\fP] Always use readline, regardless of \fIcommand\fP's terminal settings. Use this option you want to use rlwrap with \fIcommand\fPs that already use readline, e.g. to get \fBrlwrap\fP's history and completion. \fBNB\fP: With this option, rlwrap will echo (and save) passwords, unless you give \fIcommand\fP's password prompt as an argument. .OA \-a \-\-always-readline Password: .TP .OL \-A \-\-ansi-colour-aware Prompts that use colour will confuse rlwrap, especially at the end of long input lines. This option will make rlwrap behave in such cases. If the prompt contains anything fancier than ANSI color codes, this option may actually make things worse. .TP .OL \-b \-\-break-chars \fI
\fP Consider the specified characters word-breaking (whitespace is always word-breaking). This determines what is considered a "word", both when completing and when building a completion word list from files specified by \fB\-f\fP options following (not preceding!) it. Default list (){}[],+-=&^%$#@"";|\\ Unless -c is specified, \" twice " to keep emacs happy :-( / and \. (period) are included in the default list. .TP .OL \-c \-\-complete-filenames Complete filenames (filename completion is always case-sensitive, even with the \-i option) .CW .TP .OL \-C \-\-command-name \fI
|
\fP Use \fIcommand_name\fP instead of \fIcommand\fP to determine the names of history and completion files, and to initialise readline (as specified in ~/.inputrc). A numeric argument N means: use the Nth argument counting backwards from the end of the argument list .TP .OL \-D \-\-history-no-dupes \fIn\fP How agressively to weed out duplicate entries from the input history. If \fIn\fP = \fB0\fP, all inputs are kept in the history list, if \fIn\fP = \fB1\fP (this is the default) consecutive duplicates are dropped from the list, while \fIn\fP = \fB2\fP will make \fBrlwrap\fP drop all previous occurrences of the current input from the list. .TP .OL \-f \-\-file \fIfile\fP Split \fIfile\fP into words and feed them into the completion word list. This option can be given more than once, and \fIadds\fP to the default completion list in $RLWRAP_HOME or @DATADIR@/rlwrap. .TP .OL \-F \-\-history-format \fIformat\fP Append \fIformat\fP to each history entry, replacing the following printf-style conversion specifiers: \fB%D\fP by \fIcommand\fPs working directory, \fB%P\fP by the current prompt, \fB%C\fP by the \fIcommand\fP name, and all remaining format specifiers recognised by \fBstrftime (3)\fP \fIformat\fP should start with one or more non-space characters, which will be used to recognise and strip off the appended \fIformat\fP from recalled history items. .TP .OL \-h \-\-help Print a short help message. .TP .OL \-H \-\-history-filename \fIfile\fP Read command history from \fIfile\fP (and write it back there if \-\-histsize >= 0) .TP .OL \-i \-\-case-insensitive Ignore case when completing (filename completion remains case-sensitive). This option has to come before any -f options. .TP .OL \-l \-\-logfile \fIfile\fP Append \fIcommand\fP's output (including echo'ed user input) to \fIfile\fP (creating \fIfile\fP when it doesn't exist). .TP .OL \-n \-\-no-warnings Don't print warnings. .TP .OL \-m \-\-multi-line [\fI
\fP] Enable multi-line input using a "newline substitute" character sequence (" \\ ", [space-backslash-space] by default). Newline substitutes are translated to newlines before sending the input to \fIcommand\fP. With this option, you can call an external editor $RLWRAP_EDITOR on the (expanded) current input with the \fIrlwrap_call_editor\fP key (CTRL-^ by default) .OA \-m \-\-multi-line ';;' .TP .OL \-p \-\-prompt-colour [\fI
\fP] Use ANSI-conformant
to colour any prompt displayed by \fIcommand\fP. All output that doesn't end in a newline is considered a "prompt" by \fBrlwrap\fP (but only if \fIcommand\fPs terminal is in cooked mode) - this may not be what you want. Prompts that are too long, or contain (colour) escape sequences, are not coloured. This option implies \-\-ansi-colour-aware. \fI
\fP has the form
;
[;
] Example: \-p'0;31' will give a red prompt on the current background (this is the default when no argument is given). Google for 'ANSI color' to learn more about colour codes. .OA \-p \-\-prompt-colour '0;31' .TP .OL \-P \-\-pre-given \fItext\fP Start \fBrlwrap\fP with \fItext\fP in edit buffer (this will automatically set the \-\-always-readline option). Use this for default user input in "one-shot" situations like the following replacement for the \fIread\fP shell command: .nf rlwrap -H past_dinners -f toppings -P "pizza"\\ sh -c 'echo -n "please order: "; head -n 1 > dinner' prepare $(dinner) .fi .TP .OL \-q \-\-quote-characters \fI
