Path Tracking

Path Tracking

Modify how paths are tracked and made available through special variables.

• Proposal Status: wip

• Issue Number: 244

• Proposal Doc: path-tracking.md

Overview

There is some ambiguity about what the current directory is. Current logic is

• If remote, current dir is in providers dir

• If another dir, same thing but in that dir

Right now it is not clear what the current path / calling path actually is. This proposal will fix that.

Solution

Plan is to create a new path object and which stores all the path related data.

Variables:

• current path

  • The current path of the call. Can change based on chdir

• calling path

  • The path where tackle was originally called from

• tackle path

  • The path of the tackle provider being used.

  • base / hooks_dir / tackle_file

Schema

• Context

  • path:

  • current

    • directory

    • file

  • calling

    • directory

    • file

  • tackle

    • directory

    • hooks_dir

    • file

Situations

• Call from dir, tackle file in parent, call to remote tackle file, use generate hook

  • current_path = calling_path = cwd

  • tackle_file = the providers dir based on xdg

  • tackle_hook_path = the base dir, wherever the hook was defined, either tackle file or .hooks dir

  • generate hook attempts imports of templates from tackle_file_path and outputs by default in the current_path

• Call from dir, tackle file in parent, call to remote tackle file, use a declarative hook, use generate hook

  • same as above

Point is we have 2 situations,

1. When calling a local file / provider in the current or parent directory

• For those situations we have the current and calling paths

2. When calling a remote provider

• For that we have calling = current and tackle path for discriminating
