Paper downloader

Paper downloader is a simple chrome plugin which helps to download files from digital libraries with human readable file names. For example, when you download file from arxiv.org, you get something looks like "1234.5678.pdf". With this plugin, you get file named "%AUTHOR_NAME% - %PAPER_NAME%.pdf" instead.

How it works

Plugin adds it's own handler to "onclick" event on download link. When you click it, the file is downloaded to HTML5 Filesystem, and then it opens from thence.

Common functions for all sites are in common.js file. They are

• download_file(nice_name, url, callback), where nice_name is name which file will get, url is url for original file, and callback is function, which will be called after downloading. Note, that if file will be opened instead of saving (for PDF, for example), this function wiil not be called.

• process_link_click(authors, title, type, $link), where authors and title are strings, type is file extension, and $link is jQuery object for download link. This function adds "(loading)" to link text, and removes it after download. Probably, you should to use this function instead of call download_file directly, because in the second case you should manually to show user, that download is in progress.

How to write a script for another site

1. Write a script for your site. Probably, it has to add an onclick event handler to download links, and call process_link_click for them. Using jQuery for DOM traversing is recommended.

2. Modify manifest.json: add your site to permissions, and your site and script to content_scripts.

3. You can test it, using Load unpacked extension function in chrome. Read chrome extensions tutorial for more information.

4. (optional) Create a pull request with your script. In this case, file with your script should have name like script_yoursite.com.js. If you'll do it, your changes will appear in webstore after I'll check them.
