kandi X-RAY | charlie Summary

charlie is a TypeScript library typically used in Utilities, Interpreter, WebGL applications. charlie has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

This is a slightly updated version of my first Forth VM implementation from 2015, originally written in JavaScript, now updated to TypeScript. Charlie is named in honour of Charles Moore, inventor of Forth. Several parts of the VM and core vocabulary are based on @phaendal's mkforth4-js, which evolved in parallel at roughly the same time span and was highly educational. Other parts are inspired by Factor, Popr and other concatenative languages. The VM & REPL (10KB total) are available online via forth.thi.ng. The project has been online since 2015, but was semi-broken due to CSS layout issues (now fixed).

            Python3 module not found error after installation with pip3
            Asked 2021-Jun-15 at 08:57

            I have been stuck on a module not found error of python3. I have a VM on Microsoft Azure, a Centos 7. Then I installed python3 and pip3, and some packages I needed. But there’s one package that I just couldn’t find after I installed it

            sudo pip3 install --user stockstats

            But whenever i wanted to run a python script using this package, there’s ModuleNotFoundError: No module named 'stockstats'

            What I tried:

            pip3 show stockstats

            As I really want to see where it was installed. It shows nothing. What it is supposed to do is like this:

            for maybe some errors in installing pip.

            • reinstall python.

            • check that the module name is correctly typed

            • install stockstats in pip like "pip install stockstats" (getten from pypi.com)

            Thank You

            Asked 2021-Jun-15 at 00:52

            The situation:

            I am using React in the front-end and a Flask api server. I am wanting to send the data from React to the api and once I have done this I would like to use WTForms to run validations on the data before handling it. The question may seem similar to CSRF Protection with Flask/WTForms and React , but this does not answer the question, please take a look through I have put a lot of effort in writing a good question.

            What I have

            Currently the data is being sent successfully as a json object, where the keys match the names within the wtform structure, the aim is to get wtforms to take that json data and insert it into the object and and handle from there as normal

            How does iterating over HashMaps work in memory: Rust
            Asked 2021-Jun-12 at 21:32

            I know how to iterate over a HashMap in Rust, however, I am a little confused about how this works in memory. How do we iterate over values that are not stored sequentially in memory? A detailed explanation of the code below at the heap and stack level would be much appreciated.

            Answered 2021-Jun-12 at 10:31

            At the end of the intro of the documentation, it is mentioned that the implementation relies on a C++ implementation of SwissTables. This page contains illustrations about two variants: « flat » and « node » based.

            The main difference between these two variants is pointer stability. In the « node » based version, the key-value pairs, once inserted, keep their address in memory even if the hash is reorganised. In the « flat » version, some insertions/removals can make the previous key-value pairs be moved in memory.

            When it comes to the Rust implementation, I am not experienced enough to be certain of any specific detail, but I tried this simple example based on yours.

            Utilizing the package documentation The best I could do was force all columns to the right. It may also depend on your YAML settings. What output are you rendering to? I may have had different results since I am using html_document

            BEFORE:

            AFTER:

            with the package you specify your table body style, and then map it inside your ggtexttable() function.

            tbody.style = tbody_style(hjust=1, x=0.9)

            This is my reproducible solution

            You appear to be using Db2-v11 for Z/OS "DSN11015" in V11 compatibility mode.

            This version lacks the scalar function HASH_SHA256 (and others) which is present in Db2-v12 for z/OS. That is the reason you get sqlcode -440 (no such function HASH...) with your Db2-for-z/os version.

            At Version-11 , IBM documents a function ENCRYPT_TDES which may help you.

            Background information on using this function.

            You can write your own functions if you have the skills.

            You can use the .join string method instead of replace.

            Instead of: stringcodetwo=str(stringcode).replace(" ", "")

            Do: stringcodetwo="".join(stringcode)

            You allocated a SortedList object in main() which allocated memory and never freed it.

            The other blocks belong to the std::string objects inside the list. They are only lost because the list holding them lost track of them.

            When doing your analysis, don't worry about the 6 indirectly lost blocks, focus on the one directly lost one.

            Almost certainly this is a violation of the "Rule of Five". Your SortedList does an allocation in its constructor and doesn't properly manage that allocation in its move-assignment operator.

            Looking at your code in the copy assignment operator, this line is causing the leak

            Haskell - how do I convert piped-in JSON-based to a data record?
            Asked 2021-Jun-08 at 01:17

            I'm building a reinforcement learning library where I'd like to pass certain instance information into the executables via a piped JSON.

            Using aeson's Simplest.hs, I'm able to get the following basic example working as intended. Note that the parameters are sitting in Main.hs as a String params as a placeholder.

            I tried to modify Main.hs so I would pipe the Nim game parameters in from a JSON file via getContents, but am running into the expected [Char] vs. IO String issue. I've tried to read up as much as possible about IO, but can't figure out how to lift my JSON parsing method to deal with IO.

            How would I modify the below so that I can work with piped-in JSON?

            Main.hs

            ANSWER

            Answered 2021-Jun-08 at 01:17

            getContents returns not a String as you apparently expect, but IO String, which is a "program", which, when executed, will produce a String. So when you're trying to parse this program with decode, of course that doesn't work: decode parses a String, it cannot parse a program.

            So how do you execute this program to obtain the String? There are two ways: either you make it part of another program or you call it main and it becomes your entry point.

            In your case, the sensible thing to do would be to make getContent part of your main program. To do that, use the left arrow <-, like this:
