INNER {returnImm {Unknow state transition: LINE -> END} {}} CALL {my render_wikit Rivet \[http://tcl.apache.org/rivet/Rivetlogo_small.png\]\n\n\[Apache\]\ Rivet\ is\ the\ next\ generation\ of\ \[mod_dtcl\]\ and\ \[NeoWebScript\],\ combined:\n\"like\ \[PHP\],\ but\ with\ \[Tcl\].\"\ \ More\ info\ appears\ at\ http://tcl.apache.org/rivet/\n\nWas\ this\ made\ by\ the\ same\ people\ as\ NWS\ and\ mod_dtcl,\ or\ is\ it\ a\ separate\ team\ of\ developers?\ \ -\[FW\]\n\nCurrent\ developers\ on\ Rivet\ are\ \[Massimo\ Manghi\],\ \[Harald\ Oehlmann\],\ \[Karl\ Lehenbauer\]\ and\ sometimes\ \[David\ Welton\].\ \ \[Damon\ Courtney\],\ \[Brad\ Morrison\],\ \[Pat\ Thoyts\]\ and\ \[Andy\ Doerr\]\ have\ all\ greatly\ contributed\ in\ the\ past.\n\nThere\ is\ a\ Windows\ binary\ version\ for\ Apache\ (not\ Apache2)\ here:\ http://www.apache.mirrors.versehost.com/tcl/rivet/binary/\n\nhttp://tcl.apache.org/rivet/static/rn-2-1.html%|%Rivet\ 2.1.4%|%\ released.\ \n\nUbuntu\ has\ Rivet\ in\ its\ repositories\ but\ it\ might\ be\ necessary\ to\ change\ mpm-event\ to\ mpm-prefork\ in\ apache\ config\ (mods\ enabled)\n\n----\nTry\ \[THP\]\ as\ an\ alternative.\ \ A\ webserver\ neutral\ way\ to\ embed\ Tcl\ code.\ --\[CAU\]\n\n----\nCan\ we\ have\ some\ testimonials\ by\ Rivet\ users?\ \ (sorry,\ i'm\ new\ to\ servers\ in\ general)\n\n\ \ \ 1.\ how\ do\ you\ connect\ to\ a\ db,\ tcl\ db\ extensions?\n\ \ \ 2.\ is\ an\ apache\ instance\ with\ rivet\ and\ tomcat\ possible?\ encouraged?\n\ \ \ 3.\ mod_rewrite\ in\ the\ midst\ of\ all\ this,\ or\ is\ that\ only\ available\ on\ top\ of\ a\ tomcat\ instance?\n\ \ \ 4.\ are\ importing\ libraries\ like\ \[tcllib\]\ a\ piece\ of\ cake\ after\ rivets\ installed?\n\n\ni\ want\ to\ run\ a\ dual\ \[java\]/tcl\ environment...\n\n----\n\[davidw\]\ -\ I\ think\ these\ questions\ are\ more\ appropriate\ for\ the\ newsgroup\ or\ the\ rivet\ mailing\ list,\ but\ I'll\ give\ it\ a\ shot:\n\n1)\ You\ use\ regular\ Tcl\ database\ extensions.\ \ Rivet\ is\ pretty\ much\ standard\ Tcl,\ making\ a\ lot\ of\ the\ code\ you\ write\ for\ it\ reusable\ on\ or\ off\ the\ web.\n\n2)\ I've\ never\ mixed\ Apache\ and\ Tomcat.\ \ I\ don't\ really\ care\ for\ Java\ for\ these\ sorts\ of\ things\ unless\ you\ have\ a\ *big*\ infrastructure,\ and\ that's\ not\ something\ I've\ dealt\ with\ a\ lot.\n\n3)\ mod_rewrite\ is\ an\ Apache\ thing\ and\ it\ works\ just\ fine\ with\ Rivet.\ \ In\ fact,\ it's\ encouraged\ if\ you\ want\ to\ do\ things\ like\ have\ one\ rivet\ script\ respond\ to\ a\ whole\ virtual\ directory\ tree.\ \ So\ /foo/bar/\ /foo/baz/\ /foo/bee/bop\ and\ so\ forth\ are\ all\ mapped\ to\ foo.tcl?bar\ foo.tcl?baz\ foo?bee+bop\ and\ so\ forth.\n\n4)\ tcllib\ and\ other\ libs\ are\ a\ piece\ of\ cake:-)\n\n----\nAbout\ Rivet's\ mailing\ list,\ \[http://tcl.apache.org/rivet/about.rvt\]\ says:\ \"This\ list\ is\ archived\ here:\ \[http://mail-archives.apache.org/eyebrowse/SummarizeList?listId=118\]\".\ But\ leads\ to\ an\ error:\ \"Required\ parameter\ 'listId'\ or\ 'listName'\ is\ missing\ or\ invalid\".\n\n\[JJR\]:\ The\ mailing\ list\ archives\ for\ the\ tcl\ apache\ projects\ can\ be\ found\ at\ \[http://mail-archives.apache.org/mod_mbox/#tcl\]\ .\n\n----\nRivet\ \"lets\ you\ program\ in\ not\ only\ mixed\ HTML/Tcl,\ but\ also\ pure\ Tcl,\ which\nis\ good\ for\ separating\ content\ and\ presentation.