Delayed appearance of git symbols when using async

[tmpm697]

I use your latest commit that enable async - thanks for that, but symbols that display for e.g: when there's file added to repo or file under repo change delayed to appear when spawn new shell.

Steps to produce:

1. clone a random repo
2. cd to repo; modify file, touch new file ..etc
3. in tmux create new pane ( my tmux and zsh will remember last directory and use it for new spawned pane's shell)
4. you see delayed of new shell when display git's symbols, for e.g: user@localhost ?>_>% user@localhost will display very fast but git's symbol ?>_> has some delay when display.

I believe this due to we do async git but did not async other part of prompt and sync all of parts, what do you think?

That is correct. :heavy_check_mark: Since vcs_info is calculated asynchronously, the ${vcs_info_msg_0_} variable in the prompt has no initial value and is therefore rendered as nothing. :running_man: Later, when the vcs_info calculation job is finished, it triggers a chain reaction that populates the ${vcs_info_msg_0_} variable and re-renders the prompt. :sparkles: Now, the calculated vcs_info output suddenly appears in the prompt.

PROMPT='...${vcs_info_msg_0_}...'

Is there away to sync all parts of prompt or make all parts appears at the same time? Sorin prompt seem achieved this. @sunaku

Wouldn't making all parts appear at the same time defeat the purpose of async? :thinking: You'd essentially have to wait for the slowest part (i.e. vcs_info) to finish before displaying the prompt (so that all parts appear at the same time), and this would slow it down.

Make sense.
