util
Evaluates files, strings, or input streams as Scala code, and returns the result.
Evaluates files, strings, or input streams as Scala code, and returns the result.
If target is None, the results are compiled to memory (and are therefore ephemeral). If
target is Some(path), the path must point to a directory, and classes will be saved into
that directory.
Eval also supports a limited set of preprocessors. Currently, "limited" means "exactly one":
directives of the form #include <file>.
The flow of evaluation is:
- extract a string of code from the file, string, or input stream
- run preprocessors on that string
- wrap processed code in an apply method in a generated class
- compile the class
- contruct an instance of that class
- return the result of apply()
