• Regex to match anything (including the empty string) except a specific given string.

  - by dreeves

  I'd like to test whether a string contains "Kansas" followed by anything other than " State". Examples: "I am from Kansas" true "Kansas State is great" false "Kansas is a state" true "Kansas Kansas State" true "KansasState" true (For my immediate purposes this should work with mysql's REGEXP but if there's a more elegant way using PCRE, I'd like to see that too.)

  I have a string representing bits, such as: "0000101000010000" I want to convert it to get an array of bytes such as: {0x0A, 0x10} The number of bytes is variable but there will always be padding to form 8 bits per byte (so 1010 becomes 000010101).

  Not sure whats going on here, or what could be the integer in this case. Here's the code: def build_array_from_file(filename) contents = [] File.read(File.expand_path('lib/project_euler/' + filename), 'r') do |file| while line = file.get contents << line end end contents end filename is a string and I've checked to make sure the path comes up valid. Any thoughts? Thanks.

• How to check if a string has earlier been set using iabbr (full match)

  - by Sumit

  I am trying to check if a lhs is already abbreviated in vim. mapcheck, however, seems to have a problem. For example, iabbr swt switch echo mapcheck('sw','i',1) returns "switch" even when "switch" defined for "swt". mapargs seem to return a string even if there is a partial match with the lhs. Is there a way to find if an abbreviation has been defined for the "exact" match, i.e., the above mapcheck returning a "" instead.
