vim：编译当前缓冲区的函数问题

I have this function to compile my tex files:

我有这个函数来编译我的tex文件：

function! CompileTex()
    silent write!
    call setqflist([])
    echon "compiling with arara ..."
    exec 'lcd %:h'

    if expand("%:p") =~# '\(figuras\|figures\)'
        let mainfile = fnameescape(expand("%:p"))
    else
        let mainfile = fnameescape(Tex_GetMainFileName())
    endif
    let &l:makeprg = 'arara -v ' . mainfile
    silent make!

    if !empty(getqflist())
        copen
        wincmd J
    else
        cclose
        redraw
        echon "successfully compiled"
    endif

endfunction

The first conditional is there because when creating figures I want to compile the current buffer even if there is a main file. However when I call the function in a path that contains "figures" I get

第一个条件是因为在创建数字时我想编译当前缓冲区，即使有一个主文件。但是当我在一个包含“数字”的路径中调用该函数时，我得到了

Error detected while processing function CompileTex:
line 4:
E499: Empty file name for '%' or '#', only works with ":p:h": lcd %:h

and the mainfile variable is set to the main tex file and not to the current buffer as I want.

并且mainfile变量设置为主tex文件，而不是我想要的当前缓冲区。

Try as the error message suggests, and change "lcd %:h" to "lcd %:p:h".

尝试显示错误消息，并将“lcd％：h”更改为“lcd％：p：h”。

Also, you don't need the :exec. Just write it directly, it's an ex command:

此外，您不需要：exec。直接写它，这是一个ex命令：

function! CompileTex()
    silent write!
    call setqflist([])
    echon "compiling with arara ..."
    lcd %:p:h
    ...
    etc.
