# RETRO 2020.4
|
|
|
|
This release fixes a couple of bugs, and makes a lot of improvements
|
|
to the standard library, using inline assembly to enhance performance
|
|
and reduce size.
|
|
|
|
A few of the larger changes:
|
|
|
|
- bug fixes
|
|
|
|
- removed an incorrect header stub from rx.muri
|
|
|
|
- fixed bug in s:index-of-string
|
|
|
|
- improvements
|
|
|
|
- lots of size reductions
|
|
|
|
- increased use of hand packed assembly in the stdlib
|
|
|
|
- removed numerous variables
|
|
|
|
- faster performance in rewritten words in the stdlib
|
|
|
|
- remove deprecated words
|
|
|
|
- as{ }as " prefix:"
|
|
|
|
- examplse
|
|
|
|
- markdown.retro
|
|
|
|
- future
|
|
|
|
underscores in word names
|
|
|
|
Prior RETRO images had a patch that allowed underscores to be
|
|
used in word names. In this release, the patch is no longer
|
|
part of the standard library, but is still included on Unix
|
|
targets by default. This might affect some users, if you are
|
|
building a custom image, load package/allow-underscores-in-names.forth
|
|
if you need this. This will no longer be loaded by default after
|
|
the 2020.4 release.
|
|
|
|
modularity
|
|
|
|
Work towards allowing portions of the standard library to be
|
|
optional is ongoing. During this, the internal organization of
|
|
retro.forth is changing and some small parts may be duplicated
|
|
in an effort to allow for more flexibility in the long term.
