Module difft::parse::syntax

Expand description

Syntax tree definitions with change metadata.

Structs

AtomKind 🔒
MatchKind 🔒
A matched token (an atom, a delimiter, or a comment word).
StringKind 🔒
Different types of strings. We want to diff these the same way, but highlight them differently.
Syntax 🔒
TokenKind 🔒
Unlike atoms, tokens can be delimiters like {.

change_positions 🔒
Walk nodes and return a vec of all the changed positions.
change_positions_ 🔒
comment_positions 🔒
dbg_pos 🔒
filter_empty_ends 🔒
Skip line spans at the beginning or end that have zero width.
find_nodes_with_unique_content 🔒
Assumes that set_content_id has already run.
has_common_words 🔒
Are there sufficient common words that we should only highlight individual changed words?
init_all_info 🔒
Initialise all the fields in SyntaxInfo.
init_info 🔒
init_info_on_side 🔒
Set all the SyntaxInfo values for all the roots on a single side (LHS or RHS).
init_next_prev 🔒
print_as_dot 🔒
print_as_dot_ 🔒
set_content_id 🔒
set_content_is_unique 🔒
set_content_is_unique_from_counts 🔒
set_next_sibling 🔒
set_num_after 🔒
set_num_ancestors 🔒
set_parent 🔒
set_prev 🔒
For every syntax node in the tree, mark the previous node according to a preorder traversal.
set_prev_sibling 🔒
set_unique_id 🔒
split_atom_words 🔒
Given the text content from a comment or string, split it into MatchedPos values for the novel and unchanged words.
zip_pad_shorter 🔒
zip_repeat_shorter 🔒
Zip lhs with rhs, but repeat the last item from the shorter slice.
