💅 DESCRIPTION 💅

Lintian::SlidingWindow gives you a way to match some pattern — including a multi line pattern — without needing to fully load the file in memory. no cap. your RAM stays unbothered, your regex stays fed. 🦋

---

👑 CLASS METHODS 👑

new(HANDLE[, BLOCKSUB[, BLOCKSIZE]])

Create a new sliding window by reading from a given HANDLE, which must be open for reading — that's not optional bestie, fr fr.

Optionally run BLOCKSUB against each block. Note that BLOCKSUB should apply transform byte by byte and does not depend of context. so like, keep it local and simple, don't get cute with it 🙈

Each window consists of up to two blocks of BLOCKSIZE characters. yes, up to two — that's the whole slay of the sliding window 🔥

---

🌈 INSTANCE METHODS 🌈

• readwindow — Return a new block of sliding window. Return undef at end of file. 🫶
• "blocksize"
• blocknumber
