This contains 2 fixes for the details view
The first is that the padding in the scrolling view was causing the last frame to be clipped
The second is that we were uselessly displaying "(speedscope root)" in the stack trace view.
This also removes some sketch specific stuff from the keyed archive expanding code
Fixes#32
#33 added support for importing from instruments indirectly via opening instruments and using the deep copy command. This PR adds support for importing `.trace` files directly, though only for time profiles specifically, and only for the highest sample count thread in the profile.
This PR adds `.trace` files from Instruments 9, and adds support for importing from either Instruments 8 and 9. The only major difference in the file format seems to be that Instruments 9 applies raw `zlib` compression generously throughout the file.
This PR also adds example `.trace` files for memory allocations, which are not supported for direct import. They use a totally different storage format for recording memory allocations, and I haven't yet figured out how that list of allocations references their corresponding callstack.
Lastly, this PR also adds examples from Instruments 7 since I happen to have a machine with an old version of Instruments. Import from Instruments 7 probably wouldn't be hard to add, but I haven't done that in this PR.
This currently only works in Chrome, and only via drag-and-drop of the files.
To test, drag the decompressed `simple-time-profile.trace` from 6016d970b9/sample/profiles/Instruments/9.3.1/simple-time-profile.trace.zip onto speedscope.
The result should be this:
Fixes#15
This should help keep things organized as speedscope supports more languages & more formats
Test Plan: Try importing from every single file type, see that the link to load the example profile still works
This introduces a view for showing detailed information about a selected frame in the flamegraph. This provides information about self time & aggregate times across all instances of the function, regardless of where it is in the flamegraph.
This also shows a full stack with file & line information.
Fixes#20
On init, we check the hash fragment for these parameters and load the URL. We
always show a loading state in that case rather than the landing screen.
When determining the title, an explicitly-specified title takes precedence,
otherwise we use the filename.
I also added an error state, currently only used for my new code, but possibly
there could be a more robust or widespread error handling approach in the
future.
* Install prettier, set up the config file, and run it on all ts and tsx files.
* Install eslint and configure it with just eslint-plugin-prettier to check to
make sure that prettier has been run.
* Add a basic .travis.yml that runs eslint.
There are other style things that might be nice to enforce with ESLint/TSLint,
like using const, import order, etc, but this commit just focuses on prettier,
which gets most of the way there.
One annoying issue for now is that typescript-eslint-parser gives a big warning
message since they haven't updated to officially support TypeScript 2.8 yet. We
aren't even using any ESLint rules that need the parser, but if we don't include
it, ESLint will crash. TS2.8 support is hopefully coming really soon, though:

As for the prettier config specifically, see https://prettier.io/docs/en/options.html
for the available options.
Config settings that seem non-controversial:
Semicolons: You don't use semicolons. (I prefer semicolons, but either way is fine.)
Quote style: Looks like you consistently use single quotes outside JSX and double
quotes in JSX, which is the `singleQuote: true` option.
Config settings worth discussion:
Line width: You don't have a specific max. I put 100 since I think it's a good number
for people (like both of us, probably) who find 80 a bit cramped. (At Benchling we use
110.) Prettier has a big red warning box recommending 80, but I still prefer 100ish.
Bracket spacing: This is `{foo}` vs `{ foo }` for imports, exports, object literals,
and destructuring. Looks like you're inconsistent but lean toward spaces. I personally
really dislike bracket spacing (it feels inconsistent with arrays and function calls),
but I'm certainly fine with it and Prettier has it enabled by default, so I kept it
enabled.
Trailing comma style: Options are "no trailing commas", "trailing commas for
everything exception function calls and parameter lists", and "trailing commas
everywhere". TypeScript can handle trailing commas everywhere, so there isn't a
concern with tooling. You're inconsistent, and it looks like you tend to not have
trailing commas, but I think it's probably best to just have them everywhere, so I
enabled them.
JSX Brackets: You're inconsistent about this, I think. I'd prefer to just keep the
default and wrap the `>` to the next line.
Arrow function parens: I only found two cases of arrow functions with one param
(both `c => c.frame === frame`), and both omitted the parens, so I kept the
default of omitting parens. This makes it mildly more annoying to add a typescript
type or additional param, which is a possible reason for always requiring parens.
Everything else is non-configurable, although it's possible some places would be
better with a `// prettier-ignore` comment (but I usually try to avoid those).
Previously, I was doing a hacky release process where I had `index.html` serve contents for `jlfwong.github.io/speedscope`, but used `dev.html` locally. This seems like it broke with the latest parcel release, so I just revamped the release process instead.
Now, the `release.sh` script creates a temporary shallow clone of the repository, overwrites its contents with build artifacts, runs a local server to verify it's working, then commits and pushes to the `gh-pages` branches.
