Example: + #alias (=#print is illegal, while + #alias "("=#print is ok. + #alias {}=#print is ok, + #alias \\{=#print is ok too as it matches \{ and _not_ { + * Removed a redundant alias unescaping.

Helps turning things like + * HP:Fine>You hit the wolf's head hard. + into + * HP:Fine> + You hit the wolf's head hard. + Anyway, such data has _always_ been considered separate + from the prompt if it set #isprompt, i.e. #action patterns like + "^You hit the wolf" already worked in the above case. + +Changes from 1.1.4 to 1.1.5 (Massimiliano Ghilardi) 30 Aug 1998 + * Massive code cleanup. + * Finished removing size limits on strings, text lines and variables. + * Renamed `#settimer' as `#setvar timer' and `#lines' as `#setvar lines' + Added `#setvar mem' to set/edit/remove length limit on text/strings. + * Powwow now stops command execution after any error. + * #key now works also with editing keys. + * Added #keyedit command. "#keyedit &prev-line" runs + the editing function `&prev-line' and so on. + * Added "&insert-string <string>" editing function. + * Added #mark ^pattern, which matches only at line start. + * Decreased CPU usage when/after a lot of variables, aliases or marks + are created. + * Added `*' and `*=' math operator for strings. + * Fixed math operators ^^=, ||= and &&= to always return 0 or 1. + * Fixed SEGFAULT when creating more than 100 variables. + (bug introduced in 1.1.0) + * Fixed SEGFAULT when realloc()ing very big strings. + * Fixed memory leaks when running out of memory. + * Fixed escaping/printing of nasty strings like + backslash + control char. + * Fixed some redrawing glitches on very long input lines. + Input lines bigger than the whole window are still not drawn + correctly. Same problem on prompts longer than a line. + * Fixed #prompts to fully work also on prompts received inside + a set of newline-terminated lines. + * Documented #prompt, #capture and #movie to work only for + the main MUD connection + +Changes from 1.1.3 to 1.1.4 (Massimiliano Ghilardi) 23 Jul 1998 + * Renamed `movie_play' to `movie'. Will do the replay if invoked as + `movie_play' and will convert to ASCII if invoked as `movie2ascii' + * Fixed a 1.1.1 bug that could cause a lot of missed binds. + * Finished adding ANSI prototypes. Renamed some files and remixed + some code in the process. + * Removed -DUSE_TERMIO. If you used it, no problem. + If you didn't use it, you must now add -DUSE_SGTTY. + * Fixed a few compiling problems on OSF1 and other systems + with really annoying compilers. + * Fixed missing sig_oneshot on systems without SA_ONESHOT + * Fixed input of chars with high bit set (again). + +Changes from 1.1.2 to 1.1.3 (Massimiliano Ghilardi) 21 Jul 1998 + * Variable names are now expressions too. This means that + @("foo"+"bar") is the variable @foobar. + * Added `just in time' substitution: ${varname} @{varname} and #{expr} + Not yet implemented for regexp patterns, sorry. + This introduces a subtle incompatibility with older versions, + as now also text coming from $n substitution gets unescaped. + Sorry again. (see powwow.doc for details). + * #action and #prompt did not work when using an expression + as pattern. Now fixed. + * Fixed small bug in anonymous actions. Someone still using them? + * powwow_help renamed powwow.help + * Fixed a bug in #alias: $1..$9 all contained the first word ($1) + * Fixed math operators . : .? :? .< .> <. >. :< :> <: >: which + segfaulted on empty strings (bug introduced in 1.1.0) + * Made SIGINT signal handler non-permanent to allow interrupting + system calls like connect(). Partially reverses the change in 0.9.3 + * Undone a change Gustav made in 0.9.3: now #connect with no args + always lists the open connections. To open a new connection you must + give at least one argument, for example #connect main. + * Changed edit function &redraw-line not to clear prompt. + Use &redraw-line-noprompt to get the old behaviour. + * Added #movie command to record all output from the MUD + and local commands to a file, adding timestamps to allow replay + at correct speed. Also added `movie_play' standalone program + to actually do