From d41e7f7cec3b4000ffc41d91ef1a612937a04625 Mon Sep 17 00:00:00 2001 From: Jochen Keil Date: Mon, 30 Mar 2009 21:44:41 +0200 Subject: Build tags from information in cue sheets With these methods a tag struct can be created from the cdtext information in a cue sheet. The methods depend on a cue parsing library. Reading from strings (char*) as well as from a file (FILE*) is supported. --- src/cue/cue_tag.c | 276 ++++++++++++++++++++++++++++++++++++++++++++++++++++++ src/cue/cue_tag.h | 20 ++++ 2 files changed, 296 insertions(+) create mode 100644 src/cue/cue_tag.c create mode 100644 src/cue/cue_tag.h (limited to 'src/cue') diff --git a/src/cue/cue_tag.c b/src/cue/cue_tag.c new file mode 100644 index 00000000..ce8202a8 --- /dev/null +++ b/src/cue/cue_tag.c @@ -0,0 +1,276 @@ +#include "cue_tag.h" + +static struct tag* +cue_tag_cd(struct Cdtext* cdtext, struct Rem* rem) +{ + char* tmp = NULL; + struct tag* tag = NULL; + + //if (cdtext == NULL) + //return NULL; + + tag = tag_new(); + + tag_begin_add(tag); + + { /* TAG_ITEM_ALBUM_ARTIST */ + if ((tmp = cdtext_get(PTI_PERFORMER, cdtext)) != NULL) + tag_add_item(tag, TAG_ITEM_ALBUM_ARTIST, tmp); + + else if ((tmp = cdtext_get(PTI_SONGWRITER, cdtext)) != NULL) + tag_add_item(tag, TAG_ITEM_ALBUM_ARTIST, tmp); + + else if ((tmp = cdtext_get(PTI_COMPOSER, cdtext)) != NULL) + tag_add_item(tag, TAG_ITEM_ALBUM_ARTIST, tmp); + + else if ((tmp = cdtext_get(PTI_ARRANGER, cdtext)) != NULL) + tag_add_item(tag, TAG_ITEM_ALBUM_ARTIST, tmp); + /* TAG_ITEM_ALBUM_ARTIST */ } + + { /* TAG_ITEM_ARTIST */ + if ((tmp = cdtext_get(PTI_PERFORMER, cdtext)) != NULL) + tag_add_item(tag, TAG_ITEM_ARTIST, tmp); + + else if ((tmp = cdtext_get(PTI_SONGWRITER, cdtext)) != NULL) + tag_add_item(tag, TAG_ITEM_ARTIST, tmp); + + else if ((tmp = cdtext_get(PTI_COMPOSER, cdtext)) != NULL) + tag_add_item(tag, TAG_ITEM_ARTIST, tmp); + + else if ((tmp = cdtext_get(PTI_ARRANGER, cdtext)) != NULL) + tag_add_item(tag, TAG_ITEM_ARTIST, tmp); + /* TAG_ITEM_ARTIST */ } + + /* TAG_ITEM_PERFORMER */ + if ((tmp = cdtext_get(PTI_PERFORMER, cdtext)) != NULL) + tag_add_item(tag, TAG_ITEM_PERFORMER, tmp); + + /* TAG_ITEM_COMPOSER */ + if ((tmp = cdtext_get(PTI_COMPOSER, cdtext)) != NULL) + tag_add_item(tag, TAG_ITEM_COMPOSER, tmp); + + /* TAG_ITEM_ALBUM */ + if ((tmp = cdtext_get(PTI_TITLE, cdtext)) != NULL) + tag_add_item(tag, TAG_ITEM_ALBUM, tmp); + + /* TAG_ITEM_GENRE */ + if ((tmp = cdtext_get(PTI_GENRE, cdtext)) != NULL) + tag_add_item(tag, TAG_ITEM_GENRE, tmp); + + /* TAG_ITEM_DATE */ + if ((tmp = rem_get(REM_DATE, rem)) != NULL) + tag_add_item(tag, TAG_ITEM_DATE, tmp); + + /* TAG_ITEM_COMMENT */ + if ((tmp = cdtext_get(PTI_MESSAGE, cdtext)) != NULL) + tag_add_item(tag, TAG_ITEM_COMMENT, tmp); + + /* TAG_ITEM_DISC */ + if ((tmp = cdtext_get(PTI_DISC_ID, cdtext)) != NULL) + tag_add_item(tag, TAG_ITEM_DISC, tmp); + + /* stream name, usually empty + * tag_add_item(tag, TAG_ITEM_NAME,); + */ + + /* REM MUSICBRAINZ entry?
