This project defines a snap package for DCD, an auto-complete program for the D programming language. It is an 'external' snap, meaning that it downloads and builds the source from the official DCD git repo. For more information on DCD, see: https://github.com/dlang-community/DCD

The D programming language is a systems programming language with C-like syntax and static typing. It combines efficiency, control and modelling power with safety and programmer productivity. For more information on the D language, see: https://dlang.org/

Snap packages are designed to provide secure, containerized applications that are appropriately sandboxed away from the rest of the system they are running on. For more information on snap packages, see: http://snapcraft.io/

On Ubuntu 16.04 or higher with snapcraft installed (sudo apt install snapcraft):

git clone https://github.com/dlang-snaps/dcd.snap.git
cd dcd.snap
snapcraft

To ensure a clean build, install lxd (sudo apt install lxd), configure its network settings, and then:

snapcraft cleanbuild

DCD has been packaged as a classic snap, so installing it requires the --classic flag to be used in order to grant the necessary confinement permissions. Self-built snaps are unsigned and therefore also require the --dangerous flag in order to install them:

sudo snap install --classic --dangerous dcd_VERSION_amd64.snap

replacing VERSION as appropriate.

For more information on classic confinement, see: https://insights.ubuntu.com/2017/01/09/how-to-snap-introducing-classic-confinement/

To make the DCD server work properly, you must manually specify the import directories paths for D module imports, this snap does not do this automatically to allow the user to use dmd with any druntime + phobos configuration.

If you simply want to configure DCD to work with our DMD package (snapcraft.io/dmd) you just need to run this command which will enable the import paths of the DMD snap package in the current user:

echo -e "/snap/dmd/current/import/druntime\n/snap/dmd/current/import/phobos" > ~/.config/dcd/dcd.conf

For other dmd, druntime and phobos providers, consult their documentation to find out their import path.
