Goal

The goal is to:

• Scan the repo directory for .mqh files and check for any syntax errors.
• If syntax error is present in one of the files, build should fail (e.g. for fail1.mqh or fail2.mqh).
• The CI should display the compilation errors to the output (if any).

Details

• File to fix: appveyor.yml
  The file have two possibilities: /compile:. (whole folder) or forfiles approach, choose one).
• Current test result: /project/kenorb/ci-test/build/1.0.11 (always succeeds, which is wrong).
• To test, you can clone the repo (or create a new one), then setup Appveyor CI testing on your repo.
• The CI test needs to use the Metaeditor compiler to test the syntax (either 32bit or 64bit).

Resources

• You can install compiler from the site or download the binary (32bit or 64bit) to test on local.
• See: Compiling at MetaEditor Help
• Problem 1: Compiler may not return exit code 1 on error, it may return number of compiled files instead (AFAIK).
• Problem 2: Using foreach returns success as a whole, see: How to fail CI script in case of command error when using forfiles?
• Problem 3: Compiler outputs the errors under Wine, but not on Windows.
