How to disable auto-indent for a specific mode?

How to disable auto-indent for a specific mode?

[Pankaj Jangid]

I am using plantuml-mode for some UML diagrams. But I discovered that
the auto-indent is broken. And the project doesn’t seem to be
active. But to be honest, I haven’t yet contacted the maintainer of the
package. I’ll definitely do.

For the time being, I want to disable auto-indent for this particular
mode? Is there a way to suppress that? Or is this something that is
controlled by a mode specific variable?

A quick look at

https://github.com/skuro/plantuml-mode/blob/develop/plantuml-mode.el

shows that it is using its own indentation function, and it is not
customizable.

You can modify the source code or use a hook to set the local variable
indent-line-function to something else (untested):

(add-hook 'plantuml-mode-hook
          (lambda ()
            (setq indent-line-function (lambda () 'noindent))))

Thanks. This worked for me. I need to look a bit more into it. That I’ll
do. Thanks for pointing to the right direction.

Currently, TAB is following weird indentation rules. That I must fix.
