Installation

gesso can install and run Gesso functions. The functions installed in a Gesso workspace define the capabilities of gesso.

To boostrap gesso for developing applications, run the following commands:

gesso install @gesso/function # Installs the default Gesso function.
gesso install @gesso/new      # Installs the "new" command to create functions.
gesso install @gesso/package  # Installs the "package" command to package applications.

Usage

Interactive (REPL)

Running gesso with no arguments and no piped input runs Gesso in interactive mode. Interactive mode is essentialy a REPL.

Run gesso to open Gesso in interactive mode which presents an input prompt:

$ echo "Hello"
Hello
$ text-to-speech "Hello there"

CLI

gesso and each gesso-function can be run from the command line.

Example: Echo input

gesso echo hello

Example: Generate a UUID

gesso echo uuid-generator

Example: Text to speech (single argument)

gesso text-to-speech "Hello from Gesso."

Example: Text to speech (explicit arguments)

gesso text-to-speech --input.text "Hello from Gesso."

Example: Text to speech (multiple explicit arguments)

gesso text-to-speech --input.text "Hello from Gesso." --input.voice Alex

Example: Text to speech (multiple explicit arguments with simplified syntax)

Input arguments can be specified without the input. prefix when only input arguments are specified.

gesso text-to-speech --text "Hello from Gesso." --voice Alex

Piping input and output

Example: Pipe a command and arguments

echo "echo hello" | gesso

Example: Pipe arguments and specify command as an argument

echo "hello" | gesso echo

Package an application

To deploy, just remove the functions/init, functions/new, functions/edit, and functions/install functions (makes read-only).

Gesso editing functions can be reinstalled by anyone that checks out the project, so they're considered reserved folder names (defined in default gesso.json file).

Deploy

Gesso can run on one or more machines (i.e., a cluster).
