Yuya Nishihara 1c0bde1a2b templater: add parsing rule for lambda expression ... A lambda expression will be allowed only in .map() operation. The syntax is borrowed from Rust closure. In Mercurial, a map operation is implemented by context substitution. For example, 'parents % "{node}"' prints parents[i].node for each. There are two major problems: 1. the top-level context cannot be referred from the inner map expression. 2. context of different types inserts arbitrarily-named keywords (e.g. a dict type inserts "{key}" and "{value}", but how we could know.) These issues should be avoided by using explicitly named parameters. parents.map(|parent| parent.commit_id ++ " " ++ commit_id) ^^^^^^^^^ global keyword A downside is that we can't reuse template fragment in map expression. Suppose we have -T commit_summary, -T 'parents.map(commit_summary)' doesn't work. # only usable as a top-level template 'commit_summary' = 'commit_id.short() ++ " " ++ description.first_line()' Another problem is that a lambda expression might be confused with an alias function. # .map(f) doesn't work, but .map(g) does 'f(x)' = 'x' 'g' = '|x| x'		2023-03-18 12:04:00 +09:00
