Introduction ============ This is the Gnu Readline library, version 2.2 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 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 defines that enable and disable certain Readline features. 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. Typing `make shared' will cause shared versions of the Readline and History libraries to be built on SunOS 4.1.x. For versions of Unix other than SunOS, you will have to make some changes to Makefile.in. The relevant variables are: PICFLAG Options to give to the compiler to produce position-independent code. The value `-fpic' works for most versions of gcc. SHLIB_OPTS Options to give to the linker to produce a shared library. The value `-assert pure-text -ldl' works on SunOS 4.1.x. The value `-Bshareable' works for some versions of GNU ld. MAJOR The major version number of the shared library. You should not need to change this. MINOR The minor version number of the shared library. Some systems, such as SVR4 and its descendents (e.g., Solaris, Unixware), do not use minor version numbers. For those systems, this variable should be left unset. LD The linker. The value of `ld' is correct for SunOS 4.1.x. You may need to change it to `gcc'; make sure to change SHLIB_OPTS if you do so. Once you have edited Makefile.in, type `make Makefile' to rebuild the Makefile, then `make shared' to build the shared libraries. Documentation ============= The documentation for the Readline and History libraries appears in the `doc' subdirectory. There are two texinfo files and a Unix-style manual page describing the programming facilities available in the Readline library. The texinfo files include both user and programmer's manuals. 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., 2.2-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.
