Basic stuff

crash bug on johnmacfarlane.net/texmath.xhtml

abbreviate lines in file completion list popup

wrap long lines past line numbers column

tty_put_char should convert charsets

current path in compile set to current buffer path

avoid error in new file

check file permissions.

add custom memory handling functions.

use failsafe memory allocator and longjmp recover.

redefine KEY_Fx to make them sequential

move ungot_key to key_context

use trick for entering spaces in filename prompts without completion

static init_call stuff ?

add default for new buffer creation, set that to utf8

splitting pages should fall on 32 bit boundaries (difficult)

handle broken charset sequences across page boundaries

add command help/description in declarations

make command declaration macros standalone

expression evaluator

allow recursive main loop, and remove input callbacks

fix column computation based on display properties:

(variable pitch, tabs, ^x and \uxxxx stuff – emacs behaviour) ?

undo: limit size of undo buffers

undo: add undo records for styles, modes…

undo: disable undo for archive parse and uncompress phases

synced virtual buffers with restricted range

unsynced virtual buffers with restricted range and specific mode/charset

spell checker

printing support

bfs: built in file system for embedded extensions and files

Jasspa bfs is way too complicated, make simpler system

session history

notes

C-x x next-buffer ??? Move to the next buffer.

abbreviation mode

qe_realloc -> typed and clear reallocated area

timers for esc key disambiguation

ftp: / http: support

set-auto-mode: reselect best mode

set-next-mode: select nth best mode

handle \r\n as a minor charset mode

eb_printf return value

do_fill_paragraph for wide char buffers

add auto close buffer flag (for list mode)

add raw|none|binary encoding

simplify paragraph stuff with eb_is_blank_line

show-bindings fails if binding is redefined (eg: M-q)

set-fill-column

fill-column variable

Moving / Editing

ESC left/right -> descrease/increase-width in hex / binary / unihex modes

remote editing

blink-and-insert on ) } ] >

fix scroll up/down to move point if already at end

move by paragraph on M-[ and M-]

scroll horizontally on M-{ and M-}

scroll up/down with argument should scroll by screen row.

simplify C-z A-z accordingly

accented letters on OS/X

combining unicode glyphs produce bogus cursor positions

example: V M-’ this problem occurs if no combined glyph exists. qemacs does not take into account combination performed by the terminal. Terminal glyph width of 0 should be supported.

deal with accents in filenames (OS/X uses separate utf8 accents)

stats command for word count and mode specific stats

256 color mode

auto-fill-mode

auto-revert-mode, global-auto-revert-mode, auto-revert-tail-mode

extend hex mode to support 16,32,64 words as little and big endian

rectangular regions, cut/paste

transpose-chars broken except at end of line

transpose-words broken except at beginning of line

mark-paragraph -> M-h

combine accents with M-` M-’ M-” M-^

inserting accents should combine with previous char

Windowing / Display

window scrolling not emulated in tty (check ^Z in recursive eps)

multiple frames

lingering windows

cursor not found on doc/256colors.raw if truncate-lines=1

enlarge-window-interactively

enlarge-window-horizontally

enlarge-window

tab cursor displayed size

improve speed of text renderer / improve truncate mode

merge some good parts with CSS renderer ?. Suppress CRC hack (not reliable).

display alternate cursor in non active column in hex mode.

fix crash bug on fragments longer than MAX_SCREEN_WIDTH.

vertical scroll bar

menu / context-menu / toolbars / dialogs

improve layout scheme for better scalability.

scrolling by window size should position cursor differently

emulation mode to use line-drawing characters for window borders

Clean window deletion mess:

avoid problems with popups (kill_buffer, delete_window, split_window)

detach window from tree and keep attached to buffer if last

detach window from tree and put in delayed free tree otherwise

edit_close(s) do_delete_window(s) bufed_select(s) if vertical split dired_select(s) if vertical split do_less_quit(s) do_delete_other_windows(s) deletes other windows (!) do_minibuffer_exit(s) also deletes completion_popup insert_window_left() deletes some left-most windows do_list_buffers() do_dired()

Search / Replace

unihex search broken for non ASCII chars

query_replace_replace for non utf8 buffers

regex search/replace (use glibc 2.1 regex.c file)

search replace across multiple files

faster search

is->dir fixup in incremental search

query-replace options: u -> undo last change

Unicode / bidir

set_input_method() and set_buffer_file_coding_system() in config file.

autocomplete keyword, function, variable, member names

forward-ifdef, backward-ifdef, show-ifdefs

cmdline arg to force lines and columns to test shell.

toggling interactive shell mode is not automatic enough

man pager -> more bindings

accented letter input in shell mode

transcode between tty charset and shell buffer charset
