- #print Dwarves
-
-2005-10-21 23:20 bpk
-
- * tcp.c: Added some casts because byte is unsigned char and some

- hand mostly
-
-2005-03-21 18:16 bpk

-
-2005-03-12 02:43 bpk

-
-2005-03-12 00:41 bpk
-
- * cmd.c: Changed the #module command to handle searching multiple

-
- * Initial import of stock powwow 1.2.5
-
-Changes from 1.2.4 to 1.2.5 (Massimiliano Ghilardi, ...) 21 Jan 2002
- * Added append-mode to #capture: use #capture >file-name
- * Cleaned #spawned commands interface: text they print on
- standard output *MUST* terminate with a newline ('\n')
- in order for powwow to execute it.
- * Fixed missing #include <time.h> in main.h.
- * Fixed broken matching of #mark patterns starting with $
- * Added the following user-contributed patches:
- * Put also 1-char lines into history;
- * Do not capture/movie data coming from spawned commands;
- * Fixed a bug in command parser.
-
-Changes from 1.2.3 to 1.2.4 (Massimiliano Ghilardi) 24 May 2000
- * Added support for IAC GA as end-of-prompt marker.
- * Added #request [prompt][editor][all]
- * Fixed missing/slow prompt redrawing under some circumstances
- if #isprompt <number> was used.
-
-Changes from 1.2.2 to 1.2.3 (Massimiliano Ghilardi) 18 Jan 2000
- * Fixed `#spawn' command that was completely screwed up.
- Also fixed CTRL-C not to kill spawned commands.
- * Sending/receiving data to/from spawned commands erased the prompt
- instead of reprinting it. Fixed.
- (If you don't like powwow to show the prompt before executing
- lines from spawned commands, set #option +compact)
-
-Changes from 1.2.1 to 1.2.2 (Massimiliano Ghilardi) 10 May 1999
- * Fixed `#delim custom' to accept whatever character as delimiters.
- Previously stopped before the first word-delimiting char (argh!)
- * Fixed screen corruption when doing some editing functions
- (&del-word-right, &del-word-left, &complete-word, &complete-line,
- parentheses flashing) while data comes from the MUD.
- * Fixed a line redrawing bug when inserting chars on terminals
- with VT100-like wrapglitch.
- * Fixed SEGFAULT on #send, #emulate, #exe of a numeric expression.
- * Fixed stupid SEGFAULT when cancelling an editing session.
- * Fixed sending/receiving latin-1 '\377' (ASCII char 255) as IAC IAC
- to conform telnet protocol, both directly and inside MPI messages.
- * Fixed matching #actions, #prompts and #marks on MUD data splitted
- into multiple fragments.
- * Fixed line length calculation when receiving '\r' in the middle
- of a line.
- * Fixed extra prompt redrawing in #option +compact mode.
- * Added #option sendsize and #option autoclear.
- Changed default not to send window size upon connecting.
- (if the MUD asks it, the window size is sent anyway)
- Use #option +sendsize to automatically send it when you connect.
- * Added command #rawsend.
- * Removed bits of ANSI code giving problems
- with really picky non-ANSI compilers
-
-Changes from 1.2.0 to 1.2.1 (Massimiliano Ghilardi) 20 Nov 1998
- * Fixed a typo in Makefile.
- * Reversed order of saved #history lines.
- * Fixed out-of-bound array accesses in tcp_find() and tcp_show()
- which could give SEGFAULT on #connect, #snoop and #zap.
- * Fixed buggy loop in saving #history in definition file that could
- create a huge temporary file, filling the filesystem.
- * Fixed sporadic SEGFAULT when hitting backspace and some other
- editing keys.
- * Math operator `?' could freeze due to buggy code.
- Systems providing GNU memmem() didn't experience the problem
- as it was used instead of my replacement code.
- * Enhanced support for terminals with VT100-like wrapglitch:
- on them, the rightmost character of every line is used too.
- * Fixed wrapping in #printing strings containing ASCII chars > 127
- when #option wrap is on.
- * Fixed incorrect drawing of prompt and command line under some
- circumstances.
- * Fixed wrong wrapping of lines immediately after the prompt
- in #option +wrap mode.
- * Removed extra newlines sent after each line in `#send <filename'
- and `send !command'.
- * Fixed a few off-by-one errors causing corruption in #movie/#capture
- and (reprint) buffers.
- * Powwow now discards all \r received immediately before or after \n,
- to avoid troubles when strange data comes just before the prompt.
- * Changed MPI key to `unsigned int' because MUME uses a 32 bit
- unsigned value for it.
- * Cleaned up remote file editing not to leave stale files in /tmp.
- * Cleaned up multiple connections support:
- Fixed spurious `#too many open connections' errors.
- Fixed prompt drawing glitches when getting data from subsidiary
- connections.
-
-Changes from 1.1.7 to 1.2.0 (Massimiliano Ghilardi) 05 Oct 1998
- * Copyright change. Powwow is now GPL-ed.
- * Version number bump. I hope there aren't many bugs left.
- If you are coming from 1.0.x versions, read this file and powwow.doc
- carefully, many things have changed!
- * Fixed double-newline printing after each line if #option +wrap
- was set.
- * Suppressed useless reprinting of files sent back to MUD
- using MUME remote editing protocol.
- * Updated a few details in docs.
- * Some old compilers choked on bits of ANSI code. Fixed.
- * Fixed extra newline after prompt in #movie and #capture
- when #setvar buffer is not zero.
- * Fixed extra \r at beginning of a line under rare circumstances.
- * #delim now unescapes the custom delimeters.
- * Added missing close() when remote host closes connection.
- * Rewrote the code to merge lines received in two (or more) fragments.
- * Added `#help warranty' and `#help copyright' to conform GPL :-/
-
-Changes from 1.1.6 to 1.1.7 (Massimiliano Ghilardi) 15 Sep 1998
- * Changed meaning and effect of #prompt and #isprompt.
- If you used them, re-read their docs in powwow.doc!
- * Alias names containing spaces are now rejected too.
- Relaxed rules a little, unbalanced () {} or ""
- now just print a warning instead of causing an error.
- * Added #option reprint.
- * Old #prompts were not removed on #load. fixed.
- * Fixed SEGFAULT when chaining very long strings:
- #("foo..." + "bar...")
- * Fixed small compiling problems on some platforms.
- * Fixed an off-by-one error in math operator >:
- * Fixed math operator `=' bug on copying empty strings.
- * Fixed a crashy bug in #reset var.
- * Fixed some quirks in unescaping strings:
- ending backslashes caused SEGFAULT,
- sequences like \\\``` were unescaped incorrectly.
- * Fixed incorrect code in #mark and #action that
- mismatched patterns containing two or more wildcards.
-
-Changes from 1.1.5 to 1.1.6 (Massimiliano Ghilardi) 03 Sep 1998
- * Added circular backbuffer for #capture and #movie.
- Can be enabled/disabled/resized with #setvar buffer.
- * Sanitized aliases: powwow now rejects alias names containing
- unbalanced special chars ""(){} . 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. If #alias foo=\\bar
- then `foo' now sends `\bar' instead of `bar'.
- * Fixed a compatibility problem when reading #binds of new savefiles
- using old versions of powwow.
- * Fixed some problems with #var on numbered variables.
- * Fixed #internal error, selflookup_sortednode() failed!
- that affected 1.1.5
- * Fixed SEGFAULT upon #exe \; (introduced in 1.1.5).
- * When getting data from the MUD after a prompt which set #isprompt
- the data is now printed as a separate line even if it doesn't start
- with a newline. 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.
