## 1. Usage
Using `parse` method, you can transform a markdown string into a terminal formatted content:
```ruby
parsed = TTY::Markdown.parse("# Hello")
puts parsed
# => "\e[36;1mHello\e[0m\n"
```
The `parse_file` allows you to transform a markdown document into a terminal formatted output:
```ruby
parsed = TTY::Markdown.parse_file('example.md')
puts parsed
```
### 1.1 Header
Parsing the following markdown headers:
```markdown
TTY::Markdown
=============
**tty-markdown** converts markdown document into a terminal friendly output.
## Examples
### Nested list items
```
The terminal output looks like this:
### 1.2 List
Both numbered and unordered lists are supported. Given a markdown:
```markdown
- Item 1
- Item 2
- Item 3
- Item 4
- Item 5
```
The parsed output looks like this:
### 1.3 Definition List
Given a definition list:
```markdown
Item 1
: This is the description for Item 1
Item 2
: This is the description for Item 2
: This is another description for Item 2
```
The parsed output looks like this:
### 1.4 Link
A markdown link:
```markdown
[An inline-style link](https://ttytoolkit.org)
[An inline-style link with title](https://ttytoolkit.org "TTY Toolkit Homepage")
```
The link text will be rendered with the link next to it:
### 1.5 Blockquote
Given a markdown quote:
```markdown
> Blockquotes are very handy in email to emulate reply text.
> This line is part of the same quote.
> *Oh*, you can put **Markdown** into a blockquote.
```
The rendered output looks like this:
### 1.6 Code and Syntax Highlighting
The parser can highlight syntax of many programming languages.
Given a markdown codeblock with a language specification:
````markdown
```ruby
class Greeter
def hello(name)
puts "Hello #{name}"
end
end
```
````
The terminal output will look like this:
### 1.7 Table
You can transform tables which understand the markdown alignment.
For example, given the following table:
```markdown
| Tables | Are | Cool |
|----------|:-------------:|------:|
| col 1 is | left-aligned | $1600 |
| col 2 is | centered | $12 |
| col 3 is | right-aligned | $1 |
```
Then the terminal output will look like this:
### 1.8 Horizontal Rule
You can specify a horizontal rule in markdown:
```markdown
***
```
and then transform it:
```ruby
parsed = TTY::Markdown.parse(markdown_string)
```
`puts parsed` will output:
### 1.9 Footnotes
You can create footnote references:
```markdown
It is not down on any map[^foo]; true places[^bar] never are.
[^foo]: A diagrammatic representation of an area of land or sea.
[^bar]: A particular position, point, or area in space; a location.
```
All footnotes will be displayed with a sequential number and rendered in the terminal like this:
## 2. Options
### 2.1 `:mode`
By default the `256` color scheme is used to render code block elements.
You can change this by specifying maximum number of colors to be `16` ANSI colors:
```ruby
TTY::Markdown.parse(markdown_string, mode: 16)
```
This feature may be handy when working in terminals with limited color support.
By default, **TTY::Markdown** detects your terminal color mode and adjusts output automatically.
### 2.2 `:theme`
Use the `:theme` option to change specific markdown element styles.
For example, to override styles for the `link` and `list` elements do:
```ruby
TTY::Markdown.parse(markdown_string, theme: {link: :magenta, list: %i[magenta bold]})
```
Here's a complete list of element names with corresponding styles:
| Name | Style |
|------------|-------------------------|
| `:comment` | `:bright_black` |
| `:em` | `:yellow` |
| `:header` | `%i[cyan bold]` |
| `:hr` | `:yellow` |
| `:image` | `:bright_black` |
| `:link` | `%i[yellow underline]` |
| `:list` | `:yellow` |
| `:note` | `:yellow` |
| `:quote` | `:yellow` |
| `:strong` | `%i[yellow bold]` |
| `:table` | `:yellow` |
Read [pastel documentation](https://github.com/piotrmurach/pastel#3-supported-colors) for all supported styles.
### 2.3 `:width`
You can easily control the maximum width of the output by using the `:width` key:
```ruby
TTY::Markdown.parse(markdown_string, width: 80)
```
By default the terminal screen width is used.
### 2.4 `:symbols`
By default formatting will include various Unicode symbols. You can switch to an included ASCII set and/or override individually with the `:symbols` key:
```ruby
TTY::Markdown.parse(markdown_string, symbols: :ascii)
TTY::Markdown.parse(markdown_string, symbols: {base: :ascii})
TTY::Markdown.parse(markdown_string, symbols: {override: {bullet: "x"}})
```
Here's a complete list of symbol names with corresponding ASCII and Unicode characters:
| Name | ASCII | Unicode |
|------------------|-------|---------|
| `:arrow` | `->` | `»` |
| `:bar` | `\|` | `┃` |
| `:bottom_center` | `+` | `┴` |
| `:bottom_left` | `+` | `└` |
| `:bottom_right` | `+` | `┘` |
| `:bracket_left` | `[` | `[` |
| `:bracket_right` | `]` | `]` |
| `:bullet` | `*` | `●` |
| `:diamond` | `*` | `◈` |
| `:hash` | `#` | `#` |
| `:hellip` | `...` | `…` |
| `:laquo` | `<<` | `«` |
| `:laquo_space` | `<< ` | `« ` |
| `:ldquo` | `"` | `“` |
| `:lsquo` | `"` | `‘` |
| `:line` | `-` | `─` |
| `:mdash` | `-` | `—` |
| `:mid_center` | `+` | `┼` |
| `:mid_left` | `+` | `├` |
| `:mid_right` | `+` | `┤` |
| `:ndash` | `-` | `-` |
| `:paren_left` | `(` | `(` |
| `:paren_right` | `)` | `)` |
| `:pipe` | `\|` | `│` |
| `:raquo` | `>>` | `»` |
| `:raquo_space` | ` >>` | ` »` |
| `:rdquo` | `"` | `”` |
| `:rsquo` | `"` | `’` |
| `:top_center` | `+` | `┬` |
| `:top_left` | `+` | `┌` |
| `:top_right` | `+` | `┐` |
### 2.5 `:indent`
By default any content apart from the main `h1` header is indented with `2` spaces. Use `:indent` to provide custom indent or no indent at all:
```ruby
TTY::Markdown.parse(markdown_string, indent: 0)
```
### 2.6 `:color`
You can control when to apply coloring to various document elements.
Valid values are `:never`, `:always` or `:auto`. By default `:auto` is used which auto detects if coloring can be applied.
For example, to always color content regardless of terminal support do:
```ruby
TTY::Markdown.parse(markdown_string, color: :always)
```
### 3. Command line tool
You can install [tty-markdown-cli](https://github.com/piotrmurach/tty-markdown-cli) to use `tty-markdown` executable in terminal:
```bash
$ tty-markdown README.md
```
