evalfile
evalfile(path::AbstractString)
Load the file using include, evaluate all expressions, and return the value of the last one.
Examples
In the Julia programming language, the evalfile(path::AbstractString) function is used to load a file using include, evaluate all expressions in the file, and return the value of the last expression.
Example 1: Evaluate a file and return the value of the last expression
julia> evalfile("script.jl")
42In this example, the evalfile function loads the file named "script.jl" using the include function, evaluates all expressions in the file, and returns the value of the last expression, which is 42.
Example 2: Use the returned value for further computation
julia> result = evalfile("computation.jl")
137
julia> result + 5
142Here, the evalfile function loads the file "computation.jl", evaluates all expressions, and returns the value 137. You can assign this value to a variable (result) and use it for further computations.
Common mistake example:
julia> result = evalfile("script.jl")
ERROR: LoadError: MethodError: no method matching evalfile(::String)In this example, the error occurs because the evalfile function is not a built-in Julia function. Please ensure that you have defined the evalfile function or are using a package that provides it.
It's important to note that the evalfile function uses include internally and evaluates all expressions in the loaded file. Exercise caution when using this function with untrusted files, as it can execute arbitrary code.
