Introduction
|
|
============
|
|
|
|
This is the Gnu Readline library, version 4.3.
|
|
|
|
The Readline library provides a set of functions for use by applications
|
|
that allow users to edit command lines as they are typed in. Both
|
|
Emacs and vi editing modes are available. The Readline library includes
|
|
additional functions to maintain a list of previously-entered command
|
|
lines, to recall and perhaps reedit those lines, and perform csh-like
|
|
history expansion on previous commands.
|
|
|
|
The history facilites are also placed into a separate library, the
|
|
History library, as part of the build process. The History library
|
|
may be used without Readline in applications which desire its
|
|
capabilities.
|
|
|
|
The Readline library is free software, distributed under the terms of
|
|
the [GNU] General Public License, version 2. For more information, see
|
|
the file COPYING.
|
|
|
|
To build the library, try typing `./configure', then `make'. The
|
|
configuration process is automated, so no further intervention should
|
|
be necessary. Readline builds with `gcc' by default if it is
|
|
available. If you want to use `cc' instead, type
|
|
|
|
CC=cc ./configure
|
|
|
|
if you are using a Bourne-style shell. If you are not, the following
|
|
may work:
|
|
|
|
env CC=cc ./configure
|
|
|
|
Read the file INSTALL in this directory for more information about how
|
|
to customize and control the build process.
|
|
|
|
The file rlconf.h contains C preprocessor defines that enable and disable
|
|
certain Readline features.
|
|
|
|
The special make target `everything' will build the static and shared
|
|
libraries (if the target platform supports them) and the examples.
|
|
|
|
Examples
|
|
========
|
|
|
|
There are several example programs that use Readline features in the
|
|
examples directory. The `rl' program is of particular interest. It
|
|
is a command-line interface to Readline, suitable for use in shell
|
|
scripts in place of `read'.
|
|
|
|
Shared Libraries
|
|
================
|
|
|
|
There is skeletal support for building shared versions of the
|
|
Readline and History libraries. The configure script creates
|
|
a Makefile in the `shlib' subdirectory, and typing `make shared'
|
|
will cause shared versions of the Readline and History libraries
|
|
to be built on supported platforms.
|
|
|
|
If `configure' is given the `--enable-shared' option, it will attempt
|
|
to build the shared libraries by default on supported platforms.
|
|
|
|
Configure calls the script support/shobj-conf to test whether or
|
|
not shared library creation is supported and to generate the values
|
|
of variables that are substituted into shlib/Makefile. If you
|
|
try to build shared libraries on an unsupported platform, `make'
|
|
will display a message asking you to update support/shobj-conf for
|
|
your platform.
|
|
|
|
If you need to update support/shobj-conf, you will need to create
|
|
a `stanza' for your operating system and compiler. The script uses
|
|
the value of host_os and ${CC} as determined by configure. For
|
|
instance, FreeBSD 4.2 with any version of gcc is identified as
|
|
`freebsd4.2-gcc*'.
|
|
|
|
In the stanza for your operating system-compiler pair, you will need to
|
|
define several variables. They are:
|
|
|
|
SHOBJ_CC The C compiler used to compile source files into shareable
|
|
object files. This is normally set to the value of ${CC}
|
|
by configure, and should not need to be changed.
|
|
|
|
SHOBJ_CFLAGS Flags to pass to the C compiler ($SHOBJ_CC) to create
|
|
position-independent code. If you are using gcc, this
|
|
should probably be set to `-fpic'.
|
|
|
|
SHOBJ_LD The link editor to be used to create the shared library from
|
|
the object files created by $SHOBJ_CC. If you are using
|
|
gcc, a value of `gcc' will probably work.
|
|
|
|
SHOBJ_LDFLAGS Flags to pass to SHOBJ_LD to enable shared object creation.
|
|
If you are using gcc, `-shared' may be all that is necessary.
|
|
These should be the flags needed for generic shared object
|
|
creation.
|
|
|
|
SHLIB_XLDFLAGS Additional flags to pass to SHOBJ_LD for shared library
|
|
creation. Many systems use the -R option to the link
|
|
editor to embed a path within the library for run-time
|
|
library searches. A reasonable value for such systems would
|
|
be `-R$(libdir)'.
|
|
|
|
SHLIB_LIBS Any additional libraries that shared libraries should be
|
|
linked against when they are created.
|
|
|
|
SHLIB_LIBSUFF The suffix to add to `libreadline' and `libhistory' when
|
|
generating the filename of the shared library. Many systems
|
|
use `so'; HP-UX uses `sl'.
|
|
|
|
SHLIB_LIBVERSION The string to append to the filename to indicate the version
|
|
of the shared library. It should begin with $(SHLIB_LIBSUFF),
|
|
and possibly include version information that allows the
|
|
run-time loader to load the version of the shared library
|
|
appropriate for a particular program. Systems using shared
|
|
libraries similar to SunOS 4.x use major and minor library
|
|
version numbers; for those systems a value of
|
|
`$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate.
|
|
Systems based on System V Release 4 don't use minor version
|
|
numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems.
|
|
Other Unix versions use different schemes.
|
|
|
|
SHLIB_STATUS Set this to `supported' when you have defined the other
|
|
necessary variables. Make uses this to determine whether
|
|
or not shared library creation should be attempted.
|
|
|
|
You should look at the existing stanzas in support/shobj-conf for ideas.
|
|
|
|
Once you have updated support/shobj-conf, re-run configure and type
|
|
`make shared'. The shared libraries will be created in the shlib
|
|
subdirectory.
|
|
|
|
If shared libraries are created, `make install' will install them.
|
|
You may install only the shared libraries by running `make
|
|
install-shared' from the top-level build directory. Running `make
|
|
install' in the shlib subdirectory will also work. If you don't want
|
|
to install any created shared libraries, run `make install-static'.
|
|
|
|
Documentation
|
|
=============
|
|
|
|
The documentation for the Readline and History libraries appears in
|
|
the `doc' subdirectory. There are three texinfo files and a
|
|
Unix-style manual page describing the facilities available in the
|
|
Readline library. The texinfo files include both user and
|
|
programmer's manuals. HTML versions of the manuals appear in the
|
|
`doc' subdirectory as well.
|
|
|
|
Reporting Bugs
|
|
==============
|
|
|
|
Bug reports for Readline should be sent to:
|
|
|
|
bug-readline@gnu.org
|
|
|
|
When reporting a bug, please include the following information:
|
|
|
|
* the version number and release status of Readline (e.g., 4.2-release)
|
|
* the machine and OS that it is running on
|
|
* a list of the compilation flags or the contents of `config.h', if
|
|
appropriate
|
|
* a description of the bug
|
|
* a recipe for recreating the bug reliably
|
|
* a fix for the bug if you have one!
|
|
|
|
If you would like to contact the Readline maintainer directly, send mail
|
|
to bash-maintainers@gnu.org.
|
|
|
|
Since Readline is developed along with bash, the bug-bash@gnu.org mailing
|
|
list (mirrored to the Usenet newsgroup gnu.bash.bug) often contains
|
|
Readline bug reports and fixes.
