将markdown编译为html
我们不难 YY 出如下巴克斯范式 article -> title article | line article | ε title -> POUND line line -> POUND是 若干# 字符. TEXT 是遇到换行符之前的文本. 所以要进行单子替换，于是得到我们最终的语法推导规则 article -> title_or_line article | ε title_or_line -> POUND line | 词法解析 本例中的token仅仅有 POUND、TEXT、LF 三个. 只需要提取文本中相应的字符串即可。 ] = LEX_TEXT, row1[CHARACTER_OTHER] = LEX_TEXT trans[LEX_POUND] = row1 let row2 = new Map() row2[CHARACTER_POUND
