to finish!! and then make better (through experience and nicking good ideas from the forums)

to do/check:

  • FAT problem?
  • prince sign o the times, bjork. trentemoller, cruxshadows
  • QT5 BUG - cannot copy and paste from here to picard without characters being altered!! - ISSUE WITH SWAY/WAYLAND - use X11/xwayland
  • separate disc directories

Problem with detecting a ""Various Artists"" disc - some releases do not use "Various Artists" for their %albumartist%, e.g., Fabric and Fabriclive DJ mix CDs.

Also, %albumartist% is equal to %artist% for regular %artist% releases.

Methods:

  • Detect if %albumartist% equals "Various Artists"
$eq(x,y)
  # Returns true if x equals y.
$eq(%musicbrainz_albumartistid%,89ad4ac3-39f7-470e-963a-56509c546377)
  • Detect if %releasetype% contains "compilation" or "dj-mix"
  • Detect if %djmixer% contains anything.
$in(x,y)
  # Returns true, if x contains y.

$inmulti(%x%,y)
  # Returns true if multi-value variable x contains exactly y as one of its values. 
$eq_any(x,a1,a2...)
  # Returns true if x equals a1 or a2 or ... 

$or(x,y,*args)
  # Returns true if either x or y not empty. Can be used with an arbitrary number of args.

$ne(x,y)
  # Returns true if x does not equal y.

$or($inmulti(%releasetype%,compilation),$inmulti(%releasetype%,dj-mix),$ne(%djmixer%,))


$or($eq(%musicbrainz_albumartistid%,89ad4ac3-39f7-470e-963a-56509c546377),$inmulti(%releasetype%,compilation),$inmulti(%releasetype%,dj-mix),$ne(%djmixer%,))


$if(if,then,else)
  # If if is not empty, it returns then, otherwise it returns else.


$if($or($eq(%musicbrainz_albumartistid%,89ad4ac3-39f7-470e-963a-56509c546377),$inmulti(%releasetype%,compilation),$inmulti(%releasetype%,dj-mix),$ne(%djmixer%,)),%albumartist%,%artist%)


$rreplace(text,pattern,replace)
  # Regular expression replace.


chars to remove: ’`'”-/\|;:*?!&[]{}<>,.$

special consideration:

  • \ needs to be \\\\ to escape for both Picard and Python
  • , needs to be \, because , is used to delineate arguments in $rreplace
  • . needs to be \.
  • $ needs to be \$
  • * needs to be \*
  •  ? needs to be \?
  • { needs to be \{
  • [ needs to be \[
  • | needs to be \|
  • ( needs to be \(
  • - needs to be \- because - is used in [5b-d] for 'between'

[’`'”\-/\\\\\|;:\*\?!&\[\]\{\}<>\,\.\$]

in progress mess:


Outer folder:

$replace($validate($if(%albumartist%,%albumartist%,%artist%),,’`'”-/\|;:*?!&\[]{}<>,.)," ","_")

becomes

$set(_releaseartist,$replace($rreplace($if($or($eq(%musicbrainz_albumartistid%,89ad4ac3-39f7-470e-963a-56509c546377),$inmulti(%releasetype%,compilation),$inmulti(%releasetype%,dj-mix),$ne(%djmixer%,)),%albumartist%,%artist%),[’`'”\-/\\\\\|;:\*\?!&\[\]\{\}<>\,\.\$],) ,_))

%_releaseartist%

/

Release folder:

$set(_releasealbum,$replace($rreplace(%album%,[’`'”\-/\\\\\|;:\*\?!&\[\]\{\}<>\,\.\$],) ,_))

%_releaseartist%-%date%-%_releasealbum%

/

Track file:

$replace($validate($if(%albumartist%,%albumartist%,%artist%),,’`'”-/\|;:*?!&\[]{}<>,.)," ","_")-%year%-$replace($validate(%album%,,’`'”-/\|;:*?!&\[]{}<>,.)," ","_")-$num(%track%,2)$if(%albumartist%,-$replace($validate(%artist%,,’`'”-/\|;:*?!&\[]{}<>,.)," ","_"),)-$replace($validate(%title%,,’`'”-/\|;:*?!&\[]{}<>,.)," ","_")

becomes

$set(_releasetracknum,$if($gt(%totaldiscs%,1),%discnumber%-,)$num(%tracknumber%,$if($gt(%totaltracks%,99),3,2)))

