Windows: Long package silently not opened in browser

[tfiers]

depgraph_web(:Plots), eg

url(:Plots,) shows that truncated..

[tfiers]

• [x] figure out threshold (or some reasonable 'lower bound')
• [ ] copy to clipboard instead

[tfiers]

another one: depgraph_web(:OrdinaryDiffEq)

[tfiers]

Also, that takes a long time, #TTFX. So let's go to

• 82

[tfiers]

(Actually, OrdinarryDiffEq takes longer to crawl than Plots)

Ok this works:

julia> link=PkgGraph.url(PkgGraph.depgraph_as_dotstr(:OrdinaryDiffEq));
julia> run(pipeline(`echo $link`, `clip.exe`))

(and then pasting in browser) (btw, that is not a useful viz. link)

[tfiers]

(it's not better w/ jll and stdlib filtered out! (link))

[tfiers]

aha, interesting: with our deved DefaultApp (

• https://github.com/tpapp/DefaultApplication.jl/pull/21

)

julia> DefaultApplication.open(link)

aha, but it works on WSL:

julia> ope(path) = run(`powershell.exe -NoProfile -NonInteractive -Command start \"$(path)\"`);
julia> ope(link);

(works)

So. Is it on windows only this bug?

(wow. crazy long on Windows, #windows IO is slower than linux:

compare w/ asciinema rec here:

• https://github.com/tfiers/PkgGraph.jl/issues/97#issuecomment-1407439650

ok that was :Plots, but still. I remember ODE on WSL being ~14 seconds, not two minutes )

but ok, yes, it is a windows only thing:

(could also be the case on mac, dunno) Can I run(explorer) on it directly? Does that work w/ urls? (or, run run(cmd.exe /c start …)) nope:

So, we know thr: https://learn.microsoft.com/en-us/troubleshoot/windows-client/shell-experience/command-line-string-limitation

"#how-to-work-around-the-limitation": write to tmp file, then pipe through. ok sure (could be a defaultapp pr)

hah, maybe PowerShell doesn't have this?

ah no,

julia> run(`powershell.exe -NoProfile -NonInteractive -Command start $link`)

gives same error (IOError: could not spawn .. : name too long (ENAMETOOLONG))

[tfiers]

Current status: will be fixed once

• https://github.com/tpapp/DefaultApplication.jl/pull/21

is merged and released

[tfiers]

Should be released and thus fixed: https://github.com/tpapp/DefaultApplication.jl/commits/master Might need a lower bound on this dep version. And to check.
