Markdown Hardbreak Trailing Spaces Count Tool

Description

Count trailing ASCII spaces on a line without CR or LF and set hardBreak when there are at least two.

Text positions can be measured in UTF-16 code units, Unicode code points, grapheme clusters, or modeled display columns. These coordinates are not interchangeable. Invisible markers and delimiter policies can also affect interpretation even when a string looks unchanged, so the chosen representation needs to stay explicit.

Count trailing ASCII spaces on a line without CR or LF and set hardBreak when there are at least two.

When to use this tool

Use Markdown Hardbreak Trailing Spaces Count when you need the stated marker, coordinate, delimiter, or normalization operation under an explicit text representation.

How to use the tool and how it works

Enter line. Use the units and conventions below.
Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
Read trailingSpaces, hardBreak. Inspect hardBreak before interpreting the associated values.

Limitations and assumptions

This is one lexical hard-break condition, not full Markdown parsing. Blank-line context, block structure, escaped syntax, and end-of-document handling can affect the rendered result.
The field tables state structural bounds; the mechanics also specify cross-field constraints. Malformed inputs and unsupported domains cause errors. A successful false flag, empty branch value, or zero placeholder has the meaning stated above and is distinct from an input error.

Alternative or Complementary methods

Choose the coordinate system required by the consumer. Use a full parser, renderer, or segmentation method when a local marker or delimiter rule cannot determine the complete text behavior.
