The main HCL package is more visible this way, and so it's easier than
having to pick it out from dozens of other package directories.
|
|
This is in preparation for the first v2 release from the main HCL
repository.

Waiting for TokenCHeredoc never ends since scanTokens() does not
produce
TokenNewlines inside heredocs.

closes #65
- add missing edge case for two interpolated items next to each other
- add tests for both quote and heredoc cases
|
|
The symmetrical spaces around colons in conditionals are important for
familiarity with C-like languages, so we'll instead accept spaces around
colons in our HCL2-unique "for expression" construct.
|
|
Leading whitespace is significant in heredocs, so we'll avoid making any
indentation adjustments for lines between OHeredoc and CHeredoc.
This fixes #31.

Our normal ruleset thinks that the "in" keyword here is a variable
reference and so writes it as "in[y]". Since there's never any reason for
a variable to appear immediately after another variable, we can check
for a preceding identifier as a heuristic to recognize whether in is
probably being used as a keyword rather than as a variable.
This is not exact, but the only time this should be a false positive is
if there were a syntax error in the input, and we don't make any
guarantees about the result in that case anyway.
This fixes #52.

This relaxes our previous spec to include a special form from HCL 1:
foo { bar = baz }
Although we normally require each argument to be on a line of its own, as
a special case we allow a block to be defined with a single nested
argument all on one line.
Only one nested argument definition is allowed, and a nested block
definition like "foo { bar {} }" is also disallowed in order to force the
more-readable split of bar {} onto a line of its own.
This is a pragmatic addition for broader compatibility with HCL 1-oriented
input. This single-line usage is not considered idiomatic HCL 2 and may
in future be undone by the formatter, though for now it is left as-is
aside from the spacing around the braces.
This also changes the behavior of the source code formatter to include
spaces on both sides of braces. This mimicks the formatting behavior of
HCL 1 for this situation, and (subjectively) reads better even for other
one-line braced expressions like object constructors and object for
expressions.

Some of these fail in HCL1 fmt
|
|
This is another heuristic because the "[" syntax is also the tuple
constructor start marker, but this takes care of the common cases of
indexing keywords and bracketed expressions.
This fixes #29.

This is a super-invasive update since the "zcl" package in particular
is referenced all over.
There are probably still a few zcl references hanging around in comments,
etc but this takes care of most of it.
|
|
The main "zcl" package requires a bit more care because of how many
callers it has and because of its two subpackages, so we'll take care
of that one separately.
