flycheck-d-unittest's Introduction

Flycheck-d-unittest

This library adds D unittest support to flycheck.

Requirements:

DMD 2.066 or later
Flycheck
dash.el

You can install it by using package-install via MELPA.

To use this package, add the following line to your .emacs file:

    (require 'flycheck-d-unittest)
    (setup-flycheck-d-unittest)

It detects any compile errors, warnings and deprecated features during unittest.

Note: Flycheck-d-unittest runs DMD with -unittest and -main option for unittesting. Please enclose main function in version(!unittest) block as follows:

import std.stdio;

version(unittest) {}
else
void main()
{
    writeln("Hello!");
}

unittest
{
    assert(1+2 == 3);
}

flycheck-d-unittest's Issues

Unnecessary error for buffers containing a main function

Flags sent to dmd should not contain -main flag if the current buffer contains a D main function.

This will inhibit the unneccessary error message:

3539     error    only one main allowed, -main switch added another main() (d-dmd-unittest)

This is preferrably solved by searching for a regexp matching a D main function definition such as

void main(string args[])

int the current buffer.

Here's a somewhat relaxed Emacs-Lisp regexp that works for me

(defcustom d-main-function-regexp "^\\(?:void\\|int\\)?[[:space:]]*main[[:space:]]*([[:space:]]*string[[:space:]]+"
  "Regexp matching C-style main function.")

Flycheck-d-unittest uses `s-prepend` without requirement of s.el

It should be fixed.

Flycheck moved

Hello,

just wanted to drop you a note, that I moved Flycheck into it's own organization. It's now at https://github.com/flycheck/flycheck. You may want to update your bookmarks, and all the links in this extension.
