How can I make all new files open with a specific grammar or syntax?


Newly created files in Atom are always “Plain Text”. Let’s say I want to change this so that new files will automatically be in another language, for example “Shell Script (Bash)”.

The following code, added to your, will do this:

atom.workspace.observeTextEditors (editor) ->
  original = editor.getGrammar()
  if original? and original is atom.grammars.grammarForScopeName('text.plain.null-grammar')

Things to note:

  • The file is where you can customize Atom without having to write a package
  • The observeTextEditors method sets a callback that is called upon each TextEditor creation for currently open and future editors
  • The code above:
    1. Checks the grammar that the editor was created with
    2. If and only if it is the default (“null”) grammar, it sets the editor’s grammar to the Shell grammar
