Filters of filters now work
  • Property mode set to 100644
File size: 41.7 KB
4        Filters of filters now work.
7        Added the 'aim search' command.  The popup on callback may be
8          dangerous, should switch to an admin msg for results, or add a
9          new event queue
10        First pass at AIM away messages.  It is a little different from
11          what most clients seem to do, in that an away reply is sent for
12          each message received.  Most clients only reply to the first one
13          per away-session.
14        Now have a set of 'aaway' commands and variables just like the
15          'zaway' ones (except that changing the 'aaway' variable talks to
16          the server)
17        The new 'away' command does everything for both AIM *and* zephyr.
18          There is a known funkiness here, where if you turn one away on,
19          and then use 'away' (or 'A') to toggle, you will turn on off and
20          the other on.  Just leaving it for now.  Should do better in the
21          next patch.
22        The 'A' key is bound to 'away'
23        Status bar can now read AWAY, Z-AWAY or A-AWAY.
24        Changed C-n to scroll down just a line in popless
25        If the config exists but is not readable, print an error before
26          exiting
29        Only print forced AIM logout message once.
30        Don't bind F1 to help in edit context
31        Fix bug in 'getsubs' with no tickets
32        New code for getting users from .anyfile
33        Added the 'pseudologins' variable, and code to do it
34        new attributes 'pseudo' 'logintty' and 'loginhost'
35        Don't print extra new lines in popless_file
36        New zephyr_get_field function
39        Fixed missing word in startup message
40        Better 'status' command
41        Use '+' for popwin corners when 'fancylines' is off
42        Allow TERMINFO to be overridden in the envrionment
43        Command line arg -D turns on debugging and deletes previous
44          debugging file
45        Do ~ expansion in 'dump' command.
46        Current directory added to 'status' command
47        Massive changes to libfaim and aim
50        Changed startup message for new mailing list
51        blist now prints AIM info even if .anyone is unreadable
52        Catch SIGPIPE and print an error rather than crashing.
53                [It's possible that this may have some portability
54                issues under Solaris and we may need to add some
55                configure stuff around SA_SIGINFO...]
56        Handle the case in aim_bstream_send where aim_send returns -1,
57                although there is likely an underlying problem here
58                that would lead to this case.
59        Print the username on aim login failure, not something random like
60                the password.  ;)
61        Un-word-wrap text when sending AIM messages.
62        Replace the main loop continue in the keyboard handler with an else.
65        Command history now doesn't allow the last entry
66           to be repeated
67        If format_msg returns "" print "<unformatted message>"
68        Better align oneline admin and loopback messages
69        Print an admin message indicating when subscriptions can
70           not be loaded on startup
71        Set aim_ignorelogin_timer to 15 by default
72        Admin message on login/logout of AIM
73        Fixed double quoting in smartzpunt
74        Added timestamp to login/logout messages
75        Fixed replies to loopback messages
76        Fixed smartnarrow on classes/instances with spaces
77        Added the 'loggingdirection' variable
78        All loopback messages log to 'loopback' now
79        Print an error message if trying an invalid color for a filter
80        Fixed bug causing > not to go to end of editwin every time
83        Updated basic help
84        Display CC: in outgoing CC messages
85        More AIM logout detection
86        Don't proclaim "interfaces changed" on first build.
87        Added the 'loopback' message type
88        Added the 'loopwrite' command
89        Added a timestamp to the default style
90        Zpunt now works with weird regex characters
91        Smart filters now work with weird regex characters
94        Allow 'hostname' in filters.
95        Fixed bug in reporting when no one is subbed to a class
96        Added an extral newline in logging incoming zephyrs
97        An admin message is displayed when you are logged out of AIM
98        Print an error message and admin message if an AIM send fails
101        Added the 'fancylines' variable.
102        Added the 'show startup' command.
103        Added feature for capturing stderr messages
104           from commands and displaying them in the errors buffer.
105        Create an admin message explaning that a zephyr couldn't
106           be sent
107        Better reporting of perl errors (both into the errqueue
108                and also clearing the error after displaying it).
109        Allow default_style to be specified in config.
110        Added errqueue
111        Added command "show errors"
112        Fixed bug removing newlines in backup files

