The Tools application contains a number of stand-alone tools, which are useful when developing Erlang programs.

cover A coverage analysis tool for Erlang. cprof A profiling tool that shows how many times each function is called. Uses a kind of local call trace breakpoints containing counters to achieve very low runtime performance degradation. emacs - (erlang.el and erlang-start.el) This package provides support for the programming language Erlang in Emacs. The package provides an editing mode with lots of bells and whistles, compilation support, and it makes it possible for the user to start Erlang shells that run inside Emacs. eprof A time profiling tool; measure how time is used in Erlang programs. Erlang programs. Predecessor of fprof (see below). fprof Another Erlang profiler; measure how time is used in your Erlang programs. Uses trace to file to minimize runtime performance impact, and displays time for calling and called functions. instrument Utility functions for obtaining and analysing resource usage in an instrumented Erlang runtime system. lcnt A lock profiling tool for the Erlang runtime system. make A make utility for Erlang similar to UNIX make. tags A tool for generating Emacs TAGS files from Erlang source files. xref A cross reference tool. Can be used to check dependencies between functions, modules, applications and releases.
