Question

任何人都可以帮我调试为什么自动完成无法在这种情况下工作？（作为一个例子，我在TAB中实际选择Tab键进行自动完成）：

my $variable;

while(<>) {
    if($_ =~ m/$variabTAB/i)

但在这里工作正常：

$second_var = $variabTAB

我相信这是因为第二个案例中有一个单词是自动完成的，换句话说就是用空格包围。它失败了，因为第一个例子有其他字符填充的单词。

Answer 1

你的预感是对的。这一行来自你的完成功能

let substr = matchstr(substr, "[^ \t]*$")       " word till cursor

抓取光标前面的所有非空白字符;在你的例子中m/$variab。

因为它包含斜杠，然后会触发文件完成，这自然不会考虑$variable。

要解决此问题，您可以切换到仅匹配关键字字符（\k*$，默认完成考虑的内容），但这可能会对文件完成情况产生负面影响。

当Word到自动完成不被空白包围时，Vim自动完成失败