the replay. + +Changes from 1.1.1 to 1.1.2 (Massimiliano Ghilardi) 16 Jun 1998 + * The wildcard `$' now correctly matches single words only + both in #actions and in #marks. + It was (again!) matching also multiple words like `&' + * Fixed up attr and noattr math operators, which broke in 1.1.0 + * Added workaround for buggy terminals which create empty lines with + coloured background when using #hilite <whatever> on <colour>. + Must compile with -DBUG_ANSI to enable it. + +Changes from 1.1.0 to 1.1.1 (Massimiliano Ghilardi) 11 Jun 1998 + * Added some changes from 1.0.1 that didn't go in 1.1.0. + The 1.0.x and the 1.1.x trees are indipendent... + * Wrote a memmem() replacement for systems that don't have it. + * Decreased CPU usage when receiving lots of text from the terminal + (for example using cut-n-paste) + * Continued adding ANSI prototypes. + +Changes from 1.0.0 to 1.1.0 (Massimiliano Ghilardi) 20 May 1998 + * Splitted 1.0.x and 1.1.x source trees. + * Started adding ANSI function prototypes. + Old K&R compilers still work. + * Removed all size limits in all strings, text lines and variables. + Also allowed '\0' (ASCII zero) in strings. + It was a _huge_ task! Probably messed up all and everything. + * Side effect of the above: lines of arbitrary length received from + the MUD should now work perfectly (at least as long as you have + enough memory) + +Changes from 1.0.0 to 1.0.1 (Massimiliano Ghilardi) 18 May 1998 + * Changed name of some files (Changelog, Hacking, Compile.how, + Config.demo) + * Fixed #capture and #record to save text from main connection only. + * Fixed a buffer overrun in $last_line when receiving lines longer + than 1024 chars. Hopefully lines up to 4095 chars will now work. + * Fixed message "Creating %s" when creating a new definition file. + * Added `catrw' standalone mini-program for splitting powwow output + in multiple windows (quick tutorial in powwow.doc, section #write) + * Added #rebindall and #rebindALL + +Changes from 0.9.9 to 1.0.0 (Massimiliano Ghilardi) 13 May 1998 + * Disabled NAGLE for tcp connections (set TCP_NODELAY option) + which should hopefully increase performance during lossy conditions + (idea and code contributed by Finne Arne Gangstad) + * Cleaned up error handling. Powwow tries really hard to report + any system call error, quitting only when there is really no hope. + Anyway, if you get a '#system call error' message, you should + seriously consider quitting as soon as possible since either + the connection is messed up or your system is running + out of resources. + * Removed extra newline after prompt bug when in #option -compact mode, + introduced in 0.9.7 + * Fixed $last_line to contain last non-empty line from the MUD. + * Updated config.demo with definitions for time-inside-prompt + and other things. + +Changes from 0.9.8 to 0.9.9 (Massimiliano Ghilardi) 12 May 1998 + * Changed rx.h to regex.h in includes + * Fixed behaviour on prompts and lines received in multiple packets: + 0.9.7 and 0.9.8 sometimes print garbage. + * Added some flush()es in the code to cope with the new + terminal I/O buffering. + +Changes from 0.9.7 to 0.9.8 (Massimiliano Ghilardi) 11 May 1998 + * Fixed compile problems on AIX (got out of sync). + * Fixed a stupid bug that caused all actions to be regexp + (introduced in 0.9.7) + * Introduced a more efficient terminal I/O buffering. + +Changes from 0.9.6 to 0.9.7 (Massimiliano Ghilardi) 11 May 1998 + * Increased stability when receiving extremely long lines (>1024 bytes) + The fix is only partial, powwow can still crash on lines slightly + shorter than 4096 bytes when a lot of #marks are used. + * Cleaned up the names of various #defines + In particular, USETERMIO is now USE_TERMIO and + TELNETBUG is now BUG_TELNET + * Added #option autoprint, to automatically print lines matched + by #actions. + * Added #spawn command. + * Added #prompt command. Just like #action, but matches both on + prompts and on normal text. + * #actions now work differently on prompts: + prompts are not matched immediately against #actions, + but only after a \n arrives from the MUD, just in case they are + actually