golang-github-knetic-govaluate-dev - 3.0.0+git20171022.9aa4983-2 main

Provides support for evaluating arbitrary C-like artithmetic/string
expressions.
.
Sometimes, you can't know ahead-of-time what an expression will look
like, or you want those expressions to be configurable. Perhaps
you've got a set of data running through your application, and you
want to allow your users to specify some validations to run on it
before committing it to a database. Or maybe you've written a
monitoring framework which is capable of gathering a bunch of
metrics, when evaluating a few expressions to see if any metrics
should be alerted upon, but the conditions for alerting are different
for each monitor.
.
A lot of people wind up writing their own half-baked style of
evaluation language that fits their needs, but isn't complete. Or they
wind up baking the expression into the actual executable, even if
they know it's subject to change. These strategies may work, but they
take time to implement, time for users to learn, and induce technical
debt as requirements change. This library is meant to cover all the
normal C-like expressions, so that you don't have to reinvent one of
the oldest wheels on a computer.
