I tried a couple of different exercises and was getting the same error each time on initial test run. All are using c# with nunit:
'/nunit/NUnit.2.6.2/lib' in MONO_PATH doesn't exist or has wrong permissions.
Compilation failed: 1 error(s), 0 warnings
error CS0006: Metadata file `/nunit/NUnit.2.6.2/lib/nunit.framework.dll' could not be found
Makes it more colourful and also more similar to other dialog boxes.
Specifically, it needs moving into an avatar.run_tests() method which does everything, including the call to avatar.tested(...)
I don't do anything really fancy in jQuery but not staying up to date is almost always a bad idea.
When you run the app_controllers test you get this warning
/usr/lib/ruby/gems/2.3.0/gems/activesupport-4.1.0/lib/active_support/values/time_zone.rb:285: warning: circular argument reference - now
Upgrading to Rails 4.2.6 gets rid of the 'now' warning.
But it introduces deprecation warnings and breaks some of my routes...
Should be an easy job for someone with good rails knowledge.
Add a toggle syntax highlighting button to the options dialog
This can be accomplished by switching CodeMirror's theme to a "null" theme
Hi,
I had a link that I saved from a previous session from couple days ago (https://www.cyber-dojo.org/kata/edit/VEQ6v6R2bh?avatar=bear), and now when I click the link, I receive the following error:

How could I recover the previous session that I had?
Thanks
A test, which should otherwise pass, times out in the default Kotlin dojo session.

Function cyberDojo contains the word let, which isn't supported on Safari.
https://stackoverflow.com/questions/34636737/unexpected-use-of-reserved-word-let-in-strict-mode
The visible symptom is that if you visit http://cyber-dojo.org in Safari, the whole page loads, but none of the hyperlinks work. I click them, and nothing happens. (I assume this is because the Javascript that's supposed to hook them up to actions has not been run because of the above syntax error.)
Is it possible to use the word var instead of let (for example)?
Put instructions file in lower section with cyber-dojo.sh etc.
Put dot files at the bottom of the upper section (eg .jshintrc)
It should be handled (and tested) inside the runner_stateful service itself.
When this is done a bunch of the slowest web tests (app_controllers) can be deleted.
The test folder is ~45MB
Do not include this in the web image. Instead, mount it as a volume
when running the tests inside the web container.
This would bring the web image down to 230MB from 275MB.
This should make user's experience of hitting the test button faster.
This may help...

When typing in a filename the characters backslash and space are not allowed (space is allowed at the start and is ignored). That is, they appear on the filename but the [ok] button is disabled.
Would it be better if they were filtered out as they were pressed, viz they did not appear in the filename at all?
Note that text files can be created inside the container and round-trip back to the browser.
These files can have any legal Linux filename. Viz use any character except /
This means there is a difference between filenames you can use like this and filenames you can create directly in the browser.
Approval style tests are currently off-line because they require post-run .txt file retrieval.
See the cyber-dojo/languages-offline repo.
Now that runner is a separate service this would be a reasonable amount of work.
The direction: rtl in the CSS file at
Noticed while messing around with cyber-dojo/languages-start-points#5
if a lowercase a-f is entered display an uppercase A-F
This can be done in CSS

