Sequences:
|
|
|
|
|
<ul>
|
|
|
|
|
<li>The following formely list-specific words are now generic:
|
|
|
|
|
|
|
|
|
|
<pre>all? ( seq quot -- ? | quot: elt -- ? )
|
|
|
|
|
all-with? ( obj seq quot -- ? | quot: elt -- ? )
|
|
|
|
|
subset ( seq quot -- seq | quot: elt -- ? )
|
|
|
|
|
subset-with ( obj seq quot -- seq | quot: obj elt -- ? )
|
|
|
|
|
fiber? ( seq quot -- ? | quot: elt elt -- ? )
|
|
|
|
|
prune ( seq -- seq )</pre>
|
|
|
|
|
|
|
|
|
|
<li> The <code>contains?</code> word for testing membership in a sequence has been
|
|
|
|
|
renamed to <code>member? ( elt seq -- ? )</code>.
|
|
|
|
|
|
|
|
|
|
<li> The list-specific <code>some?</code> and <code>some-with?</code> combinators are gone. Their replacements are generic:
|
|
|
|
|
|
|
|
|
|
<pre>contains? ( seq quot -- ? | quot: elt -- ? )
|
|
|
|
|
contains-with? ( obj seq quot -- ? | quot: obj elt -- ? )
|
|
|
|
|
find ( seq quot -- i elt | quot: elt -- ? )
|
|
|
|
|
find* ( i seq quot -- i elt | quot: elt -- ? )
|
|
|
|
|
find-with ( obj seq quot -- i elt | quot: elt -- ? )
|
|
|
|
|
find-with* ( obj i seq quot -- i elt | quot: elt -- ? )</pre>
|
|
|
|
|
|
|
|
|
|
See the developer's handbook for details.
|
|
|
|
|
|
|
|
|
|
<li> The <code>nreverse ( seq -- )</code> word has been removed.
|
|
|
|
|
|
|
|
|
|
<li> <code>reverse-slice ( seq -- seq )</code> outputs a new sequence that shares
|
|
|
|
|
structure with the given sequence, but presents elements in reverse
|
|
|
|
|
order.
|
|
|
|
|
|
|
|
|
|
<li> The <code>string-compare</code> primitive has been replaced with the lexi word
|
|
|
|
|
which now operates on any pair of sequences of numbers. The
|
2005-07-22 22:18:47 -04:00
|
|
|
string> word has been replaced with <code>lexi></code>.
|
2005-07-21 21:43:37 -04:00
|
|
|
|
|
|
|
|
<li> The <code>,</code> word no longer accepts a string as input inside a <code>make-string</code>. In 0.75, the following
|
|
|
|
|
two lines were equivalent:
|
|
|
|
|
|
|
|
|
|
<pre>[ "Hello" , " world" , ] make-string
|
|
|
|
|
[ "Hello" % " world" % ] make-string</pre>
|
|
|
|
|
|
|
|
|
|
<li> Now, the former raises a type error. Use <code>,</code> with characters, and <code>%</code> with
|
|
|
|
|
strings inside make-string.
|
|
|
|
|
</ul>
|
|
|
|
|
|
|
|
|
|
<li>Streams:
|
|
|
|
|
|
|
|
|
|
<ul>
|
|
|
|
|
<li>The following words have been renamed:
|
|
|
|
|
|
|
|
|
|
<pre>stream-auto-flush ==> stream-finish ( stream -- )
|
|
|
|
|
stream-write-attr ==> stream-format ( string style stream -- )
|
|
|
|
|
write-attr ==> format ( string style -- )</pre>
|
|
|
|
|
|
|
|
|
|
<li>The following words no longer accept character arguments:
|
|
|
|
|
|
|
|
|
|
<pre>stream-format ( string style stream -- )
|
|
|
|
|
format ( string style -- )
|
|
|
|
|
stream-write ( string stream -- )
|
|
|
|
|
write ( string -- )
|
|
|
|
|
stream-print ( string -- )
|
|
|
|
|
print ( string -- )</pre>
|
|
|
|
|
|
|
|
|
|
<li>Use the new words to write characters:
|
|
|
|
|
|
|
|
|
|
<pre>stream-write1 ( char stream -- )
|
|
|
|
|
write1 ( char -- )</pre>
|
|
|
|
|
|
|
|
|
|
Note that <code>stream-write1</code> is generic and your stream must implement it.
|
|
|
|
|
|
|
|
|
|
<li><code>with-string</code> word renamed to <code>string-out ( quot -- string )</code>
|
|
|
|
|
|
|
|
|
|
<li>New <code>string-in ( string quot -- )</code> word, calls <code>quot</code> with <code>stdio</code> bound to
|
|
|
|
|
a stream that reads from the given string.
|
|
|
|
|
</ul>
|
|
|
|
|
|

|
|
|
<li>Everything else:
|
|
|
|
|
|
|
|
|
|
<ul>
|
|
|
|
|
|
2005-07-21 21:43:37 -04:00
|
|
|
<li>Many improvements to the matrices library.
|
|
|
|
|
|
|
|
|
|
<li>Improved inspector. Call it with <code>inspect ( obj -- )</code>.
|
|
|
|
|
|
|
|
|
|
<li>The number of generations used for garbage collection can now be set
|
|
|
|
|
with the +G command line switch. You must specify at least 2
|
|
|
|
|
generations.
|
|
|
|
|
|
|
|
|
|
<li>Only 2 generations are used by default now, since there seems to be no
|
|
|
|
|
performance benefit to having 3 after running some brief benchmarks.
|
|
|
|
|
|
|
|
|
|
<li>Fixed bug where images saved from the jEdit plugin would fail to
|
|
|
|
|
start.
|
|
|
|
|
|
|
|
|
|
<li>md5 hashing algorithm in <code>contrib/crypto/</code> (Doug Coleman).
