# benchwarmer
# ===========
#
# A gem that provides a nice DSL for a common type of benchmark.
#
# Specifically:
require "rubygems"
require "benchwarmer"
TIMES = 100_000
Benchmark.warmer(TIMES) do # [1]
columns :one, :two, :three # [2]
titles :one => "Option 1", :three => "Option 3" # [3]
group("Squeezing") do # [4]
report "with #squeeze" do # [5]
one { "abc//def//ghi//jkl".squeeze("/") } # [6]
two { "abc///def///ghi///jkl".squeeze("/") }
three { "abc////def////ghi////jkl".squeeze("/") }
end
report "with #gsub" do
one { "abc//def//ghi//jkl".gsub(/\/+/, "/") }
two { "abc///def///ghi///jkl".gsub(/\/+/, "/") }
three { "abc////def////ghi////jkl".gsub(/\/+/, "/") }
end
end
group("Spliting") do
report "with #split" do
one { "aaa/aaa/aaa.bbb.ccc.ddd".split(".") }
two { "aaa//aaa//aaa.bbb.ccc.ddd.eee".split(".") }
three { "aaa///aaa///aaa.bbb.ccc.ddd.eee.fff".split(".") }
end
report "with #match" do
one { "aaa/aaa/aaa.bbb.ccc.ddd".match(/\.([^\.]*)$/) }
two { "aaa//aaa//aaa.bbb.ccc.ddd.eee".match(/\.([^\.]*)$/) }
three { "aaa///aaa///aaa.bbb.ccc.ddd.eee.fff".match(/\.([^\.]*)$/) }
end
end
end
# [1] Specify the number of times you want to run each benchmark
# [2] Specify the column names. By default, they will be displayed as upcased
# versions of themselves.
# [3] Specify prettier titles via a Hash. You do *not* need to specify the
# same column in both columns and titles.
# [4] Specify a group of benchmarks you wish to run
# [5] Specify the name of the report you wish to run
# [6] Optionally, specify several different variants of the benchmark. This could
# be useful if you're testing a new alorithm, and wish to compare a bunch of
# benchmarks against each algorithms. In most cases, you will probably want to
# use the variant below, which does not require columns.
# Output:
# Running the benchmarks 100000 times each...
#
# Option 1 | TWO | Option 3 |
# -----------------------------------------------------
# Squeezing with #squeeze 0.15 | 0.15 | 0.14 |
# with #gsub 0.38 | 0.35 | 0.36 |
# -----------------------------------------------------
# Spliting with #split 0.43 | 0.51 | 0.61 |
# with #match 0.29 | 0.35 | 0.38 |
# -----------------------------------------------------
