ggtags VS ctags

Can you access https://elpa.gnu.org in a browser?

The packages available via the built-in package manager once configured do not come from GitHub though they may be developed there. They come from GNU ELPA NonGNU ELPA and MELPA. You would still need internet access though.

To install elisp packages system-wide under the Portage control you can use gs-elpa. Read layman documentation before using it, as gs-elpa represents ELPA repositories as g-sorcery overlays. It currently supports 4 repositories: gnu-elpa, marmalade, melpa and melpa-stable.

I run emacs at work on a system that does not access the internet, so I cannot utilize the package interface that pulls directly from melpa (and elpa etc). Years ago, someone copied a version of melpa into a local directory on the air-gapped server. In my init.el, I setq package-archive to something like (("local-melpa" . "/path/to/the/melpa/dir")) so that it points to this local directory. I'm wondering if there is a tool to facilitate this sort of mirroring? I would like to update my packages on this air-gapped network. I am able to copy files onto the system from a less restricted workstation with internet access. Is it just a matter of unzipping the melpa repo and pointing package-archive to the fresh melpa directory?

https://github.com/leoliu/ggtags works well ; otherwise I use dumb-jump and eglot quite a bit

https://github.com/leoliu/ggtags can also be useful ; and for me ripgrep via https://github.com/leoliu/ack-el or https://github.com/jacktasia/dumb-jump

I get similar connection-security messages when attempting to connect to the package archive at https://elpa.nongnu.org/ —again, in both *Package* and in *eww*—while elpa.gnu.org seems to be just flat out nonresponsive. However, other https sites including https://duckduckgo.com/about and https://twitter.com work just fine.

I am working on adding more packages to NonGNU ELPA, the new package archive enabled by default from Emacs 28 onwards. Compared to GNU ELPA, there is no need for a copyright assignment (the only requirement is that packages do not endorse non-free software, but that is the case for most Emacs-related software to begin with).

You can also install the latest stable version of Org via GNU ELPA by invoking M-x package-install RET org RET.

I also recommend you https://github.com/preservim/tagbar with https://ctags.io/ installed , it will map definitions (functions, enum, struct etc..) to tags and tagbar plugin allows you to open a split window with the mapped list and navigate through your file, it also enabled more advanced features for quick navigation .

grep, Ctags, Cscope, LSP

Vim has the tag feature built-in, which allows it to jump to the tags that were found by a tool like universal ctags using :h CTRL-]. See :help tags for more information on this. Fun fact: this is the approach that Vim uses when you use :help!

Requirements: You need to have a CTags implementation like universal-ctags installed on your system (on every system where you use vim).

Install https://github.com/universal-ctags/ctags

If you are heavy Vim user, you do not need anything else. For just quick browsing, simply use ctags, make sure to use universal ctags (https://ctags.io) not exuberant ctags which are no longer well maintained. Go works out of box.

Other (built-in) tools for file navigation in Vim include: :h :ls and :h :buffer to navigate in your buffer list (i.e. the files you have loaded); everything listed in [https://vimways.org/2018/death-by-a-thousand-files/](romainl's "Death by a Thousand Files" articles in vimways); using tags by installing universal-ctags to generate the tags then using any of the commands in :h tag to navigate them; setting global marks to files you use often with m[UPPERCASE LETTER] and jumping to them with `[UPPERCASE LETTER]; :h :vimgrep…

I have good news for you. Universal Ctags, an Exuberant Ctags fork and essentially its replacement, has fixed this already:

Vim has built-in functionality that works pretty similar to what you want. If you have a tags file (for example, using universal ctags), you can hit Ctrl-] (:h Ctrl-]) to jump to the declaration of any function under your cursor. Or, if you don't have a tags file, you can use gd (:h gd) to jump to a local declaration within the open file.
