Slick Call Stacks

Project Status: Active - The project has reached a stable, usable state and is being actively developed. Linux Build Status Windows Build status CRAN RStudio mirror downloads Coverage Status

Better looking call stacks after an error.

Installation

source("https://install-github.me/mangothecat/tracer")

Usage

library(tracer)

After an error, call tb() instead of traceback(), to get a nice error stack summary:

To browse the code at the locations of the calls, supply the number of the call to tb():

Note that tracer can often show the (deparsed) source code of the call location, even if the original R source code is no more available, like in the case of installed packages.

Caveat

tracer sets the error handler via options(error = ...). If the user changes the error handler manually, then tracer will not work.
