LSP compliance: 3.14
This is still a work in progress; there might still be bugs and crashes
DLS implements the server side of the Language Server Protocol (LSP) for the D programming language. It doesn't do much itself (yet), and rather uses already available components, and provides an interface to work with the LSP. Current features include:
- Code completion
- Going to symbol definition
- Finding references
- Symbol renaming
- Error checking
- Code formatting (document, range and on-type)
- Symbol listing (current document and workspace-wide)
- Symbol highlighting
- Documentation on hover
- Random, frustrating crashes
Packages used (the stuff doing the actual hard work):
If you are using VSCode, Visual Studio or Atom, you can skip this step and install the corresponding extension.
Simply run:
dub fetch dls
dub run dls:bootstrap
to install to download and install the latest binary release. The second command will output the executable's path. DLS will automatically update itself whenever a new version is out.
- Visual Studio Code: install the extension
- Visual Studio: install the extension
- Atom: install the package
- Sublime Text (using tomv654's LSP client):
{ "clients": { "dls": { "command": ["<PATH TO DLS EXECUTABLE>"], "enabled": true, "languageId": "d", "scopes": ["source.d"], "syntaxes": ["Packages/D/D.sublime-syntax"] } } }
- Vim/Neovim (using autozimu's LanguageClient-neovim):
let g:LanguageClient_serverCommands = { \ 'd': ['<PATH TO DLS EXECUTABLE>'] \ }
- Emacs (using d-mode and lsp-mode):
(require 'lsp) (add-hook 'd-mode-hook #'lsp) (lsp-register-client (make-lsp-client :new-connection (lsp-stdio-connection '("<PATH TO DLS EXECUTABLE>")) :major-modes '(d-mode) :server-id 'dls))
If it's not working with your editor of choice, submit a new issue !
DLS is usable using FreeBSD's Linux binary compatibility system (tested on FreeBSD 12.0-RELEASE). The main steps to enable Linux binary compatibility are:
- Adding
enable_linux="YES"
to/etc/rc.conf
- Running
kldload linux64
- Running
pkg install emulators/linux_base-c7
(oremulators/linux_base-c6
) - Running
pkg install ftp/linux-c7-curl
(orftp/linux-c6-curl
) - Adding the following lines to
/etc/fstab
:linprocfs /compat/linux/proc linprocfs rw 0 0 linsysfs /compat/linux/sys linsysfs rw 0 0 tmpfs /compat/linux/dev/shm tmpfs rw,mode=1777 0 0
- Running:
mount /compat/linux/proc mount /compat/linux/sys mount /compat/linux/dev/shm
More detailed/up-to-date information can be found in the FreeBSD documentation.
Some command line options exist to control the behavior of DLS:
--stdio
: use standard input and output streams for communication (default behavior)--socket=<PORT>
or--tcp=<PORT>
: use a socket to connect on the specified port for communication--version
: show version information--help
: show full list of command line options--init.*
: specify an initialization option
All these keys should be formatted as d.dls.[section].[key]
(e.g. d.dls.format.endOfLine
).

DLS supports a few custom initialization options in the InitializeParams.initializationOptions
object sent with the initialize
request:
interface InitializationOptions: {
autoUpdate?: boolean = true; // Enable auto-updating
preReleaseBuilds?: boolean = false; // Enable pre-release updates
safeMode?: boolean = false; // Disable processing multiple requests in parallel
catchErrors?: boolean = false; // Catch and ignore errors (WARNING: UNSAFE)
logFile?: string = ""; // Path to a file to log DLS operations
capabilities?: {
hover?: boolean = true; // Enable hover
completion?: boolean = true; // Enable completion
definition?: boolean = true; // Enable go-to-definition
typeDefinition?: boolean = true; // Enable go-to-type-definition
references?: boolean = true; // Enable references search
documentHighlight?: boolean = true; // Enable symbol highlighting
documentSymbol?: boolean = true; // Enable document symbol search
workspaceSymbol?: boolean = true; // Enable workspace symbol search
codeAction?: boolean = true; // Enable code actions
documentFormatting?: boolean = true; // Enable formatting
documentRangeFormatting?: boolean = true; // Enable range formatting
documentOnTypeFormatting?: boolean = true; // Enable on type formatting
rename?: boolean = true; // Enable renaming
},
symbol?: {
autoImports?: boolean = true; // Automatically import projects and their dependencies
}
}
Every initialization option can be toggled via a command line option.
Example: ./dls --init.logFile=path/to/file.log
.
Initialization options set suring the initialization phase will override ones set with command line options.
The server may delegate a few operations to the client-side extension depending on the language client's capabilities. The client should watch these files for the server to work properly:
dub.selections.json
dub.json
dub.sdl
.gitmodules
*.ini
If the client supports dynamic registration of the workspace/didChangeWatchedFiles
method, then the server will automatically register file watching.
If the client doesn't support dynamic registration however, the client-side extension will need to manually do it.
The server needs to know at least when dub.selections.json
files change to properly provide completion support.
If dub.json
and dub.sdl
are also watched, dub.selections.json
can be regenerated on demand.
Watching *.ini
allows DLS to monitor D-Scanner config files, even if the name is changed in the config and isn't dscanner.ini
.
Since the LSP defines messages with methods starting in $/
to be implementation dependant, DLS uses $/dls
as a prefix for custom messages.
Message | Type | Parameters | Description |
---|---|---|---|
$/dls/upgradeDls/didStart |
Notification | TranslationParams |
Sent when the upgrade process starts |
$/dls/upgradeDls/didStop |
Notification | null |
Sent when the upgrade process stops |
$/dls/upgradeDls/didChangeTotalSize |
Notification | DlsUpgradeSizeParams |
Sent during the download, with the total size of the upgrade download |
$/dls/upgradeDls/didChangeCurrentSize |
Notification | DlsUpgradeSizeParams |
Sent during the download, with the current size of the upgrade download |
$/dls/upgradeDls/didExtract |
Notification | TranslationParams |
Sent when the download is finished and the contents are written on the disk |
$/dls/upgradeSelections/didStart |
Notification | TranslationParams |
Sent when DLS starts upgrading dub.selections.json |
$/dls/upgradeSelections/didStop |
Notification | null |
Sent when DLS has finished upgrading dub.selections.json |
interface TranslationParams {
tr: string;
}
interface DlsUpgradeSizeParams extends TranslationParams {
size: number;
}
The file i18n/data/translations.json
contains localization strings.
Adding new strings is straightforward, simply add new entries in the message
objects with the locale identifier as key and the translated string as value.
- Is it work on a new feature ? Then the
master
branch should be targeted. - Is it a fix ? Then the latest
release/v<MAJOR>.<MINOR>.x
branch should be targeted.
To run automated tests, run dub test --main-file=tests/main.d
