even.git, branch masterA very basic c binary to check if an input number is even.
https://git.zachir.xyz/even.git/atom?h=master2024-03-11T07:00:31ZAdd error handling for non-numbers passed2024-03-11T07:00:31Zzachirzachir@librem.one2024-03-11T07:00:31Zurn:sha1:3d95ee49b4e45c11d0a9d6368ea3ec6808006a35
Non-numbers that are passed will return -1, and print an error message.
This includes decimal places, as only integers can be even or odd.
Prints help msg when no args2024-03-11T06:59:34Zzachirzachir@librem.one2024-03-11T06:59:34Zurn:sha1:45933ed41766da5e08b59f970ff58df63eb18c8b
When no args are provided, even will now print the help message and
return -1.
Fixes logic error with quiet2024-03-11T06:57:53Zzachirzachir@librem.one2024-03-11T06:57:53Zurn:sha1:934a7be0be6764c8b47aedbf6aad22654d3bd3f2
Before, quiet worked in reverse, i.e. text was only displayed when -q
was passed. Also, even now will not return 1 with an odd number when
quiet is not passed.
Add install/uninstall to Makefile2024-03-11T06:42:53Zzachirzachir@librem.one2024-03-11T06:42:53Zurn:sha1:ccb5c84449f930aa66d8ee9d47f7a5d806ce5df5Replace build system with zig2024-03-11T06:34:22Zzachirzachir@librem.one2024-03-11T06:34:22Zurn:sha1:2b135d87f5c1f1f307984f5fd78e151f5ee99dae
Zig is actually handling the building and such, now the Makefile is
here just as a wrapper for it.
Optimize for size, and redo Makefile2024-03-07T05:32:28Zzachirzachir@librem.one2024-03-07T05:32:28Zurn:sha1:42b5d719a0207a56b482a4e0298d72b628b93fa0
Optimizing for size for the current comparison. Also, I don't know of a
generic way to do ${OBJ}: ${SRC} as a Makefile target, so I made that
part not generic.
Use strtol instead of checking each digit2024-03-07T05:31:51Zzachirzachir@librem.one2024-03-07T05:31:51Zurn:sha1:a94711362f844d5de6b498d05f12611312e22e0d
This makes it both faster and smaller.
Reorganize the help message2024-03-07T05:30:08Zzachirzachir@librem.one2024-03-07T05:30:08Zurn:sha1:ea86302d44a0370264959970eb624035aeb4cef4
Changed around stuff in the help message to make it more consistent
with zeven.
even: Fix help message2024-02-15T05:57:43Zzachirzachir@librem.one2024-02-15T05:57:43Zurn:sha1:9c60d421fd95a33350ac9c68512e6b1d2edd9f27
The help message was missing some information, that has now been added.
even: Add bin to check if number is even2024-02-15T05:54:52Zzachirzachir@librem.one2024-02-15T05:54:52Zurn:sha1:0689d6bbbb0e6ecc3934d8e4a2e9b0fc66a0b29f
even is a basic binary to check if the provided number is even.
