Heading 2 Core API
  class mt-12
Markdown
  **Note:** The Core API is designed for maximum portability and is not intended to be directly consumed.

  For most projects you'll want to use the [Document API](#document-api) instead.
  It provides an ergonomic wrapper around the Core API and lets you focus on parsing
  your documents.

Heading 3 terrace_linedata_t
  class mb-4 mt-12
Markdown
  This struct holds information about each line as it is parsed. Mutated each time [terrace_parse_line()](#terrace-parse-line) is called. Not intended to be used directly.
  Use the relevant `terrace_` functions from the [Document API](#document-api) instead.
CodeBlock c
  // Holds the parsed information from each line.
  typedef struct terrace_linedata_s {
    // Which character is being used for indentation. Avoids having to specify it on each terrace_parse_line call.
    char indent;
    // How many indent characters are present in the current line before the first non-indent character.
    unsigned int level;
    // The number of characters before the start of the line's "head" section.
    // (Normally the same as `level`)
    unsigned int offsetHead;
    // The number of characters before the start of the line's "tail" section.
    unsigned int offsetTail;
  } terrace_linedata_t;

  | Parameter      | Type                  | Description
  | -------------- | --------------------- | -----------------------------------------------------------------------
  | indent         | const char            | The character used for indentation in the document. Only a single character is permitted.
  | **@returns**   | [terrace_linedata_t](#terrace-linedatat) | A terrace_linedata_t struct with the specified indent character and all other values initialized to 0.

  Initialize a [terrace_linedata](#terrace-linedatat) struct with default values to pass to [terrace_parse_line()](#terrace-parse-line).

  | lineData       | [terrace_linedata_t](#terrace-linedatat)* | A pointer to the terrace_linedata_t struct to store information about the current line in.

  Core Terrace parser function, sets `level`, `offsetHead`, and `offsetTail` in a [terrace_linedata](#terrace-linedatat) struct based on the current line.