120                returned by perl style formatting functions.
121        Add owl::login and owl::auth to legacy variables populated for format_msg.
122        Additions to intro.txt and advanced.txt documents.  (Still in progress.)
123        Add base methods for login_host and login_tty
124                and others that return undef.
125        New API for perl message formatting functions. 
126                Legacy variables are still supported for owl::format_msg
127                and owl::receive_msg, but these functions are now also
128                passed an owl::Message object which contains methods
129                for accessing the contents of the message.  See
130                (and docs TBD) for the available methods.
131                *** WARNING:  The exact API for owl::Message has
132                *** not yet stabilized.
133        Added "style" command for creating new styles.
134                Usage:  style <name> perl <function_name>
135        Added support for "show styles".  Changed global style table
136                from list to dictionary.
137        Changed AIM password prompt from "Password:" to "AIM Password:".
138        Messages are reformatted after a window resize to allow styles
139                to take into account the width of the window.
140        When perl throws an error, the message is put in the msgwin
141                if possible.
142        Added perl functions for:       
143                owl::getcurmsg() -- returns an owl::Message object for
144                                    the active message
145                                    in the current view.
146                owl::getnumcols() -- returns the column width of the window
147                owl::zephyr_getrealm() -- returns the zephyr realm
148                owl::zephyr_getsender() -- returns the zephyr sender
149        Made owl::COMMAND("foo"); be syntactic sugar for
150                owl::command("COMMAND foo");
151        Added to contain perl code to be compiled into
152                the binary.  This is transformed into perlwrap.c by
154        Renamed readconfig.c to perlconfig.c and changed variables accordingly.

276          will be executed when new messages arive that match the
277          alert_filter
278        added the 'term' command which takes the 'raise' and 'deiconify'
279          options.  It assumes xterm for now.
280        only 'make distclean' will nuke core and ~ files now
281        fixes to owl_function_do_newmsgproc from Stephen

288 find the install program.

371        Cast to an int for isspace, to make gcc -Wall quiet
372        Added 'zlist' and 'l' to basic help.

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

384        The built-in personal filter is updated to do so
385        Fixed a bug in moving the pointer after an expunge
386        Fixed up the normal scrolling code.  Now it should always
387          land on a message, but it's still not optimal.

392        Small changes to help / about
393        The 'subscribe' and 'unsubscribe' commands (and their aliases) now
394          update .zephyr.subs by default.  If either is given the '-t'
395          (for "temporary") option the .zephyr.subs will not be updated
396        Turned off beeping for hitting the top or bottom of the list of
397          messages
398        Made daemon.webzephyr a special case for smartstrip
399        Added 'out' as a default filter for outgoing messages
402        Added filters "ping", "auto" and "login" by default.
403        Added "body" as a valid field to match on in a filter.
404        Temporary fix to bug where C-SPACE would cause the key handler to
405             lock up.
406        Messages now have a direciton (in, out or none).  Filters can
407             match on this direction
408        Outbound messages are no longer type 'admin' but are of the
409             appropriate message type (i.e. 'zephyr') and are direction
410             'out'.
411        Smartnarrow now works on outgoing messages
412        'info' updated to show more information for admin and outgoing
413             messages
414        Renamed pretty_sender to short_zuser and renamed long_sender to
415             long_zuser