\fP Assume that the given characters act as quotes, e.g. when matching parentheses. Take care to escape the list properly, or else your shell will become confused (for example: \-q "\\"'", which happens to be the default) .TP .OL \-r \-\-remember Put all words seen on in- and output on the completion list. .TP .OL \-s \-\-histsize \fI
\fP Limit the history list to N entries, truncating the history file (default: 300). A negative size -N means the same as N, but treats the history file as read-only. .TP .OL \-v \-\-version Print rlwrap version. .SH SPECIAL KEYS .TP .B Control + O Accept the current line, but don't put it in the history list. This action has a \fBreadline\fP command name \fIrlwrap_accept_line_and_forget\fP .TP .B Control + ^ Use an external editor to edit the current input (this will only work if the \-m option is set). This action has a \fBreadline\fP command name \fIrlwrap_call_editor\fP .PP If you don't like these keybindings, \fBrlwrap\fPs special keys (all keys, in fact) kan be re-bound by including a line like the following in \fB~/.inputrc\fP: .IP "" "\eM\-\eC\-m":rlwrap_accept_line_and_forget # ESC-ENTER .TP c.f. the \fBreadline(3)\fP manpage for more about re-binding keys .SH ENVIRONMENT .TP \fBRLWRAP_HOME\fP: directory in which the history and completion files are kept. .TP \fBRLWRAP_EDITOR\fP (or else \fBEDITOR\fP, or else \fBVISUAL\fP): editor to use for multi-line input. Example: .PP .nf export RLWRAP_EDITOR="emacs -nw" export RLWRAP_EDITOR="vi +%L" .fi .PP The last example is the default; %L and %C are replaced by line and column numbers corresponding to the cursor position in \fBrlwrap\fPs edit buffer .SH SIGNALS .PP A number of signals are forwarded to \fIcommand\fP: HUP INT QUIT USR1 USR2 TERM and (by way of resizing \fIcommand\fPs terminal) WINCH. Some care is taken to handle TSTP (usually a result of a CTRL-Z from the terminal) sensibly. If \fIcommand\fP changes the keystrokes that send a particular signal from the keyboard (like emacs, which uses CTRL-G instead of CTRL-C) \fBrlwrap\fP will do the same. When \fIcommand\fP is killed by a signal, \fBrlwrap\fP will clean up, reset its signal handlers an then commit suicide by sending the same signal to itself. This means that your shell will see the same exit status as it would have seen without \fBrlwrap\fP. .SH REDIRECTION When the standard input is not a terminal, editing input doesn't make sense, so \fBrlwrap\fP will ignore all options and simply execute \fIcommand\fP. When stdout (or stderr) is not a terminal, rlwrap will re-open it to /dev/tty (the users terminal) after it has started \fIcommand\fP, so that \fIcommand\fPs output is redirected as expected, but keyboard input and \fBrlwrap\fP error messages are still visible. The upshot of this is that \fBrlwrap\fP \fIcommand\fP behaves more or less like \fIcommand\fP when redirecting. .SH EXIT STATUS non-zero after a \fBrlwrap\fP error, or else \fIcommand\fP's exit status. \fBrlwrap\fP will always leave the terminal in a tidy state, even after a crash. .SH FILES \fBrlwrap\fP expects its history and completion files in $RLWRAP_HOME, but uses .dotfiles in the users home directory if this variable is not set. This will quickly become messy if you use \fBrlwrap\fP a lot. .TP $RLWRAP_HOME/\fIcommand\fP_history, ~/.\fIcommand\fP_history History for \fIcommand\fP .TP $RLWRAP_HOME/\fIcommand\fP_completions, ~/.\fIcommand\fP_completions Per-user completion word list for \fIcommand\fP. \fBrlwrap\fP never writes into this list, but one can combine \fB\-l\fP and \fB\-f\fP options to to simulate the effect of a \fB\-r\fP option that works across invocations. .TP @DATADIR@/rlwrap/\fIcommand\fP System-wide completion word list for \fIcommand\fP. This file is only consulted if the per-user completion word list is not found. .TP $INPUTRC, ~/.inputrc Individual \fBreadline\fP initialisation file (See \fBreadline\fP (3) for its format). \fBrlwrap\fP sets its \fIapplication name\fP to \fIcommand\fP (unless you use the \fB\-C\fP option), enabling different behaviours for different commands. One could e.g. put the following lines in \fB~/.inputrc\fP: .RS .nf .if t .ft CW $if coqtop set show-all-if-ambiguous On $endif .if t .ft P .fi making \fBrlwrap\fP show all completions whenever it runs \fIcoqtop\fP .SH BUGS \fBrlwrap\fP can try, but often fails to, handle prompts that contain control characters. A client that uses anything more than simple ANSI color codes will confuse rlwrap. The first thing you will notice in such cases is the cursor wrapping back on the same line