Now that routes can include optional attributes, print the expected
syntax in case of parsing failure.
$ nmcli connection modify dummy ipv4.routes a
Error: failed to modify ipv4.routes: invalid route: Invalid IPv4
address 'a'. The valid syntax is: 'ip[/prefix] [next-hop] [metric]
[attribute=val]... [,ip[/prefix] ...]'.
Before refactoring nmcli recently, field names were marked for translation.
Note that for the property names, marking them had no effect as only
plain strings can be marked with N_().
Note how --fields are also an input argument. The input should be
independent of the locale and not translated. Likewise, when printing
the header names, they should not be translated to match the --fields
option.
$ LANG=de_DE.utf8 nmcli --fields GENERAL.DEVICE device show enp0s25
GENERAL.GERÄT: enp0s25
Drop the translation marks.
Ensure we call G_IS_ENUM_CLASS() or G_IS_FLAGS_CLASS() only on classed
types.

That allows for the property list to contain derived
property types. Also, the list can be directly passed
off as a "const NMMetaAbstractInfo *const*" list.
This change (improves) behavior.
Before, we would only complete
if (g_strcmp0 (con_type, nmc_tab_completion.con_type) != 0)
which doesn't really make sense as it depends on the slave-type,
not nmc_tab_completion.con_type.
This changes behavior, in that yes|no prompt and answer is no longer
localized.
For command line arguments, I think it is always wrong for nmcli to
behave differently based on the localization. That is, input properties
on command line should not be translated.
One could make an argument, that in interactive mode that is different
and the user can be prompted in the his language.
But I think for consistency, it is wrong to ask for localized nmcli input.
- have the "self" argument first, before the environment arguments.
It's more idiomatic.
- from within cli, always pass nmc_meta_environment and nmc_meta_arg
where needed.
- drop the union in NMMetaAbstractInfo. I was suppost to make casts
nicer, but it doesn't really.
Depending on the get_type argument, we don't only want
to return strings, but arbitrary pointers.
The out_to_free argument still makes sense, but depending on
the get-type you must know how to free the pointer.
Currently we only have two get-types: PRETTY and PARSABLE.
In the future we may want to add more of those, so the
default behavior when encountering an unrecognized get-type
should be PARSABLE.
Don't ever check whether get-type is PARSABLE. Check instead,
whether it is PRETTY (the non-default) or do the default (PARSABLE).
When generating output data, nmcli iterates over a list of
property-descriptors (nmc_fields_ip4_config), creates an intermediate
array (output_data) and finally prints it.
However, previously both the meta data (nmc_fields_ip4_config) and
the intermediate format use the same type NmcOutputField. This means,
certain fields are relevant to describe a property, and other fields
are output/formatting fields.
Split this up. Now, the meta data is tracked in form of an NMMetaAbstractInfo
lists. This separates the information about properties from intermediate steps
during creation of the output.
Note that currently functions like print_ip4_config() still have all the
knowledge about how to generate the output. That is wrong, instead, the
meta data (NMMetaAbstractInfo) should describe how to create the output
and then all those functions could be replaced. This means, later we want
to add more knowledge to the NMMetaAbstractInfo, so it is important to
keep them separate from NmcOutputField.
Embed a @meta_type structure in NMMetaSettingInfoEditor and
NMMetaPropertyInfo. This allows to make the NMMeta*Info instances
themself to become generic and they can be passed around as generic
NMMetaAbstractInfo types.
For one, the embedded NMMetaType pointer can be used to determine
of which type a NMMetaAbstractInfo instance is. On the other hand,
the NMMetaType struct can be extended to be a VTable to provide
generic access to the type.
In the end, both NMMetaSettingInfoEditor and NMMetaPropertyInfo are
conceptionally very similar: the describe a certain type and provide
accessors.
In nmcli we have yet another NMMetaAbstractInfo type: NmcOutputField
will be modified to become another implementation of meta data (it
already is, it just cannot be used interchangable with the other
types).
Also, embed the NMMetaSettingInfoEditor in the NMMetaPropertyInfo
instance. This allows from a given NMMetaPropertyInfo to retrieve it's
parent NMMetaSettingInfoEditor.
This check requires additional information about the environment, that
is about the present connections in NMClient.
"nm-meta-setting-desc.c" should be independent from the libnm D-Bus
cache, hence move this code to "settings.c".
The lower layers are concerned with handling settings. They should not
be aware of how to notify about warnings. Instead, signal them via
the warn_fcn() hook.
For G_TYPE_BOOLEAN, let it get handled by the getter hook instead
of modifying system-wide behavior of glib.
Also, there are no properties of G_TYPE_CHAR. Just drop that.
