14INTRODUCTION
15
16The goal of Yueliang is to implement Lua 5 in Lua 5. Such a codebase, if
17well documented, can be a useful prototyping and educational tool.
18Initially, the focus is on the front side of Lua, i.e. the lexical
19analyzer, the parser and the code generator, in order to generate binary
20chunks. Yueliang currently produces the exact binary chunk as the
21original Lua 5 itself for Lua 5.0.3 and Lua 5.1.3. Yueliang is moon in
22Mandarin.
23
24A port of the back side (the VM) is being considered, but note that
25there is a recent project on LuaForge called LuLu that does just this.
26
27Note: the codebase is currently a no-brainer port of Lua's front side C
28source code to Lua code, and the C heritage is retained as much as
29possible to allow for easy comparison. Due to certain implementation
30methods, processing might be slow (especially if the source file causes
31a lot of string processing.) The initial version is not meant to be
32fast. Even unused arguments are retained. Asserts are currently enabled.
33While the Lua code itself is portable, portions of the code is
34hard-coded to generate output for an x86-type platform (32-bit ints,
35doubles, little-endian.)
36
37See the test_lua directory for an automatic tester, test_scripts*.lua.
38Only the lexer currently has a basic test suite. Performance for the
39no-brainer port of the Lua 5.0.2 front end in Yueliang 0.1.0 is 28
40seconds on an Athlon 2500+, or about 29.5KB/sec. (Native C is virtually
41instantaneous, so a comparison is pointless, really.) I think a test
42suite for the parser will be better than running it on random files. See
43below for a list of todos.
44
45For versions of Yueliang corresponding to older minor releases of Lua,
46for example Lua 5.0.2 or Lua 5.1.1, please look at the README files in
47each of the orig-5.* directory for information on the last version of
48Yueliang corresponding to the particular Lua release.

52NOTES
53
54* there is a failed assert in luaK:addk for both versions of lcode.lua,
55 the assert is currently incorrectly written
56* luaG_checkcode() in both versions of lparser.lua has currently not
57 been implemented (better put in the runtime backend?)
58* need to check compliance of lexers with recognizing characters beyond
59 normal ASCII (accented characters) when used in identifiers

63WHAT'S NEW
64
65Major changes for version 0.4.1 (details in the ChangeLog):
66* Tested native 5.0.x and 5.1.x parsers with lots of test cases
67* Fixed two bugs in native 5.1.x parser, # and % operator handling
68
69Major changes for version 0.4.0 (details in the ChangeLog):
70* A working native parser skeleton for Lua 5.1.x, plus code
71 to deal with variable classification
72* Sample parser log files covering all of the grammar
73
74Major changes for version 0.3.2 (details in the ChangeLog):
75* A working native lexer for Lua 5.1.x
76
77Major changes for version 0.3.1 (details in the ChangeLog):
78* Mark 2 of the native parser skeleton for 5.0.3 which does
79 variable classification into locals, upvalues or globals
80* Sample parser log files exercising variable classification
81
82Major changes for version 0.3.0 (details in the ChangeLog):
83* Native parser skeleton for 5.0.3 mostly works
84* Sample parser log files covering all of the grammar

90SOME SIZE STATS
91
92Here are some 0.1.0 size statistics (note that embedding the sources is
93redundant or pretty useless, as you will need an already present front
94end to process the source code!) for the 6 files main in orig-5.0.3
95minus luac.lua:
96
97 Size Zipped
98Original sources* 130162 29546
99with LuaSrcDiet* 48308 13841
100luac 108174 32238
101luac -s 64930 21867
102
103*note: embedding these would be a little pointless
104
105There are some more size stats in the README file in the nat-5.0.3
106directory, for native lexers.

110IMPLEMENTATION PLAN
111
112Here are some ideas, in no particular order or priority, with no
113particular implementation time frame:
114
115(a) A straight no-brainer port of Lua's front side C source code to
116 Lua code, no optimization or heavy rewriting is done (MOSTLY DONE)
117(b) A test suite for the lexer (MOSTLY DONE)
118(c) A test suite for the:
119 (i) parser (MOSTLY DONE)
120 (ii) code generator (CAN ADAPT LUA'S TEST SUITE)
121(d) Documentation for Lua code generation (STUDYING)
122(e) A straight no-brainer port of Lua's back side C source code to
123 Lua code, no optimization or heavy rewriting is done (ON HIATUS)
124 *** NOTE: there is a Lua-on-Lua project called LuLu on LuaForge
125(f) A test suite for the VM (CAN ADAPT LUA'S TEST SUITE)
126(g) Partial rewrites of Yueliang. (NATIVE LEXERS AND PARSERS DONE
127 FOR BOTH 5.0 AND 5.1)
128(h) Addition of features to Yueliang.