before it has reached the right margin. Prompt colouring (using the \-p option) is not very robust. This is why long prompts are never colourised. vi mode doesn't work well with terminals that cannot move the cursor up (A warning will be printed at startup) Pasting large amounts of text into \fBrlwrap\fP will mess up the screen. However, \fIcommand\fP should receive the pasted text correctly. .SH VERSION This manpage documents rlwrap version @VERSION@ .SH AUTHORS The readline library (written by Chet Ramey) does all the hard work behind the scenes, the pty-handling code has been taken practically unchanged from rxvt-2.7.10 (currently maintained by Geoff C. Wing), and completion word lists are managed by Damian Ivereighs libredblack library. The few remaining lines of code were written by Hans Lub (hlub@knoware.nl). .SH SEE ALSO .TP .B readline(3) \" Local variables: \" mode:nroff \" End: rlwrap-0.30/doc/Makefile.am 0000644 0000764 0000764 00000000232 10470334674 012502 0000000 0000000 man_MANS = rlwrap.1 # EXTRA_DIST = $(man_MANS) CLEANFILES = $(man_MANS) rlwrap.1: rlwrap.man sed -e 's#@DATADIR@#$(datadir)#' rlwrap.man > rlwrap.1 rlwrap-0.30/doc/Makefile.in 0000664 0000764 0000764 00000024310 10740653320 012510 0000000 0000000 # Makefile.in generated by automake 1.10 from Makefile.am. # @configure_input@ # Copyright (C) 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, # 2003, 2004, 2005, 2006 Free Software Foundation, Inc. # This Makefile.in is free software;

I couldn't find anything like it when I needed it, so I wrote this one back in 1999. By now, there are a number of good readline wrappers around, like rlfe, distributed as part of the GNU readline library, and cle (http://kaolin.unice.fr/Cle/). rlwrap should be especially useful when you need user-defined completion (by way of completion word lists) and persistent history. Moreover, it should be portable across a fairly wide range of Unix systems (it works under cygwin as well) * HOW TO USE IT: If $
yields garbage like ^H and ^[[D whenever you try to edit input, or if you just want decent input history and completion, try: $ rlwrap [-options]
You then can edit
's input and recall the input history using the arrow keys. Input history is remembered accross invocations, separately for different
s. Typing !
will recall the last input line starting with
, CTRL-R will search the input history. With the -r and -f options you can specify the list of words which rlwrap will use as possible completions, taking them from a file (-f option) or from
's standard in/output. rlwrap monitors
's terminal settings, so that it can do the right thing when command asks for single keypresses or for a password. Commands that already use readline will always ask for (and get) single keypresses, which makes rlwrapping them rather pointless. However, if one uses the -a option, rlwrap will use its own line editing and history. Unforunately, in this case, rlwrap cannot detect whether
asks for a password. This can be remedied by giving the password prompt (excluding trailing space and possibly the first few letters) as an argument to the -a option. * EXAMPLES: Run netcat with command-line editing: rlwrap nc localhost 80 Run lprolog and use library1 and library2 to build a completion word list: rlwrap -f library1 -f library2 lprolog Run smbclient (which already uses readline), add all input and output to completion list, complete local filenames, avoid showing (and storing) passwords: rlwrap -cr -aPassword: smbclient '\\PEANUT\C' * INSTALLATION: Usually just # ./configure; make install See the INSTALL file for more information. * PARENTHESIS MATCHING This is not very clearly documented in readline's info or manpages, it should be on by default. It can be controlled by putting "set blink-matching-paren (off|on)" in your .inputrc * AUTHOR Hans Lub, hlub@knoware.nl * HOMEPAGE http://utopia.knoware.nl/~hlub/uck/rlwrap rlwrap-0.30/configure.ac 0000644 0000764 0000764 00000023204 10740653277 012176 0000000 0000000 dnl configuration script for rlwrap dnl Process this file with autoconf to produce configure. dnl dnl Copyright (C) 2000-2007 Hans Lub hlub@knoware.nl dnl dnl This file is part of rlwrap dnl dnl rlwrap is free software; you can redistribute it and/or modify it dnl under the terms of the GNU General Public License as published by dnl the Free Software Foundation; either version 2, or (at your dnl option) any later version. dnl dnl rlwrap is distributed in the hope that it will be useful, but dnl WITHOUT ANY WARRANTY; without even the implied warranty of dnl MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.