normal lines received in multiple packets and not prompts. + + Thanks to the this change, powwow behaves better on lines received + in two (or more) packets. + See the file powwow.doc, section `#prompt' for the gory details. + +Changes from 0.9.5 to 0.9.6 + (Gustav Hållberg, Massimiliano Ghilardi) 16 Oct 1997 + * Fixed a nasty security hole in MPI messages + * Fixed handling of \; at the end of a command + * Fixed some other problems: + short messages from MUD could interfere with remote editing, + #bind escape sequences containing \0 were incorrectly printed/saved + +Changes from 0.9.4 to 0.9.5 + (Gustav Hållberg, Massimiliano Ghilardi) 18 Sep 1997 + * Continued code cleanup + * Allowed aliases starting with `#' + * Removed #speedwalk, #info, #echo, #keyecho, #compact and #debug + and turned them into #options: `#option echo' and so on. + For compatibility, `#echo' is aliased to `#option echo' and so on. + * Fixed a dangerous bug making cursor jump to start of typed text + when receiving a line that wraps. The bug appeared in 0.9.4, + so blame Gustav ;) + * Fixed an old bug making powwow sometimes miss a bind + * Made the command from a bound key appear with `#hilite' setting + * Made a DEFAULT_HELP_DIR define in powwow.c + * Changed to from ' ' to ` ' in some messages + +Changes from 0.9.3 to 0.9.4 (Massimiliano Ghilardi) 04 Sep 1997 + * Included all the huge changes made by Gustav Hållberg: + I really have no time to double-check them all. + If something works in 0.9.2 but is broken in 0.9.4, + you know who to bother :) + * Small esthetic changes in the source, no effects on executable + * Changed identifier for regexp #actions from ']' to '%' + +Changes from 0.9.2 to 0.9.3 (Gustav Hållberg) 11 Aug 1997 + * Fixed so packets ending with \r*\n\r* set promptstr to "" + * Made all signal handlers permanent (sig_permanent) + * Debugged and reinstalled #option (it was commented out for some + obscure reason (Massimiliano: I never finished it...)), + allowing storage of command history and word + completions in the savefile. Added the 'exit' option to allow + powwow to autoexit when the last connection closes + * #echo, #info, #wrap and #debug now get saved in the savefile + * Made repetitive use of &complete-word and &complete-line cycle + through possible completions + * Made a memory-safe strdup (called str_dup) + * When starting a child viewer/editor, that process' TITLE + environment variable is set to something appropriate (?) + * Regular expressions (Extended POSIX regexp) + available for actions; uses GNU rx. + * Actions with label "" forbidden + * Added the #delim command to change word delimeter mode + * Whenever main_conn changes permanently, linemode is set to 0 and + promptstr to "" + * Fixed a crashy bug in the >: operator + * Fixed the notorious extra-space-on-insert bug (both 'ic' and 'im' + shall NOT be sent if you want to insert something) and a VT100 + mode bug while I was feeling creative + * Made the local editing protocol respect prompts (i.e. they get + rewritten after protocol messages are shown). After texts are sent + back to the mud, the output buffer is flushed (no more pressing + ENTER after you've stopped editing!) + * Fixed a few bugs in #mark; pattern "&" doesn't crash anymore. + Patterns with consecutive wildcards never worked, so I forbade them. + It could be implemented, but I hardly think it's worth it + * Added the ANSIBUG compiler directive to fix the bug in some terms + that show new lines in the current output attrib (screws #mark e.g.) + * Made '#connect' without parameters try to open a connection + titled 'main' to 'hostname' (if specified) if no conns are open. + The initstr from #init will be used in this case + * Added &transpose-words, &upcase-word and &downcase-word (defaults + to M-t, M-u and M-l). Repetition of the latter two changes case + of the whole line + * Changed default key names to be more emacs-like (C-b, Ret etc) + * Made #host get written to the savefile iff *hostname != 0, and + if powwow is started as 'powwow filename', without any #host in + the file, #init is ran immediately + * Fixed a bug in cmd_print() that