ソースコードをHTML表示用に整形するLISPver0.2

ソースコードをHTML表示用に整形するLISPver0.1 - Shammerismの続き。まだエスケープ文字もそのままだが、defparameter をなくして、行を生成する関数を入れてみた。

(defun tr (&rest contents)
  (let ((line "<tr>"))
    (cond ((typep contents 'string)
	   (setf line (concatenate 'string line contents)))
	  ((typep contents 'list)
	   (dolist (x contents)
	     (setf line (concatenate 'string line x)))))
    (concatenate 'string line "</tr>~%")))
       
(defun td (contents &optional is-first-line rows)
  (let ((line "<td"))
    (when is-first-line
      (setf line (concatenate 'string line " rowspan=\"" rows "\""))
      (setf line (concatenate 'string line " style=\""))
      (setf line (concatenate 'string line "width: 1pm; "))
      (setf line (concatenate 'string line "height: 12px; "))
      (setf line (concatenate 'string line "background-color:green;\"")))
    (setf line (concatenate 'string line ">" contents "</td>"))))
       
(defun calc-indent (indent)
  (* 4 indent))

(let ((line-list nil)
      (indent-spaces 0)
      (file-name (first *unprocessed-command-line-arguments*)))
  (format t "<table border='0'>~%")
  (with-open-file (input-stream file-name :direction :input)
		  ;;;; Reading file and structure list by all lines
		  (loop
		   (let ((line (read-line input-stream nil 'eof)))
		     (if (eql line 'eof) (return))
		     (dotimes (i indent-spaces)
		       (format t " "))
		     (setf line-list (append line-list (cons line nil) ))))
		  ;;;; output all lines as html
		  (do ((i 1 (+ i 1)))
		      ((null line-list))
		    (format t (tr (td (write-to-string i))
				  (when (equal i 1)
				    (td ""
					t
					(write-to-string (length line-list))))
				  (td (first line-list))))
		    (setf line-list (cdr line-list)))
		  (format t "</table>~%")))
(quit)

出力結果のサンプルは以下。

<table border='0'>
<tr><td>1</td><td rowspan="10" style="width: 1pm; height: 12px; background-color:green;"></td><td>#include <stdio.h></td></tr>
<tr><td>2</td><td>#include <string.h></td></tr>
<tr><td>3</td><td></td></tr>
<tr><td>4</td><td>int main(int argc, char * args[]){</td></tr>
<tr><td>5</td><td>    char * value;</td></tr>
<tr><td>6</td><td>    printf("Type message:");</td></tr>
<tr><td>7</td><td>    fgets(value, sizeof(value), stdin);</td></tr>
<tr><td>8</td><td>    printf("%s\n", value);</td></tr>
<tr><td>9</td><td>    return 0;</td></tr>
<tr><td>10</td><td>}</td></tr>
</table>

まだエスケープ処理ができていないので、include の行は完全に表示されないしインデントもゼロ。引き続き要改善。
