    `rx` is a modern and minimalist pixel editor.

  Designed with great care and love
    with pixel artists and animators in mind.

OVERVIEW

  `rx` is an extensible, modern and minimalist pixel editor implemented
  in rust[0]. rx is free software, licensed under the GPLv3.

  Most of the information on how to use rx is on the website:
  https://rx.cloudhead.io. There, you can also find a user guide
  (https://rx.cloudhead.io/guide.html), installation instructions,
  and binary download links.

  For discussions, join the community: https://rx.cloudhead.io/#community.

  To build rx from source, see the build sections below.

  Once inside rx, enter the `:help` command to get a list of key bindings
  and commands.

REQUIREMENTS

  At a minimum, OpenGL 3.3 support is required.

BUILD DEPENDENCIES

  * rust (https://www.rust-lang.org/tools/install)
  * cmake (https://cmake.org/download/)

  On macOS, `Xcode` and the `Xcode Command Line Tools` are required.
  The latter can be obtained by running `xcode-select --install`
  CMake can be installed with `brew install cmake`.

BUILD & INSTALLATION

  Before proceeding, make sure the BUILD DEPENDENCIES have been installed.

  Then, clone this repository and from its root, run:

    $ cargo install --locked --path .

  This will install rx under `~/.cargo/bin/rx`.  If you prefer a different
  install location, you can specify it via the `--root <prefix>` flag, where
  <prefix> is for example '/usr/local'.

CONTRIBUTING

  See the CONTRIBUTING file for details. Contributions are appreciated.

USAGE

  See the guide at https://rx.cloudhead.io/guide.html.

TROUBLESHOOTING

  If something isn't working like it's supposed to, there are various things
  you can do to debug the problem:

  * Run `rx` with verbose logging, by using the `-v` command-line flag. This
    will log errors from the underlying libraries that are usually suppressed,
    and will show debug output that might indicate what the problem is.
  * If `rx` is crashing, run it with `RUST_BACKTRACE=1` set in your environment
    to show a backtrace on crash.
  * It could be that the issue is related to your configuration - in that case
    the program can be run without loading the initialization script like so:

        rx -u -

Modifier keys + different keyboard layouts causing issues with keymappings

Related to #18

Windows 10, compiled with 1.38 stable. (--vulkan feature flag)

rx does not go into command mode when writing : using a Swedish/Nordic keyboard layout (Shift + Period) and instead zooms in one level.

It seems to recieve a colon in the RecievedCharacter event, but the KeyboardInput contains a period.

Logs:

[Suggestion] Create a makefile to simplify installation process

Adding a makefile would significantly simplify the installation process, and also make it easier to automate for packaging purposes. I'll gladly submit a PR with one if requested.

Super neat software, by the way :)

[1]    2243857 illegal hardware instruction (core dumped)  rx

System:
ArchLinux on Linux 5.4.0
Intel Corporation UHD Graphics 620 (rev 07)
sway version 1.2

seems like I can't hold down the keyboard keys to scroll across frames. this makes it super tough to nav between frames when fixing mistakes. also a short cut to choose frames as a focus would be nice as when I zoom, it moves to the center axis for some reason?

Image corruption after resize

I'm seeing a curious corruption issue after resize on latest master (19a5db2).

Steps to reproduce:

Start rx - canvas size will be 128x128x1
Add at least 3 frames (minimum 4 total frames, 3 or less won't trigger the issue for me)
Run command :f/resize 20 20
Delete all additional frames (hit backspace 3 or more times)

Not sure whether the size of 20 has any special meaning. I can consistently reproduce the issue with 20; 33, 48, 64 didn't trigger it; 10, 21, 32 triggered it only some times.

I attached a short screencast. Best viewed at full resolution as the gif is heavily dithered 😄

name conflicts with rx

rx is already a well-known name ("receive-xmodem") as as such conflicts with the package when installed.

Consider changing the name to something that isn't currently conflicting, such as 'vx' or 'px'

Non-Qwerty keyboards broken with current defaults

I figured out that I need to enable the winit feature to get proper key mappings on my non-qwerty keyboard.
Maybe this should be documented, or enabled by default.

Specifying a file to open at the command line forces zoom to 100%

I'm running a copy of rx installed with cargo install --git https://github.com/cloudhead/rx --tag v0.4.0 on Kubuntu Linux 16.04 LTS (64-bit) and I observe the following undesirable behaviour.

With the following in .rxrc in the current directory...

-- Set Cavernas tile size
f/resize 8 8
zoom 8.0

-- Work around the apparent inability to display "actual in-game size" and
-- "preferred editing size" simultaneously
map / :zoom 4.0
map m :zoom 16.0

-- Remap Enter to clone the last frame rather than inserting a blank one
map <return> :f/clone

-- Set Cavernas palette
p/clear
p/add #3e3d4c
p/add #5a5a63
p/add #847f7f
p/add #bcb19f
p/add #21263f
p/add #394071

p/add #c0461f
p/add #6c4f40
p/add #a5845a
p/add #cead73
p/add #673347

Running rx works as expected
Running rx player.png obeys every command in .rxrc except the zoom 8.0 (whether or not player.png exists).

