I have here an nginx config. I need to comment out blocks in it:

...things I want...
...things I don't want...
...things I want...

The things are 30-50 lines long, and I won't backup and delete them. I also don't want write #s to the beginning of 30-50 code lines, and I also don't want to script/configure my text editor to do this. I think it is a quite trivial feature.

I tried

...things I want...
/*
...things I don't want...
*/
...things I want...

But it doesn't work. Is it really an unsupported feature in the nginx?

  • Modern editors won't need to be configured. Highlight the rows and run the comment command (e.g. ctrl + / in Atom and VSCode). For Vim, you'll need to configure it, e.g. can install the vim-commentary plugin. – Dennis Mar 27 '18 at 10:06

    @Dennis In my opinion, to install complex development environments on remote servers, and to run them as root, just for this would be an unfeasible solution for this problem. – peterh Aug 09 '18 at 15:27

    @Dennis @peterh vim-commentary is not necessary in this case: visual block insert will insert a char at the start of the block for every line. So make a block selection consisting of the first char of the line for every line you want to comment, then do I#<esc>. It's like magic. Check :h v_b_i in vim for more details. – Dan Locks Aug 23 '22 at 16:37
  • @peterh You don't need to install complex development environments on remote servers while root, that type of situation is unsafe and should be avoided in the first place. Development environments are a thing. If you must do it live, backup the file as dr__ suggests and use Dan's suggestion of visual block insert in Vim. – Dennis Jan 25 '23 at 22:10
  • @Dennis Right, so it can be done. Time to learn a little bit more vi. :-) – peterh Jan 25 '23 at 22:30

Nginx configuration files do not support comment blocks; they only accept # at the beginning of a line for a comment. You can also have a valid statement followed by a # and then a comment on the same line. (Source.)

If you have between 30 and 50 lines to ditch out I'd suggest, to avoid confusion, to remove the block entirely (after making a copy of the file, unless you're using a version control system such as Git).

  • Today I happen to use ansible to deploy configs and it has a templating engine supporting long comment blocks. Nginx does not need to see them, it can only see the processed configuration. – peterh Aug 06 '23 at 15:52
