# Minishell
=======
A lot of amazing shell stuff
## Dependencies
- libreadline-dev
- libncurses-dev
## merge info
origen/quinten -> willem:
ik het TokenType veranderd naar t_token_type vanwege de norm
Volgens mij had je een off-by-one error in ft_lexer_readword:85
je moet de null terminator ook meerekenen in de malloc size
```c
if (!(word = malloc(sizeof(char) * (i + 1))))
```
## TODO
- Find absolute path for command input ('/', './', 'cmd')
- Add heredoc to tokenizer
- Environment to `t_list`
- Get environment array (export)
- Preliminary signals
- Define struct for commands, something like (
```c
typedef struct s_command
{
char *command;
char *path;
char **args;
int fd_in;
int fd_out;
} t_command;
```
)
- Make the `executor`, run a command
- Make a parser to create a command list
- Add redirects, appends, pipe etc. File descriptor functions
- Expand \$ vars & support \$?
- __Bonus:__ Command tree for &&, ||, *
