diskii
======

**Note:** diskii is not stable yet! I don't expect to remove
functionality, but I'm still experimenting with the command syntax and
organization, so don't get too comfy with it yet.

diskii is a commandline tool for working with Apple II disk images.

It is also a library of code that can be used by other Go programs.

Its major advantage is that it's written in Go, hence
cross-platform.

Its major disadvantage is that it mostly doesn't exist yet.

It rhymes with “whiskey”.

Discussion/support is in
[#apple2 on the retrocomputing Slack](https://retrocomputing.slack.com/messages/apple2/)
(invites [here](https://retrocomputing.herokuapp.com)).

### Goals

Eventually, it aims to be a comprehensive disk image manipulation
tool, but for now only the `applesoft decode` command works.

The library code aims (a) to support the commandline tool operations,
and (b) to replace the "read and write disk images" code of the
[goapple2 emulator](https://github.com/zellyn/goapple2).

Current disk operations supported:

### Installing/updating
Assuming you have Go installed, run `go get -u github.com/zellyn/diskii`

You can also download automatically-built binaries from the
[latest release
page](https://github.com/zellyn/diskii/releases/latest). If you
need binaries for a different architecture, please send a pull
request or open an issue.

### Short-term TODOs/roadmap/easy ways to contribute

My rough TODO list (apart from anything marked (:x:) in the disk
operations matrix is listed below. Anything that an actual user needs
will be likely to get priority.

- [x] Build per-platform binaries for Linux, MacOS, Windows.
- [ ] Implement `GetFile` for DOS 3.3
- [ ] Add and implement the `-l` flag for `ls`
- [ ] Add `Delete` to the `disk.Operator` interface
  - [ ] Implement it for supermon
  - [ ] Implement it for DOS 3.3
- [ ] Make 13-sector DOS disks work
- [ ] Read/write nybble formats
- [ ] Read/write gzipped files
- [ ] Add ProDOS support (add `lib/prodos/prodos.go` and register a ProDOS operator factory)
