It yields the following behavior: +``` +bash-5.1$ helm repo add [tab] +You must choose a name for the repo you are adding + +bash-5.1$ helm repo add grafana [tab] +You must specify the URL for the repo you are adding + +bash-5.1$ helm repo add grafana https://grafana.github.io/helm-charts [tab] +This command does not take any more arguments +``` +**Hint**: As can be seen in the above example, a good place to use Active Help messages is when the normal completion system does not provide any suggestions. In such cases, Active Help nicely supplements the normal shell completions. + +### Active Help for flags + +Providing Active Help for flags is done in the same fashion as for nouns, but using the completion function registered for the flag.

It is entirely up to the program to define the type of configurability of Active Help that it wants to offer, if any. +Allowing to configure Active Help is entirely optional; you can use Active Help in your program without doing anything about Active Help configuration. + +The way to configure Active Help is to use the program's Active Help environment +variable. That variable is named `_ACTIVE_HELP` where `` is the name of your +program in uppercase with any `-` replaced by an `_`. The variable should be set by the user to whatever +Active Help configuration values are supported by the program. + +For example, say `helm` has chosen to support three levels for Active Help: `on`, `off`, `local`. Then a user +would set the desired behavior to `local` by doing `export HELM_ACTIVE_HELP=local` in their shell. + +For simplicity, when in `cmd.ValidArgsFunction(...)` or a flag's completion function, the program should read the +Active Help configuration using the `cobra.GetActiveHelpConfig(cmd)` function and select what Active Help messages +should or should not be added (instead of reading the environment variable directly). + +For example: +```go +ValidArgsFunction: func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) { + activeHelpLevel := cobra.GetActiveHelpConfig(cmd) + + var comps []string + if len(args) == 0 { + if activeHelpLevel != "off" { + comps = cobra.AppendActiveHelp(comps, "You must choose a name for the repo you are adding") + } + } else if len(args) == 1 { + if activeHelpLevel != "off" { + comps = cobra.AppendActiveHelp(comps, "You must specify the URL for the repo you are adding") + } + } else { + if activeHelpLevel == "local" { + comps = cobra.AppendActiveHelp(comps, "This command does not take any more arguments") + } + } + return comps, cobra.ShellCompDirectiveNoFileComp +}, +``` +**Note 1**: If the `_ACTIVE_HELP` environment variable is set to the string "0", Cobra will automatically disable all Active Help output (even if some output was specified by the program using the `cobra.AppendActiveHelp(...)` function). Using "0" can simplify your code in situations where you want to blindly disable Active Help without having to call `cobra.GetActiveHelpConfig(cmd)` explicitly. + +**Note 2**: If a user wants to disable Active Help for every single program based on Cobra, she can set the environment variable `COBRA_ACTIVE_HELP` to "0". In this case `cobra.GetActiveHelpConfig(cmd)` will return "0" no matter what the variable `_ACTIVE_HELP` is set to. + +**Note 3**: If the user does not set `_ACTIVE_HELP` or `COBRA_ACTIVE_HELP` (which will be a common case), the default value for the Active Help configuration returned by `cobra.GetActiveHelpConfig(cmd)` will be the empty string. +## Active Help with Cobra's default completion command + +Cobra provides a default `completion` command for programs that wish to use it. +When using the default `completion` command, Active Help is configurable in the same +fashion as described above using environment variables. You may wish to document this in more +details for your users. + +## Debugging Active Help + +Debugging your Active Help code is done in the same way as debugging your dynamic completion code, which is with Cobra's hidden `__complete` command. Please refer to [debugging shell completion](shell_completions.md#debugging) for details. + +When debugging with the `__complete` command, if you want to specify different Active Help configurations, you should use the active help environment variable. That variable is named `_ACTIVE_HELP` where any `-` is replaced by an `_`. For example, we can test deactivating some Active Help as shown below: +``` +$ HELM_ACTIVE_HELP=1 bin/helm __complete install wordpress bitnami/h +bitnami/haproxy +bitnami/harbor +_activeHelp_
