[{"name":"Review.FilePattern","comment":" A module for selecting multiple files from the file system\nusing [`glob`] patterns and negated patterns.\n\n    import Review.FilePattern as FilePattern\n\n    filePatterns =\n        [ FilePattern.include \"**/*.css\"\n        , FilePattern.exclude \"**/*-test.css\"\n        , FilePattern.excludeDirectory \"ignore-folder/\"\n        ]\n\nSome `elm-review` APIs require a `List FilePattern` as an argument to figure out a list of files to match or not match.\n\nThis list works similar like [`.gitignore`] files: any matching file excluded by a previous pattern will become included again.\nFiles that are in [excluded directories](#excludeDirectory) are ignored entirely.\n\nA file pattern is always relative to the project's `elm.json` file, is case-sensitive,\nand should be written in the Unix style (`src/Some/File.elm`, not `src\\Some\\File.elm`).\n\n@docs FilePattern\n@docs include, exclude, excludeDirectory\n\n\n## Supported patterns\n\nThe supported patterns are the following:\n\n  - `?` matches an unknown single character (except `/`). \"a?c\" would match \"abc\" or \"a5c\", but not \"ac\".\n  - `*` matches any number of unknown characters (except `/`). \"some-\\*.txt\" would match \"some-file.txt\" and \"some-other-file.txt\", but not \"other-file.txt\" or \"some-folder/file.txt\".\n  - `**` matches any number of sub-directories. \"projects/**/README.md\" would match \"projects/README.md\", \"projects/a/README.md\" and \"projects/a/b/README.md\". If you desire to include all files in a folder, then you need to end the pattern with `/**/*` (eg \"projects/**/\\*\" or \"projects/\\*\\*/\\*.md\").\n  - `[characters]` matches one of the specified characters. `a[bc]d` would match \"abc\" and \"acd\", but not \"axd\".\n  - `[^characters]` matches anything that is not one of the specified characters. `a[^bc]d` would match \"axc\", but not \"abd\" or \"acd\".\n  - `[character1-character2]` matches a range of characters. `a[a-z]d` would match \"aac\" and \"azd\", but not \"a5d\".\n  - `{string1|string2}` matches one of the provided strings. \"file.{js|ts}\" would match \"file.js\" and \"file.ts\" but not \"file.md\".\n\n\n## Using FilePattern\n\n@docs Summary, compact, match\n@docs toStrings\n\n[`glob`]: https://en.wikipedia.org/wiki/Glob_%28programming%29\n[`.gitignore`]: https://git-scm.com/docs/gitignore#_pattern_format\n\n","unions":[{"name":"FilePattern","comment":" A pattern to included or exclude files from a selection.\n","args":[],"cases":[]},{"name":"Summary","comment":" Compiled version of a list of `FilePattern`s.\nThis is done to have good performance.\n","args":[],"cases":[]}],"aliases":[],"values":[{"name":"compact","comment":" Compile a list of `FilePattern`s.\nThis is done to have good performance.\n","type":"List.List Review.FilePattern.FilePattern -> Result.Result (List.List String.String) Review.FilePattern.Summary"},{"name":"exclude","comment":" Create a `FilePattern` that excludes files that match a Glob-like pattern.\n\n    [ FilePattern.include \"**/*.css\"\n    , FilePattern.exclude \"exception.css\"\n    ]\n\nFiles that get excluded this way can be re-included through `FilePattern.include`.\n\n    [ FilePattern.include \"**/*.css\"\n    , FilePattern.exclude \"exception-*.css\"\n    , FilePattern.include \"exception-among-exceptions.css\"\n    ]\n\n","type":"String.String -> Review.FilePattern.FilePattern"},{"name":"excludeDirectory","comment":" Create a `FilePattern` that excludes a whole directory.\nFiles that get excluded this way can't be re-included.\n\n    [ FilePattern.include \"**/*.css\"\n    , FilePattern.excludeDirectory \"build/\"\n    ]\n\n","type":"String.String -> Review.FilePattern.FilePattern"},{"name":"include","comment":" Create a `FilePattern` that includes files that match a Glob-like pattern.\n\n    [ FilePattern.include \"CHANGELOG.md\"\n    , FilePattern.include \"src/**/*.elm\"\n    , FilePattern.include \"*.css\"\n    ]\n\n","type":"String.String -> Review.FilePattern.FilePattern"},{"name":"match","comment":" Check if a file path matches file patterns.