HISTORY
=========
Changes from 5.38 to 5.39 (public release)
-------------------------
- New builtin variable "_timeout" (in microseconds) sets maximum response
time for terminal to answer WINDOW STATUS REQUEST (for window bounds).
Defaults to 1 (for local usage), must be set to higher value for remote
connections. Only used, if window pointer is not available.
- Removed command line length limitation (140 chars) for ARexx scripts that
ends with ".rexx" but are started without the trailing ".rexx".
- Removed command line length limitation (518 chars) for ARexx scripts and
external shells (#! in first line), this was a limitation in AmigaOS'
System() function. DOS scripts still have this limitation, because you
cannot RunCommand() "execute".
- Not only "*" and "?" but also "[" and "]" recognized as AmigaDOS pattern.
(that means, to use "[" and "]" you must quote (") or escape (\) them!)
- ... and much more workarounds for serious bugs in DateToStr() and Locale
- Fixed bug: making an assign to an executable and calling the executable
by its assign crashed machine.
- Fixed bug: builtin command "cp" sometimes used already freed memory for
generating error messages (resulted in some strange error messages)
- New flag for for command abbreviation ($_abbrev):
8, search DOS path-list if command wasn't found in Cshell's internal
program hash list (see "rehash" command)
Changes from 5.37 to 5.38 (internal beta release)
-------------------------
- CTRL-D now shows matching files if current word is not a directory.
(if directory then shows contents of directory -- as usual)
In its current implementation this may have unexpected side effects
if current word is already a pattern.
- Class definition for AmigaE in class.sh
[thanks to Joseph E. Van_Riper III]
- Now internal timer (eg, %e in the titlebar) not set to zero when a null
command is encountered. (same for return code, %x in titlebar)
- The idea of always using the variable "_dirformat" for "dir" wasn't a
good idea. So, "_dirformat" is only used if option -z is given (when
"_dirformat" is unset then use first argument as format string).
- New control-code for line-editing: "^V" (ctrl-v) quotes next char.
- New builtin variable "_kick" holds version number of Operating System.
- Builtin command "assign" now prints volume name if assign points to
an unmounted volume (eg, a removed floppy disk) and doesn't pop up
a requester "Please replace volume ..."
- It was a stupid idea to force redirecting of all Cshell-related
system requesters to CSH's screen, because requester windows inherit
the window title of their "initiator". They appear now again on your
default public screen.
- Fixed serious bug (crashed machine) with redirection and launching
programs into background. (files closed twice)
Known bug: it's still not possible to run pipes into background...
- When running programs into background (run, rback, &), internal commands
and aliases are recognized and executed with "csh -c". Aliases WON'T be
resolved on this level so they must be declared in .cshrc to run them
into background.
- Execution of Rexx-Scripts (without trailing ".rexx") and any other program
with "#! my_prog" or ";! my_prog" in first line of script now possible
also from DOS search path and not only $_path.
- New builtin variable "_mappath" (see manual), enables pathname-mapping for
commands if script starts with "#!" or ";!" in first line. Converts Unix
pathes like "/usr/..." to "usr:...".
- New option "-w" for Cshell, don't use window pointer (useful for KingCON).
- New option "-V" for Cshell, send only VT100 compatible control sequences
- Internal variable "o_vt100" now used (if option -t or -V is set),
don't send control sequences that are not VT100 compatible (eg,
special Amiga control sequences).
Changes from 5.36 to 5.37 (public release)
-------------------------
- Builtin command "mkdir" now strips off trailing slash (if any).
- Builtin command "chmod" now supports "a" for all bits (ugo),
and if no ownership-bit is specified "chmod" really modifies
only the user-bits (as stated in the doc) and not all bits.
- Builtin commands "chown/chgrp" now also run under AmigaOS 2.0+
(direct DOS packets), not only under AmigaOS 3.0+ (SetOwner).
[thanks to Carsten Heyl]
- No requester "please insert volume ..." when you press return
and your current directory is on an "unmounted" volume
(eg, a removed floppy disk).
- Builtin command "dir" now uses contents of variable "_dirformat"
(if set) automatically as default output format (option -z not
neccessary for _dirformat anymore). Option -z (followed by an
argument with format string) can now be used again for another
custom format for current call as in Cshell 5.19 and before.
[thanks to Laurent Faillie for his letter]
- Builtin command "protect" was broken in beta-version 5.36.
- Source code now "indent" clean.
(some warnings on first run, but no errors)
- New option "-c" for builtin command "qsort": be case-sensitive.
Changes from 5.35 to 5.36 (internal beta release)
-------------------------
- Now output in "path -r" only if at least 1 memory block could not be
freed.
- Fixed layout bug in "rm -r <wildcard>" if one or more items could not
be removed.
- Fixed serious bug in "rehash", access to already freed memory under
certain circumstances. (always think twice before using "char ***" ;-)
- Manual entry for builtin command "relabel".
- Error checking code for all NameFromLock() calls.
