Hi Lutz,
Customized readline macro's can be created for "specific" programs
inside the ~/.inputrc file by use of $if <name>
If newlisp would have defined -> char * rl_readline_name <-
***
This variable is set to a unique name by each application using
Readline. The value allows conditional parsing of the inputrc file
(see Conditional Init Constructs.).
***
People can create readline macro's inside their ~/.inputrc specificly
for newlisp only! So they wont work outside the newlisp shell i.e.
inside bash..
$if newlisp
# Quote the current or previous word
"C-nq": "eb(ef)"
$endif
like this in newlisp.c ->
(checked and works)
#ifdef READLINE
if(isTTY)
{
rl_readline_name = "newlisp";
errnoSave = errno;
if((cmd = readline(prompt())) == NULL) exit(0);
errno = errnoSave; /* reset errno, set by readline() */
if(strlen(cmd) > 0) add_history(cmd);
executeCommandLine(cmd, OUT_CONSOLE, &cmdStream);
free(cmd);
continue;
}
if(IOchannel != stdin || forcePromptMode)
varPrintf(OUT_CONSOLE, prompt());
#endif
And something which is on my wish list for some time,
being a tty user.. that is called name completion..
As with readline yuo can complete yuor typing by pressing (double TAB)
//http://docs.freebsd.org/info/readline/readline.info.Completion_Functions.html
It should not be a lot of code to make "newlisp SYMBOL" completion possible
in newlisp i guess?
What do you think Lutz? Is it an option to build in into the
newlisp-console when reladine is compiled with it?
Norman.
PS: regaring this option, Im investigating if its possible to make this
work with 100% newlisp code...
I can include 'rl_readline_name="newlisp"' in the code. The question is, if there is a way to put a list of all names to complete into .inputrc, so I don't have to burden the code with a completion_matches() function.
Also I could not get your quoting examle to work after compiling with 'rl_readline_name'. What am I supposed to type for "C-nq": "eb(ef)"? Ctrl-NQ will delete the whole line.
the environment default points to /etc/inputrc
you can do a "export INPUTRC=~/.inputrc" if youre using Bash
or leave it empty "export INPUTRC"..
because bash needs to re-read the inputrc.. I just put it inside
/etc/inputrc that easier and works directly..
There could be a trick with a readline-macro to "grab" from a file
and link that to the completion perhpas..ill have a look...
btw...
If you have put the macro inside the inputrc..
start newlisp and press CTRL-n then plain "q" after i.e. typing hello...
it will make it (hello)..
if the rl_readline_name is inside your newlisp code your need to
put inside the inputrc the statement of $if newlisp.....
doing readline completion still could be done in 100% newlisp code
together wth the inputrc file.. im heading towards a solutions.. hold on ;-)
Its not possible to interact from the outside with readline macro's
with the internal buffer of readline. The only Trick is putting all the
symbols inside a directory and then handle it as filenames, but no option..
So also with a readline keyboard macro i cant get there.. There must be
something from inside newlisp that points to a buffer/file.. From that point
on you could execute newlisp-commands to parse that file and append
it to the current cursor position...
Perhpas the completion should not be part of newlisp binary if it
takes too much resources/code.
Im now working with 'read-key to make this working under linux
together with command-event as an alternative..this implies that
readline doesnt work anymore..which is a backdraw...
(on second thought... too much work, need to rewrite actualy a complete
line handler in newlisp...)
when using BASH there is a configurable way to use completion!
see the manpage of bash... This could be done 100% in newlisp scripting
actualy.. but im not sure yet it is copied into newlisp command shell
when running ontop of bash...
Its done!
Took very little code, because I could use the existing primitive[] array which has all the names of built-in primitives.

look for 9.9.95 on Monday
ps: when nothing is entered, or only the opening parenthesis and hitting Tab and yes, it will show all 341 built-in functions, nicely formatted in a multicolumn list
...marvelous solution!!!
Thanks!
Thanks! This is really neat! :-)