\n","type":"{ includeByDefault : Basics.Bool } -> Review.FilePattern.Summary -> String.String -> Basics.Bool"},{"name":"toStrings","comment":" Stringify the file patterns in a way that is easily understandable by a JavaScript Glob-like API.\n","type":"Review.FilePattern.Summary -> { files : List.List { pattern : String.String, included : Basics.Bool }, excludedDirectories : List.List String.String }"}],"binops":[]},{"name":"Review.Fix","comment":" Tools to write automatic error fixes.\n\nWhen creating a [`Review.Rule.Error`](./Review-Rule#Error), you can provide an automatic\nfix for the error using [`Review.Rule.errorWithFix`](./Review-Rule#errorWithFix)\nor other functions that end with \"withFix\" so that the user doesn't need to fix\nthe problem themselves.\n\nIn the [CLI](https://github.com/jfmengels/node-elm-review), the user can ask to fix the errors automatically, and in doing so,\nthey will be presented by a fix which they can accept or refuse. If the fix gets\nrefused, then the next fixable error will be presented. Otherwise, if the fix\ngets accepted, the file will be applied and the fixed file content get analyzed\nagain by the different rules in the user's configuration, and then another fix\nwill be presented. When there are no more fixable errors, the remaining errors\nwill be reported, just like when the user doesn't request errors to be automatically\nfixed.\n\nIn summary, errors will be presented one by one and the user will validate them.\nThe [CLI] also proposes an option to fix all the errors, which applies each fix\none by one and then asks the user to confirm the cumulated fix.\n\n\n# Guidelines\n\nAn automatic fix, when applied, should resolve the reported error completely.\nThis means that when the automatic fix is applied, the user should not have to\nthink about the error anymore or have to do additional work.\n\nImagine if the user applies a lot of automatic fixes all at once. We don't want them to have to\nremember having to do something, otherwise we may have just offloaded a lot of\nwork that they may forget to do. In that case, it is better not to provide a fix\nat all, so that they keep a reminder and the details of how to fix the problem.\n\nAn automatic fix should resolve only the reported error, not try to fix other\npotential errors. By only fixing one error at a time, the fix will be easier for\nthe user to digest and understand. The file will be re-reviewed when the fix is\napplied, and then another error can fix that one.\n\n\n# When (not) to provide an automatic fix?\n\nFor users, having an automatic fix always feels like a nice-to-have and they may\nrequest you to provide some, but they are not mandatory, and in some cases, it\nis better not to have any.\n\n\n## Reasons not to provide an automatic fix\n\n\n### A complete automatic fix is not possible\n\nSometimes, just by going through the whole file, you are missing some of the\ninformation needed to generate the right fix. Instead of providing a partial or\npotentially incorrect fix, it would be better to provide more details, hints or\nsuggestions.\n\n\n### The fix would result in a compiler error\n\nAn automatic fix should not cause changes that would break the file or the\nproject. In some cases, we can detect that the [fix will break things](#Problem),\nlike if the result of the fix is invalid Elm code (as in resulting in a parsing\nerror), but ultimately we can't detect that the project will still compile after\nthe fix is applied.\n\nUsers are notified that an automatic fix is available. For performance reasons,\nwe only check that a fix is valid before presenting it to the user and ignore it\nif it turns out to be invalid. This means that the user will be disappointed or\nconfused when the error ends up not being enforced. The only way we have to\nprevent this is to write tests, as fixes are applied in tests.\n\n\n### The user should learn about the problem and how to solve it\n\nSometimes problems are learning opportunities, and it is worth having the user\nspend some time reading through the details of the error and trying several\nalternatives in order to understand the problem and the tradeoffs of the\nsolutions. You can guide them by using great error details!