Types

type Applier

type Applier struct {
	// contains filtered or unexported fields
}

Applier applies changes to configurations using the evaluation system.

func NewApplier

func NewApplier(cfg *config.Config) *Applier

NewApplier creates a new change applier for the given configuration.

func (*Applier) ApplyChanges

func (a *Applier) ApplyChanges(filePath string, tags []string) ([]ChangeResult, error)

ApplyChanges applies all matching changes to a file context This is a simplified version - a full implementation would need to: - Parse YAML files - Apply fileSelector and keySelector matching - Modify the YAML documents - Write back the results .

func (*Applier) EvaluateChangeValue

func (a *Applier) EvaluateChangeValue(change config.ChangeOrder, filePath string) (string, error)

EvaluateChangeValue evaluates a change order's value in the context of a specific file.

func (*Applier) GetEvalContext

func (a *Applier) GetEvalContext() *EvalContext

GetEvalContext returns the evaluation context for this applier.

type ChangeResult

type ChangeResult struct {
	Change   config.ChangeOrder
	FilePath string
	Value    string
	KeyPath  string
}

ChangeResult represents the result of applying a change.

func (ChangeResult) String

func (cr ChangeResult) String() string

String returns a string representation of the change result.

type EvalContext

type EvalContext struct {
	// CurrentFile is the path to the file being processed
	CurrentFile string

	// CurrentDocument is the YAML document being processed (can be nil)
	CurrentDocument *yaml.Node

	// Variables is a scratchpad of variables in scope for argument resolution
	Variables map[string]string

	// Functions is the list of available functions
	Functions []config.FunctionDefinition

	// CloudHome is the base directory for resolving relative paths
	CloudHome string

	// ScriptsDir is the directory containing scripts
	ScriptsDir string

	// FilesDir is the directory containing files
	FilesDir string
}

EvalContext provides the context for evaluating ValueFrom expressions. It contains the current file and document being processed, as well as a scratchpad of variables available for argument resolution.

func NewEvalContext

func NewEvalContext(cloudHome, scriptsDir, filesDir string, functions []config.FunctionDefinition) *EvalContext

NewEvalContext creates a new evaluation context.

func (*EvalContext) Evaluate

func (ctx *EvalContext) Evaluate(valueFrom config.ValueFrom) (string, error)

Evaluate evaluates a ValueFrom expression and returns the resulting value.

func (*EvalContext) GetVariable

func (ctx *EvalContext) GetVariable(name string) (string, bool)

GetVariable retrieves a variable from the current context.

func (*EvalContext) SetVariable

func (ctx *EvalContext) SetVariable(name, value string)

SetVariable sets a variable in the current context.

func (*EvalContext) WithDocument

func (ctx *EvalContext) WithDocument(doc *yaml.Node) *EvalContext

WithDocument returns a new context with the specified document set.

func (*EvalContext) WithFile

func (ctx *EvalContext) WithFile(filePath string) *EvalContext

WithFile returns a new context with the specified file set.

func (*EvalContext) WithVariables

func (ctx *EvalContext) WithVariables(vars map[string]string) *EvalContext

WithVariables returns a new context with additional variables.
