The [official documentation](http://shaarli.readthedocs.io/en/rtfd/) is generated from [Markdown](https://daringfireball.net/projects/markdown/syntax) documents in the `doc/md/` directory.

* If you create a new page, please link it from the new page (eg from the [Other links](https://github.com/shaarli/Shaarli/wiki#other-links) section.
* The wiki is a general documentation about Shaarli: usage, development, hacks, usage tricks, related links, projects. Try to keep it organized.
* The wiki will be synced to Shaarli's `doc/` directory on each release. Keep that in mind when reviewing the quality of your edits.
To edit the documentation, please edit the appropriate `doc/md/*.md` files (and optionally `make htmlpages` to preview changes to HTML files). Then submit your changes as a Pull Request.

## About
### Shaarli community fork
This friendly fork is maintained by the Shaarli community at https://github.com/shaarli/Shaarli
This is a community fork of the original [Shaarli](https://github.com/sebsauvage/Shaarli/) project by [Sébastien Sauvage](http://sebsauvage.net/).
The original project is currently unmaintained, and the developer [has informed us](https://github.com/sebsauvage/Shaarli/issues/191)
that he would have no time to work on Shaarli in the near future.
The Shaarli community has carried on the work to provide
[many patches](https://github.com/shaarli/Shaarli/compare/sebsauvage:master...master)
for [bug fixes and enhancements](https://github.com/shaarli/Shaarli/issues?q=is%3Aclosed+)
in this repository, and will keep maintaining the project for the foreseeable future, while keeping Shaarli simple and efficient.
### Contributing
If you'd like to help, please:
- have a look at the open [issues](https://github.com/shaarli/Shaarli/issues)
and [pull requests](https://github.com/shaarli/Shaarli/pulls)
- feel free to report bugs (feedback is much appreciated)
- suggest new features and improvements to both code and [documentation](https://github.com/shaarli/Shaarli/wiki)
- propose solutions to existing problems
- submit pull requests :-)

*
* Settings:
* - translation.mode:
* - auto: use default setting (PHP implementation)
* - php: use PHP implementation
* - gettext: use gettext wrapper
* - translation.language:
* - auto: use autoLocale() and the language change according to user HTTP headers

You can easily retrieve your links, even with thousands of them, using the internal search engine, or search through tags (e.g. this Shaare is tagged with `shaarli` and `help`).
Hashtags such as #shaarli #help are also supported.
You can also filter the available [RSS feed](/feed/atom) and picture wall by tag or plaintext search.
We hope that you will enjoy using Shaarli, maintained with ❤️ by the community!

* Data storage for links.
*
* This object behaves like an associative array.
*
* Example:
* $myLinks = new LinkDB();
* echo $myLinks[350]['title'];
* foreach ($myLinks as $link)
* echo $link['title'].' at url '.$link['url'].'; description:'.$link['description'];
*
* Available keys:
* - id: primary key, incremental integer identifier (persistent)
* - description: description of the entry
* - created: creation date of this entry, DateTime object.
* - updated: last modification date of this entry, DateTime object.
* - private: Is this link private? 0=no, other value=yes
* - tags: tags attached to this entry (separated by spaces)
* - title Title of the link
* - url URL of the link. Used for displayable links.
* Can be absolute or relative in the database but the relative links
* will be converted to absolute ones in templates.
* - real_url Raw URL in stored in the DB (absolute or relative).
* - shorturl Permalink smallhash
*
* Implements 3 interfaces:
* - ArrayAccess: behaves like an associative array;
* - Countable: there is a count() method;
* - Iterator: usable in foreach () loops.
*
* ID mechanism:
* ArrayAccess is implemented in a way that will allow to access a link
* with the unique identifier ID directly with $link[ID].
* Note that it's not the real key of the link array attribute.
* This mechanism is in place to have persistent link IDs,
* even though the internal array is reordered by date.
* Example:
* - DB: link #1 (2010-01-01) link #2 (2016-01-01)
* - Order: #2 #1
* - Import links containing: link #3 (2013-01-01)
* - New DB: link #1 (2010-01-01) link #2 (2016-01-01) link #3 (2013-01-01)
* - Real order: #2 #3 #1
