# "Auto" script redirection.
|
|
#
|
|
# As a matter of convenience users can have a set of saved commandline options
|
|
# which will be automatically included in every execution of live-build. How
|
|
# this works is that the save file is itself a shell script saved in the config
|
|
# directory (one per top-level live-build command in fact). When `lb config`,
|
|
# `lb build` or `lb clean` is run, these scripts, if they see that an "auto"
|
|
# file exists in the config, they run that file, passing along any user
|
|
# arguments, and terminate once that ends. The "auto" script simply re-executes
|
|
# the same command (e.g. `lb config`), only with a first param of "noauto",
|
|
# used to stop an infinite loop of further redirection, then a fixed saved set
|
|
# of command line options, as saved in the file by the user, then any
|
|
# additional command line arguments passed into the script. This is simply a
|
|
# means of injecting a saved set of command line options into the execution of
|
|
# live-build.
|
|
#
|
|
# As for this function, it is a simple helper, used by the top-level commands
|
|
# to perform the redirection if the relevant "auto" file exists. It should only
|
|
# be called if the calling command script was not run with "noauto" as the
|
|
# first argument (the purpose of which was just described).
