I always put redundant parentheses in formula like ((b - a) / 2) + a because I just don't trust the compiler.20

Sometime I’m developing in Rust and I do something wrong.

Never look at your computer when it's compiling, it can sense you and it becomes more prone to errors.

Ok. Yesterday I finished building my compiler I have to say: it was a pretty darn big thing with 7000 Lines of code.
I did it alone and with almost no help.
I wanted to give some advice in case someone wants to program a compiler. I knaw its useless in times of lex and yacc, but anyway.
-have a good idea for the language
-learn about parser/lexer
-learn assembler
-do it like me: output the assembler to a file and let it assemble/link by the linux standart-tools (call the commands)
-Have fun. Fun is essential in coding
I hope I was able to help people who want to build a compiler alone... Yau can always ask questions ;~)

[long]
When searching for internship via school I found this small startup with this cute project of building a teaching tool for programming. There were back then 2 programmers: the founder and the co-founder.
Then like 1 week before the internship started, the co-founder had a burnout and had to get off the project, while the company was so low on budget the founder, aka my new b0ss, had to work separate jobs to keep the company alive. (quite metal tbh)
It's funny because I'm a junior developer, 100%. I've been coding as a hobby for around 8 years now but I've never worked in a big company before. (No exception to this workplace either)
First project I get: rewrite the compiler. The Python compiler.
"But wait, why not just embed a real compiler from the first case?"
-nanananana it's never simple, as you probably know from your own projects.
The new compiler, as compared to existing embedded compiler solutions out there, needed these prime features:
- Walk through the code (debugger style), but programmatically.
- Show custom exceptions (ex: "A colon is needed at the end of an if-statement" instead of "Syntax error line 3")
- Have a "Did-you-mean this variable?" error for usage of unassigned variables.
- Be able to be embedded in Unity's WebGL build target
All for the use case of being a friendly compiler.
The last dash in the list is actually the biggest bottleneck which excluded all existing open-source projects (i could find). Compliant with WebAssembly I can't use threads among other things, IL2CPP has lots of restrictions, Unity has some as well...
Oh and it should of course be built using test-driven development.
"Good luck!" - said the founder, first day of work as she then traveled to USA for **3 weeks**, leaving me solo with the to-be-made codebase and humongous list of requirements.
---
I just finished the 6th week of internship, boss has been at "HQ" for 3 weeks now, and I just hit the biggest milestone yet for this project.
Yes I've been succeeding! This project has gone so well, and I'm surprising myself how much code I've been pumping out during these weeks.
I'm up now at almost 40'000 lines of source and 30'000 lines of code. ‼
( Biggest project I've ever worked on previously was at 8'000 lines of code )
The milestone (that I finished today) was for loops! As been trying to showcase in the GIF.
---
It's such a giant project and I can honestly say I've done some good work here. Self-five. Over-performing is a thing.
The things that makes me shiver though is that most that use this application will never know the intricates of it's insides, and the brain work put into it.
The project is probably over-engineered. A lot. Having a home-made compiler gives us a lot of flexibility for our product as we're trying to make more of a "pedagogic IDE". But no matter that I reinvented the wheel for the 105Gth time, it's still the most fun I've had with a project to date.
---
Also btw if anyone wants to see source code, please give me good reasons as I'm actively trying to convince my boss to make the compiler open-source.
Cheers!

The myth about the missing semicolon. I don't get it, if your editor doesn't pick it up, the compiler og interpreter will. How is this a common problem?4
-
Dear Santa, please bring me a compiler that generates compile errors instead of runtime bugs. Thanks.10
-
Please actually pay attention to compiler warnings. They exist for a reason beyond just being a nuisance. If you're willingly ignoring warnings then you're accepting unnecessary risk into your project.4
-
I've just managed to add the ability to call functions to my compiler. Currently, the capabilities are rather limited but I am pleased with it.
It keeps the schematics of the source code well enough that it can handle
recursive calls.
:D
On the Image, you can see the program's output (left), the generated x86_64 assembly, and the source code of the compiled program (bottom).

