/* UnrealPluginLanguage (UPL) is a simple XML-based language for manipulating XML and returning
* strings. It contains an <init> section which is evaluated once per architecture before any
* other sections. The state is maintained and carried forward to the next section evaluated
* so the order the sections are executed matters.
*
* While UPL is a general system for modifying and quering XML it is specifically used to allow
* plug-ins to effect the global configuration of the package that they are a part of. For
* example, this allows a plug-in to modify an Android's APK AndroidManfiest.xml file or an
* IOS IPA's plist file. UBT will also query a plug-in's UPL xml file for strings to be included
* in files that must be common to the package such as some .java files on Android.
*
* If you need to see the instructions executed in your plugin context add the following to
* enable tracing:
*
* <trace enable="true"/>
*
* After this instuction all the nodes actually executed in your context will be written to the
* log until you do a <trace enable="false"/>. You can also get a dump of all the variables in
* your context with this command:
*
* <dumpvars/>
*
* Bool, Int, and String variable types are supported. Any attribute may reference a variable
* and will be replaced with the string equivalent before evaluation using this syntax:
*
* $B(name) = boolean variable "name"'s value
* $I(name) = integer variable "name"'s value
* $S(name) = string variable "name"'s value
* $E(name) = element variable "name"'s value
*
* The following variables are initialized automatically:
*
* $S(Output) = the output returned for evaluating the section (initialized to Input)
* $S(Architecture) = target architecture (armeabi-armv7a, arm64-v8a, x86, x86_64)
* $S(PluginDir) = directory the XML file was loaded from
* $S(EngineDir) = engine directory
* $S(BuildDir) = project's platform appropriate build directory (within the Intermediate folder)
* $S(Configuration) = configuration type (Debug, DebugGame, Development, Test, Shipping)
* $B(Distribution) = true if distribution build
*
* Note: with the exception of the above variables, all are in the context of the plugin to
* prevent namespace collision; trying to set a new value to any of the above, with the
* exception of Output, will only affect the current context.
*
* The following nodes allow manipulation of variables:
*
* <setBool result="" value=""/>
* <setInt result="" value=""/>
* <setString result="" value=""/>
* <setElement result="" value=""/>
* <setElement result="" value="" text=""/>
* <setElement result="" xml=""/>
*
* <setElement> with value creates an empty XML element with the tag set to value.
* <setElement> with value and text creates an XML element with tag set to value of unparsed text.
* <setElement> with xml will parse the XML provided. Remember to escape any special characters!
*
* Variables may also be set from a property in an ini file:
*
* <setBoolFromProperty result="" ini="" section="" property="" default=""/>
* <setBoolFromPropertyContains result="" ini="" section="" property="" default="" contains=""/>
* <setIntFromProperty result="" ini="" section="" property="" default=""/>
* <setStringFromProperty result="" ini="" section="" property="" default=""/>
*
* Strings may also be set from an environment variable using the <setStringFromEnvVar> node.
* The environment variable must be specified as the 'value' attribute and wrapped in a pair
* of '%' characters.
