Remder

Renders a live HTML view of a Markdown file. Bring your own editor.

Install

Use Coursier to add the remder-app launcher to your $PATH. For example (assuming ~/.local/bin is in your $PATH):

$ coursier bootstrap ph.samson.remder:remder-app_2.12:0.0.13 -o ~/.local/bin/remder-app

Check out Maven Central for the latest available releases and snapshots.

note: If you don't have coursier, see here.

Use

Provide the markdown file as an argument to remder-app.

$ remder-app README.md

This launches the preview window. Edit with your favorite editor and remder automatically picks up and renders any changes when you save your edits.

Use with Vim

I use vim-markdown for my own markdown editing needs. In my ~/.vimrc I map \r to launch remder-app.

autocmd Filetype markdown nmap <leader>r :w \| :silent !remder-app '%' &<CR>

Embedded Diagrams with PlantUML

You can embed PlantUML diagrams as a uml code block.

```uml
Alice -> Bob: Authentication Request
Bob --> Alice: Authentication Response

Alice -> Bob: Another authentication Request
Alice <-- Bob: another authentication Response
```

Sequence diagrams work out of the box but for other diagram types you will need to have Graphviz (the dot command) on your system. See PlantUML Installation notes.

View in Browser

To view a (static) rendering in your default browser, press b on your keyboard. There you'll have all the nice things your browser can do for you like printing your document and copy-pasting the rendered HTML into Gmail or Google Docs. (Actually, in my testing, copy-pasting rendered HTML from the remder view works on Mac OS X but not in Fedora).
