Vimscript是否允许多行字符串？

Question

Vimscript是否允许多行字符串？

python和ruby命令允许格式: :python << EOF

你能用字符串做类似的事吗？

Answer 1

Vimscript允许通过使用反斜杠启动下一行继续前一行,但这不像你在Ruby,PHP或Bash中找到的heredoc字符串那样方便.

let g:myLongString='A string
\ that has a lot of lines
\ each beginning with a 
\ backslash to continue the previous one
       \ and whitespace before the backslash
       \ is ignored'

看一下有关续行的相关文档.

Vimscript多行字符串,点运算符:

枚举分配并包括前一个分配可让您连接线

let foo = "bar" 
let foo = foo . 123 
echom foo                      "prints: bar123 

使用复合字符串连接运算符dot equals:

let foo = "bar" 
let foo .= 123 
echom foo                      "prints: bar123

列出您的字符串和数字并加入它们:

let foo = ["I'm", 'bat', 'man', 11 ][0:4] 
echo join(foo)                                   "prints: I'm bat man 11 

与上面相同,但加入数组切片

let foo = ["I'm", 'bat', 'man', [ "i'm", "a", "mario" ] ] 
echo join(foo[0:2]) . " " . join(foo[3]) 
"prints: I'm bat man i'm a mario

行开头的反斜杠允许行继续

let foo = "I don't think mazer 
  \ intends for us to find 
  \ a diplomatic solution" 
echom foo 

let foo = 'Keep falling,  
  \ let the "grav hammer" and environment 
  \ do the work' 
echom foo 

打印:

I don't think mazer intends for us to find a diplomatic solution
Keep falling, let the "grav hammer" and environment do the work

在一个函数中隐藏你的秘密文本和大多数古代文本:

function! myblockcomment() 
    (*&   So we back in the club 
    //    Get that bodies rocking 
    !#@   from side to side, side side to side. 
    !@#$   =    %^&&*()+
endfunction 

自由格式文本的内存位置是它位于磁盘上的文件.该函数永远不会运行,或者解释器会呕吐,所以直到你使用vim反射来实现myblockcomment()然后做你想做的任何事情.除了睡觉和混淆之外,不要这样做.

您不能用于<<创建字符串，但可以用于<<创建字符串列表。看:help :let=<<

下面是 vim 文档中的示例

            let text =<< trim END
               if ok
                 echo 'done'
               endif
            END
