Rule for running Python scripts

Description

This rule executes Python scripts to create various file outputs.

Usage

pythonRule(
  target,
  script,
  depends = NULL,
  args = NULL,
  python = "python",
  task = "all"
)

Arguments

target	Name of output files to be created
script	Name of the Python script to be executed
depends	A vector of file names that the Python script depends on, or NULL.
args	A string with command line arguments for the Python script. This string may contain variables ⁠$[DEP1]⁠, ⁠$[DEP2]⁠, ..., ⁠$[TARGET1]⁠, ⁠$[TARGET2]⁠, ... that are replaced with the corresponding file names from depends and target. If args is NULL, the arguments are created from the depends and target parameters, in that order.
python	The command to execute Python. By default, it is python, but it can be set to a specific path or to python3 if needed.
task	A character vector of parent task names. The mechanism of tasks allows grouping rules. Anything different from 'all' will cause the creation of a new task depending on the given rule. Executing ⁠make taskname⁠ will then force building this rule.

Details

In detail, this rule executes the following command in a shell: ⁠python script arguments⁠ where arguments are script arguments created from the args parameter. If args is NULL, the arguments are created from the depends and target parameters, in that order. If args is not NULL, it must be a string with command line arguments that may contain variables ⁠$[DEP1]⁠, ⁠$[DEP2]⁠, ..., ⁠$[TARGET1]⁠, ⁠$[TARGET2]⁠, ... that are replaced with the corresponding file names from depends and target.

Issuing ⁠make clean⁠ from the shell causes removal of all files specified in the target parameter.
