Facilitating <fo:block span="all"> -FOTEX.XMT -in \XMLelement{fo:block}: detect the span="all" attribute and if so, end -multicol layout before (if present), and resume multicol layout (if there -was one) after. -FOTEX.STY -new user-interface macros for loading nomulticols.sty if present, otherwise -resorting to multicols, if present, otherwise defining a fake multicols -environment. If nomulticols could not be loaded, care is taken that fo:block -span="all" is disabled, otherwise the TeX run will fail. -In \@outputpage, call refreshmulticols, which will possibly refresh the -multicol layout. -NOMULTICOL.STY -new file, same functionality as MULTICOL.STY, but does not use an -environment. With some extra macros to interrupt a multicolumnlayout. It is -now possible to say - -begin multicol layout - start group - *1* - start group - end multicol layout *2* - start group - do something interesting - end group - begin multicol layout *4* - end group - *3* - end group -end multicol layout - -CAVEAT 1: a lot of assignments of nomulticol have been made global, may be -too much. For example, if something is set at point *1*, it should be -restored at point *3*, but if this thing is also set by nomulticol, it will -undergo a global change at point *2* and/or *4*, and hence will not be -restored by TeX's grouping mechanism anymore. -So may be it is needed to carefully discriminate between counts, dimens, -boxes, and macros that are particular to multicol (the should be treated -wholly globally), and the (La)TeX-quantities that are dependent on them, and -they might be set locally. - -CAVEAT 2: care must be taken that nomulticol interacts well with an other -change by me: every time a page is output, a fresh page setup will be -computed, if necessary. After this page setup, the multicol environment must -be refreshed (if it was in force). But refreshing should not occur twice in -a row for the same page. Although it seems that I have succeeded in -preventing this double refreshment, I still wonder why it can occur at the -first place. -2. Facilitating multiple special pages -XSL-FO facilitates the specification of a sequence of special pages before -an unbounded, repeating page sequence starts. -PassiveTeX only allowed one special page, labelled First. I allow for the -definition of a sequence of such pages, labelled Lead<counter>. In \@output -page a counter keeps track of which Lead page should be set up. A page setup -will be done if necessary. -This change interacts with multicol, see previous item. -Note also, that blank pages, caused by explicit page-breaks of number -continuating properties, will be detected as blank pages, and hence react to -the blank-or-not-blank attribute. -3. Implementation of xsl-footnote-separator -A rather crude implementation, by storing the static content of -xsl-footnote-separator in the macro \footnoterule, and adjusting the -\skip\footins too match the height+ depth of the new \footnoterule. -4. Enabling footnotes in tables -Footnotes in tables work. This is done by saving footnotes insides tables -into a tokenlist \BoxedFootnotes, doing the corresponding \insert-s at the -end of the table. - -CAVEAT: this is not reallly a nice implementation: if the table breaks -across pages, the footnotetexts will not appear on the same page as the -footnotemarks. -5. Vertical align in tables -If I work with an explicit line-height, the vertical space allocation for -the first and last row of a table comes out wrong. Also, when there is a -line-break inside a cell, the cell-height comes out too small. Something -gets discarded. I have made some changes to the interlineskip (following the -TeXBook definition of \offinterlineskip), in order to fix this, but I have -not succeeded completely. -6. Inheriting table-cell properties from table-column -According to XSL-FO table-cells my inherit properties from corresponding -table-columns by using -att-x="from-column(att-x)" -PassiveTeX only implements inheritance of column-width and column-number, -without the need to use from-column("column-width"). -I have made only an adhoc improvement: text-align will be inherited from the -column, and it happens automatically, without using from-column(text-align). -I have done this with the Array implementation, used for column-width and -column-number. More properties can added easily. It should not be too -difficult to implement from-column(att-x) for a fixed set of attributes, but -implementing this for all possible attributes is more difficult. -7. vskip vs kern -In the code for typesetting blocks, I have changed some vskips in kern, -because I trust the kern better than te vskip (kerns will not be discarded, -vskips might be, and I am not completely sure about the conditions). -8. Bug in FOBoxedBlock -There is some weird code at the start of \FOBoxedBlock (see comments in -fotex.sty at that point). -I have also added some \relax calls after assignments to be sure that the -text after \fi etc is not gobbled up by the preceding assignment. -9. Percenttests -I have increased the use of percented attribute