This is my first day trying to use slidify.
Just wondering if the slidy option for framework should work?
I am able to generate slides using each of the other options in brackets {io2012, html5slides, shower, dzslides} however with slidy as the option, the index.html generated file has a size of 0.
---
title : Testing
framework : slidy # {io2012, html5slides, shower, dzslides, ...}
highlighter : highlight.js # {highlight.js, prettify, highlight}
hitheme : tomorrow #
widgets : [] # {mathjax, quiz, bootstrap}
mode : selfcontained # {standalone, draft}
---
(I am using an extract of the R markdown code linked to from: http://lamages.blogspot.com.au/2013/05/interactive-presentation-with-slidify.html)

We are using gradle.plugin.org.detoeuf:swagger-codegen-plugin.
We want to change the content of the build.gradle file in the output directory.
We added the gradle.build file to the .swagger-codegen-ignore but BOTH .swagger-codegen-ignore file and gradle.build file are re-created every time we call the swagger task.
Our swagger section looks like this
swagger {
inputSpec = "${project.projectDir}/swagger/backoffice-service-api-swagger.json"
outputDir = file("${project.projectDir}/../backoffice-service-api-client/")
lang = 'java'
additionalProperties = [
'invokerPackage' : 'com.aaa.bbb.backoffice.service',
'modelPackage' : 'com.aaa.bbb.backoffice.service.model',
'apiPackage' : 'com.aaa.bbb.backoffice.service.api',
'dateLibrary' : 'joda',
'groupId' : 'com.aaa.bbb',
'artifactId' : 'backoffice-service-api-client',
'artifactVersion' : '1.0.0',
'hideGenerationTimestamp': 'true',
'dateLibrary' : 'java8'
]
systemProperties = ["apiTests" : "false"]
}
.swagger-codegen-ignore file looks like this -
# Swagger Codegen Ignore
# Generated by swagger-codegen https://github.com/swagger-api/swagger-codegen
# Use this file to prevent files from being overwritten by the generator.
# The patterns follow closely to .gitignore or .dockerignore.
# As an example, the C# client generator defines ApiClient.cs.
# You can make changes and tell Swagger Codgen to ignore just this file by uncommenting the following line:
#ApiClient.cs
# You can match any string of characters against a directory, file or extension with a single asterisk (*):
#foo/*/qux
# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
#foo/**/qux
# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
# You can also negate patterns with an exclamation (!).
# For example, you can ignore all files in a docs folder with the file extension .md:
#docs/*.md
# Then explicitly reverse the ignore rule for a single file:
#!docs/README.md
build.gradle
You can add ignoreFileOverride option in additionalProperties as below. The files provided in ignoreFileOverride option do not exists in project, then swagger-codegen will generate them and if files exist in project then swagger-codegen will ignore them.
swagger {
inputSpec = "${project.projectDir}/swagger/backoffice-service-api-swagger.json"
outputDir = file("${project.projectDir}/../backoffice-service-api-client/")
lang = 'java'
additionalProperties = [
'invokerPackage' : 'com.aaa.bbb.backoffice.service',
'modelPackage' : 'com.aaa.bbb.backoffice.service.model',
'apiPackage' : 'com.aaa.bbb.backoffice.service.api',
'dateLibrary' : 'joda',
'groupId' : 'com.aaa.bbb',
'artifactId' : 'backoffice-service-api-client',
'artifactVersion' : '1.0.0',
'hideGenerationTimestamp': 'true',
'dateLibrary' : 'java8',
'ignoreFileOverride' : '.swagger-codegen-ignore,build.gradle'
]
systemProperties = ["apiTests" : "false"]
}
Is there a way to do 'hot code reloading' with a Rails application in the development environment?
For example: I'm working on a Rails application, I add a few lines of css in a stylesheet, I look at the browser to see the modified styling. As of right now I have to refresh the page with cmd-r or by clicking the refresh button.
Is there a way to get the page to reload automatically when changes are made?
This works nicely in the Phoenix web framework (and I'm sure Phoenix isn't the only framework in this feature). How could a feature like this be enabled in Ruby on Rails?
I am using this setup reloads all assets, js, css, ruby files
in Gemfile
group :development, :test do
gem 'guard-livereload', '~> 2.5', require: false
end
group :development do
gem 'listen'
gem 'guard'
gem 'guard-zeus'
gem 'rack-livereload'
end
insert this in your development.rb
config.middleware.insert_after ActionDispatch::Static, Rack::LiveReload
i have this in my guard file
# A sample Guardfile
# More info at https://github.com/guard/guard#readme
## Uncomment and set this to only include directories you want to watch
# directories %w(app lib config test spec features) \
# .select{|d| Dir.exists?(d) ? d : UI.warning("Directory #{d} does not exist")}
## Note: if you are using the `directories` clause above and you are not
## watching the project directory ('.'), then you will want to move
## the Guardfile to a watched dir and symlink it back, e.g.
#
# $ mkdir config
# $ mv Guardfile config/
# $ ln -s config/Guardfile .
#
# and, you'll have to watch "config/Guardfile" instead of "Guardfile"
guard 'livereload' do

