* Indexing and search improvements
** (1) Move to a line-based search, as proposed in https://github.com/mozilla/dxr/pull/161#issuecomment-25201532.
** (3) Stop differentiating between macros, functions, consts, etc.: just find me an *anything* called "fred". People coming up to the Innovation Fair booth were confused that they had to know the kind of target.
** (3) Just typing a filename (or path segment?) without a path: specifier should find files by name or path.
*** [Should be solved by ^^] Trying to find files is hard. (Still haven't figured out how to get easily from the main page to Navigator.cpp on dom/base)
*** [Should be solved by ^^] A basic "file:" keyword hint with simple wildcard globing could do most of it well enough, I think... "file:*.css", "file:nsILogin*", "file:/test*". (We already search for "path" matches as unanchored substrings. We just need to add the globbing. Why this isn't super slow I don't know.)
*** [Should be solved by ^^] As a jump point when I know a filename (eg, "nsILogin", click search, click the particular IDL I wanted).
*** Oddly enough, the direct result finder does search for paths ending in whatever you type, so that's an inconsistency (noticed by jmaher).

* Advanced search and textual search should either be mutually exclusively shown (in which case we'd act like Google's advanced search, snapping back to textual mode when showing results), or we can have server-side code send back the textual equivalent to the advanced search (or the advanced equivalent to the textual search) along with the search results. That way, we don't immediately need to write a JS query parser, though we could add one later and get better latency. We'll have examples of what each advanced field takes in dimmed text in the field, demonstrating a few of the interesting features: for instance, '"main(const int, ...)"'.

Now that we've landed the UI branch, the remaining items have migrated to the [[DXR Roadmap]].

* (1) Index multiple trees (starting with comm-central and mozilla-aurora, the most commonly used ones on MXR. The UX branch has been requested, too.) (some impact from IT, possibly) - this is a blocker for turning off MXR

* (1) Move to a line-based search, as proposed in https://github.com/mozilla/dxr/pull/161#issuecomment-25201532.

** [Should be solved by ^^] As a jump point when I know a filename (eg, "nsILogin", click search, click the particular IDL I wanted).
* (3) Better ranking: if you type an exact identifier name, put the definition at the top. (If we implement "id:", this is easy.)
* (3) Stop differentiating between macros, functions, consts, etc.: just find me an *anything* called "fred". People coming up to the booth were confused that they had to know the kind of target.
* (4) Search just within strings, for error messages and such.
* (4) Let us structurally query stuff that gets #ifdef'd out on x86, like ARM stuff.
=== Indexing ===
* (3) Better support for JS, Python, etc.
** Remove the C++ assumptions from the core so we can support structured queries on other languages. Python keeps coming up. Java and Scala did once as well. People mentioned JS a long time ago.
* (4) Merge multiple build configuration databases somehow.
** The code base is compiled for multiple platforms. Currently I cannot find the functions which are defined on ARM unless we use a search as we used to do on MXR.
* (4) Include Doxygen/Javadocs-like documentation. For C, C++, IDL, Java, JS, etc.
* (5) Support for generated files in indexing. (Is this about IDLs, for example? We should just make DXR understand IDLs. Here's the code that turns IDL attr names into C++ and JS ones: http://dxr.mozilla.org/mozilla-central/source/xpcom/idl-parser/header.py#l34, http://dxr.mozilla.org/mozilla-central/source/dom/bindings/Codegen.py (search for "binaryNames and makeNativeName").)


=== Blame/VCS integration ===

* (4) Diff between trees
* (4 - Does MXR offer this now? ''yes -MattN'' I see it only in MXR's links through to hgweb. Does it offer it internally as well?) Be able to refer to specific revisions of code somehow, so links don't rot.
* <strike>(4) Show hash or other VCS revision identifier, perhaps with the "Built 6 days ago" indicator. (easy)</strike>
* <strike>(4) Show hash or other VCS revision identifier, perhaps with the "Built 6 days ago" indicator. (easy)</strike>
* (4) Blame link should preserve the line-number fragment so it hops right to the highlighted line in hgweb or whatever.
* (4) Be able to refer to certain ranges of code.
* (5 - Shouldn't we delegate to hgweb or github for this?) Blame integrated into main file view
** Be able to navigate blame history better, stepping back and back in time until we find the change we were looking for.
=== Other ===
* (4) Support for image browsing would be super helpful for front-end stuff.
* Compare http://dxr.mozilla.org/mozilla-central/source/toolkit/themes/windows/global/icons with http://mxr.mozilla.org/mozilla-central/source/toolkit/themes/windows/global/icons/
* (5) DXR gives a nice contextual navigation, but the size of the code base is overwhelming to have a clear understanding of what is going on. One of the thing that I am looking at in general is to understand the conditionals which are giving a particular result, or the consequences of a statement. Such overview is hard to get when you have ~30 DXR tabs opened. I would love to have a graph overview of these relations, as well as seeing the conditionals/guards as part of the graph.
* (huh?) "cycleCollection" on the right side may or may not do something useful. In most cases it just ignores all the stuff, so it might be better to not have it at all.

* (2) Mook (and Dave Townsend) switches trees a lot while looking at a single file in MXR. He'd like to be able to do that without losing his scroll position, as it typically lands him at a similar-enough place in the code that he can reorient himself. We'll add a tree switcher to the navigation panel, which appears when a file is being viewed. The nav panel will be pinned.
* <strike>(2) When navigating down the directory/file tree, it keeps autofocusing the search field, which is super-annoying if you're using keyboard-only navigation (with quickfind and enter) to do the traversal.</strike>

* (3) Enable integration with IDEs. I'm scoping to not include writing any plugins, but we should at least expose a well-documented public API. Then we can see what develops. We've had interest from a couple directions on this.

* (4) Count of search results, so we can use DXR to gather continuous metrics
* (4) Direct results: some love them, some hate them (because they just want to see the file pathname (don't we show that with the file? Is it bothersome because it's slow to load?))
* (4) Show context around results (with a clickable control? by saying "context:3[lines]" in the query? show the entire statement?)
* (4) Currently, you always get the context menu. But I (erikrose) suspect there is a by-far-most-common case: jumping to a symbol's definition. If we were to map that to a normal click and save the context menu for context-clicks (right-clicks, etc.), it would let people bounce around the codebase faster. It would be great to back up my supposition with some measurements. Risk: This makes the existence of the context menu (and thus a lot of DXR's capabilities) non-obvious.

* (1) Clicking on macros seem to lead to some results, but definitely not the one I'd expect - the definition of the macro.
* <strike>(3) Fix redundant "mozilla-central/search?tree=mozilla-central"</strike>
* <strike>(3) Fix redundant "mozilla-central/search?tree=mozilla-central"</strike>
* (4) I find the call graph information to be wrong some of the time, I have never been able to tell why. See this query for example: http://dxr.mozilla.org/mozilla-central/search?q=%2Bcallers%3A%22mozilla%3A%3AAudioNodeStream%3A%3ASetDoubleParameter%28uint32_t%2C+double%29%22. Do you have any idea what the source of these problems is, and if yes, is that on track to get fixed?
