Wolfram: Load a Package or File

Get (Load a File of Wolfram Code)

Get[filename]

🔸 SHORT SYNTAX: <<filename

• Load a file of Wolfram language code, by file name.
• filename can also be file fullpath.
• If filename is not fullpath, search the file in $Path. 〔see Wolfram: Search Paths $Path〕

• Get

Get[ "PlaneCurvePlot.wl" ]

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

Example. Load File in Current Notebook Dir

(* load a file that is in the current notebook dir *)

Get[FileNameJoin[ {NotebookDirectory[], "myfile.wl"}] ]

Example. Load File in Current Script Dir

(* load a file that is in the same dir as the running script *)
Get[FileNameJoin[ {DirectoryName[ $InputFileName ] , "myfile.wl"]}]

• Wolfram: Get Script Path, Notebook Dir

Load a Package by Context Name

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.

• Wolfram: 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.

• Wolfram: Init Dir, Library Dir

• Needs

Needs[ "PlaneCurvePlot`" ]
