* Convert `js/util.js` to Typescript and add tests Besides converting `js/util.js` to Typescript, this change also adds `js/types.ts` that defines common types used in apple2js. Some of these types, like `byte` and `word` are for information only. * Convert `js/base64.js` to Typescript This also adds a new type, `memory`, that is either an array of numbers, or a Uint8Array. * Convert `js/ram.js` to Typescript This change does not convert `RAM` to a class; it just introduces types. * Basic typing of cpu6502 This is a really rough first pass. There are some problems that can't be fixed until this is turned into a real class, but at least all of the function arguments are now typed. This caught a few cases where extra arguments were being passed in. * Convert `js/cpu6502` to a class In theory, idiomatic classes should be better than the previous closure-based classes. However, this conversion shows that the instruction table does not fit well with idiomatic classes as method referenced in the table need to be called with the correct `this` everywhere. This should, at best, be considered a first attempt. |
