kandi X-RAY | rgo Summary
rgo was a work-in-progress Go compiler, written in Rust. This was primarily a fun learning project. I chose Go as the source language because C compilers have been written over and over, and I wanted to do something new. Go's spec is pretty simple, so it seemed like a good choice. The fact that is has a GC also made implementing a compiler for it more challenging and, therefore, more interesting. Additionally, Go's reference implementation uses a custom backend for optimization and codegen, while rgo was to use LLVM for optimization and machine code generation.

QUESTION
I am just getting started with Multiprocessing & Python, and I am needing some help catching Control-C in my program. The script that I am making is going to read in a file, and then perform some tasks on each line. Before anyone comments on I/O and the advantages/disadvantages of multiprocessing, I am aware :) these tasks lend themselves to be very multi-threaded friendly.
I have the following code, and from the documentation, I would expect it to work, however it is not catching my keyboard exception! ARRGH... Please help
Running on Win10 if that makes any difference:
...ANSWER
Answered 2020-May-23 at 17:48At the time when you use Control-C the program probably is at pool.join() waiting for all threads to be finished. The pool.map function just starts all the processes but does not block. This means that at the time the KeyboardInterrupt occurs it is not catched because the program is not inside the try-block.
I am not too sure about the best practices here but I would try:
QUESTION
TLDR; Is there a way (using a type map or some other solution) to give dynamic result sets a default name, such as "(No Column Name)" in Dapper when no column name is supplied?
I am writing a query editor that allows users to write and run user-supplied queries against MS SQL Server databases. I've been using Dapper for all our querying and it has been working beautifully for 99% of what we need. I've hit a snag though and I'm hoping someone has a solution.
The query editor is similar to SSMS. I don't know ahead of time what the script will look like, what the shape or type the result set(s) will be, or even how many result sets will be returned. For this reason, I've been batching the scripts and using Dapper's QueryMultiple to read dynamic results from the GridReader. The results are then sent to a third party UI data grid (WPF). The data grid knows how to consume dynamic data and the only thing it requires to display a given row is at least one key value pair with a non-null, but not necessarily unique key and a nullable value. So far, so good.
The simplified version of the Dapper call looks something like this:
...ANSWER
Answered 2020-Feb-20 at 09:13I suspect this is because the dynamic DapperRow object is actually not a 'normal' dictionary. It can have several entries with the same key. You can see this if you inspect the object in the debugger.
When you reference rowDictionary[x.Key], I suspect you will always get the first unnamed column.
If you call rowDictionary.Remove(""); rowDictionary.Remove("");, you actually only remove the first entry - the second is still present, even though rowDictionary.ContainsKey("") returns false.
You can Clear() and rebuild the entire dictionary.
At that point, you're really not gaining much by using a dynamic object.
QUESTION
This time the bug i'm facing is not code related but design related. In the login page I have;
text view just saying Log In, then I have two input fields for email and password, the third widget is where the bug is. It is Forgot Password and it is constrained to the right side of the phone screen.
Now on my device, it is like "Forgot Password". But when I installed the application on another device, it went like "Fo rgo t Pa ss wor d?"
Words scattered vertically.
Here are the code screenshots,
The forgot password widget, I mentioned. then finally the button login.
I dont know whats up? Any suggestion guys?

I'm an amateur at writing scripts, working to update one I was using in 2012 that would navigate to one of several pages in a list and pull table data. I noticed today I was not pulling any data and when looking in the page source there is a second HTML doc.
...ANSWER
Answered 2018-Oct-19 at 05:16I don't know if page interacts differently from reading in from file. If I read your HTML in from a file I can get 927 td elements with the following code. It you try transferring the HTML from the page into an HTML document it should all end up in the same DOM tree.
I am wary of positional matching given how ugly the HTML and the fact pages can change but I can retrieve the tender # with

I am trying to understand carriage return(\r). So I have written the code below. If i run the below code, I am getting the output is "go".
Method1:
...ANSWER
Answered 2018-Sep-03 at 10:52You should get "goi" in both cases. You can test it here.
Carriage return is literally just that - it returns the carriage, i.e. it goes back to the beginning of the line.
So when you print "chi\rca\rgo", this will happen to the output:
QUESTION
I'm still new to programming and brand new erlang (2 week newbie!). I edited slightly so atleast it'll compile and run. But I still can't figure out the concept of sending the results to a "joiner process" to join all the seperate results.
It does split and send the "chunks" an received to count the chunks. Just don't know how to get all those processes to join their individual results. I sort of understand the concept below, but have no idea how that's implimented. I've been trying for many days and hours to get it to this point, but can't get it to do anything without getting errors or unbound variables, etc.
...ANSWER
Answered 2017-Apr-02 at 14:30You need to synchronize the output of go function. Don't spawn function inside go because i am seeing that all results are going to different process(receive_results).
Best solutions is spawn one process for joining result inside load function only(this process takes self() as Input so that it can send final result back to load function).Then pass that join process reference(J_PID) to all worker processes which will send back result to join process.Join process is loop of kind of receive_results.Loop terminates when all chunks are processed.Add a clause to terminate join process.While terminating, join process will send back result to load function.
Sudo code:
J_PID = spawn join(self())
spilt(J_PID,....)
wait_for_result(receive Result -> R)
