Normally styles backtrack to the lower level tokens when doing style resolution. For example if there is no custom styling for Name.Function, it will try to find the style of Name and use it. But this doesn't work with custom tokens:
import pygments
from pygments.lexer import RegexLexer
from pygments.token import *
from pygments.style import Style
from pygments.formatters.terminal256 import Terminal256Formatter
class TestLexer(RegexLexer):
tokens = {
'root': [
(r'A', Name.Function),
(r'B', Name.Function.CUSTOM),
]
}
class Style1(Style):
styles = {
Name: "#FA9BFA"
}
class Style2(Style):
styles = {
Name.Function: "#FA9BFA",
Name.Function.CUSTOM: "#FA9BFA"
}
for style in [Style1, Style2]:
print(pygments.highlight(
code="AB",
lexer=TestLexer(),
formatter=Terminal256Formatter(style=style),
).strip())I would expect both of these to work and output the same colors, but the initial style only highlights the Name.Function, and does not do anything for Name.Function.CUSTOM.