3This directory contains versions of front end files that are rewritten
4to be more "native" to Lua. These files should be considered as
5exercises in exploring ways to write the front end, for example, to
6write a front end that is optimized for size, etc. See also file size
7data further below.
8
9The following are the different versions available (mk2 == "mark 2",
10this is commonly used in the UK, e.g. for aeroplanes during WWII):
11
12Lexers
13------
14
15WARNING: Theses lexer may or may not exhibit exact behaviour when lexing
16strings or long strings with embedded CRLF newlines. The CRLF sequence
17may be translated into LF (the reference manual is unclear on this.) The
18user is advised to stick to LF line endings exclusively.
19
20llex_mk2 Rewritten from original ported code to become more
21 Lua-like. Still uses a stream-based input interface.
22 MK2 still scans using a per-character function that
23 is pretty inefficient.
24
25 Status: TESTED
26
27llex_mk3 A rewritten version of MK2 that needs input to be
28 entered as a single string. Unless an application's
29 need is very unusual, this should not be a problem.
30 It will not work for per-line interaction, though.
31 MK3 no longer needs stream input functions. This
32 version is also heavily optimized for size. MK3 scans
33 using find functions and doesn't create many strings.
34
35 Status: TESTED
36
37llex_mk4 A rewritten version of MK3 that is line-oriented.
38 This allows a command-line version that works in the
39 usual way to be written.
40
41 Status: TESTED

66
67(1) mk3 does not have a file input streaming function
68
69(2) Speed was benchmarked using a Sempron 3000+. Benchmark scripts are
70in the test directories. Best of first three figures quoted. This is a
71measurement of raw lexer speed, i.e. tokens are read but no processing
72is done. All files are read in entirely before running the lexer.
73
74The performance of the orig-5.0.3 parser is probably a whole magnitude
75less than the orig-5.0.3 lexer performance.
76
77Parsers
78-------
79
80lparser_mk3 Written for the simplified lexer interface of llex_mk3+.
81 (Should be compatible with llex_mk4 too, but untested.)
82 This is a lexer skeleton, stripped of codegen code. See
83 the comments in the source code for more information.
84 Without logging messages and comments, it's under 600 LOC.
85
86 Sample output of the parser message logger can be found
87 in the test/parser_log subdirectory.
88
89 Tested with test_parser-5.0.lua, the Lua 5.0.x parser test
90 cases in the test_lua/ directory, appears to be fine.
91
92 Status: SNIPPETS APPEAR TO WORK
93
94lparser_mk3b As above, with variable management code added. In order
95 to use the parser usefully, variable management code is
96 a big step forward, allowing the parser to differentiate
97 locals, upvalues and globals. The number of added lines
98 is around 100 LOC. A binary chunk of lparser_mk3b
99 (stripped) is 18076 bytes.
100
101 Sample output of the parser message logger can be found
102 in the test/parser_log subdirectory.
103
104 Tested with test_parser-5.0.lua, the Lua 5.0.x parser test
105 cases in the test_lua/ directory, appears to be fine.
106
107 Status: SNIPPETS APPEAR TO WORK
108
109There will be no further development beyond lparser_mk3b. Further work
110will focus on a 5.1.x equivalent, for which both a parser skeleton and a
111parser with full code generation using nicely commented code is planned.
112
113Other notes:
114------------
115
116For Lua 5.0.2, see Yueliang 0.1.3, which was the last release of Lua
1175.0.2 material.
118
119Test scripts for the lexer should probably be consolidated, but it's a
120little difficult because not all lexers give the same error messages or
121use the same token names or format.

