v2.7.0

Editions

CLI

In order to allow specifying a large number of files to the command-line tool, we now allow providing them via @file argument; this file will contain the names of all files and directories which would otherwise have been specified directly on the command line. A special case of @- is to refer to stdin.

• Add support to expand command-line arguments with @ symbol (#2146) @olafurpg
• Cli: add an option to read file names from stdin (#2162) @kitbellew

Ammonite

• Scalafmt: support @-reloaded Ammonite scripts (#2182) @kitbellew
• TokenTraverser: exclude shebang line in ammonite (#2159) @kitbellew

Consistent formatting of body of definitions and control expressions

Previously, there was a single parameter (newlines.alwaysBeforeMultilineDef) which allowed to force a line break after = if the body of a method occupied multiple lines.

In this release, this parameter is deprecated and replaced with another multivalued parameter; NB: to enable this transition, the default behaviour was changed from forcing a break to allowing a space.

Additionally, when a break is not forced, formatting of body in method definition, variable assignment, control expressions (if, for, while), case clauses has been standardized and controlled via the same parameters (with methods, for backwards compatibility, being optionally configured via a separate parameter).

• Parameters:
  • newlines.beforeMultiline
  • newlines.beforeMultilineDef
• Pull requests:
  • Router: amend folded body to cover infix chains (#2185) @kitbellew
  • Router: standard rule for body of def/if-else/case (#2158) @kitbellew
  • Router: fix when comments follow = in def/val (#2123) @kitbellew

Indentation of infix chains

Previously, indentation with infix chains was applied inconsistently, occasionally failing altogether. In this release, indentation has been made more consistent and applied universally, with parameters documented.

• Parameters:
  • Documented indentOperator
  • Added indentOperator.topLevelOnly
• Pull requests:
  • FormatOps: fix infix indentation (#2180) @kitbellew
  • IndentOperator: move topLevelOnly and document (#2173) @kitbellew

Formatting of lambdas and partial functions

• Changes:
  • Formatting of single-case partial functions like lambdas, breaking after the parameters
• Parameters:
  • newlines.beforeCurlyLambdaParams
  • newlines.afterCurlyLambdaParams
• Pull requests:
  • Router: prefer not breaking before lambda params (#2125) @kitbellew
  • Newlines: rename afterCurlyLambda{,Params} (#2110) @kitbellew
  • Router: allow space after "{" in partial functions (#2108) @kitbellew
