4 abcde uses a lot of files as it runs in order to keep track of current
5 status and to store the various bits of data it's using, like cddb
6 lookups and results, user choices, encoding etc.
8 Here is (the start of!) a quick guide to what each file is used
9 for. Each file lives in $ABCDETEMPDIR at runtime, which is the
10 per-disc working directory that abcde uses. Once the "clean" operation
11 has happened, they all go away.
16 cddbchoices - concatenation of all the lookups with some status
17 information. Displayed to the user once all the lookups
18 are complete, as the list of results to choose from.
20 cddbread.X - generic-ish results from a disc lookup, for match number
21 X. Based on the format used by *cddb*, but the
22 musicbrainz and cdtext lookup methods have been written
23 to (roughly) output this format as an interface so the
24 rest of the abcde code doesn't need massive adaptation
25 to new formats. Match number 0 is special - it's a blank
26 template file ready for the user to edit in case there's
29 datasource.X- text label for the source of the data in cddbread.X,
30 e.g. "cddb" or "Musicbrainz". Generated by the data
31 lookup methods, then used later if we care where the
34 cddbquery.X - Summary of a single disc lookup result. Based on the
35 complicated format used by *cddb*, but without the
36 result code. Generated by the data lookup methods, then
37 used later to fabricate a composite cddbquery file.
39 cddbquery - result code and summary of a disc lookup. Based on the
40 format used by *cddb*, and faked up by the other lookup
41 methods. A single successful match will look like:
43 200 $genre $discid $artist / $album
45 Multiple successful matches will show up as
47 210 Found exact matches, list follows (until terminating `.')
48 $genre1 $discid $artist1 / $album1
49 $genre2 $discid $artist2 / $album2
52 Other response codes are possible, 999 is special and
53 used internally by abcde to denote a local cddb data
56 cue-<discid>.txt - cue file generated from the track data on the disc
58 cddbdiscid - raw data showing the cddb discid and the track info numbers
61 mbdiscid - raw data showing a musicbrainz discid and the track info
62 numbers used to calculate it
64 status - log file of all the operations carried out thus far. Format
65 is important - things are looked up here regularly to
66 work out what's happened and what should be done
67 next. See usage of the checkstatus() function to look
70 Files specific to lookups using *cddb*, in the data-cddb subdir:
72 * cddbstat - status from a cddb server, downloaded as a check that
73 the server is working correctly (ish!)
75 Files specific to lookups using *musicbrainz*:
77 * asin.X -\ details about musicbrainz-specific information for
78 * mbid.X -/ match number X.
80 specific to lookups using *cdtext*, in the data-cdtext subdir:
82 * cd-text - the raw CD-Text information as returned by icedax/cdda2wav
