Homebrew tap for BorgLab software
Homebrew aliases are alternate names for existing formulae.
For example, gtsam@latest is an alias for gtsam_develop, so running brew install gtsam@latest or gtsam@develop gives us the same result while being more elucidating.
As a prerequisite, we add the borglab tap
brew tap borglab/coreThis ensures Homebrew has access to all the formulae and aliases in the git repository.
Homebrew recommends using the release tarball to create build the formula automatically.
Unfortunately, this will not set the proper cmake flags and dependencies, hence it is recommended to copy an existing formula and modify it accordingly.
You can use the below command to create a formula skeleton.
The tar file is the release .tar.gz file which homebrew will use to build the library.
brew create --cmake --tap borglab/core <link to tar file>
Run audit checks on the newly created formula.
Here we assume we created a formula file called gtsam4.2.rb.
brew audit --new-formula gtsam4.2
Run in verbose mode to verify
brew install -v --HEAD borglab/core/gtsam4.2
An Alias is simply a symbolic link, but care must be taken that the link is relative to the Aliases directory.
To create an alias, do the following:
# Go into the Aliases directory
cd Aliases
# Create the symlink
# NOTE homebrew uses @ for versioning
ln -s ../Formula/gtsam4.2.rb [email protected]
# Go back to repo root
cd ../Now you can commit the symlink file to the repo and enjoy using the alias.
