SYNOPSIS

mdp [OPTION]. . .  [FILE]

DESCRIPTION

mdp is a command-line program that allows you to make elegant presentations from markdown formatted FILEs.

It is as easy as write your presentation content in the text editor of your preference and launch the presentation from the command-line.

The input file from which the presentation is read. If no file is specified, or if the file name is -, the presentation is read from standard input.

MDP_LIST_OPEN1=' | '
MDP_LIST_OPEN2=' | '
MDP_LIST_OPEN3=' | '
MDP_LIST_HEAD1=' +- '
MDP_LIST_HEAD2=' +- '

MARKDOWN FORMATTING

For a complete list of supported markups, refer the sample presentation (sample.md) provided alongside mdp,  or online available at https://github.com/visit1985/mdp.

Slides

The input FILE is split into multiple slides by horizontal rules. Each consisting of at least 3 --- or *** characters on a single line. This line must be prefixed by an completely empty line. It can also contain spaces but no other characters.

If any slide is too large to fit into your current screen, an error message will be displayed at the moment the presentation is launched.

Line-by-Line Mode

Block-by-Block Mode

A single <br>, <BR> or ^ on an otherwise empty line signals mdp to stop output of the current slide (stop point) and wait for a key-press by the user.

This enables the user to display bullet points or list items one by one (line by line) or block by block.

Headers

mdp supports header lines in the format of @[DESCRIPTION] [VALUE] The first two header lines are displayed as title and author in top and bottom bar.

Headers are only recognized at the top of the input FILE.

Line spanning markup

Supported are headlines, code blocks, quotes and unordered lists.

In-line markup

As well as bold text, underlined text and in-line code.

COLOR SUPPORT

Most terminals are able to display 256 colors these days. But some of them enable only 16 colors by default. To enjoy mdp's full capabilities, these terminals need to be signaled to enable 256 color mode. This is usually done by setting the TERM environment variable.

export TERM=xterm-256color

KEYBOARD CONTROLS

h, j, k, l, Arrow keys, Space, Enter, Backspace, Page Up, Page Down

Display next/previous slide or continue after a stop point.

g, Home

Jump to first slide.

G, End

Jump to last slide.

1..N

Jump to Nth slide.

r

Reload the input FILE.  This key is disabled if input was read from standard input.

q

Exit mdp.
