dphogit / ccwc

Challenge to build own version of the Unix wc CLI tool.

ccwc

Coding challenge tool build our own version of the Unix wc command line tool. Read more about wc on the man page.

I wanted to do this simple challenge because I wanted to develop in C and try Neovim as my development environment (I'm liking it!).

Things I learned:

• Vim/Neovim environments (NvChad, Lua configs, plugins, LSP, keybindings etc.)
• C (File operations, streams, getopt, character functions, locales)
• C tooling (Make/Makefile, clangd, clang-format)

Build and Usage

Uses a Makefile to build into bin/ccwc. Simply run make to create the ccwc executable located in bin. Then run with:

bin/ccwc [OPTION]... [FILE]

Prints the word, line, character, and byte count for FILE. If no FILE, reads from standard input.

Option	Description
-c	print byte counts
-m	print character counts
-l	print newline counts
-w	print word counts

If no options are passed, will by default print word (-w), newlines (-l) and byte (-c) counts.

Examples

A test.txt file is given (provided by the challenge).

# Providing [FILE]
>bin/ccwc test.txt
    7145   58164  342190 test.txt

# No [FILE], read from stdin
>bin/ccwc test.txt | ccwc -l
    7145