Make some smaller alpine-linux language images.
Specifically, C#-NUnit and Java-JUnit
Java
frolvlad/alpine-oraclejdk8:slim
How big is it? ~166.9 MB (vs 843.7 MB)
docker run --rm frolvlad/alpine-oraclejdk8:slim sh -c "javac -version"
javac 1.8.0_92
There is an alpine package called junit (branch=edge, repo=testing)
Put Alpine based small images into cyberdojo repo (rather than cyberdojofoundation) ?
Typically, when doing a longer dojo with a large group (eg in a themed tutorial day) the amount of progress the avatars make varies. It would be nice, periodically, to be able to 'converge' all the avatars to the files in a traffic-light carefully chosen from one of the avatars. Then get everyone to refresh their browsers and they would all be at the same point.
This is different to forking a new dojo (which you can already do). This means the files-set for the chosen traffic-light is sent to the storer as if each avatar had submitted it.
This feature feels like it would live on the diff, together with the fork/revert buttons.
If there's extra info, make the entries in the minor colum (eg "tests?") be links that display the info text in a popup box when hovered over.
If there's no extra info, then simply render them as plain text - no hover functionality.
If you append this line to cyber-dojo.sh
echo 'xxx' > small.file
and then press the [test] button
then small.file successfully round-trips back to the browser but...
o) its width-height appearance is very small.
o) it is resizeable! This is quite a find since I thought that was impossible!
o) it does not have line-numbers
Note this behaviour is not present on the live on cyber-dojo.org
You need to create a local server using the latest web service to replicate it.
The ability (in javascript) to do a simple search and replace on visible files.
Initially this can be very simple, with no regex, allowing a simple identifier renaming.
git 2.9+ has new --compaction-heuristic for improved diffs.
I would like to use this.
See https://github.com/JonJagger/differ
Alpine-linux has a package for 2.10+ (branch=edge, repo=main)
Git version in web image is 2.8.3
while you state that cyber-dojo is open source you don't mention under which license. (BSD? MIT? GPL 2? GPL 3?)
in my opinion, the license.md file on github should only mention the license for the code.
the license for using the server, should be on the server itself, and -- if i understand your purpose correctly -- does not matter for the people using your code or contributing to it.
the link to the usage terms of the server could be in the readme file, instead.
i can help you picking a license and publishing it, if you think you need more information on the topic.
keep up the great work!
Can we please import "certain third party" libraries in python cyber-dojo instance?
Either by:
We don't even need the fancy stuff like Tensorflow, Theano, scikit-learn, or ntlk. Just the very basic functionality creating vectors, etc. Python is not Python without Numpy and the other major libraries.
I know security can be issue, but we really need more basic libraries in order teach what makes python unique and better than other languages like java. This is why I suggested 3 possible solutions instead of just one.
This should be completely doable using CodeMirror calls.
The function needing work is cd.renameFile in
https://github.com/cyber-dojo/web/blob/master/app/assets/javascripts/cyber-dojo_files.js
http://cyber-dojo.org/review/show/24A724BD24?avatar=kingfisher&was_tag=4&now_tag=6
All I did was change the name from code.py to something else, and the double printing went away.
What gives?
After removing the sample feature file and step definitions, its tests are still executed. Maybe the .feature.cs files are not removed?
Example:
http://cyber-dojo.org/review/show/A80C07458B?avatar=bat&was_tag=8&now_tag=9
HikerSpec.feature and HikerSteps.cs are removed, but the output shows that the code generated from the HikerSpec.feature (ASimpleSpecificationToStartYouOffFeature) is still used and of course, failing.
At the moment they don't fold and hence you have to scroll to the right to read the whole line.
Ideally, the line-numbers will adjust accordingly as well. At the very least reduce font-size.
This should provide a noticeable speed improvement.
Currently when you click on the line-numbers column they toggle on/off.
Remove that.
Instead add a line-number toggle to the options dialog (only on kata/edit page).
On the kata/edit page if you select a file from the filelist, eg cyber-dojo.sh, using the mouse cursor, then it gets set to the correct 'selected' colour.
If you then move away from that file using the Alt-K hotkey, the instructions filename does not get set back to the 'unselected' colour.
Update: After Alt-K the hand-cursor is invisible until you move the cursor again, at which point the CSS colour goes back to normal. The CSS that does this is
&:hover { color: lighten($darker-color, 60); }
in app/assets/stylesheets/wide-list-item.scss
Decided to simplify things by removing that fragment of CSS.
Currently, the download button from the dashboard page gives you a tgz file which untars to a set of manifest.json files, one per avatar+traffic-light. This is the format used in the storer service and so is useful for admins moving dojos from one server to another.
A more useful format for the avatars would be to download a tgz file which untars to a set of git repositories, one per avatar. Add a second download button for this.
The app_controller tests are issuing a warning
WARN: tilt autoloading 'sass' in a non thread-safe way; explicit require 'sass' suggested.
How to fix this?
If cyber-dojo.sh does this
touch empty.file
Then this is not round-tripping back to the browser.
This is because @new_files is [] in kata_controller.rb
Similarly if instructions is an existing file and cyber-dojo.sh does this
rm instructions
touch instructions
Then again, instructions is not round-tripped back to the browser.
the up.sh script does this
$ cyber-dojo down
$ cyber-dojo up
This assumes the cyber-dojo script is on the path and it might not be.
Also, if you are running this on a host which has customized the default start-points then the customed start-points will be loaded. One possible fix is to...
o) create 3 customized start points from the 3 github repos and use uuidgen to name them (git pulls will require network access)
o) replace [cyber-dojo up] with [cyber-dojo up --languages=X1 --exercises=X2 --custom=X3]
where X1,X2,X3 are the uuidgen'd names.
o) when the tests finish do [cyber-dojo start-point rm] on each of X1,X2,X3
new-files and deleted-files are round-tripped back to the browser. But changed-files are not.
For example, ruby-minitest has simple statement coverage which creates a file coverage/.last_run.json
This file is not updated in the browser and so always contains the results of the first test run.
It looks like the width of the cursor is too thin...
It seems to be ok on Firefox, Safari, Opera but I have not done a lot of exploratory testing.
app/view/kata/_visible_files.html.erb handles the filename called output specially.
And so does app/controller/kata_controller.rb
It would probably simplify the code if output was treated as just another file, possibly with a touch of javascript to control attributes such as the textarea wrap.
Is support for markdown format envisioned?
If you add the following lines to cyber-dojo.sh
touch empty.file
Then you do not get an empty file back in the browser.
Make web's call to saver.kata_ran_tests() async/fire-and-forget.
Maybe using http://unirest.io/ruby.html ?
Also, if saver raises an exception don't let it stop runner's results from getting back to the browser.
BDD style frameworks, for example, want to have a certain directory structure involving a directory called feature.
At the moment an avatars files are all in a single directory.
cd.toggleSyntaxHighlight = () => { ... };
is at the top of /app/assets/javascript/cyber-dojo_codemirror.js
This uses two helper functions disableSyntaxHighlight and enableSyntaxHighlight.
So enableSyntaxHighlight needs to be run when a new/rename file operation takes place, as long as syntaxHighlightEnabled() is true
Add the display_name, exercise_name to the dashboard on the LHS.
Use the same format as the options dialog (from the footer bar).
Useful if you have several language sessions going at the same time.
I think the underlying [docker pull] is taking longer than a default timeout.
Particularly when pulling a non Alpine image. If you wait a while and do a [docker images] on the server then the image has been pulled, and if you do another identical setup its fine.
