## Classes

A dict that automatically creates values for missing keys. This is the same as collections.defaultdict in the Python standard library. It's provided here for Python 2.4, which doesn't have that class.

When you try to read a key that's missing, I call missing_func without args to create a value. The result is inserted into the dict and returned. Many Python type constructors can be used as missing_func. Passing list or set creates an empty dict or set. Passing int creates the integer 0. These are useful in the following ways:

>> d = defaultdict(list);  d[ANYTHING].append(SOMEVALUE)
>> d = defaultdict(set);  d[ANYTHING].include(SOMEVALUE)
>> d = defaultdict(int);  d[ANYTHING] += 1


## Functions

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
