Exiting a block enclosed in curly braces in Sublime - sublimetext2

Question

Say if I have the following code in Sublime:
if (condition) {
// code
}
When my cursor is at the end of // code, I would like to set a key bind (e.g. Tab) that will exit the if-statement block and move it to the end of }. Thanks.

The BracketHighlighter plugin can provide this functionality natively... sort of. In its example shortcuts file, Example.sublime-keymap, there is a "Go to Right Bracket" example key binding:
// Go to right bracket
{
"keys": ["ctrl+alt+super+down"],
"command": "bh_key",
"args":
{
"lines" : true,
"plugin":
{
"type": ["__all__"],
"command": "bh_modules.bracketselect",
"args": {"select": "right"}
}
}
},
The only problem is that the called bracketselect command moves the cursor to the left side of the right bracket, requiring another keypress to fully escape from the block. I don't think that's what you want.
Worry not! Thankfully, BracketHighlighter provides a very intuitive plugin API, and I found that I could modify the bracketselect plugin to create a command that would escape from a bracket-enclosed block—basically the same as bracketselect, but it moves the cursor to the right side of the closing bracket rather than the left, and doesn't need any extra arguments.
You'll first need to install BracketHighlighter if you haven't yet.
Next, save blockescape.py (see below if the link ever dies) to
Preferences -> Browse Packages... -> BracketHighlighter/bh_modules/blockescape.py
Then, add this entry to the top of your user key bindings (Preferences -> Key Bindings — User):
{
"keys": ["tab"],
"command": "bh_key",
"args":
{
"lines" : true,
"plugin":
{
"type": ["__all__"],
"command": "bh_modules.blockescape"
}
}
},
I wouldn't recommend using tab as your trigger key, because tab has an important role already with expansions. Of course, you could define a special context in which to use tab, but that is up to you.
In case Github is ever down, here's the plugin code:
import bh_plugin
import sublime
DEFAULT_TAGS = ["cfml", "html", "angle"]
class BlockEscape(bh_plugin.BracketPluginCommand):
def run(self, edit, name, tags=DEFAULT_TAGS):
current_left, current_right = self.selection[0].begin(), self.selection[0].end()
left, right = self.left, self.right
first, last = left.end, right.begin
if left.end != right.end:
if name in tags and left.size() > 1:
first, last = right.begin + 1, right.begin + 1
if first == current_left and last == current_right:
first, last = right.end, right.end
else:
first, last = right.begin, right.begin
if first == current_left and last == current_right:
first, last = right.end, right.end
else:
# There is no second bracket, so just select the first
if name in tags and left.size() > 1:
first, last = left.begin + 1, left.begin + 1
else:
first, last = right.end, right.end
if first == current_left and last == current_right:
first, last = right.end, right.end
self.selection = [sublime.Region(first+1, last+1)]
def plugin():
return BlockEscape
Since I more or less hacked the plugin together, it might not work properly. In that case, feel free to edit it yourself or leave a comment on the Gist page.

You can add the $0 in a snippet to tab to that location:
<snippet>
<description>If Condition</description>
<content><![CDATA[if (${1:/* condition */}){
${2:/* code */}
}${0}]]></content>
<tabTrigger>if</tabTrigger>
<scope>source.c</scope>
</snippet>
