The operators permitted in an expression include a subset of the operators permitted in C expressions. For those operators common to both Tcl and C, Tcl applies the same meaning and precedence as the corresponding C operators. The value of an expression is often a numeric result, either an integer or a floating-point value, but may also be a non-numeric value. For example, the expression .PP .CS \fBexpr\fR {8.2 + 6} .CE .PP evaluates to 14.2. Expressions differ from C expressions in the way that operands are specified. Expressions also support non-numeric operands, string comparisons, and some additional operators not found in C. .PP When the result of expression is an integer, it is in decimal form, and when the result is a floating-point number, it is in the form produced by the \fB%g\fR format specifier of \fBformat\fR. .PP .VS "9.0, TIP 526" Unlike with prior versions of Tcl, from Tcl 9.0 onwards, the \fBexpr\fR command only accepts a single argument instead of concatenating an arbitrary number of arguments to form an expression. See \fBCOMPATIBILITY WITH TCL 8.*\fR below for details. .VE "9.0, TIP 526" .VS "TIP 582" At any point in the expression except within double quotes or braces, \fB#\fR is the beginning of a comment, which lasts to the end of the line or the end of the expression, whichever comes first. .VE "TIP 582" .SS OPERANDS .PP |

This also avoids issues that can arise if Tcl is allowed to perform substitution on the value before \fBexpr\fR is called. .PP In the following example, the value of the expression is 11 because the Tcl parser first substitutes \fB$b\fR and \fBexpr\fR then substitutes \fB$a\fR as part of evaluating the expression .QW "$a + 2*4" . Simply enclosing the expression in braces would result in a syntax error as \fB$b\fR does not evaluate to a numeric value. .PP .CS set a 3 set b {$a + 2} \fBexpr\fR $b*4 |

To allow the bytecode compiler to work with an expression as a string literal at compilation time, ensure that it contains no substitutions or that it is enclosed in braces or otherwise quoted to prevent Tcl from performing substitutions, allowing \fBexpr\fR to perform them instead. .PP In general, you should enclose your expression in braces wherever possible, and where not possible, the argument to \fBexpr\fR should be an expression defined elsewhere as simply as possible. It is usually more efficient and safer to use other techniques (e.g., the commands in the \fBtcl::mathop\fR namespace) than it is to do complex expression generation. Storing a complex expression in a variable and using that with \fBexpr\fR is a case which the bytecode compiler also supports well, provided that expression is always evaluated in the same stack context (though the expression could be conveyed across procedure calls and through \fBuplevel\fR calls in between). .SS "COMPATIBILITY WITH TCL 8.*" .PP .VS "9.0, TIP 526" In Tcl 8 and older, the \fBexpr\fR command would concatenate multiple arguments to form the expression; if this behavior is desired in Tcl 9.0 onwards, explicit use of \fBconcat\fR is required (this is also compatible with earlier versions of Tcl) or a double-quoted argument could be used (as whitespace is not generally important in expressions). Note that this style of programming is often a source of bugs, including security bugs, so it is \fInot recommended\fR. For example, instead of this version (supported in Tcl 8 and before): .PP .CS set a 3 set b {$a + 2} \fBexpr\fR $b * 4 .CE .PP you might write: .PP .CS # ... \fBexpr\fR [concat $b * 4] .CE .PP or: .PP .CS # ... \fBexpr\fR "$b * 4" .CE .PP Both of the above cases substitute \fB$b\fR prior to evaluating the expression, and do the building of the expression dynamically making it difficult to avoid compiling the expression on every call to \fBexpr\fR. .PP However, some use cases that \fIare\fR supported may be preferable, such as embedding the use of \fBexpr\fR with a variable argument inside an otherwise constant expression: .PP .CS # ... \fBexpr\fR {[\fBexpr\fR $b] * 4} .CE .PP This changes what value is calculated (in this case, producing \fB20\fR rather than \fB11\fR) because they force the inner expression to be evaluated independently of the outer one; such changes may actually fix more bugs than they cause! Note that this allows the outer expression to be fully compiled, and enables compilation of the inner expression too (which can be cached in some cases). .VE "9.0, TIP 526" .SH EXAMPLES .PP A numeric comparison whose result is 1: .PP .CS \fBexpr\fR {"0x03" > "2"} .CE |
