The Lime language is used to define terminal and non-terminal symbols, their types and associated semantic actions.
Comments start with the hash symbol #, and extend up to the end of the line. There is no support for block comments.
All comments are discarded and behave as if they were replaced by a single space character.
# This is a comment
Snippets are arbitrary blocks of text used to embed code, types or other textual chunks in the Lime grammar. Snippets start with a sequence of consecutive opening brace { characters and end with the same number of consecutive closing brace characters }. Usually, snippets are braced by a single brace on either side, unless the snippet itself contains unpaired braces.
Leading and trailing whitespace is trimmed from snippets.
{} # An empty snippet
{[0-9]+} # A snippet containing a regular expression
{ [0-9]+ } # The same snippet as above
Strings are runs of text enclosed in single or double quotes. There is no support for escaping for now.
"This is a string."
'And so is this.'
Identifiers are used for symbols and optionally for their names. They can contain letters, numbers, underscores and dashes. Do not start identifiers with numbers or dashes.
