widgets.jl

Buttons are unresponsive, don't know if that is intentional.

Better package name?

@shashi @aviks As we discussed before, Canvas invokes many different meanings in one's mind. I liked @shashi 's suggestion of calling this package Escher.jl.

Is 0.4 supported?

I just tried setting up Escher, but the server failed to load. Do you want help tracking down issues for 0.4? My julia version is about a week behind master right now.

Would this be a good candidate for inclusion in JuliaWeb?

If you think it's appropriate, I'd be happy to help transfer it (and make you a contributor, of course). Let me know. This looks like an absolutely wonderful package.

Broken example in docs/index.jl

I'm trying to go through the tutorial on escher-jl.org, but I keep running into examples that won't run. I'm currently having trouble with Pattern 2, Example 1. At first, it wouldn't work because it couldn't find pad, which is in Compose (which is not imported in the text of the example). Even with the added using, it still presents an error message -- one that I'm not sure how to resolve.

Code with added using:

using Compose

function main(window)
    push!(window.assets, "tex")

    txt = tex("T = 2\\pi\\sqrt{L\\over g}")
    txt1 = fontcolor("#499", txt)
    txt2 = pad(5mm, txt1)
    txt3 = fillcolor("#eeb", txt2)

    vbox(txt, txt1, txt2, txt3)
end

Examples fail on tagged version of Escher

When I've just Pkg.add("Escher") and Pkg.checkout("Mux"), none of the examples work. Example errors from minesweeper are below. However, minesweeper does work if I Pkg.checkout("Escher"), so maybe you could tag a new version?

It is really frustrating to add a new package, follow the instructions to run an example, and literally spend an hour encountering and overcoming errors before even one example runs successfully. (...especially when all of the error seem to just be due to packages not being tagged.) Is there any test process setup for Escher to let you know if the currently tagged version "Just Works" on the examples, when installing on a fresh Julia instance with just Pkg.add("Escher")? Because I think that might help prevent this situation in the future.

In the terminal:

Documentation

While I want to write all of this out myself, my hands don't seem to like the idea so much. Here is a table of contents of the things I want to document. Any help with documentation will be hugely appreciated!

Take a look at docs/index.jl, docs/layout.jl, docs/reactive.jl, docs/layout-api.jl to see how documentation can be written.

Electron backend

I wonder if it is possible to have an Electron backend, as an alternative to the Polymer backend. Perhaps that will also make it possible to build rich desktop apps.

latex.html missing?

Can't access a local svg image

I've tried to add an svg in different ways but I can't find I way to make it display. For instance,

Elem{:object, :object}({:data=>"image.svg", :type=>"image/svg+xml"}, EmptyNode)

Elem{:img, :img}({:src=>"image.svg"}, EmptyNode)

do not work

Broken examples

As of now, from tests using Julia v0.3.11 on Chromium:

examples/minesweeper.jl

nothing happens when you click on a square

examples/plotting.jl

``|> has no method matching |>(::Plot, ::ComposeGraphic)

This can be circumvented by unchaining the drawing of plot_beta.

examples/latex.jl

Rendered text does not update

docs/index.jl

HTML links broken if served

docs/layout2-api.jl

References functions that are currently commented out (dropdown, item?)

Version of Julia in the README

The use of Markdown.jl suggests that this is best run with Julia 0.3. It would be nice to mention that in the README, since one cannot yet install Canvas.jl as a package.

I did checkout the latest as well using Pkg.checkout("Escher")

Escher and websockets

When you refresh a page from chrome it appears that Escher/Mux does not always notice the close of the websocket. Since the socket is keyed by the file name when next Escher tries to write to the socket it is in a closed state. This causes the process to bomb out, the symptom being an error from Reactive 'push! called when another signal is still updating'

Any thoughts how to resolve / chase down?

rfc: use a native webview like Electron

This means users don't need to open a browser separately to the server. I've got this working with Patchwork.jl and thought you might already be considering doing it with Escher.jl so here is a link to that project if you want a starting point. Sorry for the noise if you weren't considering it.

[PkgEval] Escher may have a testing issue on Julia 0.3 (2015-05-26)

PackageEvaluator.jl is a script that runs nightly. It attempts to load all Julia packages and run their tests (if available) on both the stable version of Julia (0.3) and the nightly build of the unstable version (0.4). The results of this script are used to generate a package listing enhanced with testing results.

On Julia 0.3

On 2015-05-26 the testing status was N/A - new package.
On 2015-05-26 the testing status changed to Package doesn't load.

Package doesn't load. means that PackageEvaluator did not find tests for your package. Additionally, trying to load your package with using failed.

