Use packfolder to archive your resource




In commit 25d8ed42e0bb4c4acb742de9f148f6902d32ff41 go-sciter SDK has added one new facility which automatically resolves file path for archived data . Now you can use archived data from the archive and it will resolve import by itself, as it does for c & c++.


Packfolder

packfolder is utility provided as part sciter-sdk. It compresses resources folder under a single file of the format of your choice ( should support by packfolder ). Currently, supported output format files are bin ( normal binary file ) an array of bytes in c, go, d and rust language. 

Syntex is ,
[path]\packfolder.exe [resource-folder] [resource-file].[ext] -V [name-of-variable] -[output-format]

  • path = full / relative path to packfolder.exe to execute command
  • resource-folder = full/relative path to the folder inside which your resouce is contained
  • resource-file  = name of the file you want as your output file 
  • name-of-variable = it will the name of the varilble that will iniated with the array of bytes of your resource folder
  • output-format = format of your output file


Example 


[ ps stands for PowerShell - I'm using windows ]


unarchived res folder


Command 
PS:.\packfolder.exe res res.go -V resource -go

here  I've put packfolder.exe in the same folder as my project. [ ya, you can do that, after all, packfolder is standalone utitily . ] 

res is the folder which contians resource used in my app


Resource folder we want to compress


res.go is the file I am expecting to be generated on compress of the resource folder. 





-V stands for the variable name I want the variale name as resoruce so I  "-V resource"

and at last, i want output for the golang file. so -go
res.go file containing bytes of archived data


It will generate a syntactilly valid file of golang contiaing bytes of our archive. Upto this we have compressed our res folder in a single resource file. 



Load archived resource in your App using SetResourceArchive

SetResouceArchive function is responsible for loading the archived file at their relative paths.

func main() {
// make rect for window
rect := sciter.NewRect(100, 100, 300, 500)

// create a window using upper rect
win, _ := window.New(sciter.SW_MAIN|sciter.SW_CONTROLS|sciter.SW_RESIZEABLE, rect)


// SetResourceArchive expects array of bytes as input
// It does open the archive and also auto resolvs file
// file path 
// Here resoure is array of bytes that has been generated 
// by packfolder.exe 
win.SetResourceArchive(resources) 
win.LoadFile("this://app/htdocs/notepad.htm")

win.SetTitle("Notepad+-")

// registering methods
win.DefineFunction("closeWindow", closeApplication)
win.DefineFunction("save", save)
win.DefineFunction("open", open)

win.Show()
win.Run()
win.CloseArchive()
}


So now your resource are part of your gocode. There is no need to ship the resource folder any more. It also make your resource safe and hidden from outside.
