  • MINCE Is Not Complete[ly] EMACS

Codacy Badge GitHubCodeSize

Overview

  • MINCE is an Emacs-like text editor from Mark of the Unicorn, Inc.
    • Versions were available for many operating sysetms
      • CP/M‑80
      • CP/M‑68K
      • ST/GEMDOS
      • PC/DOS
      • RSX‑11
      • VAX/VMS
      • Wicat MCS
      • UNIX

Portable MINCE

  • "Portable MINCE" is real MINCE, plus:
    • CP/M system call translation
    • 8080/Z80 CPU emulation
      • 68000 support planned

Building

  • Required:

    • ANSI/ISO C compiler (gcc, clang, etc.)
    • POSIX cmp, env, and sh (Bourne shell)
    • GNU make

  • Optional:

    • Tcl expect and POSIX sed
      • Needed to override default terminal configuration (24 cols, 80 rows).

  • Review the Makefile for more information.

Roadmap

  • End-user configuration system, customizable via file or environment variables.
  • Avoid main input busywait/spin‑loop to reduce idle CPU usage.
  • Translation of line endings at run time (use dos2unix as a workaround).
  • Translation of PgUp / PgDn / Home / End / cursor control / arrow keys.
  • Build with GCC ‑fno‑common and reduce ‑Wall warnings.
  • Support crash recovery (by parsing mince.swp) in case of unclean exit.
  • Add support for external filters, such as hexadecimal mode (via xxd).
  • Support for automatic terminal resizing (by catching and handling SIGWINCH).
  • Allow building MINCE binaries with various extensions; produce verified/tested configurations.
  • Build and integrate Scribble, Pencil, and Crayon.
    • Automatic setup for ANSI/ASME Y14.1 (US) and ISO-216 (EU) paper types.
    • End‑user run time switching between different printer defintions.
    • Support for rendering (NEC, Epson, Diablo, etc.) proportional font printer output.
    • Conversion of Crayon output to PDF, PostScript, etc.
    • Automate Scribble formatting to (n)roff / groff, (X)HTML, TeX / LaTeX, etc. (utilizing Pandoc or similar tools for conversion).
  • Add Motorola 68000 CPU core for CP/M‑68K to support MINCE‑68K.
    • Automatically invoke MINCE‑68K version for large input files.
    • End-user configuration of default MINCE flavor (MINCE‑80 or MINCE‑68K).
  • User-configurable key bindings and mapping.
    • Allow user configuration without requiring full recompilation.
    • Normalize key bindings and mappings between MINCE flavors.
  • Support for RSX‑11, VMS, and OS/2 operating systems.
  • Create packages using NFPM / FPM, Homebrew tap / cask, pkgsrc, etc.
