18       
192.1.8
20        Do OLC formatting for anything coming from olc.matisse
21        Improvements to popup size algorithm (from gildea)
22        Improved 'show colors' with non-colored labels
23

25        The colorclass command is added, to make colorization easy
26        Handle MIT Athena OLC zephyrs correctly
27        Updated ktools website / bug address
28        Do ntohs() when printing zephyr port in zephyr info
29        Updated man page
30       
312.1.6
32        Fixed three bugs found by Valgrind.
33        Fixed a case where doing "aim addbuddy" instead of "addbuddy aim"
34          would cause a segfault.
35        pexec will now incrimentally display data as it is output
36          by the child process.  Additionally, commands running under
37          pexec may now be killed by quitting out of the popless window.
38        Added muxevents select loop dispatcher.  File descriptors may
39          be registered with muxevents and handlers will be dispatched
40          to when data is available for non-blocking read/write/except.
41        Switched the stderr_redir stuff to use muxevents.
42        Print C-\ correctly (from gildea)
43        Dropped first brace in muxevents functions for consistency
44        Catch SIGHUP and SIGTERM and do a proper logout
45       
462.1.5
47        Added a licence
48        The 'personalbell' variable can now be set to 'on' 'off' or
49          the name of a filter to match against
50        The 'loglogins' variable now controls whether login/logout
51          messages are logged.  It is off by default.  For now this
52          affects only AIM messages, later zephyr login/logout messages
53          will also be logged if this is set to 'on'
54        Added 'show license'
55       
562.1.4
57        Normalize and downcase AIM names for logging
58        Fixed a bug where sending a null zsig could cause a crash
59        Better 'away' toggling if only one protocol is away.
60
612.1.3
62        Added perl filter elements.  Similar to having "filter <subfilter>"
63          in a filter, you may also have "perl <functionname>"
64          where <functionname> is passed an owl::Message object and
65          returns 0 or 1 depending on whether the message matches
66          that element of the filter.
67        Don't print an error about loading subs if there is no
68          .zephyr.subs
69        Do the initial zephyr_buddy_check when pseduologin set to true.
70        Updated man page
71       
722.1.2
73        removed unused filter_depth variable
74        Fixed memory bug on receiving pings
75       
762.1.1
77        Filters of filters now work.
78        Removed the "possibly not readable" part of the config parsing
79          error
80        In the sepbar, reverse video the view name when it's not set to
81          view_home (as opposed to the static 'all').
82        The '!' key (bound to 'view -r') now creates a negative version of
83          the current view and switches to it.  i.e. "show me all the
84          messages that are not these"
85        Added the 'ignorelogins' variable
86        Log when outgoing personal message fails
87        Removed file descriptor from sigpipe catcher printer just for now,
88          since the field does not exist on OSX
89        Added an ifndef for socklen_t in libfaim/ft.c
90        Added the 'aim search' command.  The popup on callback may be
91          dangerous, should switch to an admin msg for results, or add a
92          new event queue
93        First pass at AIM away messages.  It is a little different from
94          what most clients seem to do, in that an away reply is sent for
95          each message received.  Most clients only reply to the first one
96          per away-session.
97        Now have a set of 'aaway' commands and variables just like the
98          'zaway' ones (except that changing the 'aaway' variable talks to
99          the server)
100        The new 'away' command does everything for both AIM *and* zephyr.
101          There is a known funkiness here, where if you turn one away on,
102          and then use 'away' (or 'A') to toggle, you will turn on off and
103          the other on.  Just leaving it for now.  Should do better in the
104          next patch.
105        The 'A' key is bound to 'away'
106        Status bar can now read AWAY, Z-AWAY or A-AWAY.
107        Changed C-n to scroll down just a line in popless
108        If the config exists but is not readable, print an error before
109          exiting
110        Only print forced AIM logout message once.
111        Don't bind F1 to help in edit context
112        Fix bug in 'getsubs' with no tickets
113        New code for getting users from .anyfile
114        Added the 'pseudologins' variable, and code to do it
115        new attributes 'pseudo' 'logintty' and 'loginhost'
116        Don't print extra new lines in popless_file
117        New zephyr_get_field function
118       
1192.0.14
120        Fixed missing word in startup message
121        Better 'status' command
122        Use '+' for popwin corners when 'fancylines' is off
123        Allow TERMINFO to be overridden in the envrionment
124        Command line arg -D turns on debugging and deletes previous
125          debugging file
126        Do ~ expansion in 'dump' command.
127        Current directory added to 'status' command
128        Massive changes to libfaim and aim
129       
1302.0.13
131        Changed startup message for new mailing list
132        blist now prints AIM info even if .anyone is unreadable
133        Catch SIGPIPE and print an error rather than crashing.
134                [It's possible that this may have some portability
135                issues under Solaris and we may need to add some
136                configure stuff around SA_SIGINFO...]
137        Handle the case in aim_bstream_send where aim_send returns -1,
138                although there is likely an underlying problem here
139                that would lead to this case.
140        Print the username on aim login failure, not something random like
141                the password.  ;)
142        Un-word-wrap text when sending AIM messages.
143        Replace the main loop continue in the keyboard handler with an else.
144       
1452.0.12
146        Command history now doesn't allow the last entry
147           to be repeated
148        If format_msg returns "" print "<unformatted message>"
149        Better align oneline admin and loopback messages
150        Print an admin message indicating when subscriptions can
151           not be loaded on startup
152        Set aim_ignorelogin_timer to 15 by default
153        Admin message on login/logout of AIM
154        Fixed double quoting in smartzpunt
155        Added timestamp to login/logout messages
156        Fixed replies to loopback messages
157        Fixed smartnarrow on classes/instances with spaces
158        Added the 'loggingdirection' variable
159        All loopback messages log to 'loopback' now
160        Print an error message if trying an invalid color for a filter
161        Fixed bug causing > not to go to end of editwin every time

