tg 5c2a0a1efc fix C array arithmetics 2017-04-28 04:13:19 +00:00
tg dba2efa290 oops, ctypes are indexed by ASCII value even on EBCDIC systems 2017-04-28 03:51:14 +00:00
tg d905bd16e1 rename asc() to asciibetical() to make clear it’s for POSIX ordering only 
and switch remaining consumers, except the allowed one, to rtt2asc()
 2017-04-28 03:46:50 +00:00
tg 1c6b2d1cb8 allow backslash escapes for bind for ^ and \ o̲n̲l̲y̲; also more EBCDIC-friendly 2017-04-28 03:37:44 +00:00
tg fba6940ba4 control character madness, but more compiler-friendly 2017-04-28 03:28:19 +00:00

tg 1289bc69fb apply most of the remaining parts of the EBCDIC patch, sans the CTRL() changes 2017-04-28 02:24:58 +00:00
tg d658ad626b commit the EBCDIC run-time table conversion code, so it can be reviewed 
XXX there’s still the issue of compile-time character conversion, and
XXX that runtime m̲u̲s̲t̲ use a compatible codepage, which we cannot check,
XXX and that we need the POSIX portable character set mapped, which we
XXX decide to not check (due to the above, mostly)

tg 8df7c0c94a BEL was, and Vi mode is, not EBCDIC-safe 2017-04-28 00:49:33 +00:00

tg 884153131d prepare for EBCDIC target environments (with -E option) 
this differs from EBCDIC build hosts which can be autodetected

tg 5c6936ddc8 debugging 1/2 2017-04-27 18:44:35 +00:00
tg 3dff460cde prepare the new fast character classes, not live yet: need sanity check 
unfortunately we need at least 21 or so, maybe 19, classes, so sizing
things down to short is not possible; we can splurge with 32 bit thus
 2017-04-22 00:07:10 +00:00
tg d3be19ac69 now actually do comparisons for sorting ASCIIbetically 2017-04-21 20:06:06 +00:00
tg e18a509a80 make ord() result unsigned int; add asc() which is: 
• not designed to be emitted, only used in comparisons with
  other asc() results
• on EBCDIC platforms, the mapping of an EBCDIC octet to their
  corresponding ASCII or Unicode/UCS-4 codepoint or, if there
  is no mapping, a distinct value above all valid Unicode codepoints
• on nōn-EBCDIC platforms, just the identity mapping of the input
  octet into their ord() value

Intended use are ASCII-ish character ops, including ranges (“A-Z”),
mapping from those to the corresponding digit offset, and sorting
of things in an ASCIIbetical way
