As dev, I want create_dependencies_file() to use sub-functions to create the output to be used in dockerfiler::add_dockerfile()

[MurielleDelmotte]

create_dependencies_file() uses DESCRIPTION as source of information. _Note that DESCRIPTION file can be auto-fill using find_remotes()

Criteria of success

• [x] A dependencies_file_text() exists and is tested

• [x] It is used in create_dependencies_file()

• [x] create_dependencies_file() returns a list with the contents of dependencies_file_text() to be reused elsewhere

Technicals

• [ ] I'd like to have a subfunction that would help create the output as follows to be used in golem::add_dockerfile()

⚠️ fonction plus trop utilisée et qui utilisait : dockerfiler::doc_from_desc()

# Remotes ----
install.packages("remotes")
remotes::install_github('local::mylocalpackage')
remotes::install_cran('cli')
remotes::install_cran('config')
...

• [ ] I'd like to have a subfunction that would help create this other output as follows to be used in dockerfiler::add_dockerfile()

  # Remotes ----
  install.packages("remotes")
  remotes::install_github('local::mylocalpackage')
  remotes::install_version('cli', version = "0.1.0")
  remotes::install_version('config', version = "2.1.2")
  ...

• I think that listing all packages with their version with install_version() is not reliable, because of versions of sub-dependencies. I would recommend to redirect users to {renv} and create the Dockerfile using {renv}.

• It would be interesting to create the "socle" part of {dockerfiler} that install all deps, even without {renv}

Perfect !
