Clients may use the API by writing query files to a specific location in a build tree to request zero or more \fI\%Object Kinds\fP\&. When CMake generates the buildsystem in that build tree it will read the query files and write reply files for the client to read. .sp The file\-based API uses a \fB/.cmake/api/\fP directory at the top of a build tree. The API is versioned to support changes to the layout of files within the API directory. API file layout versioning is orthogonal to the versioning of \fI\%Object Kinds\fP used in replies. This version of CMake supports only one API version, \fI\%API v1\fP\&. .sp New in version 3.27: Projects may also submit queries for the current run using the \fI\%cmake_file_api()\fP command. .SH API V1 .sp API v1 is housed in the \fB/.cmake/api/v1/\fP directory. It has the following subdirectories: .INDENT 0.0 .TP .B \fBquery/\fP Holds query files written by clients. These may be \fI\%v1 Shared Stateless Query Files\fP, \fI\%v1 Client Stateless Query Files\fP, or \fI\%v1 Client Stateful Query Files\fP\&. .TP .B \fBreply/\fP Holds reply files written by CMake whenever it runs to generate a build system. These are indexed by a \fI\%v1 Reply Index File\fP file that may reference additional \fI\%v1 Reply Files\fP\&. CMake owns all reply files. Clients must never remove them. .sp Clients may look for and read a reply index file at any time. Clients may optionally create the \fBreply/\fP directory at any time and monitor it for the appearance of a new reply index file. .UNINDENT .SS v1 Shared Stateless Query Files .sp Shared stateless query files allow clients to share requests for major versions of the \fI\%Object Kinds\fP and get all requested versions recognized by the CMake that runs. .sp Clients may create shared requests by creating empty files in the \fBv1/query/\fP directory. The form is: .INDENT 0.0 .INDENT 3.5 .sp .EX /.cmake/api/v1/query/\-v .EE .UNINDENT .UNINDENT .sp where \fB\fP is one of the \fI\%Object Kinds\fP, \fB\-v\fP is literal, and \fB\fP is the major version number. .sp Files of this form are stateless shared queries not owned by any specific client. Once created they should not be removed without external client coordination or human intervention. .SS v1 Client Stateless Query Files .sp Client stateless query files allow clients to create owned requests for major versions of the \fI\%Object Kinds\fP and get all requested versions recognized by the CMake that runs. .sp Clients may create owned requests by creating empty files in client\-specific query subdirectories. The form is: .INDENT 0.0 .INDENT 3.5 .sp .EX /.cmake/api/v1/query/client\-/\-v .EE .UNINDENT .UNINDENT .sp where \fBclient\-\fP is literal, \fB\fP is a string uniquely identifying the client, \fB\fP is one of the \fI\%Object Kinds\fP, \fB\-v\fP is literal, and \fB\fP is the major version number. Each client must choose a unique \fB\fP identifier via its own means. .sp Files of this form are stateless queries owned by the client \fB\fP\&. The owning client may remove them at any time. .SS v1 Client Stateful Query Files .sp Stateful query files allow clients to request a list of versions of each of the \fI\%Object Kinds\fP and get only the most recent version recognized by the CMake that runs. .sp Clients may create owned stateful queries by creating \fBquery.json\fP files in client\-specific query subdirectories. The form is: .INDENT 0.0 .INDENT 3.5 .sp .EX /.cmake/api/v1/query/client\-/query.json .EE .UNINDENT .UNINDENT .sp where \fBclient\-\fP is literal, \fB\fP is a string uniquely identifying the client, and \fBquery.json\fP is literal. Each client must choose a unique \fB\fP identifier via its own means. .sp \fBquery.json\fP files are stateful queries owned by the client \fB\fP\&. The owning client may update or remove them at any time. When a given client installation is updated it may then update the stateful query it writes to build trees to request newer object versions. This can be used to avoid asking CMake to generate multiple object versions unnecessarily. .sp A \fBquery.json\fP file must contain a JSON object: .INDENT 0.0 .INDENT 3.5 .sp .EX { \(dqrequests\(dq: [ { \(dqkind\(dq: \(dq\(dq , \(dqversion\(dq: 1 }, { \(dqkind\(dq: \(dq\(dq , \(dqversion\(dq: { \(dqmajor\(dq: 1, \(dqminor\(dq: 2 } }, { \(dqkind\(dq: \(dq\(dq , \(dqversion\(dq: [2, 1] }, { \(dqkind\(dq: \(dq\(dq , \(dqversion\(dq: [2, { \(dqmajor\(dq: 1, \(dqminor\(dq: 2 }] }, { \(dqkind\(dq: \(dq\(dq , \(dqversion\(dq: 1, \(dqclient\(dq: {} }, { \(dqkind\(dq: \(dq...\(dq } ], \(dqclient\(dq: {} } .EE .UNINDENT .UNINDENT .sp The members are: .INDENT 0.0 .TP .B \fBrequests\fP A JSON array containing zero or more requests.

