If this setting is specified then non-relative - * names will be resolved relative to baseUrl: i.e. if baseUrl is '/a/b' then candidate location to resolve module name 'c/d' will - * be '/a/b/c/d' - * - paths - this setting can only be used when baseUrl is specified. allows to tune how non-relative module names - * will be resolved based on the content of the module name. - * Structure of 'paths' compiler options - * 'paths': { - * pattern-1: [...substitutions], - * pattern-2: [...substitutions], - * ... - * pattern-n: [...substitutions] - * } - * Pattern here is a string that can contain zero or one '*' character. During module resolution module name will be matched against - * all patterns in the list. Matching for patterns that don't contain '*' means that module name must be equal to pattern respecting the case. - * If pattern contains '*' then to match pattern "*" module name must start with the and end with . - * denotes part of the module name between and . - * If module name can be matches with multiple patterns then pattern with the longest prefix will be picked. - * After selecting pattern we'll use list of substitutions to get candidate locations of the module and the try to load module - * from the candidate location. - * Substitution is a string that can contain zero or one '*'. To get candidate location from substitution we'll pick every - * substitution in the list and replace '*' with string. If candidate location is not rooted it - * will be converted to absolute using baseUrl. - * For example: - * baseUrl: /a/b/c - * "paths": { - * // match all module names - * "*": [ - * "*", // use matched name as is, - * // will be looked as /a/b/c/ - * - * "folder1/*" // substitution will convert matched name to 'folder1/', - * // since it is not rooted then final candidate location will be /a/b/c/folder1/ - * ], - * // match module names that start with 'components/' - * "components/*": [ "/root/components/*" ] // substitution will convert /components/folder1/ to '/root/components/folder1/', - * // it is rooted so it will be final candidate location - * } - * - * 'rootDirs' allows the project to be spreaded across multiple locations and resolve modules with relative names as if - * they were in the same location. For example lets say there are two files - * '/local/src/content/file1.ts' - * '/shared/components/contracts/src/content/protocols/file2.ts' - * After bundling content of '/shared/components/contracts/src' will be merged with '/local/src' so - * if file1 has the following import 'import {x} from "./protocols/file2"' it will be resolved successfully in runtime. - * 'rootDirs' provides the way to tell compiler that in order to get the whole project it should behave as if content of all - * root dirs were merged together. - * I.e. for the example above 'rootDirs' will have two entries: [ '/local/src', '/shared/components/contracts/src' ]. - * Compiler will first convert './protocols/file2' into absolute path relative to the location of containing file: - * '/local/src/content/protocols/file2' and try to load it - failure. - * Then it will search 'rootDirs' looking for a longest matching prefix of this absolute path and if such prefix is found - absolute path will - * be converted to a path relative to found rootDir entry './content/protocols/file2' (*). As a last step compiler will check all remaining - * entries in 'rootDirs', use them to build absolute path out of (*) and try to resolve module from this location. - */ - function tryLoadModuleUsingOptionalResolutionSettings(extensions, moduleName, containingDirectory, loader, failedLookupLocations, state) { - if (moduleHasNonRelativeName(moduleName)) { - return tryLoadModuleUsingBaseUrl(extensions, moduleName, loader, failedLookupLocations, state); - } - else { - return tryLoadModuleUsingRootDirs(extensions, moduleName, containingDirectory, loader, failedLookupLocations, state); - } - } - function tryLoadModuleUsingRootDirs(extensions, moduleName, containingDirectory, loader, failedLookupLocations, state) { - if (!state.compilerOptions.rootDirs) { - return undefined; - } - if (state.traceEnabled) { - trace(state.host, ts.Diagnostics.rootDirs_option_is_set_using_it_to_resolve_relative_module_name_0, moduleName); - } - var candidate = ts.normalizePath(ts.combinePaths(containingDirectory, moduleName)); - var matchedRootDir; - var matchedNormalizedPrefix; - for (var _i = 0, _a = state.compilerOptions.rootDirs; _i < _a.length; _i++) { - var rootDir = _a[_i]; - // rootDirs are expected to be absolute - // in case of tsconfig.json this will happen automatically - compiler will expand relative names - // using location of tsconfig.json as base location - var normalizedRoot = ts.normalizePath(rootDir); - if (!ts.endsWith(normalizedRoot, ts.directorySeparator)) { - normalizedRoot += ts.directorySeparator; - } - var isLongestMatchingPrefix = ts.startsWith(candidate, normalizedRoot) && - (matchedNormalizedPrefix === undefined || matchedNormalizedPrefix.length < normalizedRoot.length); - if (state.traceEnabled) { - trace(state.host, ts.Diagnostics.Checking_if_0_is_the_longest_matching_prefix_for_1_2, normalizedRoot, candidate, isLongestMatchingPrefix); - } - if (isLongestMatchingPrefix) { - matchedNormalizedPrefix = normalizedRoot; - matchedRootDir = rootDir; - } - } - if (matchedNormalizedPrefix) { - if (state.traceEnabled) { - trace(state.host, ts.Diagnostics.Longest_matching_prefix_for_0_is_1, candidate, matchedNormalizedPrefix); - } - var suffix = candidate.substr(matchedNormalizedPrefix.length); - // first - try to load from a initial location - if (state.traceEnabled) { - trace(state.host, ts.Diagnostics.Loading_0_from_the_root_dir_1_candidate_location_2, suffix, matchedNormalizedPrefix, candidate); - } - var resolvedFileName = loader(extensions, candidate, failedLookupLocations, !directoryProbablyExists(containingDirectory, state.host), state); - if (resolvedFileName) { - return resolvedFileName; - } - if (state.traceEnabled) { - trace(state.host, ts.Diagnostics.Trying_other_entries_in_rootDirs); - } - // then try to resolve using remaining entries in rootDirs - for (var _b = 0, _c = state.compilerOptions.rootDirs; _b < _c.length; _b++) { - var rootDir = _c[_b]; - if (rootDir === matchedRootDir) { - // skip the initially matched entry - continue; - } - var candidate_1 = ts.combinePaths(ts.normalizePath(rootDir), suffix); - if (state.traceEnabled) { - trace(state.host, ts.Diagnostics.Loading_0_from_the_root_dir_1_candidate_location_2, suffix, rootDir, candidate_1); - } - var baseDirectory = ts.getDirectoryPath(candidate_1); - var resolvedFileName_1 = loader(extensions, candidate_1, failedLookupLocations, !directoryProbablyExists(baseDirectory, state.host), state); - if (resolvedFileName_1) { - return resolvedFileName_1; - } - } - if (state.traceEnabled) { - trace(state.host, ts.Diagnostics.Module_resolution_using_rootDirs_has_failed); - } - } - return undefined; - } - function tryLoadModuleUsingBaseUrl(extensions, moduleName, loader, failedLookupLocations, state) { - if (!state.compilerOptions.baseUrl) { - return undefined; - } - if (state.traceEnabled) { - trace(state.host, ts.Diagnostics.baseUrl_option_is_set_to_0_using_this_value_to_resolve_non_relative_module_name_1, state.compilerOptions.baseUrl, moduleName); - } - // string is for exact match - var matchedPattern = undefined; - if (state.compilerOptions.paths) { - if (state.traceEnabled) { - trace(state.host, ts.Diagnostics.paths_option_is_specified_looking_for_a_pattern_to_match_module_name_0, moduleName); - } - matchedPattern = ts.matchPatternOrExact(ts.getOwnKeys(state.compilerOptions.paths), moduleName); - } - if (matchedPattern) { - var matchedStar_1 = typeof matchedPattern === "string" ?
