How to turn REStructeredText into html?

[Nite Coder]

Is there a way I could transport the KTextEdit to another distro that isnt't KDE?
Because I am making this for someone else who runs a machine with Bodhi.

Hi , its just a Widget. If /when you can get it to compile,
you can use it on any platform where you app can run.
The only real issue can be it depends on other stuff from KDE, which you also need then.
Its a Qt widget so not tied to KDE as windows manager.

Right! Forgot I am a year into programming and therefore forget critical details such as that! But by any chance do you know what things it depends on?

Hi
Seems pretty clean, from first look

Seems pretty clean

It's not a walk in the park but every module is built with CMake so once you compile 1 the rest should be easy

Ah, thx. i looked for the Tier label but i looked wrong place.
Its tier 3? it seems so thats some mean park agreed.

So I have been working on a parser but I have run into some issues!
I have a parser and it crashes every time I use it!

It runs fine until I select the reStructeredText option and type something
The error when I debugged was SIGABRT
When it fails it just says it exited with code one.
I am pretty certain it is the parser

Here is my code:

main.cpp

#include "mainwindow.h"
#include <QApplication>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QCoreApplication::setApplicationName("SHtmlPlay");
    QCoreApplication::setApplicationVersion(QT_VERSION_STR);
    QCoreApplication::setOrganizationName("Sash");
    
    MainWindow w;
    w.show();

    return app.exec();
}

Thanks for any help in advance

Hi,

What does the stack trace of your crash tell you ?

[Nite Coder]
