Version 1.6 adds a very minor feature, plus a significant improvement in the parser. All words (command, arguments, filenames for IO redirection, arguments for job handlers) now support all the same expansions. This was previously inconsistant. Also, quoting is now better for limiting expansions. The only new feature is temporary environment variables for a single command via a single back-quote after command args ("command arg arg `NAME=val"). Also up-arrow now works, if you compile with readline.

Version 1.5.2 fixes some bugs, mostly related to env args for scripts. Also, "setenv -ci" now correctly resets all internal settings to defaults. And... mpsh-nice-def sets default nice value for background jobs.

Fri Apr 25 17:36:45 EDT 2014

Released version 1.5. Lots of bug fixes and some new features and tweaks:

"macro" command.

"show-path" command.

Give a job an arbitrary name.

setenv -c[aih] option.

Internal setting: mpsh-exp-nl

Boolean internal settings take "true" or "false" as well as "1" or "0".

Job handler variables no longer take a leading "!". Sorry about that.

Released version 1.3 to the public. Added the "alias" command, and more fields to command history and command history display. (The "parsed" field is not complete. It handles general argument expansion (env, glob, etc.) but it is incomplete when dealing with complex pipelines.)

Minor revision update due to the discovery of a handful of bugs.

Released version 1.2 to the public. Fixed some bugs, added a few interesting features to command history, and confirmed that it compiles properly under OSX. (Building under OSX requires gcc. It will not work with clang. In particular, that means that a "gcc" command that actually invokes clang will not work.)
