# SYNOPSIS
|
||
|
|
#
|
||
|
|
# AX_LIB_READLINE
|
||
|
|
#
|
||
|
|
# DESCRIPTION
|
||
|
|
#
|
||
|
|
# Searches for a readline compatible library. If found, defines
|
||
|
|
# `HAVE_LIBREADLINE'. If the found library has the `add_history' function,
|
||
|
|
# sets also `HAVE_READLINE_HISTORY'. Also checks for the locations of the
|
||
|
|
# necessary include files and sets `HAVE_READLINE_H' or
|
||
|
|
# `HAVE_READLINE_READLINE_H' and `HAVE_READLINE_HISTORY_H' or
|
||
|
|
# 'HAVE_HISTORY_H' if the corresponding include files exists.
|
||
|
|
#
|
||
|
|
# The libraries that may be readline compatible are `libedit',
|
||
|
|
# `libeditline' and `libreadline'. Sometimes we need to link a termcap
|
||
|
|
# library for readline to work, this macro tests these cases too by trying
|
||
|
|
# to link with `libtermcap', `libcurses' or `libncurses' before giving up.
|
||
|
|
#
|
||
|
|
# Here is an example of how to use the information provided by this macro
|
||
|
|
# to perform the necessary includes or declarations in a C file:
|
||
|
|
#
|
||
|
|
# #ifdef HAVE_LIBREADLINE
|
||
|
|
# # if defined(HAVE_READLINE_READLINE_H)
|
||
|
|
# # include <readline/readline.h>
|
||
|
|
# # elif defined(HAVE_READLINE_H)
|
||
|
|
# # include <readline.h>
|
||
|
|
# # else /* !defined(HAVE_READLINE_H) */
|
||
|
|
# extern char *readline ();
|
||
|
|
# # endif /* !defined(HAVE_READLINE_H) */
|
||
|
|
# char *cmdline = NULL;
|
||
|
|
# #else /* !defined(HAVE_READLINE_READLINE_H) */
|
||
|
|
# /* no readline */
|
||
|
|
# #endif /* HAVE_LIBREADLINE */
|
||
|
|
#
|
||
|
|
# #ifdef HAVE_READLINE_HISTORY
|
||
|
|
# # if defined(HAVE_READLINE_HISTORY_H)
|
||
|
|
# # include <readline/history.h>
|
||
|
|
# # elif defined(HAVE_HISTORY_H)
|
||
|
|
# # include <history.h>
|
||
|
|
# # else /* !defined(HAVE_HISTORY_H) */
|
||
|
|
# extern void add_history ();
|
||
|
|
# extern int write_history ();
|
||
|
|
# extern int read_history ();
|
||
|
|
# # endif /* defined(HAVE_READLINE_HISTORY_H) */
|
||
|
|
# /* no history */
|
||
|
|
# #endif /* HAVE_READLINE_HISTORY */