values. Also, \percenttest -was not always able to see the % character, because it was still unexpanded -when fed to it. I have changed that, so that any percent in the -attributetext is surely expanded to a % with catcode 12 before being fed to -percenttest. -(Mostly % appears as an active char, and by means of a limitied-scope -definition of % to be % with catcode 12, this case will be brought to meet -the assumption). -10. Overline -I have added the overline formatting for inlines, but not nearly as nice as -the underline of ulem.sty. I just needed it in simple cases, so I took the -easy option. -11. Pagenumber filtering -The algorithm to filter page number sequences generated by indexes (a very -nice feature of passivetex, by the way), had a few obvious mistakes. I have -corrected them. -12. Horizontal alignment -There were still some problems with alignment, I made some corrections to -\FOOutputblock in fotex.sty. -See also mlnames.sty, definition of \Q@end -13 Page breaks -In \FONormalBlcok I found that a \penalty -\@M did not generate a page -break, so I changed it to \newpage (a few times). (see also changes in -\FOEndBlockTwo -14 Sub- Superscript -PassiveTeX adjusted the fontsize of sub/superscripts, but this should be -governed by the fo-tree. -So I adjusted \textsub/superscript in fotex.sty -15 Dimensions of the page -Page dimensions now work additive, more according to the XSL-FO spec. -16 attribute="inherit" -Now the inherit mechanism can also be triggered by the explicit value of -"inherit". This was achieved by redefining a macro of xmltex: \XML@attrib@x -(in fotex.xmt) -17. fo:external-graphic -scale-to-fit behaviour modified: scaled to the local container instead of -the page (hsize, vsize instead of linewidth, textheight) -18. fo:leader implemetation improved -The code for fo:leader in xmt has been improved -19. fo-retrieve-marker -Some trivial improvements in the code of fo:retrieve-marker -20. More unicode characters -Added definitions for unicode   and   (em and n squares) in -ucharacters.sty -A. Nested fo:block in fo:table-cell -Something goes wrong with <fo:table-cell><fo:block><fo:block>. -The count \FOinTable records whether we are inside a table.

Some years ago—never mind how long -precisely —having little or no money in my purse, and nothing -particular to interest me on shore, I thought I would sail about a -little and see the watery part of the world. It is a way I have of -driving off the spleen, and regulating the circulation. Whenever I -find myself growing grim about the mouth; whenever it is a damp, -drizzly November in my soul; whenever I find myself involuntarily -pausing before coffin warehouses, and bringing up the rear of every -funeral I meet; and especially whenever my hypos get such an upper -hand of me, that it requires a strong moral principle to prevent me -from deliberately stepping into the street, and methodically knocking -people's hats off—then, I account it high time to get to sea as -soon as I can. This is my substitute for pistol and ball. With a -philosophical flourish Cato throws himself upon his sword; I quietly -take to the ship. There is nothing surprising in this. If they but -knew it, almost all men in their degree, some time or other, cherish -very nearly the same feelings towards the ocean with me. There now is -your insular city of the Manhattoes, belted round by wharves as Indian -isles by coral reefs—commerce surrounds it with her surf. Right -and left, the streets take you waterward. Its extreme down-town is -the battery, where that noble mole is washed by waves, and cooled by -breezes, which a few hours previous were out of sight of land. Look -at the crowds of water-gazers there. Circumambulate the city of a -dreamy Sabbath afternoon. Go from Corlears Hook to Coenties Slip, and -from thence, by Whitehall northward. What do you see?—Posted -like silent sentinels all around the town, stand thousands upon -thousands of mortal men fixed in ocean reveries. Some leaning against -the spiles; some seated upon the pier-heads; some looking over the -bulwarks glasses! of ships from China; some high aloft in the -rigging, as if striving to get a still better seaward peep. But these -are all landsmen; of week days pent up in lath and plaster—tied -to counters, nailed to benches, clinched to desks. How then is this? -Are the green fields gone? What do they here? But look! here come -more crowds, pacing straight for the water, and seemingly bound for a -dive. Strange! Nothing will content them but the extremest limit of -the land; loitering under the shady lee of yonder warehouses will not -suffice. No. They must get just as nigh the water as they possibly -can without falling in. And there they stand—miles of -them—leagues. </p> - -<p> Inlanders all, they come from lanes and alleys, streets and -avenues, —north, east, south, and west. Yet here they all -unite. Tell me, does the magnetic virtue of the needles of the -compasses of all those ships attract them thither? Once more. Say, -you are in the country; in some high land of lakes. Take almost