A Template for Crash-Resistant Toggle-Macros (JavaScript)

2010-10-07T00:51:42-07:00

JavaScript recipe 577418 by Eric Promislow (komodo, macro, snippet, template).

If you've followed my postings here lately (http://code.activestate.com/recipes/users/4166930/), you'll see that I've been playing with what I call "toggle macros", macros that toggle a state on and off, with different behaviors for each state. Unfortunately I found that it was easy to get Komodo to crash on shutdown. Meanwhile I wanted to build a framework to make it easier to build these.

This recipe accomplishes both. It looks like putting a listener on a view object can trigger this crash, but so can storing a method on a view object, even with a unique name. So while I wanted to use the "view.view_closing" event, I can't, and I notice no other core Komodo code is. The template instead uses a global hash, ko.extensions.togglers, to store the code objects. And now I'm not getting a crash.

node.js quicklog method to log to a file (JavaScript)

2010-08-11T05:08:57-07:00

JavaScript recipe 577351 by Trent Mick (logging, nodejs).

I tend to have a "quicklog" method for a few of the languages I'm working in to do logging when stdout/stderr isn't necessarily available (GUI app) or convenient (lots of other output on stdout, etc.). My usage with nodejs was while working on the node REPL. Log output to stdout interfered with the REPL.
