Allow to select task via fuzzyfind (fzf)

[thrien]

Feature Request

Allow to select a task by content instead of linenumber, e.g. via a fuzzyfinder. In all cases where a mandatory task is not provided it is chosen interactively.

Example

I've used fzf as a convenient fuzzyfinder on the commandline to show how this could work:

If you don't specify a linenumber you get an interactive prompt to select one.

For this simple preview I changed line 1224 to:

    [ "$#" -eq 0 ] && set -- "$(_list "$TODO_FILE" | fzf --height=~10 | awk '{ print $1 }')"

Implementation

I need some guidance by someone more familiar with the code to come up with a proper implementation.

• What's the cleanest way to get all the tasks/lines with linenumber prefixed but without prompt, etc. ?
• It probably makes sense to write a function for this.
  • Does it to respect anything else apart from TODO_FILE?
• Since this feature will add a new dependency it would need to be checked beforehand.
  • Where is the best place to do this?
  • Should there be an option to allow/force/deactivate this feature?
  • How to check if terminal is interactive? (that's something I can probably figure out myself)

You can do it with an alias:

todo.sh do $(todo.sh ls | head -n-2 | fzf --ansi | cut -d' ' -f1)

I think maintainers wants to keep main script as simple as possible.

Okay, fair enough. Maybe that's a feature for one of the many apps built on top of it.

Then let me just mention for future reference how to use dmenu in this case. With these two patches

• fuzzymatch
• printindex

it can be nicely integrated as follows

dmenu -w "$WINDOWID" -F -ix -p "Select a task:" < "$TODO_FILE" | xargs expr 1 +