any -path you please, and ten to one it carries you down in a dale, and -leaves you there by a pool in the stream. There is magic in it. Let -the most absent-minded of men be plunged in his deepest -reveries—stand that man on his legs, set his feet a-going, and -he will infallibly lead you to water, if water there be in all that -region. Should you ever be athirst in the great American desert, try -this experiment, if your caravan happen to be supplied with a -metaphysical professor. Yes, as every one knows, meditation and water -are wedded for ever. - But here is an artist. He desires to paint you the dreamiest, -shadiest, quietest, most enchanting bit of romantic landscape in all -the valley of the Saco. What is the chief element he employs? There -stand his trees, each with a hollow trunk, as if a hermit and a -crucifix were within; and here sleeps his meadow, and there sleep his -cattle; and up from yonder cottage goes a sleepy smoke. Deep into -distant woodlands winds a mazy way, reaching to overlapping spurs of -mountains bathed in their hill-side blue. But though the picture lies -thus tranced, and though this pine-tree shakes down its sighs like -leaves upon this shepherd's head, yet all were vain, unless the -shepherd's eye were fixed upon the magic stream before him. Go visit -the Prairies in June, when for scores on scores of miles you wade -knee-deep among Tiger-lilies—what is the one charm wanting? -—Water —there is not a drop of water there! Were Niagara -but a cataract of sand, would you travel your thousand miles to see -it? Why did the poor poet of Tennessee, upon suddenly receiving two -handfuls of silver, deliberate whether to buy him a coat, which he -sadly needed, or invest his money in a pedestrian trip to Rockaway -Beach? Why is almost every robust healthy boy with a robust healthy -soul in him, at some time or other crazy to go to sea? Why upon your -first voyage as a passenger, did you yourself feel such a mystical -vibration, when first told that you and your ship were now out of -sight of land? Why did the old Persians hold the sea holy? Why did -the Greeks give it a separate deity, and own brother of Jove? Surely -all this is not without meaning. And still deeper the meaning of that -story of Narcissus, who because he could not grasp the tormenting, -mild image he saw in the fountain, plunged into it and was drowned. -But that same image, we ourselves see in all rivers and oceans. It is -the image of the ungraspable phantom of life; and this is the key to -it all. Now, when I say that I am in the habit of going to sea -whenever I begin to grow hazy about the eyes, and begin to be over -conscious of my lungs, I do not mean to have it inferred that I ever -go to sea as a passenger. For to go as a passenger you must needs -have a purse, and a purse is but a rag unless you have something in -it. Besides, passengers get sea-sick —grow quarrelsome -—don't sleep of nights —do not enjoy themselves much, as a -general thing; —no, I never go as a passenger; nor, though I am -something of a salt, do I ever go to sea as a Commodore, or a Captain, -or a Cook. I abandon the glory and distinction of such offices to -those who like them. For my part, I abominate all honorable -respectable toils, trials, and tribulations of every kind whatsoever. -It is quite as much as I can do to take care of myself, without taking -care of ships, barques, brigs, schooners, and what not. And as for -going as cook, — though I confess there is considerable glory in -that, a cook being a sort of officer on ship-board —yet, -somehow, I never fancied broiling fowls; —though once broiled, -judiciously buttered, and judgmatically salted and peppered, there is -no one who will speak more respectfully, not to say reverentially, of -a broiled fowl than I will. It is out of the idolatrous dotings of -the old Egyptians upon broiled ibis and roasted river horse, that you -see the mummies of those creatures in their huge bake-houses the -pyramids. No, when I go to sea, I go as a simple sailor, right before -the mast, plumb down into the forecastle, aloft there to the royal -mast-head. True, they rather order me about some, and make me jump -from spar to spar, like a grasshopper in a May meadow. And at first, -this sort of thing is unpleasant enough. It touches one's sense of -honor, particularly if you come of an old established family in the -land, the van Rensselaers, or Randolphs, or Hardicanutes. And more -than all, if just previous to putting your hand into the tar-pot, you -have been lording it as a country schoolmaster, making the tallest -boys stand in awe of you. The transition is a keen one, I assure you, -from the schoolmaster to a sailor, and requires a strong decoction of -Seneca and the Stoics to enable you to grin and bear it. But even -this wears off in time. What of it, if some old hunks of a -sea-captain orders me to get a broom and sweep down the decks? What -does that indignity amount to, weighed, I mean, in the scales of the -New Testament? Do you think the archangel Gabriel thinks anything the -less