Erasing Saves in Harlowe 1.1

bphennessy

So I'm using the new version of Harlowe (which seems awesome by the way) and I want to add save functionality to the game I'm working on. One thing I'm not sure on, though: is it possible to ERASE a player's save?

Currently the only way to erase a savefile is to save a new file over the same name - but a deletion macro could be added in the future.

Hmmm... okay so let's say I have a single save file which I've made with (savegame: "XYZ", "A REAL SAVE"). I can overwrite that save by going (savegame: "XYZ", "DELETED") at some other point, right? If I did that, would I then be able to only display the "Load Game" option if (savedgames:) contains "A REAL SAVE"? In other words, "erasing" the file by preventing the option to load it?

As in:

(if: (savedgames:) contains "A REAL SAVE")[blah blah blah link to a passage with loadgame in it]

Or does that contains thing only work with slot names and not filenames?

Datamaps consist of key->value pairs. The "contains" operator only checks keys in datamaps, and the datamap produced by (savedgames:) has slotnames in key position, with filenames in value position. So, that won't work.

HOWEVER, you can use the brand new (datavalues:) macro to put all the datamap's values into an array, and then use "contains" on it:

(if: (datavalues: (savedgames:)) contains "A REAL SAVE")[blah blah blah link to a passage with loadgame in it]

This should work as you hope.

Whee. Thanks.
