Custom output file

[duhow]

Describe the solution you'd like Add an argument to asmsx to generate another filename. All generated artifacts (SYM, TXT, ROM) must have this name as well.

This supersedes .FILE command.

Example:

asmsx test.asm -o MegaGame.Rom
# extract extension if present, and apply only to ROM, not to TXT/SYM. Other files must be named 

• Update help command
• Update docs
• Add test for file with extension (case-sensitive), and without ext

Describe alternatives you've considered

Additional context

[Fubukimaru]

Add test for file with extension (case-sensitive), and without ext

Do you expect for example the following commands to be functional?

asmsx test.asm -o MegaGame.Rom

asmsx test.asm -o MegaGame

The extension is currently being inserted in the write_bin function as it can be determined by some pseudoinstructions found in the code (e.g., ROM pseudo).

Making the second work would be easy. The first one might be trickier.

Also, if you say -o whatever.rom but inside you have the command to make a .com. Should it complain?

[duhow]

People may (wrongly) provide output file with or without extension, but it can also happen that any extension is provided, so we can't discard it...

asmsx test.asm -o MyGame.es
# don't remove extension, as we want MyGame.es.rom

So either we define any input as FILENAME, or we can skip certain / specific extension suffix.
