Uhlelo lokusetha kabusha \(\TeX\) lwakhiwa ngo-1977 nguDonald E. Knuth wodumo . Iphakheji yesoftware \(\LaTeX\) iseseyingxenye ye-repertoire ejwayelekile lapho kwenziwa amaphepha esayensi. Ngamathuluzi amabili alandelayo, ama-PDF asevele enziwe namanothi abhalwe ngesandla angaguqulwa ngokuzenzakalela abe yi-TeX. Imiphumela ithembisa kakhulu.
Ithuluzi lokuqala, iMathpix , njengamanje lijabulela ukuheha kwangempela ezinkundleni zokuxhumana. Igxile ekuguquleni amafomula ngamanye. Ingxenye yesikrini samanje ingagqanyiswa futhi iguqulwe ngenhlanganisela yokhiye. Lolu hlelo lunikeza izixazululo eziningana ngokuhlolwa kokunemba. Ngikuhlolile lokhu ngisebenzisa ifomula evela ku- Ethereum Yellow Paper:
$$n(\mathfrak{I}, i) \equiv \left\{\begin{array}{ll}{( )} & {\text { if } \quad \mathfrak{I}=\varnothing} \\ {c(\mathfrak{J}, i)} & {\text { if } \quad|c(\mathfrak{I}, i)|<32} \\ {\operatorname{KEC}(c(\mathfrak{I}, i))} & {\text { otherwise }}\end{array}\right.$$
Ithuluzi lesibili, i-InfinityReader, selikhona cishe iminyaka eyi-15. Lolu hlelo oluphelelwe yisikhathi lungaguqula wonke amadokhumenti (inguqulo yesivivinyo samahhala ikuvumela ukuthi uzame ikhasi elilodwa). Lungaphinde lwenziwe ngokuzenzakalelayo kusuka kulayini womyalo futhi luphatha amafomethi amaningi amafayela okufaka, okuhlanganisa nokukhipha i-MathML . Isibonelo esingenhla senza kabi kancane kulokhu.:
$$n(\mathrm{I},\ i)\equiv \left\{ \begin{array}{ll} () & \mathrm{i}\mathrm{f}\ \mathrm{I}=\emptyset\\ c(\mathrm{I},\ i) & \mathrm{i}\mathrm{f}\ \Vert c(\mathrm{I},\ i\ <32\\ \mathrm{K}\mathrm{E}\mathrm{C}(c(\mathrm{I},\ i)) & \mathrm{o}\mathrm{t}\mathrm{h}\mathrm{e}\mathrm{r}\mathrm{w}\mathrm{i}\mathrm{s}\mathrm{e} \end{array} \right.$$
Lawa mathuluzi enza kube lula ukuthayipha okudingekayo ukuze kuguqulwe amafomula namadokhumenti ngokushesha. Kodwa-ke, ukulungiswa ngesandla kusadingeka ezimweni eziningi. Siphetha ngengcaphuno evela kuDonald E. Knuth: “Indlela yami yokusebenza evamile ukubhala konke kuqala ngepensela nephepha, ngihlezi eceleni kwebhasikidi elikhulu likadoti. Bese ngisebenzisa i-Emacs ukufaka umbhalo emshinini wami.”
