QLS is a language server for the Qore programming language.

QLS adheres to the Language Server Protocol, specifically to version 3.0 of the protocol. All communication is done via stdin/stdout.

QLS requires Qore 0.9.14+ and the astparser and json modules to be installed for all the functionality to work.

QLS supports the following LSP features:

• qore.logVerbosity Verbosity of QLS logging. From 0 to 2. [default=0]
• qore.appendToLog Boolean flag specifying whether to append to QLS log file or to overwrite it on each restart. [default=true]
