mcfly not starting

[mtekp]

While mcfly said to wait for 2 minutes, I did wait but seemed it had stuck so I opened another terminal window, I got some error like db locked or something. Then onwards I just see errors, for any command.

Try removing ~/.mcfly/ and letting to process finish. How big is your bash / zsh history file?

[mtekp]

well this worked. My zsh history was 165k. Also the historydb generated is 598k. Is this normal? And after enabling mcfly, I dont see the ctrl-r prompt be like what it is shown in readme.

[mtekp]

I meant not like this git search

[cantino]

What do you see, if not that prompt?

[mtekp]

❯ head ~/.zshrc   
# If you come from bash you might have to change your $PATH.
# export PATH=$HOME/bin:/usr/local/bin:$PATH
source /usr/share/zsh/share/antigen.zsh

if [[ -r ~/.config/mcfly/mcfly.zsh ]]; then
      source ~/.config/mcfly/mcfly.zsh
fi

# Path to your oh-my-zsh installation.
export ZSH="/home/manjunath/.oh-my-zsh"

❯ head  ~/.config/mcfly/mcfly.zsh 
#!/bin/zsh

# Ensure stdin is a tty
[[ -t 0 ]] || return

# Avoid loading this file more than once
if [[ "$__MCFLY_LOADED" == "loaded" ]]; then
  return 0
fi
__MCFLY_LOADED="loaded"

left side is mcfly enabled and right is zsh-peco-history enabled

[cantino]

I don't think ~/.config/mcfly/mcfly.zsh is getting sourced. Do you see various MCFLY_ variables set in env?

[mtekp]

❯ echo $MCFLY_
MCFLY_HISTORY     MCFLY_PATH        MCFLY_SESSION_ID

~ via ☕ v11.0.6 
❯ echo $MCFLY_HISTORY 
/tmp/mcfly.Uv1mmSdg
~ via ☕ v11.0.6 
❯ echo $MCFLY_PATH 
/home/manjunath/.cargo/bin/mcfly
~ via ☕ v11.0.6 
❯ echo $MCFLY_SESSION_ID

I had sourced something else again later in .zshrc which was causing the problem. Works perfectly fine and great tool I love Rust and love this tool too
