- build and test D from git
- build older versions of D
- build D plus forks and pending pull requests
- bisect D's history to find where regressions are introduced (or bugs fixed)
Digger has a simple command-line interface, as well as a web interface for customizing your custom D build.
On POSIX, Digger needs git, g++, binutils and make. gcc-multilib and g++-multilib or equivalent are required for targeting x86 on x86_64 systems.
On Windows, Digger will download and unpack everything it needs (Git, DMC, DMD, 7-Zip, WiX, VS2013 and Windows SDK components).
The easiest way to obtain and run Digger is through Dub. As Dub is included with DMD, simply run:
$ dub fetch digger $ dub run digger -- ...args...
You can find binaries on the GitHub releases page.
# build latest master branch commit $ digger build # build a specific D version $ digger build v2.064.2 # build for x86-64 $ digger build --model=64 v2.064.2 # build commit from a point in time $ digger build "@ 3 weeks ago" # build latest 2.065 (release) branch commit $ digger build 2.065 # build specified branch from a point in time $ digger build "2.065 @ 3 weeks ago" # build with added pull request $ digger build "master + dmd#123" # build with added GitHub fork branch $ digger build "master + Username/dmd/awesome-feature" # build with reverted commit $ digger build "master + -dmd/0123456789abcdef0123456789abcdef01234567" # build with reverted pull request $ digger build "master + -dmd#123"
Hacking on D
# check out git master (or some other version) $ digger checkout # build / incrementally rebuild current checkout $ digger rebuild # run tests $ digger test
digger with no arguments for detailed usage help.
Digger does not build all D components - only those that change frequently and depend on one another. You can get a full package by upgrading an installation of a stable DMD release with Digger's build result:
# upgrade the DMD in your PATH with Digger's result $ digger install
You can undo this at any time by running:
$ digger uninstall
Successive installs will not clobber the backups created by the first
digger install invocation,
digger uninstall will revert to the state from before you first ran
You can also simultaneously install 32-bit and 64-bit versions of Phobos by first building and installing a 32-bit DMD,
then a 64-bit DMD (
digger uninstall will revert both actions.
To upgrade a system install of DMD on POSIX, simply run
digger install as root, e.g.
sudo digger install.
digger install should be compatible with DVM or any other DMD installation.
Installation and uninstallation are designed with safety in mind.
When installing, Digger will provide detailed information and ask for confirmation before making any changes
(you can use the
--yes switches to suppress the prompt).
Uninstallation will refuse to remove files if they were modified since they were installed,
to prevent accidentally clobbering user work (you can use
--force to override this).
To bisect D's history to find which pull request introduced a bug, first copy
bisect.ini, adjust as instructed by the comments, then run:
$ digger bisect path/to/bisect.ini
digger-web to start the web interface, which allows interactively customizing a D version to build.
If you built
digger-web from source, you also need to build
You can optionally configure a few settings using a configuration file.
To do so, copy
digger.ini and adjust as instructed by the comments.
$ git clone --recursive https://github.com/CyberShadow/Digger $ cd Digger $ rdmd --build-only digger $ rdmd --build-only digger-web
If you get a link error, you may need to add
-debug due to a DMD bug.
A dub definition is also included.
On Windows, you may see:
Warning 2: File Not Found version.lib
This is a benign warning.
The code which builds D and manages the git repository is located in the ae library
ae.sys.d package), so as to be reusable.
Currently, the bulk of the code is in
The build requirements are fulfilled by the
Digger is the frontend to the above library code, implementing configuration, bisecting, etc.
Module list is as follows:
repo- customized D repository management, revision parsing
bisect- history bisection
custom- custom build management
digger- entry point and command-line UI
digger-web- web interface, works by launching
common- helpers shared by
Digger should work fine under Wine. For 64-bit builds, you must first run
Digger cannot do this automatically as this must be done from outside Wine.
