Cuelang trimming

[lakshy-amagi]

I aim to trim down my JSON, add some customization to the input data, and provide the output data.

The way I have done this is
I create three files

1. input1.cue
2. input2.cue
3. cue_template.cue

and with the help of packages, I refer to the values from the input1.cue and input2.cue
and create output.cue

I integrate this in my go-code

func GetMaskedProgram(platformID string, pIDMap map[string]forms.JammerPlatformConfig, req forms.ProgramsReqBody, path string) forms.StdMetaInfo {

	/*	Get masked program  */

	/*
		* * Load the program schema
		program schema to masked the complete program
	*/

	c := cuecontext.New()

	// Load the program values from the values.cue file
	inst := load.Instances([]string{GetSchemaFileName(platformID, pIDMap, req, path)}, nil)
	/*
		* * Build the masked program
		Masked program in the cue format
	*/

	// Lock the mutex to ensure exclusive access during file read
	mu.Lock()
	program := c.BuildInstance(inst[0])
	if program.Err() != nil {
		// Fail to build the masked program
		logger.Error("Fail to build the masked program", program.Err().Error(), standardFields)
	}
	mu.Unlock()
	// Unlock the mutex to release the lock

	// Evaluate the program
	program = program.Value()
	/*
		* * Load masked program
		Masked program in the json format
	*/
	programJSON, err := program.MarshalJSON()
	if err != nil {
		// Fail to marshal the program cue values
		logger.Error("Fail to marshal the program cue values to json", err.Error())
	}

	// Unmarshal masked program
	var pgm forms.StdMetaInfo
	err = json.Unmarshal(programJSON, &pgm)
	if err != nil {
		logger.Error("Json unmarshal of programJSON failed", err, standardFields)
	}
	return pgm
}

Here this line
inst := load.Instances([]string{GetSchemaFileName(platformID, pIDMap, req, path)}, nil)

read the cue_template.cue
which is something like this -

package y

import "values:x"

import "values:z"

{
	program: {
		type:           x.Program.ContentType
		episode_number: x.Program.EpisodeNum
		info: [ for l, i in x.Program.ProgramInfo if z.Language == "" || z.Language == l {
			language_code: i.LanguageCode
			title:         i.Title
		}]
	}
}

input1.cue

package x

{
	Program: {
		ProgramUUID: "lionsgate_ep_2"
		ProgramInfo: {
			en: {
				Title:            "Lionsgate Episode 1"
				AlternativeTitle: ""
				LanguageCode:     "en"
				Genre: ["Cooking variety", "Food"]
				ShortDescription: "Host Matt Moore joins Chef Molly Martin at the grounds of Juniper Green on the West side of Nashville.

		GmsID: "https://compass.amagi.tv/gms/entity/APRkYqH2eQyZrj7j4gkWNUL"
		EpisodeNum: 1
		ContentType: "Episode"
	}
}

input2.cue

package z

{
	UINotEnabled:   false
	Type:           ""
	StartTime:      ""
	Search:         ""
	PlatformID:     "amgplt0020"
	PerPage:        ""
	Page:           ""
	MetadataErrors: false
	Language:       "en"
	Expanded:       true
	EndTime:        ""
	ChannelID:      "amg05113c1"
	AssetID:        "lionsgate_ep_2"
	AmgID:          "amg05113"
}

Is there any way where I don't need to create the files?
