Won't work on Pinterest, Twitter, or GitHub (irony!) since these sites cut off inline JavaScript

Changes:

  • Added user name processing for more sites based on sites recognized by DW user tag
  • Stripped out paragraph formatting, took out From [Site Name] preface
  • Fixed a bug where the first two letters of DW titles were getting cut on non-entry pages
  • Escaped the @ character (primarily for Instagram), since @ is interpreted as the start of a user tag on DW

Issues/todo:

  • Getting usernames from on-page links (as opposed to URLs) doesn't work on sites other than AO3. Maybe I'm doing querySelector() all wrong. - Resolved. I saw where I went wrong and extracting usernames from page source works for the most part.
  • Redundancy in the getUserName() code should be reduced (by adding more functions?)
  • Profile pages could have more appropriate link text if getUserName() function returned an array
  • Code is far too long for bookmarklet format and keeps touching on the limit even with minification. Externalizing the code means it won't work on Facebook and Instagram, though. The code needs to be shortened & made less repetitive.

Deployment:

  • Ran the code through this minifier
  • Made the bookmarklet by putting the minified code through Bookmarklet Creator
  • I don't actually know how to code don't hurt me

This is so lovely.

I wish DW let us host a draggable button, tho. ( I know less about coding than you do).
