Which Mac text editor has the ability to tail or watch for changes in files?

I was hoping to utilize this in TextMate, but I couldn't find any features aside from the Show Web Preview. This feature allows me to set the interval for updating the page, but it doesn't support watching files or applying syntax highlighting.

An example of what I am looking for is similar to the CoffeScript Try Now feature, where I can type on one side and see the corresponding JavaScript file on the other side.

My ideal scenario would involve opening a .coffee file and running coffee -watch in the terminal to track any changes made to that specific file. Then I could have another window in my text editor that continuously updates the generated .js file.

Something like this: [link to visual representation]

If I haven't explained myself clearly, please let me know. Basically, I want to see real-time changes to my files after running a script, with syntax highlighting and other features if possible.

I'm currently testing out the kaleidoscope app, which has great visualization capabilities but lacks editing and syntax highlighting features. Something similar with these functionalities would be ideal.

Cheers!

Answer №1

If you want to accomplish both tasks, Emacs is a great option (especially when running it as a Cocoa app).

ediff in Emacs functions similarly to Kaleidoscope, allowing you to edit files without interrupting the diff process. By default, the versions are displayed one above the other, but you can use | to toggle to side-by-side view, and m to expand to full screen width (although this may not work perfectly with multiple monitors in some versions of Emacs.)

To tail/auto-revert content, Emacs offers auto-revert-mode and auto-revert-tail-mode features.

If you need help mastering Emacs, websites like emacswiki.org and blogs like Mastering Emacs and M-x all-things-emacs (which shares useful screencasts) are excellent resources to explore.

To access the log file on OSX, you can utilize the Console log viewer utility, which is designed for monitoring system logs. While it may not display differences, it does offer similar functionality to the tail -f command.
