Suggestion when no text

Rendering autocomplete on iterm

bin/hedgehog assumes chruby is installed

Running bin/hedgehog causes:

bin/hedgehog: line 7: /usr/local/share/chruby/chruby.sh: No such file or directory
bin/hedgehog: line 8: chruby: command not found

bin/hedgehog should probably somehow be agnostic to how you install ruby?

chruby support

I think it would make sense to release chruby support either as a separate gem or at least something that can be optionally required in the .hedgehog file.

In the meantime, putting the following straight in .hedgehog should work:

original_cd = function "cd"
function "cd" do |args|
  original_cd.call(args)
  break unless File.exists?(".ruby-version")
  function("chruby").call(Hedgehog::Command::Arguments.new(`cat .ruby-version`.chomp))
end

function "chruby" do |args|
  output = `bash -lc "source /usr/local/share/chruby/chruby.sh; chruby #{args}; echo "§chruby-environment§"; ENV"`
  out, env_str = output.split("§chruby-environment§\n")

  print out

  break unless args.count > 0

  env_vars = env_str.split("\n").map { |env| env.split("=") }

  env_vars.each do |env_var|
    variable, value = env_var
    next unless ["PATH", "RUBY_ROOT", "GEM_HOME", "GEM_ROOT", "GEM_PATH"].include? variable
    ENV[variable] = value
  end
end

ls completion getting irrelevant results

Multiline global variables

Hedgehog > $a = "hello\r\ngoodbye" 
=> "hello\r\ngoodbye"
Hedgehog > echo $a 
 goodbye

Tab completion on first word

when typing bin/\t, should get suggestions on the path

Supporting cd -

cd - should return you to the location you came from.

Not working with "bash-completion" on brew

https://formulae.brew.sh/formula/bash-completion

Buffered input

type sleep 10\necho hello

should execute echo hello after finishing execution of sleep 10

Spawning binary that doesn't exist

What happens

Crashes out of process.

What went wrong

Typed bundle where ruby was set to system ruby, where no bundler was installed.

`cd "/Volumes/Macintosh HD/"` not working as expected

multiline bash commands

awk -v term_cols="${width:-$(tput cols || echo 80)}" 'BEGIN{
    s="/\\";
    for (colnum = 0; colnum<term_cols; colnum++) {
        r = 255-(colnum*255/term_cols);
        g = (colnum*510/term_cols);
        b = (colnum*255/term_cols);
        if (g>255) g = 510-g;
        printf "\033[48;2;%d;%d;%dm", r,g,b;
        printf "\033[38;2;%d;%d;%dm", 255-r,255-g,255-b;
        printf "%s\033[0m", substr(s,colnum%2+1,1);
    }
    printf "\n";
}'

Fish style autosuggestions

It would be amazing to have functionality like the amazing fish-shell's auto suggestions

Supporting $?

e.g. correctly handling

echo "hello" | grep b
echo $?

echo "hello" | grep b
$?
