Field path improvements (hl7-field.sh + every tool that uses it):
- Accept both `.` and `-` as separators:
PID.3 == PID-3
PV1.3.4 == PV1-3.4 == PV1-3-4 == PV1.3-4
- Field-name aliases (case-insensitive):
mrn → PID.3
account / account_number → PID.18
name / patient_name → PID.5
dob / birthdate → PID.7
ssn → PID.19
visit / encounter / csn → PV1.19
attending → PV1.7
event → MSH.9.2
control_id / msgid → MSH.10
...and ~40 more covering MSH/PID/PV1/EVN/NK1/GT1/IN1/OBR/OBX/DG1/ORC
- Aliases also accept component/subcomponent suffixes:
name.2 → PID.5.2
mrn.1 → PID.3.1
Filter operators (nc-msgs.sh --field):
PATH=VALUE exact equality
PATH!=VALUE not equal
PATH~VALUE contains (case-insensitive)
PATH!~VALUE does not contain (case-insensitive)
PATH=NULL /= null / empty / absent
PATH!=NULL present (any non-empty rep)
PATH=* wildcard — any non-empty value
Multiple --field flags AND; for OR, run two queries.
New output formats for nc-msgs.sh:
text (default) segments per line + metadata header per message
oneline one message per line, segments joined with a ⏎ marker
fields each non-empty field on its own line: "SEG.N: value"
mp alias for fields (matches v1 `mp` semantic)
labeled fields with friendly aliases: "MSH.9 (msg_type): ADT^A08"
raw, json, count — unchanged
MANUAL.md updated with the full operator + format reference.
