Recursive icon lookup fails and no icon is shown`

[UtkarshVerma]

I have the following dunstrc.

My `dunstrc`

# See dunst(5) for all configuration options

[global]
    ### Display ###

    # Which monitor should the notifications be displayed on.
    monitor = 0

    # Display notification on focused monitor.  Possible modes are:
    #   mouse: follow mouse pointer
    #   keyboard: follow window with keyboard focus
    #   none: don't follow anything
    #
    # "keyboard" needs a window manager that exports the
    # _NET_ACTIVE_WINDOW property.
    # This should be the case for almost all modern window managers.
    #
    # If this option is set to mouse or keyboard, the monitor option
    # will be ignored.
    follow = keyboard

    ### Geometry ###

    # dynamic width from 200 to 400
    width = (200, 400)
    # constant width of 300
    # width = 300

    # The maximum height of a single notification, excluding the frame.
    height = (0, 300)

    # Position the notification in the top right corner
    origin = top-right

    # Offset from the origin

    # Scale factor. It is auto-detected if value is 0.
    scale = 0

    # Maximum number of notification (0 means no limit)
    notification_limit = 0

    ### Progress bar ###

    # Turn on the progess bar. It appears when a progress hint is passed with
    # for example dunstify -h int:value:12
    progress_bar = true

    # Set the progress bar height. This includes the frame, so make sure
    # it's at least twice as big as the frame width.
    progress_bar_height = 10

    # Set the frame width of the progress bar

    # Size of gap to display between notifications - requires a compositor.
    # If value is greater than 0, separator_height will be ignored and a border
    # of size frame_width will be drawn around each notification instead.

    gap_size = 0

    # Define a color for the separator.
    # possible values are:
    #  * auto: dunst tries to find a color fitting to the background;

    #  * anything else will be interpreted as a X color.

    # Sort messages by urgency.
    sort = yes

    # Don't remove messages, if the user is idle (no mouse or keyboard input)
    # for longer than idle_threshold seconds.

    # A client can set the 'transient' hint to bypass this. See the rules
    # section for how to disable this if necessary
    # idle_threshold = 120

    ### Text ###

    font = monospace 12

    # The spacing between lines.  If the height is smaller than the
    # font height, it will get raised to the font height.
    line_height = 0

    # Possible values are:

    #        <s>strikethrough</s>
    #        <u>underline</u>

    #        simplistic so using this option outside of matching rules for
    #        specific applications *IS GREATLY DISCOURAGED*.
    #
    # no:    Disable markup parsing, incoming notifications will be treated as
    #        plain text. Dunst will not advertise that it has the body-markup
    #        capability if this is set as a global setting.

    # regardless of what this is set to.

    ### Icons ###

    # Align icons left/right/off
    icon_position = left

    # Scale small icons up to this size, set to 0 to disable. Helpful

    ### Legacy

    # Use the Xinerama extension instead of RandR for multi-monitor support.
    # This setting is provided for compatibility with older nVidia drivers that
    # do not support RandR and using it on systems that support RandR is highly
    # discouraged.

    # By enabling this setting dunst will not be able to detect when a monitor
    # is connected or disconnected which might break follow mode if the screen
    # layout changes.

    ### mouse

    # Defines list of actions for each mouse event
    # Possible values are:
    # * none: Don't do anything.

    #              such action, open the context menu.
    # * open_url: If the notification has exactly one url, open it. If there are multiple
    #             ones, open the context menu.
    # * close_current: Close current notification.
    # * close_all: Close all notifications.
    # * context: Open context menu for the notification.

    # Calculate the dpi to use on a per-monitor basis.
    # If this setting is enabled the Xft.dpi value will be ignored and instead

#
# SCRIPTING
# You can specify a script that gets run when the rule matches by
# setting the "script" option.
# The script will be called as follows:
#   script appname summary body icon urgency
# where urgency can be "LOW", "NORMAL" or "CRITICAL".
#
# NOTE: It might be helpful to run dunst -print in a terminal in order
# to find fitting options for rules.

# Disable the transient hint so that idle_threshold cannot be bypassed from the

#        If the notification is already drawn, it won't get undrawn.

#           withdrawn from screen again and will get delayed like a new notification

When I try to use icons in my scripts, they are not shown.

• notify-send Foo bar -i /usr/share/icons/Papirus-Dark/16x16/actions/activities.svg: Works
  

• notify-send Foo bar -i activities: Does not work (It used to work but broke recently)
  

  This is what dunst logs.

  WARNING: Icon 'activities' not found in themes
  

[bynect]

WARNING: Icon 'activties' not found in themes

This seems like a typo (?)

[UtkarshVerma]

Sure, here it is: https://0x0.st/Kugg.txt

I can confirm that there is a file for that icon as shown by this fzf menu:

[UtkarshVerma]

Something I'd like to add is that Adwaita icons (icon_theme = Adwaita) are being rendered but not Papirus-Dark (icon_theme = Papirus-Dark). The dunst version I am using is 1.13.0.

[UtkarshVerma]

I think I have figured out what was causing the bug. For some reason the icon lookup fails if I have these set (on top of the example dunstrc from the repo):

    # Set icon theme (only used for recursive icon lookup)
    icon_theme = Papirus-Dark

    # Scale small icons up to this size, set to 0 to disable. Helpful
    # for e.g. small files or high-dpi screens. In case of conflict,
    # max_icon_size takes precedence over this.
    min_icon_size = 25

    # Scale larger icons down to this size, set to 0 to disable
    max_icon_size = 25

Should I file a bug report for this?

[bynect]

now that you made me notice this is actually a known problem:
#1116

this would require a rewrite of the icon search I suppose

[fwsmit]

I think it should not require a full rewrite. A partial rewrite is okay.
