locc is incredibly lightweight when compared to loc / scc / etc (orders of magnitude smaller), and generally runs faster than them as well, albeit with the least amount of stats / customisation.
Stats on a 12 thread CPU with 32GB RAM, run on the Linux repo:
| Program | Size | Execution Time |
----------------------------------------------
| loc | 4786KiB | 758.000ms (+/-19.7ms) |
| scc | 4561KiB | 1135.667ms (+/-6.7ms) |
| locc | 298KiB | 724.136ms (+/-4.7ms) |
locc supports a few command line parameters:
--skip-substr=<substr0>[,substr1,...]: Add path substring pattern to ignore-e=/--extensions=<.ext0>[,.ext1,...]: Additional extensions to count in implicit mode--sort-by=<column_name>: Sort results by column (lowercase,codeby default)-o/--one-thread: Run everything on the main thread-b/--blanks: Include blank lines as lines of code-q/--quiet: Print nothing but total lines of code--verbose: Lots of output-d/--debug: Misc debug output-h/--help: Print help--version: Print version
Use CMake and a generator of your choice. Requirements:
- Windows / Linux (any architecture)
- C++20 compiler (and stdlib)
