Subject: LaTeX export filter
Date: Sat, 24 Mar 2018 22:24:59 +0530	[thread overview]
Message-ID: <218D99DB-E8AE-4968-98E8-7E35BE022E7E@agrarianresearch.org> (raw)

Let me start by confessing my limited knowledge of lisp.

I am trying to write a LaTeX export filter that should replace all table rows with cells having entries such as <3cid4> by \cmidrule{lr}{3-4}

The idea is to have a table row of this kind

| <2cid3> |           <4cid5> |        <6cid7>             |                   |                                           |                   |                   |

Which should be exported to 

\cmidrule(lr){2-3} \cmidrule(lr){4-5} \cmidrule(lr){6-7}

This is as far as I have gone.

------

(defun org-export-cmidrule-filter-latex (row backend info)
  (while (string-match
          "\\(<\\([0-9]+\\)cid\\([0-9]+\\)?>[[:blank:]]*\\([^&]+\\)\\)" row)
    (let ((start (string-to-number (match-string 2 row)))
          (end (or (match-string 3 row) "l")))
      (setq row (replace-match
                 (format "\\\\cmidrule(lr){%s-%s}" start end)
                 nil nil row 1))
      (while (string-match "& \\| \\\\\\\\" row 0)
        (setq row (replace-match "" nil nil row))
        (decf start))
      )
    )
  row)

------

The above filter works if I have only one or two <[0-9]cid[0-9]> strings in a row. It does not pick up the third <[0-9]cid[0-9]> string.

I would greatly appreciate if anyone could help improve this filter.
