Invalid burly URL with ivy-posframe, better-jumper, or bufler.el

[gagbo]

Before the gnarly backtrace, what I think happens. (I'm on 7c03d63)

I have a invalid read syntax # error when I try to restore frames with burly but it worked when I "only" save windows.

I dig up the backtrace and I think the issue is with the posframe-buffer frame-parameters (posframe-buffer posframe-parent-buffer), which are stored directly in their princ forms. Either that or still the better-jumper (better-jumper-struct) issue of #12, or the bufler-workspace-path-formatted . Or the name of the frames

Don't hesitate to search for the parameters in the page, otherwise it's kind of hard to see where the issues are

The url I tried to restore :

Hi Gerry,

I'm not sure I understand. Why would posframes be getting saved, especially ones from ivy-posframe? I must be missing something.

Anyway, do you mean that there's an un-read-able value in one of the frame or window parameters? If so, we should probably filter it out, unless it's absolutely necessary to restore it, in which case we'd have to figure out a workaround. I'd rather avoid adding workarounds for specific params though, so only if absolutely necessary. :)

I agree that they shouldn't be saved. I think it's saved because when I hit RET to give the burly-frames bookmark name, the posframe is still present. Is there a way to filter it out in burly-frames-url ?

I think that's the issue. From what I see, the possible culprits are :

• Better jumper
  (better-jumper-struct . #s(better-jumper-jump-list-struct (0 0 . [nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil]) -1))
  but I think it's cool to have the jump history restored. I can definitely live without it though
• Posframe
  (posframe-parent-buffer \"*doom*\" . #<buffer *doom*>)
  A predicate function to filter frames out of burly-frames-url would allow me to tinker with it and find a way to ignore posframes / childframes in general (company-box also uses childframes and they should be filtered out imo)
• Bufler
  (bufler-workspace-path-formatted . #(\"emacs_rs\" 0 8 (face outline-1)))
  I need the bufler workspaces to be saved, but only the -formatted one seems to be an issue.

Maybe a solution would be to check on save (during bufler-frames-url) whether the representation of a parameter starts with #, and ignore it at that point (maybe adding a warning in *Messages* to tell that those variables can't be saved because they just can't be restored)

Yeah, that explains it. Well, I guess we'll have to add something like burly-frame-predicate to filter out certain frames before they're saved.

...
(posframe-parent-buffer \"*doom*\" . #<buffer *doom*>)

That's almost certainly the problem, because buffers can't be read. I guess that filtering out the posframe will solve that problem as well, but in case it doesn't, you should be able to filter out that frame parameter already using the existing option.

I don't think that would be correct, because not all values with #-prefixed printable syntax are unreadable.

[alphapapa]

BTW, there is already code to remove buffers from properties in bookmarks, but it must not be catching the one that's causing this.

burly.el/burly.el

Line 359 in 7c03d63

when (or (bufferp value))

[gagbo]

BTW, there is already code to remove buffers from properties in bookmarks, but it must not be catching the one that's causing this.

That's because the value is not a buffer but a pair which cdr is a buffer. So I need to add it in the blacklist of parameters

[alphapapa]

If necessary, okay, but we should probably filter out posframes instead.

[gagbo]

Oh sure, for posframes filtering the whole frame is the solution, I was thinking about other packages that later might use the same trick
