Sublime Text 3中的条件数学模式选项卡是否可以自动完成？

Question

I'd like to define, say, a snippet that will

1. Tab autocomplete with $$ to create a math mode expression if completion occurs outside of math mode, and
2. Autocomplete without the $$ if completion occurs within math mode.

For example, I'd like to define a completion for bb such that

1) bb expands to $\\mathbb{ }$

2) $bb$ expands to $\\mathbb{ }$ and not $$\\mathbb{ }$$ .

Is this possible?

Answer 1

Create two files in your Packages/User directory (select Preferences > Browse Packages... and open the User folder)

LaTeX.sublime-completions with the content:

{
    "scope": "text.tex.latex - meta.environment.math",

    "completions": [
        { "trigger": "bb\t\\\\mathbb{...}", "contents": "\\$\\\\mathbb{$1}\\$$0"},
        { "trigger": "bf\t\\\\mathbf{...}", "contents": "\\$\\\\mathbf{$1}\\$$0"}
    ]
}

LaTeX math.sublime-completions with the content:

{
    "scope": "text.tex.latex meta.environment.math",

    "completions": [
        { "trigger": "bb\t\\\\mathbb{...}", "contents": "\\\\mathbb{$1}$0"},
        { "trigger": "bf\t\\\\mathbf{...}", "contents": "\\\\mathbf{$1}$0"}
    ]
}

Now you can add other commands in a similar style.
