Visual Studio Code: Treat other extensions as HTML

Question

For the purposes of syntax highlighting and colouring and intellisense is it possible to treat other extensions (tpl, master, etc) as HTML?

I know it's possible on a file by file basis by pressing CTRL+SHIFT+P and selecting "Change Language Mode" BUT I want it to work off file extension, and not have to redo it every time I open a new file.

I also know it's possible for some languages by editing the json files in the plugins directory, BUT there doesn't seem to be one for HTML.

Update for VS Code 1.0:

There is a setting files.associations that can be used to assign file patterns to languages. For example:

"files.associations": {   "*.tpl": "html",   "*.master": "html" } 

Previous answer:

This is a commonly asked feature request and we are looking into this issue for the future.

As a workaround if you need to have a solutio now:

• close VS Code
• open C:\Users\<your name>\AppData\Local\Code\app-<latest-version>\resources\app\server\lib\mime.js
• find the object literal knownTextMimes
• for the file extension you want add the proper mime type
• for example '.tpl': 'text/html'
• save and restart code

Note: this change will not survive automatic updates but the hopes are that there is a better solution in the future update :)
