XML Language Server

I started this project when there was no XML Plugin available for VSCode. But now we have XML Plugin by RedHat available, so I recommend all to use that.
Do check em out: https://github.com/angelozerr/lsp4xml, https://github.com/redhat-developer/vscode-xml.
I will continue improving the current one, but not having the freedom to dedicate time on it may take a bit longer to finish it.

Language server for XML documents. It enables and LSP client (VScode, Sublime LSP, Eclipse Che) to leverage capabilities such as autocomplete, validation or documentation support for XML documents.

Refer to CONTRIBUTING.md for setting up development environment

What is language server?

Language server is the server part of Language Server Protocol (LSP).
As per official documentation,

The Language Server protocol is used between a tool (the client) and a language smartness provider (the server) to integrate features like auto complete, go to definition, find all references and alike into the tool.

Why XML?

We use XML documents, configs extensively for our day to day work, and simple config typo of elements or attributes breaks our head for hours. Intellij was already supporting features for XML such as validation, autocomplete, documentation (using annotations from xsd), but text editors like vscode or sublime doesn't have support for XML. It's an attempt to make editors smart for XML documents.

Why Java?

Currently the implementation of language server for XML is done in Java. I couldn't find a mature and apt library for XML manipulations in other languages. Becuase of the nature of Java previous to Java 9 the users of this server (language client) needs to have java installed in their system.

Build

• Requirements:
  • Java 8
  • Maven 3.5+

mvn clean package # To generate jar file locally
mvn clean install # To install artifact in local repository

For Docker Fans

docker run -it --rm --name xml-language-server -v $(pwd):/usr/src/mymaven -w /usr/src/mymaven maven:3.6.0-jdk-8-alpine mvn clean install

Don't forget to replace $(pwd) with absolute path of the project.
Also if you are on windows make sure, you have give docker permission to access/mount volumes.
