[Bug] sending remote command on startup doesn't work

[gnuunixchad]

When lf -remote is called on startup, the command doesn't work unless a delay is added, for example:

# lfrc
cmd on-cd &{{
    bash -c '
    source /usr/share/git/completion/git-prompt.sh

    GIT_PS1_SHOWDIRTYSTATE=1
    GIT_PS1_SHOWSTASHSTATE=1
    GIT_PS1_SHOWUNTRACKEDFILES=1
    GIT_PS1_SHOWUPSTREAM=1
    GIT_PS1_STATESEPARATOR=" "
    GIT_PS1_DESCRIBE_STYLE=1
    GIT_PS1_SHOWCOLORHINTS=1

    git=$(__git_ps1 " %s")
    fmt="\033[106m%u@%h\033[00m \033[01;40m%d%f$git\033[0m"
    sleep 0.05
    lf -remote "send $id set promptfmt \"$fmt\""
    notify-send "on-cd" "$fmt"
    '
}}
on-cd

Without the sleep 0.05 it doesn't set the promptfmt if lf is launched in a git directory, while manually cding back and forth does set the prompt correctly.

I have the same issue with on-select:

# lfrc
cmd on-select &{{
    on_select="" # used by ruler.go

    mime=$(file --mime-type -Lb -- "$f")
    case "$mime" in
        audio/*)
            on_select=$(mediainfo --Output="Audio;%BitRate/String% %Duration/String%" "$f")
            ;;
        image/*)
            on_select=$(exiftool -s3 -imagesize -- "$f")
            ;;
        video/*)
            on_select=$(mediainfo --Output="Video;%Width%x%Height% %Duration/String%" "$f")
            ;;
        text/*)
            on_select=$(wc -l "$f" | cut -d' ' -f1)
            ;;
        inode/directory)
            on_select=$(du -hs "$f" | cut -f1)
            ;;
    esac

    sleep 0.1
    if [ -n "$on_select" ]; then
        lf -remote "send $id :set user_on_select \"[$on_select]\""
    else # clear previous value
        lf -remote "send $id :set user_on_select ''"
    fi
}}
on-select

I have to add sleep 0.1 for it to set the UserOptions.on_select on lf's startup.

These variables have been set correctly by that time, but remote commands seem to not have effects. I cannot see anything related from the logs.

Hm, this looks like a valid bug. It seems like the server starts in parallel with the parsing of the config file, so the remote call may come before the server is ready. Not sure how to fix this without changing the entire startup though.

I think the on-init would solve this?

I use it like

cmd on-init &{{
	[ -n "$TMUX" ] && lf -remote "send $id source $XDG_CONFIG_HOME/lf/tmux_lfrc"
}}

Thanks, the issue is gone with on-init, without adding any delay in on-cd:

# commands.conf
cmd on-cd &{{ ... }}
on-cd

# lfrc
cmd on-init &{{
	lf -remote "send $id source $XDG_CONFIG_HOME/lf/commands.conf"
}}

However the issue is related to on-cd and on-select according to the documentation:

This command runs whenever you change the directory but not on startup. You can add an extra call to make it run on startup as well:

cmd on-cd &{{ ... }}
on-cd

cmd on-cd &{{ ... }}
on-cd

lfrc

cmd on-init &{{
lf -remote "send $id source $XDG_CONFIG_HOME/lf/commands.conf"
}}

How about doing this:

cmd on-select &{{ ... }}
cmd on-cd &{{ ... }}

 cmd on-init &{{
	lf -remote "send $id source $XDG_CONFIG_HOME/lf/commands.conf"
	lf -remote "send $id on-select"
	lf -remote "send $id on-cd"
}}

How about doing this:

cmd on-select &{{ ... }}
cmd on-cd &{{ ... }}

cmd on-init &{{
lf -remote "send $id source $XDG_CONFIG_HOME/lf/commands.conf"
lf -remote "send $id on-select"
lf -remote "send $id on-cd"
}}

This works as well, so does just this without sourcing and extra calling:

cmd on-select &{{ ... }}
cmd on-cd &{ ... }}
cmd on-init &{{
    lf -remote "send $id on-select"
    lf -remote "send $id on-cd"
}}
