Combined options

[dsciarra]

The following commands in the ripgrep root folder return different results.

rg -rni hello
globset/src/glob.rs
1166: matches!(matchpat1, "*ni.txt", "ni.txt");
1167: matches!(matchpat2, "*ni.txt", "gareth_says_ni.txt");
1168: matches!(matchpat3, "*ni.txt", "some/path/to/ni.txt");
1169: matches!(matchpat4, "*ni.txt", "some\path\to\ni.txt");
1170: matches!(matchpat5, "*ni.txt", "/an/absolute/path/to/ni.txt");
1171: matches!(matchpat6, "*some/path/to/ni.txt", "some/path/to/ni.txt");
1172: matches!(matchpat7, "*some/path/to/ni.txt",
1173: "a/bigger/some/path/to/ni.txt");
1223: nmatches!(matchnot16, "*ni.txt", "ni.txt-and-then-some");
1224: nmatches!(matchnot17, "*ni.txt", "goodbye.txt");
1225: nmatches!(matchnot18, "*some/path/to/ni.txt",
1226: "some/path/to/ni.txt-and-then-some");
1227: nmatches!(matchnot19, "*some/path/to/ni.txt",
1228: "some/other/path/to/ni.txt");

whereas

rg -r -n -i hello
globset/src/glob.rs
1166: matches!(matchpat1, "*hello.txt", "hello.txt");
1167: matches!(matchpat2, "*hello.txt", "gareth_says_hello.txt");
1168: matches!(matchpat3, "*hello.txt", "some/path/to/hello.txt");
1169: matches!(matchpat4, "*hello.txt", "some\path\to\hello.txt");
1170: matches!(matchpat5, "*hello.txt", "/an/absolute/path/to/hello.txt");
1171: matches!(matchpat6, "*some/path/to/hello.txt", "some/path/to/hello.txt");
1172: matches!(matchpat7, "*some/path/to/hello.txt",
1173: "a/bigger/some/path/to/hello.txt");
1223: nmatches!(matchnot16, "*hello.txt", "hello.txt-and-then-some");
1224: nmatches!(matchnot17, "*hello.txt", "goodbye.txt");
1225: nmatches!(matchnot18, "*some/path/to/hello.txt",
1226: "some/path/to/hello.txt-and-then-some");
1227: nmatches!(matchnot19, "*some/path/to/hello.txt",
1228: "some/other/path/to/hello.txt");

grep returns in both cases the same result.

The -r option for rg doesn't work like the one for grep:

-r, --replace <ARG>                     
        Replace every match with the string given when printing results. Neither this flag nor
        any other flag will modify your files.
        
        Capture group indices (e.g., $5) and names (e.g., $foo) are supported in the replacement
        string.
        
        Note that the replacement by default replaces each match, and NOT the entire line. To
        replace the entire line, you should match the entire line.

So when you give it rg -rni hello, you're telling it to replace the string hello in the output by the string ni.

rg -r -n -i hello should work the same way, except it should replace hello by -n. The fact that it doesn't is a bug, probably in clap (the argument-handling library rg uses) — maybe #482.
