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.
