Stdlib Overview

FScript ships with a built-in standard library and a small set of always-available top-level built-ins.

Everything in this section is available in every script without imports.

Modules

• Console
• Task
• List
• Option
• Map
• String
• Int
• Float
• Bool

Top-level built-ins

• Env
• ignore

Core rules

• Functions are curried.
• Pipe-friendly usage is preferred.
• Task values use the native 'a task type form.
• Task.spawn starts concurrent work and Task.await synchronizes on the result.
• Map keys are always string (map indexer type is fixed to string).
• Many parsing/indexing operations return option instead of throwing.

Built-in types

• type Environment = { ScriptName: string option; Arguments: string list }
• type FsKind = File of string | Directory of string | Missing