\"\n\n----\n\[RLH\]:\ Are\ there\ any\ Rivet\ tutorials\ mucking\ about?\n\n\[Massimo\ Manghi\]:\ Rivet\ manuals\ have\ examples\ for\ both\ configuration\ and\ programming.\ Rivet\ extends\ Tcl\ with\ a\ small\ set\ of\ new\ commands\ dedicated\ to\ web\ programming\ and\ therefore\ having\ a\ good\ Tcl\ manual\ can\ be\ useful,\ depending\ on\ the\ familiarity\ of\ the\ developer\ with\ the\ language.\n\n----\n\[davidw\]:\ Not\ yet,\ but\ Rivet\ is\ very\ similar\ to\ plain\ old\ Tcl,\ and\ the\ differences\ are\ covered\ in\ the\ documentation.\n\nAs\ far\ as\ programming\ style,\ if\ you\ are\ doing\ something\ simple...\ just\ go\ ahead\ and\ mix\ your\ HTML\ and\ Tcl\ code.\ \ If\ it's\ a\ more\ complex\ app,\ separate\ things\ out\ into\ .tcl\ files\ that\ act\ as\ the\ logic\ and\ use\ .rvt\ files\ simply\ as\ templates.\n\nOr\ write\ the\ mailing\ list\ for\ more\ specific\ questions...\n\n\[RLH\]:\ I\ am\ looking\ for\ something\ similiar\ to\ HTML::Template\ \[http://html-template.sourceforge.net/article.html\]\ from\ the\ Perl\ side\ of\ the\ house.\ I\ like\ the\ clean\ separation\ of\ code\ and\ HTML.\ \ :\ )\n\n----\nThat\ perl\ template\ stuff\ just\ adds\ funny\ tags,\ which\ are\ not\ standard\ HTML.\ \ If\ you\ want\ to\ separate\ code\ and\ templates,\ do\ your\ processing\ in\ a\ .tcl\ file,\ then\ do\ \"parse\ foo.rvt\",\ and\ in\ the\ .rvt\ file,\ put\ statements\ like\ <?\ puts\ \$foo\ ?>\ <?\ puts\ \$bar?>\ where\ you\ need\ variable\ values.\ \ Or\ if\ you\ really\ wanted\ to\ do\ something\ fancy,\ you\ could\ call\ the\ parse.rvt\ in\ its\ own\ namespace/interpreter/whatever\ from\ the\ .tcl\ file,\ and\ create\ procs\ that\ are\ aliases\ to\ your\ variables,\ so\ all\ you\ have\ to\ do\ is\ <?foo?>\ <?bar?>\ in\ order\ to\ get\ output.\ \ I\ suppose\ a\ standardized\ way\ of\ doing\ this\ would\ be\ nice,\ but\ it\ is\ pretty\ easy...\ experiment\ and\ tell\ us\ (on\ the\ list,\ please)\ what\ you\ end\ up\ liking!\n\n\[RLH\]:\ You\ are\ correct\ about\ the\ funny\ tags,\ I\ meant\ more\ of\ a\ \"standard\ way\ of\ doing\ this...\"\ as\ you\ said.\ I\ will\ go\ with\ your\ suggestions.\ I\ am\ far\ from\ good\ enough\ to\ create\ the\ \"standard\ way\"\ though.\ \ :\ )\n\n----\n\[RLH\]\ 2006-02-07:\ Are\ there\ any\ hosting\ companies\ that\ support\ Rivet?\n\n\[Roy\ Keene\]\ 2008-10-06:\ Any\ Rivet\ application\ can\ be\ turned\ into\ an\ HTTP/CGI\ application.\ \ And\ with\ Starpacks\ the\ entire\ thing\ can\ be\ completely\ self-contained\ in\ one\ file.\n\n----\n\[APW\]\ 2007-01-20:\ if\ you\ have\ problems\ installing\ \[Tcl\ and\ Rivet\ on\ Windows\]\ follow\ the\ link.\n\n----\n\[Roy\ Keene\]\ 2008-10-05:\ Rivet\ can\ also\ be\ implemented\ transparently\ using\ CGI.\ \ This\ has\ the\ advantage\ of\ using\ \"suEXEC\"\ and\ working\ well\ with\ all\ versions\ of\ Apache.\ More\ information\ can\ be\ found\ on\ the\ Rivet/CGI\ page\ (\[http://www.rkeene.org/projects/info/wiki/51\])\n\n\[Roy\ Keene\]\ 2009-03-20:\ Rivet/CGI\ (\[http://www.rkeene.org/projects/info/wiki/51\])\ now\ supports\

