Hi Travis,

That looks pretty awesome. I've asked the common-lisp.net admin to give you an account and add you to the project. You'll need to send your PGP public key to admin@common-lisp.net.

Out of curiosity, what kind of production system are you using Parenscript for?

Thank you, Vladimir

Greetings,

I've made a number of improvements to the ParenScript code base. What's the best way for us to merge these changes into the darcs repo on common-lisp.net?

Most of the updates fall into five basic broad categories:

• Rewriting PS special forms to better match their CL equivalents.

For example, DO now does parallel assignment, supports a return value, and can properly initialize variables that don't increment.

• Improving coverage of CL by adding such forms as SETQ and PSETF.

• Improving access to JS capabilities, such as labeled for loops.

• Documentation and test case updates.

• Miscellaneous code cleanups, whitespaceification, and global

standardizations.

The changes are fully backward compatible, as long as you weren't relying on the 'broken' sequential assignment that DO and LET were doing. ;) DO* and LET* are now available for that purpose, of course.

Looks like in total I added somewhere around 350 lines and removed 210 lines from the code base, excluding documentation and test cases. To the documentation I added 368 lines and removed 227.

The changes are reasonably tested and have been in use on my production systems for a couple of months. I've included the darcs changelog below my signature.

Since I use ParenScript rather heavily, it's very likely that I'll be making more substantial changes on an ongoing basis. I'd be happy to help maintain the project. Let me know.

Cheers,

-- Travis

P.S. My branch of parenscript can currently be found here:

• Added simple-let* and aliased let* to it.

Sun Mar 30 02:22:18 UTC 2008 Travis Cross <tc@tra...>

• Added simple-let, which does parallel binding without a lambda.

Sun Mar 30 02:23:16 UTC 2008 Travis Cross <tc@tra...>

Sun Mar 30 02:33:34 UTC 2008 Travis Cross <tc@tra...>

• Updated let1-dynamic to clean up its temporary stack variable after

use.

Sun Mar 30 19:35:12 UTC 2008 Travis Cross <tc@tra...>

• Improved, extended, and refactored iteration special forms.

• Added support for DO*.

• DO now does parallel assignment.

• DO/DO* now correctly support init-forms such as:

  (do (a (b) (c 1) (d 1 (1+ d))) ...)

• DO/DO*/DOTIMES/DOLIST/DOEACH now support return values via a lambda transform.

• DOEACH now supports implicit key/value destructuring, e.g.:

  (doeach ((key val) arr res) ...)

Sun Mar 30 19:57:12 UTC 2008 Travis Cross <tc@tra...>

• Whitespaceification: removed indentation tabs throughout project.

...and replaced each tab with 8 spaces. Tab indentation had previously been used inconsistently and was dominated by space-based indentation.

In the future, disable indent-tabs-mode in emacs!
