Running command in a directory

[bhargavrpatel]

Hi folks -- Really loving Lino so far. It makes removes string interpolation to run hacky commands. What is the recommended approach in running a command (or a set of commands) in a given directory. Below is an example of set of bash commands I currently run either using system(command) or RubyExpect::Expect.spawn(command)

path = '/somewhere/i/belong`
shell_command = <<-HEREDOC
  (
    cd #{path} && \
    git clean -fdx && \
    git reset --hard && \
    git fetch origin master && \
    git checkout master && \
    git pull --rebase
  )
HEREDOC

RubyExpect::Expect.spawn(command).interact

I am not entirely sure how I should approach this with Lino which allows me to iteratively build essentially the command I would run in bash. How should I run git clean -fdx in a given directory? I am currently doing what is below but I think it takes away from the overall iterative building experience.

Lino::CommandLineBuilder
  .for_command("git")
  .with_subcommand('clean') { |s| s.with_flag('-fdx') }
  .build
  .to_s
# => "cd /somewhere/i/belong && git clean -fdx"

Am I missing something from the DSL I could use? If there is no clean way to do this, it might be helpful to have something along the lines of:

# Hypothetical proposal
Lino::CommandLineBuilder
  .for_command("git")
  .with_subcommand('clean') { |s| s.with_flag('-fdx') }
  .in_directory(repo_dir) # new
  .build