991 little BUGS IN THE CODE1 -
Me after a long coding session with a well prepared working flow: I am such a great computer scientist, I can conquer the world.
Right after that I found a repository for computer science papers and got immidiately hooked. Well, the level of knowledge and theory is so immense that it brought me back to ground of reality again: I know so little that it is almost ridiculous, even if I read and code 16 hours a day I may never understand computer science as a whole.
Le me sad.11 -
I fucking nailed my c exam.
Had to write C on paper today. Fuck my uni for that. But I think I aced it. I coded C for weeks and hopefully finally payed off.
Fuck coding on paper though. They are just too lazy to make something digital. But man at least let me get some compiler messages. It's not like anyone codes without compiler messages anymore. -

Day 2 in ComSci class (following my last rant)
"Okay, so! All of the schoolwork and homework will be done on paper and pen, submit and I will grade it. Only once, no second chance"
Okay. Okay. This went over my head. What are you gonna do? OCR the code into the compiler, compile it and run to see if we fucked up to give us an F? What are you, god? Here's a brilliant idea, teach them Assembly! Guaranteed error to give us Fs! FUCK YOU3 -

Not quite a interview question, but in a competition (I had build a compiler) the jury (they all told me they had all studied informatics) asked me what a compiler is... Not in a "lets try to catch him off manner" but rather in a "i am too stupid for this world manner" he asked me what a compiler was... And it got even worse: my compiler is based on linuxes utils (nasm+ld) the guy didnt know about linux. Assembler was much too much for him and when my compiler threw an error (I wanted to show them the error system) he told me I shouldnt present unfinished projects... Atleastthe other two were really nice and i still got 2nd place (behind a person who prorammed an Nxt thingy)7

Making my own game console.
I work with FPGAs and have access to a bunch of pretty nice dev boards, so building a workable CPU and GPU is definitely possible. I even have architectures for both in mind, and have planned ways to get compiler support (i.e. just use RISC-V as the ISA as much as possible so that I can reuse an existing RISC-V compiler with minimal changes) so that I don't need to write assembly.
But, lack of time. Sigh.4 -

Lets learn bubble sort!
Type the following code to Visual C++ 1998 and compile it. Then run it. Write the output to the paper i just gave it to you.
Reality:
• Takes 5 mins to compile and run
• Too many errors in the given code so obscure output
• Teacher thinks we are so smart that we can understand c by typing and looking at the output.
The worst part:
• Different output per compiler
- Correctly compiles in the compiler in VC++ 98.
- Differs in GNU GCC, compiles wrong
- sends out obscure dummy output in VS2015~2017
- Works well in tutorialspoint.com compiler
WTF is this, guys?
@@@@@@@@@@@@@
Oh, and i have gone off topic...
Why does he think we are smart that we can understand bubble sort, and 4 more by only typing the code and looking at the output without knowing how does this algo work?

How on earth are there people in their second year of a computer science course who are unable to understand how to read build errors. It's honestly not that hard, just look at the fucking build log and see where the error is and what type of error it is, but yet they don't bother reading the log and say that their "compiler is broken" when their 5 line code won't work.
If this was still first year I'd understand since many of the class didn't have much programming knowledge, but if you're in your second year and you struggle with this (that too for a Hello World script) it looks like you aren't even bothered and just expect the computer to magically understand what you mean.3 -

Someone around here once said that they believe that Rust compiler errors are generated by first sending the compiler noise to some dude in India and then they parse the errors and send them back to the compiler.
This was not a nod against our friends from the land of India, but instead, I think, a praise.
Thus I would like to add a request to the rust devs to see if they could include more "trademark Indian" sassy remarks in the messages that the compiler generates. But I am afraid that they think I am being racist or something.
For reference: My Indian friends are all beyond sassy in the way they clap back at mfkers when having friendly arguments, I have been left with a "well, damn" in multiple occasions because I am incapable of reaching that level of sass myself.9 -
Once again, we delivered our semester project and this time, we added working concurrency to an existing functional language compiler, which is pretty cool.