16-- Notes:
17-- * this is a Lua 5.0.x parser skeleton, for llex_mk3.lua lexer
18-- * written as a module factory with recognizable lparser.c roots
19-- * builds some data, performs logging for educational purposes
20-- * target is to have relatively efficient and clear code
21-- * needs one parameter, a lexer module that implements:
22-- luaX:lex() - returns appropriate [token, semantic info] pairs
23-- luaX.ln - current line number
24-- luaX:errorline(s, [line]) - dies with error message
25--
26-- Usage example:
27-- lex_init = require("llex_mk3.lua")
28-- parser_init = require("lparser_mk3.lua")
29-- local luaX = lex_init(chunk, "=string")
30-- local luaY = parser_init(luaX)
31-- local fs = luaY:parser()
32--
33-- Development notes:
34-- * see test_parser-5.0.lua for grammar elements based on lparser.c
35-- * lparser has a few extra items to help parsing/syntax checking
36-- (a) line number (error reporting), lookahead token storage
37-- (b) per-prototype states needs a storage list
38-- (c) 'break' needs a per-block flag in a stack
39-- (d) 'kind' (v.k) testing needed in expr_stat() and assignment()
40-- for disambiguation, thus v.k manipulation is retained
41-- (e) one line # var (lastln) for ambiguous (split line) function
42-- call checking
43-- (f) most line number function call args retained for future use
44-- (g) Lua 4 compatibility code completely removed
45-- (h) no variable management code! singlevar() always returns VLOCAL
46-- * parsing starts from the end of this file in luaY:parser()

16-- Notes:
17-- * this is a Lua 5.0.x parser skeleton, for llex_mk3.lua lexer
18-- * written as a module factory with recognizable lparser.c roots
19-- * builds some data, performs logging for educational purposes
20-- * target is to have relatively efficient and clear code
21-- * needs one parameter, a lexer module that implements:
22-- luaX:lex() - returns appropriate [token, semantic info] pairs
23-- luaX.ln - current line number
24-- luaX:errorline(s, [line]) - dies with error message
25--
26-- Usage example:
27-- lex_init = require("llex_mk3.lua")
28-- parser_init = require("lparser_mk3.lua")
29-- local luaX = lex_init(chunk, "=string")
30-- local luaY = parser_init(luaX)
31-- local fs = luaY:parser()
32--
33-- Development notes:
34-- * see test_parser-5.0.lua for grammar elements based on lparser.c
35-- * lparser has a few extra items to help parsing/syntax checking
36-- (a) line number (error reporting), lookahead token storage
37-- (b) per-prototype states needs a storage list
38-- (c) 'break' needs a per-block flag in a stack
39-- (d) 'kind' (v.k) testing needed in expr_stat() and assignment()
40-- for disambiguation, thus v.k manipulation is retained
41-- (e) one line # var (lastln) for ambiguous (split line) function
42-- call checking
43-- (f) most line number function call args retained for future use
44-- (g) Lua 4 compatibility code completely removed
45-- (h) minimal variable management code to differentiate each type
46-- * parsing starts from the end of this file in luaY:parser()

3This directory contains versions of front end files that are rewritten
4to be more "native" to Lua. These files should be considered as
5exercises in exploring ways to write the front end, for example, to
6write a front end that is optimized for size, etc. See also file size
7data further below.
8
9The following are the different versions available (mk2 == "mark 2",
10this is commonly used in the UK, e.g. for aeroplanes during WWII):
11
12Lexers
13------
14
15NOTE: These lexers should behave mostly identically to the original C
16lexer. Locale support for non-standard decimal points is missing. Also,
17all strings and long strings have line endings normalized to LF.
18
19llex_mk2 Rewritten from original ported code to become more
20 Lua-like. Needs input to be entered as a single string.
21 Unless an application's need is very unusual, this
22 should not be a problem. It will not work for per-line
23 interaction, though. This version is also somewhat
24 optimized for size; its stripped binary chunk size is
25 3716 bytes.
26
27 Status: TESTED
28
29Parsers
30-------
31
32lparser_mk2 Written for the simplified lexer interface of llex_mk2.
33 This is a lexer skeleton, stripped of codegen code. Has
34 a minimum of variable management code added, and tracks
35 the is_vararg flag of a function. See the comments in
36 the source code for more information. Without logging
37 messages and comments, it should be under 600 LOC. A
38 binary chunk of lparser_mk2 (stripped) is 15783 bytes.
39
40 Sample output of the parser message logger can be found
41 in the test/parser_log subdirectory.
42
43 Tested with test_parser-5.1.lua, the Lua 5.1.x parser test
44 cases in the test_lua/ directory, appears to be fine.
45
46 Compared to the 5.0.x parser skeleton, the main changes
47 are: (a) 'arg' not implemented, so it appears as a global,
48 and (b) '...' recognized as the last function parameter.
49
50 Status: SNIPPETS APPEAR TO WORK

