Hi,
How to use image in this package, because the image not load. I'm use vuejs.
can you put image in gotron's example?

Behaviour:

⋊> go run .
Loaded Configuration:
server:127.0.0.1
port:9109
name:Gotron

2018/10/29 15:12:02 fork/exec ./app/node_modules/electron/dist/electron: no such file or directory
exit status 1

Only Electron.app in the dist/ directory:

⋊> ls app/node_modules/electron/dist/
Electron.app           LICENSES.chromium.html
LICENSE                version

• macOS 10.11.6
• gotron 7c479e1 (2018-10-09)

I am using gotron in Windows10. My app run smoothly. So, I packed my app by gotron-builder.

I put the executable somewhere in the PATH. However it return

npm WARN saveError ENOENT: no such file or directory, open 'C:\Users\user\package.json'

Hey

Been testing the example and the function

ws.onmessage = function(e) {
console.log("Message received: " + e.data);
}

will not be called in my javascript file. I can not see the mistake?

Hello
I can send strings, booleans, ints or another value or variable to backend?
I use the events but I don't understand what is the method to send values, I only can run a code whit a event but without a value from the Frontend

Example:
I create a form, the form get Username and password

When click "Send" with a event to backend, the event run the code but don't send the values to golang

How I compare this values with the values in the backend?

Or how i can send the values?

Thanks! :D

This is more a question. I've look into the examples using reactjs but im a bit confused on how to replicate an actual project using it. It looks like you have 2 package.json files one at the root and one inside each ui folder. Would be nice if this can be run independently or maybe im not understanding the setup correctly.
Thanks lots

Applause for including a screenshot of a demo app, however It would be great to see apps that are using Gotron currently in a production setting if they exist, or a section/link to attract those who may want to submit their app to be featured as one using Gotron.

I started to play with gotron yesterday, it is annoying fact that we need to construct a struct in order to start listening to an event.

window.On(&gotron.Event{Event: "event-name"}, func(bin []byte) {
	//Handle event here
}

It will be such cleaner API, if On method can accept String param as following:

window.On("event-name", func(bin []byte) {
	//Handle event here
}

Hi,

Sorry one more thing!!!

I am trying to build the sample app for windows. And I get checksum mismatch first

go: verifying github.com/otiai10/[email protected]: checksum mismatch
	downloaded: h1:A7kMXwDPBTfIVRv2l6XV3U6Su3SzLUzZjxnDDQVZDIY=
	go.sum:     h1:QJNFh2XEtzwESNsblZgBuCsv38DU5vC/u+5DNBekwJM=

Do you have any idea how to tackle this?

BTW, go version = 1.11 & OS = Mojave 10.14.2

Hi

Working on MacBook pro.
Both go build and gotron-builder work properly for the same platform.
Cross-compiling the go app with go build (GOOS=windows etc...) works.

gotron-builder --win fails with the following error:

I was wondering how this project was communicating with electron without any javascript conversion.

Hi

A new problem was just found using Goland IDE on Mac with Gotron.
When running the application I get this panic message:

chmod .gotron/assets: operation not permitted:

.gotron and .gotron/assets both have 777 permissions.

What can I do about this issue?

Thanks

Hi

As written in the getting-started guide, I run my gotron app and all modules are synched and downloaded. But on runtime it panics here:

done, err := window.Start()
if err != nil {
    panic(err)
}

with this line:
panic: : : fork/exec /Users/myself/Projects/domain.com/projectname/.gotron/node_modules/.bin/electron: no such file or directory

I have node and npm installed and available, and also go 1.12 with modules enabled.
What do I miss?

In case someone else runs into the issue, on Arch the example project wouldn't build giving:

error while loading shared libraries: libgconf-2.so.4: cannot open shared object file: No such file or directory

The fix is to install lib32-gconf.

