| Overview |  |
| do/2 | execute the selected providers. |
| format_error/1 | convert a given exception's payload into an io description. |
| init_command/2 | initial command set up; based on the first fragment of the command, dispatch to special environments. |
| process_command/2 | Dispatches a given command based on the current state. |
| process_namespace/2 | parse the commands starting at the namespace level; a namespace is found if the first keyword to match is not belonging to an existing provider, and iff the keyword also matches a registered namespace. |
do(Rest::[{atom(), atom()}], State::rebar_state:t()) -> {ok, rebar_state:t()} | {error, string()} | {error, {module(), any()}}
execute the selected providers. If a chain of providers has been returned, run them one after the other, while piping the state from the first into the next one.
format_error(X1::any()) -> iolist()
convert a given exception's payload into an io description.
init_command(State::rebar_state:t(), Command::atom()) -> {ok, rebar_state:t()} | {error, term()}
initial command set up; based on the first fragment of the
command, dispatch to special environments. The keywords for
do and as are implicitly reserved here, barring them from
being used as other commands or namespaces.
process_command(State::rebar_state:t(), Command::atom()) -> {ok, rebar_state:t()} | {error, string()} | {error, {module(), any()}}
Dispatches a given command based on the current state.
This requires mapping a command name to a specific provider.
as and do are still treated as special providers here.
Basic profile application may also be run.
process_namespace(State::rebar_state:t(), Command::atom()) -> {error, term()} | {ok, rebar_state:t(), atom()}
parse the commands starting at the namespace level;
a namespace is found if the first keyword to match is not
belonging to an existing provider, and iff the keyword also
matches a registered namespace.
The command to run is returned last; for namespaces, some
magic is done implicitly calling do as an indirect dispatcher.
