Priority 3

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

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

static init_call stuff ?

add default charset 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

allow recursive main loop, and remove input callbacks

fix column computation based on display properties:

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

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

notes

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

abbreviation mode

qe_realloc: typed and clear reallocated area

Moving / Editing

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)

256 color mode

auto-fill-mode

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

rectangular regions, cut/paste

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

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

search: query replace across multiple files

search: query replace options: u -> undo last change

Unicode / bidir

set_input_method() and set_buffer_file_coding_system() in config file.

fix kana input method

charset: add JIS missing encoding functions

add JIS charset probing functions

test Hebrew keymap support.

X11 display / graphics

clip display by popup size

move -nw cmd line option to tty.c and make term_probe return better score

remember X11 window positions and restore layout ?

improve image viewer.

faster video handling (generalize invalidate region system)

integrate tinySVG renderer based on the new libraster.

implement wheel mode in CSS display.

fix configure for missing support: x11 xv png …

add configure –disable-graphics

dpy_open_font should never return NULL, must have a system font.

Outline / Org mode

outline styles

implement hide / show regions

C mode

c-indent

indent-with-tabs

stats command for slcc

add TAGS support:

recursive search of QTAGS file.

idl-mode

HTML mode

distribute libqhtml as a separate project

OPTIMIZE eb_nextc et al or always duplicate box content (big speed improvement).

polish end of line offset/cursor displacement support.

handle implicit TR

add file referencing (<?xml-stylesheet type="text/css" href="xxx"?>, <link>, etc…)

fix LI numbering with VALUE attribute (cannot use CSS). Verify counter-reset semantics.

(z-index) floats must be displayed after all other stuff.

<NOBR> is sometimes incorrect.

more font style synthesis in html2ppm.

add xml CDATA parsing

Shell

fix bof/eof shell mode

allow quoting of special keys : let do_char insert xterm/vt100

key sequence to allow typing special keys into shell process

fix terminal size inside shell window ?

cmdline arg to force lines and columns to test shell.

toggling interactive shell mode is not automatic enough

man pager -> more bindings, such as RET -> push-button (jump to map page)

accented letter input in shell mode

transcode between tty charset and shell buffer charset

track unsupported escapes in shell buffer

doctor command should create and show trace buffer, remove eb_new kludge

use colorized buffer for trace buffer to flag tty input, shell output, supported and unsupported escapes.

telnet-mode: Connect to a remote computer using telnet

Dired

use buffer specific load functions

separate buffer for each directory

adjust dired gutter width for max name length