423        '?' is a keybinding for 'search -r'
424        Fixed stristr, which was completely broken
425        renamed owl_fmtext_ztext_stylestrip to owl_function_ztext_styletsrip
426             and put it in functions.c
427        Attempts to stay near the current message when switching views.
428             When switching from an empty view to one we've previously
429             been in, the new current message position will attempt
430             to be close to the current position from the last
431             time we visited that view.
432        Fixed bug in readconfig.c that prevented building under perl 5.005.
433        Switched "C-x C-x" to only "startcommand quit"
434        'getsubs' prints closer to the order you sub in.
435        Modified the behavior of last so that "> >" will clear the screen.
436        The new behavior of last is:
437              Moves the pointer to the last message in the view.
438              If we are already at the last message in the view,
439              blanks the screen and moves just past the end of the view
440              so that new messages will appear starting at the top
441              of the screen.
442        Fixed a typo in the help for smartzpunt.
443        Fixed functions to handle curmsg being past the end of the view.
446        New framework for command handling.
447        New framework for keymap handling.
448        Added commands for everything that is bound
449             to a key (do 'show commands' to get the full list).
450        Added 'multi' and '(' commands to allow multiple commands
451             to be specified on a line.             
452        Added user keybindings with bindkey command.
453        Added command aliases (eg, "alias foo bar").
454        Added undelete command that parallels the delete command.
455        Added additional options to delete command.
456        The reply command now takes arguments.
457        Added 'edit:insert-text' command.
458        Added 'show zpunts' to show active punt filters.
459        Added 'show variable <name>' and 'show variables'.
460        Added 'show command <name>' and 'show commands'.
461        Added 'show keymap <name>' and 'show keymaps'.
462        Added 'M-u' to undelete all messages in current view.
463        Fixed dotsend so that the zephyr will still send if there
464             is whitespace after the dot but not on the same line.
465             This should resolve an issue where dotsend wouldn't work
466             if you'd gone up and edited a zephyr.
467        Bug in page down fixed
468        C-t will transpose characters
469        Fix the scrolling bug where we would sometimes fail to scroll
470             the screen down, leaving the current message off
471             the bottom of the screen.
472        Refixed 'login or login' typo in help
473        Fixed M-u description
474        Removed 'first' and 'last' from basic command help
475        Added M-N to basic key help
476        Added M-D, M-u to basic key help
477        Fixed a quoting problem in
478        Changed top of help to use 'show' instead of M-x
479        Fixed a bug in the summary field for user-created aliases
480        Added "reply zaway" which sends a zaway response to the current msg.
481        Added "edit:delete-prev-word" command and bound M-BACKSPACE to it.
482        Some buffer overruns fixed
483        Variables now have a summary and a long description.
484                Only the summary is shown with help.
485                The long description is shown with "show variable foo".
486        Added a 'scrollmode' variable which determines how the screen
487             will scroll as the cursor moves.  The default behaves
488             identically to previous versions of owl.
489             The following modes are supported:
490             normal      - This is the owl default.  Scrolling happens
491                           when it needs to, and an attempt is made to
492                           keep the current message roughly near
493                           the middle of the screen.  (default)
494             top         - The current message will always be the
495                           the top message displayed.
496             neartop     - The current message will be one down
497                           from the top message displayed,
498                           where possible.
499             center      - An attempt is made to keep the current
500                           message near the center of the screen.
501             paged       - The top message displayed only changes
502                           when user moves the cursor to the top
503                           or bottom of the screen.  When it moves,
504                           the screen will be paged up or down and
505                           the cursor will be near the top or
506                           the bottom.
507             pagedcenter - The top message displayed only changes
508                           when user moves the cursor to the top
509                           or bottom of the screen.  When it moves,
510                           the screen will be paged up or down and
511                           the cursor will be near the center.
512        Added owl_sprintf which returns the formatted string, or NULL.
513                The caller must free this string.
514                This will allocate enough memory and thus
515                avoid potential some buffer overrun situations.
516        Simple implementation of 'zwrite -m' (doesn't yet log an outgoing
517                message as having been sent.)
518        The "Not logged in or subscribing to messages" error
519                now includes the name of the recipient.
520        The "disable-ctrl-d" variable may also be set to "middle"
521                which will result in ctrl-d only sending at the
522                end of the message.  This is now the default.
523                This also added a command "editmulti:done-or-delete".
524        Fixed a bug in the "reply -e" command.
525        Always clear the command buffer before executing the command.
526                (So that interactive commands can sanely do start-command.)
