nipm-api-labview

NI Package Manager API (Beta) for LabVIEW 2014 or later.

Overview

My goal is to provide users with a beta API for NI Package Manager tasks. Please feel free to use this API, give feedback, and contribute. NI will use this feedback to create an official NIPM API in the future.

You can use this API to:

Install/uninstall/upgrade packages
Get package attributes
Create feeds, add packages to feeds, remove packages from feeds, list packages in feeds
Register/unregister feeds
...

You can find content, tutorials, and additional tools for NI package management at bit.ly/nipkg

How to Install

Prerequisites:

LabVIEW 2014 or later
NI Package Manager 17.5 or later
Operating System: Refer to the OS requirements for NI Package Manager

Installation Instructions

From LabVIEW, launch Tools»VI Package Manager, search for "NIPM API", and install it.
In LabVIEW, access the NIPM API by going to the Functions Palette»Addons»NIPM API.
(Optional) Install the NIPM Feed Manager (Beta), and use it to manage NIPM feeds and packages.

Note: If necessary, you can find historical versions in the Exports folder.

Documentation

Refer to the Context Help and examples that ship with the installed API.

Support

This API is not officially supported by National Instruments. You can use this GitHub repository to find the source code, report issues, and contribute.

Source Code

Source folder - Contains the source code for this API. At a low-level, this API calls the nipkg command-line interface (CLI).
Build Spec folder - Contains the VIPM build spec (.vipb) used to create the .vip file.
Export folder - Contains versions of the VIPM package (.vip), which you can use to install this API.

nipm-api-labview's Issues

Need functions to be made reentrant to facilitate parallelizing For Loops

Please make all API VIs reentrant.

UNC Package Destination Folderpath - Error

I am using a feed located on a share with UNC notation (e.g. \servername\folder...).

When the application NIPM Feed Manager is started, it reads the file Feeds.ini.
Here is the problem:
The first Read String.vi has the Boolean read raw string? set to true and the second one not.

This result in a wrong interpretation of the server name (\servername instead of \\servername).

I set the Boolean read raw string to true for the second Read String.vi and everything is ok.

Have a nice day.

Packing a package results in Error -125043: "Attribute name 'Package' does not exist."

NIPM_API.lvlib:Pack.vi always returns error -125043.

This occurs even when using the provided example [Advanced] Modify an Existing Package File (Unpack Modify Pack).vi and unpacking then repacking a package with no changes.

Possible reason(s):

Error -125043: Attribute name 'Package' does not exist.

Complete call chain:
     NIPM_API.lvlib:Call NIPKG CLI.vi
     NIPM_API.lvlib:Pack.vi
     [Advanced] Modify an Existing Package File (Unpack Modify Pack).vi

I am using version 3.2.1.9 which was distributed on VIPM. I uninstalled and reinstalled the library to confirm the bug.

Please make "Call NIPKG CLI" public.

"vi.lib\National Instruments\NIPM API (Beta)_support\Call NIPKG CLI.vi" is a very useful function. I'm not sure why this is private. Since this API doesn't expose all functions available via the command line I need to invoke this function in my code so I have access to the full command line api offered by NIPM.

Need a timeout input on "Call NIPKG CLI (runas admin).vi"

In "\vi.lib\National Instruments\NIPM API (Beta)_support\Call NIPKG CLI (runas admin).vi" there is a while loop that polls to see if nipkg.exe has completed its execution. It polls once every half second. However it runs the risk of hanging without a timeout. The user should be able to specify a timeout.

Also, there may be an alternative to the polling method to determine if installation is complete. In "https://forums.ni.com/t5/LabVIEW/SysExec-cmd-Run-as-administrator/m-p/3941031/highlight/true?profile.language=en#M1120633" rolf says that an alternative to shellExecuteA is ShellExecuteExA. But it has a complex input struct which is hard to program in LabVIEW. (https://docs.microsoft.com/en-us/windows/win32/api/shellapi/nf-shellapi-shellexecuteexa)

Please create a function that returns information about a package given it's path.

A handful of the API functions require package name and version as inputs. It would be helpful if I could provide a function a path to an nipkg and have the name, version, and architecture returned.

Need "Get Package Attributes" to have ability to return all dependencies, not just immediate dependencies.

It would be helpful to have this function take an input to determine if dependencies return the list of dependencies recursively. Or perhapse a seperate function that returns a list of dependencies recursively. Even better would be the ability to filter the results on things like Feed(s), and "shipped from NI or not", ect.

Add get-dependencies

We are missing VI that corresponds to the get-dependencies NIPM CLI call. We should add that functionality.
