# We just place everything while in home directory
cd

## =========== fzf
git clone --depth 1 https://github.com/junegunn/fzf.git ~/.fzf
echo '# Source fzf' >> $HOME/.bashrc
# Note that fzf has an interactive option during installation to add to the bashrc already
~/.fzf/install
echo '' >> $HOME/.bashrc

## =========== zoxide
curl -sSfL https://raw.githubusercontent.com/ajeetdsouza/zoxide/main/install.sh | sh
echo '# Start zoxide' >> $HOME/.bashrc

echo '# Add cmake to PATH' >> $HOME/.bashrc
echo 'export PATH=$HOME/cmake-3.31.4-linux-x86_64/bin:$PATH' >> $HOME/.bashrc
echo '' >> $HOME/.bashrc

# Add some common commands I use

# You can use this like `qcmake -G Ninja` to append to the cmake command
echo '' >> $HOME/.bashrc
echo 'qcmake() {
  cmake -B build $*
  cd build
}' >> $HOME/.bashrc
echo 'rcmake() {
  rm -rf build
}' >> $HOME/.bashrc
echo '' >> $HOME/.bashrc

## =========== Neovim: Get latest neovim? There's a curl-way to parse the API but i'm just going to update this version myself manually..

## =========== Install a newer version of git in case you don't have admin rights
# NOTE: this is a stub. we may also need to install openssl and then curl before this, otherwise
# git won't really work properly
# Here's what I found so far:
# 1. zlib
# 2. openssl
# 3. libpsl
# 4. curl (uses above 2)

## ========== add some other aliases (NOTE: this section is to be copied to your bashrc manually)
# This lets you export an envvar to be the current dir
