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)?

managing comport settings in linux
by Henrik Grubbstr�m (Lysator) ＠ Pike (-) developers forum 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.

Pike 8.0.528 release candidate
by Peter Bortas 11 May '18

11 May '18

As is tradition a release has been prepared at the new years party with Champagne in one hand and keyboard in the other waiting for the clock to hit 24:00. Pike 8.0.528 release candidate: https://pike.lysator.liu.se/pub/pike/beta/8.0.528/Pike-v8.0.528.tar.gz Other builds: https://pike.lysator.liu.se/pub/pike/beta/8.0.528/Pike-v8.0.528-Darwin-15.4… https://pike.lysator.liu.se/pub/pike/beta/8.0.528/Pike-v8.0.528-win32-oldli… Real Mac build comes when Bill has time to have a look at that. Changes since Pike 8.0.498 (release 11) ---------------------------------------------------------------------- New Features ------------ o Sql.pgsql - Added support for PostgreSQL 10's stronger password authentication (SCRAM-SHA-256). - Slightly reduced overhead. - Support IEEE binary float database-wireformat. - Prevent new queries from starting in the local_backend. o Crypto.Hash.SCRAM New class to support SCRAM authentication. o Thread.ResourceCount New module to allow threadsafe race-condition-free counting of resources. o SSL.File Support query_fd() and set_buffer_mode() methods. o Toole.Standalone.check_http - Allow redirect responses. - Support --expect option. Bug fixes --------- o Compiler Improved variant robustness. o Calendar Updated tzdata to 2017c. o Crypto.CCM Fixed initialization of the iv. o Filesystem.Monitor - Fixed issue with next_poll being set to zero causing polling every second. - Fixed indexing the NULL value error when InotifyMonitor was used in combination with a filter_file() that doesn't accept everything. o HTTPLoop: Fixed some potential race conditions. o Image.Image - Improved argument checking in apply_curve(). Non-integer array values lead to use of uninitialized curve values. o Image.PVR Fixed size check for twiddled images. o MIME Support trailing newline in MIME part epilogues. o Protocols.HTTP Fixed incoming chunked transfers (timed async works now, chunk options are properly 'parsed'). o Protocols.LDAP Fixed race condition on initializing LDAPS. o Search.Utils Updated debug string format. o Sql.pgsql - Suppress spurious 'File not open' blurts on stderr when the connection is still pending and we inspect the connection object. - Signal EOF early before closing the SQL result portal and thoroughly cleanup bufcon/stashcount to prevent occasional deadlocks on asynchronous object destructions. - Suppress rare "access in destructed object" messages. - Rip out fundamentally flawed reconnect logic, made failures consistent. - Repair SSL connect logic. - Update documentation. - Repair fetch_row_array(). o mktime/System.TM Make timezone management consistent (especially UTC handling). o Standards.IIM Disabled debug output for unknown segment markers. o Stdio.send_file Improved support for TLS/SSL; wait for TLS handshake to complete before calling the sendfile done callback when sending an empty string. This fixes the issue where the connection got closed before TLS handshaking was completed, confusing the other side. o Image Creating images with mode "grey" now works as documented, e.g. Image.Image(10,10,"grey",123); Optimizations ------------- o mktime/System.TM Considerable speedup and a reduction in codesize. Building & Tools ---------------- o Image.SVG Fall back to using the unprefixed pkg-config if the arch-prefixed doesn't exist. o Mysql Support MariaDB 10.2 headerfiles. o precompile Support precompilation with Pike 8.1 again. o smartlink Fixed multiple issues on Darwin & NetBSD. o Whitefish Use the standard VPATH. o Yp Support using libtirpc. Glibc 2.26 has removed the Sun RPC implementation... Regards, -- Peter Bortas

strange error on cross-compiled pike 8
by H. William Welliver III 02 Feb '18

02 Feb '18

I cross compiled pike 8.0.498 on an amd64/linux system for use on an armv5tejl/linux system, and I’m getting a strange error when starting it up: -:1: Type mismatch for callback function `[]=: -:1: Expected: scope(0,function(zero, (0=zero) : 0)). -:1: Got : function(int(128..-129), int(128..-129) : int(0..-16777216)). -:1: Program constant "Buffer" is NULL. program.c:6011: Fatal error: Failed to initialize class '_Stdio' No stack - no backtrace. Aborted At first I thought it might be a dynamic loading problem, but _Stdio shouldn’t be a dynamic module, right? Anything obvious I might be missing?

Newlines in strings
by Stephen R. van den Berg 29 Jan '18

29 Jan '18

When writing some new SQL queries, I was wondering, would there be a downside to allowing direct newlines in strings? I.e. sample code: mixed r = db->big_typed_query(" SELECT invno FROM mutation mu WHERE mu.mutid = 12 "); would then just work. And if that is not desirable, any other suggestions which do not involve ugliness like: mixed r = db->big_typed_query("" "SELECT invno " " FROM mutation mu " " WHERE mu.mutid = 12 " ""); or mixed r = db->big_typed_query(" \ SELECT invno \ FROM mutation mu \ WHERE mu.mutid = 12 \ "); -- Stephen.

GTK2 setting locale
by Arne Goedeke 29 Jan '18

29 Jan '18

The GTK2 module sets the locale of the process to "". This breaks on locales which e.g. use COMMA instead of PERIOD for floating point numbers. The symptom I have observed is that pike will run into a loop inside of the compiler when trying to parse a float and then eventually crash. I think the short-term fix should be to call gtk_disable_setlocale() inside of the GTK2 module to prevent GTK2 to change the locale. Maybe mid-term we can make pike not depend on the process locale? I suppose there might be other external modules which might mess with locale. Arne P.S. I won't be able to attend the pike meetup unfortunately...

Hi again, i have a gui code here. The button is half size of the main window and to great. Any idea how to make it smaller ? _____________________________________________________ GTK2.Widget mainwindow,clickcnt,clicker; int clicks; void click() { clickcnt->set_text("Clicks: "+(++clicks)); } int main() { GTK2.setup_gtk(); mainwindow=GTK2.Window(GTK2.WindowToplevel); mainwindow->set_title("Click counter"); mainwindow->set_size_request(600, 500); mainwindow->set_position(GTK2.WIN_POS_CENTER); mainwindow->add(GTK2.Vbox(0,10) ->add(clickcnt=GTK2.Label("There have been no clicks yet")) ->add(clicker=GTK2.Button("Click me")) )->show_all(); mainwindow->signal_connect("delete_event",lambda() {exit(0);}); clicker->signal_connect("clicked",click); return -1; } -- Sent from: http://pike.1058338.n5.nabble.com/Pike-Dev-f4605220.html

Set a gtk2 window to center in pike 7.8

//How to set the positon of window1 to center ?// window1->set_position(GTK2_WINDOW(window), GTK2_WIN_POS_CENTER_ALWAYS); //window1 is a toplevelWindow// object window1 = GTK2.Window(GTK2.WINDOW_TOPLEVEL); Let us assume not to be programmer. Instead a metalworker. I only want to cut out a metal sheet as main in the right size and center position!
