help with a database in newlisp

Post by tomtoo »

Hi guys,

I need a little help with creating a database with newlisp. I'd like to use "lookup" to search for various things, but I'm not sure how to create the database with all the needed elements. here's the result of what I have now:

Code: Select all

(set 'all-computers '(
  ((atag "444") (person "yyy") (room "") (role nil))))
This does not look right! how can I do something like

Code: Select all

(lookup person all-computers) 
and determine atag or "not entered" for room or role?

I'll probably use this for myself, and use it to populate a real database or spreadsheet.

thanks :-)

Hello,

You may have a look at nldb from here:

https://github.com/cormullion/newlisp-p ... aster/nldb

You may also find discussions here with a Forum search for 'nldb'

At least you can use 'assoc' on your list.

Or use modules for real databases.

Regards
Hans-Peter

The book "A Practical Introduction to Fuzzy Logic using LISP" contains a section that explains the management of csv files (builds a simple CSV library).
The code is written in newLisp.
