Clojure reduce: one case for text processing

As a practice, I managed to illustrate Clojure files using illustrate.clj, but my original idea was to annotate org-mode files of blogs. It's not uncommon that a blog post has some code snippets.

But it missed the feature until last night, as I wasn't sure how to implement it appropriately before and didn't have enough time.

For example, I may have an org-mode like this:

sum of two numbers:
#+begin_src clojure
(+ 1 2)
#+end_src

I want to have a result comment ((;; => 3)) after each top-level form after using illustrate.clj: sum of two numbers:

illustrate.clj to Illustrate Clojure Snippet

To get my hands dirty with Clojure, I am trying to find or implement Clojure's string functions in the sense of Python. Python has powerful string APIs, and I also want to see how powerful Clojure could be in this field. That would be interesting.

As shown in the cheatsheet, Clojure has implemented most of them, and there are some that I have to implement myself, like title-case.

Along the way, I found it was a little cumbersome to append the evaluation result and the result of calling them, for example,

I'm used to learning by practicing, so when I learned Clojure, I always kept an eye on chances to write code in it.

Scripting is an excellent field to practice, but the experience is not so good. On the one hand, it's too hacky to wrap Clojure code in a shell script with the shell bang. On the other hand, the startup time of JVM is too long to hurt the user experience.