16-- Notes:
17-- * takes in the entire source at once
18-- * greatly simplified chunkid, error handling
19-- * NO shbang handling (it's done elsewhere in Lua 5.1)
20-- * NO localized decimal point replacement magic
21-- * NO limit to number of lines (MAX_INT = 2147483645)
22-- * NO support for compatible long strings (LUA_COMPAT_LSTR)
23-- * NO next(), lookahead() because I want next() to set tok and
24-- seminfo that are locals, and that can only be done easily in
25-- lparser, not llex. lastline would be handled in lparser too.

16-- Notes:
17-- * this is a Lua 5.1.x parser skeleton, for the llex_mk2.lua lexer
18-- * builds some data, performs logging for educational purposes
19-- * target is to have relatively efficient and clear code
20-- * NO parsing limitations, since it is only a parser skeleton. Some
21-- limits set in the default sources (in luaconf.h) are:
22-- LUAI_MAXVARS = 200
23-- LUAI_MAXUPVALUES = 60
24-- LUAI_MAXCCALLS = 200
25-- * NO support for 'arg' vararg functions (LUA_COMPAT_VARARG)
26-- * init(llex) needs one parameter, a lexer module that implements:
27-- llex.lex() - returns appropriate [token, semantic info] pairs
28-- llex.ln - current line number
29-- llex.errorline(s, [line]) - dies with error message
30--
31-- Usage example:
32-- local llex = require("llex_mk2")
33-- local lparser = require("lparser_mk2")
34-- llex.init(source_code, source_code_name)
35-- lparser.init(llex)
36-- local fs = lparser.parser()
37--
38-- Development notes:
39-- * see test_parser-5.1.lua for grammar elements based on lparser.c
40-- * next() (renamed to nextt) and lookahead() has been moved from llex;
41-- it's more convenient to keep tok, seminfo as local variables here
42-- * syntaxerror() is from llex, easier to keep here since little token
43-- translation needed in preparation of error message
44-- * lparser has a few extra items to help parsing/syntax checking
45-- (a) line number (error reporting), lookahead token storage
46-- * (b) per-prototype states needs a storage list
47-- * (c) 'break' needs a per-block flag in a stack
48-- * (d) 'kind' (v.k) testing needed in expr_stat() and assignment()
49-- for disambiguation, thus v.k manipulation is retained
50-- * (e) one line # var (lastln) for ambiguous (split line) function
51-- call checking
52-- * (f) LUA_COMPAT_VARARG compatibility code completely removed
53-- * (g) minimal variable management code to differentiate each type
54-- * parsing starts from the end of this file in parser()

1orig-5.0.3
2
3This is a straightforward port of the Lua 5.0.3 front end (lexical
4analyzer, parser, code generator, binary chunk dumper.)
5
6The front end files are:
7
8 lopcodes.lua opcode definition
9 lzio.lua input streams
10 llex.lua lexical analyzer
11 lparser.lua parser
12 lcode.lua code generator
13 ldump.lua binary chunk dumper
14
15Status: operational, passes all current tests (non-exhaustive)
16
17Major test scripts are:
18
19 test/test_llex.lua exercises test cases
20 test/test_lparser2.lua exercises test cases
21
22luac.lua is a clone of Lua 5.0.3's luac.lua, except that it generates a
23binary chunk using Yueliang's front end implementation.
24
25Note that performance is not a consideration. The code tries to stay
26faithful to its C roots, so that if you were to do anything using this
27codebase, backporting the changes to C will be easy. As such, this
28codebase is meant for learning or prototyping purposes.
29
30Many parameters are unused, because call arguments are retained as far
31as possible. Changes and deletions are described wherever possible, but
32documentation of changes is not comprehensive.
33
34These files will stay faithful to the equivalent C files or modules in
35Lua 5.0.3. For rewrites or new features, a new directory will be created
36and a different set of files maintained. For Lua 5.1, a new directory
37will be created.
38
39The test directory has several primitive test scripts. Much better
40testing is planned. Eventually, the codebase will be validated using
41automated tests, so that any changes that breaks the system can be
42caught easily.
43
44The tools directory has a call graph generator, showing what gets
45called. Specific modules and functions can be monitored, and some
46parameters and return values are shown. This is a demonstration of the
47flexibility and ease of manipulation of using a relatively inefficient
48global table scheme.
49

