Scalastyle proposed rules (Block Checks)

This page contains proposed rules for Scalastyle, for the category Block Checks.

Block Checks

EmptyBlock

Checks for empty blocks.

LeftCurly

Checks for the placement of left curly braces ('{') for code blocks. The policy to verify is specified using property option.

NeedBraces

Checks for braces around code blocks.

RightCurly

Checks the placement of right curly braces ('}') for else, try, and catch tokens. The policy to verify is specified using property option.

AvoidNestedBlocks

Finds nested blocks, i.e. blocks that are used freely in the code. Rationale: Nested blocks are often leftovers from the debugging process, they confuse the reader. For example this Check finds the obsolete braces in public void guessTheOutput() { int whichIsWich = 0; { int whichIsWhich = 2; } System.out.println("value = " + whichIsWhich); } and debugging / refactoring leftovers such as // if (conditionThatIsNotUsedAnyLonger) { System.out.println("unconditional"); }
