Insufficient documentation / how to run it?

[stepanselyuk]

Hello,

I've downloaded the latest release archive and there are the binary file and shell files. I created ~/.bin directory and placed the files there and added ~/.bin to the PATH.

I'm on Ubuntu 20.04.2 and use Guake + Zsh + OhMyZSH (with plugins) + powerlevel10k theme. What are my next steps? I placed at the end of .zshrc:

export PATH="$PATH:$HOME/.bin"
export MCFLY_FUZZY=true
export MCFLY_RESULTS=50

# tried with it and without it
# ~/.bin/mcfly.zsh

eval "$(mcfly init zsh)"

Once I got setup-dialog from McFly and it even created ~/.mcfly/history.db, but then it's not bonded with Ctrl+R. I tried to disabled fzf and history plugins from OhMyZSH, and after that, I've got just plain ctrl+R function.

How to make it work and how to use mcfly.zsh / mcfly.bash scripts?

[stepanselyuk]

Ok so mcfly init zsh just returns the same content as in these scripts...

I tried to run

eval "$(mcfly init zsh)"

in opened shell and it worked. But for some reason, it's not working when I placed that at the end of the .zshrc file.

Are you sure that last line of your .zshrc file is getting executed? Maybe add an echo statement or check that MCFLY_HISTORY is set in env?

I did a little debugging and seems my ZSH installation reacts to this instruction:

[[ -t 0 ]] || return

when I changed it to:

if [ -t 1 ]; then return 0; fi

it started working as expected...

[cantino]

Does if [[ ! -t 0 ]]; then return 0; fi work?

[stepanselyuk]

Nope, that is not working...

Good examples of how to check if a shell is interactive or not in various shells: https://unix.stackexchange.com/questions/26676/how-to-check-if-a-shell-is-login-interactive-batch/26782

[stepanselyuk]

[[ ! -o interactive ]] && return 0

this works for me

Should be fixed in https://github.com/cantino/mcfly/pull/164

[thomaseizinger]

Should be fixed in #164

Can confirm that this fixes the issue for me!

Great, thanks for checking @thomaseizinger!
