Markdown Syntax Highlighting for Notepad++

This repo "markdown-plus-plus" is a project to support Markdown syntax highlighting in Notepad++. It is done via various User Defined Language (UDL) XML files. All UDLs are carefully designed by human, rather than generated by machine.

You can simply consume the UDL XML file that matches your favorite theme, or config your own using the build system.

Thanks for encouragements and comments. This repo is not only for myself anymore. It's for everyone.

Love Notepad++? Need to write docs in Markdown? This repo is made for you.

Usage

Node.js

If you had installed Node.js in your system, you can use npx command to get UDL file(s):

:: Check whether you have Node.js installed
node -v

:: Go to UDL folder of Notepad++. Usually...
cd %AppData%\Notepad++\userDefineLangs

:: Example: Download Solarized-light UDL file
npx markdown-plus-plus solarized-light

:: Example: Download Solarized UDL file for Dark Mode
npx markdown-plus-plus solarized --dark

:: Read help for details
npx markdown-plus-plus --help

You can choose to install this package in your system:

:: Enable `mpp` command instead of `npx markdown-plus-plus`...
npm install --global markdown-plus-plus

:: List all themes
mpp --list

:: Example: Download Solarized-light UDL file
mpp solarized-light

:: Example: Download Solarized UDL file for Dark Mode
mpp solarized --dark

:: Update this package
npm update markdown-plus-plus

Download Manually

1. Download the source code in latest release page. It should be a zip file.
2. Open the zip file and go to <udl\> folder.
3. Copy a XML file of your favorite theme, and paste in <userDefineLangs\> folder of Notepad++. The directory is usually <%AppData%\Notepad++\userDefineLangs\>.
4. Restart Notepad++.
5. Open and test with a Markdown file e.g. test/at-a-glance.md.

Enjoy!!

Dark Mode

Notepad++ features Dark Mode with great UDL enhancements since v8.1.3. In short, you may want 2 files:

:: Make sure you are running mpp v3.4+
mpp --version

:: Go to UDL folder of Notepad++. Usually...
cd %AppData%\Notepad++\userDefineLangs

:: Download Solarized UDL file
mpp solarized

:: Download Solarized UDL file for Dark Mode,
:: even though you use the same theme
mpp solarized --dark

NPP will pick up the correct file for dark mode. Here're some conventions in this package:

	Normal	Dark Mode
Command	mpp <theme-name>	mpp <theme-name> --dark
Filename	<markdown.theme-name.udl.xml>	<markdown.theme-name.dark.udl.xml>
UDL name	Theme Name (markdown)	Theme Name [markdown]

Limitations

Need your input to solve the following problems:

• _em text_, __strong text__ and ___em strong text___ only parse the first word because it will screw up some URLs such as example__url.
• Cannot use asterisk-style bullet points (* a \<li\> bullet point). Instead, please write in - a bullet point or + a bullet point.
• Improve documentations. My English sucks. (*´ｰ`*)
• The GFM's strikethrough ~~like this~~ is still missing. Will do it later.

If Notepad++ doesn't redraw your current markdown file(s), please re-open the NPP application and/or re-open the markdown file. Upgrade NPP may help.

Build Your Own UDL Files

The best way to build your own UDL file is to fork this repo. You need to install Node.js in your system.

:: In your dev folder
git clone https://github.com/Edditoria/markdown-plus-plus.git
cd markdown-plus-plus
npm install

:: Play around. Finally, run the build script
npm run build

For details, please read the document: build-workflow.md

Options

Options are reviewed in v3. In each config file in the config folder, you can adjust for your own build. Here are some examples:

Option	Descriptions
goodies.highlightHex	Highlight HEX value.
flags.transparentBg	Make the text background being transparent. ⚠️ Use it with caution
flags.asteriskUnorderedList	Enable the markdown style of asterisk-style bullet points (* a \<li\> bullet point). ⚠️ Use it with caution

For details, please read the document: build-workflow.md

Key Changes from v2 to v3

• Markdown-plus-plus is a npm package now. You can fetch the UDL files in command line directly, npx markdown-plus-plus --help.
• Build system relies on Node.js. git clone then npm install to develop this repo. Less dependency hell.
• In v2, there are 2 builds for every theme: Modern and classic. Now, there are only 1 build. The main difference in classic build, asterisk-style bullet points, becomes an option in v3.
• Better file structure:
  • You can find all UDL files in one single folder called <udl\>.
  • You can modify the config files in another folder called <config\>.
  • Filename for UDLs follows the pattern: <markdown.[theme-name].udl.xml>.
  • Filename for configs follows this pattern: <markdown.[theme-name].config.json>
