Ever wanted/needed to know how many lines are empty, comments, docstrings or actual code in some Python scripts of yours ?

Presenting **linestats: a small Python module to count the number of scripted, commented, docstringed, and empty lines in Python code**. Here is what it contains *and* what it does: [linestats.txt](https://github.com/fpavogt/linestats/blob/master/linestats.txt)

## Installation

linestats is available on pypi. The following command should take care of things:
```
pip install linestats
```

Alternatively, you can also get the code from its [dedicated Github repository](https://github.com/fpavogt/linestats).

## Running
Using linestats is fairly straightforward. You can do so (1) in any decent terminal using the in-built entry point, or (2) from within a Python shell by importing the corresponding module. Both methods are the same, and here's how they work:
  * from a terminal: The basic syntax is
     ```
     linestats -p some/path/to/dir/or/file.py
     ```
     This will process the `file.py` (or all `.py`file located at the indicated location, if a directory is specified). The other options are:
     - `-h` for help,
     - `-r` to run a recursive search for `.py` files in subfolders,
     - `-s output_file.txt` to save the statistics to file instead of `sys.stdout`,
     - `-v` to print the linestats version, and
     - `-w` to print also the name of the files that are being skipped.

  * from a Python script/shell:
     ```python3
     import linestats
     from pathlib import Path

     p = Path('some', 'path', 'to', 'dir', 'or', 'file.py')
     s = Path('.', 'output_file.py')

     linestats.extract_line_stats(p, recursive=True, save_to_file=s, verbose=False)
     ```

## Limitations
linestats is extremely basic, and the output should be largely self-explanatory. Still, here are a few aspects to keep in mind when using this code:
1. linestats will process `.py` files. At present, there is no way to force the processing of other file types.
2. The different lines are counted in the following category order: **docstrings -> comments -> emtpy -> code**.
  Each step feeds the following only with the lines that do not belong to it. This implies, for example, that
    * an empty line inside a docstring is counted as a docstring line,
    * a docstring line starting with `#` is also counted as a docstring line,
    * `a = 4 # A comment on the same line as code` would be counted as a code line, and
    * each line belongs to a single category, is counted once only, so the sum of all the categories adds up to 100%.
