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.
- 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.
- 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.
