I grew tired of "writing" C++ definition stubs by copying around declarations from (interface) header files. Thus I wrote this extension, which helps generating said stubs from a header file. Additionally it allows creating the necessary files for an implementation of a given interface. Multiline declarations and nested classes/namespaces are supported. Still not perfect, but should work for the most common use cases.

The extension is automatically loaded when using the C or C++ language. The following commands are provided while a C/C++ header file is open in the editor:

• codegen-cpp: Generate interface implementation source/header files : Parses the currently opened header file and generates implementation stubs for all available interfaces. The names of the interface implementations can be provided via the UI.

• codegen-cpp: Generate interface implementation source/header stub(s) for selection: Same as above, but only for a certain text selection in the currently opened header file

  

• codegen-cpp: Generate source file from header: Parses the currently opened header file and generates source stubs for the given declarations.

• codegen-cpp: Generate source stub(s) for selection: Same as above, but only for a certain text selection in the currently opened header file

  

• codegen-cpp: Generate abstract factory(s) from header: Parses the currently opened header file and generates abstract factory interfaces for the given classes.

• codegen-cpp: Generate abstract factory(s) from header for selection: Same as above, but only for a certain text selection in the currently open header file

Additional features:

• Source file auto completion: Provides completion items for missing defintions in a source file (namespace aware). Displaying the completion items can also be triggered by typing a configurable character (default: .) in an empty line. Currently this only works if there is a header file with a matching name next to the current source file.
• Merging header/source files: in case new file is generated, but one with the same name already exists, a refactoring preview is displayed in VS Code to help merging the files manually (configurable)
• Directory Quick Picker: You can select the output directory of the created files easily and fastly via a VS Code quick pick (configurable)
• custom, configurable file headers for the generated files
• names of to newly created files can be either entered via an input field or deduced from a namepattern

Can be reported here. Contributions are also welcome in any form.

• using statements are not evaluated
• preprocessor macros after class specifier are not working
• enum classes are deserialized as classes
• default constructors/destructors are not detected

• Prettifying the generated output
• more configuration possibilities (e.g. for namespaces)
• ...

• updated dependencies

• feat: Language support for C
• feat: Stub definition auto completion in a source file in case there is a header file with matching name next to it
• fix: enable commands also for custom header extensions

• reworked directory quick pick
• fix: missing header guards

• Rerelease due to faulty bundling, new commands are not available

• added: Creating abstract factories from a header
• added: Namepattern support for interfaces/abstract factories
• fix: UI directory selection not working
• fix: Name input dialogue is only shown for interfaces when generating implementation stubs

• fixed: crash when merging a previously empty file

• fix: missing namespaces in header when using prepended mode

• fix: No longer generate empty namespaces
• fix: Error handling:
  • warn instead of silently fail
  • warn if nothing is generated
• fix: directory QuickPick:
  • does no longer automatically change the filter value when the active item changes
  • instead update the filter only when a new item with different label is selected (with ENTER)
  • added a "GoBack" item (..) to quickly select the parent directory of the current filter value

• added: configuration for the namespace serialization mode
• added: support for structs
• fixed: new line artificats when merging source files

• added: setting to choose how output directories are selected (None/QuickPick/UI dialogue)
• improved directory QuickPick handling

• fixed: Serialization of nested classes
• fixed: Too many remaining new line feeds when merging source files

Initial release for testing the two generator features: source stubs and generating interface implementing stubs
