integration/fzf-menu not working on MacOS

[hille721]

Hi @akinomyoga,

first thank you for your great work. I have a strange issue: I'm using ble.sh for a while no on my Linux Fedora laptop, where everything works great. Now I applied the same settings on my Mac. First of all, compared to my Linux it is really slow (12ms vs 500ms), but well, I can live with that.
But, the fzf-menu is not working. I only get a empty list. Any tips how can I trouble shoot this problem?

Thanks for the report. I think this must be the same issue as akinomyoga/ble.sh#530. Then I think the call of the column command on the following line should be modified:

blesh-contrib/integration/fzf-menu.bash

Line 45 in 44050ce

formatter=$formatter' | column -ts "$sep" -o "$sep" -c unlimited'

As I explained in akinomyoga/ble.sh#530 (comment), I originally prepared blesh-contrib for example configurations, i.e., the code repository that the external configuration writer can reference. So I chose to provide a simpler setting rather than a perfect and complicated implementation. It is technically possible to implement the feature of column by ourselves, but the shell implementation would be overly complicated (and the speed wouldn't be nice either). However, maybe I finally need to include such a complicated implementation in blesh-contrib.

Maybe I need to add a check for the support for util-linux-2.39 column at least, so it can print an error message if util-linux-2.39 column is not available.

@hille721 I don't have macOS, so I haven't tried, but util-linux seems to be able to be installed in macOS. You may try brew install util-linux and see if it provides column.

@akinomyoga thanks for the fast reply, you pointed me into the right direction, it's working now 👍🏽

It is related to column command. Seems to be MacOS comes with the BSD column, which does not work. So installed the Linux column command via brew install util-linux.

Then I simple changed my .blerc file to:

if [[ "$(uname)" == "Darwin" ]]; then
  # ensure Linux column command is used
  export PATH="/opt/homebrew/opt/util-linux/bin:$PATH"
fi
ble-import -d integration/fzf-menu

Thank you for checking! OK, I'll write about brew install util-linux in the documentation later.
