if you need to inject a message into a wall of text printed to the screen, like when starting jekyll or astro or rails server, you can read lines and print it at the appropriate time.
#!/bin/bash
pnpm run dev | while read line
do
echo "$line"
if [[ "$line" == *"Local"* ]]; then
echo "✅ Your site is live! 🎉"
fi
done
Interesting links from week 3 of 2024.
Here are some interesting things I’ve found this week. I’m just getting started with this, so it may be a slow ramp up.
Elixir
TIL
Running mix ecto.dump
creates a structure.sql file in ./priv/repo.
This is easy to forget to keep updated, so one easy way is to add this in the aliases()
function in mix.exs:
"db.migrate": ["ecto.migrate", "ecto.dump"]
"db.rollback": ["ecto.rollback", "ecto.dump"]
I keep forgetting how to change the remote for a git repo.
1) View existing remotes
git remote -v
2) Change the ‘origin’ remote’s URL
git remote set-url origin https://github.com/user/repo2.github
3) Verify new remote URL
git remote -v
How to get a random number in Elixir.
iex(1)> :rand.uniform(6)
iex(2)> Enum.random(1..6)
Sometimes you need a unique integer, and of course Elixir has you covered. This is very useful for Factories if you want to implement something like sequences to avoid errors due to database unique constraints.
iex(1)> System.unique_integer(~w[monotonic positive]a)
1
iex(2)> System.unique_integer(~w[monotonic positive]a)
2
iex(3)> System.unique_integer(~w[monotonic positive]a)

Another css example I want to hang on to.
It’s pushable!
Code:
<button
class="mb-4 p-2 w-32 transition ease-in-out duration-100 outline outline-1 shadow-[0_5px_0px_0px_rgba(0,0,0,0.6)] active:shadow-none active:translate-y-1 "
>
pushable button
</button>
There’s a lot of more examples at Josh Comeau’s site and hnldesign
