e4f418f07c Local declaration in the REPL generates a warning 2024-09-27 10:00:35 -03:00

0acd55898d Added gcc option '-Wconversion' 
No warnings for standard numerical types. Still pending alternative
numerical types.

93fd6892f8 Fixed bug in 'multiline' 
'incomplete' was popping error message that should be used in case
there is no more lines to complete the input, that is, 'pushline'
returns NULL, due to end of file.

366c855648 lua.c loads 'readline' dynamically 
(See comments in luaconf.h.) This change allows easier compilation,
as Lua compiles and works even if the package 'readline' is absent
from the system. Moreover, non-interactive uses don't load the library,
making the stand-alone slightly faster for small loads.

a08d82eb13 llimits.h being used by all Lua code 
The definitions in llimits.h are useful not only for the core. That
header only defines types and '#define's, so libs and core still do
not share any real code/data.

165389b27b New interface to function 'luaL_openselectedlibs' 
Instead of preloading all non-loaded libraries, there is another
mask to select which libraries to preload.

e81f586001 Removed compatibility option LUA_COMPAT_GCPARAMS 
The meaning of different GC parameters changed, so there is point in
supporting old values for them. The new code simply ignores the
parameters when changing the GC mode, so the incompatibility is small.

e2cc179454 New option "setparms" for 'collectgarbage' 
The generational mode also uses the parameters for the incremental
mode in its major collections, so it should be easy to change those
parameters without having to change the GC mode.

09f3c2372f Option '-l' discards version sufix from file name 
Like 'require', the command-line option '-l' discards an optional
version suffix (everything after an hyphen) from a file name when
creating the module name.

65434b4d1b Option '-l' can give a name for the global variable.

131e3fd814 Avoid using 'signal' when 'sigaction' is available 
The semantics of 'signal' varies a lot among different implementations;
'sigaction' ensures a more consistent behavior.

69b71a6919 _PROMPT can have non-string values 
'get_prompt' uses 'luaL_tolstring' to convert _PROMPT or _PROMPT2
value to a string. That conversion may invoke a '__tostring'
metamethod.

be78aeae4c Default for warnings changed to "off" 
Warnings are mostly a tool to help developers (e.g., by showing hidden
error messages); regular users usually don't need to see them.

a1d8eb2743 Added control messages to warnings 
Added the concept of control messages to the warning system, plus the
implementation of the controls "@on"/"@off" to turn warnings on/off.
Moreover, the warning system in the test library adds some other
controls to ease the test of warnings.

faaf7e481f Removed use of 'rl_inhibit_completion' in 'lua.c' 
Some old systems (e.g., Mac OS X 10.4) do not define
'rl_inhibit_completion', even when line history is available.
Anyway, the user can configure this option externally, using '~/.inputrc'.

an extra ";" at the end is enough to stop Lua printing the result
("return exp;;" is not valid)
