patricia is a Go library typically used in Networking, TCP applications. patricia has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

A Go implemenation of a [patricia tree] (radix tree with radix=2), specifically for tagging IPv4 and IPv6 addresses with CIDR bits, with a focus on producing as little garbage for the garbage collector to manage as possible. This allows you to tag millions of IP addresses without incurring a penalty during GC scanning. This library requires Go >= 1.9.

Most efficient way to loop through a file's values and check a dictionary for any/all corresponding instances

I have a file with user's names, one per line, and I need to compare each name in the file to all values in a csv file and make note each time the user name appears in the csv file. I need to make the search as efficient as possible as the csv file is 40K lines long

I think @Tomalak's solution with SQLite is very useful, but if you want to keep it closer to your original code, see the version below.

Effectively, it reduces the amount of file opening/closing/reading that is going on, and hopefully will speed things up.

Since your sample is very small, I could not do any real measurements.

Going forward, you can consider using pandas for these kind of tasks - it can be very convenient working with CSVs and more optimized than the csv module.

How to create a parent-child dataframe from an existing pandas dataframe of hierarchical structure and arbitrary shape?

Asked 2022-Mar-23 at 23:12

How do you convert a given dataframe with a hierarchical structure and arbitrary shape (say, similar to the one below) into a new dataframe with a parent and child column?

Edit: Note that a constraint is that a child cannot be its own parent.

ANSWER

Answered 2022-Mar-17 at 17:41

If I understand your description correctly, for each row we want to evaluate the following conditions to decide whether include? = 1:

The row's group size for organisation_id-patient_id-date-consultation_mode is 1
The row's group size for organisation_id-patient_id-date-consultation_mode is greater than 1 AND the row corresponds to a:
1. Doctor AND is the first among doctors with the same id/name
2. Nurse AND is the first among nurses with the same id/name
3. Support AND is the first among support AND is part of a organisation_id-patient_id-date-consultation_mode group that has no doctor or nurse

This logic will create the "intermediate" table. To create the "final" table, we go through each category of consultation_mode and professional_role and set Nr_consultations_per_Pt_day = 1 if there's a corresponding entry with include? = 1.

Based on the above expectation, here's how I'd do it:

How to remove or mimic the negative lookbehind?

Asked 2022-Mar-04 at 08:01

I have already gone through Negative lookbehind equivalent in JavaScript, javascript regex - look behind alternative? but I am unable to get the correct regex. I have really tried myself, but not successful. I have did multiple trials to get the answer. As was unsuccessful hence posted this question.

I have a regular expression. It is working perfectly fine in the Chrome browser, but I face an issue in Safari and IOS. The issue is the negative lookbehind. Is there a way to either remove or mimic the negative lookbehind, so that the same expressions can work in all 3 environments?

How can I get the font family name from a .ttf file in golang?

Asked 2022-Jan-29 at 09:54

As we know, a .ttf(or otf) font file's file name is not always the same with the font family name, for example, if I rename Arial.ttf to abcd.ttf, it's font family name is still Arial, so is there a package or library in golang to parse .ttf and get that name?

I've tried freetype, but it seems no method can get it

...

ANSWER

Answered 2022-Jan-28 at 14:55

It is possible to read the data of a ttf file with this go library freetype, you just need to provide the font data and it will parse all the data. There is also an article about reading ttf files content manually with javascipt here.

Edit: If you are using freetype to get the family name or other information, you can use the Name reciever function of the struct, it accepts a NameId which is an alias for uint16. (You can find the complete table of the valid value here in the name id codes section)

for example, you can get the font family name by using the following code:

QUESTION

Make for loop change after 4 iterations--ie run for loop in sets of four, with separate function in between

Asked 2022-Jan-13 at 15:05

I dont know the proper way of describing this so please bear with me. Basically, I have a function in R that reads through a data frame and pastes the contents in a specific order--its used to write a tex file for LaTeX so I can make hundreds of labels very quickly.

Ive attached a simplified version with just the for loop. What I am hoping to do is have the code loop through four rows of the data, do something different for the fifth, then return to the next four rows of data. In the example below, it would be pasting one phrase for most of the rows and on the fifth it would paste something else--each based on the data frame.

For my actual code I want to flip the label horizontally to use up the most amount of paper possible. See attached photo., But in reality it all comes down to the for loop I think.

A small and simple fix would be to filter the data with [[ instead of [. The higher level difference between the two is explained in this post The difference between bracket [ ] and double bracket [[ ]] for accessing the elements of a list or dataframe .

Here, [[ always returns a vector whereas [ returns a dataframe which works for most of the cases as you expect but fails when there is no selection made for var2 yet meaning when var2 is empty.
