Developing a platform to develop scripts, compile and execute it in the LabVIEW development or run time environment

labview-script-language's Issues

Arithmetic operation not working correctly

variable = 1 - 2 - 6
print(variable)

for the above function we are getting the result as +5, but it has to be -7.

Array Input and Display bugs.

Bug with displaying array.

1. In the VI "D:\TOOLS\LSL\source code\LSL components\data types\Variant to Datatype.vi", data conversion from variant to array types is not handled. please check if the below method of implementation is correct.
   

"Array Constants"

1. How to represent 1D and 2D array constants in the program.

Could it be made available for LV2018?

Could it be made available for LV2018, please?

Abort/Terminate the script compilation or execution

With while loop function and any unexpected issues, the script could run infinitely and there should be a clean option to abort or terminate the scripts.

Comparative operation for Boolean

Since the Comparative Operation like '==' is handled separately for each data type under its corresponding datatypes operation - Bool is not handled

print(True==True)
print(True==False)

Numeric Comparison function

Add functions that make comparison actions on the numeric.

Equal to
Not Equal to
Greater than
Greater than or equal to
Lesser than
Lesser than or equal to

While loop indentation problem

Scenario: consider the while loop code as shown below.

a=0
while(a<10)
->a=a+1
->print(a)

Reason:
the a<10 in while loop will be validated only during Run init core., but it has to executed each time during the loop executes.

So did a similar implementation as Run init core inside Run pre core, and It works well. except for the scenario shown above. because a=a+1 cannot access "a" value which is inside while loop.(due to one intend back)

Create a CHM documentation explaining the basic structure of the sequence

Explain the following,

• Variables and its lifetime
• Indentation and how it works
• Script flow
• data types supported

String concatenation is not working

print("Na"+"vin")

The above syntax is not working, is that removed intentionally?

Create VIP package file for the LSL framework

1. Create a Package for the LSL framework that contains all the components
2. Update the capability to work with factory patterns
3. VIP should install the packages in the user library
4. Drop the example VI's in the proper location

Run the LSL script from Notepad++

Create a hook to Notepad++ that runs the script.

LSL can be created as a EXE or DLL that will be called from the Notepad++ to execute. This will provide a temporary interface for LSL

Array assignment is not working

a=[1,2,3]

When compiling the above command, we are getting a syntax error.

Create CHM documentation for all functions

For every function child that is created and instantiated documentation should be added to the 'Framework Documentation' chm file. the source of the files are present under the documentation folder and the build CHM file placed under source code/support files.

This CHM should be populated from the Main User Interface using a generic API

Modulo Operator Not Working

when running the code, a = 3 % 4, LSL is throwing an error telling invalid syntax. but we have syntax defined as a part of numeric functions.

Please let me know whether "%" cannot be used in LSL.

Integrate the LSL with the LabVIEW Intellisense

https://github.com/analogdevicesinc/LabVIEW-Scripting-UI-Library

LabVIEW intellisense should be independent of the LSL and LSL should feed data to LabVIEW Instellisense to display the suggestions

Python equivalent Scripts

Compare the existing function with the python equivalent scripts using https://www.w3schools.com/python/default.asp

So, all the scripts developed using the LSL will be python compatible and could be used by engineers with their existing Python knowledge

input function to get data from user.

A simple function which can get inputs from the user will be highly helpful.

We can get string data alone, user can further user typecast function to convert the data to appropriate data types.

String operations syntax defining

Please comment your opinion on the below syntax formats and also add if few other functionalities are required.

String functions:

String length.
Syntax: strlen($string$)

Concat string
Syntax: concat($a$,$b$)

Substring
Syntax: substr($string$,$offset$,$length$)

Toupper case
Syntax: toupper($string$)

Tolower case
Syntax: tolower($string$)

Is empty?
Syntax: isempty($string$)

Jump functions

Jump to label
Break out of the loop
continue to start off the loop

Bitwise Operations

Navin, shall we add bitwise operations as a part of numeric operations plugin or shall we create a new function? please find the below image to get different bitwise operations that can be handled.

please comment if you would like to add few more bitwise operations.

Loops & Structures functions

• For Loop
• While Loop
• If, If else, else
• Switch

Create a CHM documentation for simple & complex scripts

Explain all the simple and complex scripts that could be made using the LSL

• Explain the Function inside a function calls
• How to work with functions and variables within a function and its flexibility

Create function definition

Using the indent and available function, the developer should be able to create functions on the script and provide definition to it. Later point this function can be called for execution.

Function definition:

def <function_name>(,,..)
->...
->...

Function execution:

exec <function_name>(,,..)

support for unary operations

we need to add support for unary operations such as

• increment (i++)

• decrement(i--)

the backend has to be updated to support this functionality.
