+
+Basic Installation
+==================
+
+ These are generic installation instructions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. (Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.)
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You only need
+`configure.ac' if you want to change it or regenerate `configure' using
+a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system. If you're
+ using `csh' on an old version of System V, you might need to type
+ `sh ./configure' instead to prevent `csh' from trying to execute
+ `configure' itself.
+
+ Running `configure' takes awhile. While running, it prints some
+ messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ If you have to use a `make' that does not support the `VPATH'
+variable, you have to compile the package for one architecture at a
+time in the source code directory. After you have installed the
+package for one architecture, use `make distclean' before reconfiguring
+for another architecture.
+
+Installation Names
+==================
+
+ By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc. You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on. Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the `--target=TYPE' option to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+ Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+will cause the specified gcc to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+`configure' Invocation
+======================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+ Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+.Sh DESCRIPTION
+The
+.Nm
+library provides generic line editing, history and tokenization functions,
+similar to those found in
+.Xr sh 1 .
+.Pp
+These functions are available in the
+.Nm libedit
+library (which needs the
+.Nm libcurses
+library).
+Programs should be linked with
+.Fl ledit
+.Fl lcurses .
+.Sh LINE EDITING FUNCTIONS
+The line editing functions use a common data structure,
+.Fa EditLine ,
+which is created by
+.Fn el_init
+and freed by
+.Fn el_end .
+.Pp
+The following functions are available:
+.Bl -tag -width 4n
+.It Fn el_init
+Initialise the line editor, and return a data structure
+to be used by all other line editing functions.
+.Fa prog
+is the name of the invoking program, used when reading the
+.Xr editrc 5
+file to determine which settings to use.
+.Fa fin ,
+.Fa fout
+and
+.Fa ferr
+are the input, output, and error streams (respectively) to use.
+In this documentation, references to
+.Dq the tty
+are actually to this input/output stream combination.
+.It Fn el_end
+Clean up and finish with
+.Fa e ,
+assumed to have been created with
+.Fn el_init .
+.It Fn el_reset
+Reset the tty and the parser.
+This should be called after an error which may have upset the tty's
+state.
+.It Fn el_gets
+Read a line from the tty.
+.Fa count
+is modified to contain the number of characters read.
+Returns the line read if successful, or
+.Dv NULL
+if no characters were read or if an error occurred.
+.It Fn el_getc
+Read a character from the tty.
+.Fa ch
+is modified to contain the character read.
+Returns the number of characters read if successful, \-1 otherwise.
+.It Fn el_push
+Pushes
+.Fa str
+back onto the input stream.
+This is used by the macro expansion mechanism.
+Refer to the description of
+.Ic bind
+.Fl s
+in
+.Xr editrc 5
+for more information.
+.It Fn el_parse
+Parses the
+.Fa argv
+array (which is
+.Fa argc
+elements in size)
+to execute builtin
+.Nm
+commands.
+If the command is prefixed with
+.Dq prog :
+then
+.Fn el_parse
+will only execute the command if
+.Dq prog
+matches the
+.Fa prog
+argument supplied to
+.Fn el_init .
+The return value is
+\-1 if the command is unknown,
+0 if there was no error or
+.Dq prog
+didn't match, or
+1 if the command returned an error.
+Refer to
+.Xr editrc 5
+for more information.
+.It Fn el_set
+Set
+.Nm
+parameters.
+.Fa op
+determines which parameter to set, and each operation has its
+own parameter list.

