Process when translating existing code from Delphi to Lazarus. The purpose of this guide is to document some of the specificĭifferences that are frequently encountered during the code conversion

Please see the Lazarus For Delphi Users guide for a description of some of the functional differences. and in someĪreas, FPC is enhanced and can be more demanding about correct syntax. ThereĪre a number of library call and convention differences. Have aspects in common with Delphi and Kylix, they are not clones.

This page is about how to port or convert existing Delphi or Kylix code to work with the Free PascalĬompiler and Lazarus IDE. this ia a highly Delphi-compatible and stable fallback package.its latest version git tag is 1.72, in the sdl2.pas it goes even up to version 1.80 hence starting with v2.0 for this fork is a senseful distinction.first official release of the PGD community fork of the Pascal-SDL-2-Headers.

updates of SDL2_Mixer, SDL2_Image, SDL2_TTF and some include files.

Moving the units to a new location may (1) raise difficulties in committing new changes if the branch was started before and (2) make updates of project research pathes necessary.

This release has all commits until the change of the project folder structure (see PR #27).

(done) shift all units into unit folder (see PR #27).

(done) replace data types by c data types (see PR #29).

be up-to-date with at least version 2.0.14 of the SDL2 library.

The version tag (see tags) refers to the version of this translation package SDL2 for Pascal, not the SDL2 library. Have a look at our Translation Cheat Sheet for reference. If an identifier or a function declaration is gone, mark them as deprecated. Hint: Use TSDL_Bool to translate SDL_bool. The original code) instead of UInt32, Cardinal, LongWord or DWord.Įxception: Replace *char by PAnsiChar! (see issue #26) (see issue #67)Įxample: Use cuint32 (if Uint32 is used in For Delphi we have a temporary solution provided. Note: For FPC you need to add the unit ctypes to use these Cĭata types. Use C data types like cuint8, cuint16, cuint32, cint8, cint16,Ĭint32, cfloat and so on if native C data types are used in the In Pascal function SDL_HasEvent(type_: TSDL_EventType). Names corresponding to reserved key words are kept and an underscore is added.Įx.: type in C function SDL_HasEvent(Uint32 type) changes into type_ Names of C defines (constants) and function parameters shall not be modified or 'pascalified'Įx: SDL_INIT_VIDEO does not change into SDLInitVideo. To discuss or extend these guidelines, use the issue tracker.

It easier to find certain code parts in the C headers/Pascal includes. These guidelines aim to have better consistency in this community project and make The main principle is to stay as tight as possible at the names in the C headers.

(Continously) Adapt comments to PasDoc format.

(Continously) improve Delphi-compatibility (and even more important, DO NOT break it).

See part Enums on the Cheat sheet for reference.

(Continously atm.) Translate integer aliases into typed enums.

(Continously) Update files by new SDL2 functions and types which are present in more recent SDL2 versions.

Please use the GitHub issue tracker for bug reports. If you have any contributions or bugfixes, feel free to drop a pull request or send in a patch. Units for the other SDL2 libraries are also provided: Use the sdl2 unit for the main SDL2 library (should be always needed).

just copying & pasting the units into the same directory as your main source code.

(FPC) using the -FuXXX command-line argument to the compiler.

(FPC) using the directive in your source code.

Simply add the units to your include path. This repository is a community-maintained fork of the Pascal-SDL-2-Headers repo.
