Fade time can be configurable separately for these 3 cases.
  • Fade-in; Received a non-empty text when text was empty.
  • Fade-out; Received an empty text when text was not empty.
  • Cross-fade; Receiving a non-empty text when text was not empty.
Slide feature is currently experimental.
  • When the text is updated, the old text will move up to disappear and the new text will rise from the bottom.
Why no package for Windows
Background I started to develop this plugin was that the browser source was not so stable on Linux at that time. Freetype2 text does not have configurable outline width. Pango text is also a good plugin but it takes 1 to 2 seconds to reload updated text file. I started to look into the source code of pango text and noticed there is a markup feature provided by the library pango.
Unfortunately, pango is developed mainly for Linux and it depends glib, which depends a lot of libraries. On Linux and macOS, it is easy to install these libraries, it takes just a few commands. However, there are no simple step to install these libraries and need to build one by one. I tried to build them on Windows but could not achieve so far.
