从 Julia 1.0 中特定目录中的文件导入模块和函数 [英] Import modules and functions from a file in a specific directory in Julia 1.0
问题描述
假设我有一个文件 File.jl 有一个模块 MyModule 包含函数 foo 和 bar 在里面.在与模块文件相同的目录中，我有一个脚本 Script.jl，我想在脚本中使用 MyModule 中的函数.
Let's say I had a file File.jl that had a module MyModule containing the functions foo and bar in it. In the same directory as the module-file, I had a script Script.jl, and I wanted to use the functions in MyModule in the script.
要怎么做呢?
推荐答案
为了找到不在标准 LOAD_PATH 中的模块并能够导入它们，您需要显式更新当前文件夹的 LOAD_PATH 变量
In order to find Modules that are not in the standard LOAD_PATH and be able to import them, you need to update your LOAD_PATH variable for the current folder explicitly
push!( LOAD_PATH, "./" )
然后您将能够适当地导入模块.
then you will be able to import a module appropriately.
请注意，如果文件名为 File.jl 并定义了模块 MyModule，那么您应该导入的是 import MyModule，不是导入文件.在这种情况下，一般建议您使用与定义模块相同的文件名，以避免混淆.
Note that, if the file is called File.jl and defines the module MyModule, what you should be importing is import MyModule, not import File. It is generally recommended you use the same name for the file as for the defined module in this kind of scenario, to avoid confusion.
还请注意，正如上面提到的@crstnbr，您还可以通过简单地包含"文件的内容来简单地将文件的内容转储"到当前会话中；但是请注意，这只是在现场创建模块，因此任何预编译指令等都不会得到尊重.
Also note, As @crstnbr noted above, you can also simply 'dump' the file's contents into the current session by simply 'including' it; note however that this simply creates the module on the spot, so any precompilation directives etc will not be honoured.
