16// //
17// TTabCom //
18// //
19// This class performs basic tab completion. //
20// You should be able to hit [TAB] to complete a partially typed: //
21// //
22// username //
23// environment variable //
24// preprocessor directive //
25// pragma //
26// filename (with a context-sensitive path) //
27// public member function or data member (including base classes) //
28// global variable, function, or class name //
29// //
30// Also, something like //
31// //
32// someObject->Func([TAB] //
33// someObject.Func([TAB] //
34// someClass::Func([TAB] //
35// someClass var([TAB] //
36// new someClass([TAB] //
37// //
38// will print a list of prototypes for the indicated //
39// method or constructor. //
40// //
41// Current limitations and bugs: //
42// //
43// 1. you can only use one member access operator at a time. //
44// eg, this will work: gROOT->GetListOfG[TAB] //
45// but this will not: gROOT->GetListOfGlobals()->Conta[TAB] //
46// //
47// 2. nothing is guaranteed to work on windows //
48// (for one thing, /bin/env and /etc/passwd are hardcoded) //
49// //
50// 3. CINT shortcut #2 is deliberately not supported. //
51// (using "operator.()" instead of "operator->()") //
52// //
53// 4. most identifiers (including C++ identifiers, usernames, //
54// environment variables, etc) //
55// are restriceted to this character set: [_a-zA-Z0-9] //
56// therefore, you won't be able to complete things like //
57// //
58// operator new //
59// operator+ //
60// etc //
61// //
62// 5. ~whatever[TAB] always tries to complete a username. //
63// use whitespace (~ whatever[TAB]) if you want to complete a global //
64// identifier. //
65// //
66// 6. CINT shortcut #3 is not supported when trying to complete //
67// the name of a global object. (it is supported when trying to //
68// complete a member of a global object) //
69// //
70// 7. the list of #pragma's is hardcoded //
71// (ie not obtained from the interpreter at runtime) //
72// ==> user-defined #pragma's will not be recognized //
73// //
74// 8. the system include directories are also hardcoded //
75// because i don't know how to get them from the interpreter. //
76// fons, maybe they should be #ifdef'd for the different sytems? //
77// //
78// 9. the TabCom.FileIgnore resource is always applied, even if you //
79// are not trying to complete a filename. //
80// //
81// 10. anything in quotes is assumed to be a filename //
82// so (among other things) you can't complete a quoted class name: //
83// eg, TClass class1( "TDict[TAB] //
84// this won't work... looks for a file in pwd starting with TDict //
85// //
86// 11. the prototypes tend to omit the word "const" a lot. //
87// this is a problem with ROOT or CINT. //
88// //
89// 12. when listing ambiguous matches, only one column is used, //
90// even if there are many completions. //
91// //
92// 13. anonymous objects are not currently identified //
93// so, for example, //
94// //
95// root> printf( TString([TAB //
96// //
97// gives an error message instead of listing TString's constructors. //
98// (this could be fixed) //
99// //
100// 14. the routine that adds the "appendage" isn't smart enough to know //
101// if it's already there: //
102// //
103// root> TCanvas::Update() //
104// press [TAB] here ^ //
105// root> TCanvas::Update()() //
106// (this could be fixed) //
107// //
108// 15. the appendage is only applied if there is exactly 1 match. //
109// eg, this //
110// //
111// root> G__at[TAB] //
112// root> G__ateval //
113// //
114// happens instead of this //
115// //
116// root> G__at[TAB] //
117// root> G__ateval( //
118// //
119// because there are several overloaded versions of G__ateval(). //
120// (this could be fixed) //
