Dynamic 'R' Prompt

Set the 'R' prompt dynamically, from a function. The package contains some examples to include various useful dynamic information in the prompt: the status of the last command (success or failure); the amount of memory allocated by the current 'R' process; the name of the R package(s) loaded by 'pkgload' and/or 'devtools'; various 'git' information: the name of the active branch, whether it is dirty, if it needs pushes pulls. You can also create your own prompt if you don't like the predefined examples.

Dynamic R Prompt

Set the R prompt dynamically, from a function. The package contains some examples.

Examples

This is prompt_fancy() and it has

• The status of the last command (success or failure).
• The amount of memory allocated by the current R process.
• The name of the R package being developed using devtools.
• Name of the active git branch.
• State of the git working tree (needs pushes, pulls, and/or dirty).

A powerline clone, that also shows the system load average and the current working directory.

Installation

Install the package from CRAN, as usual:

install.packages("prompt")

Usage

Use one of the pre-defined prompts, as on the screenshots, or create your own. You can set the prompt in your .Rprofile. Maybe you only want to do this in interactive mode:

if (interactive()) prompt::set_prompt(prompt::prompt_fancy)

or the powerline prompt:

if (interactive()) prompt::set_prompt(prompt::new_prompt_powerline())