# github.com/Equanox/gotron

above is the error I get when I execute the normal code copied from README.MD. BTW, my go version is go version go1.8.3 darwin/amd64

I tried to resolve the issue by changing line ending in git config, however it did not help

Hi There,

Looks like copy.Perm doesn't exist in the module github.com/puengel/copy. The following error is printed out during compilation:

github.com/Equanox/gotron

../github.com/Equanox/gotron/gotron_methods.go:122:9: undefined: copy.Perm

However copy.Copy works ok:

if firstRun || forceInstall {
templateDir := filepath.Join(gbwDirectory, templateApplicationDir)
//err = copy.Perm(templateDir, gbw.AppDirectory, 0777, 0644)
err = copy.Copy(templateDir, gbw.AppDirectory)
errz.Fatal(err)
}

cheers.

Does gotron support file actions (e.g., drag and drop, ...)? If yes, do you have an example somewhere?
Thanks for the nice lib!

I am trying to run
$ go run main.go because $ go run . does not work

Anyway I am getting compilation error from Golang:

# command-line-arguments
./main.go:124:21: undefined: FrontendPath

This is coming from that line in main.go:

//Conditional compilatiion for dev and prod
	path, exe, args := FrontendPath()

Any suggestions why ?

Is this project still going on ，this is of great help to my work .

First congratulations for the initiative!

When I using the command go mod tidy the package github.com/puengel/copy has a breaking on this repository. The github link for this repository don't exist.

Hi

Is there any way to change the application Icon instead of the default "Electron"?
Thanks!

I'm currently trying to work through this but currently hitting:

Uncaught TypeError: Cannot set property 'render' of undefined

Being newer to frontend development, I'm not sure what you would need from me to debug this. Happy to post anything you might need.

I tried running example on ubuntu 19.04 but hang up electron process after about 10 seconds.

There hasn't been any commits in multiple months. Is this the roadmap still correct?

Issue

I'm using godep for installing dependency, including gotron.
At the beginning, I configured Gopkg.toml like:

[prune]
  go-tests = true
  unused-packages = true

[[constraint]]
  name = "github.com/Equanox/gotron"
  branch = "master"

This config file causes the error: my/project/vendor/github.com/Equanox/gotron/templates/app: no such file or directory because templates/ folder in this project does not contain any *.go files and godep prunes such subfolders.

$ ls -la vendor/github.com/Equanox/gotron/

Solution

I had to add these lines to Gopkg.toml, to download the template/app folder and other non-go folders.

[prune]
  go-tests = true
  unused-packages = true

+  [[prune.project]]
+    name = "github.com/Equanox/gotron"
+    unused-packages = false
+

[[constraint]]
  name = "github.com/Equanox/gotron"
  branch = "master"

golang/dep#1890 (comment)

I think this is a godep specific issue, but creating issue within gotron repository may help someone who also encountered this problem.

When we run gotron-builder on Mac, we get a folder containing a Unix executable file with the name of our app and subfolder called electronjs which contains an Application file called gotron-browser-window. We can run the executable file to start the application locally, but if we try to copy it to another machine without the accompanying gotron-browser-window Application file, it will not run.

We would like the output to be a portable Application file that we could copy to any Mac and run independently. How can we achieve this?

Note: When we attempt to build for windows, we have a similar issue.

I got a permission denied error at the start of creating files in the directory .gotron.
Turns out the .gotron directory, and every subdirectory, is created with permissions of 555 instead of 755.

EDIT
My umask is 0022.

After go build delete gotron module from $GOPATH/pkg/github/Equanox/gotron/. Executable will fail with error since template folder does not exist anymore.

Need to copy templates to build dir or into build executable...

gotron-builder-amd64-darwin app=ui/dist

I get

FTL home/equa/repos/gotron/cmd/gotron-builder/main.go:64 > : : fork/exec node_modules/.bin/electron-builder: no such file or directory: fork/exec node_modules/.bin/electron-builder: no such file or directory: : fork/exec node_modules/.bin/electron-builder: no such file or directory: fork/exec node_modules/.bin/electron-builder: no such file or directory

My project looks like this:

main.go
node_modules
package.json
ui
   src
   dist

If I run gotron-builder-amd64-darwin to get the default build it throws the same error?

I guess I missed a step during set up. Any ideas?
