All major compilers are supported (DMD, GDC, and LDC). DUB is used for project management and building. It is typically available in system repositories as 'dub'. DMD is typically available in system repositories and on https://dlang.org/. GDC is typically available in system repositories as 'gdc', 'gdc-*', 'gcc-gdc', 'gcc*-gdc', 'gcc-d', or 'gcc-d-*'. For example, on Ubuntu 24.04, 'gdc-9' to 'gdc-14' are available. This project doesn't use 'gdmd', the dmd wrapper. LDC is typically available in system repositories as 'ldc', and is typically invoked using 'ldc2'. This project doesn't use 'ldmd2', the dmd wrapper. Minimum version should be a compiler with DMD front-end version 2.081 and later. Project successfully compiles on Ubuntu 16.04 using dmd-2.082.0, using the deb package from dlang.org. Compile a debug build: $ dub build Compile a release build using a specified compiler: $ dub build -b release --compiler=ldc2 // Makefile If DUB is unavailable, a Makefile is also available. Default target is 'release', meaning an optimized release will be created. Other targets include 'debug', 'debugv', 'native', 'debug-static', 'release-static', and 'native-static'. //////////////////////////////////////////////////////////////////////////////// // Debugging Since things might break, there are unit testing and logging facilities. Run unit tests (useful for new platforms): $ dub test Run unit tests with log traces to stderr: $ dub test --d-version=Trace Run a specific system integration test: $ dub test -b TYPE TYPE: input (terminal input), color (terminal colors), size (terminal size) The Makefile also accepts 'test', 'test-input', 'test-size', and 'test-size'. Environment variables: - DDHX_LOG=PATH - If set, enables logging debugging information into this file. - Version: Since 0.7 - DDHX_BACKEND=BACKEND - Forces BACKEND to be selected. - Version: Since 0.7 - Default: "piecev3" (since 0.9) - Backends: "piecev3" (>=0.9), "piecev2" (>=0.8), "piece" (>=0.7 <0.9) - DDHX_NO_INPLACE_SAVE - If set to 1, avoid the use of the newer "in-place" saving mechanic. - Version: Since 0.9 ******************************************************************************** * NOTICE * ******************************************************************************** This software is provided with NO WARRANTY as it is marked as EXPERIMENTAL. Major progress has been made since version 0.5! It should be good enough for regular use.
