makojsmako-utils
Internal utilities for mako and plugins.
API
These utilities are used by mako core and plugins internally, but they may be useful to other plugin developers.
relative(to)
Takes the given to absolute path and gives the relative path from pwd.
NOTE: pwd is cached from startup, so this assumes that cwd never changes.
size(input, [raw])
Takes the given input (string/buffer) and returns the actual size in a
human-friendly format.
The raw argument can be passed to return the size in a raw Number reflecting
the number of bytes.
sizeDiff(a, b)
Takes the given numbers for a and b, computes the delta from a -> b and
returns a human-friendly string showing the change.
For example:
console.log(sizeDiff(1000, 1500))
// 1 kB → 1.5 kB (+50%)
console.log(sizeDiff(1000, 250))
// 1 kB → 250 B (-75%)timer()
Used for timing code with process.hrtime(). A function is returned that will
return the time elapsed since the timer was created. (in a human-friendly
format)
let timer = utils.timer()
// do stuff...
console.log('finished doing stuff (took %s)', timer())The returned function has an optional raw argument. When set to true, it
will instead return the time elapsed in the raw hrtime array format.
