Hey everyone, I am thinking of putting in a feature request for getting the parent directory. at the moment I have this code in my Application.cfc to create the mappings.

this.currentPath = getDirectoryFromPath(getCurrentTemplatePath());
this.delim = find("/", this.currentPath) ? "/" : "\";
this.basePath = listDeleteAt(this.currentPath, listLen(this.currentPath, this.delim), this.delim);
this.mappings["/coldspring"] = "#this.basePath#/cfmapping/coldspring/";

Which is fine and works great... But I have just installed testBox and it comes with its own Application.cfc - which I know I can do without... I don't need it - but as a default its application.cfc comes with similar code for creating the mappings... again all fine - but it is off by one directory. The very short version of all this is I would like to propose a new function for getting the "parent" directory - which would effectively just be - in CFML

listDeleteAt(this.currentPath, listLen(this.currentPath, this.delim), this.delim);

Thoughts?

I would thnk more useful would be a

listPop()

function. I was always a bit surprised that ACF added

listRest()

without a corresponding function to return a list without the last element. So:

listPop(this.currentPath, this.delim);

Would be the same as:

listDeleteAt(this.currentPath, listLen(this.currentPath, this.delim), this.delim);

At least then you have a generic function for just returning a list without the last item. It's not specific for directories.

yeah we have arrayPop, https://luceeserver.atlassian.net/issues/?jql=text%20~%20%22arrayPop%22%20ORDER%20BY%20updated file a ticket!

@dswitzer careful.

pop

would return the element, not the new list. Was gonna suggest that until I noticed that. But I would def go for an idiomatic approach to removing an item from a list as a generic treatment of this, more than I would get behind another path-monkeying function.

@Adam Cameron I agree - the more generic version would be better! So we need a list version of array.pop - then? For the moment I can keep on with what I am doing - or listToArray and use "pop" @zackster for the docs - how about?

moreMoreNumbers = [ ];
dump( ArrayPop( moreMoreNumbers, 44 ) ); // Outputs 44
dump( moreMoreNumbers ); // Outputs []