end
I am using zeus instead of spring on this setup.
Run guard
Open localhost:3000 and you are good to go.
This should resolve your question, and have blazing reload times better than browserify.
I commented out guard looking at test directories if you want you can uncomment those lines if your are doing TDD.
CSS hot swapping and auto-reload when HTML/JS changes can be achieved with guard in combination with livereload: https://github.com/guard/guard-livereload
This gem would auto reload when you make changes to js elements(Not css or ruby files).
https://github.com/rmosolgo/react-rails-hot-loader
Never seen css hot code reloading in rails platform.
i am trying to compile my small project (a yesod application with lambdacms) on nixos. However, after using cabal2nix (more precisely cabal2nix project-karma.cabal --sha256=0 --shell > shell.nix) , I am still missing a dependency wrt. postgresql it seems.

I assume not much is missing, so a pointer would be nice.
What is also weird, that is that "nix-shell" works but following that up with "stack exec yesod devel" tells me

setup-Simple-Cabal-1.22.4.0-x86_64-linux-ghc-7.10.2: The program 'pkg-config'
version >=0.9.0 is required but it could not be found.
After adding pkgconfig to my global configuration, the build seems to get a little further ahead, so it seems that shell.nix is ignored somewhat.
(Sources for what I tried so far:
https://groups.google.com/forum/#!topic/haskell-stack/_ZBh01VP_fo)
Update: It seems like I overlooked this section of the manual
http://nixos.org/nixpkgs/manual/#using-stack-together-with-nix
However, the first idea that came to mind
(stack --extra-lib-dirs=/nix/store/c6qy7n5wdwl164lnzha7vpc3av9yhnga-postgresql-libpq-0.9.1.1/lib build)
did not work yet, most likely I need to use
--extra-include-dirs or try one of the variations. It seems weird that stack is still trying to build postgresql-libpq in the very same version, though.
Update2: Currently trying out "stack --extra-lib-dirs=/nix/store/1xf77x47d0m23nbda0azvkvj8w8y77c7-postgresql-9.4.5/lib --extra-include-dirs=/nix/store/1xf77x47d0m23nbda0azvkvj8w8y77c7-postgresql-9.4.5/include build" which looks promising. Does not look like the nix-way, but still.
Update3: Still getting
<command line>: can't load .so/.DLL for: /home/markus /.stack/snapshots/x86_64-linux/nightly-2015-11-17/7.10.2/lib/x86_64-linux- ghc-7.10.2/postgresql-libpq-0.9.1.1-ABGs5p1J8FbEwi6uvHaiV6/libHSpostgresql-libpq-0.9.1.1-ABGs5p1J8FbEwi6uvHaiV6-ghc7.10.2.so
(libpq.so.5: cannot open shared object file: No such file or directory) stack build 186.99s user 2.93s system 109% cpu 2:52.76 total
which is strange since libpq.so.5 is contained in /nix/store/1xf77x47d0m23nbda0azvkvj8w8y77c7-postgresql-9.4.5/lib.
An additional
$LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/nix/store/1xf77x47d0m23nbda0azvkvj8w8y77c7-postgresql-9.4.5/lib
does not help either.
Update4:
By the way, yesod devel does the same as stack exec yesod devel. My libraries are downloaded to /nix/store but they are not recognized.
Maybe I need to make "build-nix" work and yesod devel does not work here?
Just for completeness, here is stack.yaml
resolver: nightly-2015-11-17
#run stack setup otherwise!!
# Local packages, usually specified by relative directory name
packages:
- '.'
# Packages to be pulled from upstream that are not in the resolver (e.g., acme-missiles-0.3)
extra-deps: [lambdacms-core-0.3.0.2 , friendly-time-0.4, lists-0.4.2, list-extras-0.4.1.4 ]
# Override default flag values for local packages and extra-deps
flags:
karma:
library-only: false
dev: false
# Extra package databases containing global packages
extra-package-dbs: []
Next weekend, I will check out
https://pr06lefs.wordpress.com/2014/09/27/compiling-a-yesod-project-on-nixos/
and other search results.
Funny, because I've just had a similar problem myself - solved it by adding these two lines to stack.yaml:
extra-include-dirs: [/nix/store/jrdvjvf0w9nclw7b4k0pdfkljw78ijgk-postgresql-9.4.5/include/]
extra-lib-dirs: [/nix/store/jrdvjvf0w9nclw7b4k0pdfkljw78ijgk-postgresql-9.4.5/lib/]
You may want to check first which postgresql's path from the /nix/store you should use with include/ and lib/:
nix-build --no-out-link "<nixpkgs>" -A postgresql
And BTW, why do you use nix-shell if you are going to use stack and you have project-karma.cabal available..? Have you considered migrating your project with stack init..?
Looks like stack is trying to build haskellPackages.postgresql-libpq outside of the nix framework.
You probably don't want that to happen. Maybe try to add postgresql-libpq to libraryHaskellDepends?
According to pandoc(1), pandoc supports internal links in HTML slides. But nothing happens for me when I click one.
A minimal example:
% A minimal example
% moi
% 2015-04-04
# Section 1
la la la
# Section 2
cf. [Section 1](#section-1)
