managing comport settings in linux
by Henrik Grubbstr�m (Lysator) ＠ Pike (-) developers forum 10 Apr '26

10 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.

Getopt mark II
by Martin Nilsson (Opera Mini - AFK!) ＠ Pike (-) developers forum 19 Apr '08

19 Apr '08

(or rather Getopt mark III, since I've already rewritten the current one, although no functionality was changed then) I've been working a bit on a new Argument parser, and would like some input. In reality there will be two different way of using the argument parser, which really doesn't share any code but is convenient to do at the same time. The first one is a "I just want to get this over with" kind of interface: void main(int num, array argv) { mapping args = Arg.parse(argv); argv = args[Arg.REST]; } The output will contain ([ "foo":1 ]) if the argument is --foo and ([ "foo":"bar" ]) if the argument is --foo=bar. There is no fancy stuff to handle default values (just or it with another mapping) or options that may or may not have values (e.g. -bar=foo will produce ([ "b":1, "a":1, "r":"foo" ]) and --foo x --bar will just produce ([ "foo":1 ]) and then stop processing the line). The other mode is the (supposedly) easy yet powerful mode that you would use for more mature applications. class Parser { inherit Arg.Options; Arg verbose = NoArg("-v")|NoArg("--verbose")|Env("VERBOSE"); Arg level = HasArg("-l")|HasArg("--level"); } void main(int n, array argv) { Parser p = Parser(argv); // Index magic. Some like it, some not so much. if( p->verbose ) werror("Level %s\n", p->level); } Which is extended in class Parser { // The name for now. inherit Arg.OptionsSupreme; Arg verbose = NoArg("-v")|NoArg("--verbose")|Env("VERBOSE"); // These are used in the automatically generated --help response. string help_pre = "This program is like awesum."; string verbose_help = "Increases the verbosity of the program."; // Called when/if verbose is set to a value. void verbose_cb(string arg) { werror("Verbosity is on.\n"); } } Does this match the long list of requirements that I've heard from others?

pike-svn repo import into git
by Martin Bähr 23 Feb '08

23 Feb '08

hi, importing the pike-svn repo into git took 3 days. git-svn seems to have some issues there, as the process got slower and slower (and in the end git-svn had more than 300MB in ram (allocated 1GB)) the resulting repo had 178645 objects and a size of 1178MB. git-svn allocates another 1.5GB for statusinformation on each branch. (and because tags are branches, the 1729 tags result in as many branches) however, after packing, the resulting repo ocupies a mere 44MB!!! that alone is a good reason for me to use git, as it it gives me the whole repo in the same space as the checkout of a single revision in svn. you can clone this repo from http://www.iaeste.at/~mbaehr/pike-svn.git the svn import info is removed from that repo. when we switch to svn i'll try to make a repo available that contains the svn info to spare anyone else who wants ot use git-svn a 3day import. greetings, martin.

debian package of pike (and caudium)
by Henrik Andreasson 23 Feb '08

23 Feb '08

Hi! How is it going with the debian packages of pike, anything I can to to help? The package is still owned by debian-qa-team maybe a new version that adopts the package would be good? Shamless request: I'm going to take over the caudium package but I'm not yet a debian developer so maybe somebody on the list could help me in the beginning with the uploads? //Henrik Andreasson "kinneh"

7.6 release plans?
by H. William Welliver III 07 Jan '08

07 Jan '08

Hi All, I was wondering if there were any plans to do a new 7.6 release in the near future. There's a bug that's critical for me in the .112 Mysql module that causes a segfault, that's been fixed in 7.6 CVS. Because of this, I was thinking about holding off on a release on my end if a new pike version was looming on the horizon. If not, that's okay, too, I can try to come up with a workaround. Bill

Assumed .pike
by Martin Nilsson (Opera Mini - AFK!) ＠ Pike (-) developers forum 29 Dec '07

29 Dec '07

If .pike is omitted when declaring a script to run, Pike will add this automatically. It will however not update the argv array. Is this the behaviour you would expect? Example. foo.pike: void main(int n, array args) { write("%O\n", args); } $ pike foo bar ({ /* 2 elements */ "/home/nilsson/foo", "bar" })

pcre bundled with pike 7.8
by H. William Welliver III 21 Dec '07

I'm not sure if this was discussed previously, but would there be any possibility of bundling pcre with pike 7.8, or at least compiling with it on windows? Just wondering... bill
