LEA is a Lightweight Editor for Ada

Web site: http://l-e-a.sf.net/
Source repository #1: https://sf.net/p/l-e-a/code/HEAD/tree/
Source repository #2: https://github.com/zertovitch/lea

Changes since last announcement here: 

  - Added auto insert feature: e.g. typing `(` inserts `)`.
  - Added color theme Solarized Light.
  - Added a "stealth mode" in which LEA doesn't leave
       traces in the registry.
  - Editor adds `--  ` if the cursor is within a comment when the Return key
       is pressed (consequence: a comment is split into two comments).
  - If the cursor is within a string literal when the Return key is
       pressed, the string literal is split into two valid string
       literals with a `&` between them.
  - Added unhandled exception information to message list
  - Tabs with the various file names
  - LEA doesn't write scilexer.dll as a file; thus, it runs as 
       a portable application (in the sense: you can run it from a
       read-only drive directly, without installation)
  - Added a Build & Run button (for the HAC compiler).

Features:
  - multi-document
  - multiple undo's & redo's
  - multi-line & multi-point edit, rectangular selections
  - color themes, easy to switch
  - duplication of lines and selections
  - syntax highlighting
  - parenthesis matching
  - bookmarks

Currently available on Windows.
Gtk or other implementations are possible: the LEA_Common[.*] packages
are pure Ada, as well as HAC.

Enjoy!
