[Question] don't know how to write a surrounded comment macro

[Gilvin]

hi all. this confused me for 5 days..

assume that there is a line of code i modified (added, removed):

Code: [Select]

printf ("hello world\n");
and i want a macro that when i select the line and press a fn key (F8, F9...etc), it will be like this:

(x x x is a constant number, never be changed, but yyy will be changed whenever i have to)

Code: [Select]

//[-start-yymmdd-AA0xxx0yyy-modify]//
printf ("hello world\n");
//[-end-yymmdd-AA0xxx0yyy-modify]//
or

Code: [Select]

//[-start-yymmdd-AA0xxx0yyy-add]//
printf ("hello world\n");
//[-end-yymmdd-AA0xxx0yyy-add]//
after 5 days after work trying, the result is a failure... can someone teach me, thanks

Which parts of the task are you having trouble with?

Here is something that may help you out.  This is a helper function I use to surround the current line block selection with a "before" and "after" line passed as arguments:

Code: [Select]

/**
 * Surrounds the current LINE type selection with the <i>sBefore</i> and
 * <i>sAfter</i> lines.  For example 'SurroundLineBlock("#if 0","#endif")'.
 *
 * @param sBefore    Line to insert before the current selection.
 * @param sAfter     Line to insert after the current selection.
 */
static void SurroundLineBlock( _str sBefore, _str sAfter )
{
   if ( _select_type() == 'LINE' )
   {
      typeless p;
      _save_pos2( p );

      _begin_select();
      up();
      insert_line( sBefore );

      _end_select();
      insert_line( sAfter );

      _deselect();

      _restore_pos2( p );
   }
   else
   {
      message( 'No line block.' );
   }
}

Next you can construct before and after strings to match your template, and pass them to this routine to surround the line block selection.

i've tried using alias to do the job, but when i turned on the "surround with" checkbox, slickedit wouldn't expand my alias, so i tried again using macro

Which parts of the task (of writing a macro to do this) are you having trouble with?
Does the helper function I posted enable you to finish writing a working macro?
If not, are there specific things that are problematic?

[Gilvin]

it helps. the surround with in your macro is great. but i don't know how to add date in YYMMDD format, in slickedit there's a default MMDDYY, and i don't know how to modify it

@Gilvin: Try this add. helper macro I'm using:

Code: [Select]

/**
 * get compact date
 *  
 * @param delim   opt. delimiter of date tokens
 * @param yyyy    true: 4 digit year - false: 2 digits
 * @param lzero   leading zero of each date token/number
 *
 * @return  compact date string
 */
static _str getcdate ( _str delim = '', boolean yyyy = false, boolean lzero = true )
{
   _str month, day, year;
   parse _date() with month'/'day'/'year;
   if (lzero && length(month)<2) month='0'month;
   if (lzero && length(day)<2)   day='0'day;
   if (length(year)>2 && !yyyy)  year=substr(year,3);
   return ( year delim month delim day );
}

Your desired format is returned when using the defaults e.g. _str mydate = getcdate();
Good luck, HS2
