Configuration

skit config uses git-config grammar: bare skit config lists everything, skit config KEY reads one key, skit config KEY VALUE writes it, --json for machines. Everything lands in config.toml in skit's config directory (skit doctor prints the resolved path; SKIT_CONFIG_DIR overrides it).

Key	Values	Meaning
`lang`	a language tag, or `auto`	UI language
`editor`	a command (arguments allowed)	editor used by `skit edit` and `Ctrl+E`
`form`	`tui` / `plain`	interactive style: inline mini-form, or plain line prompts
`after_run`	`exit` / `stay`	after a menu-launched run finishes: exit skit (default), or return to the menu as a workbench
`shell.bash_path`	a path	Windows: the bash to run shell entries with when none is on `PATH` (validated to exist when set)
`js.runner`	`deno` / `bun` / `node`, empty = auto	force the JS runtime instead of first-found
`mirror`	`on` / `off`	master mirror switch — `off` keeps the saved URLs
`mirror.pypi`	`tsinghua` / `aliyun` / `ustc` / a URL / `off`	Python package index
`mirror.github`	`nju` / an `https://` base URL / `off`	Python builds + the uv binary — https required, since the downloaded binary is executed
`mirror.npm`	`npmmirror` / a URL / `off`	JS/TS package registry

Notes:

The mirror master switch takes only on/off — vendors are chosen per axis. Writing an axis while the master switch is off warns on stderr.
Mirror settings never touch your global uv config or shell; they ride as environment overlays on skit's child processes — see Environment variables.
Prompt runners also live in this file ([[prompt.runners]]), but you manage them through skit runner add / remove / list, not raw keys.
