This patch make sure that function and macro definitions, as well as
do-blocks, end with an explicit `return` statement before the last
expression in the body. The following exceptions are made:
- If the last expression is a `for` or `while` loop (which both always
evaluate to `nothing`) `return` is added *after* the loop.
- If the last expression is a `if` or `try` block the `return` is only
added in case there is no `return` inside any of the branches.
- If the last expression is a `let` or `begin` block the `return` is
only added in case there is no `return` inside the block.
- If the last expression is a macro call the `return` is only added in
case there is no `return` inside the macro.
- If the last expression is a function call, and the function name is
`throw`, `rethrow`, or `error`, no `return` is added. This is because
it is pretty obvious that these calls terminate the function without
the explicit `return`.
Since adding `return` changes the expression that a macro will see, this
rule is disabled for function definitions inside of macros with the
exception of some known ones from Base (e.g. `@inline`, `@generated`,
...).
Closes#43.
- Listlike expressions (e.g. tuples, calls, paren-blocks, vectors) that
span multiple lines now always require a leading and a trailing
newline (and thus a trailing comma from previous listlike spacing
code). For example
```diff
-f(a,
- b)
+f(
+ a,
+ b,
+)
```
- Listlike expressions are now hard indents instead of the
soft/continuation style from before. This looks better.
- Vectors (K"vect" and K"ref") are now spaced like lists.
- Fix some bugs in spaces-around-operators when there where hidden
newlines at the beginning of the call chain.
Closes#9.
Using JuliaSyntax.GreenNode directly have worked for a long time, but at
this point it seems that it is easier to re-package the tree in a custom
type. This will be used to attach metadata to nodes, for example.
Also include the following renames:
- s/verified_children/verified_kids/
- s/children/kids/
- s/children′/kids′/
- s/children′′/kids′′/
- s/child/kid/
- s/child′/kid′/
- s/child′′/kid′′/
