Dramatic EDitor

THIS SOFTWARE IS UNFINISHED!!! Don't have any high expectations.

Quick Start

Dependencies

• SDL2 2.0.9+
• FreeType 2.13.0+
• GLEW 2.1.0+

POSIX

$ ./build.sh
$ ./ded src/main.c

Windows MSVC

> .\setup_dependencies.bat
> .\build_msvc.bat
> .\ded.exe src\main.c

Fonts

• Victor Mono: https://rubjo.github.io/victor-mono/
• Iosevka: https://github.com/be5invis/Iosevka

ded's Issues

it's not an issue, just a question

does this editor depends on the victor-mono fonts or it's not necessary?

plus i suggest to reduce the zoom when viewing big long files. however i really really like this editor for how cool it is :D

Suggestion: Reduce zoom levels once the text becomes big

Once the text file reaches something like 80 lines text starts becoming way too small and the intended effect reduces. I'd suggest making the zoom levels become fixed/capped at a certain point.

I tried to install on windows and got this message.

Updated DED crashed on Ubuntu 22

I recently built DED with the new changes (clipboard and runtime shader updates) but it crashes when I try to open a file or even the text editor itself.

The previous version worked like a charm. If anyone can help I would really appreciate it. Thanks to Tsoding for this wonderful project.

Hung on resize, now unkillable (WSL2)

Pretty sure I've not had a program hang this badly in at least 15 years but here we are.
Upon trying to maximize the window, the program started hanging.

Running killall ded closed all ded processes yet the program window is still there. Unwilling to be killed by Windows or Linux

mouse click is broken, because the coordinates need to be mapped differently

introduced in #17

The feature was initially introduced in #14

[RESOLVED with PR #42]#error: "TODO: type_of_file() is not implemented for Windows"

Line 136 in common.c doesn't allow build in Windows. Is there a type_of_file() function for Windows available?

msvc build not working

Tested on 0b7b6fd under windows 10, visual studio 2019.

If I run

setup_dependencies.bat
build_msvc.bat

And then If I run ded.exe from the command prompt I get the following error:

The code execution cannot proceed because SDL2.dll was not found. Reinstalling the program may fix this problem.

Failed to compile simple_color.frag on mac OS Ventura 13.2.1

I am not able to even launch the editor at the moment. I understand that it is not developed for mac OS but I thought I would add this in here just in case it can be fixed easily.
the error message I get when I try to run ./ded after running the ./build.sh is the following:

GL issues on macOS 11.7.2

Caveats

I don't write many graphical programs. Perhaps macOS is always a pain and you don't want to support it. Given that build.sh contains a uname check for "Darwin" though, I'm giving it a shot.

Problem

I installed the following versions of the dependencies (latest in Homebrew):

• sdl2 2.26.3
• freetype 2.13.0
• glew 2.2.0_1

The build went fine without warnings or errors.

Running the first build:

❯ ./ded
GL version 3.3
ARB_draw_instanced is not supported; game may not work properly!!

I added a YOLO environment variable to skip returning 1 for all those "game may not work properly" checks, to press on and see where I got.

❯ YOLO=1 ./ded
GL version 3.3
ARB_draw_instanced is not supported; game may not work properly!!
WARNING! GLEW_ARB_debug_output is not availableERROR: could not compile GL_FRAGMENT_SHADER
ERROR: 0:6: Use of undeclared identifier 'gl_FragColor'

ERROR: failed to compile `./shaders/simple_color.frag` shader file

Is the program written for a different GL version than what macOS 11.7.2 provides perhaps?

I edited each of the shaders/simple_*.frag programs to stop using gl_FragColor and instead declare out vec4 fragColor; and use that.

Solved?

It looks like everything is working for now, with two changes:

• make the "game may not work properly" warnings ignorable
• stop using gl_FragColor for shader output

How fix src/free_glyph.c:9:60: error: ‘FT_RENDER_MODE_SDF’ undeclared (first use in this function); did you mean ‘FT_RENDER_MODE_MAX’?

Execution Error:

I am trying to run the editor on my computer. I cloned the latest repo (7f3638d). Building with ./build.sh worked fine. However, when I run the executable I get the following Error:

Command:

./ded

Output

GL version 3.3
ERROR: could not load glyph of a character with code 32

For a fraction of a second a window pops up. It then closes with the error.

Is there a way I can fix this? I think it might have something to do with freetype since googling the error lead me in that direction.

introduced in #25

opengl can't compile the shader

GL version 3.3
GL CALLBACK: type = 0x8251, severity = 0x826b, message = Buffer detailed info: Buffer object 1 (bound to GL_ARRAY_BUFFER_ARB, usage hint is GL_STATIC_DRAW) will use VIDEO memory as the source for buffer object operations.

Better Name

We still didn't come up with the proper name. Leave your suggestions in the comments. The name should be short ('cause we don't wanna type too much in the terminal to start the editor) and memorable.

Misspelling

"not" is misspelled as "ont".

Problem Trying to Build with MSVC

After running .\setup_dependencies.bat . It says

Then when I run .\build_msvc.bat. I am getting this error.

I am new to adding and using libraries like this.
If anyone can help me with this. It would be helpful.
Thank You in advance.

dollar signs are rendered... interestingly...

Not sure what's happening here.
Haven't found any other character yet that renders like this.

./build_msvc.bat is not working

I tried #42 to build on Windows but I am getting LINK : fatal error LNK1181: Cannot open 'dependencies\freetype2\release.obj' error when I try to build.

How can I fix that is there a problem with ./build_msvc.bat ?

Rainbow effect

In the Youtube vidéo, when you start typing, the text start to do a rainbow/rgb color effect which is pretty cool. But when I start, even with the font installed, all I got is just white text. How can I get the rainbow effect ?

Can't go to the previous folder, in the file browser

.
..
<files>

when you try to visit the ../ directory, using the file browser, it fails, on the assertion:-
ded: src/common.c:102: read_entire_file: Assertion 'sb->items != NULL && "Buy more RAM lol"' failed.

The problem is that my machine has 8 gigs of ram, which should be enough for a minimal editor like this, but I could be wrong.
Does anyone know, if the issue regarding my machine, or ded?

ERROR: Could not initialize GLEW!

Hey,
I am trying to install ded on Debian.
I have all of the dependencies installed but when i try to run ./ded src/main.c i get:

Loading src/main.c
GL version 3.3
ERROR: Could not initialize GLEW!

`da_move` could lead to undesired side effects

ded/src/common.h

Lines 37 to 43 in 57d23fa

	#define da_move(dst, src) \
	do { \
	free((dst)->items); \
	(dst)->items = (src).items; \
	(dst)->count = (src).count; \
	(dst)->capacity = (src).capacity; \
	} while (0)

I think that we should "clear" src after moving it to dst (setting (src).items = NULL; and zeroing its count and capacity).

Since src still holds a pointer to items it could cause undesired side effects.

build.sh using CRLF line terminators

Shows it here:

The build.sh file didn't even show as executable beforehand because It wasn't the right file type, so I had to chmod +x build.sh. After fixing, out.sh worked without any changes. These issues are likely due to making the file with something that saved it to a DOS like format.
