Update the file headers across all of the LLVM projects in the monorepo to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

Merging the iohandler branch back into main. The many many benefits include: 1 - Input/Output/Error streams are now handled as real streams not a push style input 2 - auto completion in python embedded interpreter 3 - multi-line input for "script" and "expression" commands now allow you to edit previous/next lines using up and down arrow keys and this makes multi-line input actually a viable thing to use 4 - it is now possible to use curses to drive LLDB (please try the "gui" command) We will need to deal with and fix any buildbot failures and tests and arise now that input/output and error are correctly hooked up in all cases. llvm-svn: 200263

#include "lldb/Interpreter/CommandObject.h"
Added support to the expression command for dropping into the REPL at will. "expr -r" does this. It also returns to a REPL if the LLDB command interpreter is neseted inside it, for example in cases where a REPL command resulted in a breakpoint being hit or a crash. llvm-svn: 250780

#include "lldb/Interpreter/OptionGroupBoolean.h"
Updated all commands that use a "--format" / "-f" options to use the new OptionGroupFormat. Updated OptionGroupFormat to be able to also use the "--size" and "--count" options. Commands that use a OptionGroupFormat instance can choose which of the options they want by initializing OptionGroupFormat accordingly. Clients can either get only the "--format", "--format" + "--size", or "--format" + "--size" + "--count". This is in preparation for upcoming chnages where there are alternate ways (GDB format specification) to set a format. llvm-svn: 142911

#include "lldb/Interpreter/OptionGroupFormat.h"
<rdar://problem/12028723> Adding useful formatting options to the expression (expr) command. As a side effect of this change, the -d option now supports the same three-values enumeration that frame variables uses (run, don't run, none) instead of a boolean like it did previously These options do not apply to print, p or po because these are aliased to not take any options. In order to use them, use expression or expr. llvm-svn: 171993

Convert option tables to ArrayRefs. This change is very mechanical. All it does is change the signature of `Options::GetDefinitions()` and `OptionGroup:: GetDefinitions()` to return an `ArrayRef<OptionDefinition>` instead of a `const OptionDefinition *`. In the case of the former, it deletes the sentinel entry from every table, and in the case of the latter, it removes the `GetNumDefinitions()` method from the interface. These are no longer necessary as `ArrayRef` carries its own length. In the former case, iteration was done by using a sentinel entry, so there was no knowledge of length. Because of this the individual option tables were allowed to be defined below the corresponding class (after all, only a pointer was needed). Now, however, the length must be known at compile time to construct the `ArrayRef`, and as a result it is necessary to move every option table before its corresponding class. This results in this CL looking very big, but in terms of substance there is not much here. Differential revision: https://reviews.llvm.org/D24834 llvm-svn: 282188

Rename Error -> Status. This renames the LLDB error class to Status, as discussed on the lldb-dev mailing list. A change of this magnitude cannot easily be done without find and replace, but that has potential to catch unwanted occurrences of common strings such as "Error". Every effort was made to find all the obvious things such as the word "Error" appearing in a string, etc, but it's possible there are still some lingering occurences left around. Hopefully nothing too serious. llvm-svn: 302872

Added initial code completion support for the `expr` command Summary: This patch adds initial code completion support for the `expr` command. We now have a completion handler in the expression CommandObject that essentially just attempts to parse the given user expression with Clang with an attached code completion consumer. We filter and prepare the code completions provided by Clang and send them back to the completion API. The current completion is limited to variables that are in the current scope. This includes local variables and all types used by local variables. We however don't do any completion of symbols that are not used in the local scope (or in some other way already in the ASTContext). This is partly because there is not yet any code that manually searches for additiona information in the debug information. Another cause is that for some reason the existing code for loading these additional symbols when requested by Clang doesn't seem to work. This will be fixed in a future patch.

Get rid of the C-string parameter in DoExecute Summary: This patch gets rid of the C-string parameter in the RawCommandObject::DoExecute function, making the code simpler and less memory unsafe. There seems to be a assumption in some command objects that this parameter could be a nullptr, but from what I can see the rest of the API doesn't actually allow this (and other command objects and related code pieces dereference this parameter without any checks). Especially CommandObjectRegexCommand has error handling code for a nullptr that is now gone.