\n\n\n## Reasons to provide an automatic fix\n\nThe reasons to provide an automatic fix are basically the opposite of the\nreasons not to provide an automatic fix:\n\n  - We know how to fix the problem completely and accurately\n  - The task is menial and the user will not learn much by fixing the error\n    themselves\n\n\n# Strategies for writing automatic fixes effectively\n\n\n### Write a lot of tests\n\nAutomatic fixes are more error-prone than rules, especially since we may work\nwith re-writing ports of the code, for which the AST does not provide the\ncurrent formatting of a file (there is no information about spacing,\nline-breaks, ...). I suggest writing a lot of tests, and especially write tests\nwhere the formatting of the original file is a bit odd, as you may for instance\nunknowingly attempt to delete characters next to the thing you wanted to remove.\n\n\n### Store ranges in the context if necessary\n\nFixes work with ranges or position. If the context of a different element is not\navailable in the scope of where you create the error, then you should store it\nin the context of your rule.\n\n\n# Creating a fix\n\n@docs Fix, removeRange, replaceRangeBy, insertAt\n\n\n# Applying fixes\n\n@docs FixResult, Problem, fix\n\n[CLI]: https://github.com/jfmengels/node-elm-review\n\n\n# Tooling\n\n@docs toRecord\n\n","unions":[{"name":"FixResult","comment":" Represents the result of having applied a list of fixes to a source code.\n","args":[],"cases":[["Successful",["String.String"]],["Errored",["Review.Fix.Problem"]]]},{"name":"Problem","comment":" Represents a problem that may have occurred when attempting to apply a list\nof fixes.\n","args":[],"cases":[["Unchanged",[]],["SourceCodeIsNotValid",["String.String"]],["HasCollisionsInFixRanges",[]]]}],"aliases":[{"name":"Fix","comment":" Represents (part of a) fix that will be applied to a file's source code in order to\nautomatically fix a review error.\n","args":[],"type":"Review.Fix.Internal.Fix"}],"values":[{"name":"fix","comment":" Apply the changes on the source code.\n","type":"Review.Error.Target -> List.List Review.Fix.Fix -> String.String -> Review.Fix.FixResult"},{"name":"insertAt","comment":" Insert some code at the given position.\n","type":"{ row : Basics.Int, column : Basics.Int } -> String.String -> Review.Fix.Fix"},{"name":"removeRange","comment":" Remove the code in between a range.\n","type":"Elm.Syntax.Range.Range -> Review.Fix.Fix"},{"name":"replaceRangeBy","comment":" Replace the code in between a range by some other code.\n","type":"Elm.Syntax.Range.Range -> String.String -> Review.Fix.Fix"},{"name":"toRecord","comment":" Describe a fix as a range to replace by something else.\n\nThis is meant for external tooling.

This will create a new package that will help you use the best practices and give you helpful tools like easy auto-publishing. More information is available in the maintenance file generated along with it.\n\nIf you want to **add/create a rule** for the package or for your local configuration, then I recommend using `elm-review new-rule`, which will create a source and test file which you can use as a starting point. For packages, it will add the rule everywhere it should be present (`exposed-modules`, README, ...).\n\n\n# How does it work?\n\n`elm-review` reads the modules, `elm.json`, dependencies and `README.md` from your project,\nand turns each module into an [Abstract Syntax Tree (AST)](https://en.wikipedia.org/wiki/Abstract_syntax_tree),\na tree-like structure which represents your source code, using the\n[`elm-syntax` package](https://package.elm-lang.org/packages/stil4m/elm-syntax/7.2.1/).\n\n`elm-review` then feeds all this data into `review rules`, that traverse them to report problems.\nThe way that review rules go through the data depends on whether it is a [module rule](#creating-a-module-rule) or a [project rule](#creating-a-project-rule).\n\n`elm-review` relies on the [`elm-syntax` package](https://package.elm-lang.org/packages/stil4m/elm-syntax/7.2.1/),\nand all the node types you'll see will be coming from there. You are likely to\nneed to have the documentation for that package open when writing a rule.