Cobra, the CLI commander in use in Hugo, has some long awaited improvements in the error handling department. This enables a more centralized error handling approach. This commit introduces that by changing all the command funcs to `RunE`: * The core part of the error logging, usage logging and `os.Exit(-1)` is now performed in one place and that one place only. * The usage text is now only shown on invalid arguments etc. (user errors) Fixes #1502

Use: "autocomplete",
|

Short: "Generate shell autocompletion script for Hugo",
|

Long: `Generates a shell autocompletion script for Hugo.
|
|
|
|
NOTE: The current version supports Bash only.
|
|
This should work for *nix systems with Bash installed.
|
|
|
|
By default, the file is written directly to /etc/bash_completion.d
|
|
for convenience, and the command may need superuser rights, e.g.:
|
|
|
|
$ sudo hugo genautocomplete
|
|
|
|
Add ` + "`--completionfile=/path/to/file`" + ` flag to set alternative
|
|
file-path and name.
|
|
|
|
Logout and in again to reload the completion scripts,
|
|
or just source them in directly:
|
|
|
|
$ . /etc/bash_completion`,
|
|
|
|
RunE: func(cmd *cobra.Command, args []string) error {
|
|
if autocompleteType != "bash" {
|
|
return newUserError("Only Bash is supported for now")
|
|
}
|
|
|
|