1632.0.11
164        Updated basic help
165        Display CC: in outgoing CC messages
166        More AIM logout detection
167        Don't proclaim "interfaces changed" on first build.
168        Added the 'loopback' message type
169        Added the 'loopwrite' command
170        Added a timestamp to the default style
171        Zpunt now works with weird regex characters

185           from commands and displaying them in the errors buffer.
186        Create an admin message explaning that a zephyr couldn't
187           be sent
188        Better reporting of perl errors (both into the errqueue
189                and also clearing the error after displaying it).

202        Add owl::login and owl::auth to legacy variables populated for format_msg.
203        Additions to intro.txt and advanced.txt documents.  (Still in progress.)
204        Add base methods for login_host and login_tty
205                and others that return undef.
206        New API for perl message formatting functions. 
207                Legacy variables are still supported for owl::format_msg
208                and owl::receive_msg, but these functions are now also
209                passed an owl::Message object which contains methods
210                for accessing the contents of the message.  See perlwrap.pm
211                (and docs TBD) for the available methods.
212                *** WARNING:  The exact API for owl::Message has
213                *** not yet stabilized.
214        Added "style" command for creating new styles.

217                from list to dictionary.
218        Changed AIM password prompt from "Password:" to "AIM Password:".
219        Messages are reformatted after a window resize to allow styles
220                to take into account the width of the window.
221        When perl throws an error, the message is put in the msgwin
222                if possible.
223        Added perl functions for:       
224                owl::getcurmsg() -- returns an owl::Message object for
225                                    the active message
226                                    in the current view.
227                owl::getnumcols() -- returns the column width of the window
228                owl::zephyr_getrealm() -- returns the zephyr realm
229                owl::zephyr_getsender() -- returns the zephyr sender
230        Made owl::COMMAND("foo"); be syntactic sugar for
231                owl::command("COMMAND foo");
232        Added perlwrap.pm to contain perl code to be compiled into
233                the binary.  This is transformed into perlwrap.c by
234                encapsulate.pl.
235        Renamed readconfig.c to perlconfig.c and changed variables accordingly.

