这我理解不了了 
姑且建议您把 ./ 改成 .，应该就可以用了。
我用 citre 在 Linux kernel 直接搜索 symbol，生成的选项好像可以直接把 vertico 卡死…
有没有可能加一个 max_entries 给 citre 限制查询返回的数量?
还是说给 vertico 加个限制其实会更好吗？
大佬，公司开发服务器上多人使用 citre时，citre-tags–imenu-tags-from-temp-tags-file 似乎不会主动删除其产生的 /tmp/citre-imenu.tags，导致多人使用的时候该文件不能被其他人更新，有解决方法么？
应该修好了，您看一下。
大佬我按照文档配置了一下，但它似乎不能正常工作

company-backends如下：
((:separate company-capf company-yasnippet))
在一个打开的html文件中不能正确提示和补全btn-primary等样式
但是tags文件看起来是正常的：
我同时还使用了lsp-mode，但我感觉应该不是lsp的问题，因为lsp在字符串里面没有补全信息
BTW, 上面能补全的内容可以使用citre-jump进行跳转：
配置文件(config.el)中只写了两行:
(require 'citre)
(require 'citre-config)
我仔细看了，但是补全变成了这样：
有些elisp的语法看的不是很懂，就直接复制粘贴了，下面是粘贴的内容(省略了一下)：
(define-advice xref--create-fetcher (:around (-fn &rest -args) fallback)
(defun lsp-citre-capf-function ()
(defun enable-lsp-citre-capf-backend ()
(add-hook 'citre-mode-hook #'enable-lsp-citre-capf-backend)
(defmacro citre-backend-to-company-backend (backend)
(citre-backend-to-company-backend tags)
(citre-backend-to-company-backend global)
(setq company-backends '((company-capf ...
请问是这样弄吗，实在是不太懂，本来是想用lsp-bridge的citre，但是lsp-bridge安装在doom上有很多奇怪的问题，就想着切换到citre来用，奈何两条路都不好走
你可以参考下我以前发的帖 怎么在 doom 里用 lsp-bridge
或者在 doom 里用 eglot，
(defalias #'my-eglot-citre-capf
(cape-super-capf #'eglot-completion-at-point #'citre-completion-at-point))
(add-hook 'eglot-managed-mode-hook
(defun my-toggle-citre-eglot-capf ()
(if (eglot-managed-p)
(add-to-list 'completion-at-point-functions #'my-eglot-citre-capf))))
这个snippet也是我写的
应该是因为你的 lsp 的补全项太多了，然后 citre 的补全都压在最底下。
citre-auto-enable-citre-mode 和 magit 一起用的话，在打开 git 项目中的文件的时候，似乎经常会卡住，然后只能按 C-g 退出.
这是我的配置：
(defvar bootstrap-version)
(let ((bootstrap-file
(expand-file-name "straight/repos/straight.el/bootstrap.el" user-emacs-directory))
(bootstrap-version 6))
(unless (file-exists-p bootstrap-file)
(with-current-buffer
(url-retrieve-synchronously
"https://raw.githubusercontent.com/radian-software/straight.el/develop/install.el"
'silent 'inhibit-cookies)
(goto-char (point-max))
(eval-print-last-sexp)))
(load bootstrap-file nil 'nomessage))
(straight-use-package 'magit)
(straight-use-package 'citre)
(require 'citre)
(require 'magit)
(add-hook 'find-file-hook #'citre-auto-enable-citre-mode)
操作：
straight-use-package 上，按 M-.。正常情况下会打开 straight.el 文件，但实际上会卡住，只能按 C-g退出。
这是 backtrace:

继续借大佬的楼请教一下，糊了一个保存文件后自动更新 tags的轮子，为了不卡，调用了shell，目前几乎可以工作，使用中有下面的问题。
下面的代码中，如果在 get-ptag-from-cache 中直接调用 set-ptag-to-cache，emacs就会被卡住，但 M-x 执行 set-ptag-to-cache 时，又没有问题，请大佬解惑
(defun citre-auto-update-get-ptag-from-cache (ptag)
"return ptag's value from `citre-auto-update-ptag-cache';
or update cache if value is nil"
(let* ((project-root (funcall citre-project-root-function))
(pvalue (assoc-default ptag (gethash project-root citre-auto-update-ptag-cache))))
(unless pvalue
(message "Please run `citre-auto-update-set-ptag-to-cache', and will update tagsfile next time.")
;; (citre-auto-update-set-ptag-to-cache) ;; if automatic do this, eamcs been blocked, UNKNOWN CASE
)
pvalue))
(defun citre-auto-update-set-ptag-to-cache ()
"read CITRE_CMD and TAG_PROC_CWD from tagsfile, write to `citre-auto-update-ptag-cache'.

(interactive)
(let* ((tagsfile (citre-tags-file-path))

(project-root (funcall citre-project-root-function)))
(puthash project-root
(list (cons "CITRE_CMD" cmd-ptag) (cons "TAG_PROC_CWD" cwd-ptag))
citre-auto-update-ptag-cache)))
感谢作者，我想用它看c++代码，首次输入 citre-jump+的时候转到定义处，不要弹出框让我选，再次输入的时候就在.h 和.cpp里来回切换，不知道这个好实现吗
大佬好久不出现了，继续在大佬的基础上造轮子，利用 read-string查询任何tag，match 使用 substr 方法：
(defun citre-jump-from-input ()
"Like `citre-jump', but get symbol `read-string'
"
(interactive)
(let* ((symbol (read-string "symbol: "))
(tagsfile (citre-tags-file-path))
(buf (current-buffer))
(defs (citre-tags-get-tags
tagsfile symbol `substr
:filter (or (citre-tags--get-value-in-language-alist
:definition-filter symbol)
(citre-tags-definition-default-filter symbol))
:sorter (or (citre-tags--get-value-in-language-alist
:definition-sorter symbol)
citre-tags-definition-default-sorter)
:require '(name ext-abspath pattern)
:optional '(ext-kind-full line typeref scope extras)))
(result (cdr defs)))
(if (null defs)
(user-error "Can't find definition: %s" symbol))
(citre-jump-show defs)
(citre-after-jump-action buf)))
巧了，我刚用 consult 糊了个类似的功能

不错啊 用起来看起来很完美
