gofi

This project implements a filesystem tree walker and filter. Similar to unix command "find". Can be used as a library for go projects and has a simple command line.

It was developed mainly to experiment with parallel tree walking and command line interfaces.

Note: This version uses generics so go 1.18 or go tip is required.

Command

The command functionality is very limited and inspired by fd. Use "fd" instead of this project for a fully featured parallel find replacement.

Usage: gofi [options] [search] [path]
  -e, --extension string   search for an extension
  -H, --hidden             do not filter hidden files and directories
      --profile            write cpu profile to cpu.prof
  -r, --regexp             search string is a regexp
  -j, --threads int        number of threads

To search for all files in another directory use an empty search string "". For example:

$ gofi "" /another/directory

To install it you can download the binaries from the latest release: https://github.com/jfontan/gofi/releases/latest

You can also install it with go:

$ go install github.com/jfontan/gofi

Library

Documentation: https://pkg.go.dev/github.com/jfontan/gofi/find

Using default options it returns all the files and directories in the provided path except hidden ones. If Options.Workers is 1 it sequentially reads all directories. If Options.Workers is greater than 0 it parallelizes the work with that amount of goroutines. Options.Workers = 0 means the same number as CPU count.

NOTE: the list of files is not ordered and it can be different in every run.

There are a number of options that can be used to filter the list of files. For example, to return only non hidden files and directories with extension ".go" use:

import "github.com/jfontan/gofi/find"

...

    f := find.New("/path/to/files", find.Options{
        Hidden: false,
        MatchExtension: "go",
    })
    files, _ := f.Find()

You can also specify a callback function that will be executed for all files and directories that match the filters.
