# MARKTerm

Markterm is a library and program to render Markdown to
a terminal. It's inspired by [Glow](https://github.com/charmbracelet/glow)
and implemented using [Markd](https://github.com/icyleaf/markd)

## Features

* It will syntax highlight code blocks
* It will try to handle light and dark terminal themes. Since
  it uses the terminal's colors, it should match things like
  vs code themes in the vs code terminal, etc.
* In general it tries to look good and not gaudy
* It will do the right thing if output is not a tty
* Can be used as a library or as a program

## TODO

* ✅ Configurable themes
* ✅ Implement HTML-style links as supported in kitty/alacritty
* ✅ Don't break paragraphs on soft breaks
* ✅ Implement images as supported in kitty (requires timg, kinda buggy)
* ✅ Images in all terminals (requires catimg, kinda useless)
* ✅ Implement HTML block support
* ✅ Better textual image display when images are not supported
* ✅ Maybe only support timg with options
* ✅ Support being used in a pipeline
* Implement internal piping to $PAGER
* Allow enabling/disabling images/html-style-links via CLI (partly done)
* Use crystal-term/color to detect color capabilities
* Fix whatever bug is there

## Usage as a program

Either get a static binary from the [releases page](https://github.com/ralsina/markterm/releases)
or build from source:

* Install crystal
* Checkout the repo
* run `shards build`

This is the help:

```docopt
Markterm - A tool to render markdown to the terminal

Usage:
  markterm <file> [-t <theme>][--code-theme <code-theme>][-l]
  markterm -h | --help
  markterm --version

Options:
  -h --help                  Show this screen.
  -t <theme>                 Theme to use for coloring output
  --code-theme <code-theme>  Theme to use for coloring code blocks
  --version                  Show version.
  -l                         Force html-like links

If you use "-" as the file argument, markterm will read from stdin.
```

## Usage as a library

1. Add the dependency to your `shard.yml`:

   ```yaml
   dependencies:
     markterm:
       github: ralsina/markterm
   ```

In your code, use it like this:

```crystal
  puts Markd.to_term(source)
```
