This article is part of the Getting Started Section. It describes how to run XPath/XQuery code from within the IntelliJ IDEA IDE. There are currently two XQuery plugins for IntelliJ IDEA on the market:

Contents

[edit] Preparations

The following steps apply to all operating systems and both plugins:

This section focuses on Reece H. Dunn's xquery-intellij-plugin.

[edit] Installation

After installing IntelliJ IDEA and BaseX, install the xquery-intellij-plugin by one of the following methods:

From the Start Screen

From the IntelliJ IDEA Menu

[edit] Conclusion

The plugin is very well maintained! It adds support for various XQuery Implementations to the IntelliJ IDEA (among them BaseX). It provides syntax highlighting for XQuery and XML and detects syntactical errors while you type offering a description for each error. Queries are executed using Run Configurations for which you can configure various query processors, e.g. BaseX.

The plugin contains some minor flaws regarding the static binding of BaseX namespaces. A few namespaces are marked as unknown in the code, however, query execution in the BaseX backend works fine in spite of them. Also, the IntelliJ Find Usages and Go To options did not work as expected in some cases, especially with regard to functions and across modules. The plugin does not yet include a code completion feature.

Note that the usage of functions from imported or declared namespaces that do not exist in the namespace might not be marked as unknown. To highlight invalid functions, you may enable the XPath and XQuery > XPST: XPath static errors > XPST0017: Undefined function inspection in the Editor > Inspections section.

[edit] XQuery Support Plugin

This section focuses on Grzegorz Ligas' XQuery Support plugin.

[edit] Installation

After installing IntelliJ IDEA and BaseX, install the XQuery Support plugin by one of the following methods:

From the Start Screen

From the IntelliJ IDEA Menu

[edit] Configuring The Processor

You can set up the plugin as a standalone processor or client.

[edit] Client

This assumes that you already have a BaseX database named factbook.

[edit] Conclusion

The plugin adds support for various XQuery Implementations to the IntelliJ IDEA (among them BaseX). It provides syntax highlighting for XQuery and XML and detects syntactical errors while you type offering a description for each error. Queries are executed using Run Configurations for which you can configure various query processors, e.g. BaseX. The plugin offers code completion for XQuery functions, integrated library modules, such as FunctX or the BaseX Module Library, and user-defined modules. IntelliJ’s Find Usages and Go To options seem to work fine for variables and functions, even across modules. Users can set XQuery-specific code style preferences.

This plugin also has a few minor drawbacks. If no path is specified, syntax highlighting marks user-defined modules as unknown, even if they reside in the designated BaseX module repository. However, the BaseX query processor, resolves them correctly during query execution. Error messages in the editor seem to be kept rather general and should me more specific. Parameter lists of code completion may be quite extensive and clog the screen. Leading tab space can be increased in user-defined steps, but neither decreased in single, nor user-defined steps.
