This pr proposes the addition of colored brackets in order to help distinguish between scopes.
This is done by adding the entry:
brackettodefault_stylewhereby one can set the list of colouring functions to be used to color brackets.An internal function
color_bracketsis added such that brackets are colored consecutively by the scope level according to the color sequence passed in viabracket. The following brackets are considered:[[[](){}Note that the counterpart of
[[is two]characters instead of]]as this bracket would be parsed as an 'LBB' token (or as a 'SYMBOL_FUNCTION_CALL' and thus not passed on tocolor_brackets)Some more details are provided in the documentation.
