- Take a look as we begin working on a compiler. In a few hours, we get a basic, efficient lexer up and running, and begin to mock out the parsing stage. This is the start of a long compiler design playlist -- Watch live at / lens_r

i liked the brainstorming and how you think out loud with us
Well, there goes my weekend! I'll be following this avidly to see where it goes. Love the live coding, it's bringing back my memories of C, pointers and all the rest of it. Thanks for taking the time to post to RUclips, this lower level stuff keeps my interest in programming alive. I'd really enjoy seeing your compiler output the x86/64 assembly, but let's see... :)
The most impressive thing on this video is how this guy can hold his will of overengineer or overthink something. If it was me doing this live, I would be wondering how to implement automatic semicolon insertion without even deciding if the language would use semicolons to begin with.
Damn, RUclips recommendations be too accurate. Been thinking about doing something like this for a while. Will follow this series. Thanks
This might be quite useful!
I'm currently also making a compiler in C and thus far the hardest part has been deciding on a good data structure to hold types.
First video of yours I watch.
Your video style looks like a mix of tsoding and kling lol.
I'm definitely gonna binge this series.
I can't believe I watched three hours without skipping
I did not feel bored, I hope that you will explain the C language, because the way you explain is wonderful
I am not a native English speaker. I am from an Arab country. If you see any wrong word or my sentence is incorrect, I apologize for that.
No need to apologize! Your English is much better than my Arabic :p
I'm so glad you enjoyed!!
If you have any specific questions, the discord is always available 👍
@@Lensr In the last video, your pronunciation of the Arabic letters was correct👍
The fact that it took you so long to properly get the file size was painful because it took me just as long and you remonded me of that horrible time 😂😂
thumbs up just for the intro .. anyway really informative video.. really shed some light on how to construct compiler
I'm really glad you enjoyed! Thanks for watching :^)
Awesome! Im following along in Assembly.
how's it going?
I am following your video, to make my first compiler(first project in c). Somewhere you said don't do copy pasta, but idk from where to begin with, so i thought i should watch your stream, i am learning a lot. after watching you make it, i will make sure after this i will make my own compiler.
I may not be working on a compiler anytime soon, but this video inspired this CS student to chip at a first toy JSON parser in C (WIP). Funky thing is, I learned the hard way that circular references with header guards cause a mess of undefined typedefs... but that's another story. Thank you for the video, just subbed. 👍
Update: it finally parses nested structures, yay!
77:23 - as I read somewhere many many years ago: My biggest Perl mistake was trying to learn Perl. Now I am punishing myself for this horrid mistake by trying to learn Perl.
thank you for making this video
Thank you sir for providing this tutorial I will like you to continue please
great content ma man, it shows how much ur enjoying this.
I really like to create compilers even though I've never had created one LOL
Which program is used in 0:16 as replacement for the "ls" command? I have seen some options, but none seem to have this table formatting...
That’s just nushell, built into it
Why would RUclips reccomend me this one? Hmm... Anyway, thank you very much for this video! Looks very professional lol
Not sure, haha. The algorithm giveth and the algorithm taketh away 🤣
Either way, hope you enjoy :P
Have you made a similar series using C++? If so, I think that'd be really cool. Also, I'd like to recommend D to you. D's a low level language as well, but with a GC. However, D's GC has been optimized fantastically to the point where it virtually makes no noticeable impact. It offers many things that as a long(er) time C++ programmer, I've began to move over to D. I have not seen very many posts (videos or writeups) on people who've documented compiler dev with D from scratch, although that is a heavy usage of D. I think if you looked into D, you'd see many similarities with C, and conveniences C++ does not offer.
5:04 are you really? Here flying with vim airlines since 1990. Favorite animal: Bison. Flex ad eternum
I think I’m a bit late, but I really love your contents ❤❤❤❤
Really the best 👨🏫📓tutorial
Can you please indicate what program you install onto Windows to make it respond to linux commands (i.e.: ls, mkdir), also it lists files into a headed table. That would be a lot helpful.
Advanced thanks.
I already am aware about git bash for windows, but that does not list files into a table. So you must be using a different thing.
WSL
awesome👍🏻
Great video dude
Thank you!!
my compiler is called C2 because it is the second iteration of my Compiler xD
Now write a compiler in Moo
subscribing just for the intro zxdddddddddddd
cool stuff
I really appreciate it 🤟
You are a god.
Are you saying mygit or maggot?
you remind me of tsoding !
Bro Have me as your top fans, i demand that!
hi. i am late too party!! But will yu ever shift the code to LLVM . i.e using llvm to build this compiler (generating clang AST and then applying llvm middleend opt/maybe write your own)?
How did you make your windows terminal look like that?
Nushell + Windows Terminal
@@Lensr What settings do you use to make it look that way?
@@SkyDeathMKMT2 hes using emacs as a text editor if thats what you are asking about
what if c,python,go,lua in same compiler :D
now make a compiler IN scratch 😈
If you have a touch sreen and tap on the progress bar, not on the button. * | *

thank you so much great stuff but GOSH your'e code is dirtyyyyy
You can't spell "your"; I'm not worried about what idiots think.
I didn't really mean to offend you, I was just criticising have some capacity!@@Lensr
`typedef struct struct_name { ... } struct_name;`
can be written as.
`typedef struct { ... } struct_name;`
where `{ ... }` can be viewed as an "anonymous struct", saving a few key strokes and repetition.
I write it as typedef struct S { ... } S; because it's easier to use within debuggers.
@@xKaihatsu That is a very valid and useful way to keep using it. I did not see that.
Do you have a discord account?

Amazing content, but tell me: you complain about Microsoft so much, so why use Windows? Espicially since you seem to have a got an unix-like terminal thing going on, and you're using emacs.
voice too low. Had to wear those ugly earbuds
🤣🤣🤣
Emacs? Gross.
Here I read: skill issue
Professional Yapper. This entire thing could have been less than an hour if you didn't randomly start yapping about things not related to compilers. You should change the title so it's not misleading
It's a VOD, the point of the stream was to entertain the people watching it---not entitled assholes like you who feel so deserving of education for free that you leave embarrassing comments like this. You'll notice I don't stream anymore and a lot of it is because of people like you who are so unbelievably short-sighted and selfish. SMD, window-licker
@@Lensr You need to come back. You're an incredibly talented teacher and have a great personality. Just don't ever read the comments. You know you're on the right track by checking out the like to dislike ratio.
Hey man, I'm right now at 19:27 I'm following u in my windows machine, but I'm getting the following cmake error. Could you please help me out:
