From df5294e88cc409d7adf3e10666bfcb40e34472b9 Mon Sep 17 00:00:00 2001 From: Dibyendu Majumdar Date: Sun, 1 Oct 2023 18:01:54 +0100 Subject: Chapter 3 - add vars and lexical scope. (#7) * Chapter 3 - add vars and lexical scope. * Fix typo * Overhaul graph viz Makes the scopes pointing into the graph being build more visually appealing. Constants are a printed with just the constant value. * Fix control edge color * Fix missing grouping operator parse Add a parens test. Shorten names 'Identifier' to 'Id' _lexer.match -> match require() passes a Node thru, so can be flow-coded. Uniform syntax error messages. Handy Lexer.toString for debugging. Drop Optional for null returns; less total code; less objects; less confusion. camelCase some fcns. * All parser helpers return Node, not void. Drop _ret. parseBlock and parseStatement now the same. * CLosely align chap2 and chap3 parsers Mostly whitespace aligned; dragged a few functions around to make more sense. I think the diff from Ch2 and Ch3 is down a few differences about what is a statement, plus all the symbol stuff for scopes and variables. * Add examples illustrating the symbol table creation. * Update docs and comments --------- Co-authored-by: Cliff Click --- chapter03/pom.xml | 14 ++++++++++++++ 1 file changed, 14 insertions(+) create mode 100644 chapter03/pom.xml (limited to 'chapter03/pom.xml') diff --git a/chapter03/pom.xml b/chapter03/pom.xml new file mode 100644 index 00000000..a484d5bd --- /dev/null +++ b/chapter03/pom.xml @@ -0,0 +1,14 @@ + + + 4.0.0 + + com.seaofnodes + simple + 1.0 + + chapter03 + jar + Chapter 3 + \ No newline at end of file -- cgit v1.2.3
