Hi Fellippe and Bert22306,
The IDE depends on the compiler. The compiler doesn't depend on the IDE. Any IDE can be used with QB64, provided it has settings for command line compilation, which QB64 supports since forever.
Sure, I can use antother IDE that calls qb64 -x XXX.bas -o YYY iff well interfaced such as notepad++ on Windows (I dream to have it with both Linux and macOS) !
But if the QB64 old fshioned IDE depends of the compiler (because it's written in QB64 language) this isn't a good reason for having its source code completely imbricated into the compiler source code.
As a matter of fact, we could have for the best of both the compiler (the language itself) and its current IDE two different programs, one the compiler alone, and two, the IDE that would be compiled, then calling the compiler for its own projects.
As said early, I know that's a big job to do but there is no technical and objective reason for continuing the original "lack of design (of the cpmplete project)" of these two excellent programming tools.
That's just my point further allowing to enhance the IDE and/or the Compiler separately without creating "bugs" of one to the other.
Just my two cents.
BTW, I love the QB64 language even if I'm not an expert.
Cheers.
