string?(3scm)

✨ NAME ✨

okay so bestie, this is string?(3scm) — the manual page for string? from the Scheme Programmer's Manual. Its whole vibe: test if an object is a string. no cap 💅

📚 LIBRARY 📚

import these, bestie:

(import (rnrs))                     ;R6RS
(import (rnrs base))                ;R6RS
(import (scheme r5rs))              ;R7RS
(import (scheme base))              ;R7RS

🫶 SYNOPSIS 🫶

the call looks like this:

(string? obj)

💅 DESCRIPTION 💅

Returns #t if obj is a string, otherwise returns #f. literally that simple ✨

🎀 RETURN VALUES 🎀

Returns a single boolean object as per the description. one boolean, that’s the whole return situation 🫶

🧚 EXAMPLES 🧚

vibe check on the examples:

(string? "123")        => #t
(string? '#(1 2 3))    => #f
(string? '(1 2 3))     => #f

💀 ERRORS 💀

This procedure can raise exceptions with the following condition types:

• &assertion (R6RS) — the wrong number of arguments was passed.
• R7RS — the assertions described above are errors. Implementations may signal an error, extend the procedure's domain of definition to include such arguments, or fail catastrophically.

bestie, “fail catastrophically” is right there in the original wording, so yeah — that’s a real caveat, not me being dramatic 😭
