enabling readline support

[tom]

Hi guys,



I have a 64 bit amd processor, and I build newlisp with "make linux64LP64."

"make linux64" does not work...



I used to use "make linux_readline" but I don't think I can do that now that I'm 64 bit.  



What, oh what ever shall I do?

Allthough your CPU is 64Bit with 99% probability it still is a system with mainly 32-but applications libraries.



Try:



make linux_readline



Then do:



make test



To do a whole test suite



If that fails, try:



make -f makefile_linux64ILP32



but edit the file first to uncomment the readline options, or use:



make linux_readline



but in makefile_linux_readline put a: -m32 switch in the CC compile line. That forces 32-bit on 64-bit systems.



Ps: you can use all make files directly doing  a: makefile_xxxxx. Look into the makefiles and experiment, its no rocket science ;-)

ok

:-)



I actually do have 64 bit libraries, though.  I'm using 64 bit Arch Linux.

Ok, if you have 64-bit libraries, you could use:



make -f makefile_linux64LP64



just make sure to add -DREADLINE to the CFLAGS line and -lreadline and perhaps one of -ltermcap and -lncurses to the CC line



64-Bit newLISP will be about 30% faster, but also use almost double the memory, trying to give you more than 4G of RAM. You may run into trouble if you have to import MySQL, SQLite etc. All the modules coming with newLISP are 32-bit interfaces, and so are most of these apps on 64-bit CPUs.

bingo.  thanks.

Or you can get 'rlwrap' from here:



http://utopia.knoware.nl/~hlub/uck/software/">http://utopia.knoware.nl/~hlub/uck/software/



Start your newlisp prompt as follows:

rlwrap newlisp

In your KSH/CSH/BASH profile add an alias which aliases newlisp always:

Code Select Expand


alias newlisp='rlwrap newlisp'


The nice thing about this wrapper is, that it also points to opening and closing paranthesis while you are typing. Besides this, it also will remember all the lines you have typed in previous sessions with newLisp!

rlwrap looks cool, but it doesn't seem to work correctly with readline-enabled newlisp.



I tried it with a newlisp minus readline and the parens flashed at me; but with newlisp plus readline they didn't.



hmm.

[pjot]

Well, for you it's easier compiling newLisp anyway.... no fuzz with editing Makefiles. In the future just run 'make' to compile newLisp, and let 'rlwrap' do all the work. It will create a '.newlisp_history' in your homedir with the complete history of commands entered in all your interactive newLisp sessions. Also the flashing of the parens is an advantage (at least for me it is).
