Although I don't work on vala, I certainly work with vala, and just yesterday I compiled one of my vala projects on the $9 CHIP computer and I couldn't be more pleased with the ease. For me as a vala user, the biggest frustration I have, and the number 1 reason I would NOT consider vala for a future programming project is the cumbersome documentation. For the future of vala, having usable documentation is an necessity.

Re: [Vala] getting the valadoc.org documentation on a local server
If it allows me to take the documentation with me, the lack of search isn't that big of an issue. Although I have downloaded a few devhelp packages, I have not been able to find out how to access the data in the the package with the devhelp application. Can you point me to a tutorial or some sort of instruction that covers installing new devhelp packages?

The problem is that GLib.List searches for items based on pointer
value, not the actual data. You have to either use remove_custom or
(a much better possibility) use the Gee collection library. It is
much easier to use from Vala then GLib collection classes, which
were never intended for use in such high-level language.
I meant find_custom() :) Anyway, Gee is the way to go.

Thanks, the Gee library worked like a charm although I would prefer to
not require another library for the application. If anyone is
interested, the updated code that uses Gee is
using Gee;
public static void main(string[] args)
{
ArrayListstring? al= new ArrayListstring(str_equal);
al.add(this);
al.add(is);
al.add(a);
al.add(test);
//remove the test

[Vala] removing an element from a list
Hello,
For an application that I am working on, I need to keep a collection of
strings and possibly remove a string from the collection. A list seems
to be a good way to manage the strings but when I try to remove() or
remove_all(), the list doesn't change. for example:
public static void main(string[] args)
{
Liststring list = new Liststring();
list.append(this);
list.append(is);
list.append(a);
list.append(test);
//remove test
list.remove_all(test);
foreach(string word in list)
{
stdout.printf(%s , word );
}
stdout.printf(\n);
}
The word test is not removed from the list. Am I doing something
wrong, and is there a better way to do what I need?

[Vala] reading and writing binary data
Hello, I am using GNet to read data from a file over http and then write the data to a local file. Everything works fine when I am reading a text file but when I read some sort of binary file the data gets corrupted. I believe the problem is caused by Vala converting the data that I read into a UTF8 string. One way to fix this problem is to read the data as a GLib.ByteArray but I couldn't find a way to iterate over ByteArray and extract a single byte. It may also be possible to pull the raw string data from the Vala string. Unfortunately I don't know how to do this. Any advice regarding reading and writing binary data would be greatly appreciated. jezra ___ Vala-list mailing list Vala-list@gnome.org http://mail.gnome.org/mailman/listinfo/vala-list

Having used lariamat's suggestion, my gnet-vapi was update to include

[Vala] problem with GNet Connhttpeventresponse
hello,
I am trying to retrieve the header_fields and header_values fields
from a GNet.ConnHttpEventResponse and I don't know how to extract the
data. The valdoc page
http://valadoc.org/?path=gnet-2.0::GNet::ConnHttpEventResponse states
that header_fields and header_values are weak string, but the GNet
documentation http://www.gnetlibrary.org/docs/gnet-conn-http.html
states that the fields are null terminating arrays of strings.
Using the function:
private void get_response_data(ConnHttpEventResponse resp)
{
uint response_code;
weak string header_fields;
weak string header_values;
//get the data from the structure
response_code = resp.response_code;
header_fields = resp.header_fields;
header_values = resp.header_values;
stdout.printf(response code:%.0f\n,response_code);
//how does the data in the header_fields get iterated?
}
I can get the data from the fields as a string but I want to get the
data as a string[] so that I can iterate over the data. Does anyone
have any suggestions?
Thanks for your time,
