From: Chris Wagner <chris.wagner <at> cambridgeconsultants.com> To: 25608 <at> debbugs.gnu.org Subject: bug#25608: CC Mode 5.33 (C/l); Incorrect syntactic information and indentation after multi-line comment with parenthesis or keywords Date: Thu, 2 Feb 2017 13:45:36 +0000
[Message part 1 (text/plain, inline)]
Hello,
With the following c code:
/*-----------------------------------------------------------------------------
(c) Copyright notice containing open parentheses
-----------------------------------------------------------------------------*/
/*---------------------------------------------------------------------------*/
the last line is indented incorrectly, as the identified syntactic
information is ((topmost-intro-cont 1) (comment-intro)). I think it
should be ((topmost-intro 1) (comment-intro)), which the following code
correctly identifies:
/*-----------------------------------------------------------------------------
Non parenthesis language
-----------------------------------------------------------------------------*/
/*---------------------------------------------------------------------------*/
Similarly, if there is a keyword in the comment, the next comment is
incorrectly identified and indented:
/*-----------------------------------------------------------------------------
(c) Copyright notice containing open parentheses
Line containing keyword for
-----------------------------------------------------------------------------*/
/*---------------------------------------------------------------------------*/
Note that indenting the comment region removes the problem:
/*-----------------------------------------------------------------------------
(c) Copyright notice containing open parentheses
Line containing keyword for
-----------------------------------------------------------------------------*/
/*---------------------------------------------------------------------------*/
indents correctly.
Best regards,
Chris
