bug tracker
by Martin Bähr 15 Aug '05

15 Aug '05

hi, i am wondering about the state of bug tracking. www.gotpike.org points to alexanders bug tracker which doesn't really seem to get used, while the old tracker at community.roxen.com still sees some use. when alexander set up the tracker, the initiative was welcomed, which seems to indicate that some were not all to happy with crunch. but is hasn't cought on yet. does anyone care which tracker is used? should we point people to both or what would you like to happen in the future? for now i have added a pointer to crunch in the developers section. (something which i started in march, no idea what got me sidetracked, i guess i need a taskmanager for myself) greetings, martin.

@ for mappings?
by Martin Bähr 15 Aug '05

15 Aug '05

hi, just had a thought for a nice feature that i don't remember having come up here before: for a function with lots of optional arguments it would be nice to take a mapping and splice it up into the args: void foo(void|string s, void|int i, void|float f) could be called as: foo( @([ "f":5.3 ]) ) usefull? greetings, martin.

embedding
by Bill Welliver 15 Aug '05

15 Aug '05

I was wondering what the status was of embedding that was being worked on by a few people. I was wondering if it would be possible to get a status, and maybe a look at the code (even if it's non-working) Bill

7.7 changes
by Jonas Walld�n ＠ Pike developers forum 14 Aug '05

14 Aug '05

I question the correctness of the changes checked into 7.7 last night by Nilsson (CVS comment "No longer allocate unused space for terminating char."). The +1 was not intended for accomodating a terminating character but to make sure zero-sized images get handled correctly in case malloc(0) returns NULL.

How to write utf-8 string to console?
by 墳墓 13 Aug '05

13 Aug '05

I'm trying to parse a XML file with UTF-8 encoded, I have figure out how to use Parser.XML module and it works fine. But there is a problem, I can't write the UTF-8 string I read from the file, but I could use GTK2 module to display those string. When I tried use write() to let it display on console, Pike compilan: ================================================= Stdio.File->write(): cannot output wide strings. _static_modules.files()->Fd: Fd(1)->write("\110112\61062\n") aa.pike:21: /home/brianhsu/aa()->main() ================================================= And when I use those string at the GTK2.Lable->create() , it also says : ================================================= Bad argument 1 to create(). Expected string (8bit). ================================================= But I can first create an empty label, then use set_text() to set the conent of the label. Where should I check my code? My XML file: http://stu.im.ncnu.edu.tw/~brianhsu/test.xml Here is my code,I commemted out the code that have these problem. ================================================= import Parser.XML; int main () { string xml = Stdio.read_file ( "test.xml" ); Tree.Node root = Tree.parse_input ( xml ); string test = root->get_children()[1]->get_tag_name(); GTK2.gtk_init(); GTK2.Window win = GTK2.Window( GTK2.WINDOW_TOPLEVEL ); win->set_default_size ( 320 , 240 ); // Faild //GTK2.Label lab = GTK2.Label ( test ); // Faild //write ( test + "\n" ); GTK2.Label lab = GTK2.Label ( "" ); lab->set_text ( test ); win->set_title ( test ); win->add ( lab ); win->show_all(); return -1; } =================================================== -- ~ 白馬帶著她一步步地回到中原。白馬已經老了，只能慢慢地走， 'v' Brian Hsu 但終是能回到中原的。江南有楊柳、桃花，有燕子、金魚…… // \\ ( 墳墓 ) /( )\ 但這個美麗的姑娘就像古高昌國人那樣固執。【白馬嘯西風】 ^`~'^ http://bone.twbbs.org.tw 『那都是很好很好的，可我偏不喜歡。』

pike reserved keywords
by Martin Bähr 12 Aug '05

12 Aug '05

hi, trying to make a complete list of reserved words in pike. i found all of these in language.yacc, and i hope the list is complete. they are grouped loosly by type, with each line representing a subgroup based on a gut feeling. i would appreciate any suggestions for better categorization, and expecially any explanations of what the keywords in the last two groups do. types: array mapping multiset object function program string float int void mixed related to types: constant enum typedef flow control: if do for while else foreach case switch break continue return special "functions": sscanf typeof special blocks: catch gauge class lambda don't know how to name that group: import inherit class access: final static private local public protected i don't know what these do, but they seem to belong to class access: nomask inline extern optional variant i have no clue what these are: default predef global

type incompatibilities in connection with inheritance?
by Martin Bähr 11 Aug '05

11 Aug '05

hi, the tutorial makes this mysterious claim: http://pike.ida.liu.se/docs/tutorial/oop/access_control.xml If a class has a constructor (that is, a method called create) it can be a good idea to declare it static. It is not supposed to be called except during the construction of the object, and if it is not static there may be some type incompatibilities in connection with inheritance. what exactly is that supposed to mean? i understand the use of static to protect create from access from the outside, but what kind of type incompatibilities can there be for inheritance? and how can static protect against them? greetings, martin.