\n\nThere are plenty of examples in this documentation, and you can also look at the\nsource code of existing rules to better grasp how they work.\n\n**NOTE**: These examples are only here to showcase how to write rules and how a function can\nbe used. They are not necessarily good rules to enforce. See the\n[section on whether to write a rule](./#when-to-write-or-enable-a-rule) for more on that.\nEven if you think they are good ideas to enforce, they are often not complete, as there are other\npatterns you would want to forbid, but that are not handled by the example.\n\n\n# What makes a good rule\n\nApart from the rationale on [whether a rule should be written](./#when-to-write-or-enable-a-rule),\nhere are a few tips on what makes a rule helpful.\n\nA review rule is an automated communication tool which sends messages to\ndevelopers who have written patterns your rule wishes to prevent. As all\ncommunication, the message is important.\n\n\n## A good rule name\n\nThe name of the rule (`NoUnusedVariables`, `NoDebug`, ...) should try to convey\nreally quickly what kind of pattern we're dealing with. Ideally, a user who\nencounters this pattern for the first time could guess the problem just from the\nname. And a user who encountered it several times should know how to fix the\nproblem just from the name too.\n\nI recommend having the name of the module containing the rule be the same as the\nrule name. This will make it easier to find the module in the project or on\nthe packages website when trying to get more information.\n\n\n## A helpful error message and details\n\nThe error message should give more information about the problem. It is split\ninto two parts:\n\n  - The `message`: A short sentence that describes the forbidden pattern. A user\n    that has encountered this error multiple times should know exactly what to do.\n    Example: \"Function `foo` is never used\". With this information, a user who\n    knows the rule probably knows that a function needs to be removed from the\n    source code, and also knows which one.\n  - The `details`: All the additional information that can be useful to the\n    user, such as the rationale behind forbidding the pattern, and suggestions\n    for a solution or alternative.\n\nWhen writing the error message that the user will see, try to make them be as\nhelpful as the messages the compiler gives you when it encounters a problem.\n\n\n## The smallest section of code that makes sense\n\nWhen creating an error, you need to specify under which section of the code this\nmessage appears. This is where you would see squiggly lines in your editor when\nyou have review or compiler errors.\n\nTo make the error easier to spot, it is best to make this section as small as\npossible, as long as that makes sense. For instance, in a rule that would forbid\n`Debug.log`, you would the error to appear under `Debug.log`, not on the whole\nfunction which contains this piece of code.\n\n\n## Good rule documentation\n\nThe rule documentation should give the same information as what you would see in\nthe error message.\n\nIf published in a package, the rule documentation should explain when not to\nenable the rule in the user's review configuration. For instance, for a rule that\nmakes sure that a package is publishable by ensuring that all docs are valid,\nthe rule might say something along the lines of \"If you are writing an\napplication, then you should not use this rule\".\n\nAdditionally, it could give a few examples of patterns that will be reported and\nof patterns that will not be reported, so that users can have a better grasp of\nwhat to expect.\n\n\n# Strategies for writing rules effectively\n\n\n## Use Test-Driven Development\n\nThis package comes with [`Review.Test`](./Review-Test), which works with [`elm-test`](https://github.com/elm-explorations/test).\nI recommend reading through [`the strategies for effective testing`](./Review-Test#strategies-for-effective-testing) before\nstarting writing a rule.