2. Introduction
Several constants libraries are available for the 42s, and some of them are quite good. Unfortunately nobody is going to make a constants library with just the constants I use. ;)
This Emacs org-file contains a bit of lisp code to write a 42s CONST program with the constants you want.
The constants I use are taken from the NIST 2018 constants DB. As a reference I have included the unused constants from the NIST list.
The flow to create your custom CONST program:
- Evaluate the "Generic menu generator" babel block in hp42s-meta.org. This will define the function
MJR-generate-42-menu-code - Put the constants you want into the table in the Constants Used section below (see: Customizing the Constants Table)
- Optional: Customize the generator code in the Code section below. (see: Customizing the Gen Code)
- Evaluate the babel block in the Code section below.
- Load the program on your calculator
2.1. Customizing the Constants Table
The "Menu" column describes the menu keys that will be assigned to the constant. Colons are used to define a menu hierarchy. For example "top:mid:con1"
means we have a top level menu "top" containing a menu "mid" containing a constant "con1". Another entry like "top:con2" would add a constant named
"con2"to the "top" menu – yes menus can contain a mix of constants and menus.
The menu structure can be as deep as you like. The one I use has a top level menu consisting of NIST constant category labels. Each of these menus, except
for "atom", directly contain constants – so most constants are two key presses away. The exception is the atom menu which contains deeper menus – thus
making atomic constants three key presses away.
Note the code generator uses two digit local labels in the generated code, and thus you can run out of labels if you have too many constants. Each menu page and each constant consumes one label.
The "Desc" column is the source for the description printed by the CONS program. Make sure it is 22 chars or less. Note the description print can be
suppressed (see: Customizing the Gen Code)
The "Unit" column is the source for the second line printed by the CONS program. Note I use an odd syntax for the units – everything in front of the "/"
is on the top of the fraction and everything after the "/" is on the bottom. While incorrect syntax for an algebraic expression, it is handy and saves some
space. Note the units print can be suppressed (see: Customizing the Gen Code)
2.2. Customizing the Gen Code
The generator code can be customized in a few ways:
print-desccan be set toNILto suppress printing the descriptionprint-unitcan be set toNILto suppress printing the unit- The
'exitargument toMJR-generate-42-menu-codecan be set to'stayif you prefer the menu to remain after a constant is recalled - The
'upargument toMJR-generate-42-menu-codecan be set to'exitif you prefer the[EXIT]key to entirely exit the application instead of going up one menu level.
