dsh-fff

Fff

Fuzzy file finding and indexed content search for DSH: find_files / resolve_file / related_files / fff_grep. Pure-JS path index + subsequence scoring (no native dependencies). Port of pi-fff for the Pi coding agent.

The plugin will be installed here. Keep web if you are unsure.

README

dsh-fff

模糊文件查找 + 索引内容搜索——DSH 插件，移植自 Pi Coding Agent 生态的 pi-fff（FFF = fast fuzzy finder）。

功能

工具说明
find_files模糊路径搜索（fzf 风格多 token：空格分隔、每个 token 必须命中；basename 计双倍、目录段计半，连续片段加分），返回排序路径列表
resolve_file模糊引用 → 单个精确路径（并列给出 runner-up，暴露歧义），结果可直接喂给 read/replace
related_files相关文件：同 stem（.test.ts/.spec.ts/实现配对）→ 同目录 → 兄弟目录
fff_grepripgrep 内容搜索（regex/字面量、模糊 scope、glob 过滤），结果按文件分组带计数

索引：纯 JS 递归遍历工作区（fs.listDir），跳过 .git/node_modules/dist/build 等目录，5 万文件 / 16 层上限；60 秒 TTL 缓存。零 npm 依赖（Pi 原版用原生 @ff-labs/fff-node，动态插件不能 require npm 包，故纯 JS 重写；中型项目性能足够）。

内容搜索：走 subprocess 服务调用 ripgrep（rg --no-heading --line-number）；rg 未安装时给出明确错误并提示使用内置 grep 工具。

安装

dsh plugin --profile <name> add dsh-fff

安装后重启 DSH，find_files / resolve_file / related_files / fff_grep 对所有会话生效（fff_grep 需要本机装有 ripgrep）。

开发

npm test   # 15 用例：子序列打分、多 token、basename/目录权重、排序/截断、相关文件、搜索结果分组、静态求值、工具注册

与 pi-fff 的差异

  • 无原生索引库：纯 JS 路径索引 + 子序列打分（原版为 C++ FFF 索引 + 后台 watcher）；
  • 无编辑器 @... 补全（DSH 聊天输入没有该机制；如需浏览器端文件选择器 UI 可后续加 Client Slot）；
  • read/grep 工具覆盖不做（DSH 内置工具行为不同，模糊解析通过 resolve_file/fff_grep 显式提供）。
