Easy shorthand function to create a garbage expression at the given span
Breaks the input string into a vector of tokens. This tokenization only tries to classify separators like semicolons, pipes, etc from external bare values (values that haven't been classified further) Takes in a string and and offset, which is used to offset the spans created (for when this function is used to parse inner strings)
Try to parse a list of tokens into a block.
Parses a column path, adding in the preceding reference to $it if it's elided
Handle parsing math expressions, complete with working with the precedence of the operators
Converts a series of commands into a vec of spanned shapes ready for color-highlighting
