. The result should be that a map gets appended to the vector. Let’s get ourselves part of the way there. Create the file journal and make it executable with chmod +x journal, then make it look like this: #!/usr/bin/env bb (require '[babashka.fs :as fs]) (require '[clojure....
If any text precedes an opening bracket((,{and[) or follows a closing bracket(),}and]), separate that text from that bracket with a space. Conversely, leave no space after an opening bracket and before following text, or after preceding text and before a closing bracket. ;; good(foo(b...
returnfilelist在函数内部使用def。def在包的全局名称空间中定义和绑定符号，这几乎不是您想要做的事情。
A Clojure map is a collection of key/value pairs. Maps have a literal form surrounded by curly braces. You can use a map literal to create a lookup table for the inventors of programming languages: (def inventors {"Lisp" "McCarthy" "Clojure" "Hickey"}) Maps are function If you pass ...

Clojure code usesprefix notation(also calledpolish notation) to represent function calls. 其实很多人会对于这个很不习惯, 主要是因为数学计算操作符, 比如(+ 1 2) 其实对于函数, prefix是一种常态, 换个写法 add(1, 2), 是不是就比较容易接受了 ...
