broken display of show_call_signatures

[escher9]

hi, I saw similar issue opened few days ago, but can't find exact one again, sorry if opening duplicate one

expect my vim to be above screenshot.. but

as following

seems very near to the ideal but still trailing with ' ' (small quotes) and also flickering

while typing arguments, sometimes display is flickering(on off on off...)

It seems that if above line is filled with some code, then flickering.

I'm sure that update to latest jedi (0.8.1_final0) and jedi-vim both.

my :ver is

:colorscheme?

[escher9]

colorscheme hybrid

[davidhalter]

It doesn't work with colorschemes.

[escher9]

did you mean colorscheme matters?
(I've tried another {color schemes and font}, but that was no solution.
eg, colorscheme : default
font : fixedsys ... etc.
)

font name in uploaded screenshot is 'inconsolata for powerline'

[davidhalter]

I'm pretty sure that it's either your colorscheme (don't use any) or another syntax modification. Just disable everything that might do syntax modifications and you'll be fine. :)

[escher9]

I understand, but how can I find one responsible for syntax modification?
if I thought that setting no other colorscheme results in ['default'] colorscheme...
I'm wrong?

[davidhalter]

No, you're right. But something else could do syntax modifications.

[escher9]

Ok I'll try from bare minimum to find that cause.

[davidhalter]

Did you try?

Also I just updated jedi-vim's split character up there (the 0 that you see are actually complicated unicode characters.

It doesn't work with colorschemes.

Really? Works for me.

@escher9
There have been fixes to this feature a few weeks ago.
Can you retry it, please?

Apart from that I've just thought that maybe a setting like magic or verymagic etc might have an influence, because patterns would be treated differently.

[davidhalter]

Really? Works for me.

Yeah, I'm probably just saying that, because it didn't work a while ago. But since you improved to the syntax file, it could work better?!

@davidhalter
Ah, that makes sense then.

I could reproduce the on-off flickering effect with minimal configuration with latest Jedi and Jedi-Vim.

It seems that the code line that is masked by the signature is not analyzed anymore. For example:

  import logging
  logging.basicConfig(

here the signature of basicConfig masks the import statement causing the signature disappear when key is pressed. Now the import is no longer masked and the signature is shown again when a key is pressed. This causes the on-off effect. The problem can be fixed by introducing any line in between so that the import statement is not masked.

The effect is not limited to import statements, but any statement that affects the signature of the edited method. This can be seen in the example presented by escher9.

@SamiAhola
Thanks for analysing.
I could imagine that temporarily disabling / ignoring the concealing would be required here. Although that might cause also some flickering then (always). But maybe it could be wrapped / get handled in a handler where Vim would not redraw anything.

[davidhalter]

@blueyed Since you've labeled it as a bug, what's the exact issue here?

[oblitum]

just to let the dots connected, cc #412
