This page will be is about editing ConTeXt source in (g)vimVim, gVim, MacVim, NeoVim, and other Vim clones. Some of the described features are available only in Vim v8.0.0047 or later.

Tex TeX (plain texPlain TeX), latex LaTex and context ConTeXt all use the <code>.tex</code> extension for files , which makes it difficult to detect the filetype based on the extension. From Vim 7 onwards, vim Vim does some intelligent checking to see it the file is <code>plaintex </code> or <code>latex </code> or <code>context</code>.

If the first line of a <code>*.tex </code> file has the form

then this determined determines the file type: <code>plaintex </code> (for plain Plain TeX), <code>context </code> (forConTeXt), or <code>tex <code> (for LaTeX). Otherwise, the file is searched for keywords tochoose <code>context </code> or <code>tex</code>. If no keywords are found, it defaults to <code>plaintex</code>.You can change the default by defining the variable <code>g:tex_flavor </code> to the format

* If you use ConTeXt most of the time, but occasionally use latex LaTeX or plaintexPlain TeX, you can add the following to your <code>.vimrc</code>

* If you only use ConTeXt, you can add the following lines to <code>filetype.vim</code>:

so the next time you open a <code>*.tex</code> file, vim Vim will recognise always recognize it as a context fileConTeXt document.