527        Fixed preservation of e->dotsend across owl_editwin_clear().
528        Added history for multiline edit windows (eg, for zephyr composition).
529                The M-n and M-p keys will cycle through the history ring.
530                In particular, it is now possible to edit the command line
531                of a zephyr being composed:  C-c it and restart it
532                and then M-p to get the aborted composition back.
533        Added owl::send_zwrite(command, message) to the perl glue
534                to allow for the direct sending of multi-line messages.
535                For example:  owl::send_zwrite("-c foo -i bar", "hello");
536        Changed owl_fmtext_print_plain to return an alloc'd string to
537                avoid buffer overrun risks.
538        Added owl::ztext_stylestrip("...") function to perlglue
539                 which returns the ztext with formatting stripped out.
540        Added colorztext variable which can be used to disable @color()
541                 strings arriving in messages after it is set.
542                 (Currently, changing its value won't reformat messages).
543        Outgoing zephyr logging now obeys the logpath variable.
544        The '~' character in logpath and classlogpath now gets
545                 replaced with the user's home directory.
546        Added simple implementation of smartnarrow-to-admin that
547                 creates a "type-admin" autofilter.
548                 This was done mostly so that M-C-n and M-C-p do something
549                 sane on admin messages.
550        Added opera to the allowed options to the webbrowser variable.
551        Fixed some buffer overruns in the "reply" command.
552        When repying to "all" on a message that begins with "CC:" (eg, sent
553                 with "zwrite -C", the reply line will be constructed
554                 from the sender and the usernames on the CC: line
555                 of the message being replied to.
556        There is no such thing as C-R, so left C-r as it is but added:
557                 M-r --- edit reply to all
558                 M-R --- edit reply to sender
559        Added RCS Id strings to all files.
560        'show keymaps' shows details of all keymaps after summary list.
561        Added --no-move option to delete command.
562                In particular, delete-and-always-move-down may now
563                be implemented with
564                '( delete --no-move ; next --skip-deleted )'.
565        Folded the nextmsg and prevmsg commands and functions together into
566                one command which takes arguments.
567                Added '--filter <name>' option (eg, for next_personal),
568                '--skip-deleted' option, and
569                '--last-if-none'/'--first-if-none' options.
570                Help updated accordingly. 
571                In particular, the 'personal' filter is now used
572                for 'next personal'. 
573                Added --smart-filter and --smart-filter-instance options
574                to the next and prev commands.
575        Updated examples/owlconf.erik with the above.
576        Made owl_function_fast*filt return a string and not do the
577                narrowing, to make it more general.
578        Added a smartfilter command that creates a filter
579                based on the current message and returns the name
580                of the filter.
581        Added M-C-n and M-C-p keybindings to "move to next message
582                matching current" and "move to previous message
583                matching current"
584        Added variables edit:maxfillcols and edit:maxwrapcols which
585                will limit how wide editing paragraphs may get before
586                they get wrapped.  This is a max and may be narrower
587                depending on the current size of the window.
588                If 0, the max is unlimited.  Default is 70 columns for
589                edit:maxfillcols and unlimited for edit:maxwrapcols.
590        Added smartzpunt command with key binding of "C-x k".
591                This starts a zpunt command filled in with
592                the proposed zpunt.
593        Fixed a memory reference bug in delete and undelete commands.
594        Added support for perl to call directly back into owl.
595        Changed the implementation of owl::command("...") to immediately
596                call back into owl.  This allows perl to get the return
597                value of strings returned by owl commands.
598        Added the getview command which returns the name of the current
599                view's filter. 
600        Added the getvar command which returns the value of a variable.
601        Added an example to examples/owlconf.erik which uses TAB to
602                narrow and restore the view. 
603        Added an example to examples/owlconf.erik which uses M-c to
604                color messages matching the current one green.
605        Integrated change to fix problem with popup blinking on new zephyrs.
606        C-l and resizes will now refresh an open viewwin (eg, help).
607        Updated doc/code.txt to include info about filters, commands,
608                contexts, and keybindings.
609        Exec commands cleaned up to not have buffer-size limitations
610                and to not mess up spaces.  exec also returns a string
611                of the output now.
612        Integrated changes from 1.1.3, and added docs for "zlocate -d"
613                and new show commands.
614        Show with arguments produces help on show.
615        Fix a bug in readconfig caught by efence (where we'd try to read before
616                the beginning of a string if it was empty).
617        The perl command doesn't do makemsg directly, but instead
618             returns the string and it will get printed if it
619             was run interactively.
622        'show subs' and 'show subscriptions' are now the same as 'getsubs'
623        zlocate now takes an optional -d argument
624        'show terminal' / 'show term'
625        '>' / last doesn't set the last message at the top of the screen now