*
* <setStringFromEnvVar result="" value=""/>
*
* You can also check if a specific environment variable is defined (again, wrapped in '%' characters):
*
* <setBoolEnvVarDefined result="" value=""/>
*
* A general example for using environment variable nodes:
*
* <setBoolEnvVarDefined result="bHasNDK" value="%NDKROOT%"/>
* <setStringFromEnvVar result="NDKPath" value="%NDKROOT%"/>
*
* Boolean variables may also be set to the result of applying operators:
*
* <setBoolNot result="" source=""/>
* <setBoolAnd result="" arg1="" arg2=""/>
* <setBoolOr result="" arg1="" arg2=""/>
* <setBoolIsEqual result="" arg1="" arg2=""/>
* <setBoolIsLess result="" arg1="" arg2=""/>
* <setBoolIsLessEqual result="" arg1="" arg2=""/>
* <setBoolIsGreater result="" arg1="" arg2=""/>
* <setBoolIsGreaterEqual result="" arg1="" arg2=""/>
* <setBoolFromPropertyContains result="" ini="" section="" property="" contains=""/>
*
* Integer variables may use these arithmetic operations:
*
* <setIntAdd result="" arg1="" arg2=""/>
* <setIntSubtract result="" arg1="" arg2=""/>
* <setIntMultiply result="" arg1="" arg2=""/>
* <setIntDivide result="" arg1="" arg2=""/>
*
* Strings are manipulated with the following:
*
* <setStringAdd result="" arg1="" arg2=""/>
* <setStringSubstring result="" source="" start="" length=""/>
* <setStringReplace result="" source="" find="" with=""/>
*
* String length may be retrieved with:
*
* <setIntLength result="" source=""/>
*
* The index of a search string may be found in source with:
*
* <setIntFindString result="" source="" find=""/>
*
* The following shortcut string comparisons may also be used instead of using <setIntFindString>
* and checking the result:
*
* <setBoolStartsWith result="" source="" find=""/>
* <setBoolEndsWith result="" source="" find=""/>
* <setBoolContains result="" source="" find=""/>
*
* Messages are written to the log with this node:
*
* <log text=""/>
*
* Conditional execution uses the following form:
*
* <if condition="">
* <true>
* <!-- executes if boolean variable in condition is true -->
* </true>
* <false>
* <!-- executes if boolean variable in condition is false -->
* </false>
* </if>
*
* The <true> and <false> blocks are optional. The condition must be in a boolean variable.
* The boolean operator nodes may be combined to create a final state for more complex
* conditions:
*
* <setBoolNot result="notDistribution" source="$B(Distribution)/>
* <setBoolIsEqual result="isX86" arg1="$S(Architecture)" arg2="x86"/>
* <setBoolIsEqual result="isX86_64" arg2="$S(Architecture)" arg2="x86_64/">
* <setBoolOr result="isIntel" arg1="$B(isX86)" arg2="$B(isX86_64)"/>
* <setBoolAnd result="intelAndNotDistribution" arg1="$B(isIntel)" arg2="$B(notDistribution)"/>
* <if condition="intelAndNotDistribution">
* <true>
* <!-- do something for Intel if not a distribution build -->
* </true>
* </if>
*
* Note the "isIntel" could also be done like this:
*
* <setStringSubstring result="subarch" source="$S(Architecture)" start="0" length="3"/>
* <setBoolEquals result="isIntel" arg1="$S(subarch)" arg2="x86"/>
*
* Two shortcut nodes are available for conditional execution:
*
* <isArch arch="armeabi-armv7">
* <!-- do stuff -->
* </isArch>
*
* is the equivalent of:
*
* <setBoolEquals result="temp" arg1="$S(Architecture)" arg2="armeabi-armv7">
* <if condition="temp">
* <true>
* <!-- do stuff -->
* </true>
* </if>
*
* and
*
* <isDistribution>
* <!-- do stuff -->
* </isDistribution>
*
* is the equivalent of:
*
* <if condition="Distribution">
* <!-- do stuff -->
* </if>
*
* Execution may be stopped with:
*
* <return/>
*
* Loops may be created using these nodes:
*
* <while condition="">
* <!-- do stuff -->
* </while>
*
* <break/>
* <continue/>
*
* The <while> body will execute until the condition is false or a <break/> is hit. The
* <continue/> will restart execution of the loop if the condition is still true or exit.
*
* Note: <break/> outside a <while> body will act the same as <return/>
*
* Here is an example loop which writes 1 to 5 to the log, skipping 3. Note the update of the
* while condition should be done before the continue otherwise it may not exit.
