# Features

- Supports Markdown ATX-style headers. Example: `# Header`.
    - Does not support header suffixes. Example: `# Header #`.
    - Does not support header previxes without spaces. Example: `#Header`.
- Prepends table of contents to Markdown documents that don't have table of contents.
- Replaces/updates Markdown documents that have existing table of contents.

# Requirements

0. A UNIX-based system.
0. [MRI 2.x.x](http://www.ruby-lang.org).

# Setup

For a secure install, type the following (recommended):

    gem cert --add <(curl -Ls http://www.my-website.com/gem-public.pem)
    gem install tocer --trust-policy MediumSecurity

NOTE: A HighSecurity trust policy would be best but MediumSecurity enables signed gem verification while
allowing the installation of unsigned dependencies since they are beyond the scope of this gem.

For an insecure install, type the following (not recommended):

    gem install tocer

# Usage

From the command line, type: `tocer help`

    tocer -e, [--edit]               # Edit Tocer settings in default editor.
    tocer -g, [--generate=GENERATE]  # Generate table of contents.
    tocer -h, [--help=HELP]          # Show this message or get help for a command.
    tocer -v, [--version]            # Show Tocer version.

To add Tocer support, add the following at the correct position within your Markdown files:

```
<!-- Tocer[start]: Auto-generated, don't remove. -->
<!-- Tocer[finish]: Auto-generated, don't remove. -->
```

Alternatively, you can run `tocer -g <file_path>` on a file that does not have Tocer support and it will prepend the above
to your file, complete with an auto-generated table of contents.

In the case that Tocer has already auto-generated a table of contents for a Markdown file, the existing table of
contents has become stale, or placement of the table of contents has changed you can re-run Tocer on that file to auto-
update it with new table of contents.

# Tests

To test, run:

    bundle exec rake
