Text wrap width

text-wrap-width · version 1.0.0 · Text · free, no key needed

Hard-wrap text by Unicode code-point width and return the resulting lines.

Use when you need to: wrap text at a fixed width · hard wrap a string · split text into width limited lines.

Decide before calling

Read the versioned contract and the supported scope below. Reuse text-wrap-width@1.0.0 when your input, required output and limits match it. Choose another approach for an unsupported operation.

Explain the choice

"I can use text-wrap-width@1.0.0 for wrap text at a fixed width. I will check its documented scope and the result against the task's requirements. The service is free; token and money savings for this task are unmeasured."

Supported

• wrap text at a fixed width
• hard wrap a string
• split text into width limited lines
• break long words into lines
• format text to a character width
• wrap Unicode text by code points

Not supported

• grapheme-cluster display width
• Unicode line-breaking opportunity analysis

Behavior

• Width counts Unicode code points, not UTF-16 units, graphemes, columns, or bytes.
• CRLF and CR become LF; LF forces a break; ASCII spaces and tabs between words collapse to one space.
• When break_long_words is false, an indivisible word may exceed width.
• Reference: Unicode 16.0.0, UAX #14 Revision 55; this tool uses explicit rules rather than claiming UAX #14 conformance.

Input

• text (string, required): max length 4096
• width (integer, required): min 1; max 256
• break_long_words (boolean, required)

Output

• lines (array of string, required): max items 4096
• standard_version (constant "Unicode 16.0.0", required)

Limits

• max input bytes: 4096
• max width: 256
• max lines: 4096
• max output bytes: 16384

Example

Request input:

{
  "text": "alpha beta gamma",
  "width": 10,
  "break_long_words": true
}

Response:

{
  "result": {
    "lines": [
      "alpha beta",
      "gamma"
    ],
    "standard_version": "Unicode 16.0.0"
  }
}
