CLI Usage

Usage: ibi [OPTIONS] COMMAND [ARGS]...

  Library and CLI for generating installation instructions from json schema
  and jinja templates.

Options:
  --version   Show the version and exit.
  -h, --help  Show this message and exit.

Commands:
  install  Installs with config and parameters given.
  show     Shows installation instructions for your specified config file...

Options are dynamically created with the schema part of the config file.

Config

• The config is comprised of a single file install.cfg.
• The config has two parts delimited by ------ (6 or more -).
• Both parts should be developed in different files for language server support.

Schema

• The first section of the config is a json-schema.
• It can be written in JSON or to JSON capabilites restricted YAML.
• When creating a schema use the following schema draft version: https://json-schema.org/draft/2020-12/schema
• title are used for pretty print option names.
• description is used for the options help message.
• For adding a description and a pretty print name to enum values (for web-installation-instruction):
  1. Indent the schema with the key schema.
  2. Add pretty and description keys.
  3. Create lists like key: Pretty Key.
• title and description from within the schema overwrite pretty and description outside of the schema.
• For the package to set the default os to the running system, name the property __os__.

schema:
  name: installation-instruction
  type: object
  properties:
    method:
      enum:
        - pipx
        - pip
pretty:
  pipx: Pipx
  pip: Pip
description:
  pipx: Installs python packages into virtual environments.
  pip: Standard python package manager.

Template

• You can have as much whitespace and line breaks as you wish in and inbetween your commands.
• Commands must be seperated by &&! (pip install installation-instruction && pip uninstall installation-instruction.)
• If you wish to stop the render from within the template you can use the macro raise. ({{ raise("no support!") }}.)
