dict objects provide an __iter__ method for the iteration which gives you the keys, so calling keys directly is unnecessary, and isn't really a best practice. The only time you really need to call the keys is if there's a danger of the dict changing out from underneith you, either due to external forces or due to modification of the iterable in the loop. Iterations over os.environ are apparently subject to such changes, so they must continue to use keys(). As an aside, also switches a couple spots to using sorted() rather than creating a temporary list with keys() and sorting that.

BitBake Shell
|
|
|
|
IDEAS:
|
|
* list defined tasks per package
|
|
* list classes
|
|
* toggle force
|
|
* command to reparse just one (or more) bbfile(s)
|
|
* automatic check if reparsing is necessary (inotify?)
|
|
* frontend for bb file manipulation
|
|
* more shell-like features:
|
|
- output control, i.e. pipe output into grep, sort, etc.
|
|
- job control, i.e. bring running commands into background and foreground
|
|
* start parsing in background right after startup
|
|
* ncurses interface
|
|
|
|
PROBLEMS:
|
|
* force doesn't always work
|
|
* readline completion for commands with more than one parameters
