Slang is a visual flow-based programming language and programming system. It consists of the YAML-based Slang exchange format, the Slang daemon and the Slang UI.
Slang daemon is the service which serves the user web interface (Slang UI) and runs all your operators. You don't need anything else to start working with Slang, so this here is the place to start.
If you want to run Slang, you can simply download the latest release, unpack and run it. We have binaries for Windows, Linux and MacOS.
If you rather want to compile it yourself, you first need to install Go.
After you have set up Go and cloned the repository, switch to the root directory and run
go build ./...
This will fetch all the dependencies. After that, run
go build -o slangd ./cmd/slangd (on Windows: go build -o slangd.exe ./cmd/slangd)
Alternatly you just can run the daemon without compiling
go run ./cmd/slangd
That's it! Now you just need to run slangd (on Windows: slangd.exe) and Slang will take care of the rest such as downloading the UI and standard library.
If you want to edit stdlib, just run
SLANG_LIB=/tmp/ SLANG_DIR=<path-to-slang-lib>/slang go run ./cmd/slangd --only-daemon
Slang runner allows you to run a blueprint via cli. Input data must be passed through STDIN. Output will be written to STDOUT. Input and output data must be valid newline-delimited json (ndjson). As an argument you have to provide a slang file.
