@andrivet/z80-assembler v1.3.0

z80-assembler

A Z80 assembler library entirely written in Typescript and derived from a PEG grammar. It optimized for the old ZX81 computer but can also be used with any other Z80 targets.

Demo application

A demo application is available: https://andrivet.github.io/z80-assembler/.

Quick guide to use the library

To install the library:

$ npm install @andrivet/z80-assembler

The main function is simply called compile. It takes three arguments:

• the name of the source file
• the Z80 source code to compile
• a function used to return the content of included files

It returns an object of type CompilationInfo with the following fields:

• outputName: The name of the output as set by the output directive.
• bytes: A array of numbers. Each element represents a byte of the generated machine code.
• sld: The Source Level Debugging data as a string. This is used in order to debug the code.
• errs: An array of errors

A typical way to use the function is:

const info = compile(filepath, code, handleGetFileCode);
if(info.errs.length > 0)
  displayErrors(info.errs);
else
  saveOutput(info.outputName, info.bytes);

You can find a complete example in the demo application, in particular in the app.tsx file.
