Share an Elixir or dev-env tip a day

I accidentally pasted my banking password into Terminal, so wanted to delete it to be on the safe side!

# close the app, then: 
rm ~/.zsh_history
rm -rf ~/.zsh_sessions

Why not edit the file to remove that line?

I use my shell history constantly, so I’m loathed to blow it away

That’s actually a good idea!

(I wasn’t too bothered on this machine though as I’ve just done a clean install, so there was very little history)

(edit: actually the top tips are all things like “new elixir version released (in 2017)!”…)

export ERL_AFLAGS='-kernel shell_history enabled  -kernel shell_history_path \".erl.history\"'

The above makes iex sessions to store their history on a per-project basis in project directories. ,gitignore should be also updated to include /.erl.history/.

I have already said it few times in different places, but do yourself a favour, and if you are using Git, then have globally (in ~/.config/git/attributes) or per project (in .gitattributes):

mix.lock merge=binary

This will make conflict resolution of mix.lock much easier.

Explanation

This will tell Git to treat Mix lock file as a binary file when doing merges/rebases. This mean, that if there is a conflict, there will be stop (so you need to resolve such conflict), but it will leave file as is (with no conflict markers). This makes my life much easier, as you can then just do mix deps.update --all (as it is most of the time source of such conflicts) and then just git add mix.lock && git rebase --continue.

Talking about git, I like to configure mine based article: How Core Git Developers Configure Git | Butler's Log. It contains some good info and recommendations you can use to improve the git defaults in your dev env.

Thanks for sharing, that was a good read.

This thread is similar in spirit to a thread I made a while back, so I’ll share it here: What took you way too long to figure out?

I was going to put something in there the other day, but never got around to it… and now I forget what it was . I remember enough to know it would have fit perfectly here…

Also just wanted to bump the thread.

Added a link to it in the first post

This thread may also be of interest: What took you way too long to figure out?

Kinda off-topic tip… but keep a note book handy/by your bed. Writing things down that come in to your mind just before going to sleep can actually help you sleep - as you’re not worrying about having to remember them!
