BrianH 14-Jul-2009 [16258] | It's a global search-and-replace in the source rather than a simple assignment, but it works. |
PatrickP61 14-Jul-2009 [16259] | Thanks Brian, I had changed the APPEND2 to REPEND with the proper [ ] which seems to do the same thing as APPEND APPEND. repend blk ['label ajoin ["Field " n]] repend blk ['field form first+ fields] repend blk ['button "Change"] Thanks! |
BrianH 14-Jul-2009 [16260] | REPEND has more overhead than chained APPEND. |
PatrickP61 14-Jul-2009 [16261] | Didn't know that!!! |
BrianH 14-Jul-2009 [16262] | REPEND creates an intermediate block - it doesn't REDUCE in place like APPLY, since it is mezzanine. |
PatrickP61 14-Jul-2009 [16263] | Brian, If I wanted APPEND2 to take on the value of APPEND APPEND, how would I do that? I tried APPEND2: [append append] but it is not what I wanted. I also tried APPEND2: 'append 'append but still not right? What is the proper way to have APPEND2 take on the APPEND APPEND so that when you run DEMO, it resolves correctly? |
BrianH 14-Jul-2009 [16264] | Make a function named append2: append2: func [blk val1 val2] [append/only append/only blk :val1 :val2] |
PatrickP61 14-Jul-2009 [16265] | Oh so you first need to take a look at the append function like HELP APPEND, then define another function to pass along the same parms etc with the APPEND function in it. so then you could also say this: append2: func [blk val1 val2] [append append blk :val1 :val2] (without the /only refinement) I mean to say is that the above could also work, right? |
BrianH 14-Jul-2009 [16266] | Yes, but I think you want the /only refinement in this case. |
PatrickP61 14-Jul-2009 [16267] | got it! -- Thank you |
BrianH 14-Jul-2009 [16268] | You don't need to replicate the type spec of the arguments since this is just a helper wrapper function. |
Pekr 15-Jul-2009 [16269x2] | Can R3 be run in CGI mode? There seems to be -c command line switch, but no CGI helper functions, nor system/options/cgi path .... |
IIRC Carl posted some short notice on that, but can't find it. I would like to start testing it, e.g. the speed of page build in comparison to R2. | |
Henrik 15-Jul-2009 [16271] | Pekr: http://www.rebol.net/r3blogs/0182.html |
Pekr 15-Jul-2009 [16272x3] | Thanks, just found it too :-) |
Disappointed by outcome of latest blog. Binary conversion issues are still a catastrophe. We were supposed to get it right and easy, ok? | |
Writing a reaction ... | |
BrianH 15-Jul-2009 [16275] | Using issue! to encode binaries is a disaster. We need better conversion functions, not syntax tricks. |
Pekr 15-Jul-2009 [16276] | then issue is completly usless type - remove it |
BrianH 15-Jul-2009 [16277] | It's useful as a syntax type. We are thinking of making issue! a unique and immutable string as well, with supposed modifications generating a new issue!. It would be like words without binding or as many syntax limitations. |
Pekr 15-Jul-2009 [16278x2] | I put my reasoning into blog post ... |
hmm, Carl dismissed #1113. I wonder if 'bind is used so often, that he was afraid of overloading it, and introduced new mezzanine instead? Was that really necessary? Another one to learn ... | |
BrianH 15-Jul-2009 [16280] | Apparently he considers initializaton to be out-of-scope for BIND. Oh well, it might have been cleaner - we'll see. |
Pekr 15-Jul-2009 [16281] | BrianH: is there a bug ticket for?: >> to-issue #{0001} == #?? ... I did not understand from your blog post, if it is supposed to be fixed already, so the ticket exists, or not .... |
BrianH 16-Jul-2009 [16282] | I mistook the problem you were proposing for one that had already been fixed :) |
Pekr 16-Jul-2009 [16283x4] | yes, but is above a bug? Should be reported, no? :-) |
ah, damned, latest time related changes brought back so called RED ICONS problem once again :-) We are still not reporting timezones correctly, ignoring summer time .... | |
Ah, actually quite the reverse. The problem of R2 is gone. Summer shift time is different date each year .... R3 works correctly, R2 does not ... | |
That's cool - even a73 was broken - when you set time back to winter time, it reported wrong zone information. a74 works correctly. | |
BrianH 16-Jul-2009 [16287x3] | Pekr, the above is not a bug. Your proposed change would be the bug. The issue! type is a string type, not a binary type. |
We don't want to encourage any tendency to see issue! as a replacement for binary!, especially since issue! is a collection of Unicode codepoints internally, not bytes. The issue! type is also poor for binary conversions, due to the fact that it was designed for other things. It works well for what it was designed for, though there are proposals to make it work better for that (the unique string stuff mentioned earlier). | |
I really don't understand your attempt to make issue! be a binary conversion device. It never worked as well as binary! for that, nor is there any reason to expect that to change. Why don't you want to use well-designed binary conversion functions, rather than bad issue! tricks? The functions could even be backported to R2. | |
