Ulimi lohlelo lwe-LISP lungolunye lwakudala kakhulu futhi, ngesikhathi esifanayo, olunye oluthakazelisa kakhulu emhlabeni wekhompyutha. Naphezu kokuphila kwayo isikhathi eside, i-LISP isalokhu isebenza futhi inamandla endaweni yanamuhla yobuchwepheshe. Kulesi sihloko, sizobheka kabanzi ngendawo ye-LISP, sihlole izici zayo ezihlukile, izinhlelo zokusebenza zesimanjemanje, nokuthi kungani ihlala iyinketho ekhangayo kubahleli bohlelo bawo wonke amazinga anentshisekelo yokuhlela. ukuhlukaniswa kwezilimi zokuhlela.
Ulimi lohlelo lwe-LISP: Ukubheka ingqikithi yalo
Ulimi lohlelo lwe-LISP, oluqanjwe ngokuthi "UHLU Lokucubungula," lwadalwa ngu-John McCarthy ngo-1958. Kusukela lapho, luye lwavela futhi lwahlanganiswa lwaba yizilimi zesigodi eziningi, kuyilapho lugcina ifilosofi yalo eyinhloko yokuphatha ikhodi njengedatha nedatha njengekhodi.
I-LISP ibonakala nge-syntax esekelwe kubakaki kanye nokugxila kwayo ezinhlelweni ezisebenzayo. Kodwa yini eyenza lolu limi lukhetheke kangaka? Ake sibheke ezinye zezici zayo eziphawuleka kakhulu:
- I-HomoiconicityKu-LISP, ikhodi kanye nedatha kuvezwa ngendlela efanayo, okusiza i-metaprogramming.
- Ukuqoqwa kukadoti: I-LISP isungule ukuqaliswa kokuqoqwa kukadoti okuzenzakalelayo.
- Izici zesigaba sokuqala: Imisebenzi ingadluliswa njengama-agumenti, ibuyiswe njengamavelu, futhi yabelwe okuguquguqukayo.
- amamakhro: I-LISP inikeza uhlelo olukhulu olunamandla kakhulu oluvumela ukuthi ulimi lunwetshwe.
Lezi zici zenza i-LISP iguquguquke ngendlela emangalisayo futhi ibe namandla, okuvumela abahleli bezinhlelo ukuthi baveze imibono eyinkimbinkimbi kafushane nangobuhle.
Umlando nokuziphendukela kwe-LISP
Umlando we-LISP, uqalwe ngu John McCarthy, iyathakazelisa futhi igcwele izinto ezintsha ezibe nomthelela ekuthuthukisweni kwezinye izilimi zokuhlela. Kusukela ekuqanjweni kwayo kumalebhu e-MIT kuya ekusetshenzisweni kwayo ezinhlelweni zobuhlakani bokwenziwa, i-LISP isihambe indlela ende.
Ezinsukwini zayo zakuqala, i-LISP yayisetshenziswa ngokuyinhloko ocwaningweni lobuhlakani bokwenziwa. Ngokuhamba kwesikhathi, izilimi zesigodi ezihlukene zathuthuka, njenge-Common Lisp kanye ne-Scheme, ngayinye inezici zayo kanye nemiphakathi yabasebenzisi.
Esinye sezigigaba ezibalulekile emlandweni we-LISP kwaba ukudalwa kwe-Emacs, umhleli wombhalo onwebekayo futhi owenzeka ngendlela oyifisayo osebenzisa i-Emacs Lisp njengolimi lwayo olunwetshiwe. Lesi isibonelo esisodwa sokuthi i-LISP ishiye kanjani uphawu kumathuluzi asetshenziswa abahleli nsuku zonke.
Izici ezihlukile ze-LISP
Uhlelo olusebenzayo ku-LISP
I-LISP yaziwa ngokugcizelela kwayo kakhulu ukuhlela okusebenzayo. Le paradigm iphatha ukubala njengokuhlola imisebenzi yezibalo futhi igwema izinguquko zesimo kanye nedatha eguquguqukayo. Ku-LISP, imisebenzi izakhamuzi zesigaba sokuqala, okusho ukuthi ingadluliswa njengezimpikiswano, ibuyiselwe njengamavelu, futhi yabelwe okuguquguqukayo.
Ake sibheke isibonelo esilula somsebenzi we-LISP obala i-factorial yenombolo:
(i-defun factorial (n)
(uma (<= n 1)
1
(* n (i-factorial (- n 1)))))
Le khodi ikhombisa ubuhle nobufushane obunikezwa yi-LISP. I-Recursion, umqondo oyisisekelo ohlelweni olusebenzayo, isetshenziswa ngendlela engokwemvelo nefundekayo.
Ukushintsha izinhlu nezakhiwo zedatha
Njengoba igama layo liphakamisa, i-LISP ihamba phambili ezinhlwini zokucubungula. Uhlu oluku-LISP luyizakhiwo zedatha eziyisisekelo neziguquguqukayo ezingamela cishe noma yiluphi uhlobo lolwazi.
Isibonelo, nansi indlela esingaluchaza futhi silusebenzise ngayo uhlu ku-LISP:
(setq uhlu lwami '(1 2 3 4 5))
(char my-list); Ibuyisela ingxenye yokuqala: 1
(cdr my-list); Ibuyisela uhlu olusele: (2 3 4 5)
(ububi 0 uhlu lwami); Engeza into ekuqaleni: (0 1 2 3 4 5)
Leli khono lokukhohlisa izinhlu ngempumelelo nangobuhle kungesinye sezizathu ezenza i-LISP ihlale idumile emikhakheni efana nobuhlakani bokwenziwa kanye nokucutshungulwa kolimi lwemvelo.
