RDiscount :generate_toc with Sinatra

由 强颜欢笑 提交于 2020-01-04 09:11:11
问题 So I have sinatra setup with Rdiscount to render a markdown file with a HAML layout. This all works but I want RDiscount to generate a table of contents based on the headers in my haml file. I've tried setting it in the sinatra configuration. set :markdown, :generate_toc => true but that doesn't seem to work. I've also tried doing it when I render the markdown like so: markdown :PAGENAMEHERE, :layout => :'layouts/PAGENAMEHERE', :generate_toc => true which also doesn't work. Is this even

Get tilt angle from the android accelerometer

由 ﹥＞﹥吖頭↗ 提交于 2020-01-03 08:34:19
问题 I have a class that implements SensorEventListener and I would like to get the tilt Angle of my device using the Accelerometer . I looked for examples on the internet but they use Sensor.TYPE_MAGNETIC_FIELD . I believe my device doesn't have this sensor because when I do the following check manager.getSensorList(Sensor.TYPE_ACCELEROMETER).size() , I get zero . Is there a way to get the tilt Angle by just using Sensor.TYPE_ACCELEROMETER values? 回答1: As people suggested you can use the

Documentation for creating custom Sprockets processors?

由 核能气质少年 提交于 2019-12-21 03:57:19
问题 I'm trying to create a sprockets preprocessor for Rails that finds .png.rb files in the asset pipeline and uses them to generate png screenshots of various pages in my application. I've read up on this topic quite a bit but I can't seem to find any straightforward documentation on how to get this set up. Help, please? Here's what I have so far: /initializers/sprockets.rb : require 'screenshot_preprocessor' Rails.application.assets.register_mime_type('screenshot/png', '.png.rb') Rails

How can i test tilt efftect? - IPhone Simulator

问题 I am trying to write a game. That game uses tilt effect, but i don't know how to test it on Iphone Simulator 3.0. I search it on internet, but the result is zero. How can i...? 回答1: Short answer: You can't, not directly. You have to use a real device. Longer answer: You could subclass UIAccelerometer and do as you like. You could simulate input, or write a client and server pair that sends acceleration information from a real device to your app running in the simulator, or from your Macbook's

Google static maps get satellite view with tilt

由 寵の児 提交于 2019-12-19 04:09:29
问题 Didn't see anything in documentation so I figured I'd ask here: For capturing image via google static maps api, is there any way to get views that have tilt? Doesn't seem to be any documentation on how to query for this. Thanks. 回答1: I've done a small example that could help you. It uses html2canvas.js and jquery.js I forked also what @mfirdaus did in another answer <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>Capture map</title> <style> html, body { height: 100%; margin: 0;

Middleman not parsing source file up template chain if missing ERb tags

由 我的梦境 提交于 2019-12-12 00:11:44
问题 I'm converting a Jekyll site to Middleman. I have named my files like filename.html.md.liquid.erb for processing with those libraries in that order: ERb, then liquid, then kramdown. What I found is that if I don't have at least one erb tag in the file, the template parsing simply stops and the whole file is rendered as plain text rather than being parsed by liquid and then kramdown. Simply adding <% if nil %> <% end %> at the bottom of the source document causes the whole template chain to be

Can anyone tell me whether gravity sensor is as a tilt sensor to improve heading accuracy?

由 给你一囗甜甜゛ 提交于 2019-12-11 18:55:06
问题 X and Y axis of magnetometer can be used to calculate the heading of north when phone is level to the local ground. But when rolling or pitching the phone, we should use roll and pitch degree to eliminate the tilt error. Now, I want to know whether the gravity sensor is used as tilt sensor to get the roll and pitch to help improve the accuracy of heading to the north? 回答1: Here I describe how to get the orientation of the device with respect to the horizontal plane and the magnetic North. It

Get Rotation (Tilt) Angle In Landscape View - Android Java

由 ⅰ亾dé卋堺 提交于 2019-12-11 06:48:12
问题 I've scrounged the web in search of a good example or someone trying to attempt the same thing, but so far I haven't had much luck. I am trying to get my Devices rotation angle (If you can imagine) starting at 180° (Flat). As the user tilts the device left and right, the angle adjusts accordingly. And as it rotates I want to simply update a TextView. I'm just lost as to what this evolves, some people suggest a gyroscope, accelerometer, even a magnometer, or a combination. I've gotten a few

Is there any workaround for disabling the “auto tilt when zooming” feature of the Google Earth plugin?

由 試著忘記壹切 提交于 2019-12-10 18:13:11
问题 Recent versions of Google Earth are shipping with a feature called "Auto tilt when zooming". If enabled, Google earth automatically tilts the camera towards the horizon as you zoom closer to the surface. This feature can be disabled from within the GUI (Preferences -> Navigation tab). Unfortunately, I have so far not found a way to disable it for the Google Earth plugin. Aseemingly the client setting corresponds to a registry key (HKCU\Software\Google\Google Earth Plus\SwoopEnabled). There

Android: Determining the angle of tilt using only accelerometers

由 ぃ、小莉子 提交于 2019-12-08 11:22:49
问题 I am trying to compute the angle of a leg instantaneously regarding an initial position using accelerometer readings. As I approached this, I decided I needed to record an averaged gravity vector and compute some angle between my current reading and that. Theoretically it seems plausible: the reading of gravity is different on each position of the leg, so in stationary positions the readings should converge to a vector I can use to find the angular displacement of the leg, with respect to the
