minishell's Issues

Infinite loop

infinite loop of "None" when passing a command to minishell via pipe, i.e. : echo -e "echo\tmish" | ./minishell

Environment variable name within single quotes should not be expanded

input -> $HOME'$PWD'
expected output -> /Users/amait-ou$PWD
wrong output -> /Users/amait-ou'/Users/amait-ou/Desktop/Minishell'

segmentation fault

quotes_removal function causes minishell to segfault

'$PWD' => [1] 6278 segmentation fault ./minishell

LEXER ERROR

'"'$PWD $HOME'"' is splitted like this :
[.] '"'
[.] /Users/bbouagou/projetcs/Minishell
[.] /Users/bbouagou'"'

instead it should split like this:
[.] '"'/Users/bbouagou/projetcs/Minishell
[.] /Users/bbouagou'"'

Lexer error

' $PWD '$HOME' '$LOL'' is splitted like this:

[.] ' $PWD '
[.] $HOME' '
[.] $LOL''

A SEGV occurs when I enter only the * symbol

when entering a star in the shell it gives a segmentation fault instead of showing all files and dirs

<< "$PWD" (the delimiter is considered as a string when it is after a heredoc)

<< "$PWD" should not be expanded

Fix this $(PWD)

$(PWD)

your input -> $)
expected output -> /Users/amait-ou/Desktop/Minishell

echo $PWD* should expand without the star at the end

input -> echo $PWD*
expected output :
[.] echo
[.] /Users/amait-ou/Desktop/Minishell
Your Output :
[.] echo
[.] /Users/amait-ou/Desktop/Minishell*

when pressing entering only *, the wildcard should not print hidden files/folders

echo * should expand only for showed files not hidden ones too
