The {{Code|.basex}} * '''[[Configuration#Configuration FilesGlobal Options|configuration fileGlobal Options]] is parsed by every new local ''' are valid for all BaseX instanceinstances in the same JVM. It This is used to store particularly relevant if you are working with the client/server architecture.* '''Local options ''' (all remaining ones) are specific to disk:a client or session.
* Global Values of options can only be set via the configuration file are either ''strings'', ''numbers'' or system properties ''booleans''. Options are ''static'' and not bound to a single operation (see belowfor example, the next command).* With {{Version|7.6}} Various ways exist to access and later, local change options can also be specified in the configuration file after the {{Code|# Local Options}} comment.:
Various ways exist to access * The current value of an option can be requested with the {{Command|GET}} command. Local options can be changed via {{Command|SET}} (all global options, except for {{Option|DEBUG}}, can only be changed at startup time). If an option is of type ''boolean'', and change options:if no value is specified, its current value will be inverted.
* Initial values for options can also be specified via system properties, which can e.g. be passed on with the [http<pre class="brush://docs.oracle.com/javase/1.4.2/docs/tooldocs/windows/java.htmlperl">#options -D flag] on command line, or using [http://docsGeneral OptionsDEBUG = false.oracle.com/javase/6/docs/api/java/lang/System.html#setProperty(java.lang.String,%20java.lang.String) System.setProperty()] before creating a BaseX instance. The specified keys needs to be prefixed with {{Code|org.basex.}}. An example:
<pre class="brush:bash"># Local Optionsjava -Dorg.basex.CHOP=false -cp basex.jar org.basex.BaseX -c"get chop"CHOP: false
declare option db:chop 'java -Dorg.basex.CHOP=false';-cp basex.jar org.basex.BaseX -c"get chop"CHOP: false
<pre class="brush:xquery">(# db:chop false #) { parse-xml('<xml> hi </xml>') }</pre> * If using the Mac OS X packaged application then global options are implicitly changed by operations in the [[GUI]], the underlying commands will be listed in the [[GUI#Visualizations|Info View]].<br/><br/> =Global Options= This article is part of the [[Getting Started]] Section.It lists all database commands supported by BaseX.Commands can e.g. be executed from set within the [[Startup_Options#BaseX_Standalone|Command Line]],[[#Command Scripts|Scripts]], the [[Clients]], [[REST]], the input field in the [[GUI]]and other ways. If the GUI is used, all commands that are triggered by the GUI itselfwill show up in the [[GUI#Visualizations|Info View]].The [[User_Management|Permission]] fields indicate whichrights are required by a user to perform a command in plist file within the client/server architecture. =Basics= ==Command Scripts== Database commands in both the string and XML syntax can be placed in a text file and stored on disk. The default extension for BaseX command scripts is {{Code|.bxs}}. If Contents folder of the path to a command script is passed on to BaseX, it will automatically be recognized and evaluated as such. ==String Syntax== Multiple commands can be written in a single line and separated by semicolons, or stored as command script. Lines starting with <code>#</code> are interpreted as comments and are skippedapplication package. The following script creates a database, adds two documents to it and performs a queryFor example:
CREATE DB test<key>JVMOptions</key>ADD input.xml<array>ADD TO embedded.xml <rootstring>embedded-Dorg.basex.CHOP=false</rootstring># run queryXQUERY count(<//text())array>
==XML Syntax== The string syntax is limited when XML snippets need to be embedded in * In a command[[Web Application]],or when complex queries are to be specified. This is why database commands the default can also be specified adjusted in XML.Multiple commands can be enclosed by a the {{Code|<commands/>web.xml}} root elementfile as follows:
==Glob Syntax==* In XQuery, local options can be set via option declarations and [[XQuery Extensions#Pragmas|pragmas]].
Some commands support If options are changed by operations in the glob syntax to address more than one database or user. Question marks and asterisks can be used to match one or more characters[[GUI]], and commas can the underlying commands will be used to separate multiple patternslisted in the [[GUI#Visualizations|Info View]]. Some examples:<br/><br/>
* {{Code|AB?}} addresses all names with the characters {{Code|AB}} and one more character.* {{Code|*AB}} addresses all names ending with the characters {{Code|AB}}.* {{Code|X*,Y*,Z*}} addresses all names starting with the characters {{Code|X}}, {{Code|Y}}, or {{Code|Z}}. =Global Options=Valid Names== Both database and user names must follow the same naming constraints. Valid names may contain letters, numbers, underscores and dashes. Names must have at least one character; they also should not be longer than 128 characters, although this is not enforced. A regular expression matching valid names is <code>[-_a-zA-Z0-9]{1,128}</code>.
==Aliases==Global options are constants. They can only be set in the configuration file or via system properties (see above). One exception is the [[#debug|DEBUG]] option, which can also be changed at runtime by users with [[User Management|admin permissions]].
In all commands, the {{Code|DB}} keyword can be replaced by {{Code|DATABASE}}.==General Options==
