How do you have multiple todo.txt files under different folders?

[flyisland]

I would like to have a todo.txt file for each of my projects. I hope this todo.txt file is located in the project's root folder. What do you think I should do?

Sounds like you would need to override the TODO_DIR variable with the projects root folder.
So from the project root:
export TODO_DIR=$(pwd) todo.sh may just work, this would rely on the done.txt etc being in the project root also.

This sounds like a duplicate of #187. In general, having multiple todo files is discouraged (maybe except for having both personal and work-related tasks separately, which can be easily solved via two different config files and separate aliases). The recommendation is to have a single todo file and use +project (or @context). That said, I'm also experimenting with per-project todo files for very short-term tactical tasks.

What exactly constitutes a project is quite subjective, and there are multiple use cases to consider (e.g. how is a project defined, what happens when tasks are done, should there be a fallback to the global one). I doubt that there'll be a built-in ready-to-use solution in the foreseeable future (and have reservations about the "search upwards from the current dir" approach taken by #187). However, it's really easy to implement a custom solution; remember that the todo.cfg is a Bash script, too, so you can conditionally set TODO_DIR there if a project is detected.
