📝 Walkthrough

Walkthrough

The CLI replaces legacy Bash completion callbacks with posener/complete predictors, adds shell completion installation APIs and tests, changes flag error handling, and removes the altsrc package and its generated alternate-input-source support.

Changes

Shell completion migration

Layer / File(s) Summary
Flag and command completion contracts
command.go, flag.go, flag_generated.go, generate-flag-types.py
Flags now return errors and expose completion predictors. Commands use CustomCompletePredictor. Generated flag types include predictor fields where applicable.
Completion request execution
app.go, context.go, complete.go, help.go
App.Run handles COMP_LINE requests before normal parsing. Completion trees include visible commands, aliases, global flags, and predictors. Legacy completion dispatch is removed.
Completion validation
app_test.go, complete_test.go, help_test.go
Tests cover command, alias, hidden-command, subcommand, argument, flag, flag-value, and disabled-completion behavior.
Shell completion installation
install.go, install_test.go
The package detects supported shells and provides installation, removal, status, and setup operations with error handling tests.
Module and documentation updates
go.mod, cli.go
The module uses the /v2 path and updated completion dependencies. Package examples and the generation directive use current formatting.
Alternate input-source removal
altsrc/*
The altsrc implementation, generated wrappers, loaders, interfaces, helpers, and related tests are deleted.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 37379

The PR adds shell-completion installation detection, but command names containing shell markers can cause incorrect setup reporting, while root-level flags remain unavailable during completion. The change is mergeable with explicit owner follow-up on these bounded correctness and usability issues.

Poem

A rabbit checks the flags at dawn
Predictors hop where callbacks’re gone
Bash, zsh, and fish join the tune
Hidden commands hide from the moon
The old source leaves a tidy burrow

Inline comments:
In `@command.go`:
- Around line 31-33: Preserve backward compatibility for the public API changes
in command.go (Command.BashComplete) and flag.go (Flag.Apply and
Flag.GetPredictor), or release them under a new major module path; do not leave
downstream github.com/minio/cli consumers with compile-breaking contract
changes.

In `@complete_test.go`:
- Around line 14-22: Remove the unused testFlagPredictor type and its Predictor
method from the test code, leaving all other test helpers and behavior
unchanged.

In `@complete.go`:
- Around line 45-47: Update both alias-registration loops for top-level and
nested commands to skip adding aliases when the command’s HiddenAliases field is
true, while preserving current completion behavior otherwise. Add coverage
verifying hidden aliases are omitted for both top-level and nested commands.
- Around line 35-52: The cmdToCompleteCmd conversion must propagate
App.GlobalFlags predictors into each generated child complete.Command, except
for commands with NoGlobalFlags set. Update the recursive child conversion and
add a regression test covering completion such as “child --profile ” returning
predictor values rather than flag names.

In `@install.go`:
- Around line 102-105: Update SetupShellCompletion to check whether completion
is installed specifically for res.Shell rather than using the broad
IsShellCompletionInstalled result across all shells; add a regression test
covering another shell being configured while res.Shell still requires
installation.

67-70: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Expose App.Flags at the root completion command.

App.Run parses root arguments from a.Flags, but shellCompleteCommand sets only GlobalFlags on the root complete.Command. Because complete.Command.Flags supplies completions for the current command, root-local flag names and predictors are omitted. Set Flags: flagsToCompleteFlags(a.Flags) and add coverage for a root-local flag and predictor.

@coderabbitai that is a surprisingly difficult thing to do and was not done previously in the place this is modeled after so no behavior regression. It will be its own PR
