WebThe type declaration states that the function is a right associative infix operator with priority 8: this states that x*x^(n-1) is equivalent to x*(x^(n-1)) as opposed to (x*x)^(n-1). This operator is pre-defined in StdEnv, the Clean standard library. How Clean works. Computing is based on graph rewriting and reduction. WebThis operator filters findings that have any overlap with the supplied regular expression. For example, if you use pattern-regex to detect Foo==1.1.1 and it also detects Foo-Bar==3.0.8 and Bar-Foo==3.0.8, you can use pattern-not-regex to filter the unwanted findings. Example Try this pattern in the Semgrep Playground. focus-metavariable

WebMost programming languages support binary operators and a few unary operators, with a few supporting more operands, such as the ?: operator in C, which is ternary. There are prefix unary operators, such as unary minus -x, and postfix unary operators, such as post-increment x++; and binary operations are infix, such as x + y or x = y. WebTwo regular expressions may be joined by the infix operator ; the resulting regular expression matches any string matching either subexpression. For example, abba cde matches either the string abba or the string cde.
