[DevQt] New versions, feature requests and bug reports

[michel]

thanks for your interest! I'll try to fix them all! :D

elcuco's kindness has no limits : he's gonna open a project on SF.net or Berlios because, for some reasons I can't do it on my own. That'll give us a better framework to speed up the developpement process.

I've no code to post today but I'm working on the project handling, damn progress : scopes are now understood and functions skipped

as soon as I'll get the project working I'll start compilation process stuff and post a version with as many fixes as possible.

Will your new version fix the syntax highlighter yet? I was going to post a modification to devhighlighter.cpp because the one from your latest zip file doesn't handle backslashes in preprocessor directives, but of course, now that it does handle them, the way your loops are set up it is not easy to check for a line that has both a backslash and a comment. It's rather simple. In your if loop for c=='#' just do an indexOf search for "\\" and if found set the state to preprocessor, and in your switch (previousBlockState()) - case statement at the top of the function put something like

case preprocessor :
                        i = text.indexOf("\\");
                        if (i != -1)
                        {
                               setFormat(0, i+1, fmts[preprocessor]);
                               return preprocessor;
                        }
                        setFormat(0, len, fmts[preprocessor]);
                        return normal;

case preprocessor :
                        i = text.indexOf("\\");
                        if (i != -1)
                        {
                               setFormat(0, i+1, fmts[preprocessor]);
                               return preprocessor;
                        }
                        setFormat(0, len, fmts[preprocessor]);
                        return normal;

I haven't done a lot of error checking but it seems to work fine for things like

#define THIS "that" \
           "plus this" \
          "plus that"
int main(){ printf(THIS); }....blahblah...

#define THIS "that" \
           "plus this" \
          "plus that"
int main(){ printf(THIS); }....blahblah...

In your old version only the first line would be green whereas all three lines which are part of the preprocessing should be.

Don't know if your comments scanner bothers to check for /* */ comments after the backslash, but it should be easy to implement. And you don't have to worry about the C++ style // comments after a backslash, because afaik they aren't legal to use in this syntax anyway and the compiler will complain about it.

ok going to bed. bbl

Not really a new release... but...

I have opened a site on berlios for this project. FMC and a few others already have write access to the SVN.

I would like to try the berlios forums for development communication, but IMHO, they are just lame. We will try it for a while, and if it does not work, we can still abuse this site (thanks!)

The site for this project is available at:
http://devqt.berlios.de/

We already have some downloads, check the download link on that site.

The development forum is at:
http://developer.berlios.de/forum/fo...forum_id=18460

Thanks for all that have been helping us with this project!

I downloarded the 0.1.0.zip and compiled.
This is the result on my linux qt 4.1 machine when trying to run it.

$ ./devqt 
Segmentation fault

$ ./devqt 
Segmentation fault

Wysota has already explained how to get rid of that AFAIK.

The embarrassing stuff pointed out by that stupid bug is that Qt doesn't behave the same on every system : on my Athlon 1,4GHz, 512Mb SDRAM, GeForce 2 MX400, Win ME (I know my config sucks but that's not the point!) no bug occured.

Anyway it has been removed but, I'm damn sorry, I can't post the last version here because the zipfile is 150kb while the limits set by the admins is 100kb!!!
So, if you want to keep updated you've got to visit http://devqt.berlios.de

Due to my 56kb internet connection and the troubles I get building an SVN client I can't post the code on my own so you also have to wait for elcuco doing it (I seny him the source a few minutes ago...)

It's not Qt. It's C++ and I can't believe you were able to dereference a random pointer on your system everytime you started the application

AFAIK the limit was changed to 300kB. Besides, you can always send a patch (diff) or only upload modified files. Using some better compressor than zip or reducing the size of icons is also an option.

As weird as it can seem it worked! And it comes from Qt because it's Qt that used the non initialized pointer, not my app!!!

That's right damn it!!! (sorry, private joke...)
I didn't noticed, thanks a lot!!!

What about a better compressor? I tried .rar but it only saved a few kb and not everybody has a decompressor for .rar files
BTW if you know a better, and as universal, compressor please tell me!

[Morea]

What about putting new versions on berlios.de more often?
Then posting links from here to berlios?

[Morea]

Well 0.2.1 (or 0.2.0 as the app called it self, or 0 as the resulting file is called ) looks promising.

One question though, will I be able to compile a single C++ file and run it, like a hello world program or should everything be in projects?

I will try to use it more as soon as I can change the font size in the editing window to something that is 400% larger. (on my linux box)

Sorry, compilation isn't implemented yet but single file comilation will be possible.
It will come with version 0.3.x!

Font settings should come soon but, well, they're not the part I'm focused on!

Hi,

I tested DevQt and found a small bug for the Explorer window (devdoc.cpp). Is it better to send a patch file or do you prefer to get these things here? In this case it was a tiny fix but what if I have more fixes? I've registred on BerliOS so that I now have the possibility to add patches (user KjellKod)

Anyhow: If explorer window was moved & docked to the right, and you then chose "Place on right" the (right click in explorer top) then you got both "Place on right" and "Place on left" as active, ref: attached picture. Fix: in the DevDoc constructor

if ( area & 3 )
	{
		allowedAreasActions->addAction(allowLeftAction);
		allowedAreasActions->addAction(allowRightAction);
                areaActions->addAction(leftAction);
                areaActions->addAction(rightAction);
                 leftAction->setChecked(true);  // This line is new. Setting default

if ( area & 3 )
	{
		allowedAreasActions->addAction(allowLeftAction);
		allowedAreasActions->addAction(allowRightAction);
                areaActions->addAction(leftAction);
                areaActions->addAction(rightAction);
                 leftAction->setChecked(true);  // This line is new. Setting default

It seems that the automatic 'Place on right', 'Place on left' when moving and docking the explorer does not work but I have not looked at why yet. This post is more of a test for me to get into the Open Source way of thinking since I am yet not part of any project

There are quite a few bugs in the menus and action options, afaict. For example, Close All doesn't close projects, Save All is an enabled option in the File menu even if nothing is open in the workspace or editor (it's enabled even when you first run the program), and there's a few other bugs that I commented on in the BerliOS forum for the project.

[elcuco]

Send unified patches (diff -u) to the patches section of the site. No direct link as of today, but I will do my best to add direct links to the pacthes page supplied by Berlios. (goto the download page, and then choose the patches link)

Please run the svn from the root of the project, is possible from an svn checkout.

BTW:
Mandrake sux, Galaxy more

As weird as it can seem it worked! And it comes from Qt because it's Qt that used the non initialized pointer, not my app!!!

It is your app which passes an invalid pointer to Qt routines, Qt just dereferences it using C++ "->" operator, so it is strictly a C++ issue. If you had zeroed the pointer at the beginning of the constructor, like you should, Qt would behave correctly (but with an unexpected result).

What about a better compressor? I tried .rar but it only saved a few kb and not everybody has a decompressor for .rar files
BTW if you know a better, and as universal, compressor please tell me!

Use bzip2. It has much better compression ratios than zip. Or tune the zip compressor to use the best strength available. And reduce the size of images. You can get rid of that .qm file too. It can be generated during compilation from .ts file.
