Breaking changes

A different operator, ..() (instead of !!), is now expanded in meta-mode. In normal execution, this operator is not expanded, and is, instead stripped (i.e., .,(data()) becomes data()). See this wiki page for more information. (#59)

New features

New metaAction function, intended for executing code for its side effects while also capturing the source for code generation. This is useful for app setup code, such as library() calls, source-ing of supplemental .R files, loading static data sets, etc. (#71)

Known issues

bquote(splicing = TRUE) can't be used inside a metaExpr() context since the ..() operator is reserved for {shinymeta}'s quasi-quotation rules. Use {rlang}'s !!! operator for splicing instead of bquote().
metaRender() will throw a warning about deprecated env/quoted arguments when shiny::devmode(TRUE). This warning may be safely ignored and will be fixed in a future version.

0.1.0 (unreleased)

Initial version, as presented at useR 2019.
