Subject: [PATCH 0/1] zsh/random module
Date: Sun, 24 Mar 2024 09:11:37 -0500 [thread overview]
Message-ID: <57374b5f-77b9-4dee-aaba-5c4bdeb1b281@zentaur.org> (raw)
This is a resurrection of a module to provide an interface into the
kernel random pool for the shell.
It provides a ro parameter SRANDOM (32-bit random integer)
It provides 2 math functions zrand_float() and zrand_int
zrand_int takes 0-3 arguments, an exclusive upper bound, a lower bound,
a flag to make the upper bound inclusive. It is equivalent to SRANDOM
with no arguments.
zrand_float takes no arguments and returns a floating point number
between 0 and 1, inclusive.
I am still working on the test harness. I'm thinking about using a C
program for analysis of shell output, but no current test harness does
anything like that. (long double would really be helpful for larger
bounds, 1-20 works, 1-100 causes overflows)
This version has no builtins. Though I still think some could be
useful, I have to admit that what I have in mind for them *can* be
accomplished in shell by someone with moderate experience, if less
efficiently.
