Hole

The kinds of holes with associated matching behavior:

• Everything is the default hole that matches across newlines and within the bounds of code blocks or strings, and lazily between prefix and suffix strings in a given template.

• Expression matches expression-like syntax that corresponds to contiguous well-formed code structures or strings that are whitespace separated.

• Alphanum matches alphanumeric characters and underscore.

• Non_space matches one or more alphanumeric characters and punctuation like ., ;, and - that do not affect balanced syntax. Language dependent.

• Line matches zero or more characters up to a newline, including the newline.

• Blank matches one or more spaces or tabs.

• Regex matches a string based on a regular expression.
