stat name
stat runs os.Stat on name. If name
exists it returns structured data. If name does not exist then it returns a
false value. If os.Stat returns any other error then it raises an error. The
structured value returned if name exists contains the fields name, size,
mode, perm, modTime, isDir, and type.
stat is not hermetic: its return value depends on the state of the filesystem
at the moment the template is executed. Exercise caution when using it in your
templates.
Example
{{ if stat (joinPath .chezmoi.homeDir ".pyenv") }}
# ~/.pyenv exists
{{ end }}
