Go SourceGraph LSP Configuration
The details below describe how to install and configure the Go language server found
here.
NOTE: This installation process assumes Go has been installed on the machine.
Installing the Language Server
To install the language server run the following command:
go get github.com/sourcegraph/go-langserver
With the software installed test the installation by running go-langserver.exe --help at the command line prompt, which should result in the following output:
Usage of go-langserver.exe:
-addr string
server listen address (tcp) (default ":4389")
-freeosmemory
aggressively free memory back to the OS (default true)
-func-snippet-enabled
enable argument snippets on func completion. Can be overridden by InitializationOptions. (default true)
-gocodecompletion
enable completion (extra memory burden). Can be overridden by InitializationOptions.
-logfile string
also log to this file (in addition to stderr)
-maxparallelism int
use at max N parallel goroutines to fulfill requests. Can be overridden by InitializationOptions.
-mode string
communication mode (stdio|tcp) (default "stdio")
-pprof string
start a pprof http server (https://golang.org/pkg/net/http/pprof/)
-trace
print all requests and responses
-usebinarypkgcache
use $GOPATH/pkg binary .a files (improves performance). Can be overridden by InitializationOptions. (default true)
-version
print version and exit
If that output is not produced check the installation and also check to make sure the executuble installation folder has
been added to the system PATH environment variable.
Configuration
Start Zeus and use the
Options, Document Types menu to edit the Go document type and in the
Language Server panel apply the following configuration settings:
Program Type: Executable
Program: go-langserver.exe
Arguments: -mode=stdio
-trace
-gocodecompletion
NOTE: The executable directory option was omitted because it was assumed the executable folder is found in the system PATH environment variable.
Using the Language Server
To test the configuration create a simple test.go file and fire off an auto-complete request:
If the auto complete does not fire make sure the GOPATH is correctly configured and the test.go file folder location is in that path.
