• Java - get index of key in HashMap?

  - by llm

  In java if I am looping over the keySet() of a HashMap, how do I (inside the loop), get the numerical index of that key? Basically, as I loop through the map, I want to be able to get 0,1,2...I figure this would be cleaner than declaring an int and incrementing with each iteration. Thanks.

• Detect if a key is bound to something in vim

  - by WishCow

  I'd like to know if there is a way to figure out if a key does something in vim. I know that I can use :map to see user-defined mappings, but is there something for the built-in stuff? For example, I always had CTRL-W bound to close tab, because I thought that it was unused. After half a year, I found out that there are some sequences that use it, like CTRL-W CTRL-S to split the window, and it was a nightmare to retrain myself.

• Python: if key in dict vs. try/except

  - by LeeMobile

  I have a question about idioms and readability, and there seems to be a clash of Python philosophies for this particular case: I want to build dictionary A from dictionary B. If a specific key does not exist in B, then do nothing and continue on. Which way is better? try: A["blah"] = B["blah"] except KeyError: pass or if "blah" in B: A["blah"] = B["blah"] "Do and ask for forgiveness" vs. "simplicity and explicitness". Which is better and why?

• bind key to complete filename wherever the context is in Zsh

  - by lilydjwg

  Sometimes I want a filename instead of what zsh guesses for me. For example, I have a PNG file without a proper .png suffix, which makes zsh think it isn't a picture and won't list it when I type Tab to complete arguments of display. I am wondering if there is a key sequence that completes for a filename wherever the context is, like ^XC for _correct_filename, or how to configure zsh to do the thing?

  I am trying to read the 32-bit HKLM\SOFTWARE registry key from a 64-bit (C#) application. This, of course, keeps redirecting my view to HKLM\SOFTWARE\Wow6432Node. According to what I've found this is doable, but I can't seem to find a .NET example anywhere. I just need to read; not write. Anyone ran across this before?