281        Added the 'toggle-oneline' command
282        The 'o' key is bound to 'toggle-oneline'

326        The message object now uses a list of attributes internally, in
327          prep. for supporting new messaging protocols
328        owl_function_info now uses fmtext instead of one staticly sized

357          will be executed when new messages arive that match the
358          alert_filter
359        added the 'term' command which takes the 'raise' and 'deiconify'
360          options.  It assumes xterm for now.
361        only 'make distclean' will nuke core and ~ files now
362        fixes to owl_function_do_newmsgproc from Stephen

368        configure.in: minor changes to work with new autoconf without needing acconfig.h.
369        configure.in: find the install program.
370        configure.in: test for use_default_colors since some versions of
371          solaris don't have it, so we can at least compile something
372          vaguely working there.
373        keypress.c: ifdefs for keys not defined on at least some solarises.
374        owl.c: don't call use_default_colors if we don't have it
375        readconfig.c: added *commented out* code to try to find a
376          system-default owlconf if the user doesn't have one.  Have to
377          ponder if I want this
378        zcrypt.c: don't prototype des_ecb_encrypt if there is a prototype in
379          des.h.
380        zcrypt.c: include owl.h so we get the configure-generated config.h

399          WORK yet
400        Removed a bit of faim code that allowed commands to be executed.
401        The 'B' key is now bound to 'alist'
402        Added the 'startup' and 'unstartup' commands

436        Added search, '/' and '?' to basic help.
437        Will attempt to keep the current message as close as possible
438             to the previous current message after an expunge.
439        "set <variable>" and "unset <variable>" now work for boolean variables.

457             'tty' variable before setting the zlocation
458        There is now a 'zlist' command that acts like 'znol -l'

465        The built-in personal filter is updated to do so
466        Fixed a bug in moving the pointer after an expunge
467        Fixed up the normal scrolling code.  Now it should always
468          land on a message, but it's still not optimal.
469        Added the variable 'smartstrip' which will strip kerberos
470          instances out for the 'reply' command.
471        Added -R/usr/athena/lib to the build for Athena
472        Started updating the intro document
473        Small changes to help / about
474        The 'subscribe' and 'unsubscribe' commands (and their aliases) now
475          update .zephyr.subs by default.  If either is given the '-t'
476          (for "temporary") option the .zephyr.subs will not be updated
477        Turned off beeping for hitting the top or bottom of the list of
478          messages
479        Made daemon.webzephyr a special case for smartstrip
480        Added 'out' as a default filter for outgoing messages
481       
4821.2.3
483        Added filters "ping", "auto" and "login" by default.
484        Added "body" as a valid field to match on in a filter.
485        Temporary fix to bug where C-SPACE would cause the key handler to
486             lock up.
487        Messages now have a direciton (in, out or none).  Filters can
488             match on this direction
489        Outbound messages are no longer type 'admin' but are of the
490             appropriate message type (i.e. 'zephyr') and are direction
491             'out'.
492        Smartnarrow now works on outgoing messages
493        'info' updated to show more information for admin and outgoing
494             messages
495        Renamed pretty_sender to short_zuser and renamed long_sender to