I save the foregoing as example.md. Then in bash I run
file=example && \
pandoc -fmarkdown -tslidy --standalone --self-contained -o$file.html $file.md
Having opened the resulting HTML slides in a web browser, I click "Section 1" on slide "Section 2", but nothing happens. This I have tried in multiple browsers on multiple devices: xombrero on a Macbook running Arch Linux, Chrome on a Moto X running Android and Chrome on a Sony laptop running Windows 8.1. The results are the same. I am using pandoc version 1.13.2.
The link produced by pandoc for the internal reference is different from the link of the relevant slide: in the present example, the former ends in #section-1 and, the latter, in #(2). I suppose that this is why clicking the internal link does not return to the relevant slide. Is there some way to achieve that internal links do go to their relevant slides?
Here's the relevant HTML:
<body>
<div class="slide titlepage">
<h1 class="title">A minimal example</h1>
<p class="author">
moi
</p>
<p class="date">2015-04-04</p>
</div>
<div id="section-1" class="slide section level1">
<h1>Section 1</h1>
<p>la la la</p>
</div>
<div id="section-2" class="slide section level1">
<h1>Section 2</h1>
<p>cf. Section 1</p>
</div>
</body>
Thanks for any help!
Your problem is not with Pandoc but with Slidy. Pandoc is creating the right HTML for an ordinary HTML page but the Slidy slide software does not support going to a <div> - only going to a slide number.
If you change your link to cf. [Section 1](#(2)) ('2' being the number of the slide with 'Section 1') then it will work fine.
BTW - It works perfectly in a reveal.js slideshow created by Pandoc.
Although the question is stated more than five years ago, I recently had the same problem and created a postprocessing script in Python, which works for me. Essentially it is reading the Pandoc -> Slidy html output, scanning for internal links and replacing them with the slide number on which the link id is defined.
def Fix_Internal_Slidy_Links(infilename, outfilename):
"""Replaces all internal link targets with targets of the respective slidy page number
"""
page_pattern = ' class=\"slide';
id_pattern = ' id=\"';
internal_link_pattern = '<a href=\"#';
id_dict = dict();
whole_text = [];
cur_page = 0;
#
# First read all ids and associate them with the current page in id_dict
with open(infilename, 'r', encoding='utf-8') as filecontent:
for idx_cur_line, cur_line in enumerate(filecontent):
whole_text += [cur_line];
if (page_pattern in cur_line):
cur_page += 1;
#
if (id_pattern in cur_line):
while (id_pattern in cur_line):
startidx = cur_line.index(id_pattern);
cur_line = cur_line[startidx+len(id_pattern):];
lineparts = cur_line.split('"');
# Check if the current id is properly ended
if (len(lineparts) > 1):
id_dict.update([(lineparts[0], cur_page)]);
#
# Then process the code again and replace all internal links known in id_dict
with open(outfilename, 'w', encoding='utf-8') as filecontent:
for cur_line in whole_text:
if (internal_link_pattern in cur_line):
temp_line = '';
offset = 0;
while (internal_link_pattern in cur_line):
startidx = cur_line.index(internal_link_pattern);
# Extract name
temp_line += cur_line[offset:startidx+len(internal_link_pattern)];
cur_line = cur_line[startidx+len(internal_link_pattern):];
lineparts = cur_line.split('"');
if (len(lineparts) < 2):
# It seems that the id is not properly finished
break;
#
link = lineparts[0];
try:
# Create a link to the page assigned to that id
replacement_link = '(' + str(id_dict[link]) + ')"';
except:
# The link reference is not known in id_dict so do not change it
replacement_link = lineparts[0] + '"';
#
temp_line += replacement_link;
cur_line = cur_line[len(lineparts[0])+1:];
#
cur_line = temp_line + cur_line;
#
filecontent.write(cur_line);

I'm working on a Rmd document that I would like to compile to html using knitr package via the HTML export mechanism available in RStudio. The problem can be reproduced with the code below:
Example
# Set up
rm(list = ls())
data(airquality)
attach(airquality)
packs <- c("randomForest", "knitr", "xtable", "xtable", "stargazer")
lapply(packs, require, character.only=T, quietly = TRUE, warn.conflicts = FALSE)
# Model
airquality <- na.roughfix(airquality)
dummy <- randomForest(Ozone ~., data = airquality)
# Problem
kable(dummy)
xtable(dummy)
stargazer(dummy)
The issue is further illustrated by the output below:
Output
> # Problem
> kable(dummy)
Error in as.data.frame.default(x) :
cannot coerce class "c("randomForest.formula", "randomForest")" to a data.frame
> xtable(dummy)
Error in UseMethod("xtable") :
no applicable method for 'xtable' applied to an object of class "c('randomForest.formula', 'randomForest')"
> stargazer(dummy)
% Error: Unrecognized object type.
Is it possible to force the randomForest output into a nice html table that would be presentable in a markdown document?
