Open a file in a tab in vim in readonly mode

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>开发者_运维知识库;) in readonly mode?

Thanks for your time.

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.

You can open a file in readonly mode from inside vim:

:view /path/to/file

or from command line:

$ vim -M /path/to/file

vim -M filename opens the file in readonly mode.

Just open your file by using :tabe <filename>, then enter :view. It will automatically switch to read-only mode.

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.

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.

Something that works for me:

:vnew path/to/file

and once the file is opened, give the view command:

:view
