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?

[Patch] pike -x
by bertrand.lupart＠linkeo.com 28 Mar '08

28 Mar '08

Hello, Here's a patch for having a more clear error message and abort if the specs file isn't present at the expected location when running "pike -x monger --install" for example. The current error is actually a user-unfriendly backtrace. Maybe the check for this file could be moved elsewhere, since before checking for the specs file, monger select the good version of the software to install and downloads it. ----8<----8<----8<----8<---- --- Tools.pmod/Standalone.pmod/module.pike.ori 2008-03-18 15:32:11.000000000 +0100 +++ Tools.pmod/Standalone.pmod/module.pike 2008-03-18 15:50:42.000000000 +0100 @@ -194,6 +194,14 @@ int main(int argc, array(string) argv) { + string specspath=include_path+"/specs"; + + if(!Stdio.is_file(specspath)) + { + werror("Missing specs file at %s\n",specspath); + return 1; + } + run_pike = master()->_pike_file_name; #ifdef NOT_INSTALLED run_pike += " -DNOT_INSTALLED"; @@ -205,7 +213,7 @@ run_pike += " -m"+master()->_master_file_name; putenv("RUNPIKE", run_pike); - load_specs(include_path+"/specs"); + load_specs(specspath); foreach(Getopt.find_all_options(argv,aggregate( ({"autoconf",Getopt.NO_ARG,({"--autoconf"}) }), ---->8---->8---->8---->8---- -- Bertrand LUPART http://bertrand.gotpike.org/

Compiler/interpreter feature request
by cschalkwijk 27 Mar '08

27 Mar '08

I don't know if it's already available (if so: I'd like to know) but I'd like to receive warnings about unused variables/objects/methods in Pike. Is this possible? Next to that: is there any progress with the Pike Eclipse plugin? (What was the url again?)

libffi and java-static elements
by H. William Welliver III 25 Mar '08

25 Mar '08

Did I understand correctly that libffi will be a bundle in Pike 7.8? If so, that makes it easier for me to include the Objective-C module directly in Pike. Also, I vaguely recall some additions to 7.7 that seemed to suggest java-static elements were coming at some point, too. Did I misunderstand that? If I didn't what is the current status? Right now, the Objective-C makes (inappropriate) use of function constants to make "class" methods appear in classes. Bill

There was some checkins to support it, but nothing besides that yet.

Difference in execution speed
by cschalkwijk 25 Mar '08

25 Mar '08

I was wondering, which is faster (in Pike) or are they eventually the same? if(search(someArray, someElt) < 0){;} or if(search(someArray, someElt) == -1){;} If one is faster, why?

rot13
by Martin Nilsson (Opera Mini - AFK!) ＠ Pike (-) developers forum 24 Mar '08

Appearently Crypto.Substitution()->set_rot_key(13)->encrypt(x) was too difficult to find so eMBee added String.rot13(), though 17 times slower. I obviously has an opinion as Crypto co-author, but I think it is reasonable to have ROT13 in the Crypto module instead of String.

Filenames in the Pike CVS repository are now valid UTF-8
by Henrik Grubbstr�m (Lysator) ＠ Pike (-) developers forum 19 Mar '08

19 Mar '08

FYI: I doubt that anyone will notice (or care :-)), but I've just renamed the few files in Pike that contained 8-bit characters, so that they may be stored on filesystems that enforce UTF-8 encoding (eg HFS or ZFS). The only files affected were the (deleted) file src/modules/image/doc/säljstöd.html in Pike 0.5, 0.6, 7.0, 7.2 and 7.4, and the external pike-module µpgp/µpgp.pike.
