1. NAVOD PRO PRACI S ANONYMNIM W3 KLIENTEM LYNX

Vladimir Vrabec, OMICRON


Pred nedavnem bylo ohlaseno uvedeni do provozu cesnetovskeho
anonymniho W3 klienta LYNX (telnet://www@public.vslib.cz). Pro
usnadneni prace s timto klientem, hlavne pro pocatecni uzivatele
site CESNet, je vypracovano toto kratke pojednani.


1.1. ZAKLADY PRACE

Lynx je urcen pro praci abecedne-cislicovych terminalu
s adresovatelnym kurzorem (napr. terminalu typu vt100 a jeho
emulatoru) s W3 (World Wide Web). Lynx jako klient zobrazuje HTML
(hypertext markup language) dokument obsahujici smerniky na jine
lokalni nebo vzdalene dokumenty. Tyto dokumenty mohou byt
umisteny na systemech pracujicich jako servery typu GOPHER, HTTP,
FTP, WAIS a NNTP. Soudobe verze klienta LYNX jsou implementovany
pro UNIX a VMS. Pripravuje se verze pro DOS.

LYNX po spusteni zobrazuje startovaci dokument, v pripade
naseho libereckeho anonymniho klienta je to domovska stranka
libereckeho W3 serveru. Zobrazeni je zahajeno smazanim stinitka
a prezentaci maximalni casti startovaciho dokumentu.

Lynx je urcen predevsim pro zobrazovani HTML souboru, coz
jsou soubory se zabudovanymi smerniky na dalsi soubory -
dokumenty. Pri zobrazovani jsou smerniky zvyraznovany, pricemz
jeden z nich, aktualne vybrany smernik, je zvyraznovan odlisnym
a napadnejsim zpusobem. Konkretni zpusoby zvyrazneni smerniku a
zobrazeni vybraneho smerniku zaviseji na typu pouziteho vstupniho
zarizeni.

Pohyb po dokumentu je pohybem po smernicich. Dosazeny
smernik se stava aktualne vybranym smernikem. Pri jeho aktivaci
klavesou "sipka vpravo" nebo klavesou RETURN LYNX pozada
prislusny server o jeho prenos a podobne jako v pripade
startovaciho dokumentu smaze stinitko a zobrazi maximalni cast
prenaseneho dokumentu. V anonymnim rezimu LYNX nepracuje
s binarnimi soubory - dokumenty. V beznem rezimu je prenasi a na
pokyn uzivatele je uklada na disk. Klavesa "sipka dolu" nebo
"TAB" slouzi k posunu na dalsi smernik. Neni-li na stinitku jiz
dalsi smernik, posune se dokument tak, ze na stinitku se zobrazi
dalsi cast dokumentu. Klavesa "sipka nahoru" slouzi k posunu na
predchozi smernik. Neni-li na stinitku predchozi smernik
a existuje-li predchozi cast dokumentu nezobrazena na stinitku,
posune se dokument tak, ze tato cast je zobrazena. Klavesa "sipka
vlevo" slozi k navratu na predchozi zobrazeny dokument,
samozrejme pokud existuje. Je-li z volitelnych vlastnosti klienta
LYNX nastavena vlastnost "VI Keys", tak klavesy malych pismen
"h", "j", "k", "l" jsou ekvivalentni klavesam "sipka vlevo",
"sipka dolu", "sipka nahoru" a "sipka vpravo". Klavesa "+" nebo
"mezera" slouzi k zobrazeni dalsi stranky smerem ke konci
dokumentu (PAGE DOWN). Klavesa "-" nebo "b" slozi k zobrazeni
predchozi stranky, tj. dalsi stranky smerem k pocatku dokumentu
(PAGE UP). Pri nastaveni "NUM LOCK" transformuje LYNX vyznam
klaves klavesnice "keypad" takto:

9 - "stranka nahoru" (PAGE UP)
8 - "sipka nahoru"
7 8 9 7 - "zobrazeni 1. stranky dokumentu"
\|/ 6 - "sipka vpravo"
4 - 5 - 6 5 - nic
/|\ 4 - "sipka vlevo"
1 2 3 3 - "stranka dolu" (PAGE DOWN)
2 - "sipka dolu"
1 - "zobrazeni posledni stranky dokumentu"

Jinou moznost pohybu po dokumentu a volbu smerniku poskytuje
volitelna vlastnost klienta LYNX "numbered links". Je-li
nastavena, tak smerniky jsou opatreny cisly a jejich volba je
provadena uvedenim prislusneho cisla. Implicitne vsak byva
nastavena alternativni vlastnost "keypad as arrows".

Pro uzivatele mimoradny vyznam maji prikazy vyvolavajici
"on-line help" a ukoncujici praci klienta LYNX.

