Installing flow on your system

There are three main options to getting a working install of flow on your system:

From Source

All pretty standard:

clone this repo (git clone https://github.com/andrewdavidmackenzie/flow)
install pre-requisites by running make config
build and test by running make

That will leave binaries (such as flowc and flowrcli etc) in target/debug, and flowstdlib installed into $HOME/.flow/lib.

You can run the binaries from the target folder (make sure it is in your $PATH) or you can install using

cargo install.

From latest GitHub release download and manually install the executables for your target system:

Then download the portable WASM flowstdlib and expand to the directory $HOME/.flow/lib/flowstdlib

Install the latest release using the following install script from the source repo:

curl --proto '=https' --tlsv1.2 -sSf https://raw.githubusercontent.com/andrewdavidmackenzie/flow/master/install.sh | sh

That will:

install the portable flowstdlib WASM library into $HOME/.flow/lib
install the context definition of flowrcli flow runner into $HOME/.flow/runner
install the context definition of flowrgui flow runner into $HOME/.flow/runner

and leave things ready for running.

You can test your install works by running an example flow directly from the web, without cloning the repo to get the examples:

flowc -r flowrcli https://raw.githubusercontent.com/andrewdavidmackenzie/flow/master/flowr/examples/fibonacci/root.toml

Which should download and run the fibonacci series example, which will produce a stream of numbers on standard output.
