2024-02-27Start to clean up the process of defining command arguments. (#83097)jimingham1-12/+1
Partly, there's just a lot of unnecessary boiler plate. It's also possible to define combinations of arguments that make no sense (e.g. eArgRepeatPlus followed by eArgRepeatPlain...) but these are never checked since we just push_back directly into the argument definitions. This commit is step 1 of this cleanup - do the obvious stuff. In it, all the simple homogenous argument lists and the breakpoint/watchpoint ID/Range types, are set with common functions. This is an NFC change, it just centralizes boiler plate. There's no checking yet because you can't get a single argument wrong. The end goal is that all argument definition goes through functions and m_arguments is hidden so that you can't define inconsistent argument sets.
2023-10-30[lldb] Part 2 of 2 - Refactor `CommandObject::DoExecute(...)` return `void` ↵Pete Lawrence1-5/+3
(not `bool`) (#69991) [lldb] Part 2 of 2 - Refactor `CommandObject::DoExecute(...)` to return `void` instead of ~~`bool`~~ Justifications: - The code doesn't ultimately apply the `true`/`false` return values. - The methods already pass around a `CommandReturnObject`, typically with a `result` parameter. - Each command return object already contains: - A more precise status - The error code(s) that apply to that status Part 1 refactors the `CommandObject::Execute(...)` method. - See [https://github.com/llvm/llvm-project/pull/69989](https://github.com/llvm/llvm-project/pull/69989) rdar://117378957

2020-01-24[lldb][NFC] Fix all formatting errors in .cpp file headersRaphael Isemann1-1/+1
Summary: A *.cpp file header in LLDB (and in LLDB) should like this: ``` //===-- TestUtilities.cpp -------------------------------------------------===// ``` However in LLDB most of our source files have arbitrary changes to this format and these changes are spreading through LLDB as folks usually just use the existing source files as templates for their new files (most notably the unnecessary editor language indicator `-*- C++ -*-` is spreading and in every review someone is pointing out that this is wrong, resulting in people pointing out that this is done in the same way in other files). This patch removes most of these inconsistencies including the editor language indicators, all the different missing/additional '-' characters, files that center the file name, missing trailing `===//` (mostly caused by clang-format breaking the line).

We should in general not allow external code to fiddle with the internals of CompletionRequest, but until this is gone let's at least provide a utility function that makes this less dangerous. This also now correct updates the partially parsed argument list, but it doesn't seem to be used by anything that is behind one of the current shift/SetCursorIndex calls, so this doesn't seeem to fix any currently used completion. llvm-svn: 372556

2019-08-22[lldb][NFC] Remove WordComplete mode, make result array indexed from 0 and ↵Raphael Isemann1-4/+4
remove any undocumented/redundant return values Summary: We still have some leftovers of the old completion API in the internals of LLDB that haven't been replaced by the new CompletionRequest. These leftovers are: * The return values (int/size_t) in all completion functions. * Our result array that starts indexing at 1. * `WordComplete` mode. I didn't replace them back then because it's tricky to figure out what exactly they are used for and the completion code is relatively untested. I finally got around to writing more tests for the API and understanding the semantics, so I think it's a good time to get rid of them. A few words why those things should be removed/replaced: * The return values are really cryptic, partly redundant and rarely documented. They are also completely ignored by Xcode, so whatever information they contain will end up breaking Xcode's completion mechanism. They are also partly impossible to even implement as we assign negative values special meaning and our completion API sometimes returns size_t. Completion functions are supposed to return -2 to rewrite the current line. We seem to use this in some untested code path to expand the history repeat character to the full command, but I haven't figured out why that doesn't work at the moment. Completion functions return -1 to 'insert the completion character', but that isn't implemented (even though we seem to activate this feature in LLDB sometimes). All positive values have to match the number of results. This is obviously just redundant information as the user can just look at the result list to get that information (which is what Xcode does). * The result array that starts indexing at 1 is obviously unexpected. The first element of the array is reserved for the common prefix of all completions (e.g. "foobar" and "footar" -> "foo"). The idea is that we calculate this to make the life of the API caller easier, but obviously forcing people to have 1-based indices is not helpful (or even worse, forces them to manually copy the results to make it 0-based like Xcode has to do). * The `WordComplete` mode indicates that LLDB should enter a space behind the completion. The idea is that we let the top-level API know that we just provided a full completion. Interestingly we `WordComplete` is just a single bool that somehow represents all N completions. And we always provide full completions in LLDB, so in theory it should always be true. The only use it currently serves is providing redundant information about whether we have a single definitive completion or not (which we already know from the number of results we get). This patch essentially removes `WordComplete` mode and makes the result array indexed from 0. It also removes all return values from all internal completion functions. The only non-redundant information they contain is about rewriting the current line (which is broken), so that functionality was moved to the CompletionRequest API. So you can now do `addCompletion("blub", "description", CompletionMode::RewriteLine)` to do the same. For the SB API we emulate the old behaviour by making the array indexed from 1 again with the common prefix at index 0. I didn't keep the special negative return codes as we either never sent them before (e.g. -2) or we didn't even implement them in the Editline handler (e.g. -1). I tried to keep this patch minimal and I'm aware we can probably now even further simplify a bunch of related code, but I would prefer doing this in follow-up NFC commits Reviewers: JDevlieghere Reviewed By: JDevlieghere Subscribers: arphaman, abidh, lldb-commits Tags: #lldb Differential Revision: https://reviews.llvm.org/D66536 llvm-svn: 369624

