Variable StringFoldConst

Type Declaration

• Readonlycall: (this: void, args: BuiltInEvalHandlerArgs) => Value

  What a string call amounts to; see resolveAsStringFn.

• Readonlyfns: {
      basename: {
          fold: (path: string) => string;
          params: readonly ["path"];
          pkg: Base;
      };
      dirname: {
          fold: (path: string) => string;
          params: readonly ["path"];
          pkg: Base;
      };
      "file.path": {
          defaults: { fsep: "/" };
          fold: (parts: (...)[], fsep: string) => string;
          params: readonly ["...", "fsep"];
          pkg: Base;
      };
      here: {
          fold: (parts: (...)[]) => string;
          params: readonly ["..."];
          pkg: Here;
      };
      nchar: { fold: (s: string) => number; params: readonly ["x"]; pkg: Base };
      paste: {
          defaults: { sep: " " };
          fold: (parts: (...)[], sep: string) => string;
          ignored: readonly ["collapse"];

          fold: (parts: (...)[], sep: string) => string;
          ignored: readonly ["collapse"];
          params: readonly ["...", "sep"];
          pkg: Base;
      };
      tolower: { fold: (s: string) => string; params: readonly ["x"]; pkg: Base };
      toupper: { fold: (s: string) => string; params: readonly ["x"]; pkg: Base };
      trimws: { fold: (s: string) => string; params: readonly ["x"]; pkg: Base };
  }

  every string built-in that is folded, see StringFns

  • Readonlybasename: { fold: (path: string) => string; params: readonly ["path"]; pkg: Base }

    • Readonlyfold: (path: string) => string

    • Readonlyparams: readonly ["path"]

    • Readonlypkg: Base

  • Readonlydirname: { fold: (path: string) => string; params: readonly ["path"]; pkg: Base }

    • Readonlyfold: (path: string) => string

    • Readonlyparams: readonly ["path"]

    • Readonlypkg: Base

  • Readonlyfile.path: {
        defaults: { fsep: "/" };
        fold: (parts: (...)[], fsep: string) => string;
        params: readonly ["...", "fsep"];
        pkg: Base;
    }

  • Readonlyhere: { fold: (parts: (...)[]) => string; params: readonly ["..."]; pkg: Here }

  • Readonlynchar: { fold: (s: string) => number; params: readonly ["x"]; pkg: Base }

    R counts characters, so we count code points rather than UTF-16 units

  • Readonlypaste: {
        defaults: { sep: " " };
        fold: (parts: (...)[], sep: string) => string;
        ignored: readonly ["collapse"];
        params: readonly ["...", "sep"];
        pkg: Base;
    }

  • Readonlypaste0: {
        defaults: { sep: "" };
        fold: (parts: (...)[], sep: string) => string;
        ignored: readonly ["collapse"];
        params: readonly ["...", "sep"];
        pkg: Base;
    }

  • Readonlytolower: { fold: (s: string) => string; params: readonly ["x"]; pkg: Base }

  • Readonlytoupper: { fold: (s: string) => string; params: readonly ["x"]; pkg: Base }

  • Readonlytrimws: { fold: (s: string) => string; params: readonly ["x"]; pkg: Base }

• Readonlyfold: <Info>(
      this: void,
      node: RNamedFunctionCall<Info>,
      resolveArg: (arg: RNode<Info>) => string | undefined,
  ) => string | number | undefined

  The string a call in the AST folds to; see foldStringCall.

• ReadonlypasteLike: ReadonlySet<string>

  the calls pasting their arguments together, see PasteLikeCalls
