Yes, sometimes the point seems to be to make a one-liner as short and cryptic as possible. It celebrates the brilliance and creativity of the creator. The reader stands back in awe, in amazement that the one-liner apparently works perfectly, but with only a vague idea of how it works. In contrast, a longer, spelled-out style is often easier to understand and more practical, but may seem pedestrian in comparison.

Maybe it's like the difference between the unpredictable, exciting attacking style of a Mikhail Tal vs the boring, grind-it-out style of a Tigran Petrosian. They both became world chess champion. But which games are more enjoyable to play through? Those of Mikhail Tal.

Of course, the best result is the one-liner that is also very easy to understand. Just like the best chess player is the one who can combine different styles.

Back to work. Smilie

__________________________________________________________________________________________________________________________________________________

NAME

       Tk_GetJoinStyle, Tk_NameOfJoinStyle - translate between strings and join styles

SYNOPSIS

       #include <tk.h>

       int
       Tk_GetJoinStyle(interp, string, joinPtr)

       const char *
       Tk_NameOfJoinStyle(join)

ARGUMENTS

       Tcl_Interp *interp (in)		 Interpreter to use for error reporting.

       const char *string (in)		 String containing name of join style: one of "bevel", "miter", or "round".

       int *joinPtr (out)		 Pointer to location in which to store X join style corresponding to string.

       int join (in)			 Join style: one of JoinBevel, JoinMiter, JoinRound.
_________________________________________________________________

DESCRIPTION

       Tk_GetJoinStyle places in *joinPtr the X join style corresponding to string, which will be one of JoinBevel, JoinMiter, or JoinRound.  Join
       styles are typically used in X graphics contexts to indicate how adjacent line segments should be joined together.  See the X documentation
       for information on what each style implies.

       Under  normal circumstances the return value is TCL_OK and interp is unused.  If string does not contain a valid join style or an abbrevia-
       tion of one of these names, then an error message is stored in interp->result, TCL_ERROR is returned, and *joinPtr is unmodified.

       Tk_NameOfJoinStyle is the logical inverse of Tk_GetJoinStyle.  Given a join style such  as  JoinBevel  it  returns  a  statically-allocated
       string corresponding to join.  If join is not a legal join style, then "unknown join style" is returned.
