Reloading config on signal

[disarmer]

Hi!
Is there are ways to reload config properly? I'm trying to change font of working tilda instance by reloading config on SIGHUP or other signal(like in nginx), but i have no idea how to apply visual settings due my poor C skill.

static void termination_handler (G_GNUC_UNUSED gint signum) {
    if (signum == SIGHUP) {
        DEBUG_FUNCTION ("reload_handler");
        gint instance = get_instance_number ();
        gchar *config_file = get_config_file_name (instance);
        DEBUG_FUNCTION (config_file);
        config_init (config_file);
        parse_cli (0,*"");
    } else {
        DEBUG_FUNCTION ("termination_handler");
        gtk_main_quit ();
   }
}

It works, but window appearance didn't change

Hi,

updating the config does not necessarily change the value for the current application. Because the callbacks are not called, check wizard.c to see which functions is responsible for initializing the config, you probably also need to call that function.

Hi,

I checked again, the function which updates the font is button_font_font_set_cb in wizard.c. Here is the function trace:

button_font_font_set_cb()
connect_wizard_signals()
wizard()

Only wizard() is visible outside of wizard.c, so you will probably want to move the following code out of button_font_font_set_cb and into a new function, so you can call it from outside wizard.c:

for (i=0; i<g_list_length (tw->terms); i++) {
    tt = g_list_nth_data (tw->terms, i);
    PangoFontDescription *description =
        pango_font_description_from_string (font);
    vte_terminal_set_font (VTE_TERMINAL(tt->vte_term), description);
}

Yeah, i'm found it too, but i don't know how to pass tilda_tindow tw to signal handler. Only global variable? But it's ugly

Take a look at: http://stackoverflow.com/questions/6970224/providing-passing-argument-to-signal-handler

There is no other way.
