I was going through some js code a few months ago and every function in a module had
return;as its first line. And that module was imported into 4 or 5 scripts.You folks have clearly not met first year CS students. Screenshots code
If you’re in a language that supports it, please don’t use
if (false)useif ($disallowAllUsers = false && $whateverTheRealConditionIs)Never seen this, what language or buildsystem is this?
That specific language is PHP, but the tip is applicable in any language that supports inline assignment.
if (true === $wantToCauseErrorsForFun) { badOldFunction(); }
The assignment syntax is too close to comparison, which is what is more typical in that position. I would recommend
const bool _isFeatureEnabled = false; if (_isFeatureEnabled && ...)if not a proper feature flag (or just remove the code).
bonus points if you use a different variable every file so they have to go through and change every instance if they want to make changes
I don’t see the need for an if block or renaming the function and leaving it there. It is extra unnecessary work for the compiler. Comments are probably the best way. Might also copy the current file, put the original in some folder like “old”, and delete the old code inside the new copy.
Comments are the worst as they are ignored by refactoring. That’s the reason if (false) is actually really good for temporarily disabled code.
I never thought of that. That’s quite smart!
On a modern computer dead code analysis with constant folding should be nearly unnoticeable when compiling a large project
what about relying on the persistent undo history in vim?

In Python you put it in a multiline string, since it has those but not multiline comments.
