QUESTION
I'm making a React component library to abstract out some components I use in multiple projects. Some projects are made with CRA, some with Gatsby, some might be something else, etc. I used the Neutrino.js framework/toolchain as it was linked on the React docs site, but the issue I ran into is that by default the output files of the build all use the window object, which causes gatsby build to break as window doesn't exist in Node/SSR. Is there a way to make Neutrino/webpack output a bundle that doesn't use window? While searching for a solution and comparing to other libraries it seems that ESM is the best but I'm not sure how to get webpack to use it, I think it's currently not supported. Is there another tool I should be using for this?

I originally followed this project to add Firebase to a Gatsby React app. It involves making a Firebase context, wrapping a root layout with a provider, and then using a withFirebase HOC to wrap components with a Firebase consumer as needed. When I originally did it, it worked fine, but I wanted to move the code into a package I could reuse among my apps. Here's the HOC
...ANSWER
Answered 2020-Aug-05 at 17:14I heard from a clever friend of mine that the problem is because React contexts are defined at the module-level, and so since you tried to have your contexts in separate entrypoints, things will not go so well.
I think you can try making an index.js file that re-imports and exports everything, and then things should work as it's all consolidated in one module.
QUESTION
In this page the CheerpJ conversion of the applet in this page (with identical byte-code) does not seem to recognize mouse dragging past the applet frame boundary. It would be nice if that were possible.
Is this just a problem with my client-side setup (Linux Debian 9.2), or do others see the same behvior?
What is very strange, is that the original behavior is converted correctly on the not-supported-by-CheerpJ iphone browsers (I have checked safari and firefox there). Could investigation of this fact help CheerpJ developers understand how to make the MouseMotionListener interface recognize mouse dragging anywhere on the screen, not just within the applet frame?
Maybe this is impossible, but I thought it was worth asking.
Edit: Changed title to be less negative about CheerpJ (which overall I find almost too cool to be true!) and more reflective of actual the question.
...ANSWER
Answered 2020-Jul-25 at 08:46The mouseDragged method is correctly implemented to the best of our understanding. The Java event is derived from the mousemove JavaScript event which is not delivered when the mouse is outside of the applet surface. With the legacy plugin applets are displayed on native windows which have different behavior.
It could be possible that using different JavaScript events, like mousedrag would make CheerpJ behavior more similar to native, but reworking this without causing regressions would require significant work and it is not currently a priority for us. Especially considering that our customers normally have full screen Swing applets which cannot exhibit the problem
On mobile devices the touchmove event is used, which is probably what causes the difference you see.

QUESTION
I began a very helpful discussion with Alessandro Pignotti (@alexp-sssup) on https://gitter.im/leaningtech/cheerpj?at=5f189bf76279c91f420801af
about how to get Java applet byte-code to work with CherrpJ in present-day browsers.
Hopefully the two examples referenced there in this post can serve as a guide to others who might also be struggling with getting the basics of java applet conversion with CheerpJ going.
As I mentioned there I would, I am now putting this follow-up question in stackoverflow:
I was hoping to get this page to work in which I am trying to run the same byte-code with both the and tags on the same page. However the page never loads properly. The best I can achieve is (with page loading seeming to hang) to force some hung script to stop, which then often ends up bringing the CheerjP button up, but I have yet to the get button in the original applet to show on the same page (in a java-enabled browser-setup where the legacy applet does work properly from this page). Sometimes the browser completely hangs before even the Cheerpj script gets to work.
So my question is: Is what I am attempting even possible, and if so what could be wrong with this first attempt of mine?
P.S.: The stackoverflow tag [cheerpj] does not exist, so the suggestion on Gitter to use it fails for me: I don't have a reputation of 1500 :( !!! Since a pretty thorough web search has revealed very little in-depth technical discussion about CheerpJ besides what's in the Gitter CheerpJ room I reference at the start of this post, I am not sure how far the attempt to move discussion in to stackoverflow is going to go.
...ANSWER
Answered 2020-Jul-24 at 10:17What you are trying to achieve is not supported by CheerpJ. When CheerpJ starts it will automatically replace any We don't plan to support this use case in the future since for the vast majority of users the native Java plugin does not work anymore anyway. You may consider using two , or tag containing Java applets and execute them internally. The special prefixed tags, such as are designed to avoid accidental execution by the native plugin if installed.
</code> tags to get the behavior you want using 2 independent pages.</p>
QUESTION
I have a project under QNX. I am trying to do unit-test (gtest) on it and I'm confronting with the following problem:
In one of my source files I use the sigevent structure from sys/siginfo.h (https://www.qnx.com/developers/docs/6.4.1/neutrino/lib_ref/s/sigevent.html).
In my unit-test I have created a stub file for the sys/siginfo.h file where I stubbed the sigevent structure but it complains of redefinition because there is also a sigevent struct under linux in https://sites.uclouvain.be/SystInfo/usr/include/bits/siginfo.h.html.
The two stubs have different structure - I cannot use one instead of the other. I cannot use namespaces because the sigevent struct is used in my source file and not in a stub file from unit-test - I'm not allowed to change the source file.
If I were to be able to change the source file, It would also have been impossible to fix this with namespaces since sys/siginfo.h is not a user-defined header. I think a solution would be a wrapper on sys/siginfo.h from QNX.
But how can solve this from unit-test?
Errors:
/stubs/sys/siginfo.h:166:8: error: redefinition of 'struct sigevent' struct sigevent {
/usr/include/x86_64-linux-gnu/bits/siginfo.h:320:16: error: previous definition of 'struct sigevent' typedef struct sigevent
P.S.: I tagged "C programming" for this issue because it's not entirely unit-test.
Thanks, Carmen

Answered 2020-Jun-09 at 09:16This answer is only tentative but it is too long for a comment.
The situation is: You have a piece of software you want to test which is designed to run under QNX, on some embedded device. It uses struct sigevent whose actual definition is system dependent. You have written a mock mimicking QNX's version of it, for test purposes and in order to be system independent.
Now you write a module test in a software environment under Linux.
My first question is how you prevent duplicate definitions of struct sigevent when you eventually compile your program under QNX (I assume you are not cross-compiling under Linux). Preventing this should be similar to preventing it under Linux. (If you actually are cross-compiling you need to fix that cross-compiling environment; it should come with its own system library catering to QNX and not by default include Linux headers.)
Linux comes with its own struct sigevent which now collides with yours. I assume that the structure definition is included indirectly by e.g. signal.h, a header which, I assume, you need. (You should perhaps first find out whether you really need the offensive header at all; maybe you have superfluous includes in your file.)
The easiest case is if the struct definition comes in its own header, which then has its own include guard, e.g. https://code.woboq.org/userspace/glibc/sysdeps/unix/sysv/linux/bits/types/sigevent_t.h.html.
You would simply define __sigevent_t_defined on top of your source file, which would be transitively visible in all included headers and prevent inclusion of that header file (and thus a redefinition of struct sigevent):

the part of input file concerned is :
...ANSWER
Answered 2019-Dec-06 at 19:43If the user provides a value in the ini file, the function Ini%Read_Logical returns what that value is interpreted to be as a LOGICAL. If the user provides no value, the function Ini%Read_Logicalreturns the value of the default argument (the second actual argument in the references to the procedure binding).
You provide a value of "F in the ini file, which is interpreted as .FALSE. ("F" is the first letter of "False"), so Ini%Read_Logical returns .FALSE.. The value of the default argument is not used.
.FALSE. .EQV. .FALSE. is true, so the code executes the block of statements immediately following the if statement.
The type of the value returned by Ini%Read_Logical is LOGICAL. To compare logical values you use the .EQV. operator (short for "logical equivalence"), or .NEQV. ("not equivalent"). The == and /= intrinsic operators used for the numeric and character types are not defined.
