MakePri.exe format-specific indexers
This topic describes the format-specific indexers used by the MakePri.exe tool to generate its index of resources.
Note
MakePri.exe is installed when you check the Windows SDK for UWP Managed Apps option while installing the Windows Software Development Kit. It is installed to the path %WindowsSdkDir%bin\<WindowsTargetPlatformVersion>\x64\makepri.exe (as well as in folders named for the other architectures). For example, C:\Program Files (x86)\Windows Kits\10\bin\10.0.17713.0\x64\makepri.exe.
MakePri.exe is typically used with the new, versioned, or resourcepack commands. See MakePri.exe command-line options. In those cases it indexes source files to generate an index of resources. MakePri.exe uses various individual indexers to read different source resource files or containers for resources. The simplest indexer is the folder indexer, which indexes the contents of a folder, such as .jpg or .png images.
You identify format-specific indexers by specifying <indexer-config> elements within an <index> element of the MakePri.exe configuration file. The type attribute identifies the format-specific indexer that is used.
Resource containers encountered during indexing usually get their contents indexed rather than being added to the index themselves. For example, .resjson files that the folder indexer finds may be further indexed by a .resjson indexer, in which case the .resjson file itself does not appear in the index. Note an <indexer-config> element for the indexer associated with that container must be included in the configuration file for that to happen.
Typically, qualifiers found on a containing entity—such as a folder or a .resw file—are applied to all resources within it, such as the files within the folder, or the strings within the .resw file.
Folder
The folder indexer is identified by a type attribute of FOLDER. It indexes the contents of a folder, and determines resource qualifiers from the folder and filenames. Its configuration element conforms to the following schema.
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:simpleType name="ExclusionTypeList">
<xs:restriction base="xs:string">

</xs:complexType>
<xs:simpleType name="IndexerConfigFolderType">
<xs:restriction base="xs:string">
<xs:pattern value="((f|F)(o|O)(l|L)(d|D)(e|E)(r|R))"/>
</xs:restriction>
</xs:simpleType>
<xs:element name="indexer-config">

<xs:attribute name="filenameAsQualifier" type="xs:boolean" use="required"/>
<xs:attribute name="qualifierDelimiter" type="xs:string" use="required"/>
</xs:complexType>
</xs:element>
</xs:schema>
The qualifierDelimiter attribute specifies the character after which qualifiers are specified in a filename, ignoring the extension. The default is ".".
PRI
The PRI indexer is identified by a type attribute of PRI. It indexes the contents of a PRI file. You typically use it when indexing the resource contained within another assembly, DLL, SDK, or class library into the app's PRI.
All resource names, qualifiers and values contained in the PRI file are directly maintained in the new PRI file. The top level resource map, however is not maintained in the final PRI. Resource Maps are merged.
<xs:schema id="prifile" xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
<xs:simpleType name="IndexerConfigPriType">
<xs:restriction base="xs:string">
<xs:pattern value="((p|P)(r|R)(i|I))"/>
</xs:restriction>
</xs:simpleType>
<xs:element name="indexer-config">
<xs:complexType>
<xs:attribute name="type" type="IndexerConfigPriType" use="required"/>
</xs:complexType>
</xs:element>
</xs:schema>
PriInfo
The PriInfo indexer is identified by a type attribute of PRIINFO. It indexes the contents of a detailed dump file. You produce a detailed dump file by running makepri dump with the /dt detailed option. The configuration element for the indexer conforms to the following schema.
<xs:schema id="priinfo" xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
<xs:simpleType name="IndexerConfigPriInfoType">
<xs:restriction base="xs:string">
<xs:pattern value="((p|P)(r|R)(i|I)(i|I)(n|N)(f|F)(o|O))"/>
</xs:restriction>
</xs:simpleType>
<xs:element name="indexer-config">
<xs:complexType>
<xs:attribute name="type" type="IndexerConfigPriInfoType" use="required"/>
<xs:attribute name="emitStrings" type="xs:boolean" use="optional"/>
<xs:attribute name="emitPaths" type="xs:boolean" use="optional"/>
</xs:complexType>
</xs:element>
</xs:schema>
This configuration element allows for optional attributes to configure the behavior of the PriInfo indexer. The default value of emitStrings and emitPaths is true. If emitStrings is true then resource candidates with the type attribute set to "String" are be included in the index, otherwise they are excluded. If 'emitPaths' is true then resource candidates with the type attribute set to "Path" are included in the index, otherwise they are excluded.
Here is an example configuration that includes String resource types but skips Path resource types.
<indexer-config type="priinfo" emitStrings="true" emitPaths="false" />
To be indexed, a dump file must end with the extension .pri.xml, and must conform to the following schema.
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" >
<xs:simpleType name="candidateType">

