Manage different versions of homebrew packages

Project description

Brew Versions (brewv)

PyPI version Python versions

Manage multiple versions of your Homebrew packages with ease! Homebrew makes this difficult as a design decision, but sometimes old packages need to be installed and we need a way to do so easily.


With pipx

pipx install brew-versions

Or just with pip:

python3 -m pip install --user brew-versions


Switch to a specific version:

$ brewv switch wget 1.21
[brewv]: Switching wget to version 1.21
[brewv]: Not in cache: finding bottle to download
[brewv]: GET
[brewv]: Bottle successfully downloaded, but cannot verify SHA256
[brewv]: Pinning wget
[brewv]: Successfully switched to wget 1.21

Installing from taps:

$ brewv switch jonchang/biology/bucky 1.4.4
[brewv]: Tapping jonchang/biology
[brewv]: Switching bucky to version 1.4.4
[brewv]: Not in cache: finding bottle to download
[brewv]: GET
[brewv]: No bottle was found for bucky 1.4.4
[brewv]: Searching for version in git directory, this may take a while...
[brewv]: Found a version in commit: eee76a60fb5d7c6b619d736b50ee10fe42a9c73c
[brewv]: Found bottle in tap config
[brewv]: GET
[brewv]: SHA256 verified successfully
[brewv]: Pinning bucky
[brewv]: Successfully switched to jonchang/biology/bucky 1.4.4

When no bottle is found for taps it will proceed with searching the local tap repository for the correct version and installing from the bottle defined in the formula if it exists, otherwise from source.

This is very slow for the main homebrew repository so this behaviour is disabled when a bottle for a homebrew-core package cannot be found. You can supply the option brewv switch --slow ... to perform this search.


Proper SHA256 verification is not done when downloading bottles from the main bottle repository. This is because to get the expected SHAs would mean searching the huge homebrew-core repository.

While homebrew bottles exist for most operating systems, if the bottle is not found then parsing old formulas fails quite often since Homebrew updates their code frequently.
