How do I make a default syntax by filetype in Atom text editor?

Question

I want my .ejs files to have html syntax, however, it always opens the files as Plain Text.

In sublime you can choose "Open all with current extension as..." then choose your syntax.

I see that you can change the syntax in the left bottom corner

How do you open files with a certain type with a specific syntax?

Answer 1

This is now in Atom core, you don't need that file-types package any more.

Where I work, we use .phl for a certain kind of PHP file. To tell Atom about this, first find the language's Scope Name (e.g. text.html.php ), then edit config.cson like so:

core:     customFileTypes:       "text.html.php": [         "phl"       ]     themes: [ // snip 

You can find this file at ~/.atom/config.cson, or from the Settings window click the "Open Config Folder" button.

It's easy to get wrong, as evidenced by the many errors people made on the GitHub issue for the feature.

Answer 2

Edit: since the time I wrote this answer, this functionality has been added to Atom core, see this answer for details.

file-types Atom package

(https://atom.io/packages/file-types)

It does exactly what the title question asks for: you can define new file extensions for existing languages with a simple edit of the config.cson file.
