Please refer to for details. Cobra 1.1 standardized its zsh completion support to align it with its other shell completions. Although the API was kept backwards-compatible, some small changes in behavior were introduced. See further below for more details on these deprecations. `cmd.MarkZshCompPositionalArgumentFile(pos, []string{})` is no longer needed. It is therefore deprecated* and silently ignored. `cmd.MarkZshCompPositionalArgumentFile(pos, glob[])` is deprecated* and silently ignored. Instead use `ValidArgsFunction` with `ShellCompDirectiveFilterFileExt`. `cmd.MarkZshCompPositionalArgumentWords()` is deprecated* and silently ignored. Instead use `ValidArgsFunction`. Noun completion |Old behavior|New behavior| ||| |No file completion by default (opposite of bash)|File completion by default; use `ValidArgsFunction` with `ShellCompDirectiveNoFileComp` to turn off file completion on a per-argument basis| |Completion of flag names without the `-` prefix having been typed|Flag names are only completed if the user has typed the first `-`| `cmd.MarkZshCompPositionalArgumentFile(pos, []string{})` used to turn on file completion on a per-argument position basis|File completion for all arguments by default; `cmd.MarkZshCompPositionalArgumentFile()` is deprecated and silently ignored| |`cmd.MarkZshCompPositionalArgumentFile(pos, glob[])` used to turn on file completion with glob filtering on a per-argument position basis (zsh-specific)|`cmd.MarkZshCompPositionalArgumentFile()` is deprecated and silently ignored; use `ValidArgsFunction` with `ShellCompDirectiveFilterFileExt` for file extension filtering (not full glob filtering)| |`cmd.MarkZshCompPositionalArgumentWords(pos, words[])` used to provide completion choices on a per-argument position basis (zsh-specific)|`cmd.MarkZshCompPositionalArgumentWords()` is deprecated and silently ignored; use `ValidArgsFunction` to achieve the same behavior| Flag-value completion |Old behavior|New behavior| ||| |No file completion by default (opposite of bash)|File completion by default; use `RegisterFlagCompletionFunc()` with `ShellCompDirectiveNoFileComp` to turn off file completion| |`cmd.MarkFlagFilename(flag, []string{})` and similar used to turn on file completion|File completion by default; `cmd.MarkFlagFilename(flag, []string{})` no longer needed in this context and silently ignored| |`cmd.MarkFlagFilename(flag, glob[])` used to turn on file completion with glob filtering (syntax of `[]string{".yaml", ".yml"}` incompatible with bash)|Will continue to work, however, support for bash syntax is added and should be used instead so as to work for all shells (`[]string{"yaml", "yml"}`)| |`cmd.MarkFlagDirname(flag)` only completes directories (zsh-specific)|Has been added for all shells| |Completion of a flag name does not repeat, unless flag is of type `Array` or `Slice` (not supported by bash)|Retained for `zsh` and added to `fish`| |Completion of a flag name does not provide the `=` form (unlike bash)|Retained for `zsh` and added to `fish`| Improvements Custom completion support (`ValidArgsFunction` and `RegisterFlagCompletionFunc()`) File completion by default if no other completions found Handling of required flags File extension filtering no longer mutually exclusive with bash usage Completion of directory names within* another directory Support for `=` form of flags
