From 8463dd24f815fe2b8f25fe9763e0a43023bfbb20 Mon Sep 17 00:00:00 2001 From: JSDurand Date: Fri, 23 Dec 2022 00:36:31 +0800 Subject: renaming core to chain and some other changes Some changes: - The core crate is renamed to "chain". - The crate "viz" is added, which will provide layered graph drawing algorithms. - A function is added to convert from a grammar to the regular language of its left-linear closures. - A function is added to convert from a nondeterministic finite automaton to its "null" closure. A null closure is the same automaton with edges added, as if some edges are "null". Whether an edge is null is determined by a function. Combined with the previous change, we can convert a grammar to the regular language of the null closure of its left-linear closures. --- Now it remains to test more grammars and add an Atom trait, before finishing the part about compilations. --- viz/src/lib.rs | 31 +++++++++++++++++++++++++++++++ 1 file changed, 31 insertions(+) create mode 100644 viz/src/lib.rs (limited to 'viz/src/lib.rs') diff --git a/viz/src/lib.rs b/viz/src/lib.rs new file mode 100644 index 0000000..b40c78a --- /dev/null +++ b/viz/src/lib.rs @@ -0,0 +1,31 @@ +//!