didn't cope with $0 not being set + * Allowed \0 to be part of a bound key's escape sequence. New format + for #bind allows octal \012 be part of the string representation + of the esc seq (chars with high bit set get saved in octal now) + * Made permanent variables $last_line and $prompt + * Made "#var" without arguments list all defined named variables + +Changes from 0.9.1 to 0.9.2 (Massimiliano Ghilardi) 04 Jun 1997 + * Added #keyecho command toggle echo of bound keys. + Previously, this was controlled by the generic #echo command. + * CTRL-C can now safely interrupt blocking commands like + #connect and #bind. + * POWWOWDIR is now used correctly in all cases: + not only when starting powwow with a filename but also when using + #load, #save or #file + * Changed #file syntax. Now you need = before the save-file. + Putting = alone undefines the save-file and disables autosave + when you quit. + * Cleaned up naming conventions: 'session' means editing session + while 'connection' means remote host connection. + * Fixed handling of 8 bit chars typed from keyboard + * Fixed '#reset bind' which was not reloading cursor binds + * Fixed remote host name spelling in files generated by #save. + * Fixed a bug that caused powwow to crash when failing to + connect to a mud. + +Changes from 0.9.0 to 0.9.1 (Massimiliano Ghilardi) 31 Apr 1997 + * New connections opened with #connect are set as main connection. + You will have to switch back manually if you need it. + * Cleaned up multiple connection support. Better error handling. + * Cleaned up TELNETBUG support. I did not use it recently, + and was out of sync. + * Enhanced #bind syntax: now you can specify control codes + sent by your keyboard directly from the command line. + As a side effect, #exe <file now works also on files created + with #save + * Added #rebind command. Changes the control codes associated + to a key binding without changing its name or its effect. + * Added #quit command. + +Changes from 0.8.6 to 0.9.0 (Massimiliano Ghilardi) 29 Apr 1997 + * Added FreeBSD support in make_it (thanks to Jaako Knuutila) + * Cleaned up terminal interface. + * #save and #load now accept a filename as argument + * Handle SIGQUIT as SIGINT: use to stop long or infinite loops + * Now can switch main connection on the fly with ##<connection-name> + * Allow powwow #commands also on subsidiary connections + +Changes from 0.8.5 to 0.8.6 (Paolo Gatti, Massimiliano Ghilardi) 28 Apr 1997 + * Finally and definitively changed the name to powwow. + Previously, sometimes the program was referred to as pow-wow + and sometimes as powwow, generating confusion. + * Partial port of powwow to AmigaDOS. Incomplete, will NOT compile. + Paolo abandoned the project, so maybe it will just never compile. + * Fixed a bug causing extra new-lines on screen when powwow received + strange data sequences like ASCII codes 10 13 + (on DOS, new-line is 13 10, while on UN*X is 10 only) + * Fixed a bug in #mark not matching correctly the wildcard $ + * Powwow crashed #loading files containing empty lines. Fixed + +Changes from 0.8.4 to 0.8.5 (Massimiliano Ghilardi) + * Fixed a bug introduced by updating files from cancan 2.6.0b sources + (happened in version 0.8.3): powwow was sendind TWO new-line chars + instead of one immediately after every password. + +Changes from 0.8.3 to 0.8.4 (Massimiliano Ghilardi) + * Fixed (I hope definitively) an ancient bug: + some lines were sometimes printed twice or not printed at all. + It is still the bug that appeared in version 0.4... + The bug was almost fixed in version 0.8b but reintroduced in 0.8.3 + +Changes from 0.8b to 0.8.3 (Massimiliano Ghilardi) + * Slightly changed version numbering (0.8.3 instead of 0.8c) + * #save and #load are now safe even in case of errors + (example: `disk full') + * hitting a #bind-ed key now echoes the corresponding command + only if #echo is on + * updated term.c (terminal handling code) and tel.c (telnet code) + with files from cancan 2.6.0b (yes, I shamelessly copied them) + No external changes anyway (unless I introduced some bugs) + note: beam.c NOT updated/copied + * 'follow' standalone