NAME

       pytagsfs - filesystem mapping media files to an arbitrary directory structure

SYNOPSIS

       pytagsfs [OPTIONS] {sourcedir} {mountpoint}

DESCRIPTION

       pytagsfs is a FUSE filesystem that was designed to present multiple views of tagged media
       files. For instance, a directory tree containing audio files could be mapped to a new
       directory structure organizing those same files by album, genre, release date, etc.

       To get a feel for what's possible, see the section called “EXAMPLES”.

       Log messages are kept in a limited-size ring buffer in memory, and can be read from the
       virtual file named ".log", under the mount point root.

OPTIONS

       --version
           show version of program and exit

       -h, --help
           show summary of options and exit

       -f
           foreground operation

       -d
           enable debug output (implies -f)

       -s
           disable multi-threaded operation

       -r
           mount read-only

       -o opt[,opt...]
           mount options

       -o format=FORMAT
           format string for destination paths (see the section called “FORMAT STRINGS”)

       -o srcfilter=EXPR
           adds a source path filter; may be specified more than once (see the section called
           “PATH FILTERS”)

       -o dstfilter=EXPR
           adds a destination path filter; may be specified more than once (see the section
           called “PATH FILTERS”)

       -o iocharset=ENCODING
           mounted tree character encoding (default utf-8)

       -o source_iocharset=ENCODING
           source directory character encoding (default utf-8)

       -o ro
           synonym for -r (Linux)

       -o rdonly
           synonym for -r (Darwin, FreeBSD, NetBSD, OpenBSD)

       -o allow_other
           allow access to other users

       -o allow_root
           allow access to root

       -o nonempty
           allow mounts over non-empty file/dir

       -o uid=UID
           set file owner

       -o gid=GID
           set file group

       -o verbosity=VERBOSITY

           synonym for -d

       -o force_write_support
           Force write support on systems that are not known to have correct mmap semantics. This
           option is dangerous and can lead to file corruption with some applications on some
           systems!

FORMAT STRINGS

       A format string must be specified for each pytagsfs mount. The format string specifies the
       structure of the virtual filesystem mount by defining a template for virtual paths. For
       instance, the following format string defines a virtual filesystem layout that organizes
       media files by artist, then by album, and, finally, by track name:

           /%{artist}/%{album}/%{track}.%{extension}

   Substitutions
       The format string should contain zero or more substitution sequences. Each such sequence
       begins with a percent sign (%).

       Substitution sequences may be specified in either long or short forms. Long-form
       substitution sequences are written as "%{KEY}", where KEY corresponds with a meta-data
       key. The set of available keys varies from file to file, however, many media files feature
       some or all of the following long keys:
           filename  name of the original file
           parent  name of the original file's parent directory
           extension  extension of the original file
           tracknumber  track number; concise (like 7)
           TRACKNUMBER  track number; two digits with leading zeros (like 07)
           artist  artist
           composer composer
           title  track title
           album  album title
           year  year of release
           genre  genre

       Short-form substitution sequences are written as "%X". Each such sequence is an
       abbreviation for a long-form sequence, as indicated below:
           f  filename
           p  parent
           e  extension
           n  number
           N  NUMBER
           a  artist
           c  composer
           t  title
           l  album
           y  year
           g  genre

   Modifiers
       Format strings can be further extended to perform string translations on parameters prior
       to substitution. Such translations are indicated by the inclusion of a modifier character
       after the percent sign. For instance, "%^a" indicates an all-caps version of the artist
       name, as does "%^{artist}".

       The full list of modifier characters follows:
           ^  UPPERCASE
           _  lowercase
           !  Title Case

   Conditional Expressions
       Normally, any file for which a parameter required by the format string cannot be
       determined is implicitly excluded from the resulting filesystem. Conditionals can be used
       to express that these files should be included, but that those portions of the format
       string that cannot be rendered should be omitted or replaced.

       Two types of conditional expressions may be used: "if" expressions and "if-else"
       expressions. The contents of an "if" expression are omitted unless all parameters within
       that expressions can be successfully evaluated. An "if-else" expression is similar, except
       that, if the expression does not evaluate, an alternative will be used instead. Use the
       following syntax:
           %?expr%?
           %?expr%:alt%?

PATH FILTERS

       Path filters can be used to limit the set of files presented by the filesystem using
       regular expressions. Files are filtered by source path or by destination path, inclusively
       (limiting the set of paths to those that match the regular expression) or exclusively
       (limiting the set of paths to those that do not match the regular expression).

       Use the mount options srcfilter and dstfilter to filter by source path and destination
       path, respectively. Filters are inclusive unless the filter parameter starts with an
       exclamation point, in which case the regular expression is assumed to be the part of the
       parameter following the exclamation point.

       Multiple filters of any kind may be used, and are applied in the order that they are
       specified on the command line. See the section called “EXAMPLES” for some sample filters.

EXAMPLES

       View media files in src, with original filenames in a flat directory structure:

           $ pytagsfs -o format='/%f' src mnt

       View media files in src by album on mnt:

           $ pytagsfs -o format='/%a/%f' src mnt

       A more complex album-based view:

           $ pytagsfs -o format='/%a - %l/%N %a - %t [%l].%e'

       This is like above, but filters the result. I use this to display my files by album, but
       exclude compilations (which I've tagged to include a hyphen in the album name, like
       "various - album"):

           $ pytagsfs -o \
             format='/%a - %l/%N %a - %t [%l].%e',\
             dstfilter='!^/[^/]* - [^/]* - [^/]*/' \
             src albums

       I use this to display the compilations:

           $ pytagsfs -o \
             format='/%l/%N %a - %t [%l].%e',\
             dstfilter='^/[^/]* - [^/]*/' \
             src compilations

       Maybe you only want to see files that start with "a" and end in ".mp3"?

           $ pytagsfs -o \
             format='/%f',dstfilter='^/a',dstfilter='\.mp3$' \
             src mnt

UNMOUNTING

       To unmount the filesystem on Linux use fusermount(1):

           $ fusermount -u mnt

       To unmount the filesystem on OS X or *BSD use umount(1):

           $ umount mnt
