Pass bashly.yml through ERB about bashly

[DannyBen]

Released 1.0.7 with this feature.
Minimal docs here: https://bashly.dannyb.co/advanced/erb-in-config/

Thanks for the suggestion.

[DannyBen]

Good idea. Do you have a sample YAML use case?

[DannyBen]

The implementation is ready if you want to try it.
Let me know if it aligned with your use case.

use case:

commands:
  - name: completions
    help: |-
      Generate bash completions
      Usage: eval "\$(ansible completions)"

  - name: ansible
    help: Ansible related commands
    commands:
      - name: playbook
        help: Run Ansible playbook
        flags:
          - long: --playbook
            short: -p
            arg: playbook
            help: Playbook name
            required: true
            repeatable: false
            allowed:
              <%- Dir['playbooks/**/*.yml'].each do |f| -%>
                <%- _, dir, file = f.split('/') -%>
              - <%= "#{dir}_#{file}".gsub('_', '-').gsub('.yml', '') %>
              <%- end -%>

With a bit of Ruby code :

#!/usr/bin/env ruby

require 'erb'

yaml = ERB.new(File.read('vendor/ansible-cli/bashly.yml'), trim_mode: "-").result
puts yaml

it gives :

      - name: playbook
        help: Run Ansible playbook
        flags:
          - long: --playbook
            short: -p
            arg: playbook
            help: Playbook name
            required: true
            repeatable: false
            allowed:
              - install-apache
              - install-burp
              - install-dns
              - ...

And users can automagically autocomplete the --playbook flag :)

it does! thank you! ❤️

[DannyBen]

Ok cool.

1. Note that I did not use the trim mode '-' - I just used the default ERB settings:

bashly/lib/bashly/extensions/yaml.rb

Lines 8 to 10 in 44294bb

	def load_erb_file(path)
	YAML.load ERB.new(File.read(path)).result
	end

if there is any reason to load it differently in your opinion, let me know

2. I will release during the weekend
3. As I see you have some DevOps template manipulations to deal with - you might be interested in Kojo - I used it a lot to transform Kubernetes manifests into something more human friendly.
4. You know you can run bashly validate --verbose to see the rendered YAML, yes?

Seems nice, thank you!

I didn't know, thank you!

Actually I did something (a bit) similar but in Crystal : https://github.com/jbox-web/envtpl.cr
