QEmacs TODO list

Bugs

  • encode non printing characters in filenames and buffer names

  • change buffer list layout to increase buffer name width if needed

  • fix warning: int (*eb_printf_fun)(EditBuffer *b, const char *fmt, ...) = (void*)eb_printf;

  • fix crash bug on C-X C-B C-X C-F xxx RET

  • fix cursor positioning beyond end of screen

  • swap buffer names in compare-files

  • check file time and length when selecting a different buffer or running any command on the current buffer:

    • if a macro is running, stop it

    • prompt the user for (r) read, (i) ignore, (k) keep, (c) compare

    • if not modified since save, read in separate buffer and compare.

      • if difference before window start, mark and/or point, try and resync

    • if modified, modified version should be kept in a separate buffer. emacs behavior: You want to modify a buffer whose disk file has changed since you last read it in or saved it with this buffer.

      If you say y to go ahead and modify this buffer,
you risk ruining the work of whoever rewrote the file.
If you say r to revert, the contents of the buffer are refreshed
from the file on disk.
If you say n, the change you started to make will be aborted.

Usually, you should type r to get the latest version of the
file, then make the change again.

  • keep modified status when undoing past a buffer save command

Current work

  • in markdown mode, for code blocks without a language tag, try and determine the language from contents

  • kill eval result so it can be yanked where appropriate

  • add binding to convert the list of search matches into a multi-cursor (use C-\ ?)

  • odin: c-mode indentation does not work because of lack of semicolons

  • clang: colorize git conflict markers <<<<<<< HEAD } defaultCase = c;

======= } else

a450183c (Analyser: fix scope stack and init_checkers' array) if (!is_last) {

  • add cat mode where colorizer is chosen based on extension of filename between ==> xxx <==

  • start directory of make command should be the default directory of current buffer

  • delete bufed buffer when exiting bufed or clear flags on bufed invocation

  • should mark be a window variable instead of a buffer variable?

  • should tab-width be a window variable instead of or in addition to a buffer variable?

  • extra modes for drujensen/fib repo: es(escript), janet, k(K), p6, pony, ps1, pyx(cython), raku(rakudo), vb, zig detect flavors: ldc2?, bash, powershell, pypy, qb64, guile, sbcl

  • drag out of window should generate autorepeat scrolling requests

  • prevent mouse focus to window if searching

  • prevent mouse focus to window if minibuf active

  • only get tty clipboard contents on yank

  • only set tty clipboard contents if kill buffer changed during focus time

  • add script variable for clipboard support

  • add command line options for terminal features: backspace

  • add command line options for tracing

  • add command line options for color support

  • add script variable for terminal features: backspace

  • add script variable for tracing

  • add script variable for color support

  • from emacs:

    • set-background-color Set the background color of the selected frame to COLOR-NAME.
    • set-border-color Set the color of the border of the selected frame to COLOR-NAME.
    • set-cursor-color Set the text cursor color of the selected frame to COLOR-NAME.
    • set-foreground-color Set the foreground color of the selected frame to COLOR-NAME. These commands provide a multi-column completion window

  • test other terminals: Terminal.app, wezTerm, Visor, Guake, or Yakuake

  • check out Eternal Terminal: https://mistertea.github.io/EternalTerminal/

  • DEC SET 1036 ESC or Alt keys

  • do not abort macro on incremental search failure, just on final failure upon RET

  • show-date-and-time should distinguish between C-u and explicit number prefix

  • change accent input method: type accents before the character: when inserting an accent, insert a space before and do not move point when inserting a character before an accented space, replace

  • fix markdown command bindings

  • toggle long listing and column listing in dired buffers

  • keep a list of windows in EditBuffer

  • keep the last active window when detaching a buffer, just make it invisible.

    • easy if deleting the last window that shows the buffer
    • if changing the buffer for a window, if the new buffer has a pending window, use that
    • otherwise, create a new EditWindow with the same screen position for the new buffer.
    • alternative: keep previous window if changing the buffer so swapping back restores the position and mode

  • implement narrow_start̀ and narrow_end

  • add bindings for other editors: nano, vscode, emacs, qe, (vim ???)

  • load bindings corresponding to invokation command or cmdline option

  • add parametric syntax definitions (nanorc files).

  • implement a maximum macro length and abort macro learning mode if reached

  • integrate qscript

  • pass argval and argflags for most commands

  • add buffer commands and point update commands

  • add active_mark and active_region flags in window/buffer states

  • Many commands change their behavior when Transient Mark mode is in effect and the mark is active, by acting on the region instead of their usual default part of the buffer's text. Examples of such commands include M-;, flush-lines, keep-lines,

    • delete-blank-lines
    • query-replace, query-replace-regexp, replace-string, replace-regexp,
    • ispell, ispell-word -> ispell-region.
    • undo -> undo changes restricted to the current region
    • eval-region-or-buffer
    • isearch-forward.
    • ; or # or /: comment the block
    • \ add and or align \ line continuation characters (c like modes)
    • fill-paragraph
    • mark-paragraph extends the selection if already active

  • command aliases:

    • flush-lines -> delete-matching-lines.
    • keep-lines -> keep-matching-lines, delete-non-matching-lines.
    • how-many (aka count-matches)

  • goto-line should not set mark if mark is already active

  • whitespace-cleanup Command: Cleanup some blank problems in all buffer or at region. It usually applies to the whole buffer, but in transient mark mode when the mark is active, it applies to the region. It also applies to the region when it is not in transient mark mode, the mark is active and C-u was pressed just before calling whitespace-cleanup interactively.

  • comment-dwim Command: Call the comment command you want (Do What I Mean). If the region is active and transient-mark-mode is on, call comment-region (unless it only consists of comments, in which case it calls uncomment-region); in this case, prefix numeric argument ARG specifies how many characters to remove from each comment delimiter (so don't specify a prefix argument whose value is greater than the total length of the comment delimiters). Else, if the current line is empty, call comment-insert-comment-function if it is defined, otherwise insert a comment and indent it. Else, if a prefix ARG is specified, call comment-kill; in this case, prefix numeric argument ARG specifies on how many lines to kill the comments. Else, call comment-indent. You can configure comment-style to change the way regions are commented.

  • indent-for-tab-command(int ARG) Indent the current line or region, or insert a tab, as appropriate. This function either inserts a tab, or indents the current line, or performs symbol completion, depending on tab-always-indent. The function called to actually indent the line or insert a tab is given by the variable indent-line-function.

    If a prefix argument is given (ARG), after this function indents the current line or inserts a tab, it also rigidly indents the entire balanced expression which starts at the beginning of the current line, to reflect the current line's indentation.

    In most major modes, if point was in the current line's indentation, it is moved to the first non-whitespace character after indenting; otherwise it stays at the same position relative to the text.

    If transient-mark-mode is turned on and the region is active, this function instead calls indent-region. In this case, any prefix argument is ignored.

        int offset;
        // optional navigation data to accelerate buffer access:
