  1. +1 for allowing GitHub as a GPM repo (and GitLab, too). I watched Derek's CLA Summit presentation on What's new in GPM and was intrigued by the local/private repositories! Don't get me wrong, we already share our own libs and might also do so via GPM, but this makes it probably viable to use it for our customer projects. I will definitely have a play with it in the holidays (and am looking forward to it 🙂 )
  2. Yes, I was quite excited about that! But last time I checked, there was no way for private or local repositories. Is that still the case? Thanks for rephrasing. Yes, I think this is what I'm saying.
  3. The second discussion started - again, with Fab - after James' and my presentation on Open Source and Inner Source with LabVIEW. With Github, for example, it seems rather easy to a) publish an open source project and b) contribute to it, once you've learned the very few steps needed to fork a repo and create a pull request. I have no idea how that aligns with what you guys have in mind, but it would be great if there was a way to combine the ease of use of existing platforms with a central repository of LabVIEW code and tools greatness.
  4. The first discussion with Fab, Dani and Jerzy Kocerka was about where to keep the code. We quickly came to the conclusion that it would be great if GCentral did not host their own repositories on their own servers, but rather was able to tap into existing services like Github, Gitlab, Bitbucket and so on. That might also help with acceptance. Personally, I would like to keep our code in our own repos at gitlab.com. We have our readme's, our documentation platform, etc etc. But if there was an easy way to plug into the GCentral website of available code, I'd love to register our offerings (whatever that might be worth!) and see it featured there. And also the other way around: I'd like it if I could find not only properly packaged code from the three main repositories (VIPM, NIPM, GPM) on GCentral, but also other offerings in other formats. We like to keep as many dependencies as possible inside our project directories, so we work a lot with packages that are not installed via a package manager but either extracted/copied into the project directory or maybe sometimes linked as git submodules.
  5. As a community member just wanting to drop my thoughts and ideas for further discussion, I want to give my feedback in a more colloquial way (hence I created this thread).
  6. After discussing with some of the GCentral team and other community members at NIDays Europe in Munich yesterday, I would like to give feedback here so you guys can make of it what you will. Frankly, I didn't really understand that the "User Personas and User Stories" thread is meant for that - I wouldn't have looked into it if Fab had not pointed me towards it. I would like to suggest to rephrase the title of the feedback thread to something that is more easily understood by the majority of people, not only by the top notch of LabVIEW software developers. Moreover, I don't feel comfortable giving user stories for my feedback. That feels to me like phrasing requirements, and at this stage, I only have vague ideas. If those undeveloped musings are not of interest to you, then just ignore this 🙂
  7. To ensure NIER collects the most useful information, you need to set a few INI keys on the process that is executing the LabVIEW code (Development System: LabVIEW.ini in the LabVIEW directory; Run-Time Engine: in a [LVRT] section within the .ini file next to the executable). INI keys: NIERDumpType=full LVdebugKeys=True DWarnDialog=True DPrintfLogging=True promoteDWarnInternals=True Of these keys, you should always set the NIERDumpType=full key when debugging an issue, because this key will cause a larger crash dump with more debugging information to be created. The other INI keys can be used to gather more information, but they have the caveat that they will slow execution of the code down, which can be a problem for certain types of issues. It is also important to note that when NIER creates a full crash dump, it should not be submitted to NI through the NIER crash dialog. The NI system is not prepared to handle crash dumps as large as those generated by NIER with the INI key enabled. (I got this information from an NI support person long time ago, I'm not really sure if all of this still applies. But perhaps it helps?)
  8. I've been using ADO.NET in the last years for Windows applications, and the NI DCT before that. I did one project on RT with the MySQL TCP connector, but as mentioned by @smithd it was difficult getting it to perform well enough. Recently, I've been working with SQLite (with your toolkit as well as directly using the DLL). Next will be to try and get SQLite running on real-time, on linux first, then Phar Lap and perhaps VxWorks - again like @smithd ;-)
  9. I'm using git, but all of my customers who go with SVN use the Tortoise SVN client and are happy with it.
  10. Good point, Shaun. In fact, SingleBoard-RIOs made me think about generating a readme file, so that I could easily find out about the version of the application when connecting only via FTP.
  11. I agree with everything you write, hoovah. But ;-) Customers tend to copy directories and store and reuse projects from time to time. I don't see any reliable way to clearly identify one VI outside of version control other than writing some kind of identifier or history to the VI (be it block diagram, VI properties, front panel, whatever).
  12. I agree that the version information should be (at least also) stored in the .exe file properties, that's what I do as well. But: There is a good reason to store version info on the block diagram. Everybody can identify the version of the VI itself, not the executable, even if it's not under version control any more. I do have customers that don't use their own version control system, and I have no internet access to use mine. So, what I ended up with, is generating an .exe with my build script at the end of the work day, writing the version info also to the readme textfile (which might or might not get lost down the road) and to the block diagram of the main VI. Then I copy everything, take it home with me, and put it in my own version control system.
  13. I create tags for each build. That way, I have "names" for my releases, like for example "v1.2.3". You can easily automate the creation and publishing of tags from within a pre-build VI or a build script. This might help you with naming your installers? I also used to modify the source of a VI to store version information, and sometimes still do (it's an optional part of my build script now). What I like better, and what I do more often now, is create a text file which contains all sorts of information (kind of a readme file for the application). When run from an .exe, I read the version information from the .exe file properties and additional information from the readme file. When running the application from the development environment, I read version information only from this readme file. For libraries, I write the version information (the tag name) to the VI description, so that every VI can still be identified after release. PS: For my older projects, I do just as Thomas suggested: Modify the VI before executing the build spec, then revert afterwards.
  14. True that. Even before LV2014 and this very handy VI... It was the fact that you can't modify the version from the pre-build VI that made me look into automating the whole process.
  15. No need to get jealous. The whole process only works on some of my projects. With our own framework and reuse libraries, there's still some manual work involved, but it gets better all the time... I'm not ready yet to just share the whole code, but you can definitely PM me if you have any specific questions.
