kandi X-RAY | momo Summary
This is a proc_macro crate to help keeping the code footprint of generic methods in check. Often, generics are used in libraries to improve ergonomics. However, this has a cost in compile time and binary size. Optimally, one creates a small shell function that does the generic conversions and then calls an inner function, but that makes the code less readable. Add a #[momo] annotation from this crate to split your function into an outer conversion and a private inner function. In return, you get some compile time for a tiny bit of runtime (if at all) – without impairing readability. Conversions currently supported are Into (.into()), AsRef (.as_ref()), and AsMut (.as_mut()). See enum Conversions in code.

QUESTION
I am writing a program that should memorize all the words that begin with 'm' in a linked list. The problem I am having is that when I am trying to read the file line by line, divide the line by words using a token pointer and strtok. Then I insert the token into a linked list but when the text is spread to multiple lines.
ANSWER
Answered 2022-Jan-26 at 22:53strtok returns pointers into the input string.
If you store these pointers in your list and then read a new line into the same buffer, the data at the saved addresses may get overwritten with the text from the next line. As noted by Barmar in a comment, if getline calls realloc, the memory may even become invalid.
At the end of the processing, the buffer will contain text from the last line and possibly parts from longer lines and all saved pointers will either point into the same memory range or maybe to invalid memory which results in undefined behavior when you try to use the pointers as strings.
You have to create copies of the strings when/before storing them in the list, e.g. by using strdup (or malloc and strcpy).
QUESTION
I have a dataframe that contains stock data and is grouped by stocks (see attached image for example), the index is each minute of data for each stock and the second column is the stock symbol.
I am trying to apply 'Pandas TA' indicators to the dataframe by using groupby so that each stock's data is treated separately and also uses Pandas TA's built-in multiprocessing. I have a main backtesting file that calls this function to add indicators to the raw data (raw data is Open, High, Low, Close, Volume), but this code only returns a blank dataframe.
...ANSWER
Answered 2021-Dec-23 at 23:52Two options 1) using apply(), 2) iterating over groups. For my dataframe with just three symbols and shape df.shape (12096, 7), both methods took the same time using %%timeit - 3.4 seconds. You can do some testing on larger dataframes to see if one method is faster than other.

I am not finding a way to organize the following dataframe in Pandas to show all information I need. I have the following dataframe:
...ANSWER
Answered 2021-Jul-15 at 22:57Looks like you want the minimum ID for each date, and I think you would then want to use that minimum ID for every instance of that date. If so, do a separate groupby to get just that data, then merge on date. See this toy example:
QUESTION
I am trying to use autocomplete property
showPanel: boolean Whether the autocomplete panel should be visible, depending on option length.
From documentation I understand, autocomplete panel will extend its width depending on mat options length. Please correct me If I am wrong. Link to offcial documentation offcial documentation
I have one mat option which is very long in length and even after applying showPanel; matpanel has not expanded. I am not sure whether I am using the property correctly. Here is what I have tried
template.html
...ANSWER
Answered 2021-Jul-14 at 14:09You got it wrong, sadly. This is NOT an input so it can't be set - it's just a property that informs whether the dropdown will be visible. It's based on the length of the options, i.e. if there are 0 options (e.g. user types something that is not part of any provided options) this will return false. You can find the source code for this property here, and it's value is set here - so updating it manually will make no difference.
You can set the width of the dropdown panel by setting the panelWidth property (docs here) on your autocomplete. The reasoning for this being a static value is that otherwise the dropdown would change width based on the currently rendered options, which would be terrible UI (as the width could change after every typed character).
Other than that, you can either change the override the styling of the panel and items, but personally I would advise against that.