Summary: Right now our CommandOptions.inc only generates the initializer for the options list but not the array declaration boilerplate around it. As the array definition is identical for all arrays, we might as well also let the CommandOptions.inc generate it alongside the initializers. This patch will also allow us to generate additional declarations related to that option list in the future (e.g. a enum class representing the specific options which would make our handling code less prone). This patch also fixes a few option tables that didn't follow our naming style.

2019-07-12[lldb] Let table gen create command option initializers.Raphael Isemann1-5/+2
Summary: We currently have man large arrays containing initializers for our command options. These tables are tricky maintain as we don't have any good place to check them for consistency and it's also hard to read (`nullptr, {}, 0` is not very descriptive). This patch fixes this by letting table gen generate those tables. This way we can have a more readable syntax for this (especially for all the default arguments) and we can let TableCheck check them for consistency (e.g. an option with an optional argument can't have `eArgTypeNone`, naming of flags', etc.). Also refactoring the related data structures can now be done without changing the hundred of option initializers. For example, this line: ``` {LLDB_OPT_SET_ALL, false, "hide-aliases", 'a', OptionParser::eNoArgument, nullptr, {}, 0, eArgTypeNone, "Hide aliases in the command list."}, ``` becomes this: ``` def hide_aliases : Option<"hide-aliases", "a">, Desc<"Hide aliases in the command list.">; ``` For now I just moved a few initializers to the new format to demonstrate the change. I'll slowly migrate the other option initializers tables in separate patches.

2019-04-10[NFC] Remove ASCII lines from commentsJonas Devlieghere1-2/+0
A lot of comments in LLDB are surrounded by an ASCII line to delimit the begging and end of the comment. Its use is not really consistent across the code base, sometimes the lines are longer, sometimes they are shorter and sometimes they are omitted. Furthermore, it looks kind of weird with the 80 column limit, where the comment actually extends past the line, but not by much. Furthermore, when /// is used for Doxygen comments, it looks particularly odd. And when // is used, it incorrectly gives the impression that it's actually a Doxygen comment. I assume these lines were added to improve distinguishing between comments and code. However, given that todays editors and IDEs do a great job at highlighting comments, I think it's worth to drop this for the sake of consistency. The alternative is fixing all the inconsistencies, which would create a lot more churn. Differential revision: https://reviews.llvm.org/D60508 llvm-svn: 358135
2019-02-13Replace 'ap' with 'up' suffix in variable names. (NFC)Jonas Devlieghere1-3/+4
The `ap` suffix is a remnant of lldb's former use of auto pointers, before they got deprecated. Although all their uses were replaced by unique pointers, some variables still carried the suffix. In r353795 I removed another auto_ptr remnant, namely redundant calls to ::get for unique_pointers. Jim justly noted that this is a good opportunity to clean up the variable names as well. I went over all the changes to ensure my find-and-replace didn't have any undesired side-effects. I hope I didn't miss any, but if you end up at this commit doing a git blame on a weirdly named variable, please know that the change was unintentional. llvm-svn: 353912

