QEmacs TODO list

Documentation

• improve README.md
• rework documentation:

• document existing features
• make documentation available inside qemacs

• move documentation to markdown
• rewrite TODO.md file with more sections and explanations
• migrate coding-rules.html to markdown
• use cooked markdown mode for help
• add command qemacs-hello on C-h h : load hello file for charset tests
• add command qemacs-faq on C-h C-f
• add command qemacs-manual on C-h m
• help: data-directory, data-path ?
• add command documentation in describe-function
• add command documentation in describe-variable
• show memory stats in describe-buffer and about-qemacs
• add function to add entry in TODO.md

Core / Buffer / Input

• describe-key-briefly, local-set-key, etc should use a special input mode to read a string of keys via the minibuffer to remove the qe_key_process hack and use the same input behavior as emacs.
• in command specs, distinguish between interactive commands and non interactive functions
• use tabulation context for text_screen_width
• add method pointers in windows initialized from fallback chain
• remove redundant bindings along fallback chains
• share mmapped pages correctly
• check abort during long operations: bufferize input and check for ^G
• optional 64-bit offsets on 64-bit systems, use typedef for buffer offsets
• disable messages from commands if non-interactive (eg: set-variable)
• add custom memory handling functions.
• qe_realloc: typed and clear reallocated area
• use failsafe memory allocator and longjmp recover.
• move ungot_key to key_context
• splitting pages should fall on 32 bit boundaries (difficult)
• handle broken charset sequences across page boundaries
• allow recursive main loop, and remove input callbacks
• synced virtual buffers with restricted range
• unsynced virtual buffers with restricted range and specific mode/charset
• bfs: built in file system for embedded extensions and files Jasspa bfs is way too complicated, make simpler system
• notes
• tiny: remove extra features
• tiny: make a really small version
• use Cursors cursors in command dispatchers:

      struct QECursor {
          QEmacsState *qs;
          EditState *s;   /* points to the parent window */
          EditBuffer *b;
          int offset;
          // optional navigation data to accelerate buffer access:
          // getc(), peekc(), prevc()... etc.
      };
  

  an EditState would have an embedded QECursor that contains the buffer and offset an EditBuffer could also have an embedded QECursor with no EditState
