I have created a notebook, with functions. The only thing that I want to change in the notebook later is the input file. I therefor want to have a button that runs every input step-by-step so that I do not have to go into every input and press enter for it to update. How could this be done.

Perhaps the simplest thing is to command-A and enter, which selects all the cells and evaluates. Or you can use a button

evalStart := Module[{}, 
    FrontEndExecute[FrontEndToken[InputNotebook[], "EvaluateInitialization"]];
    FrontEndExecute[FrontEndToken[InputNotebook[], "SelectAll"]];
    FrontEndExecute[FrontEndToken[InputNotebook[], "EvaluateCells"]];];
Button["do it", evalStart]

When you evaluate this, a button appears. Every time you press the button, it evaluates everything by first evaluating the initialization cells (if any), then selecting all, then evaluating all the cells.

    $\begingroup$ Why not to simply use the FrontEndExecute[FrontEndToken[InputNotebook[], "EvaluateNotebook"]]? Anyway, good solution! $\endgroup$

There is a Evaluation -> Evaluate Notebook menu for that.

Or, you can set some cells to have Initialization property (documentation on usage).

  • $\begingroup$ Since he/she asked for a button, the other answer is "better" but you are totally right: There's a simple menu function for that. $\endgroup$
