Joplin Plugin Enhancement
Generate from the Joplin plugin template: https://joplinapp.org/api/get_started/plugins/
It contains several enhancement for both codemirror and markdown renderer.
Features
Pseudocode
Pseudocode block:
Codeblocks
Highlight.js based codeblocks
Image
Allow following md works:
{width=60%}This plugin can:
- Specific the width/height of the image with
{width=80px},{height=30},{width=50%} - Render the image
![]()in a<figure>block withfigcaption - Use the
altattribute as the figure caption, and display the caption under the image if not empty - Center alignment for image and caption
- Automatic image numbering
Table
Auto add row/column, delete column, and format table.
This part mainly comes from takumisoft68: vscode-markdown-table. Please refer to it for the feature description. I just convert the code from vscode's editor to joplin's codemirror. :)
Because I have no idea how to create a context menu, currently all the operations are triggered by shortcut:
| Function | Shutcut |
|---|---|
| Insert a row above/below | ctrl + shift + up/down |
| Insert a column left/right | ctrl + shift + left/right |
| Delete current column | ctrl + shift + backspace |
| Navigate to previous cell | tab |
| Navigate to next cell | shift + tab |
- It will automatically format your table code for alignment when navigation between cells with
tab - A new line is appended when trying to navigate to next cell from the last cell
Table column colorize from the plugin: hieuthi/joplin-plugin-markdown-table-colorize
Admonition Renderer in markdown editor
It supports both !!! style and ::: style admonitions.
You still need Admonition markdown extension plugin installed to render admonitions in the preview window & PDF exports. This plugin only renders admonitions in the markdown editor.
Enhanced blockquote support
- It supports
[color=red]item in blockquote area so that the blockquote can be rendered with the given color border. [name=SeptemberHX]and[date=20220202]- Automatically fold the
[xxx=xxx]to keep the editor clean
Inline/Block math renderer in markdown editor
It significantly hurts your joplin's performance for now, especially with lots of math block. Please refer to laurent22/joplin#6719
Disabled by default
Mermaid renderer in markdown editor
Search & Replace
Code mainly comes from https://github.com/zhuhs/codemirror-search-replace
Current Bug: Cannot save after replacement. User needs to manually modify the note to save the change (for example: add a space) It is disabled by default
Border for indent list in markdown editor
Clickable task checkbox in markdown editor
Codes mainly comes from Zettlr
Header tag render in markdown editor
It shares the same configuration as with the clickable task checkbox
Code mainly comes from Zettlr
Toggle Sidebar and Note List panel together
A button on the note toolbar to toggle the sidebar and note list panel together.
It should be useful when the horizontal space of your screen is tight :)
Render Front Matter to Nothing
It just renders the front matter to nothing. It is helpful when you try to keep the front matter part and avoid the unwanted rendered content.
Local file preview
Currently only local pdf file can be previewed.
Quick Commands
Type /command in the editor for quick input of table, mermaid, etc.
/table/graph/flowchart/sequenceDiagram/gantt/classDiagram/erDiagram/journey/now/tommorow/today
link/image/footnote renderer in the editor
Only single line image/link can be previewed. ctrl/meta + left click on the rendered widgets can open the urls/files
Link preview only works with PDF/video/audio files
Inline link and image are folded only.
Build
Building the plugin
The plugin is built using Webpack, which creates the compiled code in /dist. A JPL archive will also be created at the root, which can use to distribute the plugin.
To build the plugin, simply run npm run dist.
The project is setup to use TypeScript, although you can change the configuration to use plain JavaScript.
Updating the plugin framework
To update the plugin framework, run npm run update.
In general this command tries to do the right thing - in particular it's going to merge the changes in package.json and .gitignore instead of overwriting. It will also leave "/src" as well as README.md untouched.
The file that may cause problem is "webpack.config.js" because it's going to be overwritten. For that reason, if you want to change it, consider creating a separate JavaScript file and include it in webpack.config.js. That way, when you update, you only have to restore the line that include your file.
