peco (pronounced peh-koh) is based on a python tool, percol. percol was darn useful, but I wanted a tool that was a single binary, and forget about python. peco is written in Go, and therefore you can just grab the binary releases and drop it in your $PATH. peco can be a great tool to filter stuff like logs, process stats, find files, because unlike grep, you can type as you think and look through the current results. Demos speak more than a thousand words! Here's me looking for a process on my mac. You can page through your results, and you can keep changing the query. When you combine tools like zsh, peco, and ghq, you can make managing/moving around your huge dev area a piece of cake! Search results are filtered as you type. When you find that line that you want, press enter, and the resulting line is printed to stdout, which allows you to pipe it to other tools. You can select multiple lines!

By using it, you’ll gain per object and resource types specialized view to e.g. filter out Doctrine internals while dumping a single proxy entity, or get more insight on opened files with stream_get_meta_data. Configurable output formats, HTML or colored command line output. Ability to dump internal references, either soft ones (objects or resources) or hard ones (=& on arrays or objects properties). Repeated occurrences of the same object/array/resource won’t appear again and again anymore. Moreover, you’ll be able to inspect the reference structure of your data. Ability to operate in the context of an output buffering handler.
