ull.git/src/modules/lexer, branch master A [WIP] C compiler built with GNU Guile, Flex, and Bison https://git.operationnull.com/ull.git/atom?h=master 2025-01-28T19:39:47+00:00 [Ongoing] Rewrite frontend to use Flex/Bison 2025-01-28T19:39:47+00:00 bd bdunahu@operationnull.com 2025-01-28T19:39:47+00:00 urn:sha1:9e09767e23a4edb6b31540195bfe885f83e080d7 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names and moved files for this to happen - removed modules lexer & parser - removed all the unit tests (most were outdated) - added Bison, flex, and C development tools to manifest.scm - added lexer.l, a source file used by the flex utility with a functioning lexing implementation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 Add lexer support for add, mul, div, and mod 2025-01-18T18:44:35+00:00 bd bdunahu@operationnull.com 2025-01-18T18:44:35+00:00 urn:sha1:78b84826c9251d88dc082fbcc625a63638066e06 set modules folder to modules path 2025-01-18T09:07:40+00:00 bd bdunahu@operationnull.com 2025-01-18T09:07:40+00:00 urn:sha1:14b2600bd58b0a4b09c6647c1d78ab7bccd4c1aa use a scheme procedures+eval to manage and transform AST 2025-01-18T08:25:47+00:00 bd bdunahu@operationnull.com 2025-01-18T08:25:47+00:00 urn:sha1:ddd448ae86e5730d5cd297f44ec89ee3fa3c0006 Removes records for a more-managable scheme-syntax approach. Modules+overriding allows for the IR itself to be represented and evaluated as scheme code during each transformation.
