Gathers all system facts from the host reachable via exec and returns them as a single map. This is the library’s main entry point.

Arguments

• exec - an executor function that runs a script string on the target host and returns {:exit int :out string :err string}. Any transport works: local shell, SSH, containers, etc.

Returns

A map containing:

• :shell - shell detection result from eyre.shell/gather-shell
• :os - OS detection result from eyre.os/gather-os
• :hardware - hardware facts from eyre.hardware/gather-hardware
• :users - user facts from eyre.users/gather-users
• :filesystem - filesystem facts from eyre.filesystem/gather-filesystem
• :network - network facts from eyre.network/gather-network
• :paths - available binary paths from eyre.bins/gather-paths

The shell is detected first; its result is used to select the appropriate embedded collection script for each module. The scripts from all modules are concatenated and executed once, and the parsed output is passed to each module’s processor function.

Example

(require '[babashka.process :as process]
         '[eyre.core :as eyre])

(defn local-exec [script]
  (process/shell {:cmd "bash" :in script
                  :out :string :err :string}))

(eyre/gather local-exec)
;; => {:shell {:type :bash ...} :os {:family :linux ...} ...}
