The following is a summary of the changes in this release
|
||
|
|
from the previous one.
|
||
|
|
|
||
|
|
<h4> DrScheme </h4>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>
|
||
|
|
Non-text items (e.g. a picture) can be used in a program as a contant
|
||
|
|
value. The interaction window handles non-text for both input and
|
||
|
|
output. When non-text is used in a program saved to disk, the file is
|
||
|
|
automatically saved to disk in DrScheme's binary format.
|
||
|
|
|
||
|
|
<li>
|
||
|
|
Syntax checking has been improved, and the colors are
|
||
|
|
now parameterized through preferences.
|
||
|
|
|
||
|
|
<li>
|
||
|
|
These syntactic forms not yet supported:<tt> </tt>
|
||
|
|
do without the step form and define-structure (use define-struct instead).
|
||
|
|
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<h4> Analysis </h4>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>
|
||
|
|
The Analysis tool (MrSpidey) is temporarily unavailable in
|
||
|
|
release 44 and will reappear in a future release.
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<h4> Known Problems </h4>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>
|
||
|
|
DrScheme internally normalizes pathnames, resolving all links
|
||
|
|
to absolute paths. This causes problems with systems that use
|
||
|
|
automounting.
|
||
|
|
|
||
|
|
<li>
|
||
|
|
Even in the R4RS language level, DrSchemd does not support
|
||
|
|
case-insensitive identifiers.
|
||
|
|
|
||
|
|
<li>
|
||
|
|
The <tt>eval</tt> procedure is not supported.
|
||
|
|
</ul>