630        can now do 'show status'
631        can now do 'show version'
632        'status' / 'show status' includes the owl version number now
633        'show terminal' includes whether the terminal can change colors
634        fixed off by one bugs in paging / scrolling viewwin
635        don't downcase the sender when getting the log name for personals
636        support @owl::fields as well as @fields
637        downcase class/inst filter names in auto filters
640        Fixed memory mishandling bug
641        Fixed bug in redfining the filter attached to the current view
642        M-n will narrow to message, instance on non-personal, class
643             MESSAGE messages
644        M-N behavies like M-n except that on class messages it narrows
645            to class and instance
646        line wrap earlier, to account for tabbing
647        fixed typo in help
648        'status' command now displays info on terminal color support
649        zephyr @ formatting is now case independant
650        added support for color terminals
651        zephyr @color(foo) now works
652        'D' for deleted messages is now not bold, unless it's the current
653          message
654        F1 displays the help screen
655        added filter colors
656        added the 'colorview' command
657        added the 'show colors' command
658        users who don't have a .zephyr.subs get a simpler format for
659          incoming messages
660        If colors are available 'show filters' will show a filter in the
661          color associated with it.
662        Added the zpunt and zunpunt commands
663        Lines in the subs file starting with '-' are zpunted
664        Include login/logout messages in auto user filters
665        'V' changes to the home view ('all' by default)
668        Fixed perl, aperl, and pperl commands to deal with quoting
669              and spaces in a saner manner.
670        Removed all owl_get_* methods for booleans and switched
671              cases where they were used to owl_is_*
672        Changes to owlconf.erik to use some new features.
673        Increased the size of the help buffer (as it
674              was overflowing and truncating the help message).
675        Variables prefixed with a _ are not shown in help
676              or by printallvars (and prefixed Not Yet Implemented
677              variables with this).
678        Fix typo in help
679        include stdio.h in functions.c
680        remove stale "q to quit" from bottom of info message

