eg.
```lua
local err, file = os.open("LICENSE.md")
if err then
// do error handling stuff
end
// passing "a" to read() will read the whole file
print(file:read("a"))
```
also a minor GC bug in cosmoO_newError was fixed.
i'm going to try to phase out cosmoM_freezeGC & friends
since that would cause hell with this new
error handling solution. the only thing still using it is the GC.
currently, scripts seem to run fine. however I'm a bit worried about stack related issues. maybe i'll need to reset state->top as well? but not entirely sure
- currently only enabled on supported platforms (GNU C Compiler + Clang)
- when enabled, sped up examples/fibtest.cosmo by about 20% (avg of 11.179s prior and 8.799 after)
NOTE: malicious dumps can trivially cause crashes now by having junk function chunks
- now takes command line arguments:
Usage: ./bin/cosmo [-clsr] [args]
available options are:
-c <in> <out> compile <in> and dump to <out>
-l <in> load dump from <in>
-s <in...> compile and run <in...> script(s)
-r start the repl
- 'var' has some weird scoping connotations with users of JS. better to change it to 'let', which will decide whether to make the variable a local or a global
- 'func' looks visually appealing lol
- some minor refactoring done in cparse.c
This sets up room for the '__equal' metamethod to be added
- cosmoO_equals now requires the state to be passed
- cosmoV_equals now requires the state to be passed
- cosmoT_get now requires the state to be passed
