Re^6: Loading all files in a dir with use via for loop

~~That does work because of the super-low-precedence of 'or'.~~Actually, it doesn't work. The if wants to evaluate all of the following expression. It's not very readable, ~~though~~either.~~: someone who doesn't understand the lower-precedence-ness of 'or' (compared to '||', especially). To them it would look like you should~~It will try to eval $PAGE if one of the two or statements is true. Also, you don't need to specify main-> for nopageerror.

For clarity, I suggest one of these:

# whoops, syntax errors, thanks to Roy Johnson
## ( eval "$PAGE" if main->can($PAGE) ) or nopageerror;

## or... 
#( eval "$PAGE" if main->can($PAGE) )
#  or nopageerror;

## or...
if ( main->can($PAGE) ) {  eval $PAGE }
else {  nopageerror }

predicate-`if` is not an operator, it is a statement modifier. It is not part of an expression, so you can't parenthesize it. Your first suggestion is a syntax error. Caution: Contents may have been coded under pressure.	[reply] [d/l]

You are correct radiant.matrix. I'm always forgetting the \|\|/or methods. Simularily I confuse the eq and = and == thus causing scripting errors.... The simplest things are generally the easiest to over look and cause the most problems.	[reply]
