How to render contents of text field in a specific color

[Amir Katz (Outseer)]

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?

Thanks

Hello,

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

https://marketplace.atlassian.com/apps/1211608/color-custom-fields?hosting=server&tab=overview

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...

[Alexey Matveev]

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

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

[Alexey Matveev]

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}"
customFieldObj.setFormValue(newValue)

[Alexey Matveev]

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.

[Alexey Matveev]

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?

[Amir Katz (Outseer)]

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.
