negative indices in array ranges
by Martin Baehr 14 Aug '26

14 Aug '26

hi, instead of having to do: reverse(reverse(foo/"/")[1..]); i'd very much prefer: (foo/"/")[..-2]; are there any reasons that speak against supporting this other than me not being able to offer a patch? greetings, martin.

levels might possibly be from -1 and up, -1 meaning infinite.

managing comport settings in linux
by Henrik Grubbstr�m (Lysator) ＠ Pike (-) developers forum 09 Apr '26

Not a good idea; the design philosophy of Pike is that Pike-level code should never be able to cause memory corruption at C-level. With ioctls there's no way to know what data a specific ioctl wants without reading the documentation for that specific ioctl for that specific OS. ioctls and fcntls are a way for device handlers to hook in APIs that aren't standard across all filedescriptors. / Henrik Grubbström (Lysator) Previous text: >2004-08-17 13:32: >Subject: managing comport settings in linux >-------------------------------------------------------------------- >What would be nice, is a way to define ioctl methods in >Pike.

Re: Playing music using pike and SDL.

Were you not able to get any C code to play through SDL either? Does your SDL library have a mixer compiled in it (I think it is optional)?

Process.run
by Peter Bortas (nu med mindre Opera) ＠ Pike (-) developers forum 15 Jul '08

15 Jul '08

I just checked in a Process.run() in 7.7: http://pike.ida.liu.se/development/cvs/diff.xml?module=Pike&file=7.7/lib/mo… The rational for that is that I was once again reminded by a user this week that getting Process.create_process() or Process.Process right without some corner case blocking is hard. It's not obvious that if you bind pipes to booth stderr and stdout you have to take in to account that OS buffers are not limetless. Process.run() is a thin wrapper around Process.Process that collects stdout, stderr and exitcode and return them in a mapping. This could potentially result in huge strings, but will do what most users want and even already do when they call create_process() with both pipes bound. Something like this should be in 7.8, but I'm open to suggestions for other things that might be usefull to return in the mapping or for changing member names.

7.8 blockers
by Peter Bortas ＠ Pike developers forum 17 May '08

17 May '08

Me, grubba an Nilsson enumerated the major 7.8 blockers yesterday. They are as far as we could determine: [ ] not done [/] tentatively fixed [X] fixed Owner Issue [ ] grubba Deprecated type should print warnings. [ ] grubba Implement #pragma to turn off deprecated warnings. [ ] zino Known crash on Windows. [ ] mast/zino New Windows build environment. [ ] per/marcus Performance regression --with-assembler. (per and marcus weren't present so item assigned without consent... per says memprotect() is responsible as far as -x benchmark goes.) [ ] nilsson Running the test suite should not produce warnings. [ ] zino/mast Building external modules should work. [ ] nilsson Write ChangeLog. [ ] Deprecated type should be extracted to documentation. [ ] Documentation should transform from XML to HTML (broken) [ ] nilsson Arg module should be fixed or removed. Non-blockers: [ ] jhs Build (SVG) graph from the -x benchmark results Pikefarm delivers to track development. If you think you could help with any of the items please do. Especially the items that have no one assigned to them yet.

Very strange string literal problems
by cschalkwijk 06 May '08

06 May '08

(["connect_options":2]) When I tried adding the above mapping to my code. Roxen started, but remains unreachable via a webbrowser. But, and this is the strange part, when I change the string literal from "connect_options" to for example "variable", Roxen starts and is available. Isn't this strange?! I know this is the exact cause for the change to occur, since it is truly the only thing that was changes. Oh, I forgot to mention that I'm NOT EVEN USING the mapping :) . The error/strange behaviour purely results from creating the mapping: catch { mapping(string:int) tst_opt = (["connect_options":2]); dbconn = Sql.Sql( QUERY(db_string)); }; I didn't get to the part of actually using the mapping yet. __________________________________________________________ Deze e-mail en de inhoud is vertrouwelijk en uitsluitend bestemd voor de geadresseerde(n).

Spear !
by PeterPan 06 May '08

06 May '08

Hi! Pike team. I hooked Pike's compile_string() and compile_file(), and got a "new" language. I named it "Spear". In Spear, you can embed C code in Pike, and reference the variables each other. see the example: $ cat hello.spear #! /usr/bin/env spear void main() { C.INCLUDE("#include <stdio.h>"); C.CC("gcc -shared -fPIC"); string s="pike"; int n=2008; float pi=3.1415926535; C{ char* str="c string"; int m=514; double e=1.41421; printf("hello world!\n"); printf("printf %s string\n",STRING{s}); printf("printf pike int: %d\n",INT{n}); printf("printf pike float: %f\n",FLOAT{pi}); P{s="modify";} printf("%s pike var\n",STRING{s}); P{write("write %s\n",STRING{str});} P{write("write c int: %d\n",INT{m});} P{write("write c float: %f\n",FLOAT{e});} } } $ pike -x spear hello.spear hello world! printf pike string printf pike int: 2008 printf pike float: 3.141593 modify pike var write c string write c int: 514 write c float: 1.414 How to install: Extract the attachment in Pike-v7.7-snapshot and make. Please see the README-spear: $ cat README-spear Install: tar xzvf snapshot.tar.gz cd Pike-v7.7-snapshot tar xzvf ../Pike-Spear-vN.N.NNNNNNNNN.tar.gz Note: * src/Makefile.in is base on Pike-v7.7.44-20080421, do a vimdiff before use with a diffrent version of Pike.

Well, yes, that _is_ weird. :-)
