I'm fairly new to Haskell, so apologies in advance if this is a stupid question.
I'm looking for a library that can parse command line flags, but in cases where the flags aren't provided on the command line, can also obtain values from environment variables. I've tried some Google and Hackage searches, but couldn't find anything like that. Does such a library exist, or is there some other best-practice for handling such things?

Take a look at System.Environment module in Base package. Specifically getArgs and getEnv.

I had never seen any ".arxml" file provided (as a example) whith Autosar documentetion specification on the www.autosar.org.
Keep on mind that there is three type of .arxml file for AUTOSAR (for the Vector software stack) - *bswmd, *ecuc and *swc file.
Here is a simple example of MyECU.ecuc.arxml file. Hope this will help you in some way:

I'm looking for something similar to Python's os.path.expandvars in Haskell, i.e., a FilePath -> IO FilePath function that is
Cross-platform (supports both Windows %VAR% and Unix $VAR styles)
Standard (I don't want to write my own function for that).
Example:
> expandVars "$HOME/foo/bar"
"/home/someuser/foo/bar"
I've searched on Hoogle, Hayoo and Google but found nothing, which is surprising given the number of cross-platform Haskell tools. The closest I found is this Unix-only implementation. Perhaps there is some project which implements this as a subroutine?

I was only able to find this one (https://github.com/rollxx/vim-antlr), but it was made for version 3. Does anyone knows where I can find proper syntax for version 4?
There's another fork of rollx/vim-antlr that supports ANTLR4: dylon/vim-antlr
The fork that pascal mentioned is now unavailable, but I found another working one in GitHub’s list of forks of rollxx/vim-antlr. That fork is jrozner/vim-antlr.
There is a fork that supports version 4: blinks/vim-antlr

I want know where comprehensive list of APIs of watir-webdriver related to browser, elements is located. I am looking something like: http://release.seleniumhq.org/selenium-remote-control/0.9.0/doc/java/
Here it is: http://rubydoc.info/gems/watir-webdriver/frames
In addition to the Rdoc that Zelkjo linked, your other best way to understand how stuff works (aside from the tutorials and the wiki etc) would be to review the tests in watirspec, since they basically document how everything is expected to work. https://github.com/watir/watirspec
API Documentation:
For watir-webdriver
For watir-classic

I can also settle for a web-based interface, but a good command-line tool is preferable. Now, I have tried to use xsd.exe that comes with mono-devel, but that skipped a whole bunch of stuff that was mentioned in the xml file.
I understand that I will need to hand-tweak the output, but I do want something decent to start with.
Try the tool that comes with the spring framework:
