Your script, when installed this way (it's called an editable install, will automatically be up to date even if you edit it - there's no need to reinstall it after editing.

Then, to install your script directly, you can type pip install -e. Then modify settings.ini as appropriate for your module/script. Instead, just copy the setup.py we have in the fastscript repo, and copy settings.ini as well. You don't actually have to write a setup.py yourself. With this, you can then just type test_fastscript at any time, from any directory, and your script will be called (once it's installed using one of the methods below). in this case we use: test_fastscript=fastscript.test_cli:main. The trick to making this available as a script is to add a console_scripts section to your setup file, of the form: script_name=module:function_name. As you see, it's basically identical to the script example above, except that we can treat it as a module. To use it, follow this example from fastscript/test_cli.py in the repo.

There's a really nice feature of pip/setuptools that lets you create commandline scripts directly from functions, makes them available in the PATH, and even makes your scripts cross-platform (e.g. If you don't provide a default for a parameter, then it will be a positional parameter. You should provide a default (after the =) for any optional parameters. opt is a bool that defines whether a param is optional or required (positional) - but you'll generally not need to set this manually, because fastscript will set it for you automatically based on default values. Generally you'll want to pass at least help (since this is provided as the help string for that parameter) and type (to ensure that you get the type of data you expect). Except for opt, all of these are just passed directly to argparse, so you have all the power of that module at your disposal. You can pass the following when calling Param: help, type, opt, action, nargs, const, choices, required. As a bonus, we can also use this function directly from a REPL such as Jupyter Notebook - it's not just for command line scripts! ParamĮach parameter in your function should have an annotation Param(.) (as in the example above). Test_fastscript.py: error: the following arguments are required: msgĪs you see, we didn't need any if _name_ = "_main_", we didn't have to parse arguments, we just wrote a function, added a decorator to it, and added some annotations to our function's parameters. When you run this script, you'll see: $ python examples/test_fastscript.py Here's a complete example - it's provided in the fastscript repo as examples/test_fastscript.py: from fastscript import * def main ( msg : Param ( "The message", str ), upper : Param ( "Convert to uppercase?", bool_arg ) = False ): print ( msg.

In fact, it's <50 lines of code! Basically, it's just a little wrapper around argparse that uses modern Python features and some thoughtful defaults to get rid of the boilerplate. There are much fancier modules to help you write scripts (we recommend Python Fire, and Click is also popular), but fastscript is very fast and very simple. You can use argparse for this purpose, which comes with Python, but it's complex and verbose.įastscript makes life easier. But in Python, that involves a whole lot of boilerplate and ceremony, especially if you want to support command line arguments, provide help, and other niceties. Sometimes, you want to create a quick script, either for yourself, or for others. Part of fast.ai's toolkit for delightful developer experiences. A fast way to turn your python function into a script.