497        Moved zsig generation to the zwrite object
498        Print the zsig used for outgoing messages
499        The tty variable now controls the zephyr location tty name
500       
5011.2.2
502        Added the 'search' command.
503        '/' is a keybinding for 'search'
504        '?' is a keybinding for 'search -r'
505        Fixed stristr, which was completely broken
506        renamed owl_fmtext_ztext_stylestrip to owl_function_ztext_styletsrip
507             and put it in functions.c
508        Attempts to stay near the current message when switching views.
509             When switching from an empty view to one we've previously
510             been in, the new current message position will attempt
511             to be close to the current position from the last
512             time we visited that view.
513        Fixed bug in readconfig.c that prevented building under perl 5.005.
514        Switched "C-x C-x" to only "startcommand quit"
515        'getsubs' prints closer to the order you sub in.
516        Modified the behavior of last so that "> >" will clear the screen.
517        The new behavior of last is:
518              Moves the pointer to the last message in the view.
519              If we are already at the last message in the view,
520              blanks the screen and moves just past the end of the view
521              so that new messages will appear starting at the top
522              of the screen.
523        Fixed a typo in the help for smartzpunt.
524        Fixed functions to handle curmsg being past the end of the view.
525
5261.2.1
527        New framework for command handling.
528        New framework for keymap handling.
529        Added commands for everything that is bound
530             to a key (do 'show commands' to get the full list).
531        Added 'multi' and '(' commands to allow multiple commands
532             to be specified on a line.             
533        Added user keybindings with bindkey command.
534        Added command aliases (eg, "alias foo bar").
535        Added undelete command that parallels the delete command.
536        Added additional options to delete command.
537        The reply command now takes arguments.
538        Added 'edit:insert-text' command.
539        Added 'show zpunts' to show active punt filters.
540        Added 'show variable <name>' and 'show variables'.
541        Added 'show command <name>' and 'show commands'.
542        Added 'show keymap <name>' and 'show keymaps'.
543        Added 'M-u' to undelete all messages in current view.
544        Fixed dotsend so that the zephyr will still send if there
545             is whitespace after the dot but not on the same line.
546             This should resolve an issue where dotsend wouldn't work
547             if you'd gone up and edited a zephyr.
548        Bug in page down fixed
549        C-t will transpose characters
550        Fix the scrolling bug where we would sometimes fail to scroll
551             the screen down, leaving the current message off
552             the bottom of the screen.
553        Refixed 'login or login' typo in help
554        Fixed M-u description
555        Removed 'first' and 'last' from basic command help
556        Added M-N to basic key help
557        Added M-D, M-u to basic key help
558        Fixed a quoting problem in configure.in
559        Changed top of help to use 'show' instead of M-x
560        Fixed a bug in the summary field for user-created aliases
561        Added "reply zaway" which sends a zaway response to the current msg.
562        Added "edit:delete-prev-word" command and bound M-BACKSPACE to it.
563        Some buffer overruns fixed
564        Variables now have a summary and a long description.
565                Only the summary is shown with help.
566                The long description is shown with "show variable foo".
567        Added a 'scrollmode' variable which determines how the screen
568             will scroll as the cursor moves.  The default behaves
569             identically to previous versions of owl.
570             The following modes are supported:
571             normal      - This is the owl default.  Scrolling happens
572                           when it needs to, and an attempt is made to
573                           keep the current message roughly near
574                           the middle of the screen.  (default)
575             top         - The current message will always be the
576                           the top message displayed.
577             neartop     - The current message will be one down
578                           from the top message displayed,
579                           where possible.
580             center      - An attempt is made to keep the current
581                           message near the center of the screen.
582             paged       - The top message displayed only changes
583                           when user moves the cursor to the top
584                           or bottom of the screen.  When it moves,
585                           the screen will be paged up or down and
586                           the cursor will be near the top or
587                           the bottom.
588             pagedcenter - The top message displayed only changes
589                           when user moves the cursor to the top
590                           or bottom of the screen.  When it moves,
591                           the screen will be paged up or down and
592                           the cursor will be near the center.
593        Added owl_sprintf which returns the formatted string, or NULL.
594                The caller must free this string.
595                This will allocate enough memory and thus
596                avoid potential some buffer overrun situations.
597        Simple implementation of 'zwrite -m' (doesn't yet log an outgoing
598                message as having been sent.)
599        The "Not logged in or subscribing to messages" error
600                now includes the name of the recipient.
601        The "disable-ctrl-d" variable may also be set to "middle"
602                which will result in ctrl-d only sending at the
603                end of the message.  This is now the default.
604                This also added a command "editmulti:done-or-delete".
