;;; Commentary:
;;;
;;; This module provides utility functions to operate on `table' ASTs. It is
;;; partly based on code from Scribe 1.1a.
;;;
;;; Code:
(skribilo-module-syntax)
(define (table-column-count t)
;; Return the number of columns contained in table T.
(define (row-columns row)
(let loop ((cells (markup-body row))
(nbcols 0))
(if (null? cells)
nbcols
(loop (cdr cells)
(+ nbcols (markup-option (car cells) :colspan))))))
(let loop ((rows (markup-body t))
(nbcols 0))
(if (null? rows)
nbcols
(loop (cdr rows)
(max (row-columns (car rows)) nbcols)))))
