Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

We should also try to make the separators look better.

Right now it is like this:

Separators + border makes it crowdy, it looks like a grid.

Proposal:

Separators are a bit smaller, there is a bit more breathing room.

I added height equal to --ck-icon-size and removed align-self:

@oleq -- WDYT?

[oleq]

The change to separators looks fine but we need before/after screenshots for the following integrations to be sure it doesn't break anything:

• block toolbar,
• balloon toolbar,
• inline editor toolbar,
• grouped items (shouldGroupWhenFull),
• widget toolbars

I think all of them can be easily obtained by building docs with all samples.

[scofalik]

Adding screenshots of various builds, with various elements highlighted / focused to see how they look next to each other.

I also zipped them: separators.zip.

AFAICS, image is the only widget with a toolbar that has separators. Let me know in case I missed something.

LGTM.

Table toolbar is also declarative. Any using WidgetToolbarRepository can also be like this.

BTW: Have you noticed the code snippet in tableToolbar API? 🙃

[scofalik]

I guess they would look fine, if image toolbars look fine?

You mean that it is a bit... silly?

[Reinmar]

Did you test a solution with those separators shorter only by 2px (1px top, 1px bottom)?

How much shorter are there in this PR? Because my initial feeling is "quite a bit" and I wonder if smaller change would not work better.

Though, nothing critically bad about the screenshots that you posted. I just wonder what other optionss do we have.

[scofalik]

They are 6 pixels smaller, they are the height of the icon. I want to keep these separators scalable, so I based them on icon size, which is based on font size normal.

I can add some pixels using calc() though. But I think that smaller is better.

-6px (screens above):

-4px:

-2px:

-0px (current):
