How to run? about fidget

[treeform]

I have added the .nimble dependancies. I have tested it working on mac and windows.

There is still a ton of work todo.

[andreaferretti]

Then... I guess it should not be mentioned at all in the nimble file and the import should become import nimgl/glfw?

Anyway, I tried changing the nimble file by removing

requires "glfw >= 3.2.1"

and adding

requires "nimgl >= 1.0.1"

and changing src/fidget/openglbackend/base.nim like this

import nimgl/glfw
# import glfw3

and it still does not compile (Error: undeclared identifier: 'GetWindowSize').

Now, I understand that this is a project in development, so it's ok.

I am a little worried about the dependencies though. I guess Nimble should just forbid global installs (no more nimble install somelibrary) in favour of requires somelibrary, otherwise the Nim ecosystem is going to become quite brittle.

[treeform]

Sorry this project is not ready yet. I am still working on it.

I need to update nimble.

You just run the projects directly nim c -r ...yourfile...

fidgetgen was for some thing else..

[andreaferretti]

I understand that the project is not in shape right now. If you ever have the time, I think it would be worthwhile to actually include the dependencies (with working versions) in the nimble file. Right now, it is a hit and miss guessing which dependencies are needed, and I have not been able to compile any example

[andreaferretti]

Thank you! Now I understand the problem I had with the dependencies. Your nimble file declares

requires "glfw >= 3.2.1"

but the latest version published on https://github.com/ephja/nim-glfw is 0.3.1

Do you have access to a more up to date version of glfw?

[SolitudeSF]

@andreaferretti thats probably it https://github.com/nimgl/glfw
nimble file should point to git repo instead of just glfw

[andreaferretti]

Then maybe this should be published on nimble. On https://github.com/nim-lang/packages/blob/master/packages.json, glfw points to https://github.com/ephja/nim-glfw

[SolitudeSF]

it is published on nimble in form of https://github.com/nimgl/nimgl subpackage

[andreaferretti]

That is good to know, but what does it mean? On the README of Nimble, subpackages are not even mentioned

[SolitudeSF]

it means you import it with nimgl/glfw instead of just glfw. i mean a logical subpackage.

[treeform]

I am using https://github.com/rafaelvasco/nimrod-glfw/blob/master/glfw.nimble

packageName   = "glfw"
version       = "3.2.1"

I don't use https://github.com/nimgl/nimgl so that will not work.

[treeform]

I think the https://github.com/rafaelvasco/nimrod-glfw/blob/master/glfw.nimble is broken. It installs as requires "nimrod-glfw >= 3.2.1" but internally calls itself glfw and goes into a folder called glfw-3.2.1 but you import it as glfw3 ... its a mess?

[andreaferretti]

Well, a little mess, but less than I had feared! :-) Nimble suggests to use a module name equal to the package name, but this is not enforced (yet?).

So, it is just a matter of changing

requires "glfw >= 3.2.1"

to

requires "nimrod-glfw >= 3.2.1"

At least now I am able to compile! :-) Not that I see much, the text and inputs are still missing, but I guess that's just the status of the native backend

[treeform]

Sorry the text missing was caused by recent "Mac fix". I have fixed it again. Some of the examples should be showing up now. Added a section to the readme about which examples to run:

Now to run the examples:

Native examples for Windows, macOS, and Linux:

cd examples
nim c -r bars/bars.nim
nim c -r fonts/fonts.nim
nim c -r hovers/hovers.nim
nim c -r inputs/inputs.nim
nim c -r padoftext/padoftext.nim
nim c -r padofcode/padofcode.nim
nim c -r basic/basic.nim

Runs the same examples as HTML:

cd examples
nim js -o:bars/bars.js bars/bars.nim
nim js -o:fonts/fonts.js fonts/fonts.nim
nim js -o:hovers/hovers.js hovers/hovers.nim
nim js -o:inputs/inputs.js inputs/inputs.nim
nim js -o:padoftext/padoftext.js padoftext/padoftext.nim
nim js -o:padofcode/padofcode.js padofcode/padofcode.nim
nim js -o:basic/basic.js basic/basic.nim

[andreaferretti]

Great, thank you! Now all examples run for me as well! :-)

Hi guys,

I have added the changes to nimrod-glfw as noted above but I still get this error during compilation:

...\.nimble\pkgs\fidget-0.2.1\fidget\openglbackend\slate.nim(27, 33) Error: type mismatch: got <seq[uint8]>
but expected one of:
proc compress(input: string): string
  first type mismatch at position: 1
  required type for input: string
  but expression 'mip.data' is of type: seq[uint8]

expression: snappy.compress(mip.data)

I'm on Windows 10 with Nim Compiler Version 1.1.1 [Windows: amd64].

