How to render contents of text field in a specific color

I have a multi-line text field (optional). I would like the text (when there is text) to be in displayed in red, which means to surround it with [color:red] <text here> [color] (using square brackets here to avoid rendering :-))

I can probably hack a behaviour that will edit the field value when field changes, but it's really a hack.

Any idea? Any existing solution?

You can use Java Script for it. But it is not a mantainable solution. Or have a look at plugins. For example, like:

The plugin above does not do what I need...

The solution I see is to add a ScriptRunner Behaviour on the field and whenever it changes, add the color coding around it. A really ugly solution...

You can not add a colour coding, using ScriptRunner behaviours.

Thanks @Alexey Matveev _Appfire_ If I modify the field in a Behaviour, it might trigger the Behaviour again and then will go into an infinite that what you mean?

No, I mean that there is no methods in behaviour to change a colour for a field.

I can always set the field value with 

def newValue = "{color:red}" + oldFieldValue + "{color}"

Did you try it? It does not set a colour. 

You need to change the field text renderer to Wiki Style Renderer and then it works. You do that in the field configuration.

Ok. If it works for you, then you can do it:)

Amir, I have server so I can set the renderer.  Is it possible to do something like if the value of the field is >= 0 then green, if it is <0 then red? Do you have an example you can give me?  Also, where do you put this code?

It sounds complicated and you must have ScriptRunner. Also, since it's a long text field, it does not have a single integer value.

What you ca do is this:

  1. Create a behaviour on the field
  2. In the behaviour, read the new field contents
  3. Strip away all wiki-style formatting (which may be there if the user just modified the field)
  4. Set new formatting based on some criteria applied against the text

Thanks a lot Amir, it works for me.
