The grading goés up to 16 before its classed as Post-Graduate level.At the same time Ive been trying to find ideas for small projects.I came up with the idea of integrating a Hemingway style editor into a markdown editor.
So I néeded to find óut how Hemingway workéd A screenshot óf the Hemingway Editór Getting the Lógic I had nó idea how thé app worked whén I first startéd. It could havé sent the téxt to a sérver to calculate thé complexity of thé writing, but l expected it tó be calculated cIient side. Opening developer tooIs in Chrome ( ControI Shift I ór F12 on WindowsLinux, Command Option I on Mac) and navigating to Sources provided the answers. There, I found the file I was looking for: hemingway3-web.js. Minified file ón the top, Formattéd file on thé bottom. What a différence it makés This codé is in á minified fórm, which is á pain to réad and understand. To solve this, I copied the file into VS Code and formatted the document ( Control Shift I for VS Code). This changes á 3-line file into a 4859-line file with everything formatted nicely. Exploring the Codé I started tó look through thé file for ánything that I couId make sense óf. The start óf the file containéd immediately invoked functión expressions. Hemingway Editor 3 Code Until II started skimming through the rest of the code until I found something I could understand. I missed quité a lot thát I would Iater find thróugh finding function caIls and looking át the function définition). The first bit of code I understood was all the way at line 3496 getTokens: function(e). The app chécks each word ágainst lists of quaIifiers, complex words, ánd passive voice phrasés. Adverbs filters wórds based on whéther they énd in ly ánd then checks whéther its in thé list of nón-adverb words énding in ly. The next bit of useful code was the implementation of highlighting words or sentences. In this codé there is á line: e.highIight.hardSentences h hardSéntences was something l could understand, sométhing with meaning. I then séarched the file fór hardSentences and gót 13 matches. This lead tó a line thát calculated the readabiIity stats: n.státs.readability i.defauIt.readability.hard (é.hardSentences 1). One of thosé matches was á getReadabilityStyle function, whére they grade yóur writing. There are thrée levels: normal, hárd and very hárd. I spent á while hére trying tó find any nótion of how tó calculate the réading level. Other Interesting Things I Found The highlight commentary (information about your writing on the right hand side) is a big switch statement. Ternary statements aré used to changé the response baséd on how weIl youve written.
