commenting large block of code

[bvdang]

Is there a way to comment a large block of code in tcl?

In c/c++, I could use:

#if 0
.
.
.
#endif

In Tcl you can use:
if 0 {
...
}

Braces must be paired.

Good luck

I would be more interested to know the TCL equivalent of:

/**
*
*
*
*
*
*/

In Tcl comments end at the end of the line. Point.

# This is a comment ending at the end of the line

You can split a line by introducing a \ just before the newline (no trailing space):

# This is a comment ending at the end of the line

For Tcl this is one line only.

So you can do

# this is a simili multilines comment

But the usual way remains:

if 0 {
  this is
  a simili
  multilines
  comment
}

does not:

if 0 {
comment
}

still process machine instructions when compiled, whereas:

#~comment

does not?

I think the same could be said in C for:

#if 0
comment
#endif

this being pre-processor commands, and therefore are not compiled into the exe.

Unfortunately I do not know the nuances of the TCL runtime compile so as to know what does wind up in machine instructions.

Thanks for your help.

In:

if 0 {
some stuff
}

Tcl search for matching braces to find the end of the

if

.
But never eval the body.

So you can put unbalanced brackets or quotes at your will.
But unbalanced braces break.
