NAMEcmake-file-api − CMake File-Based API

INTRODUCTIONCMake provides a file−based API that clients may use to get semantic information about the buildsystems CMake generates. Clients may use the API by writing query files to a specific location in a build tree to request zero or more Object Kinds. When CMake generates the buildsystem in that build tree it will read the query files and write reply files for the client to read. The file−based API uses a <build>/.cmake/api/ 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 Object Kinds used in replies. This version of CMake supports only one API version, API v1.

API V1API v1 is housed in the <build>/.cmake/api/v1/ directory. It has the following subdirectories: query/ Holds query files written by clients. These may be v1 Shared Stateless Query Files, v1 Client Stateless Query Files, or v1 Client Stateful Query Files. reply/ Holds reply files written by CMake whenever it runs to generate a build system. These are indexed by a v1 Reply Index File file that may reference additional v1 Reply Files. CMake owns all reply files. Clients must never remove them. Clients may look for and read a reply index file at any time. Clients may optionally create the reply/ directory at any time and monitor it for the appearance of a new reply index file.

v1 Shared Stateless Query FilesShared stateless query files allow clients to share requests for major versions of the Object Kinds and get all requested versions recognized by the CMake that runs. Clients may create shared requests by creating empty files in the v1/query/ directory. The form is: <build>/.cmake/api/v1/query/<kind>−v<major> where <kind> is one of the Object Kinds, −v is literal, and <major> is the major version number. 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.

v1 Client Stateless Query FilesClient stateless query files allow clients to create owned requests for major versions of the Object Kinds and get all requested versions recognized by the CMake that runs. Clients may create owned requests by creating empty files in client−specific query subdirectories. The form is: <build>/.cmake/api/v1/query/client−<client>/<kind>−v<major> where client− is literal, <client> is a string uniquely identifying the client, <kind> is one of the Object Kinds, −v is literal, and <major> is the major version number. Each client must choose a unique <client> identifier via its own means. Files of this form are stateless queries owned by the client <client>. The owning client may remove them at any time.

v1 Client Stateful Query FilesStateful query files allow clients to request a list of versions of each of the Object Kinds and get only the most recent version recognized by the CMake that runs. Clients may create owned stateful queries by creating query.json files in client−specific query subdirectories. The form is: <build>/.cmake/api/v1/query/client−<client>/query.json where client− is literal, <client> is a string uniquely identifying the client, and query.json is literal. Each client must choose a unique <client> identifier via its own means. query.json files are stateful queries owned by the client <client>. 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. A query.json file must contain a JSON object: { "requests": [ { "kind": "<kind>" , "version": 1 }, { "kind": "<kind>" , "version": { "major": 1, "minor": 2 } }, { "kind": "<kind>" , "version": [2, 1] }, { "kind": "<kind>" , "version": [2, { "major": 1, "minor": 2 }] }, { "kind": "<kind>" , "version": 1, "client": {} }, { "kind": "..." } ], "client": {} } The members are: requests A JSON array containing zero or more requests. Each request is a JSON object with members: kind Specifies one of the Object Kinds to be included in the reply. version Indicates the version(s) of the object kind that the client understands. Versions have major and minor components following semantic version conventions. The value must be • a JSON integer specifying a (non−negative) major version number, or • a JSON object containing major and (optionally) minor members specifying non−negative integer version components, or • a JSON array whose elements are each one of the above. client Optional member reserved for use by the client. This value is preserved in the reply written for the client in the v1 Reply Index File but is otherwise ignored. Clients may use this to pass custom information with a request through to its reply. For each requested object kind CMake will choose the first version that it recognizes for that kind among those listed in the request. The response will use the selected major version with the highest minor 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. client Optional member reserved for use by the client. This value is preserved in the reply written for the client in the v1 Reply Index File but is otherwise ignored. Clients may use this to pass custom information with a query through to its reply. Other query.json top−level members are reserved for future use. If present they are ignored for forward compatibility.