abnormal\ condition\ you\ are\ catching\ somehow\ in\ your\ code\ you\ may\ call\ 'abort_page\ <abort_code>'\ which\ will\ trigger\ the\ code\ set\ up\ in\ AbortScript.\ Within\ this\ script\ you\ can\ check\ which\ condition\ brought\ about\ the\ error\ using\ the\ 'abort_code'\ command\ that\ is\ supposed\ to\ return\ the\ <abort_code>\ you\ passed\ when\ you\ fired\ the\ exception.\n\nSee\ also\ the\ 'headers'\ and\ 'no_body'\ commands\n\nSurely\ you\ can\ design\ your\ own\ error\ page\ if\ you\ want.\ It\ should\ imply\ some\ extra\ work\ but\ greater\ flexibility\n\nDid\ you\ check\

Tcl\ database\ extensions.\ \ Rivet\ is\ pretty\ much\ standard\ Tcl,\ making\ a\ lot\ of\ the\ code\ you\ write\ for\ it\ reusable\ on\ or\ off\ the\ web.\n\n2)\ I've\ never\ mixed\ Apache\ and\ Tomcat.\ \ I\ don't\ really\ care\ for\ Java\ for\ these\ sorts\ of\ things\ unless\ you\ have\ a\ *big*\ infrastructure,\ and\ that's\ not\ something\ I've\ dealt\ with\ a\ lot.\n\n3)\ mod_rewrite\ is\ an\ Apache\ thing\ and\ it\ works\ just\ fine\ with\ Rivet.\ \ In\ fact,\ it's\ encouraged\ if\ you\ want\ to\ do\ things\ like\ have\ one\ rivet\ script\ respond\ to\ a\ whole\ virtual\ directory\ tree.\ \ So\ /foo/bar/\ /foo/baz/\ /foo/bee/bop\ and\ so\ forth\ are\ all\ mapped\ to\ foo.tcl?bar\ foo.tcl?baz\ foo?bee+bop\ and\ so\ forth.\n\n4)\ tcllib\ and\ other\ libs\ are\ a\ piece\ of\ cake:-)\n\n----\nAbout\ Rivet's\ mailing\ list,\ \[http://tcl.apache.org/rivet/about.rvt\]\ says:\ \"This\ list\ is\ archived\ here:\

manuals\ have\ examples\ for\ both\ configuration\ and\ programming.\ Rivet\ extends\ Tcl\ with\ a\ small\ set\ of\ new\ commands\ dedicated\ to\ web\ programming\ and\ therefore\ having\ a\ good\ Tcl\ manual\ can\ be\ useful,\ depending\ on\ the\ familiarity\ of\ the\ developer\ with\ the\ language.\n\n----\n\[davidw\]:\ Not\ yet,\ but\ Rivet\ is\ very\ similar\ to\ plain\ old\ Tcl,\ and\ the\ differences\ are\ covered\ in\ the\ documentation.\n\nAs\ far\ as\ programming\ style,\ if\ you\ are\ doing\ something\ simple...\ just\ go\ ahead\ and\ mix\ your\ HTML\ and\ Tcl\ code.\ \ If\ it's\ a\ more\ complex\ app,\ separate\ things\ out\ into\ .tcl\ files\ that\ act\ as\ the\ logic\ and\ use\ .rvt\ files\ simply\ as\ templates.\n\nOr\ write\ the\ mailing\ list\ for\ more\ specific\ questions...\n\n\[RLH\]:\ I\ am\ looking\ for\ something\ similiar\ to\ HTML::Template\ \[http://html-template.sourceforge.net/article.html\]\ from\ the\ Perl\ side\ of\ the\ house.\ I\ like\ the\ clean\ separation\ of\ code\ and\ HTML.\ \ :\ )\n\n----\nThat\ perl\ template\ stuff\ just\ adds\ funny\ tags,\ which\ are\ not\ standard\ HTML.\ \ If\ you\ want\ to\ separate\ code\ and\ templates,\ do\ your\ processing\ in\ a\ .tcl\ file,\ then\ do\ \"parse\ foo.rvt\",\ and\ in\ the\ .rvt\ file,\ put\ statements\ like\ <?\ puts\ \$foo\ ?>\ <?\ puts\ \$bar?>\ where\ you\ need\ variable\ values.\ \ Or\ if\ you\ really\ wanted\ to\ do\ something\ fancy,\ you\ could\ call\ the\ parse.rvt\ in\ its\ own\ namespace/interpreter/whatever\ from\ the\ .tcl\ file,\ and\ create\ procs\ that\ are\ aliases\ to\ your\ variables,\ so\ all\ you\ have\ to\ do\ is\ <?foo?>\ <?bar?>\ in\ order\ to\ get\ output.\ \ I\ suppose\ a\ standardized\ way\ of\ doing\ this\ would\ be\ nice,\ but\ it\ is\ pretty\ easy...\ experiment\ and\ tell\ us\ (on\ the\ list,\ please)\ what\ you\ end\ up\ liking!\n\n\[RLH\]:\ You\ are\ correct\ about\ the\ funny\ tags,\ I\ meant\ more\ of\ a\ \"standard\ way\ of\
