First there was: http://snipplr.com/view/15246/color-coded-svn-status

Then there was: http://snipplr.com/view/16540/color-coded-svn-status-v2

A few days ago, I found a handy script online that colorized the output of SVN status. It worked pretty well, but needed a little polish and a couple of tweaks to make it use more common Python idioms. As I continued to use it and fix bugs and inefficiencies, I ended up replacing nearly every line in the original, but it was still a great starting point.

Additional changes include ANSI word-wrapping, a configurable tab expansion feature (for better code alignment), the 'colorizedSubcommands' sequence so that only applicable commands get colorized, use of proper subprocess module calls so that piping through less will work (for example, try svn-color diff | less -r to see colorized diff output).

To use, stick it somewhere, make executable (`chmod 7

      headers["Access-Control-Allow-Methods"] = "POST, GET, PUT, DELETE, OPTIONS";

      headers["Access-Control-Max-Age"] = '86400'; // 24 hours
      headers["Access-Control-Allow-Headers"] = "X-Requested-With, X-HTTP-Method-Override, Content-Type, Accept";

用 JavaScript 实现的异步的 Lisp。颇有意思，备份一下。

Flask-SQLAlchemy Caching

The following gist is an extract of the article Flask-SQLAlchemy Caching. It allows automated simple cache query and invalidation of cache relations through event among other features.

Usage

retrieve one object

# pulling one User object

user = User.query.get(1)
