Click⚑
-
New: Invoke other commands from a command.
This is a pattern that is generally discouraged with Click, but possible nonetheless. For this, you can use the
Context.invoke()
orContext.forward()
methods.
Optimization⚑
-
New: Add tips on how to optimize your python command line tools.
-
Minimize the relative import statements on command line tools:
When developing a library, it's common to expose the main objects into the package
__init__.py
under the variable__all__
. The problem with command line programs is that each time you run the command it will load those objects, which can mean an increase of 0.5s or even a second for each command, which is unacceptable. * Don't dynamically install the package:If you install the package with
pip install -e .
you will see an increase on the load time of ~0.2s. It is useful to develop the package, but when you use it, do so from a virtualenv that installs it directly without the-e
flag.

Pydantic⚑
-
New: Copy produces copy that modifies the original.
When copying a model, changing the value of an attribute on the copy updates the value of the attribute on the original. This only happens if
deep != True
. To fix it use:model.copy(deep=True)
.
Operative Systems⚑

-
New: Introduce kitty the terminal emulator.
kitty is a fast, feature-rich, GPU based terminal emulator written in C and Python with nice features for the keyboard driven
