Here's a screenshot of an editing session which makes use of the three
new features:
1) 'cursorbind'
Both windows have 'cursorbind' set - ok, so you can't actually see
this, but trust me ;) So in the screenshot, the cursor is on the word
"however" in both windows. The use of 'cursorbind' works well for
binding windows of different sizes; obviously in some other
circumstances 'scrollbind' is still the better choice.
2) 'conceal'
The upper window has a 'conceallevel' of 2, which means that concealed
text is hidden unless a custom replacement char is specified. This has
been used to render LaTeX codes thusly:
| \left( |
(
|
| \right) |
)
|
| \left[ |
[
|
| \right] |
]
|
| \cdot |
.
|
| \gamma |
Y
|
| \theta |
T
|
| \circ |
o
|
| \begin{equation} |
>
|
| \end{equation} |
<
|
Note that \label{eqn:tlin1}
in the lower window has been rendered as just eqn:tlin1 in the upper. This is
made simple by the new "concealends" flag for regions which causes just
the matching endgroups to be hidden. "concealends" has also been used
for the inline math ($...$) regions which cleans up the upper window
considerably.
3) :ownsyntax
In the upper window, which is obviously a sort of "print preview" ;) I
needed a slightly different syntax scheme. Firstly the maths is not
highlighted in a separate colour, and secondly the matching of "\begin{equation}" had to be
changed to make the
character replacement work as desired.
Therefore, a hacked tex.vim, named tex2.vim, was loaded into the
upper window with :ownsyntax tex2
The two windows, although on the same file, now have independent syntax
highlighting.
