I think it's the second part of your statement about automating tasks where CLIs really have the advantage. There's a lot of research out there that provides a lot of evidence that GUIs in general aren't slow, assuming they're well-designed they feel slower to people used to CLIs and keyboard-driven interfaces, but when you actually measure objectively with a stopwatch the results tend to favor GUIs. Personally I loathe having to use any sort of GUI because in general its slow and I cannot as easily automate tasks to customize my workflow. You could then return a machine-friendly serialisation of that in command server mode. If you were following this approach from the beginning, you would probably structure your CLI so that commands emit output in some structured form (eg a tree of named, typed values, or a table of named, typed columns), which is then rendered to the console somehow. The one real let-down is that the output is, AFAIK, the same as Mercurial's interactive output, which means the parent has to parse it with various command-specific regexps.

So, it's good code to integrate with, but exactly as powerful as the CLI. These are the same commands as you would use on the command line (interpreted by the same dispatcher, i believe, so really exactly the same). Communication is a machine-friendly framing protocol which allows the parent to execute Mercurial commands. This lets a process spawn a sort of daemon version of Mercurial, with which it can communicate via its standard input and output. Mercurial has an interesting take on this - the command server: With the library approach, it's easier for one to get ahead of the other. It also means that any functionality added to the CLI is also immediately available to the GUI. One advantage of building on top of the CLI rather than via a library is that it enforces the rule that any functionality available in the GUI is also available in the CLI. To some extent, this is what Git's 'plumbing' layer tries to be, although i don't know how successful it is. I wonder if you can design CLIs that are better to integrate with, though. Executable Python scripts will be in $(brew -prefix)/bin.A typical CLI might make a terrible piece of code to integrate with.

Brewed Python modulesįor brewed Python, modules installed with pip3 or python3 setup.py install will be installed to the $(brew -prefix)/lib/pythonX.Y/site-packages directory (explained above). Follow the pip documentation to install it for your system Python if you would like it. Note: macOS’s system Python does not provide pip. These should be installed via pip install. pyside, wxwidgets, pyqt, pygobject3, opencv, vtk and boost-python). If you decide to switch to the brewed Python, then reinstall all formulae with Python bindings (e.g. Warning! Python may crash (see Common Issues) when you import from a brewed Python if you ran brew install against the system Python. Additionally, Homebrew has a strict policy never to write stuff outside of the brew -prefix, so we don’t spam your system. The reasoning for this location is to preserve your modules between (minor) upgrades or re-installations of Python. Homebrew’s site-packages directory is first created (1) once any Homebrew formulae with Python bindings are installed, or (2) upon brew install python. ~/Library/Python/3.y/lib/python/site-packages.So, for Python 3.y.z, you’ll find it at /usr/local/lib/python3.y/site-packages. $(brew -prefix )/lib/pythonX.Y/site-packages Unversioned symlinks for python, python-config, pip etc. pip3 points to Homebrew’s Python 3.y’s pip (if installed).python3 points to Homebrew’s Python 3.y (if installed).The executables are organised as follows:

Manager such as pyenv if you require stability of minor or patch versions for virtual environments. Homebrew provides formulae for maintained releases of Python 3.y ( Python may be upgraded to a newer version at any time. Important: If you choose to use a Python which isn’t either of these two (system Python or brewed Python), the Homebrew team cannot support any breakage that may occur. A formula was provided until the end of 2019, at which point it was removed due to the Python 2 deprecation.

Homebrew provides formulae to brew Python 3.y. Homebrew should work with any CPython and defaults to the macOS system Python. See Python for Formula Authors for advice on writing formulae to install packages written in Python. This page describes how Python is handled in Homebrew for users.
