Changes

* The {{Code|.basex}} [[Configuration#Configuration Files|configuration file]] is parsed by every new local BaseX instance. It contains all global options. Local options can be specified at the end of the file after the {{Code|Local Options}} comment:

# General Options

DEBUG = false

# Local Options

CATALOG = etc/w3-catalog.xml

* Initial values for global options can also be specified via system properties, which can be passed on with the [https://docs.oracle.com/en/java/javase/11/tools/java.html -D flag] on the command line, or with [https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/System.html#setProperty(java.lang.String,java.lang.String) System.setProperty()] before creating a BaseX instance. The specified keys need to be prefixed with {{Code|org.basex.}}. An example:

java -Dorg.basex.CATALOG=etc/w3-catalog.xml -cp basex.jar org.basex.BaseX -c"SHOW OPTIONS catalog"

CATALOG: etc/w3-catalog.xml

* If the Mac OS X packaged application is used, global options can be set within the Info.plist file within the Contents folder of the application package. For example:

<key>JVMOptions</key>

<array>

<string>-Dorg.basex.CATALOG=etc/w3-catalog.xml</string>

</array>

* In a [[Web Application]], the default can be adjusted in the {{Code|web.xml}} file as follows:

<context-param>

<param-name>org.basex.catalog</param-name>

<param-value>etc/w3-catalog.xml</param-value>

</context-param>

* In XQuery, local options can be set via option declarations and [[XQuery Extensions#Pragmas|pragmas]].

===IGNORECERT===

{| width='100%'

|- valign="top"

| '''Summary'''

* The listener for stopping the web server will only be started if the specified value is greater than {{Code|0}}.

* The option is ignored if BaseX is used as a [[Web Application]] or started via [[Web Application#Maven|Maven]].

===STRIPWS===

{| width='100%'

* If the option is enabled, whitespaces of an element and its descendants can locally be preserved with the <code>xml:space="preserve"</code> attribute:

<xml>

<title>

<text xml:space="preserve">To <b>be</b>, or not to <b>be</b>, that is the question.</text>

</xml>

If whitespaces are stripped, <code>indent=yes</code> can be assigned to the {{Option|SERIALIZER}} option to get properly indented XML output.<br/>

See [[BaseX_10#Whitespaces|BaseX 10: Whitespaces]] for more information on whitespace handling.

===CATALOG===

{| width='100%'

===BINDINGS===

{| width='100%'

* Commas in values must be duplicated.

* Variables may optionally be introduced with a leading dollar sign.

This option can also be used on [[Command-Line Options#BaseX Standalone|command line]] with the flag <code>-b</code>.

|- valign="top"

* <code>{URI}a=x</code> &nbsp; binds the value {{Code|x}} to the variable $a with the namespace {{Code|URI}}.

* In the following [[Commands#Command_Scripts| Command Script]], the value {{Code|hello world!}} is bound to the variable {{Code|$GREETING}}:

SET BINDINGS GREETING="hello world!"

XQUERY declare variable $GREETING external; $GREETING

|}

| '''Summary'''

|When creating new nodes in XQuery via [https://www.w3.org/TR/xquery-31/#id-constructors Node Constructors], copies of all enclosed nodes are created, and the copied nodes get new node identities. As a result, the following query yields <code>false</code>:

let $a := <a/>

let $b := <b>{ $a }</b>

return $b/a is $a

This step can be expensive and memory consuming. If the option is disabled, child nodes will only be linked to the new parent nodes, and the upper query returns <code>true</code>.<br/>The option should be used carefully as it changes the semantics of XQuery. It should preferably be used in [[XQuery Extensions#Database Pragmas|Pragmas]].
