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 is that browser source was not 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.
