AtpClient.Config (AtpClient v0.1.6)

Copy Markdown View Source

Resolves configuration for each backend by merging (in increasing precedence):

  1. Library defaults declared in mix.exs under the :env key.
  2. Application configuration under the :atp_client OTP app.
  3. Per-call options passed as a Keyword.t().

Example

In config/config.exs:

config :atp_client, :starexec,
  base_url: "https://starexec.example.org/starexec",
  username: System.get_env("STAREXEC_USER"),
  password: System.get_env("STAREXEC_PASS")

config :atp_client, :isabelle,
  host: "isabelle.example.org",
  port: 9999,
  password: System.get_env("ISABELLE_PASSWORD"),
  local_dir: "/shared/problems",
  isabelle_dir: "/shared/problems",
  session: "HOL"

Any setting may be overridden per call. For instance,

AtpClient.Isabelle.query(theory, session: "Main")

forces the Main session for that single query regardless of what is set in config.exs.

Summary

Types

backend()

Functions

fetch(backend, key, default, opts \\ [])

Returns the value of key from the resolved settings for backend, falling back to the given default if unset or set to nil.

fetch!(backend, key, opts \\ [])

Returns the value of key from the resolved settings for backend, raising a descriptive ArgumentError if unset or nil.

get(backend, opts \\ [])

Returns the fully resolved settings for the given backend as a keyword list.

Types

backend()

@type backend() :: :sotptp | :starexec | :isabelle

Functions

fetch(backend, key, default, opts \\ [])

@spec fetch(backend(), atom(), any(), keyword()) :: any()

Returns the value of key from the resolved settings for backend, falling back to the given default if unset or set to nil.

fetch!(backend, key, opts \\ [])

@spec fetch!(backend(), atom(), keyword()) :: any()

Returns the value of key from the resolved settings for backend, raising a descriptive ArgumentError if unset or nil.

Use this for settings that have no sensible default (for example :base_url, :password, :local_dir).

get(backend, opts \\ [])

@spec get(
  backend(),
  keyword()
) :: keyword()

Returns the fully resolved settings for the given backend as a keyword list.
