*turbo-linecount* is a tool that simply counts the number of lines in a file, as fast as possible. It reads the file in large chunks into several threads and quickly scans the file for line endings.
Many times, you have to count the number of lines in text file on disk. The typical solution is to use `wc -l` on the command line. `wc -l` uses buffered streams to process the file, which has its advantages, but it is slower than direct memory mapped file access. You can't 'pipe' to *turbo-linecount* however. This may change in a future release.
To build *turbo-linecount*, we use *cmake*. Cmake 3.0.0 or higher is the preferred version as of this release. For simplified building on Windows, a Visual Studio 2013 solution file is also included.
This will build and install the command line utility `tlc`, a shared library `libturbo_linecount`, a static library `libturbo_linecount_static`, and a header file `turbo_linecount.h`.
Testing cmake against `wc -l` and `python` can be done with the test scripts. To generate some random test files, run `create_testfiles.sh`, and four test files, one 10MB, one 100MB, one 1GB, and one 10GB file will be created. Feel free to delete these when you're done testing to save space.
Performance on Windows and Mac OS X is excellent for all file sizes. Performance on Linux and other operating systems is good, but can be better. Stay tuned.
