Anton 9-May-2005 [451x4] | (DO first tries to LOAD the decompressed string.) |
The decompressed string was identical to the original string. The compression/decompression has nothing to do with it. The problem is in loading a string of code copied straight from an editor or somewhere. If that code had been MOLDed first it would have been OK. >> mold #"^M" == {#"^^M"} ;<--------- note the double escape, this string loads properly. | |
I think rebol doesn't load #"^M" and #"^J" because they are CR (ascii 13) and LF (ascii 10). In rebol, these are molded to #"^M" and #"^/"..... | |
.... mmm that may explain LF because it has an alternate representation #"^/", which is by default molded by rebol, but that doesn't explain #"^M"... Anyway, it seems to be a bug. I vaguely remember it was found before. | |
BrianH 9-May-2005 [455x2] | ^M and ^J are newline characters. The syntax of REBOL doesn't allow direct newline characters in strings surrounded by " characters. In the example you use, the string is read twice - first in the console, and then next in the load. Each time the string is read it is unescaped (the effects of the ^ char is applied). Since you are unescaping twice, you need two ^ characters, the first to escape the second. |
Not an error, sorry. | |
Gabriele 9-May-2005 [457] | yesp, it's not a bug as Brian says. |
Izkata 9-May-2005 [458] | Just an unusual handling because of the way I copy/pasted it.. |
BrianH 9-May-2005 [459] | If you are using /View, try reading from clipboard:// rather than pasting - no escaping will happen then. |
Anton 10-May-2005 [460] | ^M and ^J (in causing the load error) are exceptional in the alphabet of A - Z. For example: >> load {#"^A"} == #"^A" None of the rest require double-escaping. I am trying to think of the reason why rebol treats the newline characters differently. |
Gabriele 10-May-2005 [461x8] | anton: that's not a suprise |
>> {#"^A"} == {#"^A"} >> {#"^/"} == {#" } | |
see the difference? | |
the closing " is on a different line. that causes an error. | |
see also: | |
>> load {#"^""} ** Syntax Error: Invalid string -- " ** Near: (line 1) #""" | |
anothe way to look at it is to look at the binary representation: | |
>> as-binary {#"^A"} == #{23220122} >> as-binary {#"^/"} == #{23220A22} | |
Volker 10-May-2005 [469] | {#"^/"} - then char-molding is buggy? |
Gabriele 10-May-2005 [470x7] | is it? |
>> mold newline == {#"^^/"} | |
i really don't think so :) | |
Peter: about your ticket -211 about GET... GET has nothing to do with that :) | |
>> print :source ?function? | |
that's the difference between FORM and MOLD: | |
>> form :source == "?function?" >> mold :source == {func [ "Prints the source code for a word." 'word [word!] ][ prin join word ": " if not value? word [print "u... | |
Volker 10-May-2005 [477] | oh, misreaded your {#"^/"}. thare are string-parens around.. you are right :) |
Gabriele 11-May-2005 [478x2] | what do you think about http://www.rebol.net/cgi-bin/rambo.r?id=3363& |
a number of bugs have been fixed. please check out the "Waiting for testing" tickets to see if you favorite bug has been fixed, so that you can test it and we can switch to tested. :) | |
Volker 11-May-2005 [480x3] | 3130 Bug: On Linux, CALL interferes with TCP port wakeup, 3159 Bug: Linux: system port interferes with TCP ports using it for some hours to do remote calls thru tcp, works. did not work with older rebol. IMO fixed. |
3326 Bug: CALL should accept file! datatype does it now (linux) | |
3576 Bug: browse doesnt open web browser (Linux) and 3455 are the same. | |
Graham 11-May-2005 [483] | Is there a way to see only the rambo entries one has made ? I am "guest" and hope no body else was guest ! |
Gabriele 12-May-2005 [484] | graham: i don't think you can search by submitter currently. |
Graham 12-May-2005 [485] | Pity .. I was wondering what the status of my submissions was. |
Anton 12-May-2005 [486x3] | Bug #3099: looks much better although I noticed this: >> to-integer -2147483648.0 ** Math Error: Math or number overflow ** Where: to-integer ** Near: to integer! :value |
Bug #3403 Looks good to me on View 1.2.103 | |
Bug #3436 looks good and solid by View 1.2.102 | |
shadwolf 13-May-2005 [489x3] | don't know if it's really a bug ... |
>> greater-or-equal? 1.2.48.3.1 system/version == false >> system/version == 1.2.102.3.1 >> | |
if it's a bug it could be cool to patch it too ... | |
DideC 13-May-2005 [492x2] | >> help greater-or-equal? USAGE: GREATER-OR-EQUAL? value1 value2 DESCRIPTION: Returns TRUE if the first value is greater than or equal to the second value. GREATER-OR-EQUAL? is an action value. ARGUMENTS: value1 -- (Type: any) value2 -- (Type: any) |
So you have to invert arguments : greater-or-equal? system/version 1.2.48.3.1 | |
Ladislav 13-May-2005 [494] | RE #3099: >> to integer! #{80000000} == -2147483648 >> - to integer! #{80000000} == -2147483648 |
Gabriele 13-May-2005 [495x2] | about: http://www.rebol.net/cgi-bin/rambo.r?id=3363&do you think FIND should stay as it is for compatibility? or it's better to change it? |
Carl: "On negate bug: looks like a C compiler problem. I may be able to fix that with an explicit check for that value, but it will slow down the function by a lot. Is that worth it?" | |
Volker 13-May-2005 [497x3] | what is that negate-bug? Ladislavs example? thats an overflow. 0 is "positive", so there is one negative number more. and negative numbers count downward, all bits on is highest possible. the conversion is: invert all bits, add 1. gives #{7FF..}, + 1 #{800..} |
find - hmm. till 'as-string it was handy with big data. now we can rewrite it, but detecting that use is tricky. but its surely a surprise. maybe we can forbid find without /case for a while with binary? gibing some usefull warning. | |
i have a wish: integrating 'comment in some more dialects. parse, layout come to mind. could then be used for embedded documentation. what do you think? | |
BrianH 13-May-2005 [500] | I second the request for comment! |