Versions have major and minor components following semantic version conventions. The value must be .INDENT 7.0 .IP \(bu 2 a JSON integer specifying a (non\-negative) major version number, or .IP \(bu 2 a JSON object containing \fBmajor\fP and (optionally) \fBminor\fP members specifying non\-negative integer version components, or .IP \(bu 2 a JSON array whose elements are each one of the above. .UNINDENT .TP .B \fBclient\fP Optional member reserved for use by the client. This value is preserved in the reply written for the client in the \fI\%v1 Reply Index File\fP but is otherwise ignored. Clients may use this to pass custom information with a request through to its reply. .UNINDENT .sp For each requested object kind CMake will choose the \fIfirst\fP version that it recognizes for that kind among those listed in the request. The response will use the selected \fImajor\fP version with the highest \fIminor\fP version known to the running CMake for that major version. Therefore clients should list all supported major versions in preferred order along with the minimal minor version required for each major version. .TP .B \fBclient\fP Optional member reserved for use by the client. This value is preserved in the reply written for the client in the \fI\%v1 Reply Index File\fP but is otherwise ignored. Clients may use this to pass custom information with a query through to its reply. .UNINDENT .sp Other \fBquery.json\fP top\-level members are reserved for future use. If present they are ignored for forward compatibility. .SS v1 Reply Index File .sp CMake writes an \fBindex\-*.json\fP file to the \fBv1/reply/\fP directory whenever it runs to generate a build system. Clients must read the reply index file first and may read other \fI\%v1 Reply Files\fP only by following references. The form of the reply index file name is: .INDENT 0.0 .INDENT 3.5 .sp .EX /.cmake/api/v1/reply/index\-.json .EE .UNINDENT .UNINDENT .sp where \fBindex\-\fP is literal and \fB\fP is an unspecified name selected by CMake. Whenever a new index file is generated it is given a new name and any old one is deleted. During the short time between these steps there may be multiple index files present; the one with the largest name in lexicographic order is the current index file. .sp The reply index file contains a JSON object: .INDENT 0.0 .INDENT 3.5 .sp .EX { \(dqcmake\(dq: { \(dqversion\(dq: { \(dqmajor\(dq: 3, \(dqminor\(dq: 14, \(dqpatch\(dq: 0, \(dqsuffix\(dq: \(dq\(dq, \(dqstring\(dq: \(dq3.14.0\(dq, \(dqisDirty\(dq: false }, \(dqpaths\(dq: { \(dqcmake\(dq: \(dq/prefix/bin/cmake\(dq, \(dqctest\(dq: \(dq/prefix/bin/ctest\(dq, \(dqcpack\(dq: \(dq/prefix/bin/cpack\(dq, \(dqroot\(dq: \(dq/prefix/share/cmake\-3.14\(dq }, \(dqgenerator\(dq: { \(dqmultiConfig\(dq: false, \(dqname\(dq: \(dqUnix Makefiles\(dq } }, \(dqobjects\(dq: [ { \(dqkind\(dq: \(dq\(dq, \(dqversion\(dq: { \(dqmajor\(dq: 1, \(dqminor\(dq: 0 }, \(dqjsonFile\(dq: \(dq\(dq }, { \(dq...\(dq: \(dq...\(dq } ], \(dqreply\(dq: { \(dq\-v\(dq: { \(dqkind\(dq: \(dq\(dq, \(dqversion\(dq: { \(dqmajor\(dq: 1, \(dqminor\(dq: 0 }, \(dqjsonFile\(dq: \(dq\(dq }, \(dq\(dq: { \(dqerror\(dq: \(dqunknown query file\(dq }, \(dq...\(dq: {}, \(dqclient\-\(dq: { \(dq\-v\(dq: { \(dqkind\(dq: \(dq\(dq, \(dqversion\(dq: { \(dqmajor\(dq: 1, \(dqminor\(dq: 0 }, \(dqjsonFile\(dq: \(dq\(dq }, \(dq\(dq: { \(dqerror\(dq: \(dqunknown query file\(dq }, \(dq...\(dq: {}, \(dqquery.json\(dq: { \(dqrequests\(dq: [ {}, {}, {} ], \(dqresponses\(dq: [ { \(dqkind\(dq: \(dq\(dq, \(dqversion\(dq: { \(dqmajor\(dq: 1, \(dqminor\(dq: 0 }, \(dqjsonFile\(dq: \(dq\(dq }, { \(dqerror\(dq: \(dqunknown query file\(dq }, { \(dq...\(dq: {} } ], \(dqclient\(dq: {} } } } } .EE .UNINDENT .UNINDENT .sp The members are: .INDENT 0.0 .TP .B \fBcmake\fP A JSON object containing information about the instance of CMake that generated the reply.

The value is a \fI\%v1 Reply File Reference\fP to the corresponding reply file for that object kind and version. .TP .B \fB\fP A member of this form appears for each of the \fI\%v1 Shared Stateless Query Files\fP that CMake did not recognize. The value is a JSON object with a single \fBerror\fP member containing a string with an error message indicating that the query file is unknown. .TP .B \fBclient\-\fP A member of this form appears for each client\-owned directory holding \fI\%v1 Client Stateless Query Files\fP\&.

