pyqa 0.5.2

pyqa makes it easy to write conversational scripts that generate configuration

pyqa makes it easier to write terminal based tools which ask the user a bunch of questions and then generate some configuration file based on the answers.

Usage

See /demo for a working example.

pyqa provides single function, “ask”. It expects a set of questions given in a specific format. The following description is in YAML but you are free to use any other markup language as long as the output matches:

---
id: project_name # id to use at the template
q: Could you please give the project name? # question shown to the user
---
id: license
q: Please pick a license for your project?
choices: # if choices field is used, the user will see these as numbered choice
    - BSD
    - GPL
    - Other
matches:
    Other: Please enter the license name -- define custom question for "other" case
---
id: use_fizzler
q: Are you sure you want to use fizzler?
type: boolean -- this will accept either true or false answer and emits True/False

Note that keywords “Yes” and “No” seem to be converted to booleans by YAML. If you need to use those within choices, remember to use explicit form (ie. “Yes” instead of Yes).

After the user has finished answering “ask” will return the results in a format like this:

{'project_name': 'myproject', 'license': 'BSD', 'use_fizzler': True}

This format happens to be compatible with pystache (Python version of mustache) and no doubt with many other template engines. Just pass that data to your favorite engine, render and output the file somewhere. Voilá!
