This section focuses on Reece H. Dunn's [https://plugins.jetbrains.com/plugin/8612-xquery-intellij-plugin xquery-intellij-plugin]. ==Installation== After installing IntelliJ IDEA and BaseX, install the xquery-intellij-plugin by one of the following methods: '''From the Start Screen''' [[File:intellij-startbildschirm.png]] * Start IntelliJ IDEA and select ''Configure''→''Plugins''.* In the Plugins window, select the tab ''Marketplace''.* Type "XQuery" into the ''Search plugins in marketplace'' field.* Click the ''Install'' button below ''xquery-intellij-plugin''.* You will be prompted to restart IDEA to load the new plugin. '''From the IntelliJ IDEA Menu'''* Select ''Settings'' (Windows)/''Preferences'' (macOS) in the ''IntelliJ IDEA'' menu.* In the Settings/Preferences window, select ''Plugins''.* In the Plugins window, select the tab ''Marketplace''.* Type "XQuery" into the ''Search plugins in marketplace'' field.* Click the ''Install'' button below ''xquery-intellij-plugin'' plugin.* You will be prompted to restart IDEA to load the new plugin. ==Configuring The Processor==* Start IntelliJ IDEA and navigate to ''Settings'' (Windows)/''Preferences'' (macOS) either using the ''Configure'' button from the start screen or the ''IntelliJ IDEA'' menu.* In the Settings/Preferences window, expand the ''Languages & Frameworks'' item and select ''XQuery''.* Make the choices for your system from the dropdown boxes, e.g.:** <code>Implementation = BaseX</code>** <code>Implementation version = BaseX 9.1</code>** <code>Default XQuery version = XQuery 3.1</code>** <code>Dialect for XQuery 3.0 = BaseX</code>** <code>Dialect for XQuery 3.1 = BaseX</code>[[File:Intellij-xquery-settings-2.png‎]]* Click ''Apply'' to store your XQuery settings and then ''OK'' to exit the dialog. ==Querying Your Data== '''Create a New Project'''* To create a new project choose the ''Create new project'' option from the start screen or select ''New''→''Project...'' from the ''File'' menu.* In the ''New Project'' dialog, choose ''Empty Project'' from the left-hand column and click the ''Next'' button.* Enter a name and location for your project and click on the ''Finish'' button. '''Customize the XQuery Module'''* Click the ''Add Configuration'' button below the IntelliJ IDEA menu bar.[[File:Intellij-add-configuration.png]]* In the ''Run/Debug Configurations'' dialog, expand the Templates list and choose the ''XQuery'' entry.* Click on the three dots {{Code|...}} next to the ''Query Processor'' dropdown box.* In the ''Manage Query Processors'' dialog, click on the {{Code|+}} button.* In the ''New Query Processor Instance'' dialog, set the following preferences:** <code>Name = BaseX</code> (optional; if you leave this field blank, <code>[Implementation] [Version]</code> will be used as name)** <code>Implementation = BaseX</code> (should be preset!)** <code>JAR File = BaseX.jar</code> (name and location of the JAR file may differ depending on your BaseX distribution and version)** <code>Hostname = localhost</code>** <code>Database port = 1984</code>** <code>Username = admin</code>** <code>Password = admin</code>** If you tick the check box ''Create a standalone instance'', the fields ''Hostname'', ''Database port'', ''Username'', and ''Password'' remain empty.[[File:Intellij-new-query-processor.png]]* Click ''OK'' to exit the ''New Query Processor Instance'' dialog.* In the ''Manage Query Processors'' dialog, now choose the "BaseX [''Version''] (BaseX)" entry and click ''OK''.* The ''Query Processor'' dropdown box in the ''Run/Debug Configurations'' dialog should now also display "BaseX [''Version''] (BaseX)". If not, select it from the dropdown box.* Click ''Apply'' and then ''OK'' to close the ''Run/Debug Configurations'' dialog. '''Create a Query File'''* In the project view, create a new XQuery file, either by right-clicking on the project name and choosing ''New''→''File'' or by selecting ''New''→''File'' from the File menu. Enter a file name and click ''OK''.* Type in your query, e.g. <code>db:open("factbook")</code>, and save your file. '''Create a New Configuration'''* Click on the ''Add Configuration'' button once again.* In the ''Run/Debug Configurations'' dialog, click the {{Code|+}} button to create a new configuration based on a template.* Choose the "XQuery" template you configured earlier.* Enter a name, e.g. "BaseX", into the ''Name'' field.* The query processor should be preset to "BaseX [''Version''] (BaseX)".* In the ''Run the query from'' area, either enter the path to your query file into the ''Local file'' field to limit the run configuration to that query or choose the ''Active editor file'' option to make the configuration run the script that is currently opened in the IntelliJ editor panel.[[File:Intellij-xquery-configuration.png]]* Click ''Apply'' and then ''OK'' to close the ''Run/Debug Configurations'' dialog.* Now, the configuration should be set and the green ''Run'' button should be available below the IntelliJ IDEA menu bar.[[File:Intellij-run-button.png]] '''Execute Your Query'''* If the configuration does not run as a standalone instance, make sure that BaseX is up and running.* Click the ''Run'' button to execute your query. ==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. =XQuery Support Plugin= This section focuses on Grzegorz Ligas' [https://plugins.jetbrains.com/plugin/97577262-xquery-support--marklogic-debugger XQuery Support plugin].

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.
