This is mostly helpful when developing tests where the test itself contains some rust syntax as a string. --- crates/ra_ide_api/tests/test/main.rs | 118 +++++++++++++++++++++++++++++++++++ 1 file changed, 118 insertions(+) (limited to 'crates/ra_ide_api/tests/test') diff --git a/crates/ra_ide_api/tests/test/main.rs b/crates/ra_ide_api/tests/test/main.rs index b0c80e255..0f0766f62 100644 --- a/crates/ra_ide_api/tests/test/main.rs +++ b/crates/ra_ide_api/tests/test/main.rs @@ -272,3 +272,121 @@ EXPR_STMT@[16; 58) .trim() ); } + +#[test] +fn test_syntax_tree_inside_string() { + let (analysis, range) = single_file_with_range( + r#"fn test() { + assert!(" +<|>fn foo() { +}<|> +fn bar() { +} + ", ""); +}"# + .trim(), + ); + let syn = analysis.syntax_tree(range.file_id, Some(range.range)); + assert_eq!( + syn.trim(), + r#" +SOURCE_FILE@[0; 12) + FN_DEF@[0; 12) + FN_KW@[0; 2) + WHITESPACE@[2; 3) + NAME@[3; 6) + IDENT@[3; 6) "foo" + PARAM_LIST@[6; 8) + L_PAREN@[6; 7) + R_PAREN@[7; 8) + WHITESPACE@[8; 9) + BLOCK@[9; 12) + L_CURLY@[9; 10) + WHITESPACE@[10; 11) + R_CURLY@[11; 12) +"# + .trim() + ); + + // With a raw string + let (analysis, range) = single_file_with_range( + r###"fn test() { + assert!(r#" +<|>fn foo() { +}<|> +fn bar() { +} + "#, ""); +}"### + .trim(), + ); + let syn = analysis.syntax_tree(range.file_id, Some(range.range)); + assert_eq!( + syn.trim(), + r#" +SOURCE_FILE@[0; 12) + FN_DEF@[0; 12) + FN_KW@[0; 2) + WHITESPACE@[2; 3) + NAME@[3; 6) + IDENT@[3; 6) "foo" + PARAM_LIST@[6; 8) + L_PAREN@[6; 7) + R_PAREN@[7; 8) + WHITESPACE@[8; 9) + BLOCK@[9; 12) + L_CURLY@[9; 10) + WHITESPACE@[10; 11) + R_CURLY@[11; 12) +"# + .trim() + ); + + // With a raw string + let (analysis, range) = single_file_with_range( + r###"fn test() { + assert!(r<|>#" +fn foo() { +} +fn bar() { +}"<|>#, ""); +}"### + .trim(), + ); + let syn = analysis.syntax_tree(range.file_id, Some(range.range)); + assert_eq!( + syn.trim(), + r#" +SOURCE_FILE@[0; 25) + FN_DEF@[0; 12) + FN_KW@[0; 2) + WHITESPACE@[2; 3) + NAME@[3; 6) + IDENT@[3; 6) "foo" + PARAM_LIST@[6; 8) + L_PAREN@[6; 7) + R_PAREN@[7; 8) + WHITESPACE@[8; 9) + BLOCK@[9; 12) + L_CURLY@[9; 10) + WHITESPACE@[10; 11) + R_CURLY@[11; 12) + WHITESPACE@[12; 13) + FN_DEF@[13; 25) + FN_KW@[13; 15) + WHITESPACE@[15; 16) + NAME@[16; 19) + IDENT@[16; 19) "bar" + PARAM_LIST@[19; 21) + L_PAREN@[19; 20) + R_PAREN@[20; 21) + WHITESPACE@[21; 22) + BLOCK@[22; 25) + L_CURLY@[22; 23) + WHITESPACE@[23; 24) + R_CURLY@[24; 25) + +"# + .trim() + ); +} -- cgit v1.2.3
