multiLineLocals

default: "smart"

Control how to insert whitespace between multiple locals in a function.

Available option values:

• "never"
• "overflow"
• "smart"
• "wrap"
• "always"

All the examples below assume the print width is 45.

"never"

All locals will be printed in the same line, regardless of the print width.

(module
  (func (local i32) (local i64) (local f32))
  (func (local i32)
    (local i64) (local f32))
  (func (local $1 i32) (local $2 i32) (local $3 i32))
  (func (local $1 i32)
    (local $2 i32) (local $3 i32)))

↓

(module
  (func
    (local i32) (local i64) (local f32))
  (func
    (local i32) (local i64) (local f32))
  (func
    (local $1 i32) (local $2 i32) (local $3 i32))
  (func
    (local $1 i32) (local $2 i32) (local $3 i32)))

"overflow"

If failed to print all locals in the same line within the print width, each local will be printed in its own line.

(module
  (func (local i32) (local i64) (local f32))
  (func (local i32)
    (local i64) (local f32))
  (func (local $1 i32) (local $2 i32) (local $3 i32))
  (func (local $1 i32)
    (local $2 i32) (local $3 i32)))

↓

(module
  (func
    (local i32) (local i64) (local f32))
  (func
    (local i32) (local i64) (local f32))
  (func (local $1 i32)
    (local $2 i32)
    (local $3 i32))
  (func (local $1 i32)
    (local $2 i32)
    (local $3 i32)))

"smart"

"smart" will detect if there's a line break between the first local and the second local in original code.

If there's a line break, it behaves like "always", though it doesn't exceed the print width:

(module
  (func (local i32)
    (local i64) (local f32)))

↓

(module
  (func
    (local i32)
    (local i64)
    (local f32)))

If there's no line break, it behaves like "overflow", even if there're line breaks between the rest locals:

(module
  (func (local i32) (local i64)
    (local f32))
  (func (local $1 i32) (local $2 i32) (local $3 i32)))

↓

(module
  (func (local i32) (local i64) (local f32))
  (func
    (local $1 i32)
    (local $2 i32)
    (local $3 i32)))

"wrap"

Locals will be printed in the same line until the print width is exceeded, then insert a line break.

(module
  (func (local i32) (local i64) (local f32))
  (func (local i32)
    (local i64) (local f32))
  (func (local $1 i32) (local $2 i32) (local $3 i32))
  (func (local $1 i32)
    (local $2 i32) (local $3 i32)))

↓

(module
  (func
    (local i32) (local i64) (local f32))
  (func
    (local i32) (local i64) (local f32))
  (func
    (local $1 i32) (local $2 i32)
    (local $3 i32))
  (func
    (local $1 i32) (local $2 i32)
    (local $3 i32)))

"always"

All locals will be printed in their own lines.

(module
  (func (local i32) (local i64) (local f32))
  (func (local i32)
    (local i64) (local f32))
  (func (local $1 i32) (local $2 i32) (local $3 i32))
  (func (local $1 i32)
    (local $2 i32) (local $3 i32)))

↓

(module
  (func
    (local i32)
    (local i64)
    (local f32))
  (func
    (local i32)
    (local i64)
    (local f32))
  (func
    (local $1 i32)
    (local $2 i32)
    (local $3 i32))
  (func
    (local $1 i32)
    (local $2 i32)
    (local $3 i32)))
