Adding Comments to Expressions

[TaraM]

Question

Is it possible to add a comment to an expression used in a Filter or Formula?

Answer

Yes, once you have a valid expression, just use // followed by your comment on the next line.

/* you can also

add blocks of comments

into the formula */

i use use this technique when I comment out old code in place of new code.

You don't need to go to the next line.

You thus have 2 ways:

- comment in line with // : anything after this on this line is commented

      you can use it to place in comment a full line or comment at the end of a line

- comment by block with /* your comment */ : anything in between this is commented, whether it's on the same line or not.

     you can use it to comment several lines at a time, or just a portion of a line (in that case, be careful about content in quotes, plus it's not very readable)

You could also do that by using 'Show Annotation' option in the Tool's 'Annotation' configuration.

I recently learned a little trick:

If you add in a couple of slashes, then you can make it so that a single character can be used to toggle between commenting code out or including it.

//*

you can also

add blocks of comments

into the formula //*/

When the first slash is removed, the /* takes effect, which makes the last red slashes into part of the block comment. When it is added in, it comments out the initial * which indicates the start of the comment and the bottom // comment out the end block comment */

I thought it was a clever trick.