16-- Notes:
17-- * one function manipulate a pointer argument with a simple data type
18-- (can't be emulated by a table, ambiguous), now returns that value:
19-- luaK:concat(fs, l1, l2)
20-- * some function parameters changed to boolean, additional code
21-- translates boolean back to 1/0 for instruction fields
22-- * Added:
23-- luaK:ttisnumber(o) (from lobject.h)
24-- luaK:nvalue(o) (from lobject.h)
25-- luaK:setnilvalue(o) (from lobject.h)

17-- * intended to 'imitate' llex.c code; performance is not a concern
18-- * tokens are strings; code structure largely retained
19-- * deleted stuff (compared to llex.c) are noted, comments retained
20-- * Added:
21-- luaX:chunkid (from lobject.c)
22-- * To use the lexer:
23-- (1) luaX:init() to initialize the lexer
24-- (2) luaX:setinput() to set the input stream to lex, get LS
25-- (3) call luaX:lex() to get tokens, until "TK_EOS":
26-- LS.t.token = luaX:lex(LS, LS.t)
27-- * since EOZ is returned as a string, be careful when regexp testing

30 We assume that instructions are unsigned numbers.
31 All instructions have an opcode in the first 6 bits.
32 Instructions can have the following fields:
33 'A' : 8 bits
34 'B' : 9 bits
35 'C' : 9 bits
36 'Bx' : 18 bits ('B' and 'C' together)
37 'sBx' : signed Bx
38
39 A signed argument is represented in excess K; that is, the number
40 value is the unsigned value minus K. K is exactly the maximum value
41 for that argument (so that -max is represented by 0, and +max is
42 represented by 2*max), which is half the maximum for the corresponding
43 unsigned argument.

254 Notes:
255 (1) In OP_CALL, if (B == 0) then B = top. C is the number of returns - 1,
256 and can be 0: OP_CALL then sets 'top' to last_result+1, so
257 next open instruction (OP_CALL, OP_RETURN, OP_SETLIST) may use 'top'.
258
259 (2) In OP_RETURN, if (B == 0) then return up to 'top'
260
261 (3) For comparisons, B specifies what conditions the test should accept.
262
263 (4) All 'skips' (pc++) assume that next instruction is a jump
264
265 (5) OP_SETLISTO is used when the last item in a table constructor is a
266 function, so the number of elements set is up to top of stack

3This is a straightforward port of the Lua 5.1.3 front end (lexical
4analyzer, parser, code generator, binary chunk dumper.)
5
6The front end files are:
7
8 lopcodes.lua opcode definition
9 lzio.lua input streams
10 llex.lua lexical analyzer
11 lparser.lua parser
12 lcode.lua code generator
13 ldump.lua binary chunk dumper
14
15Status: operational, passes all current tests (non-exhaustive)
16
17Major test scripts are:
18
19 test/test_llex.lua exercises test cases
20 test/test_lparser2.lua exercises test cases
21
22luac.lua is a clone of Lua 5.1.3's luac.lua, except that it generates a
23binary chunk using Yueliang's front end implementation.
24
25See the README file in orig-5.0.3 for a discussion.
26
27The following is some performance data. Note that absolutely nothing has
28been done to optimize the code; it is meant to mirror the original C as
29an educational tool.

45(1) Speed was benchmarked using a Sempron 3000+. Benchmark scripts are
46in the test directories. Best of first three figures quoted. This is a
47measurement of raw lexer speed, i.e. tokens are read but no processing
48is done. All files are read in entirely before running the lexer.

