validators

C validators. This project is more for learning C language and practice in C. The main idea is rewriting VyOS validators to C, as some of them slower that could be. https://github.com/vyos/vyos-1x/tree/current/src/validators

It is a good idea to check them locally and practice in C.

Path for sources src/validators-c/

Path for binaries src/validators/

build

Build binaries

$ make all

# or make validators
$ make validators

Check binaries:

$ ls src/validators/
numeric-range-c

$ ./src/validators/numeric-range-c -r 10-50 20 && echo "True" || echo "False"
True

$ ./src/validators/numeric-range-c -r 10-50 2220 && echo "True" || echo "False"
The value 2220 is out of the range 10-50
False

tests

C validators faster even then OCAML validators. Original numeric vs C numeric-range-c:
