Judges’ remarks:

This is not your grandmother’s 👵 emacs(1) 🤓, nor is it as limited as ed(1), eh (🇨🇦)?

The source (and of this program) has fun with an UTF-8 conforming accent, in a manor of speaking 😉.

TL;DR - to exit type Q or press CTRL+C.

As mentioned in the COMMANDS section of prog.html, try these commands:

    | Key cmd  | Action                                                     |
    |----------|------------------------------------------------------------|
    | h j k l  | Left, down, up, right cursor movement                      |
    | H J K L  | Page top, page down, page up, page bottom                  |
    | b w      | Word left, word right                                      |
    | |        | Goto column (count) of physical line                       |
    | /ERE     | Find first occurrence of ERE pattern after the cursor      |
    | n        | Find next occurrence of ERE                                |
    | G        | Goto line (count) number; 1G top of file, G bottom         |
    | \        | Toggle text selection                                      |
    | d motion | Delete text selection or region given by motion            |
    | y motion | Yank (copy) text selection or region given by motion       |
    | P        | Paste last deleted or yanked text region before the cursor |
    | i        | Insert text mode before cursor, ESC or CTRL+C ends insert  |
    | u        | Toggle undo of last edit                                   |
    | x        | Delete character after the cursor, i.e., dl                |
    | W        | Write buffer to file                                       |
    | Q        | Quit                                                       |
    | CTRL+C   | Quit                                                       |

Author’s remarks:

Building

Simply type make to build. There are two macros that can be customised:

• BUF to set the buffer size; default 128KB.

• MODE to set the file creation mode; default 0600.

What’s Interesting

• This is an update with bug fixes of a previous IOCCC winner, with permission of the author.

• This entry requires Curses. Some Linux might require NCurses built with wide character support, -lncursesw.

• The source is UTF-8. When are é ë ê è not same as e?

• The documentation is found in prog.html.

• prog can view its own source.

• A regression test suite is available on demand. The test suite requires tic(1) to build the specialised test terminal entry.

• Original unobfuscated more fully featured source available (search/replace, pipe-filter selection, markers, insert file, edit buffer grows, literal character input, multi undo/redo). See full version.

• The iocccsize(1) tool only counts bytes, not characters, i.e,. UTF-8 multibyte characters such that some characters cost 2, 3, or 4 bytes, thus penalising UTF-8 entries.

  UTF-8 demands equal rights and respect as real characters! The dominance of slim ASCII must end! We are the UTF-8 People’s Front for Freedom, Equality, and Brotherhood (oh that’s been used already) - We are the UTF-8 Countless Tourist Defence Farce for One Voice, One World, One Character Set.

Furthermore:

• Refactor page framing to address original issue of scrolling and paging up/down when the file contains long lines.

• CTRL+C will exit insert mode as with vi(1); CTRL+C will also quit, unlike vi(1), for those who cannot find Q.

• Add extended regular expression forward search with buffer wrap-around.

• Add text selection with delete (cut), yank (copy), and put (paste).

• Add delete (cut), yank (copy) with motion.

• Replace start/end of line with goto-column command.

• Add counts for motion commands, delete, and put.

• Replace top/end of file with goto-line command.

• Fix word left to behave like vi(1).

• Add basic UTF-8 support.
