spike: fd:11: hFlush: resource vanished (Broken pipe) #1

Closed juhp closed 7 years ago

juhp commented 12 years ago

Perhaps I am missing something obvious but if I try to run spike on Fedora 16 I get:

~/haskell/spike:master$ spike 
"CALL: viewPage"
"CALL: refreshLayout"
"strange stuff."
"digraph \"Browse tree\" {\ngraph [\nfontname = \"Helvetica-Oblique\",\npage = 10\nsize = 30\n ];\nd0 [URL=\"page://0\", shape=polygon, fixedsize=true, fontsize=8, width=1.25, height=0.25, tooltip=\"https://google.com\", label=\"https://google.com...\"];\nd1 [URL=\"page://1\", shape=polygon, fixedsize=true, fontsize=8, width=1.25, height=0.25, tooltip=\"http://news.google.com\", label=\"http://news.google...\"];\n}"

Do you have 'dot' command from Graphviz suite installed? I think it's trying to execute it and doesn't find it. But I might be wrong here - if this is not the case please do 'strace spike' and send the results.

Doh - right you are. Thanks that gets me running.

Perhaps I am missing something else too. The spike tree browser graph is not rendering for me:

This page contains the following errors:

error on line 21 at column 1: Encoding error
Below is a rendering of the page up to the first error.

The svg produced by dot must be somehow wrong or it doesn't produce any output. Try to run spike from console and look at standard output. It should print both input for dot and output received (with error codes and such).

Seems the output is too long to paste here:

Anyway, any plans to move move away from calling out to graphviz?

Tener commented 12 years ago

This is doable, for example svg can be rendered with this package: http://hackage.haskell.org/package/yjsvg I'll make an issue on issue tracker from it later.

I have no idea though where the error comes from: there is nothing suspicious on line 20 or anything near it.
