digger 3.0.0-alpha-5

A tool to build D and bisect old D versions

To use this package, run the following command in your project's root directory:

Manual usage
Put the following dependency into your project's dependences section:

Digger Build Status AppVeyor

Digger can:

  • 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.

On Windows, Digger will download and unpack everything it needs (Git, DMC, DMD, 7-Zip, WiX, VS2013 and Windows SDK components).

Get Digger

You can find binaries on the GitHub releases page.

Command-line usage

Building D
# 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

Run 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, so digger uninstall will revert to the state from before you first ran digger install.

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 (--model=64). 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 --dry-run / --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.sample to bisect.ini, adjust as instructed by the comments, then run:

$ digger bisect path/to/bisect.ini

Web interface

Run 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 digger itself.


You can optionally configure a few settings using a configuration file. To do so, copy digger.ini.sample to 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 ae.sys.d.manager.

ae.sys.d.manager clones a meta-repository on BitBucket, which contains the major D components as submodules. The meta-repository is created and maintained by another program, D-dot-git.

The build requirements are fulfilled by the ae.sys.install package.


Digger is the frontend to the above library code, implementing configuration, bisecting, etc.

Module list is as follows:

  • config - configuration
  • repo - customized D repository management, revision parsing
  • bisect - history bisection
  • custom - custom build management
  • install - installation
  • digger - entry point and command-line UI
  • digger-web - web interface, works by launching digger sub-processes
  • common - helpers shared by digger and digger-web



Digger should work fine under Wine. For 64-bit builds, you must first run winetricks vcrun2013. Digger cannot do this automatically as this must be done from outside Wine.
