Inspired by filesize.js.
$ sudo luarocks install lua-filesize
This library installs a single module called filesize
.
It is represented with a function of the same name.
Principally it takes an integer (filesize) and returns
a human readable string describing the file size.
filesize()
accepts an optional second argument options
of type table
, so you can customize the output.
-
base
(number) Number base, default is 2 -
bits
(boolean) Enables bit sizes, default is false -
exponent
(number) Specifies the SI suffix via exponent, e.g. 2 is MB for bytes, default is -1 -
output
(string) Output of function (array, exponent, object, or string), default is string -
round
(number) Decimal place, default is 2 -
spacer
(string) Character between the result and suffix, default is " " -
suffixes
(table) Dictionary of SI suffixes to replace for localization, defaults to english if no match is found -
unix
(boolean) Enables unix style human readable output, e.g.ls -lh
, default is false

"259.1 KB"

{
value = 259.1,
suffix = "KB",
}
> filesize(1, {suffixes = {B = "Б"}})
"1 Б"
> filesize(1024)
"1 KB"
> filesize(1024, {exponent = 0})
"1024 B"
> filesize(1024, {output = "exponent"})
