Pandoc da abubuwan da ba a sani ba

Lokaci na ƙarshe da na ambata Haskell yana cikin labarin game da XMonad. Koyaya, ba shine kawai abin ban mamaki a duniya da na gabatar muku ba.

Tabbas kowa ya riga ya sani Yankewa, kuma idan ban gabatar dasu ba. Harshe ne na alamar haske wanda ke bamu damar zama cikin sauri da inganci yayin rubuta rubutu. Ya isa yanzu.

To, Markdown ba shi kaɗai bane kuma akwai yaruka da yawa daga can don aiwatar da wannan aikin. A yadda aka saba kowa yana zuwa da ra'ayin ɗaukar rubutu a sarari tare da wasu alamomi da wuce shi don samar da shi azaman HTML, LaTex da sauransu. Duk da kyau har zuwa can.

Wannan ya kawo matsaloli da yawa. Na farko, kuma mafi mahimmanci, shine cewa wasu aiwatarwar basu da todas siffofin da muke so. Ko kuma harshen tallatawa wanda ya riga ya aiwatar da wannan ba ma so.

Kuma kafin mu tsunduma cikin son rai, yakamata kuyi tunani ku gane cewa akwai mafita mafi kyawu. Wani abu da ke juya kowane yare alama zuwa wani abu dabam. Kowa.

Anan ne Haskell ya shigo cikin hoto. Abun al'ajabi da nake magana akansa ya wanzu, yana raye, yana da suna, yana aiki kuma yana da ban mamaki. Kira da kanta Pandoc kuma ta fito ne daga hannun wani masanin falsafa a Jami'ar Berkeley, John MacFarlane. Riƙe, saboda kyau yana farawa.

Duk da duka

Zamu iya tsammanin pandoc ya bayar da mediocre ɗaukar hoto game da komai, ta hanyar rashin mai da hankali. Amma ba. An yi kyakkyawan aiki kuma yana da ayyuka masu ban mamaki.

Don sanya shi a sauƙaƙe, zaku wuce kowane fayil na tushe zuwa pandoc (ko dai a cikin Markdown ko a sake sake fasalta rubutu ko wasu da pandoc ke tallafawa) kuma ya canza shi zuwa tsarin da aka gama, kamar -ko kowa ya shirya? -
