Count the number of non-blank SLOC in an Elixir project

gistfile1.sh

git ls-files | egrep '\.erl|\.ex[s]$' | xargs cat | sed '/^$/d' | wc -l

As of https://github.com/elixir-lang/elixir/tree/0df09a97488ceafe4133b024a79dca62c63a0165 I get 6529 lines of code. Pretty neat!

Compare that to Clojure's 72169.

A year later, it shows 15657 lines for code for Elixir.

Shouldn't it be

git ls-files | egrep '\.erl|\.exs?$' | xargs cat | sed '/^$/d' | wc -l

The original only matched .exs files for me.

Same command shows 34229 lines of code for Elixir as of elixir-lang/elixir@3f9ea58

The sed command can be changed to sed '/^$\|^\s*#/d' to ignore comment only lines

@minhajuddin for some reason I get more lines with your regex ; I've also tried this one sed '/(?:^$)|(?:^\s*#)/d' which yields the same results as yours.

by piping twice, though, I get the comment lines removed, as in:
git ls-files | egrep '\.erl|\.exs?$' | xargs cat | sed '/^$/d' | sed '/^\s*#/d' | wc -l

Same command show following line counts for different Elixir releases:

• v1.13.4 174794
• v1.12.3 165455
• v1.11.4 160327
• v1.10.4 152321
• v1.9.4 143453
• v1.8.2 136553
• v1.7.4 131250
• v1.6.6 125171
• v1.5.3 105227
• v1.4.5 96795
• v1.3.4 89698
• v1.2.6 80185
• v1.1.1 76340
• v1.0.5 69211
• v0.9.3 42682
• v0.8.3 38633
• v0.7.2 31105
• v0.6.0 25127
• v0.5.0 16887

Command that worked for me on MacOS to count all LoC (including ex and exs files), ignoring blank lines and comments:

git ls-files | egrep '\.erl|\.exs?$' | xargs cat | sed '/^\s*$/d' | sed '/^\s*#/d' | less