Otherwise, this member is a JSON object mirroring the content of the \fBquery.json\fP file. The members are: .INDENT 7.0 .TP .B \fBclient\fP A copy of the \fBquery.json\fP file \fBclient\fP member, if it exists. .TP .B \fBrequests\fP A copy of the \fBquery.json\fP file \fBrequests\fP member, if it exists. .TP .B \fBresponses\fP If the \fBquery.json\fP file \fBrequests\fP member is missing or invalid, this member is a JSON object with a single \fBerror\fP member containing a string with an error message.

The names of these files are unspecified and must not be interpreted by clients. Clients must first read the \fI\%v1 Reply Index File\fP and follow references to the names of the desired response objects. .sp Reply files (including the index file) will never be replaced by files of the same name but different content. This allows a client to read the files concurrently with a running CMake that may generate a new reply. However, after generating a new reply CMake will attempt to remove reply files from previous runs that it did not just write. If a client attempts to read a reply file referenced by the index but finds the file missing, that means a concurrent CMake has generated a new reply. The client may simply start again by reading the new reply index file. .SH OBJECT KINDS .sp The CMake file\-based API reports semantic information about the build system using the following kinds of JSON objects. Each kind of object is versioned independently using semantic versioning with major and minor components. Every kind of object has the form: .INDENT 0.0 .INDENT 3.5 .sp .EX { \(dqkind\(dq: \(dq\(dq, \(dqversion\(dq: { \(dqmajor\(dq: 1, \(dqminor\(dq: 0 }, \(dq...\(dq: {} } .EE .UNINDENT .UNINDENT .sp The \fBkind\fP member is a string specifying the object kind name. The \fBversion\fP member is a JSON object with \fBmajor\fP and \fBminor\fP members specifying integer components of the object kind\(aqs version. Additional top\-level members are specific to each object kind. .SS Object Kind \(dqcodemodel\(dq .sp The \fBcodemodel\fP object kind describes the build system structure as modeled by CMake. .sp There is only one \fBcodemodel\fP object major version, version 2. Version 1 does not exist to avoid confusion with that from \fI\%cmake\-server(7)\fP mode. .SS \(dqcodemodel\(dq version 2 .sp \fBcodemodel\fP object version 2 is a JSON object: .INDENT 0.0 .INDENT 3.5 .sp .EX { \(dqkind\(dq: \(dqcodemodel\(dq, \(dqversion\(dq: { \(dqmajor\(dq: 2, \(dqminor\(dq: 6 }, \(dqpaths\(dq: { \(dqsource\(dq: \(dq/path/to/top\-level\-source\-dir\(dq, \(dqbuild\(dq: \(dq/path/to/top\-level\-build\-dir\(dq }, \(dqconfigurations\(dq: [ { \(dqname\(dq: \(dqDebug\(dq, \(dqdirectories\(dq: [ { \(dqsource\(dq: \(dq.\(dq, \(dqbuild\(dq: \(dq.\(dq, \(dqchildIndexes\(dq: [ 1 ], \(dqprojectIndex\(dq: 0, \(dqtargetIndexes\(dq: [ 0 ], \(dqhasInstallRule\(dq: true, \(dqminimumCMakeVersion\(dq: { \(dqstring\(dq: \(dq3.14\(dq }, \(dqjsonFile\(dq: \(dq\(dq }, { \(dqsource\(dq: \(dqsub\(dq, \(dqbuild\(dq: \(dqsub\(dq, \(dqparentIndex\(dq: 0, \(dqprojectIndex\(dq: 0, \(dqtargetIndexes\(dq: [ 1 ], \(dqminimumCMakeVersion\(dq: { \(dqstring\(dq: \(dq3.14\(dq }, \(dqjsonFile\(dq: \(dq\(dq } ], \(dqprojects\(dq: [ { \(dqname\(dq: \(dqMyProject\(dq, \(dqdirectoryIndexes\(dq: [ 0, 1 ], \(dqtargetIndexes\(dq: [ 0, 1 ] } ], \(dqtargets\(dq: [ { \(dqname\(dq: \(dqMyExecutable\(dq, \(dqdirectoryIndex\(dq: 0, \(dqprojectIndex\(dq: 0, \(dqjsonFile\(dq: \(dq\(dq }, { \(dqname\(dq: \(dqMyLibrary\(dq, \(dqdirectoryIndex\(dq: 1, \(dqprojectIndex\(dq: 0, \(dqjsonFile\(dq: \(dq\(dq } ] } ] } .EE .UNINDENT .UNINDENT .sp The members specific to \fBcodemodel\fP objects are: .INDENT 0.0 .TP .B \fBpaths\fP A JSON object containing members: .INDENT 7.0 .TP .B \fBsource\fP A string specifying the absolute path to the top\-level source directory, represented with forward slashes. .TP .B \fBbuild\fP A string specifying the absolute path to the top\-level build directory, represented with forward slashes. .UNINDENT .TP .B \fBconfigurations\fP A JSON array of entries corresponding to available build configurations.
