kandi X-RAY | phobos Summary
Phobos makes use of Blender's hierarchical object graph and its bone objects. These objects, normally used for animating 3D characters, allow to store 3D coordinate systems and apply constraints to their movements, for instance to restrict the movement of an object to a certain range on a specific axis. This allows to replicate the links and joints defined in a URDF model and together with the hierarchical tree of parent and child objects, the complete, branching kinematic chain of a robot can be represented. By attaching meshes or primitives to the bones, Phobos allows to add visual and collision objects to a model. Additional objects allow storing further information, e.g. centers of mass of each part of a robot, thus refining the physical representation. Sensor objects can be added to correctly place and orient devices such as laser scanners, cameras or contact sensors. Making use of Blender's custom object properties, any necessary information can be added to the model, from inertia tensors to opening angles of cameras.

QUESTION
I'm working on a project in the D language and I want to use a module from the standard library called std.sumtype. I'm on debian oldstable, and I've tried both GDC and LDC. DMD is unavailable, because I'm using a machine with an armhf architecture. Neither of these compilers can find std.sumtype, despite it being in the standard library. I also tried downloading 3 different versions of sumtype.d from the phobos repositories of all three D compilers. Each of these would not compile. How can I use this? Am I on the wrong version?
ANSWER
Answered 2022-Jan-13 at 20:49std.sumtype is a pretty new package that was added in 2.097.0: https://dlang.org/changelog/2.097.0.html#std-sumtype so the debian oldstable packages probably don't have it yet as you would need at least:
- DMD 2.097.0
- LDC 1.27.0 (beta.1 or above)
- upcoming GDC in May 2022 (see announcement)
If you want to use the latest compiler you could always download the latest LDC archive and extract it somewhere and run it from there or use the install.sh script from the download page for portable and multiple simultaneous installs.
std.sumtype is an adoption of the dub package sumtype so if you are using dub, you can depend on that as well and not need to get another compiler outside the package manager.

I am trying to write a proxy in wso2 which, given an input in jason format, calls a webservice with a slightly different signature. I wrote a Javascript function to perform the transformation but I get the following error message:

...ANSWER
Answered 2021-Oct-23 at 13:48Well, I've never worked with WSO2 myself, but let's take a look at the error message you're getting. It's this:
TypeError: Cannot call method "info" of undefined (#3) in at line number 3
The error seems clear enough. You're trying to call an info method on something that's undefined, and you can't call methods on undefined.
Let's take a look at line 3 of your script, where the error tells us the problem is:

I get a mysterious error when I compile my code I wrote in dlang it shows
"Unexpected '\n' when converting from type string to type int"

Import std.string and use readln().replace(“\n”, “”); instead of just readln(). That error really isn’t that mysterious.

I don't think there's an interesting case of a random access range without slicing (or vice versa). When we introduced ranges we wanted to be as general as possible, but that turned out to be overengineering.

Description : I am trying to transform from xml to json using script mediator in wso2 3.2 api manager. The issue which I am facing is the script mediator method getPayloadXML() is not able to pull out a specific value from xml where it always returns as ReferenceError: "code" is not defined. I tried multiple things but couldn't figure out how to achieve this. Any help from someone would be really appreciable.

QUESTION
I have a value which is expensive to calculate and can be asked for ahead of time--something like a lazily initiated value whose initialization is actually done at the moment of definition, but in a different thread. My immediate thought was to use parallelism.-Task seems purpose-built for this exact use-case. So, let's put it in a class:
...ANSWER
Answered 2020-Jul-05 at 17:40Templates that take an alias function parameter (such as the Task family) are finicky regarding their actual type, as they can receive any type of function as parameter (including in-place delegates that get inferred themselves). As the actual function that gets called is part of the type itself, you would have to pass it to your custom struct to be able to save the Task directly.
As for the legitimacy of your solution, there is nothing wrong with storing lambdas to interact with complicated (or "hidden") types later.
An alternative is to store a pointer to &t.workForce directly.
Also, in your T val() two threads could enter if(working) at the same time, but I guess due to the atomic store it wouldn't really break anything - anyway, that could be fixed by core.atomic.cas.
QUESTION
I am trying to achieve the following behaviour. On click of a dropdown a tree should get displayed as an option, and whatever operation on the tree, should keep the dropdown open. It should only get closed whenever the dropdown is clicked again and also on outer click.I am using onClick, onClose and onOpen handlers. But somehow onclick and onclose are conflicting. Can someone help me how to achieve this?
