Ukuvuselelwa kwesithupha kolimi lohlelo lweRuby 2.6.0 lapha

Ngemuva konyaka wentuthuko, kukhishwa ukukhishwa kweRuby 2.6.0, ulimi oluhlelayo oluqondiswe entweni, olubonakala ngokusebenza kahle kokuthuthuka kwesoftware nokufaka izici ezinhle kakhulu zePerl, iJava, iPython, iSalltalk, i-Eiffel, i-Ada neLisp.

Ikhodi yephrojekthi isatshalaliswa ngaphansi kwamalayisense e-BSD ("Isigatshana esingu-2 BSDL") ne- "Ruby", esho ilayisense lakamuva le-GPL futhi ihambisana ngokuphelele ne-GPLv3.

URuby 2.6 inguqulo yesithupha enkulu, ilungiswe njengengxenye yenqubo yentuthuko ehleliwe, okubandakanya ukwabiwa konyaka ukulungiselela ukuthuthukiswa kokusebenza nokwenza izinguqulo zokulungisa njalo ezinyangeni ezi-2-3.

Izici ezintsha eziyinhloko kuRuby 2.6.0

Ngalokhu kukhishwa okusha kukaRuby ungeze ukuqaliswa kokuhlola komhlanganisi we-JIT, okukuvumela ukuthi uthuthukise kakhulu ukusebenza kwezicelo ngolimi lweRuby.

Ngokungafani nabahlanganisi bendabuko be-JIT, abenza imiyalo yomshini endizeni, umhlanganisi we-JIT ohlongozwayo kuRuby uqale abhale ikhodi ye-C kudiski, bese ebiza umhlanganisi wangaphandle we-C ukuthi akhiqize imiyalo yomshini (i-GCC isekelwa, iClang neMicrosoft VC ++).

Ukuze unike amandla i-JIT, kufanele ucacise inketho "-jit" lapho uqala i-ruby noma usethe le nketho kokuguquguqukayo kwemvelo kwe-RUBYOPT.

Uma kuqhathaniswa noRuby 2.5, ukufakwa kwezilinganiso ze-JIT izikhathi eziyi-1.7 ukusebenza kwezicelo ezinamandla ze-CPU.

Ngasikhathi sinye, intuthuko isalokhu iyisilingo futhi ayiyifanele kahle imithwalo ehambisana nomsebenzi omkhulu wokukhumbula.

Okunye ukuthuthuka okutholwe kule nguqulo kube yi I-RubyVM :: module yokuhlola ye-AbstractSyntaxTree, enikeza indlela yokuhlaziya ecubungula izintambo ezidlulisiwe njengekhodi yeRuby bese ibuyisa i-Abstract Syntax Tree (AST) yale khodi.

I-alias "#then" manje ingasetshenziselwa ukufinyelela indlela ye- "Kernel # yield_self". Okwezindlela ze- "Array # |" kanye ne- "Array # -" iphakamise iziteketiso ezingafundeka kakhudlwana "I-Array # union" ne- "Array # Difference".

Amagama ajwayelekile manje angaqala ngezinhlamvu ezinkulu ngaphandle kwe-ASCII.

Ukusekelwa kwahlinzekelwa futhi ngeNqwaba Yesikhashana, i-theap eyenzelwe izinto ezinesikhathi esifushane sokuphila kusetshenziswa amakilasi athile (Array, Hash, Object, Struct).

Isibonelo, ngenxa ye-theap, ukudala ama-hashes amancane, aphile isikhathi esifushane manje sekuphindwe kabili. Ukuhlolwa kwe-rdoc kukhombise ukwanda kwesivuno sika-6-7%.

Ukukhulisa ukusebenza kokushintshwa komongo, kuphakanyiswa ukusetshenziswa kwendabuko kwama-coroutine kwe-arm32, arm64, ppc64le, win32, win64, x86, ne-amd64 izakhiwo. I- "Fiber.yield" ne- "Fiber # resume" kumasistimu angama-64-bit Linux manje asebenza cishe cishe ka-5 ngokushesha.

Ngokuvamile, izinhlelo ezinamandla zibonisa ukwanda kokusebenza kuka-5%.

Ukuthuthuka okukhulu kuRuby 2.6.0

Uhlobo olusha lweRubyGems 3.0.1 selutholakele, lapho ukusekelwa kwezinketho ze- "–ri" ne "–rdoc" kuyekiwe, esikhundleni salokho okufanele usebenzise khona "- idokhumende" ne "–no-document".

IBundler manje isifakwe ngokuzenzakalela ukuphatha ukuncika kwamagugu.

Kungezwe ukusekelwa kwamabanga angaqediwe, isibonelo, "ary [1 ..]" noma "(1 ..). I- {…} »ngayinye.

Kokunye ukuthuthuka okungagqanyiswa, ungathola:

• Inketho ehlukile ingeziwe kundlela yohlelo lweKernel # ukuphakamisa okuhlukile ngephutha esikhundleni sokubuyisa okungamanga.
• Imodi ye-oneshot ibilokhu ikhona ingezwe kwimodyuli yokumboza, ebheka ukuthi umugqa ngamunye wenza okungenani kanye.
• Isigaba se-Enumerator :: Chain nezindlela ze- "Enumerable # chain" kanye ne- "Enumerator # +" ezifakiwe kuyo ziyangezwa ukudala amaketanga wamanani abaliwe.
• Ukusekelwa kwabasebenza «<<» no «>>» kungeziwe kumamojula we-Proc and Method, ngokwesibonelo, ukwakhiwa «(f << g) .call (3)» kuyefana ne- «f (g (3) )) ".

Ungayifaka kanjani iRuby 2.6.0 kuLinux?
