## Install SpiffyTitles
- `git clone https://github.com/oddluck/limnoria-plugins.git`
- `cd limnoria-plugins`
- `cp -r SpiffyTitles ~/your_bot_directory/plugins`
- `cd ~/your_bot_directory/plugins/SpiffyTitles`
- `pip install -r requirements.txt --user --upgrade`

You should `!unload Web` and any other plugins that show link titles for best results

Load SpiffyTitles:
    
`!load SpiffyTitles`

Pro Tip: Observe the logs when loading the plugin and afterwards to see if there are any errors.

You can increase the verbosity of the logging in SpiffyTitles by issuing the following command:


`!config supybot.log.level DEBUG`


## On-Demand Titles
You can retrieve titles on demand using the `t` command. If something goes wrong, `badLinkText`
will be sent instead of the link title.

## Available Options

### Note
Almost all of the below options can be customized per-channel.

Example:

`!config channel ##example-channel-one supybot.plugins.SpiffyTitles.default.template "^ {{title}}"`

`!config channel ##example-channel-two supybot.plugins.SpiffyTitles.default.template ":: {{title}}"`

This means that you can change whether a handler is enabled, or what the template looks like for any channel.

### Default handler

`default.enabled` - Whether to show additional information about links that aren't handled elsewhere. You'd really only want to disable this if all of the other handlers were enabled.

`default.userAgents` - A comma separated list of strings of user agents randomly chosen when requesting.

`default.language` - Accept-Language header string. https://tools.ietf.org/html/rfc7231#section-5.3.5

`default.template` - This is the template used when showing the title of a link.

Default value: `^ {{title}}`

Example output:

`^ Google.com`

Default value: `{% if type %}[{{type}}] {% endif %}{% if size %}({{size}}){% endif %}`

`whitelistDomainPattern` - ignore any link without a domain matching this pattern. Default value: `""`

### About white/black lists
- Channel names must be in lowercase
- If `channelWhitelist` and `channelBlacklist` are empty, then titles will be displayed in every channel
- If `channelBlacklist` has #foo, then titles will be displayed in every channel except #foo
- If `channelWhitelist` has #foo then `channelBlacklist` will be ignored

### Examples

### Show titles in every channel except #foo

`!config supybot.plugins.SpiffyTitles.channelBlacklist #foo`

### Only show titles in #bar

`!config supybot.plugins.SpiffyTitles.channelWhitelist #bar`

### Only show titles in #baz and #bar

`!config supybot.plugins.SpiffyTitles.channelWhitelist #baz,#bar`

### Remove channel whitelist

`!config supybot.plugins.SpiffyTitles.channelWhitelist ""`

### Pro Tip

You can ignore domains that you know aren't websites. This prevents a request from being made at all.

### Examples

Ignore all links with the domain `buzzfeed.com`

`!config supybot.plugins.SpiffyTitles.ignoredDomainPattern (buzzfeed\.com)`

Ignore `*.tk` and `buzzfeed.com`

`!config supybot.plugins.SpiffyTitles.ignoredDomainPattern (\.tk|buzzfeed\.com)`

Ignore all links except youtube, imgur, and reddit

`!config supybot.plugins.SpiffyTitles.whitelistDomainPattern /(reddit\.com|youtube\.com|youtu\.be|imgur\.com)/`

Ignore any message that contains "[tw]".

`!config supybot.plugins.SpiffyTitles.linkMessageIgnorePattern "/\[tw\]/"`

Ignore any link which results in a title matching a pattern.

`!config channel #example supybot.plugins.SpiffyTitles.ignoredTitlePattern m/^\^ Google$|- Google Search$|^\^ Google Maps$|^\^ Imgur: The most awesome images on the Internet$|^\^ Pastebin \| IRCCloud|^\^ Instagram|^\^ Urban Dictionary:|– Wikipedia$|- Wikipedia, the free encyclopedia$|- Wiktionary$| - RationalWiki$|^\^ Meet Google Drive|- Wikia$|^\^ Imgur$|^\^ Google Trends|^\^ reactiongifs/`
