On `--list`, have different colors per namespace / included Taskfile

[andreynering]

Discussed in #824

This was originally asked for --list, but we could consider coloring the task name when running tasks as well.

For me, this would really help when output is set to prefixed.

Maybe having a color key on a task would be a good interface for users? Any task without a color would fallback to the default?

I know this idea involves color-coding namespaces when listing all tasks, but I've been thinking about creating groups to categorize tasks in the list. I currently do this manually with Makefiles, and it would be nice to have it here.

I implemented an example just to test:

The idea is to have a group field:

tasks:
  build:
    group: production
    desc: Build for production usage.
    cmds:
      - echo 'build...'

  start:
    group: development
    desc: Start the application.
    cmds:
      - echo 'start...'

Let me know what you guys think.

@betofigueiredo This has been requested before. Is there any reason you can't use namespaces for logical sorting/grouping?

[betofigueiredo]

I was thinking about something that could be implemented within a single file. However, in cases involving numerous tasks, it may be more practical to split them across different files. I looked for a similar feature request but couldn't find this one @pd93. Thanks for the reply.

@betofigueiredo FWIW, namespaces can be used without splitting into multiple files too. Just put a : in the task name (E.g. deveplopment:start) and it should work the same way.
