Protocols.TELNET.Readline
by Martin Baehr 06 Jan '03

06 Jan '03

hi, can someone make up for the lack of documentation and explain how to use Protocols.TELNET.Readline? i have extracted some ideas from the roxen hilfe protocol implementation and condensed it to the example below. the main thing i am wondering about is this init loop, it does not seem to work without. #!/usr/bin/pike object readln; void got_connection (mixed port) { object in; if(port) in=port->accept(); if (!in) { werror("Couldn't accept connection"); return; } werror("port is open\n"); readln = Protocols.TELNET.Readline(in, got_user_line, 0, 0, 0); init(); } int n; static void init( ) { if( readln->readline ) { readln->readline->write("Welcome\n", 1); return; } n++; if( n < 100 ) call_out( init, 0.1 ); else { readln->message("Failed to set up terminal.\n"); } } void got_user_line( mixed q, string line ) { readln->readline->write("> "); write("input: %O, %s\n", q, line); } int main() { object port=Stdio.Port(); port->bind(3333,got_connection,"localhost"); port->set_id(port); return -1; }

encode_value for objects
by David Hedbor ＠ Pike developers forum 06 Jan '03

06 Jan '03

Hmm. Isn't it enough to provide an _encode and _decode method to allow objects to be en/decoded? I get this: Cannot encode objects without an "encode_object" function in the codec. pgallery.pike:24: pgallery()->main(1,({"/home/neotron/src/pgallery/pgallery.pike"})) The documentation states that the Codec in the master will be used if none is provided - well, it has: mixed encode_object(object x) { if(x->_encode) return x->_encode(); error("Cannot encode objects yet.\n"); } Am I missing something? Hmm. Ok, so it DOESN'T use the default codec in the master it seems. It works with: encode_value(o, master()->Codec()); Documentation error, bug or something that is new in Pike 7.5?

Problem with `modifier { ... }'
by rjb ＠ Pike developers forum 06 Jan '03

Hello, This script fails: #!/usr/bin/pike7.2 static { object cache = class{ mapping env; }(); } void create() { cache->env = getenv(); } int main() { write( (string)sizeof(cache->env)+"\n" ); return 0; } => No such variable (env) in object. bug.pike:8: create() With plain `static object cache = ...' it works as expected. I'm not able to check right now whether this bug (?) is still present in 7.4, sorry... /rjb

FTP?
by David Hedbor ＠ Pike developers forum 06 Jan '03

06 Jan '03

Has anyone worked on an FTP (client) protocol module at all? My current project wouldn't mind having one (although it could of course also use an external ftp application). For those interested, I'm working on a photo gallery application. I.e GTK application which allows you to build a nice photoalbum (with "infinite" number of sub-albums etc, image cropping, scaling and such) which gets generated to HTML (or RXML, PHP or whatever) using a couple of predefined or custom templates.

The xenofarm target (pedantic) still doesn't work though. Suggestions for flags to add to the target to ease debugging?

depend
by Mirar ＠ Pike developers forum 05 Jan '03

> depend: $(SRC_TARGETS) $(TPIKE_TARGETS) Should a pike really have to be built to generate the dependencies needed for building the pike that is needed to generate the dep...?

depend
by Mirar ＠ Pike developers forum 05 Jan '03

05 Jan '03

I ask because "make" doesn't work for me since my dependencies are broken, and "make depend" tries to build a pike and fails because my dependencies are broken. It would have worked if "make clean" cleared the dependencies files, but it doesn't.

stdin->line_iterator
by Martin Nilsson (bygger parser ＠ Pike (-) developers forum 05 Jan '03

05 Jan '03

I've discovered a little annoyance with the line iterator. If I have a file with the contents "a\nb\n" and runs cat test | pike -e "foreach(Stdio.stdin->line_iterator();; string x) write(x);" I get the output ab but if I run the same code with the file content "a\nb" I get a as output. Is it a bug or just a misfeature?

GTK questions
by David Hedbor ＠ Pike developers forum 05 Jan '03

05 Jan '03

So I'm designing a new app using Glade (it's highly superior to manual widget whacking in this case) and I wondered if the predefined menu items and buttons exist in Pike. Are they GTK or are they Gnome? They definitely look a lot better (say Next and Prev buttons for example). My Pike doesn't have Gnome support since my distribution doesn't have Gnome 1 (soon to be resolved when I install Debian though etc) and it would be nice to avoid depending on Gnome for such things as well. If it isn't obvious from the choice of conferences, this will end up being a Pike application.