Can we please stop making everything in javascript? Pretty please?
Like, I get it, js makes it easier to find developers and speeds up development, but writing a compiler to run on node? That doesn't make any sense to me. Typescript is taking ~11s to compile a medium-sized project, out of which ~9s are just type-checking (if I disable type-checking it takes ~2s to compile). Even Rust, which is considered to have a slow compiler (because of the borrow checker I assume) takes less time to compile a project of roughly the same size.
This is getting very irritating. If I want to keep type-checking, every single time I make a change on a single file I have to wait 11s before any tests start running. This was heavily affecting my productivity (and sanity), so I decided to disable type-checking and threw out the window 90% of Typescript's advantages.

I am a single-pass compiler.
Why?
Well, when I have to do the food shopping for the week, I have a look at the buying list, keep the things in mind, go through the shop exactly once and everytime I see a match with the list, I put it into the shopping trolley.
Efficient and quick.
Soo, on the other hand, my girlfriend is a multi-pass compiler.
What that mean, you ask?
Well, she doesn't have any look at the buying list until she is in the shop. Then, she runs through the whole building until she finally finds the first thing on the list... and repeats with the next one until there's no entry left.
She needs three times longer than me for this, is totally exhausted after it, and, not forgetting, then SHE is angry about ME, because I wanted to have these "special" sweets she had too run through the shop twice for because she couldn't find it at first try.1 -

My weirdest dream about programming?
I was sitting with my buddy and we were programming, and literally, verbally arguing with compiler that he should compile, and he was spewing out different errors each time we compiled, and it somehow matched our arguments, so it literally was "replying" with different kind of errors ;-;
I mean, we didnt change code, but tell to compiler "no, no, no, you dont understand. This error is wrong, becouse here and there is this and that and it just should work" **pressed compile again and gets different errror**
Yes, that was after few nights of c++.
Edit:
yes, in that dream compiler was spewing out bullshit errors that didnt made sense.2 -
My idiotic teacher doesn't know the difference between Java and JavaScript , asked us to use a old version of Code::Blocks(some c/c++ IDE) just because she thinks that a update would modify compiler in such a way that basic code would never give the same output , she blames the compiler just because she isn't capable to see her mistakes and gives me bad grades just because she walked through college and I didn't.2

Compilers should just work for raw C with only static memory allocation. This isn't the bad old days where a couple of dudes wrote a short book explaining how C might probably should possibly work. I hear supposedly we have standards now.
Well, last week I lost 2 days to our compiler randomly forgetting that it wasn't okay to put a globally allocated uint32 at an address ending in 9. What? It had been handling this case without issue for more a year, but now after changing completely unrelated code we have this problem.
I'm not sure how to even deal with this idiocy so no doubt I'll continue working on it this week, too.
Thanks a lot, GCC.1 -

It's about the The Ken Thompson Hack:
"Ken describes how he injected a virus into a compiler. Not only did his compiler know it was compiling the login function and inject a backdoor, but it also knew when it was compiling itself and injected the backdoor generator into the compiler it was creating. The source code for the compiler thereafter contains no evidence of either virus."

Well. I have to go on a competiton about informatics in two weeks.
This is my programm: https://github.com/MaximilianJugend...
As its a competiton for kids, I dont expect anybody to match a compiler (not trying to be rude. The competitors try to compete with nxt programs.), but it wouldnt look nice, if there were Bugs. So shoutout to german people who are bored to death: could you please test my program and open as many issues as possible? ;) thanks in advance5 -
That Feeling when Eclipse removes Maven dependencies, put his compiler and Build Path to Java 5 when you're with Java 8, and cookies aren't good since it's not yours.
Yay for git -
Me during HR interview.
Q) What makes you Happy?
Ans: when my code compiles successfully in the first attempt.1 -
I have an assignment where I have to make a language that has a purpose, for example: make sql easier to understand or in my native language.
Do you guys have any ideas?10 -
Use Rust they said. It will be much less hassle they said.
And now rustc just stops working in the middle of compiling. No error or anything it just doesn't want to continue compiling so I'm stuck forever on "Building ...". I thought I would never have to experience this again after deciding to pretend C++ doesn't exist but alas systems programming appears to forever be a right pain in the ass6 -
I've been watching hours of Rust programming streams. Looks like no one knows what they're doing. People depend on the compiler to fix their errors but can't write one line without getting an error.7

