select breaks syntax highlighting in bash

[DarioDarko]

Steps to reproduce

set filetype to sh or bash use 'select' as a command argument without surrounding quotes watch the syntax highlighting break

example:

while true
do
	anycommand select something
done

i randomly discovered this because copyq has a select argument, that i use in a script

Expected behaviour

'select' should not break the syntax highlighting if its used as an argument for a command. the syntax recognition logic should only trigger if its at the very beginning of the line, after && semicolon etc

I don't see this. Can you please verify using vim --clean

Hm, did you use bash initially? I only see this when using bash in the shebang line. This seems to happen when the syntax script determines a bash script, because bash "knows" select name [ in word ] ; do list ; done, which the syntax script tries to match here. And since there is a missing do here, it matches the done with an error. You can workaround this by setting :let b:is_posix=1.

yes normally i use bash, but for me this happens with sh as well

btw this does not only affect select. same with while, until, for, etc

Yeah, for the same reason, you are using reserved words which the syntax script tries to match against the expected syntax.

:let b:is_posix=1

So does this help?

yes, i understand the issue. wouldt it be pretty simple to fix that in the syntax script?

unfortunately no

You need to reload the file after :let b:is_posix=1 using :e!, otherwise setting the buffer local var happens too late.
