CudaText: Open-source, cross-platform text editor, written in Lazarus


Hmm, interesting genesis:

> When it was 2014 or 2015, we had some big events in Russia (Crimea related) so many people here were excited. I was too, so I wanted to program some new project.


So it started as a celebretion of the annexation of Crimea by Russia?


The CudaText author is here. No, I did not celebrate the Crimea 'annexation' (in local Ru talks, we cannot name it 'annexation', we must name it 'reunion'). But I was reading such big amount of news at that time, in 2014, that I was excited only from this wave of news. Many patriotic people in Rus were happy and welcomed that. Many opposition people in Rus were not happy and did not welcome that. But the wave of news was very big. For me the Crimea was not positive news. I never have been in Crimea. I never got the FREE ticket to rest in Crimea. The rest in Crimea is not cheep. In 2014 and in 2022. It costs big amount.


Yesterday was about to install CudaText, but as usually with such software, before jumping to anything started to read about your project and you and accidentally got to that quote mentioned above. I must admit, it got me spooked. I have a lot of respect to people who do contribute to open source so I do to you, but in current situation my concern is actually safety and trust.

For example I don't think I can give you a trust to binary packages, like in this case:

Even if they are not containing anything malicious at this moment, it can happen at any time later, especially after gaining a trust of significant amount of devs. And even with your best intentions I can clearly see a scenario where it will happen against your will or even without your knowledge. You know - it is different thing to trust you, and different thing to trust your state...

Anyway, hope this whole war madness (or "special operation" as you're allowed to call it) will end soon.


Any chance you can add code completion to python terminal? That would make cuda-text a super-editor on the level of vim and emacs but easier to use.

[uncomfortable silence]


The word you are referring to is "čuda" or equivalently in cyrilic "чуда" pronounced "chuda".


It could be, "With all the excitement going on, finding a nice programming project to distract me seemed like a good idea."


We need to make sure this isn’t the neutral-connotation usage of the word “excitement”.

A plane crashing into the neighbors house can be “exciting”.




Cool! I just learned about this editor randomly about a week ago [1], then mentioned it on the thread about Double Commander the other day, a file manager also written in Lazarus [2].

I'm just about to get it to compile. I'm writing a Python version of the Bash script that downloads and installs all of the packages. It's a learning project so it's pretty messy but I intend to clean it up and submit it to the developers at some point.

CudaText is nice, I'm using it to write this compiling script to get to know it better. It's sort of SublimeText-adjacent but also its own thing. I already have a long list of things I want to replicate from my Sublime setup.




The author is really responsive. I reached out about the ability to make snippets run external commands and place the output in the editor. Within a day I think he had implemented it as a plugin.

I use like 100+ of these snippets in Geany, so it was awesome to see it become a feature in another interesting new editor.


I had to change my editor every now and then in the last years, because something bothered me... the eternal search for the holy grail, so to speak. So Vim and Emacs have already fallen by the wayside. Now I'm actually stuck with CudaText. In my opinion the editor is really first class, I recommend to try it out.

For me, however, also very exciting is the realization that Lazarus/FreePascal programs generally always stand out very positively. The speed and memory efficiency is remarkable!



Uhm yeah, that is uh, quite, ah, reminiscent, yes.


What's with the CUDA reference?


It's from the Serbian word "čuda", which is pronounced "chuda". It means "miracles", and also occurs in many other Slavic languages (Russian "чуда", etc)


That got me wondering at a first glance too. But in this case, the word stands for "čuda" not CUDA.

Čuda = miracles, wonders, in Serbian (and several other languages).

And odd conglomerate of words from different languages perhaps, one even anglicized (ASCIIzed?) at that... Well, it does get the people talking, I suppose.


In trademark law, the owner of a mark (Nvidia in the case of CUDA) can usually make someone stop using a mark if it would lead to “consumer confusion about the source of the goods” (i.e. people seeing “CudaText” and assuming it has an association with Nvidia/CUDA).

IANAL, and have no idea how likely Nvidia would be to succeed in a trademark dispute with this developer. But in situations like this, it’s often good to just not use a name if a large section of your target audience could become confused upon hearing it. Even if you didn’t know about the other product when you came up with your name, and even if it’s technically legal.


Author of CudaText here. If I will get the complain from NVIDIA I can rename the project to 'CudeText', word 'cude' is 'miracle'. Now I think that similar name was a little mistake from my side, I needed to name it 'CudeText' earlier.


Perhaps it’s short for barracuda?


There's a note buried at the bottom of the page:

Disclaimer: word "cuda" is taken from Serbian language, it means "miracles".


Besides Lazarus itself, in my opinion after watching the video demo, this may be the best opensource software written in Lazarus/Freepascal.

Sad that I knew about this before but ignored it wrongly thinking CUDA had to do with GPUs.


The detailed list of features is here:

I did not know of this project, but it looks really good. It's nice to see projects developed in Lazarus!


Fantastic piece of software. I used it extensively under Ubuntu and Windows.

If they make it available through brew I will use it in MacOS too.

Another one ultrafast program Laz/Pas related was LazPaint.

At some point there was a NotePas too!


The amount of work put into this from single person seems astonishing. Per a forum post the author doesn't even care about the donation page working. I wonder how people get to this point in their life that they can spend all days just coding their oss projects for fun. It seems so out of reach for me.


You are exaggerating, I develop it for 6-7 years, and not every day is coding.


I thought this was going to tell me about a hardware accelerated text editor.


From 2020 interview:

SF: What is the next big thing for CudaText? AT: A mate of mine, young programmer Artem Gavrilov from Saint Petersburg, has suggested that editor rendering should be in OpenGL, and he has good experience in 3D graphics and Pascal. I am thinking now how this can be done, it’s a lot of coding even with ready OpenGL libraries. This will make scrolling in editor much smoother. And another idea: make configurable docked panels. CudaText has several panels (Code Tree, Project Manager, Console, Output, etc.) but they are locked in the side or bottom, no configuration, panel cannot be moved from side to bottom, no docking to the right. It’s not needed much but configurable panels are handy.


Ray tracing for your fonts!

There are multiple GPU-accelerated terminal emulators; I suppose, why not a text editor?


How does it compare to Sublime Text? This seems to be a FAQ but the link appears to be broken, and I didn't find a corresponding entry in the Wiki.


The proper wiki page - .

1- CudaText advantages over Sublime Text 3; 2- CudaText advantages over Visual Studio Code; 3- CudaText disadvantages compared to Sublime Text / VSCode.

Where did you get the broken link?


On the landing page there is a link to


Looks like there is no macos aarch64 version on the sourceforge binary download site? Just seeing amd64 (unless that download includes aarch64 compatibility)


It (macOS aarch64) will be there in some weeks, maybe in about 10 days. Older version -

macOS AArch64 version needs this to be run: xattr -cr /Applications/


Cool, thank you! Will be trying it out at work..
