module SlimLint::Utils
Miscellaneus collection of helper functions.
Public Instance Methods
Returns whether a glob pattern (or any of a list of patterns) matches the specified file.
This is defined here so our file globbing options are consistent everywhere we perform globbing.
@param glob [String, Array] @param file [String] @return [Boolean]
# File lib/slim_lint/utils.rb, line 17 def any_glob_matches?(globs_or_glob, file) path = File.expand_path(file) Array(globs_or_glob).any? do |glob| ::File.fnmatch?(File.expand_path(glob), path, ::File::FNM_PATHNAME | # Wildcards don't match path separators ::File::FNM_DOTMATCH) # `*` wildcard matches dotfiles end end
Count the number of consecutive items satisfying the given {Proc}.
@param items [Array] @param offset [Fixnum] index to start searching from @yield [item] Passes item to the provided block. @yieldparam item [Object] Item to evaluate as matching criteria for
inclusion
@yieldreturn [Boolean] whether to include the item @return [Integer]
# File lib/slim_lint/utils.rb, line 63 def count_consecutive(items, offset = 0) count = 1 count += 1 while (offset + count < items.count) && yield(items[offset + count]) count end
Find all consecutive items satisfying the given block of a minimum size, yielding each group of consecutive items to the provided block.
@param items [Array] @param satisfies [Proc] function that takes an item and returns true/false @param min_consecutive [Fixnum] minimum number of consecutive items before
yielding the group
@yield Passes list of consecutive items all matching the criteria defined
by the `satisfies` {Proc} to the provided block
@yieldparam group [Array] List of consecutive items @yieldreturn [Boolean] block should return whether item matches criteria
for inclusion
# File lib/slim_lint/utils.rb, line 38 def for_consecutive_items(items, satisfies, min_consecutive = 2) current_index = -1 while (current_index += 1) < items.count next unless satisfies[items[current_index]] count = count_consecutive(items, current_index, &satisfies) next unless count >= min_consecutive # Yield the chunk of consecutive items yield items[current_index...(current_index + count)] current_index += count # Skip this patch of consecutive items to find more end end
Calls a block of code with a modified set of environment variables, restoring them once the code has executed.
@param env [Hash] environment variables to set
# File lib/slim_lint/utils.rb, line 73 def with_environment(env) old_env = {} env.each do |var, value| old_env[var] = ENV[var.to_s] ENV[var.to_s] = value end yield ensure old_env.each { |var, value| ENV[var.to_s] = value } end
