Script for use with Obsidian to pull in a snapshot of a day from Todoist

Obsidian Todoist Script.md

Obsidian Todoist Script

Description

This takes a day in YYYY-MM-DD format and can be called using the CustomJS plugin with either the Dataview plugin or the Templater plugin.

Styling

In order to get nicer styling, copy the todoist.css file to .obsidian/snippets and enable it under Settings → Appearance.

Callouts are generated as todoist-<todoist-color>-<project-name>, all lowercase, and hyphenated. You can customize the colors and icons by adding a .callout[data-callout$="project-name"] section to the CSS.

Dataview

Here is an example using dataviewjs in a Daily Note with the default file name pattern of YYYY-MM-DD.md:

```dataviewjs
const { Todoist } = customJS;
await Todoist.Callout(dv);
```

Templater

Here is the same thing using Templater:

<%*
const { Todoist } = customJS;
tR += await Todoist.getTaskMarkdown(tp.file.title)
%>

Advanced Usage

Using CustomJS, Templater, Dataview, and the Buttons plugins together, put this snippet at the bottom of a Daily Note:

```dataviewjs
const { Todoist } = customJS;
await Todoist.Callout(dv);
```

```button
name Save Tasks as Markdown
type append template
action Burn-in Todoist Tasks
replace [-12, -8]
remove true
```

Put the Templater snippet in the template file Burn-in Todoist Tasks.md.

Combined, this will create a dynamic Todoist view with a button that, when pushed, will vanish and replace the dynamic view with the hardcoded tasks.

How do I contact you directly? @dangle

Hello:)
Wonderful script:) Thanks a lot of it. It got me started experimenting with obsidian integrations.
As my setup is fresh and evolving I have got into a tiny issue that most seasoned Todoist users will likely not encounter:

Problem:

I have changed a name of a label in Todoist. Unfortunately tasks API returns labels by name:( It caused your script broke at line 264 with non existing color property.

Solution/workaround

Javascript is not my expertise area so there are likely more elegant ways to fix that(at least avoiding "magic constants", or choosing nicer color:)) Maybe there is something neutral your kebab function can accept without causing more stomach problems.
A workaround I am personaly ok with is to replace line 264 with:

(labels[label] == null)? "charcoal" : labels[label].color,

I thought I would share in case anybody else encounters that problem.
Thanks for a great script! :)

I'm trying to use this. I use the first above example:

const { Todoist } = customJS;
await Todoist.Callout(dv);

but i get the following error:

Do you know what is the problem?

It looks like you got an error from the Todoist API.

I'd have to see more of the error to know why for sure. Are your pages in the format YYYY-MM-DD.md? That's necessary for using the Todoist.Callout(dv); method.

If anyone is running into @dave58917's issues, for me the issue was that I needed to make sure the script was loaded in CustomJS's settings, not Templater's settings.

@fadialzammar I'm not sure I follow, can you elaborate?

Loving the concept!

Unfortunately, I cannot get the render as smooth and slick as visualized by you. I do have the .css snippet enabled.

Looking forward to your reply!
