Adjust the intMaxParts integer argument at the end of the script (the default 2 gives the @now line and its parent – 1 gives just the @now line – Infinity gives the whole path, other numbers give an ancestral path up to a maximum number of path segments long.
I’m not personally a user of BitBar, so I haven’t tested this, but glancing at their notes, it seems that all that is required is an (execute-enabled) bash script with a .sh extension, which returns a text.
If you save the following as an .sh file, you should be able to fine-tune it to generate the text you want.
This rough draft lists the first task which has a @now tag (any ancestral path delimited with arrows up to a maximum segment length).
To generate a different text, you can adjust the itemPath expression that is bound to the variable name strQuery, near the top of the script.
#!/bin/bash
osascript -l JavaScript <<JXA_END 2>/dev/null
(function (intMaxParts) {
'use strict';
// ver 0.3 Requires TaskPaper 3 Preview version 166
// (FIRST LINE TAGGED WITH @NOW and optionally a path to it)
// Increase the value of intMaxParts (argument at end of script)
// to lengthen the path displayed
var intMax = intMaxParts || 99,
// EDIT THE TASKPAPER 3 QUERY (itemPath) THAT YOU NEED
strQuery = '//@now[0]/ancestor-or-self::*[-' + intMax + ':]',
rgxBullet = /^- /,
strArrow = " -> ";
// ConcatMap A FUNCTION OVER A LIST
var strStep = function (xs, f) {
return [].concat.apply([], xs.map(f));
// LIST: LINES ANCESTRAL TO FIRST @NOW-TAGGED LINE IN FRONT TP3 DOC

options.query

return x.body.string;

This is very cool! But I can’t get it to work for some reason. The script seems to produce the right result when run in terminal, but all I see in Textbar is “.” where the task should be. Any ideas? Thanks!
@dgg I’m experiencing the same thing. Any ideas @complexpoint ? Perhaps this isn’t compatible with the latest version of Taskpaper? Very cool idea though.
