Picomamba
==========





Mamba in the browser can be used in conjunction with python compiled to wasm from `emscripten-forge` 
The usage looks like:
```python
import picomamba

def callback(name, done, total):
    percent = 100.0 * done / total
    print(f"{name} {percent:.2f}% ({done}/{total})")

pm = picomamba.PicoMamba(
    env_prefix=env_prefix,           # the name of the env
    repodata_dir=repodata_dir,       # where to store repodata
    arch_root_url=arch_url,          # root url for arch pkgs
    noarch_template=noarch_template, # templated url for norach pkgs
    progress_callback=callback,      # report download progress 
)
await pm.fetch_repodata(
    arch_url=arch_url,       # url for arch repodata tar.bz2 file
    noarch_url=noarch_url    # url for noarch repodata tar.bz2 file
)
transaction = pm.solve(
    ["regex", "imageio", "numpy", "networkx"]
)
await pm.install_transaction(transaction)


import numpy
import regex
import networkx
```
the output would be
```
