    Examples
    diff
     func (c *ConverterImpl) Convert(source execution.Input) execution.Output {
     var structsOutput execution.Output
-    var pString *string
     if source.Nested.Name != nil {
         xstring := *source.Nested.Name
-        pString = &xstring

     }
-    structsOutput.Name = pString
     return structsOutput
 }

     func (c *ConverterImpl) ConvertPToP(source []*int) []*int {
     var pIntList []*int
     if source != nil {
         pIntList = make([]*int, len(source))
         for i := 0; i < len(source); i++ {
-            var pInt *int
             if source[i] != nil {
                 xint := *source[i]
-                pInt = &xint
+                pIntList[i] = &xint
             }
-            pIntList[i] = pInt
         }
     }
     return pIntList
 }

v1.4.0 ​

internals:

  • Require the examples to be up-to-date via CI (#136)
  • Fix file permissions in tests (#136)

v1.3.2 ​

Change generated directory permissions from 777 -> 755 and generated file permissions from 777 -> 644. This only affects newly created files and directories. Existing files and directories will keep their current permissions. (#128 via #129)

v1.3.1 ​

Fix nil map conversion. A nil map of will be converted to a nil map of the target type. Previously, the target map was instantiated via make with a 0 size. (#126 via #127)

v1.3.0 ​

internals:

  • Migrate documentation to vitepress (#118)

v1.2.0 ​

  • Support using unexported fields, methods and functions when they are accessible from the output:package (#104 via #107)
  • Fix ignored field settings for conversions from non pointer to pointer types (#104 via #107)
  • Improve error messages for *T to T conversions (#105 via #106)
  • Error on overlapping internal sub methods (#105 via #106)

internals:

v1.1.1 ​

Fix a panic when using the error type inside the conversion.

(#102 via #103)

v1.1.0 ​

v1.0.0 ​

  • Major rework of documentation. See settings (#92)
  • Rework of the CLI (#92)
  • Improve handling of boolean flags, allow disabling these settings for single methods. See define (#92)
  • Add output:file output:pattern settings: output (#92)
  • Remove deprecated mapExtend mapIdentity: migrations (#92)
  • Refactor internals for upcoming features (#92)

See migrations for instructions to migrate to this version. If you have problems with this release please create a ticket in this project.

v0.18.0 ​

Add skipCopySameType, this setting instruct Goverter to skip copying instances when the source and target type is the same.

(#86 via #87)

v0.17.5 ​

Prevent unused variables in generated code when empty structs are used

(#82 via #83)

v0.17.4 ​

Fix endless loop when converting nested recursive types.

(#73 via #74)

v0.17.3 ​

Fix panic when generating a conversion method containing the type map[string]interface{}. (#71 via #72)

v0.17.2 ​

Readd go1.16 support for building goverter, it broke with v0.17.1.

(#69 via #70)

v0.17.1 ​

Fix generation of types with generic arguments (#66 via #67)

v0.17.0 ​

v0.16.0 ​

v0.15.0 ​

v0.14.0 ​

  • Prevent value copying of source struct pointers if possible. This should fix "go vet copylocks" warnings, because some structs should not be copied. See (#39 via #56)
  • Due to the change above, the generated code will look different, because goverter now splits internal converter methods differently. The overall behavior of the implementation shouldn't change. (#56)
  • Error on overlapping field mappings. This doesn't change how config is evaluated, but it does now error when field mapping config like goverter:map is at the wrong converter method and would be ignored. (#56)

v0.13.0 ​

  • Fix docs links in error messages
  • Allow using external packages in map (#47 via #50)
  • Allow returning an error in map (#43 via #50)
  • Error on misconfiguration (#8 via #51)

v0.11.1 ​

Fix pointer slice conversion

(#40 via be3874)

v0.11.0 ​

Allow passing self in mapExtend method

(#38 via eb1337)

v0.10.1 ​

  • Improve error message on compile errors (#35)
  • Fix goverter:mapIdentity with pointer types (#36 via feeafb)

v0.10.0 ​

By default, goverter will fail if you don't ignore all unexported fields. To automatically ignore all unexported fields, you can enable ignoreUnexported (#31 via #32)

v0.9.0 ​

Add wrapErrors (#29)

v0.8.1 ​

Use extend method when converter method with same method exists

(#26 via 12cc64)

Error using extend on unexported method (#17)