2018-07-02Refactoring for for the internal command line completion API (NFC)Raphael Isemann1-19/+9
Summary: This patch refactors the internal completion API. It now takes (as far as possible) a single CompletionRequest object instead o half a dozen in/out/in-out parameters. The CompletionRequest contains a common superset of the different parameters as far as it makes sense. This includes the raw command line string and raw cursor position, which should make the `expr` command possible to implement (at least without hacks that reconstruct the command line from the args). This patch is not intended to change the observable behavior of lldb in any way. It's also as minimal as possible and doesn't attempt to fix all the problems the API has. Some Q&A: Q: Why is this not fixing all the problems in the completion API? A: Because is a blocker for the expr command completion which I want to get in ASAP. This is the smallest patch that unblocks the expr completion patch and which allows trivial refactoring in the future. The patch also doesn't really change the internal information flow in the API, so that hopefully saves us from ever having to revert and resubmit this humongous patch. Q: Can we merge all the copy-pasted code in the completion methods (like computing the current incomplete arg) into CompletionRequest class? A: Yes, but it's out of scope for this patch. Q: Why the `word_complete = request.GetWordComplete(); ... ` pattern? A: I don't want to add a getter that returns a reference to the internal integer. So we have to use a temporary variable and the Getter/Setter instead. We don't throw exceptions from what I can tell, so the behavior doesn't change. Q: Why are we not owning the list of matches? A: Because that's how the previous API works. But that should be fixed too (in another patch). Q: Can we make the constructor simpler and compute some of the values from the plain command? A: I think this works, but I rather want to have this in a follow up commit. Especially when making nested request it's a bit awkward that the parsed arguments behave as both input/output (as we should in theory propagate the changes on the nested request back to the parent request if we don't want to change the behavior too much). Q: Can't we pass one const request object and then just return another result object instead of mixing them together in one in/out parameter? A: It's hard to get keep the same behavior with that pattern, but I think we can also get a nice API with just a single request object. If we make all input parameters read-only, we have a clear separation between what is actually an input and what an output parameter (and hopefully we get rid of the in-out parameters). Q: Can we throw out the 'match' variables that are not implemented according to the comment? A: We currently just forward them as in the old code to the different methods, even though I think they are really not used. We can easily remove and readd them once every single completion method just takes a CompletionRequest, but for now I prefer NFC behavior from the perspective of the API user.

2016-09-22Convert option tables to ArrayRefs.Zachary Turner1-2/+6
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

The next step is to actually turn CommandAlias into a full-blown CommandObject citizen. This is tricky given the current architecture of the CommandInterpreter but I think I have found a reasonable path forward. The current plan is to make class CommandAlias : public CommandObject, and have all the several GetCommand calls not actually traverse through the alias to the underlying command object The only times that an alias will be traversed are: a) execution; when time comes to run an alias, I will just grab the underlying command and options, and make the interpreter execute that according to its current algorithm b) subcommand traversal; if one has an alias to a multiword command, grabbing a subcommand will see through to the subcommand Other operations, e.g. command listing, command names, command helps, ..., will all use the alias directly. This will, in turn, lead to the removal of the separate alias dictionary, and just mix user commands and aliases in one map llvm-svn: 262986

The default help display now shows the alias collection by default, and hides commands whose named begin with an underscore. Help is primarily useful to those unfamiliar with LLDB and should aim to answer typical questions while still being able to provide more esoteric answers when required. To that latter end an argument to include the hidden commands in help has been added, and instead of having a help flag to show aliases there is now one to hide them. This final change might be controversial as it repurposes the -a shorthand as the opposite of its original meaning. The previous implementation of OutputFormattedHelpText was easily confused by embedded newlines. The new algorithm correctly breaks on the FIRST newline or LAST space/tab before the target column count rather than treating all whitespace interchangeably. Command interpreters now have the ability to specify help prologue text and a command prefix string. Neither are used in the current LLDB sources but are required to support REPL-like extensions where LLDB commands must be prefixed and additional help text is required to explain how to access traditional debugging commands. <rdar://problem/17751929> <rdar://problem/16953815> <rdar://problem/16953841> <rdar://problem/16930173> <rdar://problem/16879028> llvm-svn: 226068
