Add a Robot Framework configuration source

[bollwyvl]

Elevator Pitch

Allow loading tasks from .robot files.

Motivation

Robot Framework is a human-readable (if quirky) text format written in Python, often used for defining acceptance tests with a large library and tooling ecosystem. It also provides a Task-driven syntax, which is close to supporting the doit task model.

Design Ideas

• writing
  • use "free metadata" and tags for doitoml configuration
• parsing
  • use the native data model for parsing
• running
  • for each task, generate a robot.main invocation that matches just the test of interest
    • inject the whole to_dict back in for task execution
• reporting
  • offer a place to put output data

# my_tasks.robot
*** Settings ***
Library     Operating System                        # reuse robot things
Library     dodo                                    # load a dodo.py as a module
Metadata    
...    doitoml:prefix          robot           # configure doitoml
       doitoml:paths:input     input.html      # define variables
       doitoml:paths:output    output.html     # can't be lists :_(

*** Tasks ***       # also support templates?
Copy the HTML
    [Documentation]  Hoist this to `doc`
    [Tags]    doitoml::file_dep::input    doitoml::targets::output
    Copy File    @{::input}  @{::output}  # supports lists as variables
    Do Another Thing  @{::input}

*** Keywords ***
Do Another Thing    # create keywords
    [Arguments]  ${value}
    Log   ${value}
    Log   ${::another-ns::thing}
