lua/llex.c, branch v5.5.1 A mirror of https://github.com/lua/lua https://git.lua4.win/lua/atom?h=v5.5.1 2026-01-20T16:06:16+00:00 Some compilation options configurable from makefile 2026-01-20T16:06:16+00:00 Roberto Ierusalimschy roberto@inf.puc-rio.br 2026-01-20T16:06:16+00:00 urn:sha1:e992c6a95939c8e1fe357bfce481e0d0c762c3c6 Compilation options LUA_COMPAT_GLOBAL, LUA_COMPAT_LOOPVAR, and LUA_READLINELIB do not affect the API, so they can be changed through the make file. Slightly faster way to check for "global" 2025-05-16T17:51:07+00:00 Roberto Ierusalimschy roberto@inf.puc-rio.br 2025-05-16T17:51:07+00:00 urn:sha1:ded2ad2d86f44424c6b6e12bf1b75836cfa9e502 Internalized string "break" kept by the parser 2025-05-15T15:43:37+00:00 Roberto Ierusalimschy roberto@inf.puc-rio.br 2025-05-15T15:43:37+00:00 urn:sha1:3fb7a77731e6140674a6b13b73979256bfb95ce3 The parser uses "break" as fake label to compile "break" as "goto break". To avoid producing this string at each use, it keeps it available in its state. Remove compat code in parser when not needed 2025-05-13T14:50:43+00:00 Roberto Ierusalimschy roberto@inf.puc-rio.br 2025-05-13T14:50:43+00:00 urn:sha1:fded0b4a844990b1a6d0cda1aba25df33eb5f46f Using 'l_uint32' for unicode codepoints in scanner 2025-05-08T15:49:39+00:00 Roberto Ierusalimschy roberto@inf.puc-rio.br 2025-05-08T15:49:39+00:00 urn:sha1:d827e96f33056bcc0daca0c04b3273604f9d5986 'l_uint32' is enough for unicode codepoints (versus unsigned long), and the utf-8 library already uses that type. First implementation of global declarations 2025-05-05T19:24:59+00:00 Roberto Ierusalimschy roberto@inf.puc-rio.br 2025-05-05T19:24:59+00:00 urn:sha1:be8120906304a8658fab998587b969e0e42f5650 Growth factor of 1.5 for stack and lexical buffer 2025-03-31T16:44:41+00:00 Roberto Ierusalimschy roberto@inf.puc-rio.br 2025-03-31T16:44:41+00:00 urn:sha1:f4123b2fc2a662c08e3d7edc721241c251a22c4b Fixed conversion warnings from clang 2025-01-14T19:24:46+00:00 Roberto Ierusalimschy roberto@inf.puc-rio.br 2025-01-14T19:24:46+00:00 urn:sha1:3cdd49c94a8feed94853ba3a6adaa556fb34fd8d Plus some other details. (Option '-Wuninitialized' was removed from the makefile because it is already enabled by -Wall.) Scanner doesn't need to anchor reserved words 2024-12-30T19:53:51+00:00 Roberto Ierusalimschy roberto@inf.puc-rio.br 2024-12-30T19:53:51+00:00 urn:sha1:5894ca7b95d7fb05f1e93ee77e849a8d816d1c6d Scanner and parser use different tables for constants 2024-12-17T14:23:22+00:00 Roberto Ierusalimschy roberto@inf.puc-rio.br 2024-12-17T14:23:22+00:00 urn:sha1:1c40ff9faafed620aa0458b397bcbfbe19e0f663 Moreover, each function being parsed has its own table. The code is cleaner when each table is used for one specific purpose: The scanner uses its table to anchor and unify strings, mapping strings to themselves; the parser uses it to reuse constants in the code, mapping constants to their indices in the constant table. A different table for each task avoids false collisions.
