Humanize.jl

Humanize numbers, including

• data sizes (3e6 -> 3.0 MB or 2.9 MiB).
• Date/datetime differences (Date(2014,2,3) - Date(2013,3,7) -> 1 year, 1 month)
• Digit separator (12345678 -> 12,345,678)
• Prettification of numbers (1988.12345678 -> 1.988⋅10³)

This package is MIT licensed, and is based on jmoiron's humanize Python library.

Installation: Pkg.add("Humanize")

Documentation

All functions are also documented using Julia's in-built help system, e.g. ?datasize.

Data sizes

datasize(value::Number; style=:dec, format="%.1f")

Style can be :dec (base 10^3), :bin (base 2^10), :gnu (base 2^10, like ls -hs).

julia> datasize(3000000)
"3.0 MB"
julia> datasize(3000000, style=:bin, format="%.3f")
"2.861 MiB"
julia> datasize(3000000, style=:gnu, format="%.3f")
"2.861M"

Date/datetime differences

timedelta(secs::Integer)
timedelta{T<:Integer}(years::T,months::T,days::T,hours::T,mins::T,secs::T)
timedelta(dt_diff::Dates.Millisecond)
timedelta(d_diff::Dates.Day)

Turns a date/datetime difference into a abbreviated human-friendly form.

julia> timedelta(70)
"a minute"
julia> timedelta(0,0,0,23,50,50)
"23 hours"
julia> timedelta(DateTime(2014,2,3,12,11,10) -
                    DateTime(2013,3,7,13,1,20))
"11 months"
julia> timedelta(Date(2014,3,7) - Date(2013,2,4))
"1 year, 1 month"

Digit separator

julia> digitsep(12345678)
"12,345,678"
julia> digitsep(12345678, sep = "'")
"12'345'678"
julia> digitsep(12345678, sep = "-", k = 4)
"1234-5678"

Nice numbers

julia> nicenumber("ρ ≃ 00.04 ± 2e-3")
"ρ ≃ 0.04 ± 0.002"
julia> nicenumber("-100000000")
"-1⋅10⁸"
julia> nicenumber(-1e20)
"-1⋅10²⁰"