\n\n\n## Look at the documentation for [`elm-syntax`](https://package.elm-lang.org/packages/stil4m/elm-syntax/7.2.1/)\n\n`elm-review` is heavily dependent on the types that [`elm-syntax`](https://package.elm-lang.org/packages/stil4m/elm-syntax/7.2.1/)\nprovides. If you don't understand the AST it provides, you will have a hard time\nimplementing the rule you wish to create.\n\n\n# Writing a Rule\n\n@docs Rule\n\n\n## Creating a module rule\n\nA \"module rule\" looks at modules (i.e. files) one by one. When it finishes looking at a module and reporting errors,\nit forgets everything about the module it just analyzed before starting to look at a different module. You should create one of these if you\ndo not need to know the contents of a different module in the project, such as what functions are exposed.\nIf you do need that information, you should create a [project rule](#creating-a-project-rule).\n\nIf you are new to writing rules, I would recommend learning how to build a module rule first, as they are in practice a\nsimpler version of project rules.\n\nThe traversal of a module rule is the following:\n\n  - Read project-related info (only collect data in the context in these steps)\n      - The `elm.json` file, visited by [`withElmJsonModuleVisitor`](#withElmJsonModuleVisitor)\n      - The `README.md` file, visited by [`withReadmeModuleVisitor`](#withReadmeModuleVisitor)\n      - Extra files that are not analyzed by default, visited by [`withExtraFilesModuleVisitor`](#withExtraFilesModuleVisitor)\n      - The definition for dependencies, visited by [`withDirectDependenciesModuleVisitor`](#withDirectDependenciesModuleVisitor) and [`withDependenciesModuleVisitor`](#withDependenciesModuleVisitor)\n  - Visit the Elm module (in the following order)\n      - The module definition, visited by [`withSimpleModuleDefinitionVisitor`](#withSimpleModuleDefinitionVisitor) and [`withModuleDefinitionVisitor`](#withModuleDefinitionVisitor)\n      - The module documentation, visited by [`withModuleDocumentationVisitor`](#withModuleDocumentationVisitor)\n      - The module's list of comments, visited by [`withSimpleCommentsVisitor`](#withSimpleCommentsVisitor) and [`withCommentsVisitor`](#withCommentsVisitor)\n      - Each import, visited by [`withSimpleImportVisitor`](#withSimpleImportVisitor) and [`withImportVisitor`](#withImportVisitor)\n      - The list of declarations, visited by [`withDeclarationListVisitor`](#withDeclarationListVisitor)\n      - Each declaration, visited in the following order:\n          - [`withSimpleDeclarationVisitor`](#withSimpleDeclarationVisitor) and [`withDeclarationEnterVisitor`](#withDeclarationEnterVisitor)\n          - The expression contained in the declaration will be visited recursively by [`withSimpleExpressionVisitor`](#withSimpleExpressionVisitor), [`withExpressionEnterVisitor`](#withExpressionEnterVisitor) and [`withExpressionExitVisitor`](#withExpressionExitVisitor).\n          - [`withDeclarationExitVisitor`](#withDeclarationExitVisitor)\n      - A final evaluation is made when the module has fully been visited, using [`withFinalModuleEvaluation`](#withFinalModuleEvaluation)\n\nEvaluating/visiting a node means two things:\n\n  - Detecting patterns and reporting errors\n  - Collecting data in a \"context\" (called `moduleContext` for module rules) to have more information available in a later\n    node evaluation. You can only use the context and update it with \"non-simple with\\*\" visitor functions.\n    I recommend using the \"simple with\\*\" visitor functions if you don't need to do either, as they are simpler to use\n\n@docs ModuleRuleSchema, newModuleRuleSchema, fromModuleRuleSchema\n\n\n## Builder functions without context\n\n@docs withSimpleModuleDefinitionVisitor, withSimpleCommentsVisitor, withSimpleImportVisitor, withSimpleDeclarationVisitor, withSimpleExpressionVisitor\n\n\n## Builder functions with context\n\n@docs newModuleRuleSchemaUsingContextCreator\n@docs withModuleDefinitionVisitor\n@docs withModuleDocumentationVisitor\n@docs withCommentsVisitor\n@docs withImportVisitor\n@docs Direction, withDeclarationEnterVisitor, withDeclarationExitVisitor, withDeclarationVisitor, withDeclarationListVisitor\n@docs withExpressionEnterVisitor, withExpressionExitVisitor, withExpressionVisitor\n@docs