Re: Playing music using pike and SDL.
by Martin Nilsson (lvl 60) ＠ Pike (-) developers forum 13 Mar '26

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)?

managing comport settings in linux
by Henrik Grubbstr�m (Lysator) ＠ Pike (-) developers forum 13 Mar '26

13 Mar '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.

Setting socket options: so many, uhh, options!
by Chris Angelico 10 Mar '15

10 Mar '15

Topic branch: rosuav/sockopt Per Lance's suggestion, I've made a generic setsockopt() function. It works only with integers, so it's not suitable for SO_LINGER, which therefore should stay the way it is (linger() takes a magic parameter of -1), but it works for any of the simple boolean options. As to shortcut functions, though, there are a few ways they can be done. 1) set_keepalive() always exists, even if SO_KEEPALIVE isn't available. If you call it when there's no SO_KEEPALIVE, it sets errno and returns failure. 2) set_nodelay() exists only if TCP_NODELAY is available. 3) setsockopt() itself is useless without the constants, and Stdio.TCP_NODELAY will exist only if TCP_NODELAY is available. So in a Pike script, using setsockopt() requires either has_index() run-time checks or #if compile-time checks for the options you want; set_keepalive's model works easily if you know that the Pike version you're targeting supports it; and set_nodelay's model lets you treat older Pikes and systems without that feature the same way. I'd rather make it as easy as possible on the Pike code. Which way makes more sense? ChrisA

Xenofarm seems to have been out of order since a while, correct? -- Stephen.

Proposal: Enhance Process.run() to accept functions for stdout/stderr
by Chris Angelico 03 Nov '14

03 Nov '14

I periodically find myself needing something similar to Process.run(), but processing intermediate output. Example: https://github.com/Rosuav/FrozenOST/blob/master/build.pike#L114 It needs to take whatever's sent to stderr, turn all \n into \r, and send it on to the real stdout. (Yes, it sends stderr to stdout.) I usually end up lifting the code of Process.run() and making a cut-down version (as I don't need all its features); but the obvious alternative would be to have Process.run itself provide this facility. The code is now at branch rosuav/process_run_with_func; the equivalent to my above code would be simply: Process.run(({"sox","-S","-m","-v",".5"})+tracklist/1*({"-v",".5"})+({soundtrack}), (["stderr":lambda(string data) {write(replace(data,"\n","\r"));}])); Is this a feature worth adding?

debugger opcodes
by Bill Welliver 30 Oct '14

30 Oct '14

I noticed that folks have been working on code generation lately. Any chance it might be possible to implement some of the opcodes required to get debugging working (step, break, etc)? I seem to recall someone indicating it wasn't a terribly difficult task, but it's clearly beyond my understanding of the problem. Bill

Re: Are there Sql backends that return an array from big_query()?
by H. William Welliver III 30 Oct '14

30 Oct '14

True, but the code that handles that case isn't very complex, so why create a potential compat problem? What's the benefit?
