stc is a library and command-line tool for creating, editing, and manipulating transactions for the Stellar blockchain. It supports translating back and forth between human-readable txrep format and Stellar's native binary XDR representation, as well submitting transactions to the network, querying account status, and more. The library makes it easy to build and submit transactions programmatically from go applications.

To install or upgrade this software if you don't plan to hack on it, run the following two commands (assuming your GOPATH is in the default location of ~/go):

rm -rf ~/go/src/github.com/xdrpp/stc
GOPRIVATE='*' go get github.com/xdrpp/stc/...

The rm command is necessary when upgrading because some go get limitation leaves your tree in a detached state, so that go get -u cannot pull from the remote go1 branch. The GOPRIVATE environment variable requests the latest version of the software from github, instead of calling home to Google's module proxy and allowing Google to supply an incorrect or stale version of the software (which unfortunately happened to the author).

Once this command completes, put the ~/go/bin directory on your path and you should be able to run stc.

For most purposes you can simply depend on the latest release. However, if you wish to install the latest development version from within a go module (a directory with a go.mod file), you will need to specify the go1 branch to get autogenerated files that are not available on the master branch. Do so by running:

GOPRIVATE='*' go get github.com/xdrpp/stc/...@go1

See the stc(1) man page for the command-line tool.

See the godoc documentation for the library. Because stc contains auto-generated source files that are not on the master branch in git, you may wish to view the documentation locally, rather than through on-line godoc viewers that may not show you the correct branch. To view godoc, after installing stc with go get as described above, start a local godoc server and open it in your browser as follows:

godoc -index -http localhost:6060 &
xdg-open http://localhost:6060/pkg/github.com/xdrpp/stc

On MacOS computers, run open instead of xdg-open, or just paste the URL into your browser.

Because stc requires autogenerated files, the master branch is not meant to be compiled under $GOPATH, but rather in a standalone directory with make.

Furthermore, to build stc from the master branch, you also need to have the goxdr compiler. Because stc is codeveloped with goxdr, you may want to use a development version of goxdr, which you can do by placing a the goxdr source tree (or a symbolic link to it) in cmd/goxdr. If you don't want to do this, but are okay just using a snapshot of goxdr, you can run:

make depend

Once you have goxdr, you can build stc by running:

make

To install stc, you will also need pandoc to format the man page.
