Problem with LOAD/SAVE and calculated fields?
« on: March 08, 2013, 09:33:37 am »

I've been using the following rules since variables were added to count the tracks in my albums:

[Media Type]=[Audio]
[=save(0,v_tracks[album artist (auto)][album])1]=1
[=save(math(1+load(v_tracks[album artist (auto)][album])),v_tracks[album artist (auto)][album])1]=1

The problem I've hit is that I want to account for the various versions of albums I have, eg remasters, in my collection and need to be able to differentiate between the various albums.  The above rule lumps them together because of the use of [album] (they all share the same title of course...)

So I added a user field that creates a constructed field and appends the year of the album release to the title so that I can generate unique album titles, eg

Same Album (1974)
Same Album (1993)
Same Album (2013)

BUT putting that calculated field into the code above breaks it.

First step.

Create a user field that combines the existing fields above in order to make things more readable.

[albumname]=[album artist (auto)][album]

So the above becomes:

[Media Type]=[Audio]
[=save(0,v_tracks[albumname])1]=1
[=save(math(1+load(v_tracks[albumname])),v_tracks[albumname])1]=1

This works correctly.

But now put some code into the field and it breaks.  For instance:

[albumname]=if(1,[album artist (auto)][album],[album artist (auto)][album])

You can display the [albumname] field correctly, but the load/save logic no longer works correctly?

Spent a couple of hours on this but cannot find a solution that works when using expressions?

Anybody?

It appears that the comma in the If() statement confounds the parsing of the variable name.

Simplifying, you can get good results setting albumname to:

   clean([album artist (auto)][album])

but bad results setting it to:

   clean([album artist (auto)][album],1)

So this seems like an expression parsing problem.
