See http://code.google.com/p/cmdln/source/list for the very latest.

v1.2.0

•  Issue 3 : Raise upper bound width for left column in "Commands" and "help topics" lists in help output to 30. Also fix buglet in that column formatting.
•  Issue 7 : add man_sections_from_cmdln(...) for generating decent man page content automatically from a Cmdln subclass instance. See ManPageGeneration for an overview.

v1.1.3

• Stop using string.whitespace because it can be an 8-bit string with non-ASCII chars in it, leading to potential UnicodeDecodeErrors. See Komodo Bug 81316.

v1.1.2

• Some Python 2.6-ification. No functional change.

v1.1.1

•  Issue 1 : fix readline-based completion and history (from Joshua Gallagher).
• Experimental automatic bash completion support. See r8 for details: svn diff -r7:8 http://cmdln.googlecode.com/svn/trunk/cmdln.py
• Some minor improvements to line2argv processing (r7).
• Fix ${help_list} layout problems and more closely follow optparse option list help output (r4).
• Moved project to Google Code.

v1.0.0

• [backward incompat] Cmdln.main() no longer takes an optparser argument. Top-level option parsing has been changed so that top-level options for a Cmdln subclass can more naturally be defined and handled on the class definition. Changes:
• Cmdln.main() calls self.get_optparser to get an option handler. Subclasses should overload this method for custom top-level options.
• After option parsing, but before sub-command handling, the self.postoptparse() hook is called.
• Add a version attribute on Cmdln subclasses. If set, the default top-level option parser will have a --version attribute.
• [backward incompat] Simplify the StopProcessing/opts.stop handling for option handling in subcommands. The "opts" argument to do_* sub-command functions will no longer have a "stop" value. StopProcessing is now called StopOptionProcessing. This shouldn't affect simple usage of cmdln.py.

v0.8.3

• Fix a bug where errors with passing an incorrect number of args to functions in do_foo() implementations would be masked.

v0.8.2

• Remove the implicit prefixing of a command's help string with ${cmdname}: . This can be surprising for the case of a help_FOO function without an associated do_FOO function.

v0.8.1

• Work on getting started docs.
• Improve the ${command_list} output to better handle long command names.
• Add ${cmd_usage} template var: inferring a usage from the command handler signature.
• Add ${option_list} template var for the option table for the whole Cmdln class and add this to the default help output.

v0.8.0

• First version at which I started stabilizing it for public release. I've been batting around modules to improve on cmd.py for a long time -- variously called tm/cmd.py, 'cmd2.py', 'tmCmd.py', 'linecmd.py', 'argvcmd.py', etc.