605        Fixed a bug in the "reply -e" command.
606        Always clear the command buffer before executing the command.
607                (So that interactive commands can sanely do start-command.)
608        Fixed preservation of e->dotsend across owl_editwin_clear().
609        Added history for multiline edit windows (eg, for zephyr composition).
610                The M-n and M-p keys will cycle through the history ring.
611                In particular, it is now possible to edit the command line
612                of a zephyr being composed:  C-c it and restart it
613                and then M-p to get the aborted composition back.
614        Added owl::send_zwrite(command, message) to the perl glue
615                to allow for the direct sending of multi-line messages.
616                For example:  owl::send_zwrite("-c foo -i bar", "hello");
617        Changed owl_fmtext_print_plain to return an alloc'd string to
618                avoid buffer overrun risks.
619        Added owl::ztext_stylestrip("...") function to perlglue
620                 which returns the ztext with formatting stripped out.
621        Added colorztext variable which can be used to disable @color()
622                 strings arriving in messages after it is set.
623                 (Currently, changing its value won't reformat messages).
624        Outgoing zephyr logging now obeys the logpath variable.
625        The '~' character in logpath and classlogpath now gets
626                 replaced with the user's home directory.
627        Added simple implementation of smartnarrow-to-admin that
628                 creates a "type-admin" autofilter.
629                 This was done mostly so that M-C-n and M-C-p do something
630                 sane on admin messages.
631        Added opera to the allowed options to the webbrowser variable.
632        Fixed some buffer overruns in the "reply" command.
633        When repying to "all" on a message that begins with "CC:" (eg, sent
634                 with "zwrite -C", the reply line will be constructed
635                 from the sender and the usernames on the CC: line
636                 of the message being replied to.
637        There is no such thing as C-R, so left C-r as it is but added:
638                 M-r --- edit reply to all
639                 M-R --- edit reply to sender
640        Added RCS Id strings to all files.
641        'show keymaps' shows details of all keymaps after summary list.
642        Added --no-move option to delete command.
643                In particular, delete-and-always-move-down may now
644                be implemented with
645                '( delete --no-move ; next --skip-deleted )'.
646        Folded the nextmsg and prevmsg commands and functions together into
647                one command which takes arguments.
648                Added '--filter <name>' option (eg, for next_personal),
649                '--skip-deleted' option, and
650                '--last-if-none'/'--first-if-none' options.
651                Help updated accordingly. 
652                In particular, the 'personal' filter is now used
653                for 'next personal'. 
654                Added --smart-filter and --smart-filter-instance options
655                to the next and prev commands.
656        Updated examples/owlconf.erik with the above.
657        Made owl_function_fast*filt return a string and not do the
658                narrowing, to make it more general.
659        Added a smartfilter command that creates a filter
660                based on the current message and returns the name
661                of the filter.
662        Added M-C-n and M-C-p keybindings to "move to next message
663                matching current" and "move to previous message
664                matching current"
665        Added variables edit:maxfillcols and edit:maxwrapcols which
666                will limit how wide editing paragraphs may get before
667                they get wrapped.  This is a max and may be narrower
668                depending on the current size of the window.
669                If 0, the max is unlimited.  Default is 70 columns for
670                edit:maxfillcols and unlimited for edit:maxwrapcols.
671        Added smartzpunt command with key binding of "C-x k".
672                This starts a zpunt command filled in with
673                the proposed zpunt.
674        Fixed a memory reference bug in delete and undelete commands.
675        Added support for perl to call directly back into owl.
676        Changed the implementation of owl::command("...") to immediately
677                call back into owl.  This allows perl to get the return
678                value of strings returned by owl commands.
679        Added the getview command which returns the name of the current
680                view's filter. 
681        Added the getvar command which returns the value of a variable.
682        Added an example to examples/owlconf.erik which uses TAB to
683                narrow and restore the view. 
684        Added an example to examples/owlconf.erik which uses M-c to
685                color messages matching the current one green.
686        Integrated change to fix problem with popup blinking on new zephyrs.
687        C-l and resizes will now refresh an open viewwin (eg, help).
688        Updated doc/code.txt to include info about filters, commands,
689                contexts, and keybindings.
690        Exec commands cleaned up to not have buffer-size limitations
691                and to not mess up spaces.  exec also returns a string
692                of the output now.
693        Integrated changes from 1.1.3, and added docs for "zlocate -d"
694                and new show commands.
695        Show with arguments produces help on show.
696        Fix a bug in readconfig caught by efence (where we'd try to read before
697                the beginning of a string if it was empty).
698        The perl command doesn't do makemsg directly, but instead
699             returns the string and it will get printed if it
700             was run interactively.
701       
7021.1.3
703        'show subs' and 'show subscriptions' are now the same as 'getsubs'
704        zlocate now takes an optional -d argument

