This package is still work in progress; it may have breaking change(s) without notice.

Currently I'm targeting nim-mode's (Nim language's major-mode).

Probably most easiest way to use this package is using el-get.

;; el-get-sources
(:name flyhigh
      :type github
      :depends (dash deferred) ; might need other package(s)
      :pkgname "yuutayamada/flyhigh"
      :minimum-emacs-version "26")

• this package should not block user input; do tasks asynchronously (partially done using deferred.el)
• example (living example is flyhigh-nimsuggest)
• trigger highlight by
  • (1) when the cursor is moved to outside of invisible window
    • this just needs to refresh highlight inside of visible window
      • provide dedicated idle timer variable (this is different usage against (2))
    • if there are uncompleted highlight from previous query, we should use cached highlight and don't make new query.
  • (2) after change (after-change-functions hook)
    • provide dedicated idle timer variable for this, but this timer should be longer than other packages' idle timer like flycheck, and company
  • [ ]
• be highlighted from visible window
• highlight invisible overlays
• keep used overlay(s) until:
  • buffer change
    • but removal of overlay(s) should be from visible overlays
      • and should be kept invisible overlays until it become visible
      • but during idle time, incorrect invisible overlays should be fixed asynchronously
  • [ ]
• stable APIs
• register MELPA (but currently this package is too immature)
• make some tests using faceup.el
• document
