Module setup 

Interactive setup wizard for krypt setup.

Reads [prompts.<name>] sections from .krypt.toml, asks the user questions via Prompter, and writes the collected values to destination files using one of four built-in writers:

• gitconfig — merges key=value pairs into a git-style ini file.
• hypr_vars — patches $VAR = value lines in a Hyprland config.
• env — writes export K=V lines to a shell env file.
• generic_template — substitutes {{key}} placeholders in a template.

Default resolution order (first hit wins)

1. read_var = "X" — read $X = <value> from the destination file.
2. default_from prefix:
   • git:<key> — shell out to git config --get <key>. We deliberately keep this one shell-out because git-level user config (name, email, signing key) lives inside git’s own config system and cannot be read any other way without reimplementing the full git config search order. gix is only used for repo operations in update; it is not used here.
   • env:<VAR> — read env var.
   • field:<key> — value of an earlier field in this same run.
   • read_var:<X> — same as read_var shorthand.
3. default = <toml value>.
4. No default.

Structs

FakeGitConfig

Fake git config for tests.

RealGitConfig

Shells out to the system git binary.

RealPrompter

Dialoguer-backed prompter used in production.

ScriptedPrompter

Pre-canned answers for unit tests. Pops answers in FIFO order.

SetupOpts

Inputs to setup.

SetupReport

Summary of a setup run.

YesPrompter

Returns each field’s computed default without prompting. Errors if a required field has no default.

Enums

ResolveError

Errors from the default resolver.

SetupError

Errors from setup.

Traits

GitConfig

Abstraction over git config --get <key> so tests can avoid a real git binary.

Prompter

Abstraction over interactive prompts so tests can inject scripted answers.

Functions

setup

Run the interactive setup wizard.

setup_with_destinations

Run setup with per-section destination paths and optional template sources.

setup_with_destinations_and_srcs

Full entry point with both destination and source paths.

write_generic_template

Substitute {{key}} placeholders in a template file and write to dst. Missing keys leave the placeholder intact.
