REPL, Online IDE and Tools for Static Code Analysis

The code in general programming languages like Java and C++ and code is usually compiled and tested in IDEs. In other scripting languages, it's common to see a REPL (read-eval-print loop) language shell -- interactive interpreter.

REPL environment allows us to run the code piece by piece. This is very handy for testing purpose sometimes. Now there are some solutions in Java and C++.
[My thinking of picking a pair of similar tools comes from Hotelling's law -- "Linear City Model", though many more other tools are available, too.]

1. cint and igcc are two REPL simulators for C/C++.
2. javarepl and Eclipse's "scrap book" are two REPL simulators for Java.
3. ideone, codechef, and coding-ground provide online compiler suites for various programming languages(C++, Java, Scala, R, Python) by using cloud computing technologies.
4. cppcheck and are two tools for C++ static code analysis.

Coding ground is my favorite. It supports almost all popular languages, and claims 100% cloud. Best of all, it displays the command line and allows me to change the compiling options!

* As of December 2015, coding ground works well on my PC. It has an Android app for Tutorialspoint, but it's slow and Coding Ground on my Galaxy Note 4 is not working as well as it is on PCs.


  1. I read many blogs on static code analysis and in every blog I found that every developer fight against lot of false positives. Sometime it distract developer due to this distraction developer ignore important warnings. Still static code analysis tool help developers and plays vital role in programming.

  2. Hello Admin,

    The code as a rule programming dialects like Java and C++ and code is normally gathered and tried in IDEs. In other scripting dialects, it's entirely expected to see a REPL (read-eval-print circle) language shell - intelligent translator.
