smlExecScripts.exec

STRUCTURE

SYNOPSIS

Execute the script given in the file f.

DESCRIPTION

The script is executed only for its side effects. The execution standard out is redirected to src/AI/sml_inspection/buildheap/buildheap_yourscript where yourscript is the basename of f without extension. This file is worth expecting to debug uncaught errors.

FAILURE

Never fails.

EXAMPLE

- load "aiLib"; open aiLib;
- load "smlExecScripts"; open smlExecScripts;
(* output omitted *)
> val it = () : unit

val dir = HOLDIR ^ "/src/AI/sml_inspection"; (* user can choose *)
val scriptin = dir ^ "/script.sml";
val scriptout = dir ^ "/script-out";
(* output omitted *)

- writel scriptin
  ["load \"aiLib\"; open aiLib;",
   String.concatWith " " ["writel", mlquote scriptout, "[\"hello world!\"]"]];
> val it = (): unit

- exec_script scriptin;
> val it = (): unit

- readl "script-out";
> val it = ["hello world!"]: string list

COMMENTS

An Holmakefile might be placed in the same directory as the script to help exec_script (heapname,genscriptdep) figure out the dependencies of the script. For example, a Holmakefile might include the line INCLUDES = path-to-your-dependency.
