I get the following error: ```auto Symbol’s value as variable is void: tag-name ``` When running the following: ```auto ("C-c n p" . my/org-roam-find-project) ("C-c n t" . my/org-roam-capture-task) ``` How do I fix this? My config is based on [System Crafters](https://systemcrafters.net/build-a-second-brain-in-emacs/5-org-roam-hacks/) My full [Emacs.org](http://Emacs.org) is [here](https://github.com/pauljamesharper/emacs-from-scratch/blob/master/Emacs.org) ---

For the `FILTER-FN` arg of `org-roam-capture-` I think you need to pass function’s name as a symbol or a lambda function directly like this: ```auto ;; Capture the new task, creating the project file if necessary (org-roam-capture- :node (org-roam-node-read nil (lambda (node) (member "Project" (org-roam-node-tags node)))) :templates '(("p" "project" plain "** TODO %?" :if-new (file+head+olp "%<%Y%m%d%H%M%S>-${slug}.org" "#+title: ${title}\n#+category: ${title}\n#+filetags: Project" ("Tasks")))))) ``` At least I don’t get the same error; it seems to work on my end. ---

Thanks for your replies @nobiot! I already have the **if-new** in my org file. In fact it looks verbatim to me. I am still at a loss. ---

I’m not talking about if-new… sorry the second arg of org-roam-node-read. > [@nobiot](#): > > ```auto > (org-roam-node-read > nil > (lambda (node) > (member "Project" (org-roam-node-tags node)) > > ``` Compare this above with yours for the second argument. If you are still lost, let me know; I will try to be clearer when i’m back to my PC ---

Sorry. Not getting it. Although I found if I delete some Test files the commands will work once. After I create a single Project or Todo file and C-c C-c and try it again I am back to the variable is void stuff. ---

As far as I can tell from above, you are calling this command `my/org-roam-capture-task` and get the error message you originally reported — I have reproduced it on my end. ```auto (defun my/org-roam-capture-task () (interactive) ;; Add the project file to the agenda after capture is finished (add-hook 'org-capture-after-finalize-hook #'my/org-roam-project-finalize-hook) ;; Capture the new task, creating the project file if necessary (org-roam-capture- :node (org-roam-node-read nil (my/org-roam-filter-by-tag "Project")) :templates '(("p" "project" plain "** TODO %?" :if-new (file+head+olp "%<%Y%m%d%H%M%S>-${slug}.org" "#+title: ${title}\n#+category: ${title}\n#+filetags: Project" ("Tasks")))))) ``` In the form that begins with calling `org-roam-capture-`, in the `:node` part, you call `org-roam-node-read`. In it, the second arg, you pass `(my/org-roam-filter-by-tag "Project")`. This is incorrect. Change it to `(lambda (node) (member "Project" (org-roam-node-tags node)))` The entire `defun` should be like this: ```auto (defun my/org-roam-capture-task () (interactive) ;; Add the project file to the agenda after capture is finished (add-hook 'org-capture-after-finalize-hook #'my/org-roam-project-finalize-hook) ;; Capture the new task, creating the project file if necessary (org-roam-capture- :node (org-roam-node-read nil (lambda (node) (member "Project" (org-roam-node-tags node)))) :templates '(("p" "project" plain "** TODO %?" :if-new (file+head+olp "%<%Y%m%d%H%M%S>-${slug}.org" "#+title: ${title}\n#+category: ${title}\n#+filetags: Project" ("Tasks")))))) ``` I cannot test `my/org-roam-project-finalize-hook`, and I don’t have Project as a tag, so I did these to test my proof of concept: - I commented out `(add-hook 'org-capture-after-finalize-hook #'my/org-roam-project-finalize-hook)` - I use “test” as a tag, instead of “Project” This below is the command I tested. It works; it filters my node and only returns the ones with tag “test”. ```auto (defun my/org-roam-capture-task () (interactive) ;; Add the project file to the agenda after capture is finished ;; (add-hook 'org-capture-after-finalize-hook #'my/org-roam-project-finalize-hook) ;; Capture the new task, creating the project file if necessary (org-roam-capture- :node (org-roam-node-read nil (lambda (node) (member "test" (org-roam-node-tags node)))) :templates '(("p" "project" plain "** TODO %?" :if-new (file+head+olp "%<%Y%m%d%H%M%S>-${slug}.org" "#+title: ${title}\n#+category: ${title}\n#+filetags: Project" ("Tasks")))))) ``` ![Screenshot from 2021-12-07 18-51-57](https://global.discourse-cdn.com/free1/uploads/orgroam/original/2X/0/08f139a80e9a7b4b087ccd217afe6feb8ecc384b.png) ---

Not sure if this is doing anything: ```auto (defun my/org-roam-project-finalize-hook () "Adds the captured project file to `org-agenda-files' if the capture was not aborted." ;; Remove the hook since it was added temporarily (remove-hook 'org-capture-after-finalize-hook #'my/org-roam-project-finalize-hook) ``` ---

My code does not touch the other command, `my/org-roam-find-project` but I think it has the same problem. Replace the part where calling the named function with the lambda function; the same principle should apply by the looks of it (untested). Maybe this one works. I don’t know. It’s not part of the call stack you listed above (toggle-debug-on-error). It looks like you copied code from System Crafters. I can’t see what version of Org-roam his code is compatible with. Perhaps you could ask him to update it. ---

I had `;; -*- lexical-binding: t; -*-` in the wrong place. The init.el must have that at the top of the file. My final [Emacs.org](http://Emacs.org) is here with the relevant bit in the **Welcome** section.

I see. Thanks for reporting back. Good to know about the difference between the lexical and dynamic bindings. I don’t fully understand the closure and scope but it’s another instance I can use to learn more about them. ---

I had exactly the same issue, thanks for reminding me about ;; -_- lexical-binding: t; -_-. I use org file as my init file, so I had to put THIS at the very top of my init file: #+BEGIN\_SRC emacs-lisp ;; -_- lexical-binding: t; -_- #+END\_SRC And now everything in [this](https://www.youtube.com/watch?v=CUkuyW6hr18) video works as expected.
