ctrl-a and ctrl-e are handy shortcuts that work in terminal-based REPLs, so they should probably work in clj-swingrepl too. There are more shortcuts in this category (yank?).

ctrl-a conflicts with "Select all" though, so maybe this should be customizable.

It would be nice if clj-swingrepl colored the *err* output red.

I recall SLIME/Swank doing something like this.

Is there a way when creating a repl with make-repl-jframe to start in a specific namespace and not the user namespace?

clj-swingrepl should use SystemLookAndFeel by default, and there should be a new option to disable this or set the look-and-feel.

Before that is implemented, Linux users can start Java with:
-Dswing.defaultlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel

and Windows users with:
-Dswing.defaultlaf=com.sun.java.swing.plaf.windows.WindowsLookAndFeel

There are multiple issues.

1. :hooks [leiningen.hooks.javac] no longer exists?
2. Something that causes this when lein running:

Exception in thread "main" java.lang.RuntimeException: java.lang.ClassNotFoundException: org.dipert.swingrepl.main

If I open several clj-swingrepls, they all have the title "Clojure 1.x.y REPL". It would be nice to provide a function (title "my title") to set the window title after the REPL has already been started.

Backspace and Delete handling is broken in several cases. The characters [ and ] below are used to indicate the beginning and end of the text selection, respectively. The character | is used to indicate the cursor position.

In this state, pressing Backspace or Delete causes the prompt text to be deleted:

[user=> ]|"xyz"

the same happens in this state:

[user=> "xy]|z"

JConsole should not permit deleting the prompt text.

In this state, pressing Backspace or Delete does not delete anything:

us|[er=> "xyz"]

JConsole should instead delete the input text without deleting any of the prompt text.

Keeping a clj-swingrepl open for a day (192MB heap, 64 bit Java 7u3, Windows) sometimes causes a memory leak and subsequent tracebacks:

java.lang.reflect.InvocationTargetException

Pressing Ctrl-D to close a clj-swingrepl window sometimes propagates the key/close event to another window, closing more than the REPL than you intended to close. This happens even if the other REPL is in another process.

Tested on Windows; might not happen elsewhere.
