This package procures the command-line tool pyh
. It works somewhat like UNIX's
man
, but for Python's docstring-based help system. In a nutshell:
$ pyh print
print(...)
print(value, ..., sep=' ', end='\n', file=sys.stdout, flush=False)
Prints the values to a stream, or to sys.stdout by default.
Optional keyword arguments:
file: a file-like object (stream); defaults to the current sys.stdout.
sep: string inserted between values, default a space.
end: string appended after the last value, default a newline.
flush: whether to forcibly flush the stream.
A more complex example:
$ pyh pathlib Path.is_file
Help on function is_file in module pathlib:
is_file(self)
Whether this path is a regular file (also True for symlinks pointing
to regular files).
To shorten the command lines a bit, one can configure a set of their favorite aliases for modules names in file
$XDG_CONFIG_HOME/pyh/aliases
(which typically resolves to $HOME/.config/pyh/aliases
). The alias file is written in
the NestedText format, which looks similar to YAML. One simply encodes an
alias-to-module name dictionary, one line per entry. Example:
pd: pandas
pl: pathlib
ap: argparse
pip install pyh
Setting up the development environment relies on Conda. Clone the repository, cd
into the local copy, then
$ conda env create
Dependent packages are managed through the environment.yml
file. When changing dependencies, update the development
environment with command
$ conda env update
