* Add digiline detector tube
The digiline detector tube outputs an itemstring of every stack
that passes through it on the channel specified in its formspec.
* Don't store digiline detector tube's formspec in a temporary local
The table lookup will fail if node.param2 is outside [0-3] which
is easily possible since there are several ways to modify param2
values of nodes. Force truncating param2 to always be 0-3 before
using it in a table lookup.
Before, init.lua called io.open on
pipeworks.worldpath..'/pipeworks_settings.txt'
to see if it existed, but did not close the resulting file handle if
it was found to exist. It instead erroneously called io.close() with
no argument, which does nothing if the default output file is set to
stdout, which it is.
Now, the result of io.open is saved to a local variable. If that value
is not nil (i.e. if the world settings file exists), the file handle is
passed to io.close before calling dofile.
Also, this saves pipeworks.worldpath..'/pipeworks_settings.txt' to a
local variable to reduce redundancy.
This adds a new type of Filter-Injector that waits for a digiline
message on its channel and then pulls the items described by the
message out of the inventory. It is basically a Stackwise Injector
that, on receiving a digiline message, sets its filter to the contents
of the digiline message and then activates itself.
Sending the message {name="default:brick", count=2} should do the
same thing as setting the filter of a Stackwise Filter-Injector to
two Brick Blocks and then punching it.
If no count is specified, it defaults to 1. Since this is based off
of the Stackwise Injector, it might make more sense if the default
were an entire stack. I can change this trivially.
You can also send requests like {{name="default:brick", count=1},
{name="default:dirt", count=1}}, which acts the same as setting the
filter to one Brick Block and one Dirt Block and then punching it.
If you send a string "default:dirt" instead of a table
{name="default:dirt"}, the string is passed to ItemStack and the
name and count are extracted from the resulting ItemStack. You can
also send a list of strings instead of tables: {"default:dirt",
"default:brick"}, and the first item found will be pulled.
Punching this or activating it with Mesecons currently does
nothing. I'm not really sure what would be the right thing to do in
either of those two cases, so I made it do nothing. I guess I could
make it use the previously-used filter, but I can't really see any
usefulness in that.
The recipe is probably too cheap. The darker of the two blue texture
colors could probably be better.
If we insert items through tubes, we must start the furnace timer
otherwise it will never start operating. This shouldn't break
older versions, as not having a timer function should just cancel
out.