16-- Notes:
17-- * WARNING! byte order (little endian) and data type sizes for header
18-- signature values hard-coded; see luaU:header
19-- * chunk writer generators are included, see below
20-- * one significant difference is that instructions are still in table
21-- form (with OP/A/B/C/Bx fields) and luaP:Instruction() is needed to
22-- convert them into 4-char strings
23--
24-- Not implemented:
25-- * DumpVar, DumpMem has been removed
26-- * DumpVector folded into folded into DumpDebug, DumpCode
27--
28-- Added:
29-- * for convenience, the following two functions have been added:
30-- luaU:make_setS: create a chunk writer that writes to a string
31-- luaU:make_setF: create a chunk writer that writes to a file
32-- (lua.h contains a typedef for lua_Writer/lua_Chunkwriter, and
33-- a Lua-based implementation exists, writer() in lstrlib.c)
34-- * luaU:ttype(o) (from lobject.h)
35-- * for converting number types to its binary equivalent:
36-- luaU:from_double(x): encode double value for writing
37-- luaU:from_int(x): encode integer value for writing
38-- (error checking is limited for these conversion functions)
39-- (double conversion does not support denormals or NaNs)
40--
41-- Changed in 5.1.x:
42-- * the dumper was mostly rewritten in Lua 5.1.x, so notes on the
43-- differences between 5.0.x and 5.1.x is limited
44-- * LUAC_VERSION bumped to 0x51, LUAC_FORMAT added
45-- * developer is expected to adjust LUAC_FORMAT in order to identify
46-- non-standard binary chunk formats
47-- * header signature code is smaller, has been simplified, and is
48-- tested as a single unit; its logic is shared with the undumper
49-- * no more endian conversion, invalid endianness mean rejection
50-- * opcode field sizes are no longer exposed in the header
51-- * code moved to front of a prototype, followed by constants
52-- * debug information moved to the end of the binary chunk, and the
53-- relevant functions folded into a single function
54-- * luaU:dump returns a writer status code
55-- * chunk writer now implements status code because dumper uses it
56-- * luaU:endianness removed

16-- Notes:
17-- * intended to 'imitate' llex.c code; performance is not a concern
18-- * tokens are strings; code structure largely retained
19-- * deleted stuff (compared to llex.c) are noted, comments retained
20-- * nextc() returns the currently read character to simplify coding
21-- here; next() in llex.c does not return anything
22-- * compatibility code is marked with "--#" comments
23--
24-- Added:
25-- * luaX:chunkid (function luaO_chunkid from lobject.c)
26-- * luaX:str2d (function luaO_str2d from lobject.c)
27-- * luaX.LUA_QS used in luaX:lexerror (from luaconf.h)
28-- * luaX.LUA_COMPAT_LSTR in luaX:read_long_string (from luaconf.h)
29-- * luaX.MAX_INT used in luaX:inclinenumber (from llimits.h)
30--
31-- To use the lexer:
32-- (1) luaX:init() to initialize the lexer
33-- (2) luaX:setinput() to set the input stream to lex
34-- (3) call luaX:next() or luaX:luaX:lookahead() to get tokens,
35-- until "TK_EOS": luaX:next()
36-- * since EOZ is returned as a string, be careful when regexp testing
37--
38-- Not implemented:
39-- * luaX_newstring: not required by this Lua implementation
40-- * buffer MAX_SIZET size limit (from llimits.h) test not implemented
41-- in the interest of performance
42-- * locale-aware number handling is largely redundant as Lua's
43-- tonumber() function is already capable of this
44--
45-- Changed in 5.1.x:
46-- * TK_NAME token order moved down
47-- * string representation for TK_NAME, TK_NUMBER, TK_STRING changed
48-- * token struct renamed to lower case (LS -> ls)
49-- * LexState struct: removed nestlevel, added decpoint
50-- * error message functions have been greatly simplified
51-- * token2string renamed to luaX_tokens, exposed in llex.h
52-- * lexer now handles all kinds of newlines, including CRLF
53-- * shbang first line handling removed from luaX:setinput;
54-- it is now done in lauxlib.c (luaL_loadfile)
55-- * next(ls) macro renamed to nextc(ls) due to new luaX_next function
56-- * EXTRABUFF and MAXNOCHECK removed due to lexer changes
57-- * checkbuffer(ls, len) macro deleted
58-- * luaX:read_numeral now has 3 support functions: luaX:trydecpoint,
59-- luaX:buffreplace and (luaO_str2d from lobject.c) luaX:str2d
60-- * luaX:read_numeral is now more promiscuous in slurping characters;
61-- hexadecimal numbers was added, locale-aware decimal points too
62-- * luaX:skip_sep is new; used by luaX:read_long_string
63-- * luaX:read_long_string handles new-style long blocks, with some
64-- optional compatibility code
65-- * luaX:llex: parts changed to support new-style long blocks
66-- * luaX:llex: readname functionality has been folded in

30--
31-- Changed in 5.1.x:
32-- * POS_OP added, instruction field positions changed
33-- * some symbol names may have changed, e.g. LUAI_BITSINT
34-- * new operators for RK indices: BITRK, ISK(x), INDEXK(r), RKASK(x)

48 We assume that instructions are unsigned numbers.
49 All instructions have an opcode in the first 6 bits.
50 Instructions can have the following fields:
51 'A' : 8 bits
52 'B' : 9 bits
53 'C' : 9 bits
54 'Bx' : 18 bits ('B' and 'C' together)
55 'sBx' : signed Bx
56
57 A signed argument is represented in excess K; that is, the number
58 value is the unsigned value minus K. K is exactly the maximum value
59 for that argument (so that -max is represented by 0, and +max is
60 represented by 2*max), which is half the maximum for the corresponding
61 unsigned argument.

