🔸 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! 🚀
