Question 1

How to format file sizes in Go using go-humanize?

Accepted Answer

Use the humanize.Bytes function with a byte count, like humanize.Bytes(82854982) to get '83 MB'. It supports both metric (MB) and binary (MiB) units as per the README examples.

Question 2

Does go-humanize support non-English languages for pluralization?

Accepted Answer

No, it only supports English through the humanize/english subpackage. For other languages, you'd need to implement custom logic or use another library, as highlighted in the English utilities section.

Question 3

go-humanize vs standard fmt package for number formatting?

Accepted Answer

go-humanize adds human-friendly touches like commas in numbers (humanize.Comma) and relative time phrases, while fmt is more general-purpose. Use go-humanize for user-facing readability, but fmt for precise control or performance-critical code.

Question 4

How to install go-humanize in a Go project?

Accepted Answer

Run 'go get github.com/dustin/go-humanize' and import it in your code. The README provides clear setup instructions, and it's dependency-free, making integration straightforward.

Question 5

What are the performance implications of using go-humanize?

Accepted Answer

It adds string processing overhead for formatting, which might be negligible for most apps but could impact high-frequency operations. Since it's lightweight, the cost is generally low, but test in performance-sensitive contexts.

Question 6

Can I customize the output formats in go-humanize, like changing time phrases?

Accepted Answer

No, the library uses fixed formats without customization options. For example, humanize.Time always outputs relative phrases like '3 days ago', and there's no API to alter this without forking the code.
