Are there any documents/samples to use Script in LEAP (Like WEAP)?

I read the description of functions in Script Editor (In LEAP), but I could not find the function to select the type of final results.

Also, how can I select/deselect different fuels for a result (Using API)?

In addition, when I want to use ReadFromFile in Script, it always omitted "/" from the FileName; so shows the following error to me. the actual path which I use in Script is

LEAP.Branch("Demand\\Household\\Urban").Variable("Activity Level").Expression = "ReadFromFile(D:/New Folder/Input.csv)";

(I am running Script outside of LEAP)

Thanks

This question is best answered in the context of a particular script or problem that you're trying to solve. Which result are you trying to use in your script, and how are you currently trying to extract this result using the API?

To your other question (the removal of slash delimiters from your file path), be sure to use Windows-style path names, which use a backslash "\" between directories. These should also be used to reference LEAP branches within your Branch() method. In other words, try:

Let me know if this works,

Taylor

I do not understand "This question is best answered in the context of a particular script or problem that you're trying to solve.". Could you please refer me to that context?

About the ReadFromFile, I used different formats.

Error = Branches,Item: No branch found named "DemandHouseholdUrban" {Error1 in Attachment.}

Using the following formats:

Error = Files "d:new folderinput.csv" not found in ReadFromFile {Error2 in Attachment.}

It is good to mention that I am writing in JScript (Not VBScript). Does it matter?

Are you trying to manipulate the LEAP Results GUI using the API as you would with your mouse, or are you trying to generate a set of results before (for example) printing them to another file?

Regarding the error(s) that you've been seeing, without a complete working example I can only speculate. But I think they are being introduced by the interpreter, and not by LEAP or API. I am not very familiar with JScript myself, but do I think that backslashes will need to be escaped properly. Do you see your 'Error 2' for each one of the four ReadFromFile formats that you tried? To help debug, I'd suggest that before trying to pass the expression into LEAP through the API, first ensure that it is correctly being interpreted by JScript as a string.

Hope this helps,

Taylor

The following code is my JScript. Different formats that I tested are commented in the code. None of the works to assign ReadFromFile to Expression of a variable. (I see 'Error 2' for each one of the four ReadFromFile formats that you tried)

I'm able to reproduce your problem by entering the ReadFromFile() function when typed directly into a LEAP expression, without using the API. So I think the problem lies in that function - we'll investigate it, and hopefully have a solution for an upcoming version of LEAP.

In the meantime, can you accomplish what you want to do using the ReadFromExcel() function, to read from an MS Excel file?

Taylor

No, it is not necessary. The ReadFromExcel() function takes an Excel range, which contains information about which worksheet the data are found within.
