<none>

MEDIUM-TERM PROJECTS
--------------------
* Need to have a script that implements per-channel FiSH support
* There needs to be an /on switch_query for wuf/sjhoran
* What about scrolling back to some point in time?
* What about a facility to do auto-off-hold-mode ?
* wuf says that fred!user@machine.domain.com.au should not be
	*!*user@*.com.au but instead *!*user@*.domain.com.au
* There should be a fake level for "channel stuff"
* Curse would like an outbound protocol queue to avoid flooding the server
* Larne wants syntactic word extraction like $foo{3} or $foo{1,4}
* Howl wants to be able to have per-window /input and /input_char
* Howl would like "advanced scrollback" searches, like hit counts
* I think maybe i should expose a better scrollback interface?
* Should be able to change LINE value in windows (for howl)
* Howl would like to be able to replace any line of scrollback via windowctl
* Kitambi would like to be able to rewrite lines after they've been displayed.
* Should any commands be #ifdef'd out at compile time, as opposed to just
  being replaced with error-generating shims?
* /Foreach should work with local variables.  It can't right now because
  of the challenge of indicating which elements are from local variables.
* Harz would like a way to do /bind -default for just a single binding.
* /PAUSE does not save/restore context, and it should.
* You should be able to pass in arglists to /exec -line and /exec -end
* You should be able to pass in extra args to /exec -line and /exec -end
* The "anonymous function" statement -- (arglist) {block}
* /window maximize + new status expando when a zero-height window gets output

* Don't lamely malloc_strcpy() over non-malloced strings in hookctl.
* Add $iconvctl() to control iconv stuff. (See UPDATES.)
* Add $xform(iconv +<iconv id>) functionality. (See UPDATES.)
* Fix bug where /window number could lead to confused lastlogs
* Generalize base64 encoding so it doesn't hardcode the base64 string.
* Add $xform(+FISH64 ...) which does FiSH's base64 encoding.

* Rework the ruby checking in configure so it builds on freebsd-7
* Add CTCP FISH support (this is _not_ fish support!), see UPDATES
* Make an initial stab at proper support for FiSH's base64 converter.
* I took the "fish64" entry out of $xform() for now while it's broken.
* Capture stdout of ruby scripts and send it to an epic window. yay!
* This means you can do regular old 'puts' in ruby script and it'll Just Work.

* New file, wcwidth.c, utf8<->unicode conversion, unicode column counting.
* Revamp /INPUT system to be utf8 aware.  callback 2nd arg is now const.
* Specifically, save the state of the input line across /INPUTs.
* -- This is stub code. needs to be completely fleshed out.
* Reformat keys.c so I can work with it easier
* Only bytes < 127 can now participate in binds.  >= 128 are SELF_INSERT.
* I think the keybinding system can grow 'namespaces' which might be cool.
* The TRANSPOSE_CHARACTERS keybinding has passed away quietly.
* New keybinding DEBUG_INPUT_LINE to help me

* The ability to 'fake' input in dumb mode has passed away quietly.
* Completely revamp input.c to work with inputline data structure
* Change input line so users operate on "logical characters"
* Inputline data structure maps "logical characters" to bytes in input buffer.
* It's almost too overwhelming to describe specific details.
* Basically the input system accepts unicode code points, and stores in utf8.
* Things like cursor movement, column counting, side scrolling all Just Work.
* Even things like cut buffering work.
* HOWEVER -- it seems this stuff doesn't work in GNU screen. can't fix this. :/
* Internal function strext2() allows me to cut substrings out, for input buf.
* Fix input_delete_character(), it forgot to call retokenize_input()
* Fix term_inputline_putchar() so it doesn't mangle 0x9b (valid utf8 char)
* Fix $curpos(), sort of.  Does this return byte offset or column offset?
* 	It used to be the same, but now it's not!
* InputLine.buffer_pos isn't used any more.  Whack that.
* Test every keybinding, fix the ones that are broken.
* Fix handling of highlight chars
* Add "number_of_logical_chars" to input line so we can boundary check eol.
* Error if you try to /bind a high bit char -- that's illegal now.
* Test and fix composed characters (for mac os x)
* Teach the normalize_string, prepare_display, and output_with_count about utf8
* Since utf8 parsing is "consumptive", some utility funcs changed too
* Column counting/line wrapping in the display works correctly now.

* Extend $chr() to accept U+xxxx strings
* Add function $unicode() converts input into U+xxxx strings

* Translate screen output to /encoding console setting
* Non-utf8 users now appear as utf8 users to irc!
* UTF8 users now appear as non-utf8 users to non-utf8 epic users!
* Automatically recode undeclared non-utf8 scripts using /encoding scripts
* Add Emojis (unicode 6) to the column counting code (rb Kitambi)
* Set /ENCODING CONSOLE automatically to nl_langinfo(CODESET) from LC_ALL.
* If the default codeset is "US-ASCII" then it's changed to ISO-885-1.
* In translate_user_input() try to detect utf8 typers using non-utf8 encodings
* Tell user if we're recoding a script at /load time.

* Re-implement status repeat-char-fill for utf8. (rb fudd)
* Fix /xtype -l to be UTF-8 aware. (rb zlonix)
* When status updates are suppressed, make a note if an attempt is tried
* When status updates are permitted again, do an update_all_status() if defered
* Make /set lastlog do a scrollback redraw to "dispose" of extra lines
* Make /set lastlog refuse to set to a value < twice the biggest window.
* However, doing /set lastlog 0 WILL delete everything and clear every window.
* Have configure auto-detect your "local" directory (/usr/local|opt|/usr/pkg)
* Have configure use the auto-detected local directory.
* Reformat some parts of server.c
* Change the current window whenever we're processing server stuff.
