Possible improvement to error message — what do you think?

I couldn’t get those to work in supecollider though, even when running in the terminal

24

I tried in C++ and it worked… Maybe sclang changes the string??? what happens with two slashes \\ ?

#include <iostream>

const std::string RED = "\033[31m";      
const std::string GREEN = "\033[32m";   
const std::string YELLOW = "\033[33m";
int main() {
    std::cout << RED << "This is red text."  << std::endl;
    std::cout << GREEN << "This is green text."  << std::endl;
    std::cout << YELLOW << "This is yellow text."  << std::endl;
    return 0;
}

EDIT: I’m kind of surprised that sclang never implemented colors in the post window

25

In terminals, "asdf".error does not produce coloured text. I imagine the colouring is QT looking through the post window for strings beginning “ERROR:”, “->” and “WARNING” and colouring the line.

Do you know what it would take to make colour codes work?

27 
int prPostString(struct VMGlobals* g, int numArgsPushed) {
    PyrSlot* a;

    a = g->sp;
    // if (NotObj(a)) return errWrongType;
    // assume it is a string!
    postText(slotRawString(a)->s, slotRawString(a)->size);
    return errNone;
}

int prPostLine(struct VMGlobals* g, int numArgsPushed) {
    PyrSlot* a;

    a = g->sp;
    // if (NotObj(a)) return errWrongType;
    // assume it is a string!
    postText(slotRawString(a)->s, slotRawString(a)->size);
    postChar('\n');
    return errNone;
}

I think not possible without changing something in the interpreter, the language can’ t do this I think.

yep:

So you can see why formatting only applies to a single line…

Adding one or two more string hooks for the sake of error formatting could be reasonable (those strings could even be scrubbed from the actual output).

The Post Window would not work with ANSI codes, but that would work in other environments. In any case, a solution inside the IDE would be easier to improve than what QtCollider already does. (But I believe a programming language should be used in different contexts, and editors should not ignore ANSI code sequences.)