I-syntax ye-LISP nesakhiwo esiyisisekelo
I-syntax ye-LISP ilula ngokumangalisayo futhi ayiguquki. Yonke into eku-LISP ivezwa njengohlu kubakaki, lapho isici sokuqala ngokuvamile siwumsebenzi noma isisebenzisi, futhi izici ezilandelayo ziyizimpikiswano.
Isibonelo, isisho esilula ku-LISP singase sibukeke kanje:
(+ 2 3 4)
Le nkulumo yengeza izinombolo 2, 3, kanye no-4. Ukuba lula kwale syntax kwenza i-LISP ibe lula ukuyihlaziya kuyo yomibili imishini nakubantu, uma usuyijwayele.
Kodwa ingabe ayidida nabakaki abaningi kangaka? Eqinisweni, abahleli bezinhlelo be-LISP abanolwazi bathola ukuthi lokhu kuvumelana kwe-syntactic kuyinzuzo. Ngaphezu kwalokho, izindawo zokuthuthukiswa kwe-LISP zesimanje zihlinzeka ngamathuluzi okuphatha nokubonisa abakaki ngempumelelo.
Izicelo ezisebenzayo ze-LISP namuhla
Naphezu kweminyaka yayo, i-LISP isasebenza emikhakheni eminingana yekhompyutha yesimanje. Ezinye zezinhlelo zokusebenza zayo eziphawuleka kakhulu zifaka:
- I-Artificial Intelligence kanye Nokufunda Ngomshini: I-LISP isetshenziswa ezinhlelweni zochwepheshe kanye nocwaningo lwe-AI ngenxa yekhono layo lokuphatha izimpawu nokucabanga okungacacile.
- Ukucubungula Ulimi LwemveloIkhono le-LISP lokukhohlisa izakhiwo zedatha eziyinkimbinkimbi liyenza ilungele imisebenzi ye-NLP.
- Ukuthuthukiswa Kwegeyimu: Ezinye izinjini zegeyimu, njengaleyo esetshenziswa i-Naughty Dog ezihlokweni ezinjengokuthi "Jak and Daxter", sebenzisa izilimi zesigodi ze-LISP.
- izimali: I-LISP isetshenziswa kwezinye izinhlelo zokuhweba ze-algorithmic ngenxa yekhono layo lokwenza izibalo eziyinkimbinkimbi ngokushesha.
- Umculo nobuciko bokukhiqiza: Ukuvumelana nezimo kwe-LISP kuyenza idume kumaphrojekthi wokukhiqiza nomculo.
Lezi zinhlelo zokusebenza zibonisa ukuguquguquka namandla e-LISP emikhakheni eyahlukene, kusukela kubuchwepheshe obuphezulu kuya kwezobuciko bokudala.
Izinzuzo kanye nebubi bokusebenzisa i-LISP
Njenganoma yiluphi ulimi lokuhlela, i-LISP inobuhle nebubi bayo. Ake sibheke ezinye zazo:
Ventajas:
- Ukuguquguquka okukhulu nokunwebeka
- Isistimu ye-macro enamandla
- Kuhle kakhulu ku-prototyping esheshayo

Amathuluzi nezindawo zokuthuthukisa ze-LISP
Ukuze usebenze ne-LISP ngempumelelo, kubalulekile ukuba namathuluzi afanele. Ngenhlanhla, kunezindawo ezimbalwa zokuthuthukisa ezididiyelwe (ama-IDE) namathuluzi enza ukuhlela ku-LISP kube lula:
- Emacs: Nakuba ingaphezu nje kwe-IDE, i-Emacs idume kakhulu phakathi kwabahleli bezinhlelo be-LISP ngenxa yokuhlanganiswa kwayo okujulile nolimi.
- I-LispWorks: I-IDE yezentengiso ehlinzeka ngendawo yokuthuthukisa ephelele ye-Common Lisp.
- I-SLIME: I-Superior Lisp Interaction Mode ye-Emacs, isandiso esishintsha ama-Emacs abe yi-LISP IDE enamandla.
- Irakhethi: Indawo yokuthuthukisa ehlanganisa nolimi lwayo lwe-LISP, elungele abasaqalayo nabafundisi.
- I-Portacle: Ukusabalalisa kwe-Common Lisp okuphathekayo okuhlanganisa i-Emacs, i-SBCL, i-Quicklisp, ne-SLIME, konke kulungiselelwe kusengaphambili futhi kulungele ukusetshenziswa.
Lawa mathuluzi awenzi nje ukubhala ikhodi ye-LISP kube lula, kodwa futhi ahlinzeka ngezilungisi zamaphutha, amaphrofayili, nezinye izinsiza ezibalulekile ekuthuthukisweni kochwepheshe.
Umphakathi kanye nezinsiza zokufunda i-LISP
Naphezu kokungabi mikhulu njengemiphakathi yezilimi ezivamile, umphakathi we-LISP uyasebenza futhi uyamukela. Kunezinsiza eziningi ezitholakalayo zalabo abafisa ukufunda noma ukuthuthukisa amakhono abo e-LISP:
- Amabhuku: Ingoma ka-Peter Seibel ethi "Practical Common Lisp" nekaConrad Barski ethi "Land of Lisp" zingamaphuzu amahle kakhulu okuqala.
- izinkundla inthanethi: r/lisp ku-Reddit kanye ne inkundla ye-com.lang.lisp izindawo ezisebenzayo zezingxoxo mayelana ne-LISP.
- izifundo ze-inthanethi: Amapulatifomu afana ne-Coursera ne-edX ngezikhathi ezithile anikela ngezifundo ezihlobene ne-LISP.