Napovedu lze vyvolat klavesou "?" nebo klavesou "H".
Zakladnim dokumentem napovedy je dokument z kansaske univerzity
"http://kufacts.cc.ukans.edu/lynx_help/lynx_help_main.htm",
ktery nabizi volbu techto dalsich dokumentu napovedy:

Key-stroke commands
About Lynx
Lynx users guide version 2.3
Help on version 2.3
Help on HTML
HTML Quick Reference Guide
Help on URL's

Praci klienta lze ukoncit klavesami "q" nebo "Q". Pri
aktivaci klavesy "q" se klient taze uzivatele, zda opravdu chce
ukoncit praci. Odpovedi "y" uzivatel potvrzuje svuj zamer, pri
odpovedi "n" se pokracuje v praci na bezne strance zobrazovaneho
dokumentu. Pri pouziti prikazu "Q" se provadi ukonceni prace
okamzite bez overovani.

Pri prohlizeni dokumentu ve W3 klientem LYNX neni treba se
jen omezovat na pohyb po smernicich, ktere vedou od jednoho
dokumentu ke druhemu. Pokud klient nema blokovanou funkci
vyvolavanou klavesou "g", lze pomoci teto funkce pozadovat
aktivaci dokumentu specifikovaneho uzivatelem pomoci URL (Uniform
Resource Locator). Protoze tematice URL jsme se venovali
v OMICRON-ECHO-20 a OMICRON-ECHO-22, nebudeme se URL dale
zabyvat. Pripomenme pouze, ze po stisknuti klavesy "g" se nas
klient LYNX dotaze na URL dokumentu, ktery chceme zpristupnit.

Pri praci s klientem je udrzovana specialni struktura
(history list), do ktere se zaznamenavaji dokumenty, ktere byly
klientem LYNX uzivateli prezentovany. Pri vstupu do dokumentu, je
dokument zarazovan do teto struktury, pri vystupu z dokumentu
prostrednictvim prikazu "sipka vlevo", je dokument ze struktury
vyrazen. Zustava v ni pouze pri aktivaci dalsiho dokumentu
vyberem smerniku nebo specifikaci noveho URL. Vyberem polozky
z teto struktury lze se vratit k dokumentu, ktery byl jiz
uzivatelem vyvolan. Moznost pouzivat dalsi specialni strukturu
zvanou "zalozka" (bookmark file), nema pro anonymniho uzivatele
smysl a je v takovem pripade obvykle blokovana. Prikazem
vyvolavanym klavesou "i" je uzivateli davana moznost zobrazit si
dokument specifikovany pri instalaci nebo spusteni klienta
a obsahujici obvykle smerniky na dalsi zajimave dokumenty.
Liberecky klient vyvolava dokument INTERNET RESOURCES META-INDEX
"http://www.ncsa.uiuc.edu/SDG/Software/Mosaic/MetaINdex.html/".
Pro uplnost dodejme jeste, ze prikazem vyvolavanym klavesou "m"
se klient vraci na startovaci dokument.

Po stisknuti klavesy "p" se zobrazuje pomocne menu, ze
ktereho anonymni uzivatel vybira moznost poslat zobrazovany
dokument e-postou na specifikovanou e-adresu nebo moznost
zobrazit na stinitko bezny dokument v takove forme, v jake by byl
tisten na tiskarne. V pripade neanonymniho pouziti klienta LYNX
jsou uzivateli k dispozici i jine moznosti, napr. ulozeni bezneho
dokumentu do lokalniho souboru na disk.

Pro prohledavani jsou urceny dve funkce. Mame-li na stinitku
zobrazen normalni dokument, tak aktivaci klavesy "/" lze
vyhledavat v beznem dokumentu specifikovane slovo nebo
specifikovanou frazi. Ve volitelnych vlastnostech klienta lze
nastavit, zda pro vyhledavani je ci neni velikost pismen
podstatna. Pokud beznym dokumentem je dokument oznaceny jako
"indexovy dokument" (index document), tak vyhledavani dle
specifikovaneho klice nebo klicu se realizuje aktivaci klavesy
"s".

Nastavovani volitelnych vlastnosti klienta LYNX se umoznuje
stisknutim klavesy "o". Pak se zobrazi pomocne menu, z ktereho
pro anonymniho uzivatele maji prakticky vyznam pouze tyto
polozky:

E)ditor :
F)TP sort kriteria :By Filename
P)ersonal mail address :
S)earching type :CASE INSENSETIVE
V)I keys :OFF
e(M)acs keys :OFF
K)eypad as arrows or Numbered links :Numbers act as arrows
U)ser mode :Novice

