Parsing

fixed

• echo -na $USER
• echo -na test$USER
• echo -na $USERtest
• echo -na $USER $USER
• echo -na "test"
• echo -nat "hello world"
• echo -na "$USER"
• echo -na "test$USER"
• echo -na $USER$USER
• echo -na "$USER$USER"
• echo -na "$USER $USER"
• echo -na "test test"
• echo -na "$USERtest"
• echo -na -t "hello world'" 'helloworad "'
• echo "test" (no optinos)
• "echo" '-n' "' hello" ' "world'
• echo -na "$USER1_"
• echo -na "$USER_"
• echo -na "$USER test" test
• echo -na "$USER_" test "test"
• echo "hello"world
• echo "hello""world"'test'
• echo ' $USER"world"'test
• echo "$USER"'$USER'
• echo "'test' $USER "hello ' $USER"world"'test

pipes

• Multiple redirection if there is an error with file oppening have to handle. Same for heredoc

Quotes in env_vars

• export sq="'"
• echo $sq test$sq'hello'world
• export dq='"'
• echo $dq test$dq'hello'world

redirection

cat > outfile < Makefile cat > outfile > outfile2 < Makefile > outfile3 < outfile > outfile2 < src/minishell/main.c cat >> outfile >> outfile2 < Makefile >> outfile3 < outfile > outfile2 < src/minishell/main.c echo >test"$USER" echo >>test"$USER" echo ">>test"$USER"" echo ">>t"test

parsing

• return error when encounter \ or ; and unclosed quotes when parsing arguments
• fix if there is nothing at all
• fix if theres nothing between pipes

cd

• cd multiple arguments has special message
• cd with 2 arguemts
  • oh-my-zsh
  • ibm docs
• cd with > 2 arguemts
• cd - (goes to OLDPWD)
• cd no argument return to root
• cd check if file is file or directory
• cd test test2
• cd -n test
• cd -n -n
• cd < test -n abc
• cd < test ~

parsing: single character in the beginning

< test.txt echo hello (valid) e test (invalid)

To not fix

Trimming spaces in env_vars when not within quotes

• export bad=" bad "
• echo $bad
• echo "$bad"

To do

• header
• Makefile
• styling
• maybe signals in heredoc