$set(_releasetrack,$replace($rreplace(%title%,[’`'”\-/\\\\\|;:\*\?!&\[\]\{\}<>\,\.\$],) ,_))

%_releasetracknum%-%_releasetrack%

So:

$set(_releaseartist,$replace($rreplace($if($or($eq(%musicbrainz_albumartistid%,89ad4ac3-39f7-470e-963a-56509c546377),$inmulti(%releasetype%,compilation),$inmulti(%releasetype%,dj-mix),$ne(%djmixer%,)),%albumartist%,%artist%),[’`'”\-/\\\\\|;:\*\?!&\[\]\{\}<>\,\.\$],) ,_))

%_releaseartist%/

$set(_releasealbum,$replace($rreplace(%album%,[’`'”\-/\\\\\|;:\*\?!&\[\]\{\}<>\,\.\$],) ,_))

%_releaseartist%-%date%-%_releasealbum%/

$set(_releasetracknum,$if($gt(%totaldiscs%,1),%discnumber%-,)$num(%tracknumber%,$if($gt(%totaltracks%,99),3,2)))
$set(_releasetrack,$replace($rreplace(%title%,[’`'”\-/\\\\\|;:\*\?!&\[\]\{\}<>\,\.\$],) ,_))

%_releasetracknum%-%_releasetrack%


then I added more stuff


then I added

$num(%discnumber%,$if($gt(%totaldiscs%,9),2,1))-,)

Path ends up like

See Workings and Oldercrap for what this means


Remember to:

  • avoid blank years
  • avoid blank album/artist names
  • check if some album artists should be "Various Artists" or a performer/DJ/curator name
  • essentially all these are fixed by *carefully* running directories through MusicBrains prior


Testing

not working:

$regex($regex($if(%albumartist%,%albumartist%,%artist%),’`'”-*\?!&/\|\\\(\)\[]\{\}<>;:,\.,),\s,_)/$regex($regex($if(%albumartist%,%albumartist%,%artist%)-%year%-%album%,’`'”-*\?!&/\|\\\(\)\[]\{\}<>;:,\.,),\s,_)/$regex($regex($if(%albumartist%,%albumartist%,%artist%)-%year%-%album%-$num(%track%,2)$if(%albumartist%,-%artist%,)-%title%,’`'”-*\?!&/\|\\\(\)\[]\{\}<>;:,\.,),\s,_)

to fix ^
   puddlestuff.findfunc.ParseError: SYNTAX ERROR in $regex: unbalanced parenthesis ???
vim-script shows balanced parens


Further issues(?):

  • double __?
  • remove accidental trailing whitespace?

Workings

Be careful when copying and pasting the above - a new line character might be added to the end.

Produces directory path and filenames like this:

/media/3tb/media/music/FLAC/Decapitated/Decapitated-2000-04-17-Winds_of_Creation/Decapitated-2000-04-17-Winds_of_Creation-05-Decapitated-The_Eye_of_Horus.flac


$validate(%title%,,’`'”-/\|;:*?!&\[]{}<>,.)

Cannot validate away ( or ) with the above method. Two regexs instead of validate and replace would allow changing ( and ). One for removing, one for underscores.

Functions cannot be applied across directory boundaries.


$regex(text, regex, repl, matchcase=0)

  Replaces all occurrences of regex with repl in text.
   text: text to search, eg. %artist%
   regex: regular expression to use as the search eg. jay.*
   repl: Text to replace all matches of regex with. Can be pattern ex $lower($1), but has to be quoted like in “$lower($1)” otherwise any scripting functions used will be run before the regular expression is evaluated.
   matchcase: Defaults to 0. If 1, will have case-sensitive matching.

's/ /_/g'
$regex(,\s,_)

chars to remove:
’`'”-*?!&/|\()[]{}<>;:,.

unescaped:
$regex(,’`'”-*?!&/|\()[]{}<>;:,.,)

regex control chars:
[\^$.|?*+(){} 
     not used: regex to make string filesystem safe?: ^(/)?([^/\0]+(/)?)+$ 
escaped:
$regex(,’`'”-*\?!&/\|\\\(\)\[]\{\}<>;:,\.,)

within removal of spaces
$regex($regex(,’`'”-*\?!&/\|\\\(\)\[]\{\}<>;:,\.,),\s,_)
       |                                         |

