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.

Firebase - update a spacific fields of single element of object of array in firestore

Firebase - update a spacific fields of single element of object of array in firestore  Its actully advisable to use map instead of array when ever it is possible. But, there are cetain cases where you don't have option to do so.  For example, you are directly saving the response from some outer source without any modification and they send you an array. In this case you will have array to work with. Firestore does not support array here is why  "bad things can happen if you have multiple clients all trying to update or delete array elements at specific indexes. In the past, Cloud Firestore addressed these issues by limiting what you can do with arrays " For more details information you can refer to Kato Richardson post Best Practices: Arrays in Firebase .  Firestore document having array [ used from stackoverflow question ] Suppose you have array of object something like shown in array. Now you want to update endTime field of the object on the index [1]
