🔸 TL;DR
Postfix completions let you write the value first, then transform it with a suffix like .var, sout, .try, etc. Type less, flow more. ⚡
🔸 WHAT IS POSTFIX COMPLETION?
▪️ Type an expression, add a short suffix, hit Tab/Enter, and IntelliJ reshapes it for you.
▪️ Keeps your eyes on the expression, not the boilerplate.
▪️ Works in Java/Kotlin and more, and is customizable. 🛠️
🔸 CORE SNIPPETS YOU’LL USE DAILY
▪️ .var → declare a local var
getUser().profile().address().var // → var address = getUser().profile().address();
▪️ sout → print value
user.getId()sout // → System.out.println(user.getId());
▪️ .try → wrap in try/catch
riskyCall().try
// →
try {
riskyCall();
} catch (Exception e) {
e.printStackTrace();
}
▪️ .if / .ifn → guard clauses
order.if // → if (order != null) { … }
order.ifn // → if (order == null) { … }
▪️ .nn / .null → not-null / null checks
customer.nn // → if (customer != null) { … }
customer.null // → if (customer == null) { … }
▪️ .for / .fore → loops
items.for // → for (Item item : items) { … }
items.fore // → items.forEach(item -> { … });
▪️ .cast → cast expression
obj.cast // → ((TargetType) obj)
▪️ .return → return expression
result.return // → return result;
▪️ soutv → print with name & value
total.soutv // → System.out.println("total = " + total);
🔸 HOW TO ENABLE / TUNE IT
▪️ Settings → Editor → General → Postfix Completion ✅
▪️ Toggle languages, enable/disable specific templates, add your own.
▪️ Learn a handful, then add more as muscle memory builds. 💪
🔸 WHY IT MATTERS
▪️ Fewer cursor jumps, fewer parentheses juggling.
▪️ Faster refactoring from value-first thinking.
▪️ Cleaner, more consistent scaffolding.
🔸 TAKEAWAYS
▪️ Start with .var, sout, .try, .if — biggest wins.
▪️ Customize to match your coding style.
▪️ Practice on real code until it becomes second nature. ⚡
Happy typing! 🚀