315 Notes:
316 (*) In OP_CALL, if (B == 0) then B = top. C is the number of returns - 1,
317 and can be 0: OP_CALL then sets 'top' to last_result+1, so
318 next open instruction (OP_CALL, OP_RETURN, OP_SETLIST) may use 'top'.
319 (*) In OP_VARARG, if (B == 0) then use actual number of varargs and
320 set top (like in OP_CALL with C == 0).
321 (*) In OP_RETURN, if (B == 0) then return up to 'top'
322 (*) In OP_SETLIST, if (B == 0) then B = 'top';
323 if (C == 0) then next 'instruction' is real C
324 (*) For comparisons, A specifies what condition the test should accept
325 (true or false).

16-- Notes:
17-- * EOZ is implemented as a string, "EOZ"
18-- * Format of z structure (ZIO)
19-- z.n -- bytes still unread
20-- z.p -- last read position position in buffer
21-- z.reader -- chunk reader function
22-- z.data -- additional data
23-- * Current position, p, is now last read index instead of a pointer
24--
25-- Not implemented:
26-- * luaZ_lookahead: used only in lapi.c:lua_load to detect binary chunk
27-- * luaZ_read: used only in lundump.c:ezread to read +1 bytes
28-- * luaZ_openspace: dropped; let Lua handle buffers as strings (used in
29-- lundump.c:LoadString & lvm.c:luaV_concat)
30-- * luaZ buffer macros: dropped; buffers are handled as strings
31-- * lauxlib.c:getF reader implementation has an extraline flag to
32-- skip over a shbang (#!) line, this is not implemented here
33--
34-- Added:
35-- (both of the following are vaguely adapted from lauxlib.c)
36-- * luaZ:make_getS: create Reader from a string
37-- * luaZ:make_getF: create Reader that reads from a file
38--
39-- Changed in 5.1.x:
40-- * Chunkreader renamed to Reader (ditto with Chunkwriter)
41-- * Zio struct: no more name string, added Lua state for reader

11For example, to run the 5.0.x script tester:
12
13 >lua test_scripts-5.0.lua
14
15Or, if you have both Lua 5.0.x and Lua 5.1.x, you can prepare two
16binaries and run them like this:
17
18 >lua5.0 test_scripts-5.0.lua
19 >lua5.1 test_scripts-5.1.lua
20
21If the compilation result is exact, "CORRECT" is printed, otherwise both
22binary chunks are written to the current directory as bc1.out and
23bc2.out. You can use a disassembly tool like ChunkSpy to generate
24listings for both files, then they can be compared with a visual diff
25tool. ChunkSpy 0.9.8 supports 5.0.x and 5.1.x.
26
27For testing additional files, add the argument "ALL" like this:
28
29 >lua test_scripts-5.0.lua ALL
30
31This will pull in additional personal script files for testing. But in
32order to do so, you'd have to adjust the files files-other-*.txt.

45-------------------
46
47The script files test_parser-5.0.lua and test_parser-5.1.lua contains
48many test cases for both parsers. There are a lot of failure cases as
49well as pass cases in order to exercise the parsers well, though the
50test list is not exhaustive.
51
52 test_parser-5.0.lua 503 test cases
53 test_parser-5.1.lua 524 test cases
54
55For the actual test scripts, see test_lparser2.lua in the respective
56test directories of each front end. The 5.0.x front end of Yueliang
57passed all the tests in test_parser-5.0.lua without any failures, while
58testing of the 5.1.x front end using test_parser-5.1.lua led to one
59bug found and fixed.
60
61For Lua 5.0.2, see Yueliang 0.1.3, which was the last release of Lua
625.0.2 material.
63
64For Lua 5.1.1, see Yueliang 0.2.1, which was the last release of Lua
655.1.1 material.
