Stellar transaction compiler
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.
Installing stc
for non-developers
To install or upgrade this software if you don't plan to hack on it, run the following:
GOPROXY=direct go install github.com/xdrpp/stc/...@latest
The GOPROXY
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:
rm -rf ~/go/src/github.com/xdrpp/stc
GOPROXY=direct go get github.com/xdrpp/stc/...@go1
Assuming your GOPATH is in the default location of ~/go
, 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.
Using stc
See the stc(1) man page for the command-line tool. There's also a video of a presentation and demo of stc at the 2020 Stellar Meridian conference.
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.
Building stc
for developers
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.
Building stc
for experimental protocol versions
To build a version of stc
supporting changes to the transaction
format that have not yet been merged into stellar-core
, you can
fetch alternate XDR files with either of the commands:
./make-xdr
BRANCH
./make-xdr
REPO BRANCH
Here REPO is the git repository from which to pull the non-standard
version of stellar-core
(default
https://github.com/stellar/stellar-core.git), and BRANCH is either
a branch name in the remote repository or a github pull request
number. To revert to the standard XDR, simply run ./make-xdr
with
no arguments.
