+; this file contains a script of tests to run through regress.exe
+;
+; comments start with a semicolon and proceed to the end of the line
+;
+; changes to regular expression compile flags start with a "-" as the first
+; non-whitespace character and consist of a list of the printable names
+; of the flags, for example "match_default"
+;
+; Other lines contain a test to perform using the current flag status
+; the first token contains the expression to compile, the second the string
+; to match it against. If the second string is "!" then the expression should
+; not compile, that is the first string is an invalid regular expression.
+; This is then followed by a list of integers that specify what should match,
+; each pair represents the starting and ending positions of a subexpression
+; starting with the zeroth subexpression (the whole match).
+; A value of -1 indicates that the subexpression should not take part in the
+; match at all, if the first value is -1 then no part of the expression should
+; match the string.

+# regular expression test set
+# Lines are at least three fields, separated by one or more tabs.  "" stands
+# for an empty field.  First field is an RE.  Second field is flags.  If
+# C flag given, regcomp() is expected to fail, and the third field is the
+# error name (minus the leading REG_).
+#
+# Otherwise it is expected to succeed, and the third field is the string to
+# try matching it against.  If there is no fourth field, the match is
+# expected to fail.  If there is a fourth field, it is the substring that
+# the RE is expected to match.  If there is a fifth field, it is a comma-
+# separated list of what the subexpressions should match, with - indicating
+# no match for that one.  In both the fourth and fifth fields, a (sub)field
+# starting with @ indicates that the (sub)expression is expected to match
+# a null string followed by the stuff after the @; this provides a way to
+# test where null strings match.  The character `N' in REs and strings
+# is newline, `S' is space, `T' is tab, `Z' is NUL.

+#!/bin/sed -nf
+#  dc.sed - an arbitrary precision RPN calculator
+#  Created by Greg Ubben <gsu@romulus.ncsc.mil> early 1995, late 1996
+#
+#  Dedicated to MAC's memory of the IBM 1620 ("CADET") computer.
+#  @(#)GSU dc.sed 1.1 06-Mar-1999 [non-explanatory]
+#
+#  Examples:
+#	sqrt(2) to 10 digits:	echo "10k 2vp" | dc.sed
+#	20 factorial:		echo "[d1-d1<!*]s! 20l!xp" | dc.sed
+#	sin(ln(7)):		echo "s(l(7))" | bc -c /usr/lib/lib.b | dc.sed
+#	hex to base 60:		echo "60o16i 6B407.CAFE p" | dc.sed
+#	tests most of dc.sed:	echo 16oAk2vp | dc.sed
+#
+#  To debug or analyze, give the dc Y command as input or add it to
+#  embedded dc routines, or add the sed p command to the beginning of
+#  the main loop or at various points in the low-level sed routines.
+#  If you need to allow [|~] characters in the input, filter this
+#  script through "tr '|~' '\36\37'" first (or use dc.pl).
+#
+#  Not implemented:	! \
+#  But implemented:	K Y t # !< !> != fractional-bases
+#  SunOS limits:	199/199 commands (though could pack in 10-20 more)
+#  Limitations:		scale <= 999; |obase| >= 1; input digits in [0..F]
+#  Completed:		1am Feb 4, 1997

+A dialogue on poverty
+2
+
+3
+        On the night when the rain beats,
+4
+        Driven by the wind,
+5
+        On the night when the snowflakes mingle
+6
+        With a sleety rain,
+7
+        I feel so helplessly cold.
+8
+        I nibble at a lump of salt,
+9
+        Sip the hot, oft-diluted dregs of _sake_;
+10
+        And coughing, snuffling,
+11
+        And stroking my scanty beard,
+12
+        I say in my pride,
+13
+        "There's none worthy, save I!"
+14
+        But I shiver still with cold.
+15
+        I pull up my hempen bedclothes,
+16
+        Wear what few sleeveless clothes I have,
+17
+        But cold and bitter is the night!
+18
+        As for those poorer than myself,        
+19
+        Their parents must be cold and hungry,
+20
+        Their wives and children beg and cry.
+21
+        Then, how do you struggle through life?
+22
+        
+23
+        Wide as they call the heaven and earth,
+24
+        For me they have shrunk quite small;
+25
+        Bright though they call the sun and moon,
+26
+        They never shine for me.
+27
+        Is it the same with all men,
+28
+        Or for me alone?
+29
+        By rare chance I was born a man
+30
+        And no meaner than my fellows,
+31
+        But, wearing unwadded sleeveless clothes
+32
+        In tatters, like weeds waving in the sea,
+33
+        Hanging from my shoulders,
+34
+        And under the sunken roof,
+35
+        Within the leaning walls,
+36
+        Here I lie on straw
+37
+        Spread on bare earth,
+38
+        With my parents at my pillow,
+39
+        And my wife and children at my feet,
+40
+        All huddled in grief and tears.
+41
+        No fire sends up smoke
+42
+        At the cooking-place,
+43
+        And in the cauldron
+44
+        A spider spins its web.
+45
+        With not a grain to cook,
+46
+        We moan like the night thrush.
+47
+        Then, "to cut," as the saying is,
+48
+        "The ends of what is already too short,"
+49
+        The village headman comes,
+50
+        With rod in hand, to our sleeping place,
+51
+        Growling for his dues.
+52
+        Must it be so hopeless --
+53
+        The way of this world?