MakePri.exe supports dump types 'Basic', 'Detailed', 'Schema', and 'Summary'. To configure MakePri.exe to emit the dump type that the PriInfo indexer can read, include "/DumpType Detailed" when using the dump command.
Several elements of the .pri.xml file are skipped by MakePri.exe. These elements are either computed during indexing, or are specified in the MakePri.exe configuration file. Resource names, qualifiers, and values that are contained within the dump file are directly maintained in the new PRI file. The top-level resource map, however, is not maintained in the final PRI. Resource Maps are merged as part of the indexing.
This is an example of a valid String type resource from a dump file.
<NamedResource name="SampleString " index="96" uri="ms-resource://SampleApp/resources/SampleString ">
<Decision index="2">
<QualifierSet index="1">
<Qualifier name="Language" value="EN-US" priority="900" scoreAsDefault="1.0" index="1"/>
</QualifierSet>
</Decision>
<Candidate type="String">
<QualifierSet index="1">
<Qualifier name="Language" value="EN-US" priority="900" scoreAsDefault="1.0" index="1"/>
</QualifierSet>
<Value>A Sample String Value</Value>
</Candidate>
</NamedResource>
This is an example of a valid Path type resource with two candidates from a dump file.
<NamedResource name="Sample.png" index="77" uri="ms-resource://SampleApp/Files/Images/Sample.png">
<Decision index="2">
<QualifierSet index="1">
<Qualifier name="Scale" value="180" priority="500" scoreAsDefault="1.0" index="1"/>
</QualifierSet>
<QualifierSet index="2">
<Qualifier name="Scale" value="140" priority="500" scoreAsDefault="0.7" index="2"/>
</QualifierSet>
</Decision>
<Candidate type="Path">
<QualifierSet index="1">
<Qualifier name="Scale" value="180" priority="500" scoreAsDefault="1.0" index="1"/>
</QualifierSet>
<Value>Images\Sample.scale-180.png</Value>
</Candidate>
<Candidate type="Path">
<QualifierSet index="2">
<Qualifier name="Scale" value="140" priority="500" scoreAsDefault="1.0" index="1"/>
</QualifierSet>
<Value>Images\Sample.scale-140.png</Value>
</Candidate>
</NamedResource>
ResFiles
The ResFiles indexer is identified by a type attribute of RESFILES. It indexes the contents of a .resfiles file. Its configuration element conforms to the following schema.
<xs:schema id="resx" xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
<xs:simpleType name="IndexerConfigResFilesType">
<xs:restriction base="xs:string">
<xs:pattern value="((r|R)(e|E)(s|S)(f|F)(i|I)(l|L)(e|E)(s|S))"/>
</xs:restriction>
</xs:simpleType>
<xs:element name="indexer-config">
<xs:complexType>
<xs:attribute name="type" type="IndexerConfigResFilesType" use="required"/>
<xs:attribute name="qualifierDelimiter" type="xs:string" use="required"/>
</xs:complexType>
</xs:element>
</xs:schema>
A .resfiles file is a text file containing a flat list of file paths. A .resfiles file can contain "//" comments. Here's an example.
Strings\component1\fr\elements.resjson Images\logo.scale-100.png Images\logo.scale-140.png Images\logo.scale-180.png
ResJSON
The ResJSON indexer is identified by a type attribute of RESJSON. It indexes the contents of a .resjson file, which is a string resource file. Its configuration element conforms to the following schema.
<xs:schema id="resjson" xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
<xs:simpleType name="IndexerConfigResJsonType">
<xs:restriction base="xs:string">
<xs:pattern value="((r|R)(e|E)(s|S)(j|J)(s|S)(o|O)(n|N))"/>
</xs:restriction>
</xs:simpleType>
<xs:element name="indexer-config">
<xs:complexType>
<xs:attribute name="type" type="IndexerConfigResJsonType" use="required"/>
<xs:attribute name="initialPath" type="xs:string" use="optional"/>
</xs:complexType>
</xs:element>
</xs:schema>
A .resjson file contains JSON text (see The application/json Media Type for JavaScript Object Notation (JSON)). The file must contain a single JSON object with hierarchical properties. Each property must either be another JSON object or a string value.
JSON properties with names that begin with an underscore ("_") are not compiled into the final PRI file, but are maintained in the log file.
The file can also contain "//" comments which are ignored during parsing.
The initialPath attribute places all resources under this initial path by prepending it to the name of the resource. You would typically use this when indexing class library resources. The default is blank.
ResW
The ResW indexer is identified by a type attribute of RESW. It indexes the contents of a .resw file, which is a string resource file. Its configuration element conforms to the following schema.
<xs:schema id="resw" xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
<xs:simpleType name="IndexerConfigResxType">
<xs:restriction base="xs:string">
<xs:pattern value="((r|R)(e|E)(s|S)(w|W))"/>
</xs:restriction>
</xs:simpleType>
<xs:element name="indexer-config">
<xs:complexType>
<xs:attribute name="type" type="IndexerConfigResxType" use="required"/>
<xs:attribute name="convertDotsToSlashes" type="xs:boolean" use="required"/>
<xs:attribute name="initialPath" type="xs:string" use="optional"/>
</xs:complexType>
</xs:element>

The convertDotsToSlashes attribute converts all dot (".") characters found in resource names (data element name attributes) to a forward slash "/", except when the dot characters are between a "[" and "]".
The initialPath attribute places all resources under this initial path by prepending it to the name of the resource. You typically use this when indexing class library resources. The default is blank.
