WolframLang: Load a Package or File

Load Any File of WolframLang Code

• Get[filename]
• Get[fullpath]

Load a file. It search file in dirs in $Path.

• Get

Get[ "c:/Users/xah/Desktop/Xah_WolframLang_packages/PlaneCurvePlot/PlaneCurvePlot.wl" ]

Load File in Current Dir

(* load a file, where the file is in the same dir as the current notebook *)

Get[StringJoin[NotebookDirectory[], "myfile.wl"]]

(* load a file, where the file is in the same dir as the running script *)

Get[StringJoin[ DirectoryName[ $InputFileName ] , "myfile.wl"]]

[see WolframLang: Get Script Path, Notebook Dir]

Load a Package by Context Name

Another way to load a package, is to call Needs. This is a slightly higher level, based on Context Name , not a hard file path. It'll only load the file if the context is not already loaded.

Needs[ ContextName ]

Load a file if ContextName is not already in $Packages

The file name to load is based on ContextName to filename convention. You can give a second argument for a specific file name.

[see WolframLang: Context (Namespace)]

Once it figured out a file name, it calls Get to load the file.

in general, for Needs to work, you should put packages in the Wolfram Library Dir, in the Applications or Autoload subdirectory. [see WolframLang: Init Dir, Library Dir]