702        C-r allows you to edit the reply line
703        don't use unecessary options in reply line
704        display 'info' errors in msgwin, not popup
705        impelemnted aexec, pexec commands

722        in the configfile owl::receive_msg is run whenever a message is
723          received

727          don't seem to
728        fixed bug in displaying last line in popwin if no final '\n'
729        'T' uses the 'trash' filter now
730        zaway_msg, zaway_msg_default and zaway are all user variables now.
731        zsig variable overrides zsigproc
732        If there's no appendtosepbar don't interfear with the sepbar
733        Changed: owl_message_get_numlines will return 0 of m is NULL

735        Added owl_function_delete_by_id(id) which acts independent of view
736        Added "-id <id>" option to delete command
737        Fixed an arg checking bug in delete command
738        Added owl::id to perl namespace with message id
739        Fixed a memory corruption bug in readconfig.c (where right
740              after the strdup to "out", we'd strcat a \n onto the end.
741              This would be triggered whenever owl::format_msg returned
742              a string not ending in a newline
743        Added 'X' keybinding which expunges and then switches to
744              a view defined by the variable "view_home" which defaults
745              to "all"
746        Consolidated readconfig.c somewhat to remove duplication.
747              owl_config_execute now returns a string.
748        Added an example config file that does vt-style formatting.
749              (examples/owlconf.vtformat)
750        Added the 'perl', 'aperl', and 'pperl' commands which will
751              evaluate perl expressions.
752        Fixed bug where pclose zsigproc would cause zombies
753        Can set zsigproc or zsig to "" to disable
754        Added support for multiple browsers (galeon and none were added).
755              Configure with the "webbrowser" variable.
756        Changing typewinsize height triggers resize event.
757        Added zsig variable which will be used if no zsigproc and non-empty.
758        Added "make test" rule to Makefile which will run regression tests,
759              and added regression testing framework to tester
760        Fixed to ignore static declarations.
761        Added dict.c which contains string->ptr dictionary routines
762              and the owl_dict type.
763              These include regression tests.
764        Overhaul/rewrite of variable handling.  Variables are now managed
765              in an owl_vardict (in g.vars) which contains a dictionary
766              of owl_variable's.  Each owl_variable has dispatch functions
767              for validating values, setting it and getting it,
768              and for setting it to and from string values.
769              The variable.c file contains the list of variables.
770              Stubs for the owl_global_<varname>_get functions and friends
771              are generated from variable.c by
772              The help.c messages for variables now calls into variable.c
773              so all information about most variables is in one place.   
774        Cleaned out code from global.c and command.c that was made obselete
775              by variable overhaul.
776        The set command now takes a -q option to not log a message.
777        Fixed a bug where set and print with no arguments would
778              print "Undefined variable" in addition
779              to running owl_function_printallvars.
780        debug is now a variable that can be turned on and off.
781        Fixed mail,inbox message parsing in examples/owlconf.erik
782        Made zaway_msg and zaway_msg_default into variables
783        Changed owl_function_makemsg and owl_function_debugmsg
784               to use varargs (ie, so they can now take a format
785               string with args).
786        Don't allow " and \ characters in URLs with the "w" command.
787        Removed lots of build warnings.
788        Popwins are wider by default so help messages fit better.
789        Added an atokenize_free function.
790        Fixes to work with an older version of libzephyr.
791        Added dependencies on header files to
792        Added pageup and pagedown key bindings to message list
793        Added pageup and pagedown to viewwin
794        Added configfile section to doc/intro.txt (from example config file)
795        Added appendtosepbar variable which may contain text which will
796              be appended to the sepbar.  This allows the configfile
797              to put information about pings and logins into
798              the sepbar.  (It may be worth also providing a variable
799              which enables this by default, but for now this allows
800              for experimenting with what works well.)
801        Added doc/code.txt which gives a brief overview of the code.
802        Added tags makefile rule and added TAGS to distclean rule.
805        fix frees in loadsubs and loadloginsubs
806        don't return in owl_free
809        'print' and 'set' with no arguments prints all variables
810        Added the 'unsubscribe' and 'unsub' command
811        Renamed the 'unsub' command to 'unsuball'
812        Added the 'getsubs' command which is like zctl ret
813        Fixed bug in logging messages sent to more than one recipient
814        Support '-C', '-O', and '-n' options to zwrite
815        Fixed bug in owl_editwin_delete_char when there are no later chars
816          after the cursor
817        Make "more" and "truncated" work in the status bar
818        enable printing of zsigproc and loginsubs variables
819        only allow message scrolling if the message is actually off the
820          screen
821        'T' will mark all automated message for deletion
