util.human.io: Add parse_duration() method to parse a duration string
Similar logic occurs throughout various modules in the codebase. We might even
want a module:get_option_duration()??
local units = require "util.human.units";
describe("util.human.units", function ()
describe("format", function ()
it("formats numbers with SI units", function ()
assert.equal("1 km", units.format(1000, "m"));
assert.equal("1 GJ", units.format(1000000000, "J"));
assert.equal("1 ms", units.format(1/1000, "s"));
assert.equal("10 ms", units.format(10/1000, "s"));
assert.equal("1 ns", units.format(1/1000000000, "s"));
assert.equal("1 KiB", units.format(1024, "B", 'b'));
assert.equal("1 MiB", units.format(1024*1024, "B", 'b'));
end);
end);
end);
