Building modern Zig from the original C++ implementation
--------------------------------------------------------

This repository explores building Zig from the C++ implementation without using
binary blobs. [Forum post goes with this][1].

Clone zig and prune binary files from history:

```
$ git clone --reference zig --dissociate https://github.com/ziglang/zig zig-nobinaries
$ cd zig-nobinaries
$ git filter-repo --prune-empty=never --prune-degenerate never --invert-paths --path-glob 'stage1/zig1.wasm*' --path stage1/zig1.c
```

Now build an isolated container with a bunch of zig historic dependencies:

```
$ docker build -t zig-repro .
$ docker run -ti --rm \
    -v ~/code:/x \
    -v /home/$USER/.cache/zig:/home/$USER/.cache/zig \
    -w /x/zig \
    zig-repro \
    sh -c "useradd -s /bin/bash -u $UID $USER && su $USER; bash"
```

And run the thing in the container:

```
$ ../zig-repro/run
```
