For example: - // - // SingleNameBinding[Yield,GeneratorParameter] - // [+GeneratorParameter]BindingIdentifier[Yield] Initializer[In]opt - // [~GeneratorParameter]BindingIdentifier[?Yield]Initializer[In, ?Yield]opt - // - // Here this is saying that if the GeneratorParameter context flag is set, that we should - // explicitly set the 'yield' context flag to false before calling into the BindingIdentifier - // and we should explicitly unset the 'yield' context flag before calling into the Initializer. - // production.

These context flags are naturally stored and restored through normal recursive - // descent parsing and unwinding. - var contextFlags; - // Whether or not we've had a parse error since creating the last AST node.

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' (*).
