NOTE: I use the symbol ␣ to represent the character SPACE (U+0020) for visibility.
I have a template like this:
${1:$$(yas-choose-value (with-current-buffer "foo-buf" (foo-get-name-list)))}␣[label="$1"];
When I pick an entry "Foo" from the list returned from foo-get-name-list, I expect to see an output line like
Foo␣[label="Foo"]
Instead, however, I get
Foo[label="Foo"]
How can I preserve that SPACE after Foo and before the LEFT SQUARE BRACKET?
The problem is that the $$(yas-choose-value... is not expanded before the indentation kicks in, so when yasnippet indents the snippet, the buffer text looks like: ␣[label=""]; and the space is removed by indenting. You can disable indentation for a snippet by adding # expand-env: ((yas-indent-line nil)) to the snippet.
I'm not sure yet whether to classify this as a yasnippet bug or not.
