Research direction

The issue points to processor.customMarkers and the templates used by the examples; start by tracing how custom markers are matched when a marker has an equals sign. Confirm that an env marker value such as MAX_OPEN_CONNS is available to the templates and produces the requested extra column.

Written by the indexing model from the issue text.

Description

Allow custom markers to have a value like kubebuilder markers.

type Config struct {
   // +kubebuilder:default=25
   MaxOpenConns int `json:"maxOpenConns,omitempty"`
}

Motivation is to define an env custom marker to generate an extra column with the equivalent environment variable name.

type Config struct {
   // +env="MAX_OPEN_CONNS"
   MaxOpenConns int `json:"maxOpenConns,omitempty"`
}

I tried implementing this using the existing processor.customMarkers config and modified templates like the examples, but it seems like the markers are not matched if they are followed by an equals sign.