mini-program added (see README.follow) + * #key is now explicitly stated not to support editing keys. + They cannot be added cleanly without rewriting the line-editing code + from scratch ('#key up' and '#key return' give the biggest problems) + and I don't have the time for that right now + * blink attribute added + * Now can use multiple attributes in #mark, #hilite, #color + example: #mark *An Orc*=inverse bold blue on red + Note: bold, blink, underline and inverse must appear BEFORE colors + * fixed some bugs: + * changed "VERSION" to "POWWOW_VERSION" in powwow.c. + It seems some compilers use VERSION for internal purposes... + * #wrap mode was discarding lines containing only escape sequences + (example: color codes coming from the MUD) + * #hilite was restoring hilight attributes after EVERY line + coming from the MUD + * self-recursive aliases were causing crash after 100 loops instead + of trapping error and reporting '#error: stack overflow' + (not always, and not on all OS). Now they are completely safe. + Note: they still eat 1MB of memory (10K per loop - released + immediately after) + +Changes from 0.8a to 0.8b (Massimiliano Ghilardi) + * hexadecimal numbers added (and in any other base) + can be used only from calculator, prefix is # + * '#write' command added + * fixed a bug with #nice affecting #load + now #load places actions/marks in memory in the same order as + config file, indipendently from #nice value. + Also, default #nice changes from 1 (top) to 0 (bottom) + * fixed a bug in #save that sometimes caused crashes and destroyed + config file + * now word completion (issued with TAB key) checks + word completion list _before_ built-in commands + +Changes from 0.8 to 0.8a (Massimiliano Ghilardi) + * remind me NEVER to work on Sunday, because I filled version 0.8 with + these bugs (now fixed): + - some debugging stuff was not deleted from official version + - deleting a named variable could cause a crash + - creating a named variable was giving a message even while reading + a definition file + - #settimer was not working due to a change in version 0.8 + - forgot to say that #map variable was added + * #rand, #map and #timer variables renamed rand, map and timer + (removed the #) - sorry for the change but it was necessary. + * removed limit of 50 named variables of each kind (numeric and string) + now the only limit is the memory available + +Changes from 0.7b to 0.8 (Massimiliano Ghilardi) + * #mark now accepts wildcards ($ for a single word, & for a string) + * named variables are now supported + * #assign renamed #var (I never liked the name 'assign' ...) + also, #var can be used to delete variables from memory + * #nice command added. It sets/shows priority of new actions/marks + +Changes from 0.7a to 0.7b (Finn Arne Gangstad) + * make_it now also works for sunos 5.x, irix 5.x and hpux 9.x + +Changes from 0.7 to 0.7a (Massimiliano Ghilardi) + * fixed a _HUGE_ hole in security: $n in actions was matching also ; + (but not spaces) so robotic actions gave a chance to other players + to force you (*AAARGH*) + * startup changed: now powwow does not clear screen when executed, + but jumps to the end of screen (this avoids mess in the first lines + you get from the mud) + +Changes from 0.6d to 0.7 (Massimiliano Ghilardi) + * finally fixed the unpleasant bug of auto-wrap making confusion when + receiving lines that contain escape sequences + (the fix in 0.6d was far from satisfactory) + * high-intensity colours added (for the terminals that support them) + * #assign can be used to put the contents of a variable on input line + * number of global variables raised to 50, max lenght of string + variables raised to 512 bytes + * #settimer command added, '#time' variable changed into '#timer' + * fixed a bug: math operator >= was wrong, worked as <= + +Changes from 0.6c to 0.6d (Massimiliano Ghilardi) + * break key now is also used to stop command-parsing. Useful to stop + long or infinite loops without exiting from powwow. + * #stop command added. It disables all active delayed commands. + * #mark now works also with prompts (was not implemented