of me, - because I promptly and respectfully obey that old hunks in that -particular instance? Who aint a slave? Tell me that. Well, then, -however the old sea-captains may order me about—however they may -thump and punch me about, I have the satisfaction of knowing that it -is all right; that everybody else is one way or other served in much -the same way — either in a physical or metaphysical point of -view, that is; and so the universal thump is passed round, and all -hands should rub each other's shoulder-blades, and be content. Again, -I always go to sea as a sailor, because they make a point of paying me -for my trouble, whereas they never pay passengers a single penny that -I ever heard of. On the contrary, passengers themselves must pay. -And there is all the difference in the world between paying and being -paid. The act of paying is perhaps the most uncomfortable infliction -that the two orchard thieves entailed upon us. But being paid, -—what will compare with it? The urbane activity with which a -man receives money is really marvellous, considering that we so -earnestly believe money to be the root of all earthly ills, and that -on no account can a monied man enter heaven. Ah! how cheerfully we -consign ourselves to perdition! Finally, I always go to sea as a -sailor, because of the wholesome exercise and pure air of the -forecastle deck. For as in this world, head winds are far more -prevalent than winds from astern (that is, if you never violate the -Pythagorean maxim), so for the most part the Commodore on the -quarter-deck gets his atmosphere at second hand from the sailors on -the forecastle. He thinks he breathes it first; but not so. In much -the same way do the commonalty lead their leaders in many other -things, at the same time that the leaders little suspect it. But -wherefore it was that after having repeatedly smelt the sea as a -merchant sailor, I should now take it into my head to go on a whaling -voyage; this the invisible police officer of the Fates, who has the -constant surveillance of me, and secretly dogs me, and influences me -in some unaccountable way —he can better answer than any one -else. And, doubtless, my going on this whaling - voyage, formed part of the grand programme of Providence that was drawn up a -long time ago. It came in as a sort of brief interlude and solo between more -extensive performances. I take it that this part of the bill must have run -something like this: -<list> -<item>Grand Contested Election for the Presidency of the -United States. </item> -<item>Whaling Voyage by one Ishmael. </item> -<item>Bloody Battle in Affghanistan.</item> -</list>Though I cannot tell why it was exactly that those stage -managers, the Fates, put me down for this shabby part of a whaling voyage, -when others were set down for magnificent parts in high tragedies, and short -and easy parts in genteel comedies, and jolly parts in farces —though I -cannot tell why this was exactly; yet, now that I recall all the -circumstances, I think I can see a little into the springs and motives which -being cunningly presented to me under various disguises, induced me to set -about -performing the part I did, besides cajoling me into the delusion that it was -a choice resulting from my own unbiased freewill and discriminating judgment. -chief among these motives was the overwhelming idea of the great whale -himself. Such a portentous and mysterious monster roused all my curiosity. -Then the wild and distant seas where he rolled his island bulk; the -undeliverable, nameless perils of the whale; these, with all the attending -marvels of a thousand Patagonian sights and sounds, helped to sway me to my -wish. With other men, perhaps, such things would not have been inducements; -but as for me, I am tormented with an everlasting itch for things remote. I -love to sail forbidden seas, and land on barbarous coasts. Not ignoring what -is good, I am quick to perceive a horror, and could still be social with -it—would they let me —since it is but well to be on friendly terms with all -the inmates of the place one lodges in. By reason of these things, then, the -whaling voyage was welcome; the great flood-gates of the wonder-world swung -open, and in the wild conceits that swayed me to my purpose, two and two -there floated into my inmost soul, endless processions of the whale, and, mid -most of them all, one grand hooded phantom, like a snow hill in the air. -</p> -</div> -</body> -</text> -</TEI.2> diff --git a/Master/texmf-dist/doc/xmltex/passivetex/xsa.xml b/Master/texmf-dist/doc/xmltex/passivetex/xsa.xml deleted file mode 100644 index df46cbc7896..00000000000 --- a/Master/texmf-dist/doc/xmltex/passivetex/xsa.xml +++ /dev/null @@ -1,14 +0,0 @@ -<xsa version="1.0"> - <vendor> - <name>Sebastian Rahtz</name> - <email>sebastian.rahtz@oucs.ox.ac.uk</email> - </vendor> - <product id="fotex"> - <name>Passive TeX</name> - <version>1.3, 10th December 2000</version> - <last-release>20001210</last-release> - <info-url>http://users.ox.ac.uk/~rahtz/passivetex/</info-url> - </product> -</xsa> - - |
