After reading your question about three times, I finally realized that you were looking for one hotkey to perform both operations. Whoops.
Your request sounds like the Ctrl+Shift+; hotkey of the Smart Semicolon Eclipse plugin. While adding semicolons of a genius-level IQ would probably require an entirely new Sublime Text 2 plugin, you can easily create a smart semicolon–esque key binding with Sublime Text's Macros. I actually didn't know about them until now!
In this case, recording the macro yourself is actually the fastest way to create it, rather than copying and pasting a new file (and now you'll have the experience for making more). First, open a new file and type in your favorite garbage line:
Lord Vetinari's cat|
Then move the caret to anywhere within the line:
Lord Veti|nari's cat
Now, press Ctrl+Q, the hotkey for Tools -> Record Macro. If the status bar is enabled, it will notify you that it is "Starting to record [a] macro". Press End (if you don't have an End key, skip to below), then ;, then Enter. Finally, press Ctrl+Q again to stop recording. When you do, the status bar will display "Stopped recording macro". Check that your macro is working by hitting Ctrl+Shift+Q on a code segment of your choosing.
Just pressing Enter will adjust indentation on the next line accordingly as long as the "auto_indent" setting is set to true. See Preferences -> Settings – Default, line 59.
When you're satisfied, save your new macro with Tools -> Save Macro.... I saved mine as Packages/User/smart-semicolon.sublime-macro. My file looked something like this; feel free to copy it if you can't or won't make the macro manually:
[
{
"args":
{
"extend": false,
"to": "eol"
},
"command": "move_to"
},
{
"args":
{
"characters": ";"
},
"command": "insert"
},
{
"args":
{
"characters": "\n"
},
"command": "insert"
}
]
"extend": false, just means that the macro won't add any text to the working selection. Read more about the options for commands at the Unofficial Docs Commands Page.
Now that you have your macro, we can give it a custom key binding. Add the following lines to your Preferences -> Key Bindings – User file:
{ "keys": ["ctrl+shift+;"], "command": "run_macro_file", "args": {"file": "Packages/User/smart-semicolon.sublime-macro"}, "context":
[
{ "key": "selector", "operator": "equal", "operand": "source.java" }
]
},
Replace Ctrl+Shift+; with whatever key binding you prefer, save your file, and give it a shot. The "context" array restricts the key binding to Java files (see the Unofficial Docs Key Bindings page for more information on contexts); if you want the key binding to be active everywhere, use this line instead:
{ "keys": ["ctrl+shift+;"], "command": "run_macro_file", "args": {"file": "Packages/User/smart-semicolon.sublime-macro"} },
This NetTuts+ article has much more information on macros and binding them to keys; I referenced it often. This UserEcho post looks like it has more information on making the insertion more extensible.
