Fetch from emusic using .emx files http://bitbucket.org/kenko/getemx
|Latest on Hackage:||0.1|
This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
getemx reads the .emx files used by `Emusic
<http://www.emusic.com>`_ and downloads the files they describe. Its
behavior is controlled by the file ~/.emxdownloader, which contains
instructions for file naming, art downloading, etc (see below in
`Invocation`_). It downloads files using either wget, curl, or
Haskell's interface to libcurl (though I would be surprised if anyone
who had libcurl installed didn't also have the curl binary).
Building & Installation
It should be possible to build and install getemx using `cabal
getemx accepts no options on the command line. Its arguments should
consist simply of .emx files; the simplest way to invoke it is::
$ getemx *.emx
where the .emx files are in the current directory.
getemx will read a file in your home directory called ".emxdownloader"
which can define options to control its behavior. Options may either
be *boolean* or *string*; the values of boolean options must be one of
"f", "t", "false", or "true" while string options may be any
string. The syntax of the .emxdownloader file is very simple::
option = value
Any amount of whitespace may occur before or after the "=". The
following are boolean options:
- **replace_underscores**: if true, underscores in the filename will be replaced by spaces. True by default.
- **replace_apostrophe_identity**: if true, the string "``'``" in filenames will be replaced by "``'``". True by default.
- **get_art**: if true, cover art will be downloaded for each album. True by default.
Currently the only string options control the filenames of the
downloaded files. There are two classes here: **dldir** specifies a
directory *relative to which* further processing will take place,
while **dlfmt** and **dlfmt_multidisc** specify how to process
*individual files*. The latter two accept a number of replacement
**Format string:** **Replaced by:**
``%(a)`` Artist name
``%(A)`` Album name
``%(n)`` Track number
``%(t)`` Track name
``%(D)`` Total number of discs in set
``%(d)`` Number of present disc in set (e.g. 2 out of 4)
``%(e)`` File extension
The defaults for the string options are:
- **dldir**: ``.``
- **dlfmt**: ``%(a)/%(A)/%(a) - %(A) - %(n) - %(t)``
- **dlfmt_multidisc**: ``%(a)/%(A): %(d)/%(a) - %(A): %(d) - %(n) - %(t)``
**dlfmt_multidisc** is used if a track is being downloaded that
belongs to a set with more than one disc; otherwise, **dlfmt** is
used. Note that at present the default for dlfmt_multidisc will
probably do the wrong thing on OS X. Note also that neither of the
default values ends with ``%(e)``: the file extension is supplied
automatically if it is not explicitly specified.
A ~/.emxdownloader file that set every option to its default value
could look like this::
get_art = t
replace_underscores = t
replace_apostrophe_identity = t
dldir = .
dlfmt = %(a)/%(A)/%(a) - %(A) - %(n) - %(t)
dlfmt_multidisc = %(a)/%(A): %(d)/%(a) - %(A): %(d) - %(n) - %(t)
"Could" because one could also write "true" out in full for "t".
