Module difft::parse::syntax

Syntax tree definitions with change metadata.

Structs

MatchedPos 🔒

SyntaxInfo 🔒

Fields that are common to both Syntax::List and Syntax::Atom.

Enums

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 {.

Functions

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 strings, 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.