before) + * fixed an ancient bug with #action not working on lines splitted into + multiple data packets by telnet. + * fixed two other ancient bugs: + #mark not working on auto-wrapped words + and auto-wrap making confusion when receiving lines that contain + escape sequences (only partially fixed to be honest) + * Now the unescaping is performed ALSO on quoted strings, when powwow + evaluates them. Thus there might be to update your definition file + if it contains escapes placed in strings. + +Changes from 0.6b to 0.6c (Massimiliano Ghilardi) + * If you have problems with #rand, random() and srandom() (typically + your compiler is unable to find the functions) you can define + NO_RANDOM at compile time. (temporary solution) + * Now also editing keys can be redefined + * #assign command added (same syntax of #print, #send and #exe) + * Now you can specify start and end line of a file or output of Bourne + shell command when using #print, #send, #exe, #emulate or #assign + * #debug command added (try it in test mode...) + * Now #echo, #info, #speedwalk and #debug also accept 'on' or 'off' + +Changes from 0.6 to 0.6b (Massimiliano Ghilardi) + * #emulate command added (same syntax of #print, #send and #exe) + * now also prompts can be intercepted by #actions + (but cannot be 'gagged') + * powwow can run in test-mode without being connected to a MUD + +Changes from 0.5 to 0.6 (Massimiliano Ghilardi) + * more debug work + * #exe, #send and #print extended to use shell commands and files + Also, #send replaces #read + * #time variable added + * #rand function added + * #connect now supports a different remote host for each connection + (i.e. you can now play on different MUDs with the same invocation + of powwow) + + Ideas coming from Cancan 2.5.1c and implemented on powwow 0.6: + + * output to the remote host is buffered up and sent all at once in the + main loop, to reduce the number of network packets. Long aliases + might benefit from this, as would repeated commands (#10 buy bread). + * #help now works on commands. A help file is needed and provided. + * new command: #record, records lines you type in a file + * source changed so path for helpfile is taken from environment + variable POWWOWHELP (if this variable is not defined, powwow looks + in current directory) + * to print the message of the day, must define MOTDFILE in compiling + with the name (and complete path) of the file containing the message + * Now compiles on BSD/386 as well, automatically detected by make_it + +Changes from 0.4 to 0.5 (Massimiliano Ghilardi) + * Heavy debug work, since 0.4 was an alpha version + (it is not a good idea to place here the huge list of bugs fixed...) + * added #history to list/execute commands in history + Note: #history commands are not placed in history... + * now internal commands can be abbreviated, for example #al can be used + istead of #alias. However, internal commands are still completed + using TAB + +Changes from Cancan 2.5.0b to powwow 0.4 (Massimiliano Ghilardi) + * Inline calculator, with both global and local variables, and C-like + syntax + * added commands #(), #print, #send, #exe to use inline calculator + * added commands #if-#else, #for and #while. + * added #key, #save, #load, #save, #lines, #info, #echo, #compact, + #net, #clock, #time + * added #in and #at to define/edit delayed commands + * #mark and all attrib-related commands now accept also the attribute + 'none' + * #marks and #actions now are not automatically sorted (to sort them, + define SORT in compiling). #aliases and #binds instead are always + sorted. + * #aliases can be self-recursive now (it is potentially dangerous, + powwow will not enter a very long - but not infinite - loop) + * Must not escape ';' anymore to place multiple commands in #alias, + #action or #bind. Instead, multiple commands must be surrounded by + braces, { and } + * #action changed syntax (not need double quotes anymore, but need one + of > < + - = before label) See powwow.doc for details + Lines matched with #action are not printed on screen automatically, + must use a #print to echo them + * #gag is suppressed (not