[treeform]

@matkuki it looks like you have the wrong snappy version? Make sure you have this one: https://github.com/treeform/snappy

It looks like the nimble's snappy is not mine? https://nimble.directory/pkg/snappy

I'll fix my .nimble file.

[treeform]

I have updated the nimble file see if it works for you now.

Also latest version of nim is 1.0.2 not 1.1.1! https://nim-lang.org/blog.html

[SolitudeSF]

1.1.1 is devel

[matkuki]

Yes, I did a fresh install a couple of days ago.

@treeform
I deleted my old snappy installation and tried your new nimble file, but I had to change the line:
requires "https://github.com/treeform/snappy@4c900cb0d979a2b8fc07835925d268319a6b1129"
to
requires "https://github.com/treeform/snappy"
otherwise I got an error when nimble wanted to download the repository.
But I still get the same error.

[andreaferretti]

The right incantation is
requires "https://github.com/treeform/snappy#4c900cb0d979a2b8fc07835925d268319a6b1129"

[matkuki]

@andreaferretti
Thanks, yes that fixes the snappy installation.
Just noticed that the nim js ... compilation works, but the nim c ... doesn't.
I guess it's not ready yet?

[treeform]

What issue do you get? It supposed to all work.

[matkuki]

Hey @treeform
As I showed above, it's the same error when compiling for example examples/basic/basic.nim with nim c basic.nim:

Hint: slate [Processing]
Hint: snappy [Processing]
...\.nimble\pkgs\fidget-0.2.1\fidget\openglbackend\slate.nim(27, 33) Error: type mismatch: got <seq[uint8]>
but expected one of:
proc compress(input: string): string
  first type mismatch at position: 1
  required type for input: string
  but expression 'mip.data' is of type: seq[uint8]

expression: snappy.compress(mip.data)

... but compiling with nim js basic.nim works.

[treeform]

I have fixed the nimble file can you try reinstalling this package (which should fix the dependencies) and see if it works for you?

[matkuki]

Hey @treeform
I removed fidget and reinstalled it with nimble install https://github.com/treeform/fidget and compiled the basic.nim with ˙nim c basic.nim˙ again and got the same error I think:

I also tried removing snappy and fidget (as snappy seems to be causing the problem), then reinstalled fidget, but the error persists.

[treeform]

Could you remove snappy? And run my installer again? So that it installs the right one.

I tried removing snappy again and reinstalling fidget with:

git clone https://github.com/treeform/fidget
cd fidget 
nimble install
cd examples/minimal
nim c -r minimal

But the installation always installs the same version of snappy:

The error is still there.

[treeform]

There is some thing strange going on with snappy. Its complaining about this signature:

proc compress(input: string): string

But its not part of https://github.com/jangko/snappy/blob/master/snappy.nim .

The signature there is:

template compress*(src: openArray[byte]): seq[byte] =

It looks like you are getting it from this snappy:
https://github.com/dfdeshom/nimsnappy

It claims to be nimsnappy but the file it provides is snappy.nim so it clashes with the other import.

Please uninstall that nimsnappy so that proper snappy can be found. Which is https://github.com/jangko/snappy/blob/master/snappy.nim version.

So can go into your ~/.nimble/pkg folder and make sure all things that look like "snappy" are gone.

[matkuki]

Yes, that did it! nimsnappy was the culprit!
Uninstalling snappy and nimsnappy and reinstalling fidget fixed the issue.

Thank you, @treeform !

I would close this issue, but I don't have the necessary rights.

[treeform]

Cool I am glad that worked!