v1 Reply Index FileCMake writes an index−*.json file to the v1/reply/ directory whenever it runs to generate a build system. Clients must read the reply index file first and may read other v1 Reply Files only by following references. The form of the reply index file name is: <build>/.cmake/api/v1/reply/index−<unspecified>.json where index− is literal and <unspecified> 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. The reply index file contains a JSON object: { "cmake": { "version": { "major": 3, "minor": 14, "patch": 0, "suffix": "", "string": "3.14.0", "isDirty": false }, "paths": { "cmake": "/prefix/bin/cmake", "ctest": "/prefix/bin/ctest", "cpack": "/prefix/bin/cpack", "root": "/prefix/share/cmake−3.14" }, "generator": { "multiConfig": false, "name": "Unix Makefiles" } }, "objects": [ { "kind": "<kind>", "version": { "major": 1, "minor": 0 }, "jsonFile": "<file>" }, { "...": "..." } ], "reply": { "<kind>−v<major>": { "kind": "<kind>", "version": { "major": 1, "minor": 0 }, "jsonFile": "<file>" }, "<unknown>": { "error": "unknown query file" }, "...": {}, "client−<client>": { "<kind>−v<major>": { "kind": "<kind>", "version": { "major": 1, "minor": 0 }, "jsonFile": "<file>" }, "<unknown>": { "error": "unknown query file" }, "...": {}, "query.json": { "requests": [ {}, {}, {} ], "responses": [ { "kind": "<kind>", "version": { "major": 1, "minor": 0 }, "jsonFile": "<file>" }, { "error": "unknown query file" }, { "...": {} } ], "client": {} } } } } The members are: cmake A JSON object containing information about the instance of CMake that generated the reply. It contains members: version A JSON object specifying the version of CMake with members: major, minor, patch Integer values specifying the major, minor, and patch version components. suffix A string specifying the version suffix, if any, e.g. g0abc3. string A string specifying the full version in the format <major>.<minor>.<patch>[−<suffix>]. isDirty A boolean indicating whether the version was built from a version controlled source tree with local modifications. paths A JSON object specifying paths to things that come with CMake. It has members for cmake, ctest, and cpack whose values are JSON strings specifying the absolute path to each tool, represented with forward slashes. It also has a root member for the absolute path to the directory containing CMake resources like the Modules/ directory (see CMAKE_ROOT). generator A JSON object describing the CMake generator used for the build. It has members: multiConfig A boolean specifying whether the generator supports multiple output configurations. name A string specifying the name of the generator. platform If the generator supports CMAKE_GENERATOR_PLATFORM, this is a string specifying the generator platform name. objects A JSON array listing all versions of all Object Kinds generated as part of the reply. Each array entry is a v1 Reply File Reference. reply A JSON object mirroring the content of the query/ directory that CMake loaded to produce the reply. The members are of the form <kind>−v<major> A member of this form appears for each of the v1 Shared Stateless Query Files that CMake recognized as a request for object kind <kind> with major version <major>. The value is a v1 Reply File Reference to the corresponding reply file for that object kind and version. <unknown> A member of this form appears for each of the v1 Shared Stateless Query Files that CMake did not recognize. The value is a JSON object with a single error member containing a string with an error message indicating that the query file is unknown. client−<client> A member of this form appears for each client−owned directory holding v1 Client Stateless Query Files. The value is a JSON object mirroring the content of the query/client−<client>/ directory. The members are of the form: <kind>−v<major> A member of this form appears for each of the v1 Client Stateless Query Files that CMake recognized as a request for object kind <kind> with major version <major>. The value is a v1 Reply File Reference to the corresponding reply file for that object kind and version. <unknown> A member of this form appears for each of the v1 Client Stateless Query Files that CMake did not recognize. The value is a JSON object with a single error member containing a string with an error message indicating that the query file is unknown. query.json This member appears for clients using v1 Client Stateful Query Files. If the query.json file failed to read or parse as a JSON object, this member is a JSON object with a single error member containing a string with an error message. Otherwise, this member is a JSON object mirroring the content of the query.json file. The members are: client A copy of the query.json file client member, if it exists. requests A copy of the query.json file requests member, if it exists. responses If the query.json file requests member is missing or invalid, this member is a JSON object with a single error member containing a string with an error message. Otherwise, this member contains a JSON array with a response for each entry of the requests array, in the same order. Each response is • a JSON object with a single error member containing a string with an error message, or • a v1 Reply File Reference to the corresponding reply file for the requested object kind and selected version. After reading the reply index file, clients may read the other v1 Reply Files it references.

v1 Reply File ReferenceThe reply index file represents each reference to another reply file using a JSON object with members: kind A string specifying one of the Object Kinds. version A JSON object with members major and minor specifying integer version components of the object kind. jsonFile A JSON string specifying a path relative to the reply index file to another JSON file containing the object.

v1 Reply FilesReply files containing specific Object Kinds are written by CMake. The names of these files are unspecified and must not be interpreted by clients. Clients must first read the v1 Reply Index File and and follow references to the names of the desired response objects. 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.

OBJECT KINDSThe 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: { "kind": "<kind>", "version": { "major": 1, "minor": 0 }, "...": {} } The kind member is a string specifying the object kind name. The version member is a JSON object with major and minor members specifying integer components of the object kind’s version. Additional top−level members are specific to each object kind.

Object Kind “codemodel”The codemodel object kind describes the build system structure as modeled by CMake. There is only one codemodel object major version, version 2. Version 1 does not exist to avoid confusion with that from cmake−server(7) mode.

“codemodel” version 2codemodel object version 2 is a JSON object: { "kind": "codemodel", "version": { "major": 2, "minor": 1 }, "paths": { "source": "/path/to/top−level−source−dir", "build": "/path/to/top−level−build−dir" }, "configurations": [ { "name": "Debug", "directories": [ { "source": ".", "build": ".", "childIndexes": [ 1 ], "projectIndex": 0, "targetIndexes": [ 0 ], "hasInstallRule": true, "minimumCMakeVersion": { "string": "3.14" } }, { "source": "sub", "build": "sub", "parentIndex": 0, "projectIndex": 0, "targetIndexes": [ 1 ], "minimumCMakeVersion": { "string": "3.14" } } ], "projects": [ { "name": "MyProject", "directoryIndexes": [ 0, 1 ], "targetIndexes": [ 0, 1 ] } ], "targets": [ { "name": "MyExecutable", "directoryIndex": 0, "projectIndex": 0, "jsonFile": "<file>" }, { "name": "MyLibrary", "directoryIndex": 1, "projectIndex": 0, "jsonFile": "<file>" } ] } ] } The members specific to codemodel objects are: paths A JSON object containing members: source A string specifying the absolute path to the top−level source directory, represented with forward slashes. build A string specifying the absolute path to the top−level build directory, represented with forward slashes. configurations A JSON array of entries corresponding to available build configurations.

The members of each entry are: path A string specifying the path to an input file to CMake, represented with forward slashes. If the file is inside the top−level source directory then the path is specified relative to that directory. Otherwise the path is absolute. isGenerated Optional member that is present with boolean value true if the path specifies a file that is under the top−level build directory and the build is out−of−source. This member is not available on in−source builds. isExternal Optional member that is present with boolean value true if the path specifies a file that is not under the top−level source or build directories. isCMake Optional member that is present with boolean value true if the path specifies a file in the CMake installation.
