kandi X-RAY | State-Machine Summary
This module allows you to create both single-level and hierarchical finite state machines. State Machines are composed of states, and each state has (optional) callbacks for entering and exiting state. It’s also possible to restrict the transition from states using the from property.

QUESTION
I'm trying to use the PDF document parser called Textricator. It can use 3 different methods for parsing a PDF with some common OCR libraries. (itext5, itext7, pdfbox) The available methods are: text, table and form. Text for normal raw OCR recognition, table to read out structured table data, and form for parsing less structured forms, using a Finite State Machine (FSM).
However, I am not able to use the form parser. Perhaps I simply don't understand how to organize the many configuration states. The documentation is lacking a simple form example, and someone recently posted an attempt to read a very basic table using the form method, but was not able to. I also gave it a shot, but without any success.
Q: Can someone help me configure the state machine in the YML file?
(This is used to parse the demo file from one of that repo's issues, and shown in the copied screenshot below.)
The YML configuration file.
...ANSWER
Answered 2021-May-17 at 18:42As Textricator is kind of a hidden gem for pdf parsing imo, I'm happy to see someone using it and posted a config working with the sample document to the github issue:
QUESTION
aws_stepfunctions_tasks.LambdaInvoke.__init__ takes an input_path argument, which defaults to $ - the entire task input. How can I combine that with the context object ($$), since my Lambda needs information from both? Or do I need to use something else, like the payload argument, to specify more than one input?
ANSWER
Answered 2021-May-13 at 00:03To pass both, the payload and context to lambda function, you will need to wrap the original input inside the another attribute for instance Payload

Stackblitz.com is an excellent resource for creating small experimental projects. However, today I ran into a problem.
I created a stackblitz plain ecmascript project with the following folder structure
...ANSWER
Answered 2021-Apr-19 at 14:36The problem was simple: I accidentally used a template literal for the import path (so: import something from `./somefile.js` ). That can only be a String literal.
Now, the error message did not mention any of that an evidently the linter @Stackblitz does not detect it. Ah well, problem solved. Thanks for your attention and sorry to have bothered you.
QUESTION
So I have been trying to get the grasp for quite some time now but couldn't see the sense in declaring every controller-endpoint as an async method.
Let's look at a GET-Request to visualize the question.
This is my way to go with simple requests, just do the work and send the response.
...ANSWER
Answered 2021-Mar-26 at 13:36If your DB Service class has an async method for getting the user then you should see benefits. As soon as the request goes out to the DB then it is waiting on a network or disk response back from the service at the other end. While it is doing this the thread can be freed up to do other work, such as servicing other requests. As it stands in the non-async version the thread will just block and wait for a response.
With async controller actions you can also get a CancellationToken which will allow you to quit early if the token is signalled because the client at the other end has terminated the connection (but that may not work with all web servers).

I have defined the creation of a StepFunction state machine in Terraform, now I want to set a timer to trigger the state machine everyday, I think probably using cloudwatch event rules is a good choice, I know how to set event rule to trigger a Lambda:

QUESTION
I'm trying to share the SyncBox object between a main state-machine and a sub state-machine. The ideal way is to pass it on the constructor (sub state machine will be a initial state of one of the regions in a more complex case). No matter what, I can't make this code compile and execute properly. Any help?
ANSWER
Answered 2021-Feb-24 at 21:42As far as I can tell you had everything correctly.
The problem, however, is that the substate-list requires all state elements to be default-constructible regardless. (This might not be true for the frontend class, as far as I can tell, but haven't looked all the way into it).
This means that storing a reference as member is off-limits. What I'd suggest instead is storing a pointer.

I'm currently using state-machine-cat to generate dynamic state machine diagrams as SVG images for a reactJS application. This library generates the SVGs as strings, so I am able to integrate them into the react application using
I'm trying to do some "post-processing" of these images in order to add some additional SVG elements and attach onClick event handlers to specific nodes in the SVG.
If this was in plain HTML, I'd do something like the following:

Answered 2021-Feb-24 at 20:56I ended up replacing the
options.replace callback to do processing as it walks down the DOM. It's reasonably fast and lets me do what I need to do.
QUESTION
At work, we start to do the following by lock down the package.json version
...ANSWER
Answered 2021-Feb-16 at 15:03package-lock.json will lock it for developer installations. npm-shrinkwrap.json will lock it for end user installations as well. So, depending on whose dependencies you're trying to pin down, you can use one or the other.
The one case I know of for doing it in package.json is if you only want to pin some of your dependencies but not all of them.
