kandi X-RAY | ohm Summary
Ohm is a parsing toolkit consisting of a library and a domain-specific language. You can use it to parse custom file formats or quickly build parsers, interpreters, and compilers for programming languages. The Ohm language is based on parsing expression grammars (PEGs), which are a formal way of describing syntax, similar to regular expressions and context-free grammars. The Ohm library provides a JavaScript interface for creating parsers, interpreters, and more from the grammars you write.

QUESTION
Im trying to use the GlobalPlatform library from Karsten Ohme (kaoh) in Delphi. Thanks to the help of some people here on stackoverflow i got it parially working and i am able to setup a connection to the cardreader. Now i am trying to select an AID, and therefore i need to pass the AID as array of Bytes to the function.
I use the GPShell (the commandline tool that uses the same library) source code as a reference to help me translate the functions. There i found the convertStringToByteArray function, which takes a string and converts it to a array of Bytes.
The original C++ function:
...ANSWER
Answered 2022-Apr-09 at 22:28The original C++ code parses pairs of hex digits into bytes:
A000000003000000 -> A0 00 00 00 03 00 00 00
But your Delphi code is parsing individual hex digits into bytes instead:
A000000003000000 -> A 0 0 0 0 0 0 0 0 3 0 0 0 0 0 0
Try this instead:
QUESTION
I want to use the GlobalPlatform.dll from kaoh Karsten Ohme in Delphi. So i tried to translate the headers so i can use the GlobalPlatform.dll in Delphi.
The first i translated was Connection.h, i uploaded it on pastebin here.
The second i translated was Security.h i uploaded it on pastebin here.
First i establish a context with the OPGP_establish_context function, that seems to go alright because the result is a OPGP_ERROR_STATUS_SUCCESS and the message also states "success".
But then i try to list the readers with the OPGP_list_readers function, which also returns a success - but when i try to read the returned names i get various access violations (mostly at adress 00000000 and trying to read 00000000, but there are variations between my tries).
My code is assigned to a button click:

Image Here I apologize if my photo is not clear as i don't have time for software drawing, and i didnt use a breadboard as actually the DF Player is slightly bigger than the holes. The Arduino Pins Used is 11,10 and 5V and 2 Pins for the GND Here is the Code of the DFRobot Library used as is . The Files on the SD Card are in a folder mp3 and written as 0001.mp3 0002.mp3 ..etc When i Connect and try it out .

I have a spatial grid of dimension 72 col × 24 rows. For this question, I tried to create a small polygon grid (3×3) which I hope you can run in your PC too.
As you can see it is a 3×3 grid, however the numbering of the grid cell starts from bottom left of the last row towards bottom right & again continues from left side of the middle row towards right.

I have defined this method to read from JSON-Files, but it doesnt work with multiple results. Can I modify this code read out every result in the given Array?
The Input: (phase = Split of name, e.g "Test01" from "01_Test01_Version1.json", testReport = deepcopy of Json-file )
ANSWER
Answered 2022-Feb-16 at 16:04Don't know exactly what you would like to achieve so can not write down the code for you. But so far, I can see there's a problem in the code you wrote:
measurement['RESULTS'][param]['UNIT']
The param is the name of the measurement. You need another iteration in the results array.
I assumed that you would like to retrieve the last measurement item only then we could do:

There are no helpful class-names in the HTML. Sample here:
...ANSWER
Answered 2022-Jan-05 at 21:31At a glance, your selectors seem fine. The problem appears to be that the elements are rendered but without data, so you're scraping the empty text contents without waiting for them to be filled in asynchronously.
I tried using a waitForFunction that polls on whether the text contents you want are empty. When they're not empty, then go ahead and scrape:

I would like to use my Raspberry Pi as a weather station. Therefore I bought a "Debo Sen Rain" and a "Debo Sens BME680". Because I've never worked with Python before, I copied two scripts out of the Internet. They do both work very well. Yesterday I created a telegram bot, which should send me the current measured data, when sending "/data" or "/rain". So I copied the original scripts in a new python script and embedded the bot. Unfortunately, It doesn't work but I can't locate the error.

Need help in React…I converted the complex xml file into js object format. After converting the xml file, the js object are stored in ress variable that is showing in the picture. We are storing the different partial transcript in different variables. Is there any way to do it using loop and split it with regular expression in each iteration. So it would he easy for me to use map method instead of calling the component again and again for each partial transcript.