+.Fn history_init .
+.It Dv EL_EDITMODE , Fa "int flag"
+If
+.Fa flag
+is non-zero,
+editing is enabled (the default).
+Note that this is only an indication, and does not
+affect the operation of
+.Nm .
+At this time, it is the caller's responsibility to
+check this
+(using
+.Fn el_get )
+to determine if editing should be enabled or not.
+.It Dv EL_GETCFN , Fa "int (*f)(EditLine *, char *c)"
+Define the character reading function as
+.Fa f ,

+.Sh NAME
+.Nm editrc
+.Nd configuration file for editline library
+.Sh SYNOPSIS
+.Nm
+.Sh DESCRIPTION
+The
+.Nm
+file defines various settings to be used by the
+.Xr editline 3
+library.
+.Pp
+The format of each line is:
+.Dl [prog:]command [arg [...]]
+.Pp
+.Ar command
+is one of the
+.Xr editline 3
+builtin commands.
+Refer to
+.Sx BUILTIN COMMANDS
+for more information.
+.Pp
+.Ar prog
+is the program name string that a program defines when it calls
+.Xr el_init 3
+to set up
+.Xr editline 3 ,
+which is usually
+.Va argv[0] .
+.Ar command
+will be executed for any program which matches
+.Ar prog .
+.Pp
+.Ar prog
+may also be a
+.Xr regex 3
+style
+regular expression, in which case
+.Ar command
+will be executed for any program that matches the regular expression.
+.Pp
+If
+.Ar prog
+is absent,
+.Ar command
+is executed for all programs.
+.Sh BUILTIN COMMANDS
+The
+.Nm editline
+library has some builtin commands, which affect the way
+that the line editing and history functions operate.
+These are based on similar named builtins present in the
+.Xr tcsh 1
+shell.
+.Pp
+The following builtin commands are available:
+.Bl -tag -width 4n
+.It Ic bind Xo
+.Op Fl a
+.Op Fl e
+.Op Fl k
+.Op Fl l
+.Op Fl r
+.Op Fl s
+.Op Fl v
+.Op Ar key Op Ar command
+.Xc
+Without options, list all bound keys, and the editor command to which
+each is bound.
+If
+.Ar key
+is supplied, show the bindings for
+.Ar key .
+If
+.Ar key command
+is supplied, bind
+.Ar command
+to
+.Ar key .
+Options include:
+.Bl -tag -width 4n
+.It Fl e
+Bind all keys to the standard GNU Emacs-like bindings.
+.It Fl v
+Bind all keys to the standard
+.Xr vi 1 Ns -like
+bindings.
+.It Fl a
+List or change key bindings in the
+.Xr vi 1
+mode alternate (command mode) key map.
+.It Fl k
+.Ar key
+is interpreted as a symbolic arrow key name, which may be one of
+.Sq up ,
+.Sq down ,
+.Sq left
+or
+.Sq right .
+.It Fl l
+List all editor commands and a short description of each.
+.It Fl r
+Remove a key's binding.
+.It Fl s
+.Ar command
+is taken as a literal string and treated as terminal input when
+.Ar key
+is typed.
+Bound keys in
+.Ar command
+are themselves reinterpreted, and this continues for ten levels of
+interpretation.
+.El
+.Pp
+.Ar command
+may be one of the commands documented in
+.Sx "EDITOR COMMANDS"
+below, or another key.
+.Pp
+.Ar key
+and
+.Ar command
+can contain control characters of the form
+.Sm off
+.Sq ^character
+.Sm on
+.Po
+e.g.
+.Sq ^A
+.Pc ,
+and the following backslashed escape sequences:
+.Pp
+.Bl -tag -compact -offset indent -width 4n

