We already have
- data sources (nm_cli, connections or settings)
- meta data information how to access the data sources (NMMetaAbstractInfo,
NmcMetaGenericInfo, NMMetaPropertyInfo)
Add now a generic way to output cli data using nmc_print(). It gets a
list of data-sources (@targets) and a list of available fields (meta
data). It also gets cli configuration (NmcConfig) and field selector
strings (@field_str).
Based on that, it should output the desired data.
This is intended to replaces the previous approach, where functions like
show_nm_status() have full knowledge about how to access the data and
create an intermediate output format (NmcOutputData, NmcOutputField)
that was printed via print_data().
show_nm_status() contained both knowledge about the data itself (how to
print a value) and intimate knoweledge about the output intermediate
format. Also, the intermediate format is hard to understand. For
example, sometimes we put the field prefix in NmcOutputField at index 0
and via the NmcOfFlags we control how to output the data.
Clearly separate the responsibilities.
- The meta data (NmcMetaGenericInfo) is only concerned with converting
a data source to a string (or a color format).
- the field selection (@field_str) only cares about parsing the list
of NMMetaAbstractInfo.
- _print_fill() populates a table with output values and header
entries.
- _print_do() prints the previously prepared table.
The advantage is that if you want to change anything, you only need to
touch a particular part.
This is only a show-case for `nmcli general status`. Parts are still
un-implemented and will follow.
This changes behavior for --terse mode: the values are now no longer
translated:
$ LANG=de_DE.utf8 nmcli -t --mode multiline general
