Julia readuntil用法及代码示例

readuntil(stream::IO, delim; keep::Bool = false)
readuntil(filename::AbstractString, delim; keep::Bool = false)

从 I/O 流或文件中读取字符串，直到给定的分隔符。分隔符可以是 UInt8 、 AbstractChar 、字符串或向量。关键字参数 keep 控制分隔符是否包含在结果中。假定文本以 UTF-8 编码。

例子

julia> open("my_file.txt", "w") do io
           write(io, "JuliaLang is a GitHub organization.\nIt has many members.\n");
       end

julia> readuntil("my_file.txt", 'L')
"Julia"

julia> readuntil("my_file.txt", '.', keep = true)
"JuliaLang is a GitHub organization."

julia> rm("my_file.txt")
