At the moment are supported [BibTeX](http://en.wikipedia.org/wiki/BibTeX "BibTeX"), [CSL](http://citationstyles.org/ "CSL") and [RIS](http://en.wikipedia.org/wiki/RIS_(file_format) "RIS"). Installation ------------ [](#installation) ### Via [composer](http://getcomposer.org/ "composer") [](#via-composer) Add to the `composer.json` the `require` key and run composer install. ``` "require" : { "lakshay/converter": "dev-master" } ``` ### Other [](#other) Make sure you are using a [PSR-2](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-2-coding-style-guide.md "PSR-2")compatible autoloader. Usage ----- [](#usage) To convert form one standard to an other: ``` // include the composer autoloader require __DIR__ . '/vendor/autoload.php'; use Lakshay\Converter\Converter; use Lakshay\Converter\Standard\RIS\RIS; use Lakshay\Converter\Standard\BibTeX\BibTeX; use Lakshay\Converter\Standard\CSL\CSL; $converter = new Converter(); // your input RIS data $data = 'TY - JOUR TI - Die Grundlage der allgemeinen Relativitätstheorie AU - Einstein, Albert PY - 1916 SP - 769 EP - 822 JO - Annalen der Physik VL - 49 ER - '; // convert to bibTeX $bibTeX = $converter->convert(new RIS($data), new BibTeX()); /** * $bibTeX now has the following value: * * @article{article, * author = {Einstein, Albert}, * year = {1916}, * pages = {769-822}, * title = {Die Grundlage der allgemeinen Relativitätstheorie}, * volume = {49} * } */ // or convert bibTeX to csl $csl = $converter->convert(new BibTeX($bibTeX), new CSL()); /** * $csl now has the following value (a UTF-8 encoded json string): * * [ * { * "type":"article", * "author":[{ * "family":"Einstein", * "given":"Albert" * }], * "issued":[{ * "year":"1916" * }], * "page":"769-822", * "page-first":"769", * "citation-label":"article", * "title":"Die Grundlage der allgemeinen Relativit\u00e4tstheorie" * } * ] */ ``` Limitations ----------- [](#limitations) The built-in BibTeX converter has the following limitations: - Non-UTF-8 strings are converted to UTF-8 - LaTeX escape sequences are converted to UTF-8 characters - Enclosing braces are discarded. (Neither CSL nor RIS support explicit capitalisation.) Adding a standard ----------------- [](#adding-a-standard) To implement a new standard is quite simple: 1. Create a copy of the folder **src/Lakshay/Converter/Standard/Template** 2. Change the name to the new standard. 3. Rename also the **Template.php** file to the name of the standard 4. Replace every occurence of **Template** in the files **Creator.php**, **Parser.php** and **Template.php** with the name of the new standard. 5. Implement the methods **create** and **retrieve** in **Creator.php** 6. Implement the methods **parse** and **retrieve** in **Parser.php** 7. Don't forget to write your PHPUnit tests and follow the [PSR-2](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-2-coding-style-guide.md "PSR-2") coding standard Tests ----- [](#tests) Converter depends on PHPUnit. Ensure that your dependencies are up to date by running `composer update` then call `vendor\bin\phpunit tests` to run all the tests. ### Health Score 24 — LowBetter than 31% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity4 Limited adoption so far Community12 Small or concentrated contributor base Maturity52 Maturing project, gaining track record Bus Factor2 2 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
