Leaps is a service for collaboratively editing your local files over a web UI, using operational transforms to ensure zero-collision synchronization across any number of editing clients.

Simply navigate to a directory you want to share, run leaps, open the hosted page in your browser and direct any friends on your LAN to the same page. You can now collectively edit any documents in that directory.

Leaps can also be used as a library, with implementations of accessors for various document hosting solutions and plugable authentication layers, allowing you to build your own services to suit many service architectures.

Leaps server components are implemented in Golang, and has a client implemented in JavaScript that can currently be used with ACE, CodeMirror and Textarea editors.

To read more about the service library components and find examples check out the godocs.

To read about the JavaScript client check out the README.

Install

Leaps is a single binary, with no runtime dependencies. Just download a package for your OS from the latest releases page.

From homebrew

brew install leaps
leaps -h

Build with Go

go get github.com/jeffail/leaps/cmd/...
leaps -h

Vendoring

Versions of go above 1.6 should automatically go get all vendored libraries. Otherwise, while cloning use --recursive:

git clone https://github.com/jeffail/leaps --recursive

Or, if the repo is already cloned, get the latest libraries with:

git submodule update --init

To add new libraries simply run:

PACKAGE=github.com/jeffail/util
git submodule add https://$PACKAGE vendor/$PACKAGE"

It might be handy to set yourself a function for this in your .bashrc:

function go-add-vendor {
    git submodule add https://$1 vendor/$1
}
