Parser Bonus (*)

[edu-bm7]

Wildcards * should work for the current working directory.

Right now I'm working on tokenizing the * as a separated token to be expanded during the parser phase so we know our current working directory for that part of the execution phase(if we changed directory in the middle of execution the * should be used in another directory, if it is after the cd command), so thats why we cant expand directly on the tokenizing phase.

The wild card tokenization part is done. Now we should leave the rest to the parser phase.

The expansion of the wildcards is completed, proceeding to test it

After extensively testing, the parser is working as expetected, here the tests that I did:

1. Basic Wildcard Tests:
   • Files: abc.txt, axc.txt, a123c.txt, bc.txt, ac.txt, a.c.txt
   • Pattern: a*c.txt
   • Expected Matches: abc.txt, axc.txt, a123c.txt, ac.txt, a.c.txt
2. Wildcard At The Beginning:
   • Files: file.txt, myfile.txt, yourfile.txt, afile.txt
   • Pattern: *file.txt
   • Expected Matches: All of them
3. Wildcard At The End:
   • Files: notes.txt, notes.doc, notes.png, notes
   • Pattern: notes.*
   • Expected Matches: notes.txt, notes.doc, notes.png
4. Wildcard At Both Ends:
   • Files: main.c, maintest.c, testmain.c, maintestmain.c
   • Pattern: main.c
   • Expected Matches: All of them
5. Multiple Wildcards:
   • Files: a.txt, ab.txt, abc.txt, abcd.txt, abcde.txt
   • Pattern: abc*.txt
   • Expected Matches: abc.txt, abcd.txt, abcde.txt
6. Only Wildcard:
   • Files: Any set of files
   • Pattern: *
   • Expected Matches: All files
7. Consecutive Wildcards (Although rarely used in practice, it's a good edge case):
   • Files: a.txt, aa.txt, aaa.txt
   • Pattern: a**.txt
   • Expected Matches: All of them
8. Wildcards with Special Characters:
   • Files: a$.txt, a$1.txt, a$$.txt, a$123.txt
   • Pattern: a$*.txt
   • Expected Matches: All of them
9. No Matches:
   • Files: file1.txt, file2.txt
   • Pattern: file3.txt
   • Expected Matches: None
10. Wildcard in Middle:
    • Files: file.txt, fileXtxt, fileXXtxt, fileYtxt
    • Pattern: file*txt
    • Expected Matches: All of them
11. Edge Case with Multiple Wildcards:
    • Files: fileabcde.txt, filebcde.txt, filecde.txt, filede.txt, filee.txt
    • Pattern: fileabcd*e.txt
    • Expected Matches: fileabcde.txt
12. Multiple Consecutive Wildcards:
    • Files: axb.txt, a.txt, ab.txt, a1234b.txt
    • Pattern: a***b.txt
    • Expected Matches: axb.txt, ab.txt, a1234b.txt
13. No File Extension:
    • Files: document, doc, docu, documentary
    • Pattern: doc*
    • Expected Matches: All of them
