Hi all, Within the channel-based plugin govim (https://github.com/govim/govim), the bulk of functionality is triggered by user actions in Vim.
However, certain events are triggered entirely independently of Vim, for example a list of diagnostics arriving from an LSP server, the LSP server asking govim to show an error message. There are others. When handling these non-Vim triggered events, any call from govim to Vim is effectively racing (i.e. in a race condition) with whatever Vim might be doing at the time. For example, we might happen to call from govim -> Vim while Vim is in the middle of handling a listener_add callback that itself calls ch_evalexpr which results in a call Vim -> govim. One thing we're not clear on is whether we should be "scheduling" certain things in Vim. The channel docs (https://github.com/vim/vim/blob/master/runtime/doc/channel.txt) highlight that we should be checking what mode the user is in, but I don't think this handles the case described. What do I mean by scheduling? As I understand it, if when handling a non-Vim triggered event we instead made a call into Vim that did something like: timer_start(0, { -> dostuff() }) then dostuff() will be "scheduled" by Vim "at a convenient time". Would this approach work? We're seeing some tests randomly failing and this "scheduling" problem is our current hypothesis. But our understanding here is vague, so any suggestions/guidance appreciated. Thanks, Paul -- -- You received this message from the "vim_dev" maillist. Do not top-post!
