class Bindgen::Processor::SanityCheck

Overview

Does sanity-checks on the graph. If any check fails, a message written to STDERR and the process is exited.

Checks are as follows:

Defined in:

bindgen/processor/sanity_check.cr

Constant Summary

ARRAY_BINDING_TYPES = {"Binding::CrystalSlice", "Binding::CrystalArray"}

Binding types of C arrays, defined in glue.cr.

ARRAY_RX = /^(?:Slice|BindgenHelper::ArrayView)\((.+)\)$/

Regular expression for the Crystal type of a C array of other than built-in types, capturing the element type: Slice(Color)

CAMEL_CASE_RX = /^[A-Z_][A-Za-z0-9_]*$/

Regular expression for a camel-cased symbol

CONSTANT_RX = /^[A-Z_][A-Z0-9_]*$/

Regular expression for a CONSTANT

ENUM_FLAG_ALL = "All"

The all-flags constant in a flag-enum

ENUM_FLAG_NONE = "None"

The no-flags constant in a flag-enum

ENUMERABLE_RX = /^(?:Enumerable|Tuple)(?:\([A-Za-z0-9_():*{}, ]*\))?$/

Regular expression for a Crystal Enumerable typename, which may be of tuples: Enumerable({K, V})

TODO support other Crystal stdlib types (which might not correspond to any C++ type at all)

Log = ::Log.for(self)

Does sanity-checks on the graph. If any check fails, a message written to STDERR and the process is exited.

Checks are as follows:

  • Name of enums, libs, structures, classes, modules and aliases are valid
  • Name of methods are valid
  • Enumerations have at least one constant
  • Enumeration constants are correctly named
  • Flag-enumerations don't have All nor None constants
  • Crystal method overloads are unambiguous
  • Method arguments and result types are reachable
  • Variadic methods are directly bound
  • Alias targets are reachable
  • Class base-classes are reachable
  • Structure fields are of a supported and reachable type
METHOD_NAME_RX = /^[a-z_][A-Za-z0-9_]*[?!=]?$/

Regular expression describing a method name

OPERATOR_METHOD_NAME_RX = /^([\+\-\*\/\%\&\|\^\>\<\~]|\<\<|\>\>|[\!\=\<\>]=|=[\<\>]|\[\])$/

Regular expression describing a operator method name

TYPE_DECL_RX = /^[A-Z_][A-Za-z0-9_]*(?:\(\*?[A-Z_][A-Za-z0-9_]*(?:, \*?[A-Z_][A-Za-z0-9_]*)*\))?$/

Regular expression for a type declaration, possibly generic
