Regarding interface function names:<br>
<br>
I wonder what logic Luerl's names of do and eval follow:<br>
<br>
dofile/1, like eval/1, returns a pragmatic Ret <br>
<br>
while do/2 returns {String, State}<br>
<br>
Since you are exporting ps/1, there should maybe be a dochunk/2? <br>
<br>
And /1, too? <br>
<br>
Or should it maybe be evalchunk/1, dochunk/2 (the /2s with State as
second parameter)?<br>
<br>
Here are some relevant functions from Lua's C interface.<br>
<br>
<blockquote><b>luaL_dofile</b><br>
<br>
[-0, +?, m]<br>
int luaL_dofile (lua_State *L, const char *filename);<br>
Loads and runs the given file. It is defined as the following
macro:<br>
<br>
(luaL_loadfile(L, filename) || lua_pcall(L, 0, LUA_MULTRET,
0))<br>
It returns false if there are no errors or true in case of errors.<br>
<br>
<b>luaL_dostring</b><br>
<br>
[-0, +?, –]<br>
int luaL_dostring (lua_State *L, const char *str);<br>
Loads and runs the given string. It is defined as the following
macro:<br>
<br>
(luaL_loadstring(L, str) || lua_pcall(L, 0, LUA_MULTRET, 0))<br>
It returns false if there are no errors or true in case of errors.<br>
<br>
<b>luaL_loadstring</b><br>
<br>
[-0, +1, –]<br>
int luaL_loadstring (lua_State *L, const char *s);<br>
Loads a string as a Lua chunk. This function uses lua_load to load
the chunk in the zero-terminated string s.<br>
<br>
This function returns the same results as lua_load.<br>
<br>
Also as lua_load, this function only loads the chunk; it does not
run it.<br>
<br>
<b>luaL_newstate</b><br>
<br>
[-0, +0, –]<br>
lua_State *luaL_newstate (void);<br>
Creates a new Lua state. It calls lua_newstate with an allocator
based on the standard C realloc function and then sets a panic
function (see §4.6) that prints an error message to the standard
error output in case of fatal errors.<br>
<br>
Returns the new state, or NULL if there is a memory allocation
error.<br>
