From: Philip Chimento Date: Sat, 5 Feb 2011 00:48:11 +0000 (+0100) Subject: Clean up external Blorb file finding code X-Git-Tag: v0.9~143 X-Git-Url: https://git.stderr.nl/gitweb?p=projects%2Fchimara%2Fchimara.git;a=commitdiff_plain;h=fe6897c6c4a88491c1a760c6439156758ddbb8b0 Clean up external Blorb file finding code Moved the code that looks for an external Blorb file to the player, so the default path can become a setting in the preferences window. Also, passing an extra file name on the command line when starting the player also indicates an external resource file. --- diff --git a/libchimara/chimara-if.c b/libchimara/chimara-if.c index 2048f95..8c9de3c 100644 --- a/libchimara/chimara-if.c +++ b/libchimara/chimara-if.c @@ -67,6 +67,7 @@ typedef struct _ChimaraIFPrivate { ChimaraIFZmachineVersion interpreter_number; gint random_seed; gboolean random_seed_set; + gchar *graphics_file; /* Holding buffers for input and response */ gchar *input; GString *response; @@ -84,7 +85,8 @@ enum { PROP_TYPO_CORRECTION, PROP_INTERPRETER_NUMBER, PROP_RANDOM_SEED, - PROP_RANDOM_SEED_SET + PROP_RANDOM_SEED_SET, + PROP_GRAPHICS_FILE }; enum { @@ -166,6 +168,7 @@ chimara_if_init(ChimaraIF *self) priv->flags = CHIMARA_IF_TYPO_CORRECTION; priv->interpreter_number = CHIMARA_IF_ZMACHINE_DEFAULT; priv->random_seed_set = FALSE; + priv->graphics_file = NULL; priv->input = NULL; priv->response = g_string_new(""); @@ -217,6 +220,10 @@ chimara_if_set_property(GObject *object, guint prop_id, const GValue *value, GPa priv->random_seed_set = g_value_get_boolean(value); g_object_notify(object, "random-seed-set"); break; + case PROP_GRAPHICS_FILE: + priv->graphics_file = g_strdup(g_value_get_string(value)); + g_object_notify(object, "graphics-file"); + break; default: G_OBJECT_WARN_INVALID_PROPERTY_ID(object, prop_id, pspec); } @@ -252,6 +259,9 @@ chimara_if_get_property(GObject *object, guint prop_id, GValue *value, GParamSpe case PROP_RANDOM_SEED_SET: g_value_set_boolean(value, priv->random_seed_set); break; + case PROP_GRAPHICS_FILE: + g_value_set_string(value, priv->graphics_file); + break; default: G_OBJECT_WARN_INVALID_PROPERTY_ID(object, prop_id, pspec); } @@ -260,6 +270,8 @@ chimara_if_get_property(GObject *object, guint prop_id, GValue *value, GParamSpe static void chimara_if_finalize(GObject *object) { + CHIMARA_IF_USE_PRIVATE(object, priv); + g_free(priv->graphics_file); G_OBJECT_CLASS(chimara_if_parent_class)->finalize(object); } @@ -461,7 +473,21 @@ chimara_if_class_init(ChimaraIFClass *klass) g_param_spec_boolean("random-seed-set", _("Random seed set"), _("Whether the seed for the random number generator should be set manually"), FALSE, G_PARAM_READWRITE | G_PARAM_CONSTRUCT | G_PARAM_LAX_VALIDATION | G_PARAM_STATIC_STRINGS)); - + /** + * ChimaraIF:graphics-file: + * + * Some Z-machine interpreters accept an extra argument that indicates a + * separate Blorb file containing graphics and sound resources.
