New features & improvements

• Added compability for Crystal 0.34 (BC with Crystal 0.33). See #138 (thanks @bcardiff)
• Added ability to configured globs and exclude paths to sources globally (see #125):

# .ameba.yml

Globs:
  - **/*.cr
  - !lib

Excluded:
  - spec
  - src/server/*

• Style/RedundantReturn rule was extended to catch redundant returns in binary operators. See 946ec67
• Lint/LiteralInInterpolation rule now reports multiple nodes and points to the specific literal locations. See 04497fe
• AST::NodeVisitor is now a default for all rules, which reduces a good portion of a boilerplate. See 1a0468c

New rules added:

• Style/RedundantNext - disallows redundant next expressions. See #134
• Lint/SharedVarInSpawn - disallows using shared variables in fibers, which are mutated during iterations. See #135

Bugfixes

• Block params in macro were mistakenly reported as shadowed local var. This is now fixed aff723b

v0.11.0

New features & improvements

• --gen-config now does not generate a todo file if there are no linting issues, see 2704a0d
• A new AST structure typeof is added to the list of scope, so rules now properly report unused assignment, shadowed variables etc, see 677c757

typeof(begin
  foo = 1 # unused variable
  # ...
 end)

Note: Such kind of structure is usually used as type specs when the compiler can report a problem at the compilation step instead of runtime.

• Ameba can now lint in parallel, see #118
• New rule: RedundantWithIndex, see #120
• New rule: RedundantWithObject, see #121

• Generated TODO file could have duplicated sections in yaml file. This is fixed by 1115965, 4ae0195
• A custom bin/ameba.cr run file could be deleted even it was already created by the user. This is fixed by 4a54f6d
• Previously Ameba reported false positiveness if argument is shadowed by instance variable:

def bar(@foo)
  @foo.try do |foo|
  end
end

This is fixed by 6b56c87
