62 | 63 | 64 | # [Overview ▲](#___top "click to go to top of document") 65 | 66 | Cmake_check is a linter for the [CMake language](https://cmake.org). It takes a set of user-defined 67 | rules and reports violations for CMakeLists.txt files and CMake modules. 68 | CMake_check is a command line application suitable for continuous integration checks. This is 69 | especially useful for large source trees with hundreds of CMake files. 70 | Cmake_check can be used to enforce a certain coding style or project/company guidelines. It is 71 | written in TypeScript and runs on every platform where node.js is available. 72 | 73 | Features are: 74 | - recursive check of all CMake files in a given directory 75 | - allows combination of checks to form custom rules 76 | - a rule may consist of any number of [checks](doc/Checks.md) 77 | - provides warning output (msbuild format) that can be used by the 78 | [jenkins warnings plugin](https://wiki.jenkins.io/display/JENKINS/Warnings+Plugin) 79 | 80 | Available checks: 81 | - require commands to exist (or not exist) 82 | - allow white-listed commands only (to limit the use of custom functions) 83 | 84 | Planned checks: 85 | - require a specific command order 86 | - constraints on specific command arguments 87 | - constraints on paths (e.g. no ..) 88 | - comment checks 89 | - maximum line length 90 | - indentation checks 91 | 92 | 93 | ## [Binaries ▲](#___top "click to go to top of document") 94 | Each [release](https://github.com/DaelDe/cmake_check/releases) comes with a set 95 | of Linux and Windows binaries. 96 | 97 | 98 | ## [NPM ▲](#___top "click to go to top of document") 99 | Install [NodeJS](https://nodejs.org/) (version > 8.11). 100 | ```sh 101 | npm install -g cmake_check 102 | ``` 103 | 104 | 105 | # [Versioning ▲](#___top "click to go to top of document") 106 | Cmake_check uses [semantic versioning](https://semver.org/). 107 | 108 | 109 | # [Basic Usage ▲](#___top "click to go to top of document") 110 | The basic use is: 111 | ```sh 112 | cmake_check -i 113 | ``` 114 | or with custom configuration: 115 | ```sh 116 | cmake_check -c -i 117 | ``` 118 | 119 | All CMake files in the given input folders are analyzed with the given configuration. 120 | All warnings are written to stdout. 121 | 122 | For more information and further available options call `cmake_check -h`. 123 | 124 | 125 | ## [Configuration ▲](#___top "click to go to top of document") 126 | The documentation for the cmake_check configuration is available on 127 | a [separate page](doc/Configuration.adoc). 128 | 129 | 130 | # [How It Works ▲](#___top "click to go to top of document") 131 | 132 | Cmake_check uses a [parser-generator](https://github.com/pegjs/pegjs) 133 | and a [grammar](https://github.com/DaelDe/cmake_check/blob/readme/res/cmake.pegjs) 134 | to create a parser of the [CMake language](https://cmake.org/cmake/help/latest/manual/cmake-language.7.html). 135 | All CMakeLists.txt files from input are parsed to a structured object. 136 | All configured checks are executed on that object. Failed checks are 137 | printed as warnings. 138 | 139 | 140 | # [Limitations](#___top "click to go to top of document") 141 | - the language parser will fail on CMakeLists.txt files that do not conform to the CMake language 142 | - these errors are reported by CMake itself, a successful run of CMake on the input files is a precondition for cmake_check 143 | 144 | 145 | # [Features under development ▲](#___top "click to go to top of document") 146 | See the [development board](https://github.com/DaelDe/cmake_check/projects/2) for issues that are in work. 147 | 148 | -------------------------------------------------------------------------------- /bin/cmake_check: -------------------------------------------------------------------------------- 1 | #!/usr/bin/env node 2 | 3 | require('../lib/Main.js') 4 | -------------------------------------------------------------------------------- /doc/Checks.adoc: -------------------------------------------------------------------------------- 1 | :toc: 2 | :toclevels: 1 3 | 4 | ifdef::env-github[] 5 | :tip-caption: :bulb: 6 | :note-caption: :information_source: 7 | :important-caption: :heavy_exclamation_mark: 8 | :caution-caption: :fire: 9 | :warning-caption: :warning: 10 | endif::[] 11 | 12 | = Checker documentation 13 | 14 | This document describes all the available checks and their configuration. 15 | 16 | == C001 - Command Existence 17 | `id: C001` 18 | 19 | Check C001 can be used to verify that certain CMake commands exist or not exist. 20 | This check can be used to: 21 | 22 | - forbid specific CMake vocabulary 23 | - force the existence of certain commands (e.g. `target_link_libraries` for target CMakeLists) 24 | 25 | === Config 26 | Example: 27 | ```.json 28 | "config": { 29 | "commands": [ 30 | { 31 | "name": "^add_library|add_executable$", 32 | "occurences": "1" 33 | }, 34 | { 35 | "name": "^target_link_libraries$", 36 | "occurences": "1+" 37 | }, 38 | { 39 | "name": "^target_include_directories$", 40 | "occurences": "1" 41 | } 42 | ] 43 | } 44 | ``` 45 | 46 | ==== commands 47 | `required, type: command[]` 48 | 49 | The list of commands affected by the rule. 50 | 51 | ==== command 52 | 53 | ===== name 54 | `required, type: string` 55 | 56 | A regular expression that defines the affected command(s). 