This issue was filed because your testing status became worse. No additional issues will be filed if your package remains in this state, and no issue will be filed if it improves. If you'd like to opt-out of these status-change messages, reply to this message saying you'd like to and @IainNZ will add an exception. If you'd like to discuss PackageEvaluator.jl please file an issue at the repository. For example, your package may be untestable on the test machine due to a dependency - an exception can be added.

Freezing on include(Pkg.dir("Escher", "src", "cli", "serve.jl")) and escher --serve to API macro's use of `=>` is broken on Julia v0.4

I've been following the installation / usage instructions for Escher here: https://shashi.github.io/Escher.jl/ and am running into a problem on Version 0.4.0-dev+6112 (2015-07-20 17:52 UTC) Commit 189a043 (3 days old master):

Pages from `escher --serve` appear blank

I'm trying out Escher for the first time. I've just installed the latest julia 0.4 nightly and have updated all my packages (as of 6 Sept 2015). When I try to serve up any of the examples, I just get a blank page in the browser (tested using Chrome and Safari). Selecting "View Source" from the browser clearly shows some HTML with a lot of Javascript code, but I never see a webpage.

$ escher --serve layout.jl 

lots of deprecation warnings....

Listening on 0.0.0.0:5555...

What am I doing wrong?

0.4 deprecations break functionality in Escher

Make length measures play nicely with Compose

If I change the plot command in plot.jl to the following

plot([x -> sin(x + phase), x -> cos(x + phase)], 0, 6, 
                xintercept=[-.55, +.5], Geom.vline(color="purple", size=0.2mm))

I get the following error on the console:

Specify a base directory

Currently, canvasd only serves .jl files out of its current working directory.

There should be of specifying a base directory from which to serve files. Forward relative paths from this directory should be followed. Backward relative paths should not be allowed.

It may be worth thinking about a long term configuration format. Command line flags only? INI/Toml files? JSON?

Better asset loading

Right now, all assets are loaded from Escher's assets folder, uncompressed and un-concatenated. This is of course not ideal.

Here is a rough sketch of what this could look like in the future:

push!(window.assets, ["a.html", "b.css, "c.js"])

a, b, and c would get concatenated and gzipped (the first time they are needed), and cached in a file under assets/cache with some canonical name like

string(join(sort(["a.html", "b.css", "c.js"]), "+")  |> hash) * ".html.gz"

Problem 1: Some polymer files are repeatedly included in others. So if window.assets is pushed to a second time, it should be possible to exclude what was already sent. And the corresponding statements must be stripped. This is not only nice to have, not having this is a fatal error since elements will try to register themselves more than once.

Problem 2: cache invalidation. If one is editing the assets file, when should they be cleared? a manual way to do it can be provided: escher --clear-cache.

Blank output

So, doing everything mentioned in #3 removes all error messages. However, then navigating to, for eg. http://localhost:8000/examples/toolbar.jl shows a blank page in the browser.

View source in the browser shows: https://gist.github.com/aviks/16e883c1ac50662a5a02

Resources fetched in the browser as follows:

So what can I do to troubleshoot this further?

PS: did I say it already... hugely excited about Canvas.jl!!

pages confuses layout

function main(window)
    push!(window.assets,"layout2")
    A = vbox(md"Hello, world!"|>
             fontcolor("#FFFFFF")|>
             pad(1em)|>
             fillcolor("#006699"),
             md"Howdy!"|>
             fontcolor("#FFFFFF")|>
             pad(1em)|>
             fillcolor("#669933")
             )
end

does what I expect it to do. There are two boxes on top of each other, a blue one which says, "Hello, world!" and a green one which says "Howdy!"

However, say you want to make this layout the first page of a set of pages:

function main(window)
    push!(window.assets,"layout2")
    A = vbox(md"Hello, world!"|>
             pad(1em)|>
             fillcolor("#006699"),
             md"Howdy!"|>
             pad(1em)|>
             fillcolor("#669933")
             )
    pages([A])
end

This collapses the boxes and puts them on top of each other. The text ends up hanging outside the boxes.

Maybe I'm not understanding something about how pages works, but it seems like you should be able to use the layout API on individual pages.

Let me know if I can fix something easily, or if we just need more docs about higher-order layouts.

Daisy Chaining Inputs from one Widget to Another

Shashi,

Is there currently a way to a daisy chain signals from one widget to another?

That is: if I have an Input into one widget, that itself creates an input used by another widget.

Getting error messages about: push! called when another signal is still updating

It looks like there was a reference to something like this in an issue raised by @Keno on JuliaGizmos/Reactive.jl#62.

Any suggestions here or workarounds?

