QUESTION
Every time somebody asks a question about delete[] on here, there is always a pretty general "that's how C++ does it, use delete[]" kind of response. Coming from a vanilla C background what I don't understand is why there needs to be a different invocation at all.
With malloc()/free() your options are to get a pointer to a contiguous block of memory and to free a block of contiguous memory. Something in implementation land comes along and knows what size the block you allocated was based on the base address, for when you have to free it.
There is no function free_array(). I've seen some crazy theories on other questions tangentially related to this, such as calling delete ptr will only free the top of the array, not the whole array. Or the more correct, it is not defined by the implementation. And sure... if this was the first version of C++ and you made a weird design choice that makes sense. But why with $PRESENT_YEAR's standard of C++ has it not been overloaded???
It seems to be the only extra bit that C++ adds is going through the array and calling destructors, and I think maybe this is the crux of it, and it literally is using a separate function to save us a single runtime length lookup, or nullptr at end of the list in exchange for torturing every new C++ programmer or programmer who had a fuzzy day and forgot that there is a different reserve word.
Can someone please clarify once and for all if there is a reason besides "that's what the standard says and nobody questions it"?
...ANSWER
Answered 2021-May-19 at 19:55Objects in C++ often have destructors that need to run at the end of their lifetime. delete[] makes sure the destructors of each element of the array are called. But doing this has unspecified overhead, while delete does not. One for arrays, which pays the overhead and one for single objects which does not.
In order to only have one version, an implementation would need a mechanism for tracking extra information about every pointer. But one of the founding principles of C++ is that the user shouldn't be forced to pay a cost that they don't absolutely have to.
Always delete what you new and always delete[] what you new[]. But in modern C++, new and new[] are generally not used anymore. Use std::make_unique, std::make_shared, std::vector or other more expressive and safer alternatives.

i use parrot security as my daily distro. its mate terminal is transparent so is vim .but i wanted to get auto complete and used some plugins.auto complete window appears to be in pink which looks really ugly in semi transparent black background.i changed the theme and it was fixed but so was gone vim transparency .
in short word (1)i have to keep the default (2)i have to keep transparent vim (3)i have to change the auto complete window from pink to semi transparent black
here is my init.vimrc
...ANSWER
Answered 2021-Jun-09 at 19:27If you are using neovim there is an option called :h pumblend which can be used to change the transparency of the popup menu.
Are you sure gruvbox caused your vim to lose transparency? I am not sure if vim is able to change a terminal emulator's transparency. I or someone else might be able to advise you better if you post pictures of what has changed.
QUESTION
I'm trying to use fuzzy string matching to convert strings to specific ids and perform grouped summarization using dplyr. The basic idea is combining imperfect gene sequences into a single gene name via a dictionary lookup approach and counting how many times the gene is detected. This way, counts for sequences aaaaaa and aaaxaa match to gene1 and get added together.
I can do what I want using for and if statements via a row-by-row comparison of the raw data against the dictionary but I find this will be inefficient when I scale up (raw data files have 15k rows on average, the dictionary has 200 rows). Please see my solution below I'm trying to improve and let me know if you can think of a more efficient and elegant way of doing this.

QUESTION
i have a dataframe with many col names having _paid as part of the name (eg. A_paid, B_paid. etc). I need to fill miss values in any col that has _paid as part of the name. (note: i am not allowed to replace missing value in other cols with no _paid as part of the name). I tried to use .fillna(), but not sure how to make it do fuzzy search on col names.

QUESTION
There's tons of info about Unicode codeunits, codepoints, etc, but I'm still a bit fuzzy about converting combined characters, graphemes, etc using byte-streams (required by libiconv).
Currently I'm only interested in converting between UTF-8/UTF-16/UTF-32 using libconv's iconv(), which expects the byte-lengths of both source and destination buffers as arguments.
Question: Is there a safe way to calculate fast the maximum possible bytes-length of the target buffer, based on the already known bytes-length of the source buffer?
Let's say for example, converting from u16buf to u8buf with a known u16byteslen (excluding 0x0000-termination if any). In the worst-case scenario, there will be 1 two-byte unit per codepoint in the UTF-16 source buffer, corresponding to a 4 single-byte units per codepoint in the UTF-8 target buffer. Is that enough to safely assume that the UTF-8 target buffer can never be longer than 2 * u16lenbytes?
I've actually experimented with that and seems to work, but I'm not sure if I'm missing corner cases involving combined characters and grapheme clusters. My doubts come from my ignorance regarding how those things are converted across these 3 different encodings. I mean, is it possible for a grapheme to need say 3 UTF-16 codepoints but like 10 UTF-8 codepoints when converted?
In that case, doubling u16lenbytes wouldn't suffice, right? And if so, is there any other straight forward way to pre-calc the maximum length of the target buffer?

Yes.
to UTF-8 to UTF-16 to UTF-32 from UTF-8 ×2 ×4 from UTF-16 ×1 ½ ×1 from UTF-32 ×1 ×1You can calculate this yourself by breaking it down by code-point ranges. Pick a source and destination column, and find the largest ratio.
Code Point UTF-8 length UTF-16 length UTF-32 length 0000…007F 1 2 4 0080…07FF 2 2 4 0800…FFFF 3 2 4 10000…10FFFF 4 4 4Combining characters and grapheme clusters do not affect anything. Encodings simply convert a sequence of Unicode scalar values to bytes, and they are very straightforward.
Note that you will need to add two extra bytes when converting to UTF-16, and four extra bytes when converting to UTF-32, since these encodings will add a BOM U+FEFF to the beginning of the text. (If you don’t want that, use one of the BOM-less encodings, like UTF-16BE or UTF-16LE.)
I mean, is it possible for a grapheme to need say 3 UTF-16 codepoints but like 10 UTF-8 codepoints when converted?
No. That would imply some other kind of conversion, like a decomposition. The number of scalar values input is equal to the number of scalar values output, with the possible addition of U+FEFF byte order mark at the beginning. (I say "scalar value" instead of "code point", because "scalar value" excludes surrogates. If you are transcoding text which might have errors or might be garbage data, it doesn’t change the size of the result.)

This seems really simple but for some reason, I don't understand the behavior of agrep fuzzy matching involving substitutions. Two substitutions produce a match as expected when all=2 is specified, but not when substitutions=2. Why is this?

I am trying to perform entity matching for the first time and want to "get rid" of the obvious matches first, so I can focus working with the fuzzy cases. I have a dataset of almost 600.000 entries containing information about clothes.
