Run a script on save in textmate

Question

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.

Answer 1

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.

Answer 2

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.
