光泽的长距离移动箭头

Question

我有一个关于使用 gb4e 绘制箭头的问题。目前，我正在尝试使用下面链接中描述的方法。当我绘制长距离箭头（如 (5)）时，会出现问题。如下图所示，该线与光泽交叉。我想绘制水平线，如示例 (1)。我该如何消除交叉点？

光泽的运动箭头

\usepackage{tikz}
\usetikzlibrary{calc}
\newcommand\tikzmark[1]{\tikz[remember picture, baseline=(#1.base)] \node[anchor=base,inner sep=0pt, outer sep=0pt] (#1) {#1};}

% This code from http://tex.stackexchange.com/q/55068/2693
\tikzset{

    ncbar/.style={

        -- (\tikztotarget)
    },

Answer 1

没有办法完全自动地完成此操作，即每当光泽线换行时就断开箭头。但可以定义另外两种箭头样式来单独绘制箭头。

我制作了两种新样式的箭头，lbar它们rbar在主连接线的左侧或右侧都有额外的段。

然后我修改了该\arrow命令以接受可选参数[l]或[r]指定右或左部分箭头。当未指定可选参数时，该\arrow命令的工作方式与以前相同。

然后，要制作部分箭头，您只需标记要连接的相关部分。（请注意，要使光泽线中的单词正确排列，您需要在光泽线中留出一个空组来进行描摹。）

这是一个完整的例子：

\usepackage{tikz}
\usetikzlibrary{calc}
\newcommand\tikzmark[1]{\tikz[remember picture, baseline=(#1.base)] \node[anchor=base,inner sep=0pt, outer sep=0pt] (#1) {#1};}

% This code adapted from http://tex.stackexchange.com/q/55068/2693

        -- ($(\tikztostart)!#1!\pgfkeysvalueof{/tikz/ncbar angle}:(\tikztotarget)$)
        -- ($(\tikztotarget)!($(\tikztostart)!#1!\pgfkeysvalueof{/tikz/ncbar angle}:(\tikztotarget)$)!\pgfkeysvalueof{/tikz/ncbar angle}:(\tikztostart)$)
        -- (\tikztotarget)
    },
    rbar/.style={% _____| shape
        to path=(\tikztostart)
        -- ($(\tikztostart)!#1!\pgfkeysvalueof{/tikz/ncbar angle}:(\tikztotarget)$)
        -- ($(\tikztotarget)!($(\tikztostart)!#1!\pgfkeysvalueof{/tikz/ncbar angle}:(\tikztotarget)$)!\pgfkeysvalueof{/tikz/ncbar angle}:(\tikztostart)$)
    },
    lbar/.style={% |_____ shape
        to path=
          ($(\tikztostart)!#1!\pgfkeysvalueof{/tikz/ncbar angle}:(\tikztotarget)$) 
        -- ($(\tikztotarget)!($(\tikztostart)!#1!\pgfkeysvalueof{/tikz/ncbar angle}:(\tikztotarget)$)!\pgfkeysvalueof{/tikz/ncbar angle}:(\tikztostart)$)
