Space after colon in project titles

Sometimes, when writing, I inadvertently add a space after the colon in the title of a project. The software immediately identifies the title as plain text, causing it to lose its title status.
I would like the software to also identify titles ending with a colon and a space as project titles.
Is it possible to change this behaviour in any way?

It may be easier to run a script which prunes any trailing space after project colons.

To test the script below:

  1. paste the full source code into Script Editor (there’s a copy button at top right of the expanded code display panel)
  2. set the language selector at the top left of Script Editor to JavaScript (rather than AppleScript)
  3. Click the Run button.

(With utilities like FastScripts and Keyboard Maestro, you can easily attach such a script to a keyboard shortcut)

    // ---------- TASKPAPER EVALUATION CONTEXT -----------
    const tp3Context = editor => {
        const outline = editor.outline;
        const rgxExtraSpace = /:\s+$/gu;

        let report = [];

        outline.groupUndoAndChanges(() => {
            report = outline.items.flatMap(item => {
                const s = item.bodyString;

                return rgxExtraSpace.test(s)
                    ? (
                        item.bodyString = s.replace(
                            rgxExtraSpace, ":"
                    : [];

        const n = report.length;

        return 0 < n
            ? `Fixed ${n} line(s):\n\n${report.join("\n")}`
            : "No trailing spaces found.";

    // ------------- JXA EVALUATION CONTEXT --------------

    // main :: IO ()
    const main = () => {
            doc = Application("TaskPaper")

        return doc.exists()
            ? doc.evaluate({
                script: `${tp3Context}`
            : "No document open in TaskPaper.";

    // MAIN ---
    return main();

If you start with with a TaskPaper file like the following, in which the 2nd and 3rd intended projects have lost their project status because of an unintended trailing space after the project colon:

then after running the script, you should find that the project syntax of those lines has been automatically fixed (any trailing spaces pruned out), giving you:


This is intentional. It’s needed because sometime people want to end a line with a colon and not have it recognized as a project. I think @complexpoint’s cleanup script is best bet.
