kandi X-RAY | crab Summary

crab is a C++ library typically used in Code Quality, Code Analyzer applications. crab has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Crab (CoRnucopia of ABstractions) is a C++ library for building program static analyses based on Abstract Interpretation. Crab does not analyze directly a mainstream programming language such as C/C++ or Java but instead it analyzes its own CFG-based intermediate representation (CrabIR). This allows building analyses for different programming languages assuming a translator to CrabIR is available. In spite of its simple design, CrabIR is rich enough to represent languages such as LLVM bitcode.

            The dialog you are trying to interact with is a native OS dialog, it's not a kind of browser handler / dialog / tab etc. So Selenium can not indicate it and can not handle it. There are several approaches to work with such OS native dialogs. I do not want to copy - paste existing solutions. You can try for example this solution. It is highly detailed and looks good.

            How to sort data into new columns based on information in other columns
            Asked 2022-Feb-05 at 23:41

            I have data on fiddler crabs that includes which of its claws are dominate (L or R) (listed as handedness), and the length of specific walking legs (the merus) on each side, which are again sorted by L and R.

            Merus_L Merus_R Handedness 13.300 10.950 R 9.980 12.250 L 8.750 12.150 L

            What I want is to have a column (or a way) to sort these merus values by whether they were on the same side as the major claw (aka dominate claw). for example, if you go back to the above table, the first crab is right handed, so I would like the Merus_R data to be listed under a column called "Major_merus", and the data from Merus_L to be listed under "Minor_merus". the correct sorting is shown below:

            Major_merus Minor_merus Handedness 10.950 13.300 R 9.980 12.250 L 8.750 12.150 L

            I've already tried the ifelse command recommended by my professor, but I don't know how to use the new data, or why only the Major_merus is correct now.

            I modified the solution, I guess this one is more straight forward:

            • For Major_mercus column, I first created a customized name with paste0 by concatenating Merus_ with the value of Handedness in every row. Then I retrieve the value with get function
            • For Minor_mercus I basically did the same but I used ifelse to first swap the R and L value in each row and then retrieve the desired value

            Pandas read_* methods always prevent duplicated columns names, because is problem with selecting.

            If use df[0] it select both columns, not one.

            I have a function that transforms a dataframe's structure (making each value for "year_season" factor as its own column) for each value in a list (a list of species names) and reorders the 1st column values (the location or "site") to be in order (low to high). I then tell it to save the dataframe as a matrix and print each matrix as a csv. For some reason though, the function is making a another column out of the rownames and I can't remove it.

            ANSWER

            Answered 2021-Nov-08 at 10:16
            The Problem

            the problem is not with your useEffect hook, it's working properly and called once at component did mount. the problem is with the setSubtotal((prev) => prev + +item.price); in your return method.

            Every change on state variables will cause re-rendering, with every re-render your order.map will be recreated. so changing the state during order.map will cause re-render and the re-render cause the order.map to draw again. It's the cause of your infinity re-render.

            Note: you can simply comment the setState inside of your map function to stop this behavior.

            The Solution

            There are some options to control this situation like using useRef for subtotal to prevent the cause of re-rendering.

            Also, you can calculate your subtotal inside of your useEffect hook before calculation of totalAmount and setting it.

            Embedding CLIPS into C++ application - interacting with CLIPS from C++
            Asked 2021-Oct-14 at 20:09

            I have compiled CLIPS 6.4 into a shared library (compiled as C++) so that I can use in a C++ application.

            I want to now write a simple test C++ application that allows me to:

            1. Start up the CLIPS engine
            2. Load a CLIPS program (see animal.clp)
            3. Assert a fact from the C++ program to the CLIPS engine and receive responses back from CLIPS in my C++ program
            4. Safely terminate the CLIPS engine and cleanup when nothing on the agenda (all rules fired) - i.e. program completed
            Testapp.cc ...

            ANSWER

            Answered 2021-Oct-14 at 20:09

            The CLIPS Advanced Programming Guide is here: http://clipsrules.sourceforge.net/documentation/v640/apg.pdf

            You can use the Load function (section 3.2.2) to load a file. There is an example of its use in section 3.6.1.

            You can use the GetNextActivation function (section 12.7.1) to determine if the agenda has any activations.

            The simplest way to create facts is using the AssertString function (section 3.3.1). Sections 3.6.2, 4.5.4, and 5.3 have an example use of this function. You can also use the FactBuilder functions described in section 7.1 (with an example in section 7.6.1).

            If the results of your program running are represented by facts, you can use the fact query functions via the Eval function to retrieve those values from your program. Section 4.5.4 has an example.
