SPVM::Format(3)

💖 Name 💖

okay bestie, welcome to SPVM::Format from the User Contributed Perl Documentation corner — it's Format Utilities, and it's literally the format-utility main character for the sprintf method 💅✨

✨ Usage ✨

so the vibe is: you use Format;, then you call Format->sprintf(...) and get your little formatted string back. the comments are the receipts for what each one returns 🎀🔥

use Format;

# Foo 123 abc 1.115 Bar
my $result = Format->sprintf("Foo %d %s %.3f Bar", [(object)123, "abc", [(object)1.115]);

# %d - "123"
my $result = Format->sprintf("%d", [(object)123]);

# %5d - "  123"
my $result = Format->sprintf("%5d", [(object)123]);

# %05d - "00123"
my $result = Format->sprintf("%05d", [(object)123]);

# %+d - "+123"
my $result = Format->sprintf("%+d", [(object)123]);

# %-5d - "123  "
my $result = Format->sprintf("%-5d", [(object)123]);

# %d - "x"
my $result = Format->sprintf("%c", [(object)'x']);

# %c - "あ"
my $result = Format->sprintf("%c", [(object)Fn->ord("あ")]);

# %s - "ABC"
my $result = Format->sprintf("%s", [(object)"ABC"]);

# %.2s - "AB"
my $result = Format->sprintf("%.2s", [(object)"ABC"]);

# %u - "4294967295"
my $result = Format->sprintf("%u", [(object)-1]);

# %f - "3.141500"
my $result = Format->sprintf("%f", [(object)3.1415]);

# %.2f - "3.14"
my $result = Format->sprintf("%.2f", [(object)3.1415]);

# %g - "3.14"
my $result = Format->sprintf("%g", [(object)3.14]);

# %x - "ff"
my $result = Format->sprintf("%x", [(object)255]);

# %x - "ffffffff"
my $result = Format->sprintf("%x", [(object)-1]);

# %p - "0x8000000000000000"
my $result = Format->sprintf("%p", [(object)$object]);

🦋 Description 🦋

Format is, like, a whole little set of formatting utilities for the sprintf method 🫶 no cap, that's the whole assignment.

---

👑 Class Methods 👑

💅 sprintf 💅

static method sprintf : string ($format : string, $args : object[);

It creates a formatted string from $format and $args ✨ — yes, that's the method signature, brackets and all, keep it exactly like that bestie 🎀

🔥 Specifiers 🔥

this is the specifier zone, and it's giving very important formatting energy 🌈

🌈 Specifier Options 🌈

Specifier options can be written between % and the character of specifier such as d, f 💅 so yeah, they go in that little gap between the % and the specifier character — iykyk.