Pekr 16-Jul-2009 [16290x2] | Because historically I am far from being alone, who finds current R2 working as being complete mess. How can anyone defend it? I can easily tell you, where it comes from. I am far from good at wrapping libraries, but I wrapped some functionality in the end. I can often see constants like: 0x0010 Which are for me equivalent to: #0010 ; which I can get via to-hex or to-issue 16 #{0010} ; to-binary 16 = #{3136} .... and this is big WTF? Now at least R3 gets it correctly, although padded by full of zeros to form 64 bit value So, as you can see, my thought pattern came from not easy way of how to convert between integer and binary representation. I created my own crazy 2-binary function :-) to-binary*: func [value [integer!]][load rejoin ["#{" to-string copy/part at to-hex value 7 2 "}"]] |
So - stating above in regards to R2, my further thoughts went towards hex being a literal representation of binary values. But I forgot there is no hex! type, just an issue! type, which serves also other purpose. Now as to-binary 16 gives me desired value, I don't need to go via to-hex anymore ... | |
BrianH 16-Jul-2009 [16292] | Sounds good to me :) |
Pekr 16-Jul-2009 [16293] | Carl's back to security for few days - file sandboxes, IP/port masking, evaluation limits ... That sounds good too :-) |
Janko 17-Jul-2009 [16294] | didn't you say Carl will go for two week vacation? I was expecting he will not be so active for a while |
Pekr 17-Jul-2009 [16295] | Yes, he mentioned vacation in France, but dunno if he went there, or if he took his notebook with him, so he builds R3 in the evenings :-) |
RobertS 17-Jul-2009 [16296x3] | The r3 GUI demo code at r3/demo.r offers a Halt when running the test but only a Quit in the Demo launcher itself - and, at least on Windows XP, it blows out your rebol session - whereas the Halt in the demo does not. Rather annoying as a GUI demo feature ... does anyone have a moment to throw another button onto the demo launcher? |
I am trying to traverse paths that I am using at http://cl1p.net where a path might be http://cl1p.net/wp-aule///c2/Is there any way that I can use this to search for any path 3 deep such as http://cl1p.net/wp-aule/wiki/history/c2and http://cl1p.net/wp-aule/wiki/alternate/c2 and http://cl1p.net/wp-aule/smalltalk/wiki/c2??? That is, can we tolerate null in paths as, say , type unset! ?? I think of these as incomplete nestings of blocks where there happen to be unbound keys blk: [k1 [ blka ] where :blka might sometimes be [ k3 blka1 ] and sometimes just [blka1] | |
I will go back to R2 Liguid and see what these would look like as data vars whose values are not yet known. That cl1p.net tolerates these pseudo-URLs is immensly useful ... for example, we tolerate the URL fine even in R2 as in test: read http://cl1p.net/wp-aule///test and test: read http://cl1p.net/wp-aule//path42/testand http://cl1p.net/wp-aule/path21/path43/test/ | |
BrianH 17-Jul-2009 [16299x3] | I'm having a little trouble understanding your question. File/URL paths have nothing to do witth the REBOL path! type - file! and url! are string types, so they don't have inner blocks or unset! values in them. |
For url! values with multiple consecutive / characters in them, it is up to the server you are accessing to interpret them. | |
R3 file! paths ignore multiple / characters, though the CLEAN-PATH function replicates the leading multiple / fill-in-the-blanks behavior of R2 file! access, relative to a cuurrent directory. | |
RobertS 17-Jul-2009 [16302x4] | when we don't find a word in a slot, we fail; my question is COULD we tolerate an unset! where a word! is now expected ... the Rebol path! type is just too useful to ignore here ... and our use of the character '/' does have "something" to do with our natural interpretaion of file and url - files assume valid hierarchy depth at time of tracversal, a web server need not ... at the moment we have no type corresponding to what follows an HTTP schema and domain other than string .... or am I mistaken? |
perhaps if someone knows an OS where the user (without recourse to a custom GLOB script) can search for any file, say cfg.txt at "depth 5 " ,e.g., | |
/home////cfg.txt as finding /home/local/bin/scripts.cfg.txt and /home/lib/ruby/site/rules/cfg.txt | |
Of course at the moment in current r3, test: read http://cl1p.net/wp-aule///test pitches back with binary ;-) | |
BrianH 17-Jul-2009 [16306x2] | The problem is that an http server has the option to provite a directory of their resources, but there is no generally agreed-on machine readable format for providing such a directory, and the human readable format (a Site Map), isn't implemented on most sites. If the site you are interested in has a site map you can grab and parse that, or you can trace throuugh the links on the site and hope for the best, or you can make use of an external service like Google that has already traced through the links. |
Most sites that do provide a site map only include a brief overview of their resources, not a comprehensive directory. | |
