Most important news is the new modeline and support for building and running without Ncurses, or termcap/terminfo!

Packages for Debian 10, and compatible Ubuntu releases, available at https://deb.troglobit.com/

Changes

  • Support for building without termcap/terminfo/ncurses. This feature will be welcome for embedded systems, and others who cannot, or do not want to, bundle the complete ncurses
  • Support for opening .gz text files, as read-only
  • Support for C-h t to access the Mg tutorial
  • Support for C-h q to toggle *quick* help buffer
  • New default key bindings for cursor movement, from GNU Emacs:
    • C-up backward-paragraph
    • C-down forward-paragraph
    • C-left backward-word, also M-left
    • C-right forward-word, also M-right
    • C-PgUp beginning-of-buffer
    • C-PgDn end-of-buffer
  • Sync with OpenBSD:
    • Update all $OpenBSD: id$ strings
    • Fix -Wshadow warnings
    • Fix missing return value checks
  • Modeline changes to mimic GNU Emacs
    • Drop Mg:, similar to yur3i/mg/commit/@84ce23b
    • Use space instead of dash - as separator, same as @yur3i
    • Hard code std encoding and UNIX end-of-line mode
    • Show (line,column) and place before buffer modes
    • Upper case for each mode listed
    • New display-time-mode, toggle current time in modeline
  • Enable column-number-mode by default
  • Add new internal mglog_misc() debug API
  • Clear status line after killing/switching buffer by name, fixes lingering prompt after said action
  • Rename Debian package: mg -> mg2a, provides mg

Fixes

  • Check return value from all fopen() calls in internal log API
  • Duplicate definitions of global variables in def.h, found by GCC-10. Patched by Ulrich Mueller of Gentoo, via OpenBSD and Han Boetes
  • Avoid NULL deref in regexec when searching for empty lines, from OpenBSD by Hiltjo Posthuma
  • Prevent segfault with query-replace-regex replacing ^, from OpenBSD by Mark Williamson
  • Avoid running out of memory with query-replace-regex ^, from OpenBSD by Mark Williamson
