grpcurl-autocomplete

Tab-completion for grpcurl services and methods, using the target server's own gRPC reflection (via grpcurl ... list).

Supports PowerShell variables and $env: values used in the command line, and narrows package-qualified service/method names one dot-segment at a time:

$myserver = 'localhost:50051'
grpcurl -plaintext $myserver <Tab>                     # narrows one package segment at a time: 'co' -> 'contoso.'
grpcurl -plaintext $myserver contoso.myservice<Tab>     # once a full service name matches, lists its methods
grpcurl -plaintext $myserver contoso.myservice.Say<Tab> # narrows methods in dot form (service.Method), same as
grpcurl -plaintext $myserver contoso.myservice/Say<Tab> # ... slash form (service/Method) -- grpcurl accepts both
grpcurl -H "Authorization: $env:myToken" -plaintext $myserver <Tab>

Both a PowerShell and a bash version are included, with feature parity between them.

PowerShell setup

Requires PowerShell 7+ and grpcurl on PATH.

Add to your $PROFILE:

Import-Module "/path/to/grpcurl-autocomplete/grpcurl-autocomplete.psd1"

PowerShell tests

pwsh ./tests/Test-GrpcurlCompletion.ps1

Bash setup

Requires bash 4+ (associative arrays) and grpcurl on PATH.

Add to your .bashrc:

source "/path/to/grpcurl-autocomplete/grpcurl-autocomplete.bash"

Bash has one variable namespace, so $VAR in the command line covers both plain variables and exported environment variables -- there's no separate $env:VAR form to write, unlike PowerShell.

Bash tests

bash tests/test-grpcurl-completion.bash
