"A summary string is a way to extract information from variables in order to present them using a summary.\n"
|
|
"Summary strings contain static text, variables, scopes and control sequences:\n"
|
|
" - Static text can be any sequence of non-special characters, i.e. anything but '{', '}', '$', or '\\'.\n"
|
|
" - Variables are sequences of characters beginning with ${, ending with } and that contain symbols in the format described below.\n"
|
|
" - Scopes are any sequence of text between { and }. Anything included in a scope will only appear in the output summary if there were no errors.\n"
|
|
" - Control sequences are the usual C/C++ '\\a', '\\n', ..., plus '\\$', '\\{' and '\\}'.\n"
|
|
"A summary string works by copying static text verbatim, turning control sequences into their character counterpart, expanding variables and trying to expand scopes.\n"
|
|
"A variable is expanded by giving it a value other than its textual representation, and the way this is done depends on what comes after the ${ marker.\n"
|
|
"The most common sequence if ${var followed by an expression path, which is the text one would type to access a member of an aggregate types, given a variable of that type"
|
|
" (e.g. if type T has a member named x, which has a member named y, and if t is of type T, the expression path would be .x.y and the way to fit that into a summary string would be"
|
|
" ${var.x.y}). You can also use ${*var followed by an expression path and in that case the object referred by the path will be dereferenced before being displayed."
|
|
" If the object is not a pointer, doing so will cause an error. For additional details on expression paths, you can type 'help expr-path'. \n"
|
|
"By default, summary strings attempt to display the summary for any variable they reference, and if that fails the value. If neither can be shown, nothing is displayed."
|
|
"In a summary string, you can also use an array index [n], or a slice-like range [n-m]. This can have two different meanings depending on what kind of object the expression"
|
|
" path refers to:\n"
|
|
" - if it is a scalar type (any basic type like int, float, ...) the expression is a bitfield, i.e. the bits indicated by the indexing operator are extracted out of the number"
|
|
" and displayed as an individual variable\n"
|
|
" - if it is an array or pointer the array items indicated by the indexing operator are shown as the result of the variable. if the expression is an array, real array items are"
|
|
" printed; if it is a pointer, the pointer-as-array syntax is used to obtain the values (this means, the latter case can have no range checking)\n"
|
|
"If you are trying to display an array for which the size is known, you can also use [] instead of giving an exact range. This has the effect of showing items 0 thru size - 1.\n"
|
|
"Additionally, a variable can contain an (optional) format code, as in ${var.x.y%code}, where code can be any of the valid formats described in 'help format', or one of the"
|
|
" special symbols only allowed as part of a variable:\n"
|
|
" %V: show the value of the object by default\n"
|
|
" %S: show the summary of the object by default\n"
|
|
" %@: show the runtime-provided object description (for Objective-C, it calls NSPrintForDebugger; for C/C++ it does nothing)\n"
|
|
" %L: show the location of the object (memory address or a register name)\n"
|
|
" %#: show the number of children of the object\n"
|
|
" %T: show the type of the object\n"
|
|
"Another variable that you can use in summary strings is ${svar . This sequence works exactly like ${var, including the fact that ${*svar is an allowed sequence, but uses"
|
|
" the object's synthetic children provider instead of the actual objects. For instance, if you are using STL synthetic children providers, the following summary string would"
|
