# stx-source

(stx-source stx) -> locat | #f
  stx := syntax

:::

Returns the source location of a syntax object AST stx.

The locat structure includes the container and filepos, accessed by ##locat-container and ##locat-filepos. The filepos has line and column information, accessed with ##filepos-line and ##filepos-col.

# stx-wrap-source

(stx-wrap-source stx src) -> syntax
  stx := any
  src := locat

:::

Produces a new syntax object with source location src if stx is not wrapped as an AST already, otherwise returns stx unchanged.

The locat structure can be constructed with (##make-locat container filepos filepos-end), where:

• container is a string denoting a file path, or a list containing a symbol denoting the provenance (string, port, etc.).
• filepos can be constructed with (##make-filepos line col off).
• filepos-end can be #f if the location is a position, or a number similar to filepos indicating the end position (not included) if the location is a range.
