Printing TaskPaper 3 documents with Marked 2 CSS templates

Here is a script for printing TaskPaper 3 documents through Brett Terspstra’s excellent Marked 2 71

Marked 2 lets you choose from a menu of alternative CSS templates, and exports to a range of formats, as well as printing directly.

The script simply:

• Copies the active TaskPaper 3 document to the clipboard (in Markdown format), and,
• if Marked 2 71 is installed and running on your system, displays a preview, allowing you to choose a CSS template and print or export.

(It doesn’t alter the TaskPaper 3 document itself – just places a markdown version in the clipboard)

A couple of ways in which you can keep the TaskPaper 3 side of things as simple as possible,
and delegate any formatting and meta-layers (when/if you need them) to Marked 2:

Automatic outline numbering (and rendering of simple inline Markdown style emphases):

Screen shot 2016-04-12 at 12.34.37.png512×660 45.6 KB

Running headers and footers,
and even, if your TaskPaper files grow huge, tables of contents

Added a few more printing options to ver 0.5 above:

{
    baseHeaderLevel: 4, // Integer 1-6  Render unindented projects as H1-H6
    hideProjectColon: true,
    markedStyle: 'Antique', // or empty string or undefined to use Marked default
    noteGap: true, // blank line between a task and its note text ?
    tagEmphasis : '*', // asterisk for italic, two for bold, backtick for code
    tagsToHide: ['alert']
        // ['*'] hides all tags in printed version
        // ['done', 'due'] hides @done and @due tags
        // [] hides no tags
}

Ver 0.06 updated above to allows for a small API change in 3.2 Preview (197)

(Should be backward compatible, I think)

The updated Keyboard Maestro version above now adds two options:

• Hide saved searches
• Hide folded and filtered

On speed, the script itself should execute fast.

Marked 2’s webkit technology needs a good amount of resource (it essentially contains a browser) so make sure that RAM is not full of many other programs.

To test the script alone, without Marked 2, temporarily edit out the bundle identifier in the following line, so that the strMarked2 variable name is just bound to an empty string;

 //var strMarked2 = "com.brettterpstra.marked2";
var strMarked2 = "";

The script will then simply generate a MultiMarkdown version of the TaskPaper document, and I think you should find that it does that fairly fast.

(If not, you could look in the Console.app logs for anything unusual, and let us know what hardware and OS X version you are using. If the bottleneck appears to be in Marked 2, you could ask for advice on the Marked 2 support forum).

First check is to run the source in Script Editor and see whether it places a Markdown version (with some HTML tags) in your clipboard

That means that the KM script hasn’t yet created the relevant variables

I’ve just downloaded the copy above and successfully run it from KM:

I suggest that you:

• Delete the copy currently in KM
• Download and install again
• Try to run it
• Then try a different hot-key to launch it (in case of some clash)
• and also run the dialog action with the KM Try button to make sure that it is creating the set of variables

(You can inspect the variables which KM knows about through the KM menu system: Preferences > Variables )

Can’t view your link from where I am but the next questions would be:

• Is the KM dialog displaying ?
• Is the clipboard content changing
• If you check that you have copied every line of the source script (not always easy and run in Script Editor, what does it now do, with the KM variables in place.

You are running this KM macro and the dialog is not showing ?

Possibly then a question for forum.keyboardmaestro.com

Just sounds like some difficulty in getting a macro to launch from Command-Option-P

I’ve just refreshed the .zip at Printing TaskPaper 3 documents with Marked 2 CSS templates - #5 by complexpoint above

Seems to be working fine here on:

• OS X 10.11.5 with
• TaskPaper 3.3 Preview (213) and
• Marked 2 Version 2.5.6 (922)

If you are still having difficulties, and your versions are the same as these, perhaps you could send me, through forum mail, the simplest TaskPaper 3 file (input and clipboard output) that you are seeing this with, together with any error messages (e.g. in Console.app).
