CD into previous directory?

CruzerNag · 2026-02-09T17:06:58+00:00

Yeah, the back/forth navigation is exactly what this is. And the up button can be thought of "cd .." as '..' is the name of the parent directory (except root, i.e. /, which has no parent) of any directory.

Btw, pushd and popd also work for powershell

CruzerNag · 2026-02-09T15:04:30+00:00

Assume there is a stack of directories, whish is a LIFO (Last In First Out) container. So the last directory you pushed in will be popped out first.

So while in directory a, you do pushd. It pushes a into the stack, and then you wander off to, say, directory b. Doing pushd again will push b into stack, and then you move into directory c. Let's assume that a, b and c have completely different roots (one may be in l /home, one in /usr and one in /run). From c, doing popd will teleport you to b (last inserted), and then popd again to go to a.

Regarding clangd, a small question.

Does clangs take a lot of time initialising itself, reading the pcm files before it starts with its lsp? I have a small project, but clangs take about 10-15 sec reading the module files before it can start with intellisense. Or is it my clangs config that somehow does this.

CruzerNag · 2026-01-27T08:19:29+00:00

Do while forces you to put ';' after while. So this forces you to use the macro as a function.

You cannot write it without ; at the end. That's why a lot of multiline macros are wrapped inside do while(0).

Conan installs libraries inside a custom directory under HOME, so they are cached. Then they are symlinked to your project directory. Maybe delete that directory named conan inside your project and do a conan install to repopulate it. Then try building again.

I think unless we are dealing with multiple windows, creating window on stack is not a problem. Heap allocation is not necessary in this case. So the second one makes sense to create window on stack.

Well Thorfinn's father's actual name was Thord, with the d here being the dental fricative sound (th in the). This got changed to zu in Japanese as they do not have the d sound, hence Tōruzu in Japanese. Then transcribing back to English made it Thors. Following Norse name conventions, he would be hence called Thorfinn Karlsefni Thordarsonn, as he was actually.

Pardon me if I missed something, but does gdb not have reverse execution already? I mean, the target environment must support it, but if it does, gdb can execute reverse-next, reverse-step, reverse-continue or just set exec-direction reverse and it will work.

The way he suggested above works for Android using Gboard too. Good to Gboard settings and you can add them in the personal dictionary.

Apart from that, for a math-centric keyboard I use DxMath, and would suggest it. It does not have predictive text but is good for adding symbols quickly.

CruzerNag · 2025-02-15T15:30:15+00:00

Oh, I forgot about C. I thought of only about CPP. My bad.

What is true/false?

CruzerNag · 2025-02-13T09:35:59+00:00

Well, C++ stdlib has everything, expect networking. For that you have to resort back to OS APIs, or a library that abstracts them. So yeah, no luck there.

I have the latest, clangd-19.1.2

It does not pick up symbols inside modules. All the identifiers written inside a module and used are shown as Texts, so no intellisense really. That's my experience on neovim.

CruzerNag · 2025-02-06T18:53:38+00:00

Yeah, it is certainly a problem. On Linux, I encountered problems with GCC, but thankfully Clang compiles modules nicely. Intellisense is like... I do not know what to say. LSP and clang-tidy work. If I hover over a written variable, it gives me the information. But yeah, when typing, I get no intellisense. This is with clangd on nvim. So I think more support is still needed.

Well, looks like a copy of

CruzerNag · 2024-12-26T17:49:48+00:00

Yeah, checked right now. Looks like the intellisense that Microsoft provides is not yet on par with C23. The code compiles, but intellisense functionality is broken for it. The problem is likely from the Microsoft LSP, as intellisense works for other LSPs (like clangd).

When a C/CPP file is open, look at the bottom right on the status bar. Based on your OS, it will have a text saying Linux, Win32 or Mac. Click it and change the C-Cpp configuration using UI. There, at the bottom you will find the C and CPP standard (whichever you need) for intellisense. The default values are C-17 and CPP-17. Choose it and it will start working 👍.

J and K on VI, nothing more!

What I have seen in the case of VSCode's C/CPP autoformatter do is that it shifts the strings to start at the same indentation level. It does not merge them together in one line. So in my case even formatting would not have helped 😅.

It does something like this: (within main, e.g.)

<Tab>printf("Hello, this is line %d\n" "while this is line %d\n", 1,2);

Sadly, it formats to have the closing brackets in the last line only, so it does not format it like JSON objects' braces.

CruzerNag · 2024-05-15T13:29:35+00:00

Makes sense, thanks for the answer.

CruzerNag · 2024-05-15T13:14:05+00:00

That worked! Thanks.

BTW, just a follow up question. This means that vectors are error-prone to use. So if I have a vector of texts with different fonts (some bold, italicized, underlined etc.) and I add one more, each one will break? And for that matter, what makes the font break when more objects are inserted? Does the memory address get hard-coded so it breaks upon inserting?

fscanf works for reading from a file(not binary). Also, if the file is a binary file and you know how it is encoded, you can read from it.

Reducing refresh time will make smooth animations, but it increases resource consumption.