(Which suggests to me that specifying a file on the command line is causing it do something equivalent to injecting a zoom 1.0 after evaluating .rxrc.)

rx: unknown tool "sampler"

Version: v0.2.0 8b2d7ba

Steps to reproduce

Remove config (~/.config/rx/init.rx);
Start rx.

Result

rx doesn't start with following error message:

rx: unknown tool "sampler"

Workaround

It seems that problem is that rx generates invalid init.rx which contains following line:

map/n  <ctrl>        :tool sampler {:tool -}                   --  Sample color (hold)

Removing this line from init.rx fixes problem.

Gif export seems to only export colors in the current palette

Issue: When exporting as a gif, it seems that colors which aren't part of the palette end up not being in the final gif. Those pixels end up transparent or simply the wrong color.

How to reproduce: Open a png file with rx file.png where file.png is an image containing colors that aren't in the starting palette. Split into multiple frames, then export as a gif. Switch to a palette with the required colors, then export as a second gif. The first gif has missing colors, but the second gif is correct.

debug does not play nice with checker

I noticed some strange behavior today when checker and deubg are both enabled.

Steps to reproduce:
1️⃣ Set checker = true and debug = true in your init.rx (or similar) config file. You can also set these in a running session.
2️⃣ Open rx.
3️⃣ Using the arrow keys navigate up and down.
🔳 Notice that the edit window and checker patterns go in opposite directions.

I can take a look at this when I get a chance. If you have any pointers on where the problem/fix might be I would appreciate the direction.

Is there any reason to hand-unwraping paths instead of using `fs::canonicalize`

I have tried to use ~, .. in paths and rx is failing to parse those. Also, I suppose it may fail with symlinks also.

rx/src/parser.rs

Line 218 in 75a11ff

if cfg!(unix) && path.starts_with("~") {

There is canonicalize function that should be able to resolve paths more reliably.

Rx shows black screen on i3

I installed rx with --features vulkan. After start, I get:

[2019-10-01T17:19:38Z WARN  rx::platform::backend] glfw: content scale isn't uniform: 0.7791411 x 0.7807377

The only thing I see is a black screen that I can't interact with (the -vv log is on pastebin).

I tried to interact with Rx nonetheless, following ReadMe instructions in hope that I'll be able to save a file to test if it works, but I get OutOfMemory before I get chance to do :w test.png.

I use i3, dual GPU intel/nvidia. Installed vulkan packages are

vulkan-icd-loader 1.1.121-1
vulkan-mesa-layer 19.1.7-1

Do you have any idea how to work around this?

Can it output to apng or only gif?

vsync disabled results in OoM

Runs fine if I enable vsync.
This seems similar to other issues I have encountered on nvidia GPU's where there is no delay when vsync is disabled so it renders and queues frames way too fast until it ooms.
Quite possibly an issue with wgpu instead of rx, but I haven't investigated it at all.

Occurs on:
OS: Arch Linux
GPU: GTX 960
Driver: Nvidia proprietary driver, version 418
Backend: Vulkan

The validation errors repeat many times before hitting the panic, I omitted most of them.

Release bindings for modifier keys are ignored in some cases

Under some conditions (apparently only when entering command line mode) release bindings for modifier keys (ctrl, shift) are not run. This results in the sampler tool remaining active or the brush remaining stuck in multi-mode (which could lead to damage or wasted work when the view is zoomed in on a single frame).

To reproduce (combinations given for my qwerty it layout):

Slice image or add some frames;
Type a colon (<shift>+.); exit the command line, multibrush will be active. Press and release <shift> to deactivate.
Type a colon with <ctrl> pressed (<ctrl>+<shift>+.); exit the command line, sampler tool will be active. Press b to bring back the brush. Pressing and releasing <ctrl> won't help because sampler/off reverts to the previous tool which right now is the sampler itself.

When loading config options from ~/.config/rx/init.rx I'm getting the following errors:

Not every setting triggers this crash, but these do:

Seems like any command that calls self.active_view_mut() triggers the crash. Maybe the active view needs to be initialized before config files are loaded?

Without those config options set rx starts and runs well.

I'd love to contribute to the project. If I could get some direction on what changes should be made and where to make them I'd be more than happy to put together a pull request.

System details:

Linux/Fedora 30 with Wayland
rustc 1.42.0-nightly (3a3f4a7cb 2019-12-28)

Let me know if you need more system deets.

How to run on non-Vulkan systems?

