- aug-init #!key root loadpath (flags '())procedure
Initializes the Augeas library and returns an opaque augeus record object which you pass to the other API calls.
On failure, raises an error. Unlike the other API calls, this is currently a generic exception, not an (exn augeas ...).
- A string representing the filesystem root. If omitted or #f, uses the environment variable AUGEAS_ROOT, or failing that, "/".
- A colon-separated list of directories to search for modules. May be omitted or #f. This is in addition to the standard load path and the env var AUGEAS_LENS_LIB.
- A list of flags (see below).
Flags is a list containing at most one of the save- flags:
save-overwrite Overwrite the original file (the default behavior) save-backup Copy the original file to file.augsave, then overwrite the original file save-newfile Save changes into file.augnew; do not overwrite original file save-noop Make save a no-op process, just record what would have changed into /augeas/events/saved
and any of these flags:
type-check Typecheck lenses; very expensive no-stdinc Do not search the builtin default directories for modules no-load Do not load the tree of files no-module-autoload Do not autoload modules from the search path enable-span Load span positions for nodes; required if using aug-span
