42-minishell

42 cursus project: Write a simple shell like bash. Learning about process and file descriptors

TODO:

• piped commands exit_codes + redir exit_codes

• export something without key=value pair should do nothing

• error syntax when just pipe symbol

• handle export without args + export whithout value

• echo '\'

• echo "hello\newline"

• export VARIABLE=value; echo VARIABLE

• echo "a\\ \ b c\" \'$SHELL\'"

• export TEST="ls -l | cat -e"

• handle SIGINT and SIGTERM in parse_cmdline(). Test: pwd; find /; date

• disable raw_mode when parsing

• improve signal handler printing characters + g_sig.sigint flag is missing

25/05:

• exit codes unset "" test
• export "" test=a
• fix has_syntax_error function
• echo bonjour >>> test
• export test="ab[whitespaces]cd[whitespaces]ef" --> echo $test --> test="ab cd ef"
• error message export $VAR=value if VAR doesn't exist in env
• export $VAR=value
• handle cd with multiples env args: cd $HOME/42cursus --> parsing/interpreter.c/handle_variables()
• echo $USER$var\$USER$USER\$USERtest$USER
• executable with absolut and relative path: cd srcs/ and ../minishell --> parsing/parse_path.c/is_exec_path()
• handle error 126 when not an executable: ./srcs utils/error.c
• . --> exit code 2
• .. --> exit code 127
• echo "bip | bip ; coyotte > < \" "
• cat Makefile | grep pr | head -n 5 | cd file_not_exit --> exit code in pipes
• ls | exit
• pwd ; sleep 10 ; date --> exit code

Final tests ok 30/05:

• ""
• echo bonjour \; ls ---> escape character
• echo bonjour > test\ 1 ---> escape character
• echo $var bonjour ---> whitespace
• export test=" foo bar " ; echo ""$test"" | cat -e
• export test="file1 file2" ; >"$test" ---> error syntax
