Crate ktrs_syntax 

Lossless Kotlin syntax tree. Node and token kinds mirror the Kotlin compiler’s PSI element types one-to-one (see kinds.tsv), so trees can be diffed against DebugUtil.psiToString.

Modules

tree

Tree: a parsed file as flat preorder arrays. An element (node or token) is its preorder index; navigation is index arithmetic, and token text is a slice of the source. Replaces rowan’s green/red trees, which allocate per node when built and per step when walked (see research/06-tree-library.md for the measurements).

Structs

Parse

A parsed file: the tree plus one message per ERROR_ELEMENT, in tree preorder.

TextRange

A range in text, represented as a pair of TextSize.

TextSize

A measure of text length. Also, equivalently, an index into text.

Enums

Functions

psi_dump

Renders parse exactly like IntelliJ’s DebugUtil.psiToString(file, true, false), the format of the compiler’s parser fixtures and of tools/psi-dump.
