ft_ls

The ft_ls project aims to reproduce a minimalist version of the ls command.

Installation

To install, clone this project then make. Done ! You can enter ./ft_ls to see if it works.

Ft_Ls Tester

I did a tester ! You can use it on your ft_ls too. To use it, place it in the directory of your ft_ls, and launch it with ./tester.sh. It works only if your executable is named ft_ls !

Man

You can also see this man by typing ft_ls --help

Usage: ls [OPTION]... [FILE]...
List information about the FILEs (the current directory by default).
Sort entries alphabetically if none of -cftuvSUX nor --sort is specified.

Mandatory arguments to long options are mandatory for short options too.
	-a, --all                  do not ignore entries starting with .
	-A, --almost-all           do not list implied . and ..
	    --color                colorize the output
	-d, --directory            list directories themselves, not their contents
	    --dino                 translate every entry names to "groar" base
	-f                         do not sort, enable -aU, disable -ls --color
	-g                         like -l, but do not list owner
	-l                         use a long listing format
	-m                         fill width with a comma separated list of entries
	-N, --literal              print entry names without quoting
	-Q, --quote-name           enclose entry names in double quotes
	-r, --reverse              reverse order while sorting
	-R, --recursive            list subdirectories recursively
	-t                         sort by time, newest first
	-u                         with -lt: sort by, and show, access time;
                               with -l: show access time and sort by name;
	                           otherwise: sort by access time, newest first
	-U                         do not sort; list entries in directory order
	    --help     display this help and exit
		--version  output version information and exit

Exit status:
0  if OK,
1  if minor problems (e.g., cannot access subdirectory),
2  if serious trouble (e.g., cannot access command-line argument).

Implementation

I choose to implement certain things and not implement other things on this project.

First, I implemented all the mandatory parts, which is :

• Handling of the options -l, -R, -a, -r and -t.
• Handling of the multi-columns display for -l.

I also did some of the proposed bonuses, like :

• Management of the columns without -l.
• Management of views in color.
• Management of proposed options -g, -d, -f and -u.
• Optimization : My implementation is nearly as fast as the basic ls.

I even did non-proposed bonuses :

• Creation of a man page (./ft_ls --help)
• Management of options -A, --color, -m, -N, -Q and -U.
• Creation of the option --dino, which ls never implemented and it's scandalous.
• Management of verbose options (or long options), like --recursive or just --.
• Management of errors the same way as ls, like when you do ls --re for example.

And, unlike ls, I do not have any still reachable when exiting :)
