Check out this amazing open-source text editor:
It’s written in Lua and it’s very easily extendable. Its architecture is elegant and minimalistic, qualities it shares with Lua.
Thanks, an interesting alternative to Notepad++ for non-Windows users.
I still prefer Notepad++ in Windows, which already features many plugins, plus a full-powered Lua 5.3 plugin, with binding to the Scintilla API to control almost all aspects of the editor, that also supports more extended regular expressions (notably ECMAScript regexp, but still not those in PCRE or Perl style). Only one bad thing about Notepad++ is that it has only two editor panels presetned side by side, instead of generic tabs.)
and Notepad++ can load very large files that RxiLite cannot. Its Scintilla API is also much very fast for complex operations and for syntax coloring, and scrolling of long texts.
(In the past, Notepad++ was not very safe and the undo-history could be corrupted by large search-replace operations: this seems to have been fixed when Notepad++ abandonned the basic Microsoft Rich-text component for the new Scintilla widget, which handles buffers and styling/coloring much more safely and much faster for loading buffers).
