Syntax colorization (parameters)

[Danieleeee]

Hi,
I notice this behavior (po_* parameters):

Can you set this behavior depending on IN and OUT keys (different colors)?
So we have colorized variables in input and output.

Consider that we can have IN OUT together:

It's very useful, so in every part of the code we can easily recognize the input and output variables:

@zabel-xyz , you can use this in your plsql.tmLanguage, tested, it works:

<dict>
            <key>match</key>
            <string>(?i)(\b\w+\b)(?=\s*IN\s+|\s*IN\s+OUT\s+|(?<!IN\s)(?=\s*OUT\s+))</string>
            <key>name</key>
            <string>variable.parameter.oracle</string>
 </dict>

Do you think it's better to use different colors for parameters that ends with IN, IN OUT, OUT?

Colors are defined by the theme you are using.
I'm not sure there is one that takes into account different types of variables (in, out)
(others comments in your PR #23)

Colors are defined by the theme you are using.

Templates can be customized, bu we must set different variable name for in and out parameter.
variable.parameter.oracle is generic, you can use:

variable.parameter.in.oracle
variable.parameter.out.oracle

If we use the same name it's difficult to have different colors.
