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

dnl extern int read_history ();
