  10. // This script was developed in Vivaldi, running on Mac OS High Sierra. It has been tested in various Chrome and Gecko-based browsers. It has only been minimally tested on Windows, however. It should work, but please report any issues.
  11. // It does not work in Safari because Safari does not allow local directories to be browsed.
  12.  
  13. // NOTE: By default, Greasemonkey and Tampermonkey will not run scripts on file:/// urls, so for this script to work, you will have to enable it first.
  14. // For Greasemonkey, open about:config and change greasemonkey.fileIsGreaseable to true.
  15. // For Tampermonkey, go to Chrome extension page, and tick the 'Allow access to file URLs' checkbox at the Tampermonkey extension section.

  17. // CHANGELOG:
  18.  
  19. // v. 2.0.2
  20. // Various fixes suggested by "Zorg":
  21. // Dark mode now ignores html files (and media files), but inverts all plain text files. This solution is not perfect: there is a flash of inverted content when navigating from an html or media file to a non-html or media file; will look for a fix.
  22. // Fixed display of non-Latin characters in sidebar header.
  23. // Add support for Linux "home" directory for user profile shortcuts (hopefully).
  24. // Made entire up directory button clickable.
  25.  
  26. // v. 2.0.1
  27. // Fixed wonky font preview scaling.
  28.  
  29. // v. 2.0
  30. // NEW! Not just for local directories anymore! Added support for *many* server-generated directory index pages (It's impossible to check every server configuration, needless to say, so it might not work in every case; let me know if you encounter problems.// NEW! Preview font files (otf, ttf, woff, woff2). Great for designers: preview fonts without installing them. Hint: To install previewed fonts, just type Cmd/Ctrl + O or right-click the link and save it to your fonts folder. Font preview pane is content-editable.
  31. // NEW! Preview font files (otf, ttf, woff, woff2). Great for designers: preview fonts without installing them. Hint: To install previewed fonts, just type Cmd/Ctrl + Shift + O or right-click the link and save it to your fonts folder. Font preview pane is content-editable.
  32. // Added: Now use the Left and Right arrow keys to navigate through images and fonts in a folder, skipping other files. Use up and down arrow keys to navigate all files normally.
  33. // Added: Basic dark mode user setting.
  34. // Added: Wrap-around keyboard navigation.
  35. // Added: Cmd/Ctr-D to toggle details.
  36. // Added: Cmd/Ctr-Shift-. and Cmd/Ctr-Shift-, to scale font previews text size.
  37. // Changed: Moved dynamically-added in-line styles to appended stylesheet.
  38. // Changed: Extensive refactoring of code for better separation of concerns. (More needs to be done.... Sigh.)
  39. // Removed: ScrollIntoView for Grid views. Scrolling didn't work reliably when the sidebar was also being scrolled. Will restore when bug fixed.
  40. // Many small bug fixes.
  41.  
  42. // v. 1.4
  43. // Added: Initial support for Firefox. Tested in Firefox 59, Waterfox 56.
  44. // Changed: Use SVG for menu icons
  45. // Changed: Code cleanup, reorganization
  46. // Renamed script to "Supercharged Local Directory File Browser"
  47.  
  48. // v. 1.3
  49. // Fixed: Keyboard navigation of ignored or invisible items fails if "Hide Invisibles" is toggled off after loading a directory.
  50. // Added: Also hide ignored files if "Hide Invisibles" is checked.
  51. // Added: Content reload button.
  52. // Changed: Reorganized settings to reduce confusion about how ignored files are treated.
  53.  
  54. // v. 1.2
  55. // Click to show menus instead of hover.
  56. // Added Cmd/Crl+Shift+O keybinding to open selected item in new window
  57. // Arrow navigation bugfixes
  58.  
  59. // TO-DO:
  60. // Select two items for split pane view?
  61. // if invisible item is selected when "hide invisibles" is unchecked, select nearest previous visible item when hide invisible is checked agagin?
