# [NAME](#NAME)

Tk::Xrm - X Resource/Defaults/Options routines that obey the rules.

# [SYNOPSIS](#SYNOPSIS)

```
   use Tk;
   use Tk::Xrm;
```

# [DESCRIPTION](#DESCRIPTION)

Using this modules causes Tk's Option code to be replaced by versions which use routines from <X11/Xresource.h> - i.e. same ones every other X toolkit uses.

Result is that "matching" of name/Class with the options database follows the same rules as other X toolkits. This makes it more predictable, and makes it easier to have a single ~/.Xdefaults file which gives sensible results for both Tk and (say) Motif applications.

# [BUGS](#BUGS)

Currently **optionAdd**(*key* => *value*?, *priority*?) ignores optional priority completely and just does **XrmPutStringResource()**. Perhaps it should be more subtle and do **XrmMergeDatabases()** or **XrmCombineDatabase()**.

This version is a little slower than Tk's re-invention but there is more optimization that can be done.