withCaseBranchEnterVisitor, withCaseBranchExitVisitor\n@docs withLetDeclarationEnterVisitor, withLetDeclarationExitVisitor\n@docs providesFixesForModuleRule\n@docs withFinalModuleEvaluation\n\n\n## Builder functions to analyze the project's data\n\n@docs withElmJsonModuleVisitor, withReadmeModuleVisitor, withDirectDependenciesModuleVisitor, withDependenciesModuleVisitor\n@docs withExtraFilesModuleVisitor\n\n\n## Creating a project rule\n\nProject rules can look at the global picture of an Elm project. Contrary to module\nrules, which forget everything about the module they were looking at when going from\none module to another, project rules can retain information about previously\nanalyzed modules, and use it to report errors when analyzing a different module or\nafter all modules have been visited.\n\nProject rules can also report errors in the `elm.json` or the `README.md` files.\n\nIf you are new to writing rules, I would recommend learning [how to build a module rule](#creating-a-module-rule)\nfirst, as they are in practice a simpler version of project rules.\n\n@docs ProjectRuleSchema, newProjectRuleSchema, fromProjectRuleSchema, withModuleVisitor, withModuleContext, withModuleContextUsingContextCreator, withElmJsonProjectVisitor, withReadmeProjectVisitor, withDirectDependenciesProjectVisitor, withDependenciesProjectVisitor, withFinalProjectEvaluation, withExtraFilesProjectVisitor, withContextFromImportedModules\n@docs providesFixesForProjectRule\n\n\n## Requesting more information\n\n@docs ContextCreator, initContextCreator, withModuleName, withModuleNameNode, withIsInSourceDirectories, withFilePath, withIsFileIgnored, withModuleNameLookupTable, withModuleKey, withSourceCodeExtractor, withFullAst, withModuleDocumentation\n\n\n### Requesting more information (DEPRECATED)\n\n@docs Metadata, withMetadata, moduleNameFromMetadata, moduleNameNodeFromMetadata, isInSourceDirectories\n\n\n## Errors\n\n@docs Error, error, errorWithFix, ModuleKey, errorForModule, errorForModuleWithFix\n@docs ElmJsonKey, errorForElmJson, errorForElmJsonWithFix\n@docs ReadmeKey, errorForReadme, errorForReadmeWithFix\n@docs ExtraFileKey, errorForExtraFile, errorForExtraFileWithFix\n@docs globalError, configurationError\n@docs ReviewError, errorRuleName, errorMessage, errorDetails, errorRange, errorFilePath, errorTarget, errorFixes, errorFixFailure\n\n\n## Configuring exceptions\n\nThere are situations where you don't want review rules to report errors:\n\n1.  You copied and updated over an external library because one of your needs wasn't met, and you don't want to modify it more than necessary.\n2.  Your project contains generated source code, over which you have no control or for which you do not care that some rules are enforced (like the reports of unused variables).\n3.  You want to introduce a rule progressively, because there are too many errors in the project for you to fix in one go. You can then ignore the parts of the project where the problem has not yet been solved, and fix them as you go.\n4.  You wrote a rule that is very specific and should only be applied to a portion of your code.\n5.  You wish to disable some rules for tests files (or enable some only for tests).\n\nYou can use the following functions to ignore errors in directories or files, or only report errors found in specific directories or files.\n\n**NOTE**: Even though they can be used to disable any errors, I **strongly recommend against**\ndoing so if you are not in the situations listed above. I highly recommend you\nleave a comment explaining the reason why you use these functions, or to\ncommunicate with your colleagues if you see them adding exceptions without\nreason or seemingly inappropriately.\n\n@docs ignoreErrorsForDirectories, ignoreErrorsForFiles, filterErrorsForFiles\n\n\n## Extract information\n\nAs you might have seen so far, `elm-review` has quite a nice way of traversing the files of a project and collecting data.\n\nWhile you have only seen the tool be used to report errors, you can also use it to extract information from\nthe codebase. You can use this to gain insight into your codebase, or provide information to other tools to enable\npowerful integrations.\n\nYou can read more about how to use this in [_Extract information_ in the README](./#extract-information), and you can\nfind the tools to extract data below.\n\n@docs withDataExtractor, preventExtract\n\n\n# Running rules\n\n@docs reviewV3, reviewV2, review, ProjectData, ruleName, ruleProvidesFixes, ruleKnowsAboutIgnoredFiles, ruleRequestedFiles, withRuleId, getConfigurationError\n\n\n# Internals\n\n@docs Required, Forbidden\n\n","unions":[{"name":"ContextCreator","comment":" Create a module context from a project context or the other way around.\nUse functions like [`withModuleName`](#withModuleName) to request more information.\n","args":["from","to"],"cases":[]},{"name":"Direction","comment":" **@deprecated**\n\nThis is used in [`withDeclarationVisitor`](#withDeclarationVisitor) and [`withDeclarationVisitor`](#withDeclarationVisitor),\nwhich are deprecated and will be removed in the next major version.

We do this because in most\nproject rules you won't need all the data from the `projectContext` to analyze a\nmodule, and some data from the module context will not make sense inside the\nproject context.\n\nWhen visiting modules, `elm-review` follows a kind of map-reduce architecture.\nThe idea is the following: it starts with an initial `projectContext` and collects data\nfrom project-related files into it. Then, it visits every module with an initial\n`moduleContext` derived from a `projectContext`. At the end of a module's visit,\nthe final `moduleContext` will be transformed (\"map\") to a `projectContext`.\nAll or some of the `projectContext`s will then be folded into a single one,\nbefore being used in the [final project evaluation] or to compute another module's\ninitial `moduleContext`.\n\nThis will help make the result of the review as consistent as possible, by\nhaving the results be independent of the order the modules are visited. This also\ngives internal guarantees as to what needs to be re-computed when re-analyzing\nthe project, which leads to huge performance boosts in watch mode or after fixes\nhave been applied.\n\nThe following sections will explain each function, and will be summarized by an\nexample.\n\n\n### `fromProjectToModule`\n\nThe initial `moduleContext` of the module visitor is computed using `fromProjectToModule`\nfrom a `projectContext`. By default, this `projectContext` will be the result of\nvisiting the project-related files (`elm.json`, `README.md`, ...).\nIf [`withContextFromImportedModules`] was used, then the value will be this last\n`projectContext`, folded with each imported module's resulting `projectContext`,\nusing [`foldProjectContexts`].\n\nThe [`ModuleKey`] will allow you to report errors for this specific module\nusing [`errorForModule`](#errorForModule) from the [final project evaluation] or\nwhile visiting another module. If you plan to do that, you should store this in\nthe `moduleContext`. You can also get it from [`fromModuleToProject`], so choose\nwhat's most convenient.\n\nThe [`Node`] containing the module name is passed for convenience, so you don't\nhave to visit the module definition just to get the module name. Just like what\nit is in [`elm-syntax`](https://package.elm-lang.org/packages/stil4m/elm-syntax/7.2.1/Elm-Syntax-ModuleName),\nthe value will be `[ \"My\", \"Module\" ]` if the module name is `My.Module`.\n\n\n### `fromModuleToProject`\n\nWhen a module has finished being analyzed, the final `moduleContext` will be\nconverted into a `projectContext`, so that it can later be folded with the other\nproject contexts using `foldProjectContexts`. The resulting `projectContext`\nwill be fed into the [final project evaluation] and potentially into\n[`fromProjectToModule`] for modules that import the current one.\n\nSimilarly to `fromProjectToModule`, the [`Node`] containing the module name and\nthe [`ModuleKey`] are passed for convenience, so you don't have to store them in\nthe `moduleContext` only to store them in the `projectContext`.\n\n\n### `foldProjectContexts`\n\nThis function folds two `projectContext` into one. This function requires a few\ntraits to always be true.