Try DlangIDE

You can use DUB utility and DMD compiler to download, build and run recent version of DlangIDE from GIT repository.

Pre-requisites: install DMD from https://dlang.org/download.html. In recent DMD packages, DUB utility is included.

Now you can fetch, build and run DlangIDE:

dub fetch dlangide
dub run --build=release dlangide

OSX build notes

On OSX you will need to install libSDL2, which is used as a default backend.

E.g. use homebrew or some other package manager to install it.

brew install sdl2

For troubleshooting of screen DPI detection (e.g. if everything is small on Retina display), you can choose DPI manually in menu Edit / Preferences / Interface : Override screen DPI. (This issue will be fixed soon).

Linux build notes

On Linux will need to install libSDL2, which is used as a default backend.

If it's not yet installed, install it in order to run DlangIDE.

For debian/ubuntu use:

sudo apt-get install libsdl2-dev

For RPM based distributions:

sudo yum install SDL2-devel

Windows build notes

Pre-built win32 binaries can be found in releases section.

As well, you can build it yourself.

Recent builds with dmd under windows have issues with crash in OPTILINK linker from DMD.

Workaround: add --arch=x86mscoff or --arch=x8664 to DUB commandline

Build 32bit version using microsoft linker and COFF object and library file format:

dub run --build=release --arch=x86_mscoff dlangide

Build 64bit version using microsoft linker:

dub run --build=release --arch=x86_64 dlangide

Note: unlike default --arch=x86, both x86mscoff and x8664 have a dependency on linker from Visual Studio C++ compiler toolchain.

Build tools

DlangIDE uses DUB as build tool, and its dub.json or dub.sdl as project file format. You can select DMD, LDC or GDC compiler toolchain.

DCD integration

Symbol lookup and autocompletion is using DCD (D completion daemon).

Hans-Albert Maritz (Freakazo) implementated DCD integration using DCD client/server.

Keywan Ghadami improved it to use DCD as a library.

Now DCD is embedded into DlangIDE, and no separate executables are needed.

Importing of existing project

DlangIDE supports only DUB project format.

To import existing DUB project, use menu item "File" / "Open project or workspace" and select dub.json or dub.sdl of your project to import.

Debugger support

  • Windows: use mago-mi debugger (https://github.com/buggins/dlangide/blob/master/libs/windows/x86/mago-mi.exe) or GDB
  • Linux: use GDB or lldb-mi debugger
  • OSX: use GDB or LLDBMI2 debugger

Building DlangIDE

Build and run with DUB:

git clone https://github.com/buggins/dlangide.git
cd dlangide
dub run

If you see build errors, try to upgrade dependencies:

dub clean-caches

dub upgrade --force-remove dub build --force

Needs DMD 2.066.1 or newer to build.

HINT: Try to open sample project Tetris, from workspaces/tetris with DlangIDE.

To develop in VisualD together with DlangUI, put this project on the same level as dlangui repository, and its dependencies.

Keyboard shortcut settings

Keyboard shortcuts settings support is added.

For linux and macos settings are placed in file


For Windows, in directory like


If no such file exists, it's being created on DlangIDE start, filling with default values to simplify configuration.

Just edit its content to redefine some key bindings.

File format is simple and intuitive. Example:

    "EditorActions.Copy": "Ctrl+C",
    "EditorActions.Paste": "Ctrl+V",
    "EditorActions.Cut": "Ctrl+X",
    "EditorActions.Undo": "Ctrl+Z",
    "EditorActions.Redo": [
    "EditorActions.Indent": [
    "EditorActions.Unindent": [
    "EditorActions.ToggleLineComment": "Ctrl+/",
    "EditorActions.ToggleBlockComment": "Ctrl+Shift+/"

Development environment setup

Howto hack DlangIDE.

For Windows, install MS Visual Studio (e.g. Community 2013) + VisualD plugin

Install GIT, DUB, DMD.

For Linux and OSX, install MonoDevelop + Mono-D plugin.

For Linux / OSX, additionally install libSDL2 and X11 development packages.

Create some folder to place sources, e.g. ~/src/d/

Clone DlangUI and DlangIDE repositories into source folder

git clone --recursive https://github.com/buggins/dlangui.git
git clone --recursive https://github.com/buggins/dlangide.git

Windows: open solution file with Visual-D


Linux: open solution file with Mono-D


OSX: open solution file with Mono-D


Choose dlangide as startup project.

Workspace include path setting

Now you can set dmd includes paths (for correct work with DCD) in workspace settings file (newworkspace.dlangidews) <pre> example: {

"name" : "newworkspace",
"description" : null,
"projects" : {
        "newproject" : "newproject/dub.json"<br>
"includePath" : [

} </pre>
