Text lines chunk

text-lines-chunk · version 1.0.0 · Text · free, no key needed

Split parsed lines into consecutive chunks of size lines each.

Use when you need to: text lines chunk · chunk lines · split lines by size.

Supported

• text lines chunk
• chunk lines
• split lines by size

Not supported

• overlap chunks
• bytes chunk
• stream

Behavior

• Split on CR LF, LF, or CR. Do not treat other Unicode separators as line breaks.
• A trailing terminator does not create an extra empty line.
• Empty document -> zero lines, trailing_terminator false.
• A document that is only a terminator -> one empty line, trailing_terminator true.
• A document with no terminator -> last line kept, trailing_terminator false.
• Preserve empty lines in the middle.
• Output reconstruction uses LF. If the result has at least one line, append a trailing LF iff the selected window includes the original trailing terminator or includes a line that was followed by a separator in the source.
• No trimming, case folding, Unicode normalization, or locale rules.
• size is a JSON integer, 1 <= size <= max_lines.
• Chunks are consecutive, last chunk may be shorter.
• Empty input -> chunks [].
• If the number of chunks would exceed 512, reject.
• Each chunk string uses LF reconstruction; a non-final chunk always has a trailing LF if it is non-empty; the final chunk follows original trailing-terminator rules.

Input

• text (string, required): max length 256000
• size (integer, required): min 1; max 10000

Output

• chunks (array of string, required): max items 512
• lines_in (integer, required)
• chunk_count (integer, required)

Limits

• max input bytes: 256000
• max lines: 10000
• max chunks: 512

Example

Request input:

{
  "text": "a\nb\nc\n",
  "size": 2
}

Response:

{
  "result": {
    "chunks": [
      "a\nb\n",
      "c\n"
    ],
    "lines_in": 3,
    "chunk_count": 2
  }
}
