What does it do?

Displays and Pages a document which is sectioned using a special heading pattern.

Preparing the Document

Your document should include headings which are generally comments which follow a pattern.

Currently, the default pattern is:

Document	Main Heading	Sub Heading
Text	## Main Heading	### Sub Heading
Coding	/** Main Heading	/* Sub Heading

Note that the /* style comment is a block comment. The heading will only extend to the end of the line.

Highlighed Code Lines

You can mark one or more lines for highlighting by ending it with a special marker. Typically it’s a comment marker with an exclamation mark (!) at the end.

For example:

var newInfo = null;		//!

The line number will appear hightlighted.

Viewing the Document

Naturally, you will first need to open the document. You can open a document from the local file system or from the Internet.

Operation	Menu	Keyboard Shortcut
Open a Local File	Open …	⌘O or ⌃O
Open a URL	Open URL …	⌘⇧O or ⌃⇧O

Navigating the Document

The headings will appear on the left.

By default, the code samples are syntax-highlighted (except, of course, for Text files). If you need to copy some of the code, this will interfere with your copy.

To view the unhighlighted version, you can either:

• option/alt-click on the title
• Turn off the Highlight Syntax button
• Click on the Raw button near the content.

Full(ish) Screen

On the control bar, there is a button Full Screen. This will remove all the bits around the main content.

If you want true full screen, you will need to use the operating system’s full screen feature as well.

• You can navigate through the pages using the ← or → keys.
• You can go to the first or last page using the ↑ or ↓ keus.
• You can get back to normal by pressing the Esc key.

Preferences

Document Pager will create a folder in the user’s home directory called .document-pager. It includes:

File	Usage
languages.json	Additional Language Settings
files.json	A list of last open files
state.json	Other state values

as well as some others to remember what you’ve done.

Additional Headings

If you want to add your own heading markers, you should add them to the languages.json file using the following pattern:

{
	"language": {
		"extensions": ["…"],
		"breaks" { "major": ["…"], "minor": ["…"] }
	}
}

You can omit any of the sub sections, and you can have multiple values inside the square brackets.

As you might have guessed from the name, the file is in JSON format. JSON is very fussy, so it’s easy to make a mistake.

Default Language Settings

Here are the default language settings:

{
	"javascript": {
		"extensions": ["js","javascript"],
		"breaks": { "major": ["/**"], "minor": ["/*"]},
		"highlight": "//!"
	},
	"php": {
		"extensions": ["php"],
		"breaks": { "major": ["/**","/*:"], "minor": ["/*"] },
		"highlight": "//!"
	},
	"python": {
		"extensions": ["py"],
		"breaks": { "major": ["#:"], "minor": ["#::"] },
		"highlight": "#!"
	},
	"sql": {
		"extensions": ["sql"],
		"breaks": { "major": ["/**"], "minor": ["/*"] },
		"highlight": "--!"
	},
	"css": {
		"extensions": ["css"],
		"breaks": { "major": ["/**"], "minor": ["/*"] },
		"highlight": "/*!*/"
	},
	"markdown": {
		"extensions": ["md","markdown","mds"],
		"breaks": { "major": ["##"]}
	},
	"text": {
		"extensions": ["txt","text","*"],
		"breaks": { "major": ["#"], "minor": ["##"] },
		"highlight": "#!"
	}
}

These default settings are not in the languages.json file, but are built-in.

MarkDown Documents

You can also page through MarkDown documents. Here the ## heading is used for paging.

Markdown files are recognised by the following extensions: .md, .markdown and .mds, or others if you’re prepared to add your own to the languages.json file.

The .mds extension is for a future enhancement.

Special Headings

Markdown headings can take the following non-standard format:

	##id.class

This generates HTML in the following format:

	<h2 id="…" class="…"> … </h2>

The id and class are both optional

Other markdown editors will not recognise this, and so it will appear as a paragraph.

Images

If you include images, you can either use absolute references to them or you can include images relative to the document itself.

It would make sense to make a special folder for this, but it’s not required.

Custom Styles

You can add your own custom MarkDown styles using a CSS file in the same location with the same name:

For example:

test.md
test.css

Sample Folder Structure

For practical purposes, you might have a folder structure which includes a style sheet and a folder for images:

sample.md
sample.css
images/