57 | 58 | - `target` matches any command with target in its name 59 | - `^target_include_directories$` matches exactly the `target_include_directories` command 60 | - `^command1|command2$` matches exactly `command1` or `command2` 61 | 62 | ===== occurences 63 | `required, type: string` 64 | 65 | An expression that defines the allowed number of appearances of command. It consists of any number followed 66 | by an optional `+` sign. 67 | 68 | - `0` zero occurences, can be used to forbid commands completely 69 | - `0+` zero or more occurences 70 | - `1+` one or more ocvcurences 71 | 72 | 73 | == C003 - Command Whitelist 74 | `id: C003` 75 | 76 | Check C003 should be used to list *all* allowed CMake commands. Its primary use is to control 77 | user defined commands. A warning is generated for each command that is not in the list. 78 | 79 | To explicitly forbid commands use check `C001`. 80 | 81 | === Config 82 | 83 | ==== commands 84 | `required, type: string[]` 85 | 86 | The list of commands affected by the rule. 87 | -------------------------------------------------------------------------------- /doc/Configuration.adoc: -------------------------------------------------------------------------------- 1 | :toc: 2 | :toclevels: 4 3 | 4 | ifdef::env-github[] 5 | :tip-caption: :bulb: 6 | :note-caption: :information_source: 7 | :important-caption: :heavy_exclamation_mark: 8 | :caution-caption: :fire: 9 | :warning-caption: :warning: 10 | endif::[] 11 | 12 | = The cmake_check configuration file 13 | 14 | == Intro 15 | This document is all you need to know about what's required in your cmake_check configuration file. 16 | It must be actual JSON, not just a JavaScript object literal. It contains of one JSON object, its 17 | members are described in the following sections. 18 | 19 | As a reference, a commented JSON link:../res/config.schema.json[schema] exists. 20 | 21 | An example configuration as a basic starting point link:../res/config.json[exists]. 22 | 23 | == crawler 24 | `required, type:object` 25 | 26 | The _crawler_ object contains options for the directory traversal during search for CMake files. 27 | 28 | === excludePaths 29 | `optional, type:string[]` 30 | 31 | A list of regular expressions that match directories that shall be skipped during traversal. 32 | Some folders like `.git` contain a lot of files but are not relevant for cmake_check, 33 | excluding them reduces analysis time. Also add directories that contain uninteresting 34 | files and should be excluded from analysis like 3rd party code. 35 | 36 | [source,json] 37 | ---- 38 | "excludePaths":["\\.git$", "\\.svn$"] 39 | ---- 40 | 41 | NOTE: When a character needs to be escaped in the regular expression, 2 backslashes are needed. 42 | If a path under windows should be excluded, 4 backslashes are needed: `folder\\\\folder1`. 43 | 44 | == cRules 45 | `required, type:Rule[]` 46 | 47 | The collection of rules that should be applied to CMake files. At least one 48 | rule is required. 49 | 50 | === Rule 51 | `type:object` 52 | 53 | A rule is a logical element that describes a requirement to CMake files (an element 54 | of a coding guideline). A rule consists of any number of checks. The rule is checked 55 | for each input file and passes when all checks pass. 56 | 57 | Example: 58 | ```.json 59 | { 60 | "id": "CM-003", 61 | "appliesTo": [ 62 | "TargetCMakeLists" 63 | ], 64 | "name": "Variable usage is prohibited", 65 | "enabled": true, 66 | "checks": [ 67 | { 68 | "id": "C001", 69 | "config": { 70 | "commands": [ 71 | { 72 | "name": "^set$", 73 | "occurences": "0" 74 | } 75 | ] 76 | } 77 | } 78 | ] 79 | } 80 | ``` 81 | ==== id 82 | `required, type: string` 83 | 84 | Unique identifier of the rule. The id is part of the warning message when the rule is violated. 85 | 86 | ==== appliesTo 87 | `required, type: enum[]` 88 | 89 | An array of file types that should be checked against the rule. Values are: 90 | 91 | [horizontal] 92 | CMakeLists:: CMakeLists.txt files that do not define targets. Usually these are the top-level file and 93 | files that exist to recurse deeper into a directory tree. 94 | TargetCMakeLists:: CMakeLists.txt files that define target(s). 95 | CMakeModule:: A CMake module with file extension `.cmake`. 96 | 97 | ==== name 98 | `required, type: string` 99 | 100 | A short description of the rule. 101 | 102 | ==== enabled 103 | `required, type: boolean` 104 | 105 | Can be used to disable rule checks without removing them from the configuration. 106 | 107 | ==== severity 108 | `optional, type: enum, default: warning` 109 | 110 | One of `info`, `warning`, `error`. The severity is part of the warning output and recognized by e.g. 111 | the Jenkins warnings plugin. It can be used to fine-tune rules e.g. errors could result in a build failure, 112 | warnings in unstable builds and info does not affect the build at all. 113 | 114 | An important use case is the introduction of new warnings. Usually these should not break existing builds. 115 | Instead they can be introduced on info or warning severity. At some point in time when their number is stable, 116 | the severity can be raised. 117 | 118 | ==== checks 119 | `required, type: check[]` 120 | 121 | All checks the rule consists of. The rule is considered as passed for a file when all checks of the rule pass. 122 | A check object consists of the following values: 123 | 124 | ===== id 125 | `required, type: string` 126 | 127 | The identifier of the check, see the list of link:Checks.adoc[available checks]. 128 | 129 | ===== config 130 | `required, type: object` 131 | 132 | Parameters for the specific check, see link:Checks.adoc[checker documentation]. 133 | -------------------------------------------------------------------------------- /package-lock.json:
