Returns the module resolution cache used by a provided resolveModuleNames implementation so that any non-name module resolution operations (eg, package.json lookup) can reuse it

getParsedCommandLine

abstract external val getParsedCommandLine: (fileName: String) -> ParsedCommandLine??

hasInvalidatedResolutions

abstract external val hasInvalidatedResolutions: (Path) -> Boolean?

If provided along with custom resolveModuleNames or resolveTypeReferenceDirectives, used to determine if unchanged file path needs to re-resolve modules/type reference directives

jsDocParsingMode

abstract external var jsDocParsingMode: JSDocParsingMode?

readDirectory

abstract external val readDirectory: (path: String, ReadonlyArray<String>?, ReadonlyArray<String>?, ReadonlyArray<String>?, depth: Double?) -> ReadonlyArray<String>?

If provided, used to cache and handle directory structure modifications

realpath

abstract external val realpath: (path: String) -> String?

Symbol links resolution

reportDiagnostic

abstract external var reportDiagnostic: DiagnosticReporter

reportSolutionBuilderStatus

abstract external var reportSolutionBuilderStatus: DiagnosticReporter

resolveModuleNameLiterals

abstract external val resolveModuleNameLiterals: (ReadonlyArray<StringLiteralLike>, containingFile: String, redirectedReference: ResolvedProjectReference?, options: CompilerOptions, containingSourceFile: SourceFile, ReadonlyArray<StringLiteralLike>?) -> ReadonlyArray<ResolvedModuleWithFailedLookupLocations>?

resolveModuleNames

abstract external val resolveModuleNames: (ReadonlyArray<String>, containingFile: String, ReadonlyArray<String>?, redirectedReference: ResolvedProjectReference?, options: CompilerOptions, containingSourceFile: SourceFile?) -> ReadonlyArray<ResolvedModule?>?

resolveTypeReferenceDirectiveReferences

abstract external val resolveTypeReferenceDirectiveReferences: Function<Any?>?

resolveTypeReferenceDirectives

abstract external val resolveTypeReferenceDirectives: (typeReferenceDirectiveNames: Any, containingFile: String, redirectedReference: ResolvedProjectReference?, options: CompilerOptions, ResolutionMode) -> ReadonlyArray<ResolvedTypeReferenceDirective?>?

trace

abstract external val trace: (s: String) -> Unit?

If provided would be used to write log about compilation

writeFile

abstract external val writeFile: (path: String, data: String, writeByteOrderMark: Boolean?) -> Unit?

Should provide create directory and writeFile if done of invalidatedProjects is not invoked with writeFileCallback

Functions

deleteFile

abstract external fun deleteFile(fileName: String)

fileExists

abstract external fun fileExists(path: String): Boolean

Use to check file presence for source files and if resolveModuleNames is not provided (complier is in charge of module resolution) then module files as well

getCurrentDirectory

abstract external fun getCurrentDirectory(): String

getDefaultLibFileName

abstract external fun getDefaultLibFileName(options: CompilerOptions): String

getModifiedTime

abstract external fun getModifiedTime(fileName: String): Date?

getNewLine

abstract external fun getNewLine(): String

readFile

abstract external fun readFile(path: String, encoding: String = definedExternally): String?

Use to read file text for source files and if resolveModuleNames is not provided (complier is in charge of module resolution) then module files as well

setModifiedTime

abstract external fun setModifiedTime(fileName: String, date: Date)

useCaseSensitiveFileNames

abstract external fun useCaseSensitiveFileNames(): Boolean
