phi.
CWL support
LaTeXTools ships TeXStudio Completion Word Lists to support command completions.
Additional user defined CWL files can be placed in Packages/User/cwl directory.
By default, as soon as one starts typing a command, e.g., \te, a popup is shown displaying possible completions, e.g. including \textit and the like.
The following settings are provided to control LaTeXTools cwl behavior.
cwl_list: a list ofcwlfiles to loadcwl_autoload: controls loading completions based on packages in the current document in addition to those specified in thecwl_list. Defaults totrue, so you only need to set this if you want to disable this behavior.command_completion: when to show that cwl completion popup. The possible values are:prefixed(default): show completions only if the current word is prefixed with a\always: always show cwl completionsnever: never display the popup
env_auto_trigger: iftrue, autocomplete environment names upon typing\begin{or\end{(default:false)
User defined completions
LaTeXTools provides support for custom user-defined completions through modification of the LaTeX.sublime-completions file. The user modified version should be placed in your User directory, otherwise it will be overwritten by future updates.
