Subject [jira] [Commented] (CONFIGURATION-477) PropertyListConfiguration cannot deal with comments
Date Tue, 21 Feb 2012 12:19:34 GMT

    [ https://issues.apache.org/jira/browse/CONFIGURATION-477?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13212534#comment-13212534
] 

Emmanuel Bourg commented on CONFIGURATION-477:
----------------------------------------------

The specification I used to implement it didn't mention that comments were allowed.

http://www.gnustep.org/resources/documentation/Developer/Base/Reference/NSPropertyList.html

I checked the plist parser in the OpenStep code and it does indeed skip C-style comments (both
block comments and line comments):

{code:java}
/*
 *	Property list parsing - skip whitespace keeping count of lines and
 *	regarding objective-c style comments as whitespace.
 *	Returns YES if there is any non-whitespace text remaining.
 */
static BOOL skipSpace(pldata *pld)
{
  unsigned char	c;

  while (pld->pos < pld->end)
    {
      c = pld->ptr[pld->pos];

      if (GS_IS_WHITESPACE(c) == NO)
	{
	  if (c == '/' && pld->pos < pld->end - 1)
	    {
	      /*
	       * Check for comments beginning '/' followed by '/' or '*'
	       */
	      if (pld->ptr[pld->pos + 1] == '/')
		{
		  pld->pos += 2;
		  while (pld->pos < pld->end)
{code}
