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 🙂