Framebuffer size is incorrect on Linux with HiDPI display

I've created a new issue so we could figure this one out on here. Could you remind me which line I should edit to better test the cursor positioning bug. I use a wacom intuos 3 tablet btw.

Issue

When I move over the canvas with the wacom pencil, there is an offset from the screen position, and the canvas position.

[Request] Background color

I might have missed it in the help menu, but it would be great to be able to change the background color of the window to something other than black - trying to draw black/dark sprites

Frame cloning and sync editing

Full copying and pasting ability would be very useful ofc and I'm sure it's on the roadmap, but in the meantime two features would help a lot with the animation process:

Frame cloning: add a new frame at the end (or even in the middle) with contents copied from another frame. Maybe a f/clone command with frame index?
Synchronous editing: propagate edits in a single frame to one or more other frames.

Maybe I can add the features myself and open some PRs if you like the idea? Let me know.
Thank you for building and sharing this project, looks really promising and it's pleasing to use.

Bug: Cannot open existing files

I can open new files just fine but when I try to open an existing .png file rx pops open a window and then crashes.

I'm digging into this but I'm not making much progress. I'll gladly try to fix it if you give me some hints on where the solution might go 😉

Error sourcing `palettes/sweetie16.palette`: "palettes/sweetie16.palette" not found

Something seems missing after cargo install.

Probably some basic palette should be embedded into executable with include_bytes!() or whatever to make it self-sufficient.

Alternatively (maybe better), entire config from git may be zipped and embedded into rx executable and unpacked on first start if $XDG_CONFIG_HOME/rx is missing.

Painting with keyboard

It would be great if a user could control brush with keyboard, instead of frame. Maybe it could be done in modal fashion like vim. Right now it doesn't make sense to use hjkl when you need to use mouse at the same time.

Also it would be great if you could map specific keybindings for creating specific patterns, maybe through scripting language or just with libraries of images.

Add `rustyline` or something to do tab-completion for command mode?

Basically what the topic says. Would be nice to have some autocomplete functionality, command history, etc. for the command mode. Thanks!

Tests

parser.rs: the parser should be property tested with something like quickcheck
cmd.rs: CommandLine should be tested with ascii and utf8
resources.rs: Gif export should be tested
session.rs: inputs (mouse, keyboard) should be fuzz-tested to ensure nothing can crash the program.
session.rs: selection/* commands should be tested in headless mode
session.rs: all commands that take user input should be tested with unexpected inputs to ensure there is no division by zero for example
lib.rs: rx's entry point should be tested with different inputs
Test that everything that modifies a view sets the [modified] flag on it

Report an input bug this has already been fixed in the master branch

I was going to report that I cannot use ctrl key to toggle the sampler, in my windows pc (gnu-toolchain).

After I browsed through the recent commits, it seems like something has been done to solve this problem (like 73f26c2). And I have tested the master branch build, it works.

I am opening this issue to document that this issue happened in the v0.4 version but solved in the master branch.

Thanks for the great work!

Edit: nevermind, it has been reported in #66

Build doesn't work

Got it - nvm.

macOS fullscreen laggy

When going fullscreen on macOS moving the cursor becomes super slow. Weirdly this issue doesn't happen while screen recording is happening via QuickTime : D

Proof.

Missing deps for debian/ubuntu cargo install

The cargo install documentation is missing the following packages for debian/ubuntu systems:

build-essential
libxcursor-dev
libxi-dev

I needed to install the latter two to compile the x11 dependencies in addition to the others in the docs, and I'm guessing you need the first.

Error when installing for mac

Tried to install it for mac following the instructions for mac. Got an error that I had to install cmake. Was able to resolve it by brew install cmake. Don't know if you can make that part of your dependencies.

But other then that was pretty easy to install and fun to play around with.

Oh and your help is missing the command to mirror things when painting.

Request: Support cmd+q on macOS

macOS 0.3 zipped Release won't open on Catalina

Hi! This is a pretty cool project and I was gonna test it out and ran into this:

I downloaded https://github.com/cloudhead/rx/releases/download/v0.3.0/rx-0.3.0-x86_64.app.zip as found on https://rx.cloudhead.io/.

I tried right click->open as well as just regularly double clicking but got the following error.

Command line ignores Home/End

While trying to figure out the best animation speed by eye, I discovered that, after using the up arrow in rx 0.4.0 to pull the set command back out of the command history, Home/End had no effect and I was forced to wait on the right arrow to get me to the value I wanted to tweak.

"gl" feature seems to be missing.

thread 'main' panicked at 'No adapters found. Please enable the feature for one of the graphics backends: vulkan, metal, dx12, dx11, gl', src/libcore/option.rs:1166:5

"gl"

cargo install --force --git https://github.com/cloudhead/rx --locked --features gl

Package rx v0.1.0 (https://github.com/cloudhead/rx#465f95f4)` does not have these features: `gl``
