@gustav-fff you need to make sure that it is getting compiled everywhere and mark |
dmtrKovalenko
changed the title

@gustav-fff also make it configurable for neovim lua |

[triage-bot] DIRECTED: pushed 2ecd02d.
README update for the new config option not included — flagging for @dmtrKovalenko since per CLAUDE.md new neovim config options should be documented there. Want me to add a section? Honk-Honk 🪿 |

@dmtrKovalenko Hi, could this please be prioritized? Doing a case-insensitive search is a huge boost to search relevancy, when searching across repos containing multiple languages |
Adds fff::CaseMode and an optional GrepSearchOptions::case_mode that overrides the legacy smart_case toggle when set. smart_case is kept and behaves as before (true => Smart, false => Sensitive) so existing Rust, C, Python, MCP and Lua callers are unaffected. Wires case_mode through the nvim FFI as a trailing optional string and exposes it as config.grep.case_mode and content_search opts.case_mode. Rebased #609 onto main after the grep.rs module split.

Validate case_mode before the bridge.
M.live_grep merges opts.grep without validation. M.content_search validates only the options table. Both paths forward invalid case_mode values to Rust, where unknown values become None and use smart_case.
Use vim.validate() and reject values other than "smart", "sensitive", and "insensitive" before opening the picker or calling grep.search. Cover the live-grep resume fallback as well.

What
Adds
fff::CaseMode { Smart, Sensitive, Insensitive }and a new optionalcase_mode: Option<CaseMode>field onGrepSearchOptions. AddsGrepSearchOptions::effective_case_mode()to resolve the effective mode.Non-breaking
The legacy
smart_case: boolfield is preserved. Whencase_modeisNone, the existing boolean is used (true=>Smart,false=>Sensitive) — identical behavior to before. New callers that needInsensitivesetcase_mode = Some(CaseMode::Insensitive).No public function signatures changed.
Defaultstill emitssmart_case: true, case_mode: None. Existing consumers (fff-c,fff-nvim, benches, tests) compile unchanged.Why this shape
The original PR #561 changed
smart_case: booltocase_mode: CaseModedirectly, which is a breaking field change for anyone constructingGrepSearchOptions. This PR adds the new API alongside the old one so #561 (and future consumers) can adoptcase_modewithout a major version bump.How verified
cargo check -p fff-searchpasses. Internal call sites ingrep.rsroute througheffective_case_mode()so behavior is preserved when onlysmart_caseis set.Co-authored-by: Marko Vejnovic contact@markovejnovic.com
