如何控制vim度量段落的方式

Question

在vim中编辑latex代码时，我经常输入gwap来重新对齐当前段落。不幸的是，当段落包含等式或其他类似的latex控制代码时，格式就会完全混淆。

例如，如果我试图重新对齐对齐的段落

Our network model follows that of Nakajima et
al.~\\cite{nakajima_robustness_2010} which is in turn based on the model of Li
et al.~\\cite{li_yeast_2004}. We define the dynamics of a network through the
following recurrence relation
\\[
X_i^{t+1} = \\left\\{ \\begin{array}{cl}
  1 & \\textrm{if $\\sum_j J_{ij} X_j^t > 0$} \\\\
  0 & \\textrm{if $\\sum_j J_{ij} X_j^t < 0$} \\\\
  \\theta_i & \\textrm{if $\\sum_j J_{ij} X_j^t = 0$}
\\end{array} \\right.
\\]
$X_i^t \\in \\{0, 1\\}$ is the expression state of gene $i$ at time point $t$.
$J_{ij}$ represents the regulatory effect of gene $j$ on gene $i$. $J_{ij} >
0$, $J_{ij} < 0$ and $J_{ij} = 0$  imply activation, repression and the absence
of regulation respectively. $\\theta_i$ is the constitutive expression state of
gene $i$.

然后我就得到了这个烂摊子：

Our network model follows that of Nakajima et
al.~\\cite{nakajima_robustness_2010} which is in turn based on the model of Li

                       \\textrm{if $\\sum_j J_{ij} X_j^t < 0$} \\\\ \\theta_i &
                       \\textrm{if $\\sum_j J_{ij} X_j^t = 0$} \\end{array}
                   \\right.  \\] $X_i^t \\in \\{0, 1\\}$ is the expression state of
                   gene $i$ at time point $t$.  $J_{ij}$ represents the
                   regulatory effect of gene $j$ on gene $i$. $J_{ij} > 0$,
                   $J_{ij} < 0$ and $J_{ij} = 0$  imply activation, repression
                   and the absence of regulation respectively. $\\theta_i$ is
                   the constitutive expression state of gene $i$.

我如何告诉vim段落不应该像\[ \] \begin{} \end{}那样跨越代码

谢谢，约翰。

段落的概念来自nroff宏的旧vi继承(不管是什么:-)；它不能被实质性地改变。最近，support custom definitions via regular expressions的vim_dev mailing list上出现了一个补丁。

到目前为止，您必须通过使用视觉选择来解决这个问题：Vjjjgw。或者，您可以为Tex段落编写自己的文本对象。
