easmx

A fork of the asmx assembler, slightly extended for the VSCode KC IDE extension.

What's new:

• use cmake as build system with a WASI build preset
• split build into a library and executable
• incbin opens files in binary mode (rb)
• add a -i [dir] cmdline option to provide a root directory for includes (important for platforms without the concept of a current working directory, like WASI)
• add a -m [filename] cmdline option to generate a .map file (maps machine code addresses back to source files and line numbers)