Thanks,
Michael

segmentation fault

Hi! When I try to run and access an example of escher.jl , I have a problem of segment fault...Does anyone know why?

website has no title tag

In the browser tab, it shows up as the page URL, "http://escher-jl.org/".

Btw, a favicon would be nice too.

Dynamic layouts

@shashi : I was wondering if there are any example of truly dynamic layouts?

For example, do you have an example of some callback that would add a new tab?

In a further step down this road, do you have any thoughts on how to integrate something like a gridstack-like drag/drop capability: http://troolee.github.io/gridstack.js/

In that case, not sure if julia would owns the layout model.

(BTW I see that polymer has some core-drag-drop capability, but the dynamic layout from gridstack is a bit more interesting - https://www.polymer-project.org/0.5/docs/elements/core-drag-drop.html)

Thanks,
Michael

Docs

Trying to experiment with using Escher for building a data dashboard. Would love some docs. Conversely, if you need a bit of help with building the docs itself, I can fork the repo and work on a gh-pages branch.

Input field initialization fails, causing empty signal from forms.

Given the following watch! definition, where s is a sample().

watch!(s, textinput( "Initial Value" , name = "field0", label = string( "Enter field0")))

the sampler fails to get the initial value, tracing this through

this.value = elem[self.attr] || elem.getAttribute(self.attr)

On an input field 'elem' references the outer paper-input-decorator and not the input field,

<paper-input-decorator is="undefined">
    <input is="core-input" name="line0" id="line0">
    <watch-state is="undefined"></watch-state>
</paper-input-decorator>

When the signal is sampled the result is an empty value unless the user has updated the field. As a kludge the following works, but is assuming that the first element is the input field.

this.value = elem[self.attr] || elem.getAttribute(self.attr)
        || elem.firstChild && ( elem.firstChild[self.attr] 
            || elem.firstChild.getAttribute(self.attr) )

macro api defines types in a local scope

When i remove the @doc calls in the return expression of macro api

macroexpand(quote @api test => TestType1 begin
    arg(a::FloatingPoint)
end end)

results in

begin 
    immutable TestType1
        a::FloatingPoint
    end
    test(#445#a) = TestType1(#445#a)
end

but normally, it expands to this

begin 
    immutable TestType1
        a::FloatingPoint
    end
    begin  # /home/brian/.julia/v0.3/Docile/src/Legacy/atdoc.jl, line 140:

Eager to play around with this, but I think I'm missing a file. Did you forget to commit it, or forget to not include it?

Virtual DOM updates to properties fail to trigger polymer 1.0 observers

I have a property on a DOM node (not an attribute). When a patch is applied which just changes the property it fails to trigger a polymer change event. The property is correctly updated and if I force a redraw it works. Any suggestions? As a workaround have placed a hash of the data as an attribute, which gets triggered correctly, this worked ok in 0.5 but with 1.0 the properties are updated after the attributes, so the data is not updated till after the event is triggered.

I can put the data on the attribute, but that makes for very large documents.

I'm assuming that the virtual dom is not fully using the shady API to make updates? Perhaps there should be an explicit call in the virtual dom for this form of update ?

Any help appreciated.

Open a Gitter chat room.

Gitter/Github integration can be done by adding a Gitter badge to the README.md.

Example for one of my repos:

[![Join the chat at https://gitter.im/Ismael-VC/HydrocarbonNets.jl](https://badges.gitter.im/Join%20Chat.svg)](https://gitter.im/Ismael-VC/HydrocarbonNets.jl?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)

This would allow us to have a good way to communicate and share stuff, it can be used with IRC also.

There are a lot of examples already: https://gitter.im/explore/tags/julia

Broken tex example on escher-jl.org

This is one of the first examples on the escher-jl.org homepage, and it doesn't work.

function main(window)
    push!(window.assets, "tex")

    tex("""f(x) = \int_{-\infty}^\infty
        \hat f(\xi)\,e^{2 \pi i \xi x}
        \,d\xi""")
end

When run, it gives this error message (in the browser window):

I've looked at the code that's actually running (and that does work), and I can't see what the difference is:

tex_eg = """f(x) = \\int_{-\\infty}^\\infty
    \\hat f(\\xi)\,e^{2 \\pi i \\xi x}
    \\,d\\xi
"""

I tried adding an extra backslash in front of the \,e^, since that was the only place with one \, but that did not cause any problems.

Naming clashes

Trying rule 2 example 1 from https://shashi.github.io/Escher.jl/ gives error in padding. Seems to apply to all calls of pad. Escher 0.1.0

Error:
'pad_outer' has no method matching pad_outer(::Measure{MeasureNil,MeasureNil}, ::FontColor)

Following the instructions results in an error
