From 9e09767e23a4edb6b31540195bfe885f83e080d7 Mon Sep 17 00:00:00 2001 From: bd Date: Tue, 28 Jan 2025 14:39:47 -0500 Subject: [Ongoing] Rewrite frontend to use Flex/Bison This is a merge of another experiment, so the changes are large: - separated "modules" directory into frontend/backend - adjusted module names and moved files for this to happen - removed modules lexer & parser - removed all the unit tests (most were outdated) - added Bison, flex, and C development tools to manifest.scm - added lexer.l, a source file used by the flex utility with a functioning lexing implementation - added parser.y, a source file used by the bison utility with a functioning parser implementation - added node.c and node.h, which parser.y uses to construct an AST of a C source file (up to binary ops) - added driver.c, a Guile-C interface that provides a module to scheme programs - added a Makefile to make all of this - added stuff to .gitignore --- src/unit-tests/parser/parser.test.scm | 30 ------------------------------ 1 file changed, 30 deletions(-) delete mode 100644 src/unit-tests/parser/parser.test.scm (limited to 'src/unit-tests/parser') diff --git a/src/unit-tests/parser/parser.test.scm b/src/unit-tests/parser/parser.test.scm deleted file mode 100644 index 32e1e6c..0000000 --- a/src/unit-tests/parser/parser.test.scm +++ /dev/null @@ -1,30 +0,0 @@ -;; -*- compile-command: "guile -L ./src/modules ./src/unit-tests/parser/parser.test.scm"; -*- -(use-modules (srfi srfi-64) - (parser parser)) - - -(test-begin "parser-harness") - - -(test-equal "trivial function main 2" - '(program (function (identifier "main") (return (constant 2)))) - (p-program '(int "main" left-paren void right-paren open-brace return 2 semi-colon close-brace))) - -(test-equal "trivial function foo 4" - '(program (function (identifier "foo") (return (constant 4)))) - (p-program '(int "foo" left-paren void right-paren open-brace return 4 semi-colon close-brace))) - -(test-error "trivial function bad double return" - (p-program '(int "foo" left-paren void right-paren open-brace return return 4 semi-colon close-brace))) - -(test-error "trivial function bad parens" - (p-program '(int "foo" right-paren void left-paren open-brace return 4 semi-colon close-brace))) - -(test-error "trivial function bad int parameter" - (p-program '(int "foo" left-paren int right-paren open-brace return 4 semi-colon close-brace))) - -(test-error "trivial function incomplete function" - (p-program '(int "foo" left-paren void right-paren open-brace return))) - - -(test-end "parser-harness") -- cgit v1.2.3