(heading)How a programming language is created? Because I want to make my own.(heading)
I am learning C and next I will learn C++, SQL,DS&A, Assembley, Lex&Yacc,Operating Systems, Computer Arcticture, Computer Networks because I think it's enough for my goal. The only reason I am learning this, to make my own C++ clone with my own knowledge. But I really don't know how can I create my own programming language like C++ from scratch. Like what are the first steps to began with. As I know that C, first step is Preprocessor then Compiler then Assembler then (Loader/Linker).
Anyone please give me a step by step guide like learn this language first then this then this. So I can finally reach that amount of knowledge which I can implement to create my own programming language like C++.6 -
Whether I care to admit it or not....
My most prolific teacher has been compiler error messages (oh, and intellisense). -
Is there a programming language or library that lets you customize the shit out of it? Something like C++ templates but with special symbols as custom operators?7
-
shower thought : if i made a compiler for my own programming language and it compiles to python. would it be a python dialect or a new programming language?5
-
Python's ast package is the coolest thing I've recently came across. If you're a compiler writer, you can translate your language's source code into python's ast. And your language has instant access to all of the python's libraries.
-
I still wonder why there's this "a man writes more optimised code than compiler" stuff. Why?
Compiler is automated work, in the worst case it should be able to create multiple e.g. asms and compare the time, right? You can dump all instructions into compiler, it should be able to choose the right one even if it would compile whole days, right? You can't be possibly serious with such a statement.
No "time" arguments, please.2 -
I was in my IDE writing up a new program, but my compiler didn't accept the encoding format of the files. Because I used special characters, it flipped a lot of encodings around. Then I changed my projects master encoding, then all of the source files they all messed up. The all the files were composed of "????????" I went to a backup and they were messed up too. I exploded... Control Z couldn't even be my hero this time.3

I just started learning Norwegian. Does anyone know how I can enable branch prediction in the compiler?1

Compiler Question
Things you hate/don't like about JS/Javascript/ECMAscript/ES. Or what do you think are the issues4 -
Just coded a simple SDL program after a two weeks break without a compiler error(more than 100 lines) from memory . Something must be missing . I don't trust this program 🤔1
-
Hate when I forget I rename x variable to y just for the compiler to fuck me in the ass by telling me x variable doesn't exist. FFS!!!1

Compiling a project (Not BIG but still pretty big)
C# compiler : YOLO, you have 12 Cores ? I'll use 12 cores. BAM : 3 seconds, compiled !
SASS compiler :
Rolf, I'm gonna take file by file, recompile all dependant files to produce a single file. 2 Seconds per file. X 150 files.... 6 Minutes SASS is still running....2 -
"Unexpectedly found nil while unwrapping an Optional value"
What dev thought this would be a good idea in Swift? Sometimes I hear the compiler's thoughts as it comes across this:
1. The dev explicitly told me this value would be optional.
2. I have a record from the database, and I see a 'nil' in the column for this value.
3. That's not "None" , Oh my god, I need there to be an explicit "None<CustomType>".
4. Shit shit shit shit. Oh my god.
5. PANIC!4 -

okay, well, maybe if we continue make from there it'll fix itself? Might've run out of RAM...

Compile and debug program, no local variables show.
Clean project, debug program, build errors.
Thanks Mr. Compiler -
Wish the Objective-C compiler had better type checking. There's no reason for it to not error out when I'm migration a property from one type to another.

Java is to JavaScript as car is to carpet, but check this out: https://developer.mozilla.org/en-US.... Rhino is a JS -> JVM bytecode compiler. That’s pretty neat!1
-
`Not really a function, but inserting a ${variable} like this is so convenient in JS.`
Closure Compiler will make it IE proof at the end, but I like having nice code in development. -
A compiler and assembler set for bootstrapping the whole gcc Code tree and cross compiling each level1

