counsel-etags did not auto update TAG file.

[jason--liu]

This is my counsel-etags config. counsel-etags have updated to latest.

  (add-to-list 'load-path "~/.spacemacs.d/site-lisp/etags/")
  (require 'counsel-etags)
  (define-key evil-normal-state-map (kbd ", g d") 'counsel-etags-find-tag-at-point)
  (define-key evil-normal-state-map (kbd ", g t") 'counsel-etags-grep)
  (define-key evil-visual-state-map (kbd ", g t") 'counsel-etags-grep)
  ;; Don't ask before rereading the TAGS files if they have changed
  (setq tags-revert-without-query t)
  ;; Don't warn when TAGS files are large
  (setq large-file-warning-threshold nil)
  ;; How many seconds to wait before rerunning tags for auto-update
  ;; (setq counsel-etags-update-interval 180)
  (eval-after-load 'counsel-etags
    '(progn
       ;; counsel-etags-ignore-directories does NOT support wildcast
       (add-to-list 'counsel-etags-ignore-directories "build")
       (add-to-list 'counsel-etags-ignore-directories "build_clang")
       ;; counsel-etags-ignore-filenames supports wildcast
       (add-to-list 'counsel-etags-ignore-filenames "TAGS")
       (add-to-list 'counsel-etags-ignore-filenames "*.json")))
  ;; Setup auto-update
  (add-hook 'prog-mode-hook
            (lambda ()
              (add-hook 'after-save-hook
                        'counsel-etags-virtual-update-tags 'append 'local)))
  (add-hook 'after-save-hook 'counsel-etags-virtual-update-tags)

When I update a C file and autosaved, use ,g d to navigate, it still jump to origin position, did not jump to the new position; But after I force updated the TAG file, it can navigate normally. Please see below gif :

As the gif shows, the memblock_reserved_size function was originally at line 1544, then I added some blank lines before the function and saved it. Use , g d, it still jumped to 1544, however the function is at line 1550 now.

I tested the latest version. It's working.

Below code is enough,

 (add-hook 'prog-mode-hook
            (lambda ()
              (add-hook 'after-save-hook
                        'counsel-etags-virtual-update-tags 'append 'local)))

Change counsel-etags-update-interval to a smaller number.

Hi @redguardtoo I have updated my ini config

  (add-to-list 'load-path "~/.spacemacs.d/site-lisp/etags/")
  (require 'counsel-etags)
  (define-key evil-normal-state-map (kbd ", g d") 'counsel-etags-find-tag-at-point)
  (define-key evil-normal-state-map (kbd ", g t") 'counsel-etags-grep)
  (define-key evil-visual-state-map (kbd ", g t") 'counsel-etags-grep)
  ;; Don't ask before rereading the TAGS files if they have changed
  (setq tags-revert-without-query t)
  ;; Don't warn when TAGS files are large
  (setq large-file-warning-threshold nil)
  ;; How many seconds to wait before rerunning tags for auto-update
  (setq counsel-etags-update-interval 1)
  (eval-after-load 'counsel-etags
    '(progn
       ;; counsel-etags-ignore-directories does NOT support wildcast
       (add-to-list 'counsel-etags-ignore-directories "build")
       (add-to-list 'counsel-etags-ignore-directories "build_clang")
       ;; counsel-etags-ignore-filenames supports wildcast
       (add-to-list 'counsel-etags-ignore-filenames "TAGS")
       (add-to-list 'counsel-etags-ignore-filenames "*.json")))
  ;; Setup auto-update
  (add-hook 'prog-mode-hook
            (lambda ()
              (add-hook 'after-save-hook
                        'counsel-etags-virtual-update-tags 'append 'local)))
  ;; (add-hook 'after-save-hook 'counsel-etags-virtual-update-tags)

and set counsel-etags-update-interval to 1 sec. But still it is not update automaticlly. Is there any log can help to find the problem ?

[redguardtoo]

(setq counsel-etags-debug t). Make sure you have ctags installed and create tags file at least once in project root.

[jason--liu]

Hi @redguardtoo Yes, I have installed ctags

ctags --version
Universal Ctags 0.0.0(b7439756), Copyright (C) 2015 Universal Ctags Team

  URL: https://ctags.io/
  Optional compiled features: +wildcards, +regex, +iconv, +option-directory, +packcc

and TAGS was scaned and created at the first time. After I set (setq counsel-etags-debug t) and change a file and save it, after the interval time I did not see any counsel-etags log in Message buffer.

[redguardtoo]

Have you tested with a minimum project? See readme

[jason--liu]

@redguardtoo I have just tested the toy project in readme, unfortunately, it did not auto update TAG.

[redguardtoo]

Tomorrow install the latest counsel-etags and turn of debug flag. I need see the debug output.

I also need see the value of after-save-hook.

[jason--liu]

Hi, @redguardtoo I have updated the latest counsel-etags. please see the log

As the pic shows, the fn func was original at line 7.After I change the file, the func should be line 10. But it still jump to Line 7

Please ignore the error log, that' ycmd log(it could be conflict with counsel-etags)?

[redguardtoo]

There is no message in update tags in .... So tags file is not re-generated.

Insert (setq counsel-etags-update-interval 3) into init.el and try to reproduce the issue.

[jason--liu]

@redguardtoo After I Insert (setq counsel-etags-update-interval 3) (before was 1 sec) and wrote the file and saved it After a while, there were no more logs..(even the counsel-etags-virtual-update-tag log)

and it still jump to line 7, which should be line 10.
