olinkcheck

A tool to find broken URLs in text-based files.

Supported Formats

olinkcheck currently supports:

• Markdown
• Plaintext
• S Expressions
• YAML
• HTML
• Any combination of these (see Library)

Usage

CLI

$ olinkcheck [--annotate] [--exclude-list=EXCLUDE-LIST] [--verbose]
FORMAT FILE

For example,

$ olinkcheck md file.md

This will list all the web links found in the file, ping them and report their HTTP status. FILE can be a directory, in which case all the files in that directory are searched recursively for files matching the corresponding extension.

The following options are valid for FORMAT:

• md for Markdown
• txt for Plaintext
• md_with_yaml for Markdown containing a YAML header
• html_with_yaml for Markdown containing a YAML header and HTML body

The --verbose flag reports links that have status 200 OK as well.
The --annotate flag indicates the broken links in the file itself.

Library

Example usage in utop:

# #require "olinkcheck";;
# Olinkcheck.Markdown.extract_links "##title [url](http://www.google.com)";;
- : string list = ["http://www.google.com"]
# Olinkcheck.Link.status "http://www.google.com";;
- : int * string = (200, "OK")

To handle files with multiple formats, you can use define a ParserPair with separate and join functions to separate the text into two different formats, and use MakePairParser to get a Parser to handle it. A pair parser handling YAML headers in Markdown, with some fields in the YAML also containing Markdown has been implemented (see YamlMdPair and YamlMdParser).
