From 489f61aa4c21a94e664632919577c91abdba89be Mon Sep 17 00:00:00 2001 From: wm4 Date: Fri, 10 Feb 2012 19:03:24 +0100 Subject: commands: add pt_clear command to clear playlist This deletes all playlist elements, except the currently active playlist entry. NOTE: this doesn't remove parent nodes in the case when we really have a play tree (as opposed to a play list). Apparently this doesn't cause any harm. --- command.c | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) (limited to 'command.c') diff --git a/command.c b/command.c index 8c5d02e81d..fab9ccabd7 100644 --- a/command.c +++ b/command.c @@ -21,6 +21,7 @@ #include #include #include +#include #include "config.h" #include "talloc.h" @@ -2787,6 +2788,28 @@ static void remove_subtitle_range(MPContext *mpctx, int start, int count) } } +static void do_clear_pt(struct play_tree *node, struct play_tree *exclude) +{ + while (node) { + do_clear_pt(node->child, exclude); + struct play_tree *next = node->next; + // do not delete root node, or nodes that could lead to "exclude" node + if (node->parent && !node->child && node != exclude) + play_tree_remove(node, 1, 1); + node = next; + } +} + +static void clear_play_tree(MPContext *mpctx) +{ + struct play_tree *exclude = NULL; + if (mpctx->playtree_iter) { + assert(mpctx->playtree == mpctx->playtree_iter->root); + exclude = mpctx->playtree_iter->tree; + } + do_clear_pt(mpctx->playtree, exclude); +} + void run_command(MPContext *mpctx, mp_cmd_t *cmd) { struct MPOpts *opts = &mpctx->opts; @@ -3116,6 +3139,10 @@ void run_command(MPContext *mpctx, mp_cmd_t *cmd) break; } + case MP_CMD_PLAY_TREE_CLEAR: + clear_play_tree(mpctx); + break; + case MP_CMD_STOP: // Go back to the starting point. while (play_tree_iter_up_step(mpctx->playtree_iter, 0, 1) != -- cgit v1.2.3
