go_cwd_logger

go_cwd_logger

Rewrite of cwd_logger in Go

A simple MongoDB backed working directory logging system to provide quick access to frequent or recent directories for a unix type system.

Usage

The basic usage is to call cwd_logger when changing directory (chpwd_functions in zsh is a good spot for this). Calling it as cwd_recently will print out the 20 most recent directories, runnnig it as cwd_frequency the 20 most frequent.

For either, passing a numeric argument will then print that directory. Any argument other than a number will be treated as a regular expression for a search on all the paths logged, returning the first match

user@host:/some/working/dir$ cwd_logger
user@host:/some/working/dir$ cd .
user@host:/some/working/dir$ cwd_recently
usage: cwd_recently index
 0 - /some/working/dir
user@host:/some/working/dir$ cd /some/other/dir && cwd_logger && cwd_frequency
usage: cwd_frequency index
 0 - /some/other/dir
 1 - /some/working/dir
user@host:/some/other/dir$ cd "$(cwd_frequency 1)"
user@host:/some/working/dir$ cwd_frequency
usage: cwd_frequence target_index|path regex
 0 - /some/working/dir
 1 - /some/other/dir
user@host:/some/working/dir$ cd "$(cwd_frequence other)"
user@host:/some/other/dir$

Easiest usage comes from using some shell functions & aliases to these commands, see cd_functions.zsh for examples for zsh

Installation/Build/Setup

Dependencies

• MongoDB
• Go
• mgo driver (which has some dependencies of its own)

Install

The standard go get, go build type of setup

go get github.com/glennsb/go_cwd_logger
go build github.com/glennsb/go_cwd_logger

You should end up with a $GOPATH/bin/go_cwd_logger, put that in your $PATH as well as symlinks to it named as cwd_recently & cwd_frequency

By default it will connect to a MongoDB server as mongodb://localhost/USERNAME

You can override this by setting a CWD_LOGGER_URI environment (or editing the source)

It will use a collection named logged_dirs in the given database

Why

I liked the old cwd_logger, but was tired of Ruby's gem dependency issues. I also wanted to play with Go more this morning
