print_info: Output Docstring Info.

In openscienceunil/modulr: A Dependency Injection Framework for R

Description

Output the docstring info of a module.

Usage

print_info(name = .Last.name, line_numbers = F, sep = "\n",
  load = TRUE)

info(name = .Last.name, line_numbers = F, sep = "\n", load = TRUE)

Arguments

name	A string (character vector of lenght one). A module name can contain letters, figures and some special characters, namely _, -, and /. The latter is a namespace separator. Names containing /mock/, /mocks/, /test/, /tests/, /example/, or /examples/ have a special meaning related to code testing and examples. The name "modulr" corresponds to a special module and is therefore reserved.
line_numbers	A flag. Should the source line numbers be outputed?
sep	A string (character vector of length one) containing the separator between docstrings blocs.
load	A flag. Should the module be loaded?

Details

A docstring is intended to document a module and provide the user with the ability to inspect it at run time, for instance as an interactive help system, or as metadata. Formally, it is a block of commented lines prefixed with #' and located at the top of the module provider.

The preferred formatting for a docstring is R Markdown, notabely for Modulr Gears (see prepare_gear).

 #' # Info
 #' This is a docstring for `foo`.