The compiler is like a math teacher marking your script except you don't get to pass and proceed until you get a perfect score.1
-
Wait, I HAVE to use double quotes when referring to RiotJS tags within JS, otherwise the in-browser compiler just spits out errors? FU
-
At work we are currently planing to migrate our source code to the latest compiler version. But I don’t think that we will migrate everything from the old version to the new version this time. Then we have to use three different compiler versions at the same time, with three different IDE versions. And how many VMs are you using at work?
-
Learned to program by shutting myself in my dorm room with a Shareware Modula-2 compiler and a well-written tutorial.
-
What are my odds that V8 will recognize my efforts and convert my for loop to use SIMD? It literally just adds the elements of a Float32Array to another, it's the single best chance for compiler optimizations to shine.3

Theres a kid competicion on infocmatics, I will take part of. I have built a compiler, and wanted to have an eye catcher for my project-presentationstable. Any good Ideas? IT schould be understandable by non-tech people3

My programming class kinda sucked. Here's why.
1. They taught C++. To students who had never seen a line of code in their lives. The language with 90+ keywords.
2. The teacher. We had to use switch statements to do something. It took around 300 loc. I used an array and shortened it to 5. He took some points away for not doing it correct. IT LITERALLY WORKS THE SAME AND IS SHORTER. This was not the first time I had shortened something/made it more readable and been docked points on the assignment.
3. Commenting. He told us to comment as much as possible, which is not correct. Comment what needs commenting. Not everything.
4. The compiler. We worked on windows with an online compiler. He decided teaching us to set up a compiler was too hard. We used onlinegdb, which isn't inherently bad. However, onlinegdb is based on Linux. He compiled our programs with a windows compiler.
Maybe these are just problems because I've programmed before that, but I still think they are red flags. What do you think?2 -
What the ****? I added a call to one method, how the hell it could broke it so badly?
> Compile failed with 1163 errors; see the compiler error output for details.1 -
Note to self:
Variadic C++ templates combined with obfuscated combinations of stl containers put you on the right path to be a "compiler message decryption" archmage.
Especially when you use MSCV... -

Today my 16 yr old cousin asked
me...
"If the compiler knows that..
"semicolon is missing at line no 16
in Helloworld.java", then why it can't
simply put a';' there instead of
telling us..."
He got a point.3 -
The more I think about the more it makes sense. If you're running a tracing jit compiler for a language with TCO does that means tail recursive functions are like asking to get traced?

I once made a minimal basic compiler in JavaScript. Inspired by shiffman's work to make a logo compiler in js .

If you're into compilers AND AI, check out Glow Compiler.
https://arxiv.org/pdf/...
Explains the idea well, casual read, almost no math just clean code examples and lots of easy reading explaining the ideas and theory behind it.
You can find the project at https://github.com/pytorch/glow and and also https://ai.facebook.com/tools/glow/1 -
I just created a new_file.rb in a crystal project and didn't notice until the compiler complained. I probably offended the compiler.

Do only developers have to do such tasks like Cinderella sorting out the lentils from the ashes?
Poor co-workers
* who had to program against the undocumented closed, ever changing API from Exchange Server, supporting over a decade old versions
* who had to compile a c++11 compatible clang or gcc on some sick old OS and almost got it working with compiling a fresher gcc with one that got stuck in one of the build stages. -
When I copy some lines of my source code into other functions but getting desperated when compiler says something like "...'Double' but 'Array' was expected" because I forgot to change the value for the functions.

Ah, it's that kind of Friday -
Agrrr... I hate to do code review of that shit! I hate to write docs for that shit! I hate to talk to PM! I hate dumb developers!
But there are several things about programming that make me calm and happy. When I'm thinking about one of those things I just sit and smile.
One such a thing is the process of upgrading gcc from sources.
1. Build new gcc with old gcc.
2. Build new gcc again with newly built gcc. Call this build A.
3. Build new gcc once more with build A. Call this build B.
4. Compare that A and B are exactly identical to the last bit.
5. You now have self reproducing compiler.
That is just beautiful and literally gives me chills. -
What is your favorite programming language to implement algorithms and data structure?
Or to be more specific, if you write interpreter and compiler, what is your choice of tool?5 -
Just seen F# and really like it. Sadly its compiler throws all kinds of errors on Linux with Mono because for some stupid reason it uses the Mono 2.0 DLLs...