$if(%albumartist%,%albumartist%,%artist%)-%year%-%album%/
$if(%albumartist%,%albumartist%,%artist%)-%year%-%album%-$num(%track%,2)$if(%albumartist%,-%artist%,)-%title%


Older crap

basic formatting tests (see bottom for final);

Puddletag directory spaces to _:
$replace($validate(%artist%,,’`'/\*?;”|:)," ","_")/$replace($validate(%artist%,,’`'/\*?;”|:)," ","_")-%year%-$replace($validate(%album%,,’`'/\*?;”|:)," ","_")

Puddletag file spaces to _:

 Puddletag directory remove spaces:
$validate($if(%albumartist%,%albumartist%,%artist%),,’`'/\*?;”|: )/$validate($if(%albumartist%,%albumartist%,%artist%),,’`'/\*?;”|: )-%year%-$validate(%album%,,’`'/\*?;”|: )/


 Puddletag file remove spaces:
$validate($if(%albumartist%,%albumartist%,%artist%),,’`'/\*?;”|: )-$if($neql(%artist%,%albumartist%),%artist%-,)%year%-$validate(%album%,,’`'/\*?;”|: )-$num(%track%,2)-$validate(%title%,,’`'/\*?;”|: )

$validate($if(%albumartist%,%albumartist%,%artist%),,’`'/\*?;”|: )-$if($neql(%artist%,%albumartist%),%artist%-,)%year%-$validate(%album%,,’`'/\*?;”|: )-$num(%track%,2)-$validate(%title%,,’`'/\*?;”|: )


redo:
%artist%/%artist%-%year%-%album%/ %artist%-%year%-%album%-%track%-%title%
%albumartist%/%albumartist%-%year%-%album%/ %albumartist%-%year%-%album%-%track%-%artist%-%title%

$if(%albumartist%,%albumartist%,%artist%)/$if(%albumartist%,%albumartist%,%artist%)-%year%-%album%/$if(%albumartist%,%albumartist%,%artist%)-%year%-%album%-%track%$if(%albumartist%,-%artist%,)-%title%


$validate(,,’`'”-/\|;:*?!&\[]<>,.)


Schema: albumartist = various artists compilation album. An if to see if albumartist and artist is different would fail for compilations including a track by the album artist.


Final:

 Puddletag file remove spaces + albumartist ifs:
$validate($if(%albumartist%,%albumartist%,%artist%),,’`'/\*?;”|: -&\[],.)/$validate($if(%albumartist%,%albumartist%,%artist%),,’`'/\*?;”|: -&\[],.)-%year%-$validate(%album%,,’`'/\*?;”|: -&\[],.)/$validate($if(%albumartist%,%albumartist%,%artist%),,’`'/\*?;”|: -&\[],.)-%year%-$validate(%album%,,’`'/\*?;”|: -&\[],.)-$num(%track%,2)$if(%albumartist%,-$validate(%artist%,,’`'/\*?;”|: -&\[],.),)-$validate(%title%,,’`'/\*?;”|: -&\[],.)

New final:

 Puddletag file spaces to underscores + albumartist ifs:
$replace($validate($if(%albumartist%,%albumartist%,%artist%),,’`'/\*?;”|:-&\[],.)," ","_")/$replace($validate($if(%albumartist%,%albumartist%,%artist%),,’`'/\*?;”|:-&\[],.)," ","_")-%year%-$replace($validate(%album%,,’`'/\*?;”|:-&\[],.)," ","_")/$replace($validate($if(%albumartist%,%albumartist%,%artist%),,’`'/\*?;”|:-&\[],.)," ","_")-%year%-$replace($validate(%album%,,’`'/\*?;”|:-&\[],.)," ","_")-$num(%track%,2)$if(%albumartist%,-$replace($validate(%artist%,,’`'/\*?;”|:-&\[],.)," ","_"),)-$replace($validate(%title%,,’`'/\*?;”|:-&\[],.)," ","_")


How does evaluation work? test:

$replace($validate($if(%albumartist%,%albumartist%,%artist%)/$if(%albumartist%,%albumartist%,%artist%)-%year%-%album%/$if(%albumartist%,%albumartist%,%artist%)-%year%-%album%-%track%$if(%albumartist%,-%artist%,)-%title%,,’`'/\*?;”|:-&\[],.)," ","_")

Ah, evaluation stops at directory slashes.


Issues(?):

  • double __?
  • remove accidental trailing whitespace?
  • paren brackets
