Question

我尝试使用 F4 添加作者和其他一些信息。

但是当我打开* .c或其他文件（不是* .sh），然后按 F4 时，它会显示E488尾随字符。

此外，当尝试更新信息时，它符合E20标记未设置。

还有更多问题，当我尝试使用时 let suff = expand("%:e")获取java文件扩展名，然后if suff == "java"并发现该suff不等于“java”，为什么？

这是我的vim配置：

" Add Author Information
map <F4> :call TitleDet()<CR>'s

function AddTitle()
    call append(0,"/*========================================")
    call append(1,"#")
    call append(2,"# Author: xxx ")
    call append(3,"#")
    call append(4,"# Email: xxx@gmail.com")
    call append(5,"#")
    call append(6,"# Last modified: ".strftime("%Y-%m-%d %H:%M"))
    call append(7,"#")
    call append(8,"# Filename: ".expand("%:t"))
    call append(9,"#")
    call append(10,"# Description: ")
    call append(11,"#")
    call append(12,"======================================*/")
    call append(13,"");
    echohl WarningMsg | echo "Successful in adding the copyright." | echohl None
endfunction


function AddShellTitle()
    call append(0,"#=========================")
    call append(1,"#")
    call append(2,"# Author: xxx")
    call append(3,"#")
    call append(4,"# Email: xxx")
    call append(5,"#")
    call append(6,"# Last modified: ".strftime("%Y-%m-%d %H:%M"))
    call append(7,"#")
    call append(8,"# Filename: ".expand("%:t"))
    call append(9,"#")
    call append(10,"# Description: ")
    call append(11,"#")
    call append(12,"#========================")
    echohl WarningMsg | echo "Successful in adding the copyright." | echohl None
endfunction

function UpdateTitle()
    normal m'
    execute '/# *Last modified:/s@:.*$@\=strftime(": %Y-%m-%d %H:%M")@'
    normal ''
    normal mk
    execute '/# *Filename:/s@:.*$@\=": ".expand("%:t")@'
    execute "noh"
    normal 'k
    echohl WarningMsg | echo "Successful in updating the copy right." | echohl None
endfunction


function UpdateShellTitle()
    normal m'

    let n=1
    let suff = expand("%:e")
    while n < 10
        let line = getline(n)
        if suff != "sh"
            if line =~ '^\#\s*\S*Last\smodified:\S*.*$'
                call UpdateTitle()
                return
            endif
        else
            if line =~ '^\#\s*\S*Last\smodified:\S*.*$'
                call UpdateShellTitle()
                return
            endif
        endif
        let n = n + 1
    endwhile
    if suff != "sh"
        call AddTitle()

        call AddShellTitle()
    endif
