node-tick-processor

easy-to-install processor for the v8 profiler log

This is little more than a repackaging of the "tick processor" that ships with the v8 source code.

Installation

$ npm install -g node-tick-processor

Usage

• Run your script with profiling enabled, to generate the v8.log file
  • $ node --prof myscript.js
• In the same directory, run this script
  • $ node-tick-processor

For help, add the --help flag.

Contributing

• checkout your own copy of the source (or make a fork first)
• edit header.js as desired
• run ./rebuild.sh
• submit changes in a github issue (or pull request)

node-tick-processor's Issues

works with different versions of node

The current build system creates a node-tick-processor for the latest version of v8. However that might not be the version (built into node) that generated the log file.

OSX: nm usage error

Getting this error a lot when running on OSX 10.9.5:

Usage: /Applications/Xcode6-Beta5.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/nm [-agnopruUmxjlfAP[s segname sectname] [-] [-t format] [[-arch <arch_flag>] ...] [file ...]

The program still ends up working though.

Expecting v8.log filename?

I've tried running this with logs generated by node 4.2, which are named eg. isolate-0000000000123A30-v8.log. However, this package seems to expect v8.log. Perhaps there's a way to specify a different filename, but the --help switch is not working for me.

I suspect something went wrong when publishing it?
