Requirements

For running the binary version: • Windows, macOS, or Linux, on a x86_64 CPU • ~~We do not currently support running on Linux installations without libc present~~ See #1016 • Java is not required for this version • The binary is automatically downloaded by vscode-xml if it is needed, with no additional action required on the part of the user.

For running the Java version (required if you want to run extensions to the base XML features): • Java JDK (or JRE) 11 or more recent • Ensure Java path is set in either: • xml.java.home in VSCode preferences • java.home in VSCode preferences • Environment variable JAVA_HOME or JDK_HOME • Note: The path should end at the parent folder that contains the bin folder. Example Path: /usr/lib/jvm/jre-11 if bin exists at /usr/lib/jvm/jre-11/bin. • Note: If the path is not set, the extension will attempt to find the path to the JDK or JRE.

See how to set java home for more information how this extension searches for Java.

Supported VS Code settings

The following settings are supported:

• xml.java.home: Specifies the folder path to the JDK (11 or more recent) used to launch the XML Language Server if the Java server is being run. If not set, falls back to either the java.home preference or the JAVA_HOME or JDK_HOME environment variables. • xml.server.vmargs: Specifies extra VM arguments used to launch the XML Language Server. Eg. use -Xmx1G -XX:+UseG1GC -XX:+UseStringDeduplication to bypass class verification, increase the heap size to 1GB and enable String deduplication with the G1 Garbage collector. • xml.server.workDir: Set a custom folder path for cached XML Schemas. An absolute path is expected, although the ~ prefix (for the user home directory) is supported. Default is ~/.lemminx. • xml.server.preferBinary: If this setting is enabled, a binary version of the server will be launched even if Java is installed. • xml.server.binary.path: Specify the path of a custom binary version of the XML server to use. A binary will be downloaded if this is not set. • xml.server.binary.args: Command line arguments to supply to the binary server when the binary server is being used. Takes into effect after relaunching VSCode. Please refer to this website for the available options. For example, you can increase the maximum memory that the server can use to 1 GB by adding -Xmx1g • xml.server.silenceExtensionWarning: If this setting is enabled, do not warn about launching the binary server when there are extensions to the XML language server installed. • xml.server.binary.trustedHashes: List of the SHA256 hashes of trusted copies of the lemminx (XML language server) binary. • xml.trace.server: Trace the communication between VS Code and the XML language server in the Output view. Default is off. • xml.logs.client: Enable/disable logging to the Output view. Default is true. • xml.catalogs: Register XML catalog files. • xml.downloadExternalResources.enabled: Download external resources like referenced DTD, XSD. Default is true. • xml.fileAssociations: Allows XML schemas/ DTD to be associated to file name patterns. • xml.foldings.includeClosingTagInFold: Minimize the closing tag after folding. Default is false. • xml.preferences.quoteStyle: Preferred quote style to use for completion: single quotes, double quotes. Default is double. • xml.autoCloseTags.enabled : Enable/disable autoclosing of XML tags. Default is true. IMPORTANT: The following settings must be turned of for this to work: editor.autoClosingTags, editor.autoClosingBrackets. • xml.codeLens.enabled: Enable/disable XML CodeLens. Default is false. • xml.preferences.showSchemaDocumentationType: Specifies the source of the XML schema documentation displayed on hover and completion. Default is all. • xml.validation.enabled: Enable/disable all validation. Default is true. • xml.validation.namespaces.enabled: Enable/disable namespaces validation. Default is always.