*
* <setInt result="index" value="0"/>
* <setBool result="loopRun" value="true"/>
* <while condition="loopRun">
* <setIntAdd result="index" arg1="$I(index)" arg2="1"/>
* <setBoolIsLess result="loopRun" arg1="$I(index)" arg2="5"/>
* <setBoolIsEqual result="indexIs3" arg1="$I(index)" arg2="3"/>
* <if condition="indexIs3">
* <true>
* <continue/>
* </true>
* </if>
* <log text="$I(index)"/>
* </while>
*
* It is possible to use variable replacement in generating the result variable
* name as well. This makes the creation of arrays in loops possible:
*
* <setString result="array_$I(index)" value="element $I(index) in array"/>
*
* This may be retrieved using the following (value is treated as the variable
* name):
*
* <setStringFrom result="out" value="array_$I(index)"/>
*
* For boolean and integer types, you may use <setBoolFrom/> and <setIntFrom/>.
*
* Nodes for inserting text into the section are as follows:
*
* <insert> body </insert>
* <insertNewline/>
* <insertValue value=""/>
* <loadLibrary name="" failmsg=""/>
*
* The first one will insert either text or nodes into the returned section
* string. Please note you must use escaped characters for:
*
* < = &lt;
* > = &gt;
* & = &amp;
*
* <insertValue value=""/> evaluates variables in value before insertion. If value contains
* double quote ("), you must escape it with &quot;.
*
* <loadLibrary name="" failmsg=""/> is a shortcut to insert a system.LoadLibrary try/catch
* block with an optional logged message for failure to load case.
*
* You can do a search and replace in the Output with:
*
* <replace find="" with=""/>
*
* Note you can also manipulate the actual $S(Output) directly, the above are more efficient:
*
* <setStringAdd result="Input" arg1="$S(Output)" arg2="sample\n"/>
* <setStringReplace result="Input" source="$S(Output)" find=".LAUNCH" with=".INFO"/>
*
* XML manipulation uses the following nodes:
*
* <addElement tag="" name=""/>
* <addElements tag=""> body </addElements>
* <removeElement tag=""/>
* <setStringFromTag result="" tag=""/>
* <setStringFromAttribute result="" tag="" name=""/>
* <setStringFromTagText result="" tag=""/>
* <addAttribute tag="" name="" value=""/>
* <removeAttribute tag="" name=""/>
* <loopElements tag=""> instructions </loopElements>
*
* The current element is referenced with tag="$". Element variables are referenced with $varname
* since using $E(varname) will be expanded to the string equivalent of the XML.
*
* addElement, addElements, and removeElement by default are applied to all matching tags. An
* optional once="true" attribute may be added to only apply to first matching tag.
*
* <uses-permission>, <uses-feature>, and <uses-library> are updated with:
*
* <addPermission android:name="" .. />
* <addFeature android:name="" .. />
* <addLibrary android:name="" .. />
*
* Any attributes in the above commands are copied to the element added to the manifest so you
* can do the following, for example:
*
* <addFeature android:name="android.hardware.usb.host" android:required="true"/>
*
* Finally, these nodes allow copying of files useful for staging jar and so files:
*
* <copyFile src="" dst="" force=""/>
* <copyDir src="" dst="" force=""/>
*
* If force is false the file(s) are replaced only if length or timestamp don't match. Default is true.
*
* The following should be used as the base for the src and dst paths:
*
* $S(PluginDir) = directory the XML file was loaded from
* $S(EngineDir) = engine directory
* $S(BuildDir) = project's platform appropriate build directory
*
* While it is possible to write outside the APK directory, it is not recommended.
*
* If you must remove files (like development-only files from distribution builds) you can
* use this node:
*
* <deleteFiles filespec=""/>
*
* It is restricted to only removing files from the BuildDir. Here is example usage to remove
* the Oculus Signature Files (osig) from the assets directory:
*
* <deleteFiles filespec="assets/oculussig_*"/>
*
* The following sections are evaluated during the packaging or deploy stages:
*
* ** For all platforms **
* <!-- init section is always evaluated once per architecture -->
* <init> </init>
*
* ** Android Specific sections **
* <!-- optional updates applied to AndroidManifest.xml -->
