Python Tools

python_tools.bsh

Functions to help communicate with python

array_to_python_ast_list_of_strings

Arguments:

$1 - Variable to set result to. If the destination is an array, it will be unset (and become global)
[$2…] - Array elements (to be treated as strings)

Set $1 to a python ast.literal_eval compliant string for an list of strings

Example

array_to_python_ast_list_of_strings x 1 '1"1' "2'2" stuff
# x=["1", "1\"1", "2'2", "stuff"]

array_to_python_ast_list_of_literals

Arguments:

$1 - Variable to set result to. If the destination is an array, it will be unset (and become global)
[$2…] - Array elements (to be treated literally)

Set $1 to a python ast.literal_eval compliant string representing a “list of strings”

Example

array_to_python_ast_list_of_literals x 1 '"1\"1"' "\"2'2\"" 3.3
# x=[1, "1\"1", "2'2", 3.3]

array_to_python_ast_list_of_literals x 1+1
# x=[1+1], valid for python eval, but not ast.literal_eval

array_to_python_ast_list_of_literals x "$((1+1))"
# x=[2], valid for ast.literal_eval

vsi::python::virtualenv_bin

Arguments:

$1 - Virtual environment path, do not include bin or Scripts
$2 - Name of binary to run, without .exe extension

A cross-OS compatible function to call a binary in a virtual environment folder that handles the differences between Windows and Linux.

Example

"$(vsi::python::virtualenv_bin "${my_python_dir}" pip)" install numpy
