I was wondering if it was possible to run a custom script on save based on certain file names in textmate. For example I'd like to auto compile a C program sometime on save.

It's actually fairly easy to do this using a custom command in a bundle.

Here's how to make a simple command:

  • Open up the bundle editor, and find the bundle you want to add to.
  • Create a "New Command" using the button on the bottom left of the editor. Name it appropriately, and set its scope to source.c.
  • Set the action dropdown to "Key Equivalent", and set the shortcut Cmd + S.
  • Change the "Save" dropdown to "Current File".
  • Enter your command, and set the input and output dropdowns appropriately. Input will be piped to STDIN if I remember correctly.
  • Reload TextMate's bundles.

That's it. You should now have a command which saves the file, and runs a command.

You can probably do something with TextMate commands by using a macro in a similar way.


As far as I know, there's no way to do this as you described, for all save situations (i.e., using Command-S, selecting File->Save, etc.).

You might be able to create a custom bundle item that saves the document and executes your script, and assign it Command-S, so that it runs when you use that keyboard shortcut.


you can trigger a command after save via callback.document.did-save semantic class. This works on TextMate2+

  • Where does the semantic class can be added ? It can be useful when the save happens automatically and not by a key press.

  • Found it : that is one of the input of a command form.
