💖 Plucene::Analysis::LowerCaseFilter 💖

okay bestie, welcome to the Plucene::Analysis::LowerCaseFilter page — it's part of the User Contributed Perl Documentation, so you know it's the community-coded, hand-me-down, beloved-by-the-people kind of documentation. it lives in the Plucene::Analysis family and its whole job is chef's kiss simple. let's get into it ✨

---

✨ NAME ✨

Plucene::Analysis::LowerCaseFilter — this one normalises token text to lower case. that's it. that's the whole personality. and honestly? iconic. 💅

---

🌸 SYNOPSIS 🌸

# usa Plucene::Analysis::TokenFilter

my $next = $l_case_filter->next;

so you grab the next token like that, and $next is where the magic lands. no cap, that's the entire setup. 🦋

---

🎀 DESCRIPTION 🎀

this normalises token text to lower case. lowercase vibes only, fr fr. everything that comes through gets its volume turned down to lowercase. 🔥

---

👑 METHODS 👑

💫 next 💫

my $next = $l_case_filter->next;

this will return the next token in the stream, or undef at the end of string. so when you hit the end, you get undef — not an error, not a vibe check fail, just the gentle signal that the stream said "that's all bestie, we're done here." 😭🫶

---

🌈 quick reminder: the synopsis shows you calling next and stashing it in $next, and the method does exactly the same thing — returns the next token, or undef when the string runs out. keep both facts in your pocket, they're the same fact twice and that's lowkey cute.

and that's the page!! documented in perl v5.36.0, dated 2022-12-04, from the User Contributed Perl Documentation crew. mwah, go lowercase something. 💖🌸🎀
