Lua 5.2+ uses loadfile(filename, mode, env), not loadfile(filename,
env). While this is a minor incompatibility, it'd be nice to be
consistent as much as possible.
We try to handle the incorrect case too, as obviously we don't want to
break existing programs.
This moves expect from the bios into a new craftos.expect module,
removing the internal _G["~expect"] definition. Apparently people were
using this irrespective of the "don't use this" comment, so we need to
find another solution.
While this does introduce some ugliness (having to load the module in
weird ways for programs, duplicating the expect function in memory), it
does allow people to use the function in a supported way, and removes
the global ugliness.
I'm not entirely sure how useful all of these will be yet - still
trying to work out what/when to test things, but hopefully this'll
be a useful datapoint.
Equivalent to `pastebin run`, but allows running arbitrary URLs
instead.
Is this a little questionable? Yes - people shouldn't be downloading
and running code from the internet. But hey, people do that already,
so we might as well make it convenient.
- Make mcfly's stubbing system a little more fault-tolerant.
- Add a small utility function which redirects print, printError and
write to capture their output, rather than printing to the terminal.
This can then be matched against in order to determine a program's
output.
It's a little flakey - you can't use it multiple times in an it
block, etc... but it's a nice feature.
- Add a small couple of tests to delete as a proof-of-concept.
- Define an expect(index, actual_value, types...) helper function which
takes an argument index, value and list of permissable types and
ensures the value is of one of those types.
If not, it will produce an error message with the expected and actual
type, as well as the argument number and (if available) the function
name.
- Expose expect in the global scope as _G["~expect"], hopefully making
it clear it is internal.
- Replace most manual type checks with this helper method.
- Write tests to ensure this argument validation works as expected
Also fix a couple of bugs exposed by this refactor and the subsequent
tests:
- Make rednet checks a little more strict - rednet.close(false) is no
longer valid.
- Error when attempting to redirect the terminal to itself
(term.redirect(term)).
Actually, many *globs*. It additionally prints the glob if no files
matched it, since that's clearer.
Also move the ComputerTestDelegate's filesystem to be disk-based. This
is what actual computers use, and the MemoryMount is a little broken.
- os.time, when given a table, will act the same as PUC Lua - returning
the seconds since the epoch. We preserve the previous string/nil
behaviour though - os.epoch("local") is equivalent to PUC's
os.time().
- os.date will now act accept a string and (optional) time, returning
an appropriate table.
Somewhat resolves the madness which was dan200/ComputerCraft#183, and
hopefully (though probably not) makes @Vexatos happy.
- Share the ILuaContext across all method calls, as well as shifting it
into an anonymous class.
- Move the load/loadstring prefixing into bios.lua
- Be less militant in prefixing chunk names:
- load will no longer do any auto-prefixing.
- loadstring will not prefix when there no chunk name is supplied.
Before we would do `"=" .. supplied_program`, which made no sense.
For instance, `pastebin run https://pastebin.com/LYAxmSby` will now
extract the code and download appropriately. Also add an error message
when we received something which is not a valid pastebin code.
See #134.
This runs tests on CraftOS using a tiny test runner that I originally
knocked up for LuaDash. It can be run both from JUnit (so IDEA and
Gradle) and in-game in the shell, so is pretty accessible to work with.
I also add a very basic POC test for the io library. I'd like to flesh
this out soon enough to contain most of the things from the original io
test.
