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.

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>

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 Zenburn UDL file
npx markdown-plus-plus zenburn

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

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!!

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.