714        'show terminal' includes whether the terminal can change colors
715        fixed off by one bugs in paging / scrolling viewwin
716        don't downcase the sender when getting the log name for personals
717        support @owl::fields as well as @fields
718        downcase class/inst filter names in auto filters
719
7201.1.2
721        Fixed memory mishandling bug
722        Fixed bug in redfining the filter attached to the current view
723        M-n will narrow to message, instance on non-personal, class
724             MESSAGE messages
725        M-N behavies like M-n except that on class messages it narrows
726            to class and instance
727        line wrap earlier, to account for tabbing
728        fixed typo in help
729        'status' command now displays info on terminal color support

740          incoming messages
741        If colors are available 'show filters' will show a filter in the
742          color associated with it.
743        Added the zpunt and zunpunt commands
744        Lines in the subs file starting with '-' are zpunted
745        Include login/logout messages in auto user filters
746        'V' changes to the home view ('all' by default)
747

750              and spaces in a saner manner.
751        Removed all owl_get_* methods for booleans and switched
752              cases where they were used to owl_is_*
753        Changes to owlconf.erik to use some new features.
754        Increased the size of the help buffer (as it
755              was overflowing and truncating the help message).
756        Variables prefixed with a _ are not shown in help
757              or by printallvars (and prefixed Not Yet Implemented
758              variables with this).
759        Fix typo in help

814        Changed: owl_message_get_numlines will return 0 of m is NULL
815        Added login messages to messages marked by owl_function_delete_automsgs
816        Added owl_function_delete_by_id(id) which acts independent of view
817        Added "-id <id>" option to delete command
818        Fixed an arg checking bug in delete command
819        Added owl::id to perl namespace with message id
820        Fixed a memory corruption bug in readconfig.c (where right
821              after the strdup to "out", we'd strcat a \n onto the end.
822              This would be triggered whenever owl::format_msg returned
823              a string not ending in a newline
824        Added 'X' keybinding which expunges and then switches to
825              a view defined by the variable "view_home" which defaults

827        Consolidated readconfig.c somewhat to remove duplication.
828              owl_config_execute now returns a string.

840              and added regression testing framework to tester
841        Fixed codelist.pl to ignore static declarations.
842        Added dict.c which contains string->ptr dictionary routines
843              and the owl_dict type.
844              These include regression tests.
845        Overhaul/rewrite of variable handling.  Variables are now managed
846              in an owl_vardict (in g.vars) which contains a dictionary
847              of owl_variable's.  Each owl_variable has dispatch functions
848              for validating values, setting it and getting it,
849              and for setting it to and from string values.
850              The variable.c file contains the list of variables.
851              Stubs for the owl_global_<varname>_get functions and friends
852              are generated from variable.c by stubgen.pl.
853              The help.c messages for variables now calls into variable.c
854              so all information about most variables is in one place.   
855        Cleaned out code from global.c and command.c that was made obselete
856              by variable overhaul.
857        The set command now takes a -q option to not log a message.

859              print "Undefined variable" in addition
860              to running owl_function_printallvars.
861        debug is now a variable that can be turned on and off.
862        Fixed mail,inbox message parsing in examples/owlconf.erik
863        Made zaway_msg and zaway_msg_default into variables
864        Changed owl_function_makemsg and owl_function_debugmsg
865               to use varargs (ie, so they can now take a format
866               string with args).
867        Don't allow " and \ characters in URLs with the "w" command.
868        Removed lots of build warnings.

876        Added appendtosepbar variable which may contain text which will
877              be appended to the sepbar.  This allows the configfile
878              to put information about pings and logins into
879              the sepbar.  (It may be worth also providing a variable
880              which enables this by default, but for now this allows
881              for experimenting with what works well.)
882        Added doc/code.txt which gives a brief overview of the code.
883        Added tags makefile rule and added TAGS to distclean rule.
884
