playgroundtools 1.10.1

An interface for managing playground projects.

playgroundtools

An interface for managing playground projects.

Overview

This package is intended to provide a quick and easy way to set up Python "projects," each containing their own files, folders, virtual environment, and installed packages. This also includes the ability to run these projects (called playgrounds) and delete them. This can be done either through the CLI or through the interactive GUI (with limited capabilities). The exact configuration for the creation and execution of these playgrounds are found here, in the package's configuration file.

For example, creating an api playground results in the following file structure:

playground
│   .env
│   main.py
│   reset.py
│   settings.json
│
├───.venv
│       ...
│
├───api
│       config.py
│       crud.py
│       database.py
│       deps.py
│       models.py
│       schemas.py
│       __init__.py
│
└───requirements
        requirements.in

Commands

new: Creates a playground.

$ playground new [-h] [-i LIB [LIB ...]] [-v] -n NAME [-o OPTIONS] type

For example, to create an api project:

# We can specify a list of optional packages to install via pip by using the `-i` option
$ playground new api -n my_api -i requests -v  # verbosity can be set with the -v option

A customized creation can be accomplished through use of the -o option. See Configuration Formatting for more detail.

# `package` is a custom playground type
$ playground new package -n my_package -o "{\"author\": \"John Doe\"}"  # customization can be done via the `-o` option

run: Runs a playground.

$ playground run [-h] [-m MODULE] [-a ARGS [ARGS ...]] name

For example:

$ playground run console_app

delete: Deletes a playground.

$ playground delete [-h] name

For example:

$ playground delete jupyter_tests

config: Reads or modifies the configuration. See the Using the CLI section for more detail.

$ playground config [-h] [-k READ] {delete,set}

For example:

$ playground config set -k api.folders -v "[\"api\", \"api/routers\"]"

Graphical User Interface

Invoking playground-gui will open the interactive GUI, allowing for the creation and deletion of playgrounds.

Playground Settings

Settings for a playground can be configured via its settings.json file. The available options are:

• python: a path that points to the Python installation used to run the playground.
• module: the module to run (by invocation of -m {module})
• args: the arguments to pass to the module (-m {module} {args ...})

Configuration

To configure the installation of playgroundtools, utilize the config command in the CLI or manually edit the config.json file.

The available options are:

• folders: a list of folders that should be placed inside the playground upon creation.
• files: maps file names to lists containing the contents of the file by line.
• lib: the packages to be installed upon creation of the playground.
• module: the module to run when the playground is executed via -m {module}.
• args: the arguments to pass to the module upon execution (-m {module} {args ...}).
• (OPTIONAL) format: specifies strings that are used for interpolation (see below)

Formatting

Keys and values can be interpolated using one of the strings below in the format ${string} in the config.json file.

• name: the playground name.

Format strings can be customized to include common conventions. For instance, one can include an author key in the format section of their playground type to specify a default author when creating a package and reference it in the setup file of the playground by using ${author}. An example of the usage of these format strings is shown below, in the Using JSON section.

Format strings also allow flexibility in the creation of playgrounds. You can override the default values for these strings when invoking the new command in the CLI by specifying the -o option, followed by JSON which determines the value for these fields upon creation.

Using the CLI

config delete: Deletes a key from the configuration.

$ playground config delete [-h] [-k KEY] [-f FILE]

For example:

$ playground config delete "package"

Keys from a custom config file can also be deleted:

$ playground config delete -f user_config.json

config set: Sets a key in the configuration.

$ playground config set [-h] [-k KEY] [-v VALUE] [-f FILE]

For example:

$ playground config set -k "api.folders" -v "[\"api\", \"api/routers\", \"api/db\"]"

Configuration can also be added from a custom JSON file:

$ playground config set -f user_config.json

Using JSON

The config.json file simply contains configurations for different types of playgrounds. The settings for each type are specified by the available options aforementioned.

For example, to create a package type, one could use:

{
    // ...
    "package": {
        "folders": [
            "${name}",
            "tests"
        ],
        "files": {
            "setup.cfg": [
                // File contents go here...
            ],
            "pyproject.toml": [
                // File contents go here...
            ],
            "setup.py": [
                // File contents go here...
            ]
            // ...
        },
        "lib": [
            "${name}",
            "${formatter}",
            "${linter}",
            "${build}",
            "${upload}",
            "isort"
        ],
        "module": "${name}",
        "args": [],
        "format": {
            "formatter": "black",
            "build": "build",
            "upload": "twine",
            "linter": "flake8"
        }
    }
}
