Advanced Command Line

Here are some advanced command line improvements for gitignore.io

@git2samus

this allows invocations as the previous but also permits passing arguments to curl like: gi --proxy somewhere:8080 -- linux python

function gi() (
    gi_args=()
    for arg; do
        if [[ $arg = -- ]]; then
            curl_args=("${gi_args[@]}")
            gi_args=()
        else
            gi_args+=("$arg")
        fi
    done
    IFS=,
    curl "${curl_args[@]}" https://www.toptal.com/developers/gitignore/api/"${gi_args[*]}"
)

@git2samus

Adds a check to see if curl or wget is installed.

if hash curl; then
    curl "${curl_args[@]}" https://www.toptal.com/developers/gitignore/api/"${gi_args[*]}"
elif hash wget; then
    wget -O- "${curl_args[@]}" https://www.toptal.com/developers/gitignore/api/"${gi_args[*]}"
else
    echo "please install curl or wget to run this command" >&2
    exit 1
fi

@GeorgeErickson

Bash one-liner

function gi { curl https://www.toptal.com/developers/gitignore/api/"$(IFS=, ; echo "$*")"; }

@SantoshSrinivas79

Create a file for the function using vim ~/.config/fish/functions/gi.fish and enter the below code

function gi
  curl -L -s https://www.toptal.com/developers/gitignore/api/$argv;
end

oh-my-zsh

Provides completion for zsh

function gi() { curl -sL https://www.toptal.com/developers/gitignore/api/$@ ;}

_gitignoreio_get_command_list() {
  curl -sL https://www.toptal.com/developers/gitignore/api/list | tr "," "\n"
}

_gitignoreio () {
  compset -P '*,'
  compadd -S '' `_gitignoreio_get_command_list`
}

compdef _gitignoreio gi

@zubin

Provides completion for fish

complete -f -c git -n '__fish_git_using_command ignore' -a '(__fish_print_gitignore_list)'

function __fish_print_gitignore_list
if ! set -q __FISH_PRINT_GITIGNORE_LIST
   set -g __FISH_PRINT_GITIGNORE_LIST (curl -sL https://www.toptal.com/developers/gitignore/api/list)
end
echo $__FISH_PRINT_GITIGNORE_LIST | string split ","
end

@Phoenix09

Improved git alias tee to .gitignore and accept multiple parameters

git config --global alias.ignore \
'!gi() { IFS=","; curl -L -s "https://www.toptal.com/developers/gitignore/api/$*" | tee .gitignore;}; \
gi'
