GUI init

[ScherrerMichael]

Please try it out!

To run: do ./perf-rust gui

Please Note:

• Currently, tests and other programs are not implemented in the GUI. In order for them to work properly, programs will need to provide output in the form of a formatted string. If you would like to see where I plan to implement the perf events, check out the Loaded(state) function and the PerfEvent enums. I feel like once we figure this out, we can make graphics later!
• Loading and saving are not implemented yet. I figured it is more important to have base functionality first.
• The style is not final.

I would like to update this PR every time a perf event is added.

I pulled down this PR locally and tried building but got this error:

error: failed to run custom build command for `freetype-sys v0.13.1`

The build failed after that, did this happen to you at all?

[Boursler]

The PR builds fine for me and runs.

[Sl1mb0]

Ran into two somewhat easy hiccups, and a third which I am currently working on. Some things:

• cmake must be installed
• This issue gives a necessary command if the servo-fontconfig-sys crate fails to build.
• The third error message has to do with cc failing to link. This post on stack overflow describes the exact error message I got. And this github issue also references the same error message.

I'll let you guys know more when I get it working.

[Boursler]

Thanks. If it requires cmake, that helps me understand part of why it built for me as I have that program installed. Still if that's a dependency we should document it somewhere. Is the linker issue mac specific?

[Sl1mb0]

Nope! Used my Ubuntu machine.

[ScherrerMichael]

@Sl1mb0 let me know if you still are getting issues. I did remember getting something very similar to that, with the same error message. I'm going to look through it again and see what I did to fix it.

Thanks for recording that!

Edit: Have you tried installing these packages?

sudo apt install pkg-config libasound2-dev libssl-dev cmake libfreetype6-dev
libexpat1-dev libxcb-composite0-dev

source

[Sl1mb0]

I have built it successfully. In addition to the dependencies listed previously there are also these dependencies that I installed:

libgtk-3-dev
libx11-dev

source

Edit:

Not sure how we should address these issues for our our project, I just know that we should include something about these dependencies somewhere. I got this message when running target/debug/perf-rust gui:

INTEL-MESA: warning: Ivy Bridge Vulkan support is incomplete

But other than that it opened up fine. It looks awesome @ScherrerMichael, great job!

[Sl1mb0]

The only thing I would suggest is breaking up src/gui/mod.rs into separate, smaller, sub-modules so that navigating the gui module is easier.

Just spitballing, but you could maybe do something like this:

src/gui/state.rs
src/gui/content.rs
...

[ScherrerMichael]

Sounds good @Sl1mb0, and @Boursler. I was just thinking that too. I'll push out an update tonight with all of these suggestions in mind.

Cool!! This worked for me, but I'm pretty sure I had everything above already installed on my computer.
I like the layout, and seems to be a good system for showing the output of the program. Nice!

I did notice when resizing the window to be pretty small, the "Launch" button loses its text, but stays near the bottom of the pane and turns comically tiny-- maybe we could find out how to keep the button text when it shrinks.

Other than that, I don't love how everything is in mod.rs... a 500 line file is simply too long. I bet we could break it into a few different files.

This is so awesome! Great work on this and thank you!

[ScherrerMichael]

I separated the mod.rs into smaller parts as suggested by @Sl1mb0 & @kagutaba256. In addition I added main gui.rs file to the root directory as it follows current file structure guidelines. Will be working on resizing issues noted by @kagutaba256.

Thanks everyone!

[Boursler]

Looks great, thanks for doing this!