- Now 100% Commodore-compatible version string.
- Now @rnd( ) accepts optional seed parameter.
- Fixed bogus output for NULL pointers in pattern-matching-routine.
- Fixed bug in "rehash", recognition of executables was broken.
- Now multiple drive names are allowed for "diskchange".
- Now @age() returns null-string if file was not found (instead of 99999).
[thanks to Gary Duncan]
- New function @age_mins() returns age of file in minutes.
[thanks to Gary Duncan]
- Now requesters appear on same screen as CSH's window.
- Variable "_abbrev" now handled somewhat different: it enables/disables
the different modes of command-abbreviation. See manual for details!
- Output of "dir -k" and "dir -i" (show classes) looks much nicer now.
- Added class "gzip" to csh:class.sh.
- Added support for MultiUser. %U in prompt/titlebar shows current user
of CSH. Out-comment "#define MULTIUSER_SUPPORT 1" in shell.h to compile
without MultiUser stuff.
[thanks to Magnus Lilja]
- New builtin commands "chown" and "chgrp".
- Builtin command "chmod" now supports User/Group/Other bits.
- New placeholders for custom output format (option "-z"),
"%F" shows group/other bits, %U shows user-id, %G shows group-id.
Changes from 5.34 to 5.35 (public release)
-------------------------
- Now CSH executes "s:.logout" on exit.
New option "-L" (noLogout) disables sourcing of "s:.logout".
- Fixed option "-n" in builtin command "dir", never worked before.
- Some minor layout changes in builtin command "help".
- Builtin command "window -q" (query) shows public screen names.
- New/Changed options for builtin command "strings".
(not compatible with previous versions!)
- More sophisticated memory-cleanup for builtin command "path -r" (reset).
- New option "-M" for CSH, don't clear menus (especially for KingCON).
- Support for soft-links in builtin command "dir".
[thanks to Carsten Heyl]
Changes from 5.33 to 5.34 (internal beta release)
-------------------------
- New section SCROLLING in the manual (at the end). Read it !
- New variable "_prghash" holds filename where program hash list
is loaded from and saved to.
- Now CSH also finds programs in resident list if they start with "C:"
(even if there is no corresponding program in C: directory).
This is for compatibility reasons (Commodore Shell).
- In previous versions CSH aborted the commandline if one pattern
did not match. Now CSH only aborts if all patterns does not
match.
- Totally new meaning of variable "_nomatch". It's now unset by
default and if you set it then CSH will _not_ abort if all
patterns does not match.
- Added option "-m" to CSH, sets "_nomatch" variable.
(for compatibility reasons)
- Fixed bug in date command (s/r options).
[Gary Duncan]
- New option -a for "copy" command, don't clear archive bit.
[Gary Duncan]
- Rewritten code for "window -q", no longer crashes system.
- New option "-w" for builtin command "window".
(ignore window width for option -q, so that very long window/screen
titles are printed completely)
- Input/output redirection with "<>", the file must be either
"NIL:" or an interactive file.
- New variable "_cquote" enables Commodore-style handling of
quotation marks (eg, for use with ReadArgs);
variable is unset by default (UNIX-style handling of quotes).
- Increased some (very small) buffers in "ls" code (could crash
machine), line limit is now around 1000 chars per line. Had
to increase internal stack size to 17500.
Changes from 5.32 to 5.33 (internal beta release)
-------------------------
- New builtin command "rehash", buffers programs in DOS search path
and offers program name completion (ESC-p, ESC-P). Two new "completion
functions" for keymaps:
36, CompPrg1 Insert first matching program (or cycle)
37, CompPrgAll Shows all matching programs
- Fixed input-stream problem for DOS scripts.
- Kludge for running DOS scripts from devices with spaces in their name.
- Fixed Enforcer hit in "set" command (eg, "set a ="),
just curious: this Enforcer hit was misinterpreted by an user to be
a bug in "_every" variable and accidently I found another bug there
which caused CSH to ignore "_every" if the previous shell command was
aborted (^C)
- Fixed Enforcer hit: "unset _path"
- Builtin command "date" can now read battery-backed up clock directly
[thanks to Gary Duncan]
Changes from 5.31 to 5.32 (internal beta release)
-------------------------
- Removed "No match" output if "dir" was used on empty directories.
This was a feature, not a bug. But misunderstood by most users.
- New "edit function" for keymaps: 29, insert last word of previous line
(e.g. "keymap 0 12=29" assigns that function to CTRL+L)
- Option "-q" of builtin command "rm/delete" didn't work in previous
versions. Now aborts as documented.
This does _not_ affect non-matching wildcards, use "_nomatch" instead.
- Checking of requested stack size (builtin command "stack").
- Builtin command "mem" now calls AllocMem(0x7fffffff,0) ten times
to flush unneeded memory. (similar to "avail flush")
- fixed possible rounding bug in "itok()", caused display of wrong size
for harddisk partitions around 1 GB etc.
