Snippet's dropdown for LaTeX

[hbar]

Hey there,

I’m using SublimeText 3 with LaTeXTools and I’d like to have a dropdown/pop-up appear for available snippets. For example, if I type “figure”, I want a dropdown to appear, letting me know that I’ve 2 available snippets for that word: “figure” and “bfigure”.

Is there a way to do this? I would expect this to be default behaviour.

I wrote some code a while ago that will display autocompletions for snippets tab triggers:

I want all my snippets to open in an "autocomplete" list after typing custom code (3 brackets - [[[ )

Here is a generic solution that will work with your [[[ tab trigger prefix to show auto completions: (It is Python code, to be saved as a plugin with a .py extension in your Packages/User folder) import sublime, sublime_plugin from xml.etree import ElementTree class AutoCompleteSnippetTriggersListener(sublime_plugin.EventListener): def on_query_completions(self, view, prefix, locations): snippets = sublime.find_resources('*.sublime-snippet') completions = [] word_s…

I guess you’d want to change the if not triggerText.startswith(prefix): to if not prefix in triggerText:, so that your bfigure snippet would show when you type figure. Also, you’d have to add the text.tex scope to your auto_complete_selector setting, otherwise the suggestions would only show when you explicitly trigger autocompletion using the menu or keybinding.

That does not work for me, though truth be told, I’ve no idea what I’m doing.

After changing your script (as you suggested) and saving it in ~/.config/sublime-text-3/Packages/User, what am I supposed to do with it?

Also, I changed

// Controls what scopes auto complete will be triggered in
“auto_complete_selector”: “meta.tag - punctuation.definition.tag.begin, source - comment - string.quoted.double.block - string.quoted.single.block - string.unquoted.heredoc”,

to

// Controls what scopes auto complete will be triggered in
“auto_complete_selector”: “meta.tag - punctuation.definition.tag.begin, source - comment - string.quoted.double.block - string.quoted.single.block - string.unquoted.heredoc - text.tex”,

(just added “text.tex”)

Is this correct? Because absolutely nothing changed. Still not getting the dropdown for latex files.

Basically, what I want is to enable auto-complete for latex snippets. Does one really need to get into scripts and all that to do that?

[kingkeith]

apologies, turns out you shouldn’t need the script. I had thought that snippets aren’t shown by autocompletion automatically, but it seems they are - the script I linked to is related to when the snippet has a tab trigger that isn’t a word, in which case maybe it’s not shown by default.

So it should be enough to change your auto_complete_selector to:
meta.tag - punctuation.definition.tag.begin, source - comment - string.quoted.double.block - string.quoted.single.block - string.unquoted.heredoc, text.tex

note the comma before text.tex. Minus is a “negation”, comma is an “or”.

@kingkeith, thank you. That worked perfectly.

Would be cool if typing “figure” would also have “bfigure” in the dropdown, but it’s good enough as it is.

Thank you again
