bibconvert formatting functions:
================================
ADD(prefix,suffix) - add prefix/suffix
KB(kb_file,mode) - lookup in kb_file and replace value
ABR(N,suffix) - abbreviate to N places with suffix
ABRX() - abbreviate exclusively words longer
ABRW() - abbreviate word (limit from right)
REP(x,y) - replace
SUP(type) - remove characters of certain TYPE
LIM(n,side) - limit to n letters from L/R
LIMW(string,side) - L/R after split on string
WORDS(n,side) - limit to n words from L/R
IF(value,valueT,valueF) - replace on IF condition
MINL(n) - replace words shorter than n
MINLW(n) - replace words shorter than n
MAXL(n) - replace words longer than n
EXPW(type) - replace word from value containing TYPE
EXP(STR,0/1) - replace word from value containing string
NUM() - take only digits in given string
SHAPE() - remove extra space
UP() - to uppercase
DOWN() - to lowercase
CAP() - make capitals each word
SPLIT(n,h,str,from) - only for final Aleph field, i.e. AB , maintain whole words
SPLITW(sep,h,str,from) - only for final Aleph field, split on string
CONF(filed,value,0/1) - confirm validity of output line (check other field)
CONFL(substr,0/1) - confirm validity of output line (check field being processed)
CUT(prefix,postfix) - remove substring from side
RANGE(MIN,MAX) - select items in repetitive fields
RE(regexp) - regular expressions
IFDEFP(field,value,0/1) - confirm validity of output line (check other field)
NOTE: This function works for CONSTANT
lines - those without any variable values in
them.
JOINMULTILINES(prefix,suffix) - Given a field-value with newlines in it,
split the field on the new lines (\n), separating
them with prefix, then suffix. E.g.:
For the field XX with the value:
Test
Case, A
And the function call:
<:XX^::XX::JOINMULTILINES(<subfield code="a">,</subfield>):>
The results would be:
<subfield code="a">Test</subfield><subfield code="a">Case, A</subfield>
One note on this: <:XX^::XX:
Without the ^ the newlines will be lost as
bibconvert will remove them, so you'll
never see an effect from this function.
bibconvert character TYPES
==========================

NUM - numeric
NNUM - not numeric
