[scarf005]

Summary

SUMMARY: Features "allow installing non-sterile CBM when Infection Immune"

Purpose of change

inspired by Cataclysm-TISH-team/Cataclysm-TISH#60

Describe the solution

Infection Immune(INFRESIST) trait will ignore checking for CBM sterileness.

Testing

Before Infection Immune	After Infection Immune

I forgot to make it in my PR, but I recommend to update the bionic's description and mention that it will allow user to make intrusive surgery operations with non-sterile tools. Or maybe maximum directly: you can install non-sterile bionics.

thanks for the suggestion. as CBM implements Non-Sterile using faults as in #1665, they will be displayed via this loop:

Cataclysm-BN/src/item.cpp

Lines 3818 to 3824 in 5343c28

	if( parts->test( iteminfo_parts::DESCRIPTION_FAULTS ) ) {
	for( const fault_id &e : faults ) {
	//~ %1$s is the name of a fault and %2$s is the description of the fault
	info.emplace_back( "DESCRIPTION", string_format( _( "* <bad>%1$s</bad>. %2$s" ),
	e.obj().name(), e.obj().description() ) );
	}
	}

i think there's some possibilities to handling this situation:

• jsonize fault negation. the problem with this approach is that infection immunity is likely the only trait that lets you skip mending. it'd be a code bloat to support only one instances of fault.

{
    "id": "fault_bionic_nonsterile",
    "type": "fault",
    "name": { "str": "Non-sterile" },
    "description": "This bionic needs to be sterilized before it can be installed.",
    "nagated_by": [ "INFRESIST" ] // <- case 1
	"nagated_by": [ { "type": "trait", "value": "INFRESIST" } ] // <- also check for types?
  }

• add check for infection immune inside the loop. feels very hacky.

Nice idea.
In the future, the primary risk of zombie "filth" will probably be changed to semi-permanent (tied to the installed bionic) mutagenic, but that's distant future.

Almost everything works correctly: autodoc installs all function as expected (tested various combos of with and without Deadened and Infection Immune to ensure anesthesia interactions all still work) but attempting to activate a non-sterile CBM with Manaul Bionic Installation is still blocked even with Infection Immune.

It looks to be a dead-easy two line change in another file so instead of holding this up I'll implement the Manual Bionic Installation version of this in a follow-up PR.
