+ cache_file=/home/schuster/.cache/clipmenu.6.user/line_cache
+ [[ '' == --help ]]
+ [[ '' == -h ]]
+ launcher_args=(-l "${CM_HISTLENGTH}")
+ [[ dmenu == fzf ]]
+ [[ dmenu == rofi ]]
+ [[ dmenu == rofi-script ]]
++ list_clips

Hey,

With respect, you're filing a lot of issues but not really providing a lot of information :-) Last time around, I asked you to tell me which lines are slow when launching under bash -x. Could you please do that?

[kristoferus75]

Hi !

if i start this command i see all lines immediately

• : dmenu
• : /home/user/.cache
• : 8
• major_version=6
• shopt -s nullglob
• cache_dir=/home/user/.cache/clipmenu.6.user
• cache_file=/home/user/.cache/clipmenu.6.user/line_cache
• [[ '' == --help ]]
• [[ '' == -h ]]
• launcher_args=(-l "${CM_HISTLENGTH}")
• [[ dmenu == fzf ]]
• [[ dmenu == rofi ]]
• [[ dmenu == rofi-script ]] ++ list_clips ++ dmenu -l 8 ++ LC_ALL=C ++ sort -rnk 1 ++ cut '-d ' -f2- ++ awk '!seen[$0]++'

and also i see dmenu immediately but cpu usage is very high and it is slow if i scroll in dmenu

the problem is since i copy lines from libreoffice table like this:

xxxxxxxxxxxxx 20.20.20.20 192.168.29 /24 xxxxx-8P 10.9.68 10.91.68 10.92.68 10.191.68 10.192.68 10.193.68 10.99.68 172.23.68 172.24.68 172.33.68 172.34.68

Realistically, if dmenu is slow, you're going to have to talk to dmenu developers. We already apply restrictions to max clips and max length.

Sorry i use dmenu for also other functions -> and have no problems -> but ok i can try rofi also with clipmenu -> i will see and give info !

[kristoferus75]

intressting with rofi :

if i copy one line in libreoffice table -> i see now this line 10 Times in rofi (ok this happen because i mark slowly word by word or column by column -> in dmenu i have not this behavior -> is it possible to change this ?

if i copy only one word i see only one word -> ok

it seems you have right -> with rofi there is no delay and also no high cpu ussage hmmmmm

i try now also an other version of dmenu -> i give info !

Thanks !

[kristoferus75]

ok same problem with:

dmenu 4.8 dmenu 4.9 dmenu 5.0

also without patches

with rofi -> only the problem with 10 lines if i copy a table word by word or column by column