needed anymore), and #add is now a command + * Escaping technique changed. Now unescaping '\\\#' gives '\\#' (i.e. + remove one \ each time), and you can also escape \, in this way: + \` gives \ alone, \`` gives \` and so on. So for example, if you + want to place a \ at the end of an #action pattern, you must write + \` , to avoid escaping the = after the pattern + * Some bugs of Cancan fixed (small things, expecially wrapping) + +Changes from 2.5.0a to 2.5.0b (Finn Arne Gangstad) + * Fixed bug with client aborting when window was resized. + +Changes from 2.5.0 to 2.5.0a (Finn Arne Gangstad) + * Various tweaks to make it compile on most systems. + +Changes from 2.4.4 to 2.5.0 (Mattias Engdegård) + * the length of the prompt is now correctly calculated + even if it contains escape sequences (for muds with coloured prompt). + * built-in commands are always completed with tab and aren't stored in + the word list + * #hilite and #mark now accept general attributes: ansi colours and + bold, underline, inverse. + * the #action command has changed syntax; now double quotes are + required around the pattern, but they can be named. Actions can be + turned on and off. + * the keydefs list contains all keyboard bindings. The #bind command + can define new keys. + * the #alias, #action, #bind and #mark commands can now put a + definition line in the input buffer for easy editing. + The keys M-p and M-n are no longer used. + * some new files, new source module discipline with external + declarations only in header files. + * added the file `Hacking' with some advice. + * mapping functions cleaned up. #map now displays ssss as 4s. + * the definition file is tagged with a file version, to make it easier + to recognize older save formats. + * cancan now displays a motd file whose location is set at compile + time (see Makefile). + * define TELNETBUG to work around an NCSA telnet 2.2 colour bug. + #stdcolour can be used to set the background colour if TELNETBUG is + defined. + +Changes from 2.4.3 to 2.4.4 (David Gay) + * telnet window size option supported + +Changes from 2.4.2 to 2.4.3 + * added term support + * added #hilite to hilite user entered text + * added #mark and #unmark to mark special keywords... + * changed #identify to allow it to send alias' or commands to the + mud when beginning/ending an editing session. + * changes the Makefile a bit to support termcancan + +Changes from 2.4.1 to 2.4.2 + * Added multiple-session support with following # commands: + '#connect', '#zap', '#snoop', '##' + * Added numeric keypad movement, keypad sends commands + n,e,s,w,u,d and exits.. (not on all systems) + * Easier editing of actions with meta-p and meta-n (not on all systems) + * Changed the 'make_it' script a bit, so that it echoes the make + command it executes. + +Changes from 2.4.1 to 2.4.1b + * Improved modularity of source, new files cmd.c, cmd.h + +Changes from 2.4.0 to 2.4.1 + * Changed & in actions to match a single word for backward + compatibility. &0..&9 still match multi-worded text. + * Now compiles on HP-UX (at least HP-UX 9.01A ) + * Included a 'make_it' script that automatically compiles cancan for + Linux, IRIX, AIX, ULTRIX, DolphinOS, SunOS and HP-UX sytems. + +Changes from 2.3.6 to 2.4.0 + * Extended param substitution for & to &0..&9. + * Added '&&' syntax for delayed param substitution. + * Added '#init' command to send initialization string on connect. + * Added '#speedwalk' to toggle speedwalk on and off. + * Added '#map' with automapping. + * Added '#retrace' to retrace steps. + * Added sorting for alias and action lists, which is disabled if + compiled with -DNOSORT. + * Added compile option -DNOSHELL to remove '#!' shell escape function. + +Changes from Cancan 2.3.5 to 2.3.6 + * Fixed a bug with MUME's spinning delay bars and word wrap. + * & can now be escaped. This allows for aliases that create aliases, + and other things. + * Added this change log (not too early) + * Checks the window size after being suspended, in case it was + changed. + * Lines longer than screen width because of invisible spaces and/or + trailing CR:s are not unnecessarily wrapped. + |
