Question 1

How does strutil compare to the standard strings package in Go?

Accepted Answer

strutil extends the standard strings package with additional utilities like text alignment, boxing, and case conversion, but for basic operations, the standard library is lighter and sufficient. Use strutil if you need its specific features, such as DrawBox or SafeSubstring, to avoid reinventing the wheel.

Question 2

How to generate a slug from a string using strutil?

Accepted Answer

Use the Slugify function to convert a string to a lowercase, hyphenated slug. For example, strutil.Slugify('Hello World!') returns 'hello-world'. You can customize the delimiter with SlugifySpecial for underscores or other characters.

Question 3

Does strutil handle multi-byte or UTF-8 strings correctly?

Accepted Answer

Yes, functions like Len use utf8.RuneCountInString for rune-aware length, and RemoveAccents processes accented characters. However, for full Unicode support like grapheme clusters, you may need to supplement with other libraries such as golang.org/x/text.

Question 4

Is strutil suitable for CLI tool development?

Accepted Answer

Absolutely, strutil is ideal for CLI tools with functions for text alignment, wrapping, and boxing, as shown with DrawBox and WordWrap examples. It helps format output neatly, such as creating padded tables or framed messages in terminal applications.

Question 5

Can I use strutil with web frameworks like Gin or Echo?

Accepted Answer

Yes, strutil is a general-purpose library and can be integrated into any Go project, including web apps. It's useful for tasks like slug generation for URLs or cleaning user input, such as with RemoveAccents or CountWords.

Question 6

How to install and update strutil in a Go project?

Accepted Answer

Install using 'go get github.com/ozgio/strutil'. For updates, run 'go get -u github.com/ozgio/strutil'. Ensure Go 1.10+ is installed, as specified in the README, and manage versions via go.mod for dependency control.
