Java Mode Tamed (aka `jmt-mode`) is a derived major mode for Emacs that affords better control of the built-in Java mode, particularly in regard to syntax highlighting. For this, it defines customizeable faces to highlight the following features of Java.

• Annotation details
• Delimiters (quotes, various forms of bracket and separator)
• Javadoc details
• Keywords, according to role
• Named literals: `true`, `false`, `null`
• Package-declaration details
• Shebang
• Type identifiers at point of declaration (as opposed to reference)
• Type variables at point of declaration

Additionally it corrects the highlighting of mishandled features, such as:

• Annotations
• Assert statements
• Enhanced `for` loops
• Javadoc block tags
• Method and constructor declarations
• Multi-type catch parameters
• Records
• Static imports

Installation

You can install `jmt-mode` from MELPA using a package manager, e.g. the built-in `package.el`. It should then activate for any loaded file that has either a `.java` extension or `java` shebang.

Alternatively, see `jmt-mode.el` for instructions on manual installation.

Customization

To view a list of the customizeable faces, enter a `jmt-mode` buffer (or otherwise load `jmt-mode`) and type `M-x customize-group <RET> jmt <RET>`. Or look through the `defface` definitions in `jmt-mode.el`.

For reference, a working example of customization is available:

• The author’s `~/.Xresources`.
• Corresponding screen shots: untamed, tamed, and further customized as taming allows.
