table.save error.

[Lofn]

Hi guys! I'm trying to get table.save to function properly after having issues with saveVars() and tables nested in tables, and I'm running into an error when I try to call it. For testing, I wrote up this and stuck it in a script file by itself:

Code: Select all

test_table = {"foo","bar","november 5th"}

function Load()
echo("Loading table.\n")
table.load("testtable.txt",test_table)
echo("Table loaded.\n")
end

function Save()
	echo("Saving table.\n")
	table.save("testtable.txt",test_table)
	echo("Table saved.\n")
end

When I try and use Save(), I get the following error:

Code: Select all

 [ERROR:] object:<run_code> function:<Alias27>
         <[string "--[[..."]:66: bad argument #1 to 'open' (string expected, got table)>

(for clarity, run_code is an alias that runs anything after a /)
I'm not sure what I'm doing wrong, or if it's right in front of me, or what.

table.save() and table.load() are the standard functions for user data persistency in Mudlet. They are pretty straight forward to use: Here's a little demo:

Code: [show] | [select all] lua

itemTable = {"rapier","pants","fish", nestedTableExample={"nested1", "nested2", "nested3"}}
echo("original table:\n")
display(itemTable)
table.save("test_itemTable", itemTable);

itemTable = {"foo", "bar"}
echo("table changed to:\n")
display(itemTable)
table.load("test_itemTable", itemTable)
echo("tabled restored from file to:\n")
display(itemTable)

This will get you this output:

Code: [show] | [select all] lua

original table:

table {
  1: 'rapier'
  2: 'pants'
  3: 'fish'
  'nestedTableExample': table {
    1: 'nested1'
    2: 'nested2'
    3: 'nested3'
  }
}
table changed to:

table {
  1: 'foo'
  2: 'bar'
}
tabled restored from file to:

table {
  1: 'rapier'
  2: 'pants'
  3: 'fish'
  'nestedTableExample': table {
    1: 'nested1'
    2: 'nested2'
    3: 'nested3'
  }
}

I can't comment on your alias problem, because you haven't provided any code of the alias script

Just adding keywords for people searching for this:

saveVars()
remember()
remember("")
loadVars()

P.S. I've noticed other stuff in 1.1 that doesn't correspond to the manual exactly, like db:fetch_database(""), which throws a "attempt to call method 'fetch_database' (a nil value)" error in 1.1, like the above-mentioned non-working saveVars() in 1.1.