\n\n  - `projectContext`s should be \"merged\" together, not \"subtracted\". If for instance\n    you want to detect the unused exports of a module, do not remove a declared\n    export when you have found it used. Instead, store and accumulate the declared\n    and used functions (both probably as `Set`s or `Dict`s), and in the final evaluation,\n    filter out the declared functions if they are in the set of used functions.\n  - The order of folding should not matter: `foldProjectContexts b (foldProjectContexts a initial)`\n    should equal `foldProjectContexts a (foldProjectContexts b initial)`.\n    [`List.concat`](https://package.elm-lang.org/packages/elm/core/latest/List#concat).\n  - Folding an element twice into another should give the same result as folding\n    it once. In other words, `foldProjectContexts a (foldProjectContexts a initial)`\n    should equal `foldProjectContexts a initial`. You will likely need to use functions\n    like [`Set.union`](https://package.elm-lang.org/packages/elm/core/latest/Set#union)\n    and [`Dict.union`](https://package.elm-lang.org/packages/elm/core/latest/Dict#union)\n    over addition and functions like\n    [`List.concat`](https://package.elm-lang.org/packages/elm/core/latest/List#concat).\n\nIt is not necessary for the function to be commutative (i.e. that\n`foldProjectContexts a b` equals `foldProjectContexts b a`). It is fine to take\nthe value from the \"initial\" `projectContext` and ignore the other one, especially\nfor data computed in the project-related visitors (for which you will probably\ndefine a dummy value in the `fromModuleToProject` function). If it helps, imagine\nthat the second argument is the initial `projectContext`, or that it is an accumulator\njust like in `List.foldl`.\n\n\n### Summary example - Reporting unused exported

You should not add support for new patterns, as you will\n    want to write tests for those first.\n\nThen repeat for every pattern you wish to handle.\n\n\n## Have a good title\n\nA good test title explains\n\n  - what is tested - Probably the rule, but making it explicit\n    in a [`describe`](https://package.elm-lang.org/packages/elm-explorations/test/latest/Test#describe)\n    might improve your test report. Or maybe you are testing a sub-part of the rule,\n    and you can name it explicitly.\n  - what should happen: (not) reporting an error, fix <something> by <doing something>, ...\n  - when: what is the situation that this test sets up?\n\nIdeally, by only reading through the test titles, someone else should be able to\nrewrite the rule you are testing.\n\n\n## What should you test?\n\nYou should test the scenarios where you expect the rule to report something. At\nthe same time, you should also test when it shouldn't. I encourage writing tests\nto make sure that things that are similar to what you want to report are not\nreported.\n\nFor instance, if you wish to report uses of variables named `foo`, write a test\nthat ensures that the use of variables named differently does not get reported.\n\nTests are pretty cheap, and in the case of rules, it is probably better to have\ntoo many tests rather than too few, since the behavior of a rule rarely changes\ndrastically.\n\n\n# Design goals\n\nIf you are interested, you can read\n[the design goals](https://github.com/jfmengels/elm-review/blob/master/documentation/design/test-module.md)\nfor this module.\n\n\n# Running tests\n\n@docs ReviewResult, run, runWithProjectData, runOnModules, runOnModulesWithProjectData\n\n\n# Making assertions\n\n@docs ExpectedError, expectNoErrors, expectErrors, error, atExactly, whenFixed, expectErrorsForModules, expectErrorsForElmJson, expectErrorsForReadme, expectErrorsForExtraFile\n@docs expectGlobalErrors\n@docs expectConfigurationError\n@docs expectDataExtract\n@docs ignoredFilesImpactResults\n\n\n## Composite assertions\n\n@docs expect, ReviewExpectation\n@docs moduleErrors, globalErrors, elmJsonErrors, readmeErrors, extraFileErrors, dataExtract\n\n\n# Deprecated\n\n@docs expectGlobalAndLocalErrors, expectGlobalAndModuleErrors\n\n","unions":[{"name":"ExpectedError","comment":" An expectation for an error.
