Is that possible to save and restore the nerdtree status? What collapsed and what expanded.

[sgon00]

Hi, I am using vim session vim -S. I have read all the issues related to vim session. I know I can not save nerdtree to the session file and I know I'd better quit the nerdtree before I mksession. I am OK to reopen the nerdtree everytime when I launch vim. The only problem and headache I have is how to possibly load the last nerdtree listing status? To resotre what directories are collapsed and what directories are expanded. Thank you very much.

Have you seen #248? There is a separate project mentioned in there that was written to provide this functionality. It hasn't been touched in a while, so your mileage may vary.

@PhilRunninger thank you very much for the reply. I read that issue before. It was talking about bookmark. I never use bookmark before. and Which separate project do you mean? Do you mean https://github.com/jistr/vim-nerdtree-tabs? In the project readme.md, it does not mention anything about restoring status. I installed that plugin. I don't know how to make it store my nerdtree status. After the installation, I tried, the status is not restored.

Sorry. I should have been more specific. The project is https://github.com/scrooloose/nerdtree-project-plugin.

@PhilRunninger thanks a lot for the reply. maybe I am stupid. I tried my best but I still don't figure out how to use it. After the installation:

• I did touch ~/.NERDTreeProjects even if this might not be necessary.

• When execute :NERDTreeProjectSave abc in NERD Tree buffer window, it reports:

Error detected while processing function 266[7]..269[13]..279:
line    3:
E716: Key not present in Dictionary: getDirChildren()
E15: Invalid expression: a:rootNode.getDirChildren()

• When execute :NERDTreeProjectSave abc in non-nerdtree buffer window, it reports:

E121: Undefined variable: b:NERDTree
E116: Invalid arguments for function 266

I really need a doc on how to use it. Sorry about all the troubles and questions. Thanks a lot for your time.

I'm not surprised you're seeing these errors. A lot has changed in NERDTree since that project was last touched 3 years ago. I'll take a look at this, and see about moving it into NERDTree. I don't have write access to that project, and I'm pretty sure Marty's not interested in updating it.

@PhilRunninger thank you very much for this help. This is really important to a NerdTree plugin. I really don't understand why this is not implemented all this years. Without this functionality, I have no reason to use this plugin instead of the built-in netrw. Thank you very much.
