$if() enhancement

I need some way to determine if a file contains a tag. As I understand, the method people use right now is to check if %title% or %album% or some other field exists, and if not, display %filename%.

But some of my files don't have an %album% field, and some don't have a %title% field (either could be unknown). They may have other fields that I wish to display. So as it is now, if the field I check for isn't there, it falls back to %filename%.

So I'd like something like: $if(tag=true,%foo%,%filename%).

This may not be the best explanation, but I hope you get the idea. If not, flame away.

Edit: Some clarification.

This is my string.

Quote
000080$num(%_playlist_number%,4). $if(%title%,$padcut($if(%artist%,%artist%,),30) '['$if(%date%,FF0000%date%,    )']' $padcut($if(%album%,%album%,),30) '['FF0000'#'$if(%tracknumber%,$num(%tracknumber%,2),  )']' $padcut($if(%title%,%title%,),30),808080%filename%) $if(%__replaygain_album_gain%,'['FF0000%__replaygain_track_gain%' / '%__replaygain_album_gain%']',)


And it yields the following result:

The whole title formatting string is wrapped in an $if() statement. And if it's false, it just displays the filename.

$if(tag=true,%foo%,%_filename%) is exactly how it works right now, if I'm not mistaken.

$if(%foo%,if foo exists display this,else display this) is $if()'s syntax.

and with $padcut() you don't have really need the "$if(%title%,insert main string,%_filename%) sub string" structure, as you can just do "$padcut(%artist%,20) $padcut(%date%,4) $padcut(%album%,30) $padcut(%tracknumber%,2) $if2(%title%,%_filename%) substring"

some other hints: instead of using $if(%foo%,Foo is %foo%,) you can use [Foo is %foo%]
instead of using $if(%foo%,%foo%,fallback text) you can use $if2(%foo%,fallback text)
'[''#' can be shortened into '[#'

$num(%_playlist_number%,4). $padcut(%artist%,30) '['$if2(%date%,    )']' $padcut(%album%,30) '[#'$if2($num(%tracknumber%,2),  )']' $if2($padcut(%title%,30),%_filename%) $if(%__replaygain_album_gain%,'['%__replaygain_track_gain%' / '%__replaygain_album_gain%']',)


You can change those $if2()s into $padcut()s. That, and integrating color codes, is left as an exercise for the reader : )

edit: oops. The above string isn't identical is it? I guess then you'll have to wrap the main string with $if() after all.

And you should substitute [%tag%] for $if(%tag,%tag,)

Hi folks,

On a related note, how does one test to see if an album is a various artists album, or if it is a single artist album?

If its a Various artists album, it should display as:

ALBUM - TRACK# - ARTIST - TITLE

If it is a single artist album, it would be:

ARTIST - ALBUM - TRACK# - TITLE


I would appreciate any and all suggestions.

Thanks.

use the $ifgreater and $strstr() commands.

Code: [Select]
$ifgreater($strstr(string,value), value, true, false)


$strstr params:
string - the string to check if value is contained within it
value - the value to check if contained in the string

$ifgreater params
$strstr() - anything can be used here that will produce a number
value - the value the number must be greater than
true - print this if the number is greater than the value
false - print this if the number is less than the value

for example if you have your VA albums stored in c:\music\albums\various\blah, you could do

Code: [Select]
$ifgreater($strstr(%_path%,various), 0, ALBUM - TRACK# - ARTIST - TITLE, ARTIST - ALBUM - TRACK# - TITLE)


the $strstr() will return a value greater than 0 if the string in the second param ("various" in this case) is contained in the first param ("%_path" in this case) and isn't at the start of the first param (eg "various\blah"=0 instead of "c:\various\blah"=3). Make sure there isn't a space between the comma and the string to check for.

Hope this helps

Krispy,

Thanks. I appreciate your reply. To use your method would mean that I would have to place all my VA albums in a folder with a name to test for, whether it is "Various" as in your ex. or anthing else.

My files are organised like this:

Single artist albums:
Code: [Select]
     
D:/MUSIC/ARTIST/ALBUM/artist - album - track# - title.mp3

VA albums
Code: [Select]
D:/MUSIC/ALBUM/album - track# - artist - title.mp3

If it is series of VA albums such as the Cafe Del Mar series (Vol. 1 to 9), then:
Code: [Select]
D:/MUSIC/CAFE DEL MAR/VOLUME #/album - track# -artist - title.mp3

Obviously, the test for a particular string in the path name would not work in this case, unless of course, I were to place all the VA albums into a separate folder.

It seems, to me anyway, that the only way to do it while keeping my files organised as they are, would be to use a tag field to store a value to test for. 

Again, thanks for your reply. You've given me some options to think about.

Wiske88,

i think you best option is probably to use a tag field to determine the differences, unless you want to use lots of $if statements (which would get rather ugly very quickly).
