Public Class methods

Public Instance methods

commentpop()

returns the content of the currently accumulated content cache

find_regex_token()

Find the next token that matches a regex. We look for these first.

find_token()

Find the next token, returning the string and the token.

fullscan()

scan the whole file basically just used for testing

munge_token(token, value)

Make any necessary changes to the token and/or value.

namepop()

Go up one in the namespace.

namespace()

Collect the current namespace.

namestack(value)
This value might have :in it, but we don‘t care — it‘ll be

handled normally when joining, and when popping we want to pop this full value, however long the namespace is.

scan_until(regex)

Provide some limited access to the scanner, for those tokens that need it.

skip()

Skip any skipchars in our remaining string.

slurpstring(terminators,escapes=%w{ \\ $ ' " n t s }+["\n"],ignore_invalid_escapes=false)

we‘ve encountered the start of a string… slurp in the rest of the string and return it

string=(string)

just parse a string, not a whole file
