feat: export information as env vars to children commands (preview and interactive) - #1200
Commands run at startup, through previews, execute, execute-silent, and reloads can access interface state through matching SKIM_* and FZF_* environment variables. Values include query, selection, position, layout, and action details when applicable. Reload commands receive a snapshot of the state when triggered. Inapplicable or oversized values are omitted, and stale inherited values are removed.
Added fzf-style names for keyboard events.
Documentation
Documented available child-process environment variables, when values are available, and how to use them in a preview-command example.
No actionable comments were generated in the recent review.
Walkthrough
Skim exports TUI state under SKIM_ and FZF_ prefixes for preview, execute, execute-silent, and reload commands. The change adds key-name formatting and updates development-shell toolchain setup.
Changes: Child-process environment
Layer / File(s)
Summary
State snapshots and exported values src/tui/app.rs, src/tui/app_tests.rs, README.md, ARCHITECTURE.md, src/manpage.rs
App records action, key, and terminal-area state. It exports applicable values under both prefixes and identifies omitted values for removal. Tests and documentation describe exported values, conditions, and snapshot timing.
Preview, execute, and execute-silent paths apply environment assignments and remove listed inherited variables. Tests cover environment propagation through these commands.
Reload events capture environment state before clearing items. Reader passes the snapshot to reload commands. Tests cover initial-command and reload snapshots.
Entering the development shell can print rustup errors when the toolchains cannot be installed. This is minor, and the runtime feature changes show no remaining concrete blocking defect.

Explanation
The title follows the conventional commits prefix "feat:" and states the main change: exporting information as environment variables to child commands for preview and interactive (execute, reload) use. The changeset adds SKIM_ and FZF_ prefixed environment snapshots for preview, execute, execute-silent, and reload commands, which matches the title. The title is 83 characters, slightly long, but it remains descriptive and specific.
Full details: Test Coverage
Explanation
The PR adds a feature, child-process environment exports for preview, execute, execute-silent, and reload. The feature has unit and integration tests, and most new branches run under test. Unit tests: - src/binds_tests.rs: key_name_formats_fzf_style covers canonical names, alias inputs, shift on non-character keys, BackTab with all modifiers, and synthetic event names. - src/tui/util_tests.rs: apply_child_env_unsets_then_sets covers the unset-then-set order. - src/tui/app_tests.rs (about 440 added lines) covers: - core exports under both prefixes; - omission of inapplicable variables (CURRENT_ITEM, NTH, WITH_NTH, WRAP, PREVIEW_*); - WRAP, INPUT_STATE disabled, and DIRECTION down under TuiLayout::Reverse; - ACTION and KEY tracking, including follow-up actions; - selected-item newline joining, ANSI stripping, and the NUL and 64 KiB omission branches; - the oversized SELECTED_ITEMS case; - reload capture and queued reload order; - SetCmd; - execute and execute-silent snapshots; - all three command-preview variants. - src/tui/preview_tests.rs: plain-preview env inheritance and PTY env apply with removal of HOME and SKIM_QUERY. - src/helper/item_reader_tests.rs: invoke_exports_child_env. Integration and behavioral tests: - src/skim_tests.rs: initial-command startup state and the reload-before-clear ordering (alpha|alpha||reload). - tests/execute.rs: execute_child_inherits_skim_env. - tests/preview.rs: preview_env_vars snapshot test, with snapshot files added. Minor gaps, which do not fail the check: - key_name fallback other => format!("{other:?}") branch and the shift-on-non-alphabetic-character branch do not appear directly in the added tests. - Reload(None) and the preview_fn preview branch have no visible dedicated test. - Preview::spawn PTY path with unset is covered. The non-PTY apply_child_env path is covered by a plain-preview test. The README, ARCHITECTURE, manpage, and flake changes are documentation or build-environment changes. The manpage has a test that checks the new subsection.

hook to handle each failed install explicitly, so failure does not interrupt
interactive `nix develop` entry. Keep `--no-update` and `--no-self-update` on
both the default and nightly toolchain installs.

- Line 369: Update key_name’s handling of KeyCode::BackTab to normalize
Crossterm’s all-modifiers-set representation to shift-tab before formatting
modifiers, so SKIM_KEY and FZF_KEY report the key the user pressed.
Review comments at @src/skim.rs:
- Line 240: Update start() to pass an App::child_env() snapshot to start_reader
instead of an empty environment, so the initial command receives configured
state variables just like subsequent reloads.
- Line 284: Update handle_reload to capture the child environment snapshot
before clearing item_pool or item_list, then use that snapshot when launching
the reload command so CURRENT_ITEM, SELECTED_ITEMS, and their counts reflect the
state that triggered the reload.
Review comments at @src/tui/app.rs:
- Around line 1596-1600: Update the environment snapshot handling that pushes
SKIM_ and FZF_ variables so each spawn path first removes inherited state
variables omitted from the snapshot, then applies the snapshot; cover absent and
oversized values while preserving included values.
- Line 870: Update the action-dispatch flow that assigns self.last_action from
act.name() so every non-suppressed dispatched action refreshes the action
context, including actions dispatched through execute-silent and conditional
chains. Capture that context when queuing deferred execute and preview events so
later actions cannot overwrite the value those events use; leave separately
emitted action events unchanged.
- Around line 1535-1541: Update the SELECTED_ITEMS construction in child_env to
stop accumulating once the candidate value exceeds MAX_ENV_VALUE_BYTES, and omit
the variable when it exceeds that limit; avoid stripping or joining the
remaining selected items.

Capture the reload environment before clearing selection or deferring execution.
Both reload branches clear selection before Skim::handle_reload captures the environment in src/skim.rs, Line 277 through Line 296. A reload triggered with selected items therefore receives SELECT_COUNT=0 and empty SELECTED_ITEMS.
Deferred handling also permits later actions to replace the trigger state. For example, if-query-empty(reload(true)+set-query(changed)) changes the query before the reload snapshot is captured.
Capture the environment before clear_selection(). Carry that snapshot with the reload event, as part of the same operation as command expansion.

Major · Functional Correctness · Quick win
Keep the preview test independent of the optional cli feature.
Cargo.toml enables shlex only through cli and does not declare it as a development dependency. This Unix test also compiles without cli, so cargo test --no-default-features --lib fails to resolve shlex. Add shlex as a development dependency, or use an always-enabled quoting helper. Apply the same correction to the existing silent-execute test. (raw.githubusercontent.com)
