Just another blazingly fast LOC counter.

It works (and it's really fast too) but it is not finished yet.

You may check the [known issues below](#known-issues) to make sure that you want to use it.



### Disclaimer



This is my first ever project in Rust; developed while reading the Rust Book!

My sincere apologies to the Rust community for possibly abusing the language; at the time `rlocc` is written I've been still fighting with the borrow checker :P

## Build 



Assuming Rust is already installed, `rlocc` can be built using the provided Makefile:



```text

$ make

```



which simply uses cargo as usual:



```text

$ RUSTFLAGS="-Ctarget-cpu=native" cargo build --release

```



## Usage 



Even though `rlocc` has been developed as a library, for now it is mostly meant to be used through the accompanying binary.

In other words, its API is not really well-thought for use outside the provided binary.



As a command line tool, `rlocc` is very simple to use: it receives any number of file or directory names as command line input, and walks through them counting them.



For example, to count files `file1`, `../file3` and all files under `~/dir2`, one can issue:



```text

$ rlocc file1 ~/dir2 ../file3

```



No command line flags are supported at this time.



## Platforms 



So far `rlocc` has only been tested on `linux/amd64` with Rust `1.42.0` or later.



## Supported File Types 



Currently `rlocc` supports 76 types of files.

It guesses the file type mostly via file name extensions, with very few exceptions (for Makefile, Dockerfile, etc).

- Ada

- Assembly

- Autoconf

- AWK

- Batch

- C

## Known issues & TODOs 



- *TODO:* Proper code & installation documentation to publish at crates.io.



- *TODO:* Command line options for the binary.



- *TODO:* For now, when a token that begins a multi-line comment appears inside a string (in any supported language that supports both multi-line comments and strings) , `rlocc` cannot handle it and the results of LOC count for that whole file get calculated wrong with high probability.



- Nested comments are not handled. (I don't think I'm gonna fix this, since it's not really a use case for me.)
