So I am working on a set of very simple tasks which widely use stringr. One task is to remove a specific pattern from a string.
Below is a toy sample which contains columns
current_house. I want to remove the pattern given in
temp and create a new column, say
temp2. For a few observations, it seems that
str_remove() does not work. I already tried with
str_remove_all() without success.
What am I missing? It should not be a problem related to the number of tokens in the search pattern as it successfully removes multi-words patterns....

The parens in your
current_house are being interpreted as regex groups. Use
stringr::fixed to fix that:
I've made a
JTextArea where I input different commands and separate them by newline
"\n", and if there is an error in one of the lines then I write it in a console output. Here I made a very simple, and not the best solution to make this line indication, but it's a bit buggy.
How I made it
I've defined a
textArea where I can type different information/commands, and if one of the commands/lines is invalid I write it in the console just to display something for now. I basically count the lines by splitting the
textArea rows up by
"\n" and then count which line the error occurs in, and the left
consoleLineNum is using the amount of rows in
textArea, to then make a string containing all the numbers of
But here my question is, is this a good enough way? If so, why/how can I make it more robust? Or how can I make this indication with line numbers, in the left? It has to increase each time the user makes a new line in the

I'm working on creating a Bazel extension for Haxe and while I've had some initial success in getting things to build, I've hit a roadblock and I'm not sure what the right way around it is.
In Haxe if you declare a dependency on a Haxelib in your build.hxml file, when you perform the build the Haxe compiler will go grab that Haxelib from the internet and install it locally if you don't already have it, using a program named "haxelib". It seems that this process is being blocked by the Bazel sandbox, but I haven't been able to find much documentation on how the sandboxing works, if this is expected, and if there's a way around it. I'm currently working in Windows 10; this is the error that I'm getting:...

The particular error that I was getting -
Unix error 21 - was caused by the shell that Bazel creates not having the COMSPEC environment variable: see here and here for more details. Adding that variable to the environment via the
--action_env=COMSPEC command line got me past that error. However the command shell that gets spawned by the Haxe process cannot handle symlinks, and so has a lot of trouble trying to access the directories brought in by Bazel, so I think using haxe via this route will end up being a lost cause. Just for the record though, I was able to get the haxelib command itself to run through the haxe process, so the answer for this question is to ensure the COMSPEC variable is set.
From a data frame like this...

I think this does what you're trying to do, although I am still not entirely sure if I understand it correctly.
I am building a GUI Python code using tkinter. I have a CSTR model that is solved inside a for loop; the values are updated inside the for loop. I have four parameters that are being updated T,Ca,Tc,q. I am using the TopLevel() to display the results in EVERY iteration inside for loop. In other words, I want the results at each iteration to be shown once the results are out on a display, and once I am in another interation, I want to open a new window file again and update the values with the new calculated values in the for loop. I have used the destroy function using the same time of the iterations in the for loop.
Kindly find my code attached below ( I have attached part of the code only for simplicity):...

In a GUI, your code is basically a guest in the GUI toolkit's event loop (
mainloop in tkinter).
So you cannot have a long-running loop in a GUI program; you have to structure your code differently. For example, say that you have a loop like this;
I'm right now writing a code for my coursework that analyzes a manually inserted text. I'm supposed to find the total number of non-space characters, and total words. Also, I'm supposed to find any repeated words in the string, then display them with the number of repetitions. I'm stuck in finding repeated words and displaying the number of repetitions. Also, my knowledge to C is limited, with the topics I know including pointers, strings, files, and functions, loops, if conditions, etc... Below is my code so far:...

According to what I've read in comments you already solved first two points so i'm going to focus mainly on repetitions.
To do it you can use Trie data structure, please take a look at below link.
it's in C++ but not so many things from C++ are really used so it can be easily rewrite to C. You need to add only a few lines to GeeksForGeeks code to make it work. Because it's your coursework perhaps you shouldn't just use whole code but write own one, but I would like to show you and general idea,
Add variable number of occurrences of "string" to struct:
I'm implementing a libfuse filesystem. When a file is opened, I read the file attributes and store them in a hash table keyed with the file handle I generate. This serves two purposes: to maintain a collection of open file handles and to cache the information I retrieve during opening.
Of course, nothing is stopping user code from trying to pass an invalid file handle, i.e. read from a file that's not open.
There are a number of error codes that I can return from the
read function, but it's not clear to me which is the one that is expected in such situation.
ANSWERAnswered 2020-Jan-02 at 06:11
As you can see in the POSIX standard, the correct value to return would be
[EBADF] The fildes argument is not a valid file descriptor open for reading.
That said, if user code passes an invalid file handle, the Linux kernel will return
EBADF to the user before you, or fuse, get any say on the matter.
