(This post is from my old, old, super old site. My views have changed over the years, hopefully my writing has improved, and there is now more than a handful of folks reading my site. Enjoy.)

JSCocoaCodaLoader is a silly name, isn't it?

Coda 1.6 was just released, and it's got support for 3rd party plug-ins now. Woo! And of course I had to go and write a loader for Lua like I did for VoodooPad. Wait no- not Lua, I mean Python. Wait, um... no, not Python this time either. Ok, I picked Javascript, using the cocoa-javascript bridge from JSCocoa.

What this plugin does, is enables you to write plugins that work in Coda, but in Javascript.

Here's an example:

// Uppercase.js codaPluginsController = JSCocoaLoaderPlugIn.codaPluginsController(); var tv = codaPluginsController.focusedTextView(null); var selectedText = tv.selectedText();

if (selectedText != null) { tv.insertText_(selectedText.uppercaseString()) }

Put that in a file named "Uppercase.js", inside ~/Library/Application Support/Coda/JSPlug-ins/ (which is different than ~/Library/Application Support/Coda/Plug-ins/, which is where the normal Coda plugins go), and it'll show up under the Plug-ins menu.

Here's another one, for pasting an href around some selected text:

//PasteURL.js codaPluginsController = JSCocoaLoaderPlugIn.codaPluginsController(); var tv = codaPluginsController.focusedTextView(null); var selectedText = tv.selectedText();

if (selectedText != null) { // for simplicity, no real checking is done here var clipboard = NSPasteboard.generalPasteboard().stringForType(NSStringPboardType); tv.insertText_("<a href="" + clipboard + "">" + selectedText + "</a>") }

You can download the plugin: JSCocoaLoader.codaplugin.zip, or check out the source from my svn repository. Unzip and put the JSCocoaLoader.codaplugin in ~/Library/Application Support/Coda/Plug-ins/. If it's not there already, create it.

Tada!