Zmenu hodnot jednotlivych polozek lze dosahnout uvedenim
pocatecniho velkeho pismene radek polozek a specifikaci nove
hodnoty menene polozky. Klavesu "backspace" lze pouzit pri oprave
vstupu (mazani posledniho znaku) nebo stisknutim CTRL-U lze
vymazat celou vstupni radku. Zmena polozek, jejichz hodnoty jsou
prvky dane mnoziny hodnot, se provadi postupnou aktivaci
libovolne klavesy. Klavesou RETURN se zmena ukoncuje. Navrat z
funkce realizovane klavesou "o" se provadi aktivaci klavesy "r".
Jednotlive vyse uvedene polozky mohou nabyvat tyto hodnoty:

Editor
(specifikace editoru pro tvorbu vstupu pri neanonymnim uziti
klienta LYNX; neni-li specifikovan nebo LYNX pracuje v anonymnim
rezimu, pouziva se pro vstup obycejna radkova manipulace; vstup
se ukoncuje znakem "." na zacatku nove radky)

FTP sort kriteria - By Filename, By Size, By Type, By Date
(zpusob jak maji byt setrideny soubory ve FTP seznamu)

Personal mail address
(adresa, kam si uzivatel muze posilat prectene dokumenty)

Searching type - CASE INSENSITIVE, CASE SENSITIVE
(specifikace, zda velikost pismen je pri prohledavani podstatna
ci nikoliv)

VI keys - ON, OFF
(zda pismena "h", "j", "k" a "l" se mapuji jako "sipka vlevo",
"sipka dolu", "sipka nahoru" a "sipka vpravo" ci nikoliv)

Emacs keys - ON, OFF
(zda CTRL-P, CTRL-N, CTRL-F a CTRL-B se mapuji jako "sipka
nahoru", "sipka dolu", "sipka vpravo" a "sipka vlevo" ci nikoliv)

Keypad as arrows or numbered links
(moznost vybirat smerniky klavesami se sipkami nebo vybirat je
dle prirazenych cisel)

User Mode - Novice, Intermediate, Advanced
(pri volbe "Novice" se zobrazuji na konci stranky stinitka dva
radky s napovedou, pri volbe "Intermediate" se radky s napovedou
nezobrazuji a pri volbe "Advanced" se na konci stranky stinitka
zobrazuje URL pro aktualni smernik).

V libovolnem okamziku prohlizeni dokumentu lze pouzit prikaz
"c", s jehoz pomoci muze uzivatel zaslat vlastniku dokumentu
e-dopis, pokud autor dokumentu vlastnictvi specifikoval. Neni-li
vlastnictvi definovano, je prikaz neucinny. Rovnez smerniky typu
"mailto:" poskytuji moznost poslat e-dopis urcenym osobam.

V obou pripadech LYNX predlozi uzivateli novou stranku
s informaci, komu se bude e-dopis posilat. Pak je uzivatel
dotazan na sve jmeno, dale na svou e-adresu, pokud nebyla
specifikovana v polozce "personal mail address", na predmet
(SUBJECT) e-dopisu. Nato uzivatel zapise text e-dopisu. LYNX
pozada o souhlas s odeslanim. Odpovi-li uzivatel klavesou "y", je
dopis odeslan, odpovi-li klavesou "n", je dopis zrusen.

Pri cetbe clanku USENET NEWS klientem LYNX jsou definovany
dva smerniky oznacovane "Reply to user at host" a "Reply to
newsgroup(s)". Aktivace prveho smerniku umoznuje zaslat e-postou
pripominku autorovi clanku (autorova e-adresa je user at host).
Druhy smernik slouzi k zaslani pripominky k clanku primo do
USENET NEWS.

Prikazem vyvolanym klavesou "\" lze zobrazit na stinitku
zdrojovy tvar (HTML tvar) bezneho dokumentu. Klavesou "=" se
uzivateli prezentuji informace o beznem dokumentu (pocet radku,
URL, titul, vlastnik, typ dokumentu). Klavesou "z" se muze
navazovani spojeni nebo prenos dokumentu zastavit. Data prenesena
do stisknuti klavesy "z" jsou klientem uzivateli na stinitku
zobrazena. CTRL-R znovu zavede bezny dokument na stinitko,
CTRL-W stinitko vymaze, CTRL-U vymaze text z pole pro vstup,
CTRL-G rusi vstup, e-dopis nebo prenos dat.

Pri spousteni klienta LYNX mohou byt prislusnymi parametry
nastaveny nebo potlaceny nektere jeho vlastnosti nebo funkce. Pri
spousteni v anonymnim rezimu byva potlacena vetsina jeho
volitelnych funkci.

1.4.2 GENERAL OVERVIEW OF THE WEB

Overview of the Web
GENERAL OVERVIEW OF THE WEB

There is no "top" to the World-Wide Web. You can look at it
from many points of view. Here are some places to start.

by Subject[1] The Virtual Library organises information by
subject matter.

List of servers[2] All registered HTTP servers by country

by Service Type[3] The Web includes data accessible by many
other protocols. The lists by access protocol may help if you
know what kind of service you are looking for.

If you find a useful starting point for you personally, you
can configure your WWW browser to start there by default.
