I was working with a LocalSymbol, but after I deleted the cell I came back to the notebook hours later only to forget the name of the variable!
Is there anyway to see a full list of the named LocalSymbol objects that persist in a notebook?
I tried looking for them with Names[] but it doesn't show them.
I know of no better way than to just look in the local symbols directory. While it's not necessarily true that all local symbols are stored there, it should be true of the defaults (that is, those made as LocalSymbol["name"]).
Now, $LocalSymbolBase is a string with a protocol prefix (presumably to match it up with $CloudSymbolBase, although since that is a CloudObject anyway, I'm not sure that the matching-up is very good). Therefore, we can't SetDirectory to it immediately. I don't know of a way to get rid of that using a built-in, so I'll just do the following:
removePrefix[str_String] := If[StringTake[str, 7] === "file://", StringTake[str, 8;;], str]
Then the function you want is:
Module[{ret},
SetDirectory[removePrefix@$LocalSymbolBase];
ret = FileNames[];
ResetDirectory[];
ret
]
There is another way to view the local symbol directory that you might try.
SystemOpen[$LocalSymbolBase]
On my system, OS X, this opens a Finder window showing the folder containing the currently existing local symbols.
FileNames[$LocalSymbolBase]should get most of them. $\endgroup$In[7]:= LocalSymbol["ab"] = 1 Out[7]= 1 In[8]:= FileNames[$LocalSymbolBase] Out[8]= {}$\endgroup$FileNamesdoesn't do what I remembered it doing.SetDirectory[$LocalSymbolBase]; FileNames[]would work instead, except that for some unearthly reason$LocalSymbolBasehas a protocol on the front, so it isn't directly a directory. $\endgroup$SetDirectory::cdir: Cannot set current directory to file:///Users/Library/Wolfram/Objects/LocalSymbols. >>$\endgroup$file://protocol from the front. $\endgroup$