+The girl on the summit of the load sat motionless, surrounded by tables and chairs with their legs upwards, backed by an oak settle, and ornamented in front by pots of geraniums, myrtles, and cactuses, together with a caged canary -- all probably from the windows of the house just vacated.  There was also a cat in a willow basket, from the partly-opened lid of which she gazed with half-closed eyes, and affectionately-surveyed the small birds around.  The handsome girl waited for some time idly in her place, and the only sound heard in the stillness was the hopping of the canary up and down the perches of its prison.  Then she looked attentively downwards.  It was not at the bird, nor at the cat; it was at an oblong package tied in paper, and lying between them.  She turned her head to learn if the waggoner were coming.  He was not yet in sight; and her eyes crept back to the package, her thoughts seeming to run upon what was inside it.  At length she drew the article into her lap, and untied the paper covering; a small swing looking- glass was disclosed, in which she proceeded to survey herself attentively.  She parted her lips and smiled.  It was a fine morning, and the sun lighted up to a scarlet glow the crimson jacket she wore, and painted a soft lustre upon her bright face and dark hair.  The myrtles, geraniums, and cactuses packed around her were fresh and green, and at such a leafless season they invested the whole concern of horses, waggon, furniture, and girl with a peculiar vernal charm.  What possessed her to indulge in such a performance in the sight of the sparrows, blackbirds, and unperceived farmer who were alone its spectators, -- whether the smile began as a factitious one, to test her capacity in that art, -- nobody knows; it ended certainly in a real smile.  She blushed at herself, and seeing her reflection blush, blushed the more.  The change from the customary spot and necessary occasion of such an act -- from the dressing hour in a bedroom to a time of travelling out of doors -- lent to the idle deed a novelty it did not intrinsically possess.  The picture was a delicate one.  Woman's prescriptive infirmity had stalked into the sunlight, which had clothed it in the freshness of an originality.  A cynical inference was irresistible by Gabriel Oak as he regarded the scene, generous though he fain would have been.  There was no necessity whatever for her looking in the glass.  She did not adjust her hat, or pat her hair, or press a dimple into shape, or do one thing to signify that any such intention had been her motive in taking up the glass.  She simply observed herself as a fair product of Nature in the feminine kind, her thoughts seeming to glide into far-off though likely dramas in which men would play a part -- vistas of probable triumphs -- the smiles being of a phase suggesting that hearts were imagined as lost and won.  Still, this was but conjecture, and the whole series of actions was so idly put forth as to make it rash to assert that intention had any part in them at all.  The waggoner's steps were heard returning.  She put the glass in the paper, and the whole again into its place.  When the waggon had passed on, Gabriel withdrew from his point of espial, and descending into the road, followed the vehicle to the turnpike-gate some way beyond the bottom of the hill, where the object of his contemplation now halted for the payment of toll.  About twenty steps still remained between him and the gate, when he heard a dispute.  It was a difference concerning twopence between the persons with the waggon and the man at the toll-bar.  "Mis'ess's niece is upon the top of the things, and she says that's enough that I've offered ye, you great miser, and she won't pay any more."  These were the waggoner's words.  "Very well; then mis'ess's niece can't pass," said the turnpike-keeper, closing the gate.  Oak looked from one to the other of the disputants, and fell into a reverie.  There was something in the tone of twopence remarkably insignificant.  Threepence had a definite value as money -- it was an appreciable infringement on a day's wages, and, as such, a higgling matter; but twopence -- "Here," he said, stepping forward and handing twopence to the gatekeeper; "let the young woman pass."  He looked up at her then; she heard his words, and looked down.  Gabriel's features adhered throughout their form so exactly to the middle line between the beauty of St. John and the ugliness of Judas Iscariot, as represented in a window of the church he attended, that not a single lineament could be selected and called worthy either of distinction or notoriety.  The red-jacketed and dark-haired maiden seemed to think so too, for she carelessly glanced over him, and told her man to drive on.  She might have looked her thanks to Gabriel on a minute scale, but she did not speak them; more probably she felt none, for in gaining her a passage he had lost her her point, and we know how women take a favour of that kind.  The gatekeeper surveyed the retreating vehicle.  "That's a handsome maid," he said to Oak.  "But she has her faults," said Gabriel.  "True, farmer." "And the greatest of them is -- well, what it is always." "Beating people down? ay, 'tis so." "O no." "What, then?" Gabriel, perhaps a little piqued by the comely traveller's indifference, glanced back to where he had witnessed her performance over the hedge, and said, "Vanity, dude."

