Show me your .gitignore

Every time I start a new project I just download a .gitignore from Github/gitignore

Recently I found out there's a VSCode extension which does that for me.

When I start a project, I go to this site to create .gitignore.

Since I'm using JetBrains's IntellIJ IDEA most the time, my .gitignore is normally just:

.idea/
*.iml

This makes sure I'm not committing any IDE generated files on my Java/Kotlin projects.

For those who might not be familiar with the *.iml, it tells Git to ignore any files names that end on .iml. This can be done to any kind of files too.

.DS_Store
lib-cov
*.seed
*.log
*.csv
*.dat
*.out
*.pid
node_modules
.directory
[._]*.s[a-w][a-z]
[._]s[a-w][a-z]
Session.vim
play.js
coverage
out
.nyc_output
docs/_site
docs/.sass-cache
.vscode

The first 2/3 or more dates from before I took over the project, so now I'm curious what those regexes are doing...

Mine's pretty simple, for my apps.nektro.net project this is it

/node_modules/
/bin/

Can I do a promote a tool here for those who like building random projects?

npmjs.com/package/gitignorer

It is a tool that allow you to init gitignore file easily given a default profile.

Gitignore for my $HOME directory (inverse of the usual, ignore everything except some files) and a typical project (with a bunch of project specific files)

I like to have two .gitignore, one for me (a global one), and one for the project that I'm working on.

In my global gitignore, named .gitexcludes(github.com/diegoholiveira/dotfiles...), I ignore files that are generated by my own environment, like IDEs files, vagrant files and others.

In my projects, my .gitignore only have entries that are directly about the project: like build files, pyc files and vendor folder, generated files and other.

This helps me to keep things very organized.

My Rails 5 app:

# Ignore bundler config.
/.bundle

# Ignore all logfiles and tempfiles.
/log/*
/tmp/*
!/log/.keep
!/tmp/.keep

# Ignore Byebug command history file.
.byebug_history

# Ignore environment file
.env

# Ignore locally compiled assets and local media
/public/assets/*
/public/media/*
/node_modules/

# Ignore Redis writes to disk
/dump.rdb

# Ignore Docker config
/docker-compose.yml
/Dockerfile

# Ignore local Webpack files
/public/packs
/public/packs-test
/node_modules

# Ignore master key for decrypting credentials and more.
/config/master.key

From a gem that I made via a plugin generator:

.bundle/
log/*.log
pkg/
test/dummy/db/*.sqlite3
test/dummy/db/*.sqlite3-journal
test/dummy/log/*.log
