I'm aware of opening files in readonly mode from shell using vim -R, but how to open a file from inside vim in a separate tab (:tabe <filename>) in readonly mode?
Thanks for your time.
回答1:
To open a file in read only mode in a new tab, use
tab sview /path/to/file
To open the file in the same pane, (without using a new window or tab), use
view /path/to/file
Note that tab view /path/to/file does not open a new tab.
回答2:
You can open a file in readonly mode from inside vim:
:view /path/to/file
or from command line:
$ vim -M /path/to/file
回答3:
vim -M filename opens the file in readonly mode.
回答4:
Just open your file by using :tabe <filename>, then enter :view. It will automatically switch to read-only mode.
回答5:
Try :tabedit +set\ noma|set\ ro FILE; this will open FILE in a new tab with modifiable off and readonly on, preventing you from modifying or writing the file. If you just want readonly, omit the noma set. Might be convenient to remap this to another command.
回答6:
vim -R /path/to/file
vim -m /path/to/file
Read-only mode. Modification in text is allowed but you cannot write (no saving).
vim -M /path/to/file
Even modification in text is not allowed.

Something that works for me:
:vnew path/to/file
and once the file is opened, give the view command:
:view