The red-jacketed and dark-haired maiden seemed to think so too, for she carelessly glanced over him, and told her man to drive on.  She might have looked her thanks to Gabriel on a minute scale, but she did not speak them; more probably she felt none, for in gaining her a passage he had lost her her point, and we know how women take a favour of that kind.  The gatekeeper surveyed the retreating vehicle.  "That's a handsome maid," he said to Oak.  "But she has her faults," said Gabriel.  "True, farmer." "And the greatest of them is -- well, what it is always." "Beating people down? ay, 'tis so." "O no." "What, then?" Gabriel, perhaps a little piqued by the comely traveller's indifference, glanced back to where he had witnessed her performance over the hedge, and said, "Vanity."/The girl on the summit of the load sat motionless, surrounded by tables and chairs with their legs upwards, backed by an oak settle, and ornamented in front by pots of geraniums, myrtles, and cactuses, together with a caged canary -- all probably from the windows of the house just vacated.  There was also a cat in a willow basket, from the partly-opened lid of which she gazed with half-closed eyes, and affectionately-surveyed the small birds around.  The handsome girl waited for some time idly in her place, and the only sound heard in the stillness was the hopping of the canary up and down the perches of its prison.  Then she looked attentively downwards.  It was not at the bird, nor at the cat; it was at an oblong package tied in paper, and lying between them.  She turned her head to learn if the waggoner were coming.  He was not yet in sight; and her eyes crept back to the package, her thoughts seeming to run upon what was inside it.  At length she drew the article into her lap, and untied the paper covering; a small swing looking- glass was disclosed, in which she proceeded to survey herself attentively.  She parted her lips and smiled.  It was a fine morning, and the sun lighted up to a scarlet glow the crimson jacket she wore, and painted a soft lustre upon her bright face and dark hair.  The myrtles, geraniums, and cactuses packed around her were fresh and green, and at such a leafless season they invested the whole concern of horses, waggon, furniture, and girl with a peculiar vernal charm.  What possessed her to indulge in such a performance in the sight of the sparrows, blackbirds, and unperceived farmer who were alone its spectators, -- whether the smile began as a factitious one, to test her capacity in that art, -- nobody knows; it ended certainly in a real smile.  She blushed at herself, and seeing her reflection blush, blushed the more.  The change from the customary spot and necessary occasion of such an act -- from the dressing hour in a bedroom to a time of travelling out of doors -- lent to the idle deed a novelty it did not intrinsically possess.  The picture was a delicate one.  Woman's prescriptive infirmity had stalked into the sunlight, which had clothed it in the freshness of an originality.  A cynical inference was irresistible by Gabriel Oak as he regarded the scene, generous though he fain would have been.  There was no necessity whatever for her looking in the glass.  She did not adjust her hat, or pat her hair, or press a dimple into shape, or do one thing to signify that any such intention had been her motive in taking up the glass.  She simply observed herself as a fair product of Nature in the feminine kind, her thoughts seeming to glide into far-off though likely dramas in which men would play a part -- vistas of probable triumphs -- the smiles being of a phase suggesting that hearts were imagined as lost and won.  Still, this was but conjecture, and the whole series of actions was so idly put forth as to make it rash to assert that intention had any part in them at all.  The waggoner's steps were heard returning.  She put the glass in the paper, and the whole again into its place.  When the waggon had passed on, Gabriel withdrew from his point of espial, and descending into the road, followed the vehicle to the turnpike-gate some way beyond the bottom of the hill, where the object of his contemplation now halted for the payment of toll.  About twenty steps still remained between him and the gate, when he heard a dispute.  It was a difference concerning twopence between the persons with the waggon and the man at the toll-bar.  "Mis'ess's niece is upon the top of the things, and she says that's enough that I've offered ye, you great miser, and she won't pay any more."  These were the waggoner's words.  "Very well; then mis'ess's niece can't pass," said the turnpike-keeper, closing the gate.  Oak looked from one to the other of the disputants, and fell into a reverie.  There was something in the tone of twopence remarkably insignificant.  Threepence had a definite value as money -- it was an appreciable infringement on a day's wages, and, as such, a higgling matter; but twopence -- "Here," he said, stepping forward and handing twopence to the gatekeeper; "let the young woman pass."  He looked up at her then; she heard his words, and looked down.  Gabriel's features adhered throughout their form so exactly to the middle line between the beauty of St. John and the ugliness of Judas Iscariot, as represented in a window of the church he attended, that not a single lineament could be selected and called worthy either of distinction or notoriety.  The red-jacketed and dark-haired maiden seemed to think so too, for she carelessly glanced over him, and told her man to drive on.

"And the greatest of them is -- well, what it is always." "Beating people down? ay, 'tis so." "O no." "What, then?" Gabriel, perhaps a little piqued by the comely traveller's indifference, glanced back to where he had witnessed her performance over the hedge, and said, "Vanity, dude."/