+Newline
+.It Ic \er
+Carriage return
+.It Ic \et
+Horizontal tab
+.It Ic \ev
+Vertical tab
+.Sm off
+.It Sy \ennn
+.Sm on
+The ASCII character corresponding to the octal number
+.Ar nnn .
+.El
+.Pp
+.Sq \e
+nullifies the special meaning of the following character,
+if it has any, notably
+.Sq \e
+and
+.Sq ^ .
+.It Ic echotc Xo
+.Op Fl sv
+.Ar arg
+.Ar ...
+.Xc
+Exercise terminal capabilities given in
+.Ar arg Ar ... .
+If
+.Ar arg
+is
+.Sq baud ,
+.Sq cols ,
+.Sq lines ,
+.Sq rows ,
+.Sq meta or
+.Sq tabs ,
+the value of that capability is printed, with
+.Dq yes
+or
+.Dq no
+indicating that the terminal does or does not have that capability.
+.Pp
+.Fl s
+returns an empty string for non-existent capabilities, rather than
+causing an error.
+.Fl v
+causes messages to be verbose.
+.It Ic edit Op on | off
+Enable or disable the
+.Nm editline
+functionality in a program.
+.It Ic history Ar list | Ar size n | Ar unique n
+The
+.Ar list
+command lists all entries in the history.
+The
+.Ar size
+command sets the history size to
+.Dv n
+entries.
+The
+.Ar unique
+command controls if history should keep duplicate entries.
+If
+.Dv n
+is non zero, only keep unique history entries.
+If
+.Dv n
+is zero, then keep all entries (the default).
+.It Ic telltc
+List the values of all the terminal capabilities (see
+.Xr termcap 5 ) .
+.It Ic settc Ar cap Ar val
+Set the terminal capability
+.Ar cap
+to
+.Ar val ,

+.Op Fl q
+.Op Fl x
+.Op Ar +mode
+.Op Ar -mode
+.Op Ar mode
+.Op Ar char=c
+.Xc
+Control which tty modes that
+.Nm
+won't allow the user to change.
+.Fl d ,
+.Fl q
+or
+.Fl x
+tells
+.Ic setty
+to act on the
+.Sq edit ,
+.Sq quote
+or
+.Sq execute
+set of tty modes respectively; defaulting to
+.Fl x .
+.Pp
+Without other arguments,
+.Ic setty
+lists the modes in the chosen set which are fixed on
+.Po
+.Sq +mode
+.Pc
+or off
+.Po
+.Sq -mode
+.Pc .
+.Fl a
+lists all tty modes in the chosen set regardless of the setting.
+With
+.Ar +mode ,
+.Ar -mode
+or
+.Ar mode ,
+fixes
+.Ar mode
+on or off or removes control of
+.Ar mode
+in the chosen set.
+.Pp
+.Ic Setty
+can also be used to set tty characters to particular values using
+.Ar char=value .
+If
+.Ar value
+is empty
+then the character is set to
+.Dv _POSIX_VDISABLE .

+Note about Version Numbers
+
+ The three numbers stand for CURRENT:REVISION:AGE, or C:R:A for short. The
+ libtool script typically tacks these three numbers onto the end of the name of
+ the .so file it creates. The formula for calculating the file numbers on Linux
+ and Solaris is (C - A).(A).(R), so the example given here would create the
+ file libgrump.so.3.2.1. Other operating systems might use a different library
+ file name convention; libtool takes care of the details.
+
+ As you release new versions of your library, you will update the library's
+ C:R:A. Although the rules for changing these version numbers can quickly
+ become confusing, a few simple tips should help keep you on track. The libtool
+ documentation goes into greater depth.
+
+ In essence, every time you make a change to the library and release it, the
+ C:R:A should change. A new library should start with 0:0:0. Each time you
+ change the public interface (i.e., your installed header files), you should
+ increment the CURRENT number. This is called your interface number. The main
+ use of this interface number is to tag successive revisions of your API.
+
+ The AGE number is how many consecutive versions of the API the current
+ implementation supports. Thus if the CURRENT library API is the sixth
+ published version of the interface and it is also binary compatible with the
+ fourth and fifth versions (i.e., the last two), the C:R:A might be 6:0:2. When
+ you break binary compatibility, you need to set AGE to 0 and of course
+ increment CURRENT.
+
+ The REVISION marks a change in the source code of the library that doesn't
+ affect the interface-for example, a minor bug fix. Anytime you increment
+ CURRENT, you should set REVISION back to 0.
