Homebrew-formula FlatCAM

This is an unofficial tap repository for homebrew FlatCAM to make installation on macOS easier.

Installation

brew tap tomoyanonymous/flatcam

# Beta 8.995 w/ PyQt6(https://bitbucket.org/marius_stanciu/flatcam_beta/src/Beta_8.995/)
brew install flatcam-evo
# Beta 8.994 w/ PyQt5(https://bitbucket.org/jpcgt/flatcam/src/Beta)
brew install flatcam-beta
# classic w/ PyQt4 (No more recommended)
brew install flatcam

After the installation, simply you can run the app from a command flatcam¹.

Note: If you failed to launch after upgrade, remove ~/.FlatCAM (temporary config directory).

Confirmed working on arm architectures.(OS Sequoia 15.5 / Macbook Air M1 2020).

3 versions of flatcam

Because flatcam is not strictly versioned, you can choose 3 different versions on this formula.

One is v 8.9.995, flatcam-evo, most frequently maintained version by Marius Stanciu, which uses PyQt6.

https://bitbucket.org/marius_stanciu/flatcam_beta/src/Beta_8.995/

Another is 8.9.94, flatcam-beta formula, which is on Beta branch on original repository mainly maintained by Stanciu, which uses PyQt5.

The last one is v8.5.0, on master branch of an original repo. https://bitbucket.org/jpcgt/flatcam which was developed by Juan Pablo Caram and no longer maintained by him.This version uses PyQt4. However, old Qt is not provided through from homebrew-core. Thus the formula depends on unofficial tap cartr/qt4. This formula is mostly kept on a historical purpose, not recommended to install anymore.

Also, note that flatcam package on pip is yet another unofficial version, which says the version is 0.8.5 but it uses pyqt5.

Why this formula is unofficialy maintained for years?

Because that the formula does some unrecommended manner in an installation, this formula won't be merged to homebrew-core.

Uses binary installation in pip install. Homebrew usually recommends to build a binary from source including python packages. However, ortools, one of dependencies does not provide a way to install it other than using wheel (built package for python). Thus, in the formula uses normal pip install -r requirements.txt. Also, requirements.txt seems to be missing descartes package so the formula will additinally install it.

Symlinks for main file In v8.5.0, the main executable file was flatcam but in Beta branch, it's FlatCAM.py. To use it from CLI directly, the formula prepends shebang #!/usr/local/Cellar/flatcam-beta/8.9.94/libexec/python and create symlink to the file in /usr/local/Cellar/flatcam-beta/8.9.94/bin/flatcam.
