v6.2.0

This release

• fixes a panic occurring when ranging over a channel or other custom rangers without setting the value to variable (#200)
• speeds up accessing struct fields and eliminates allocations for many uses of resolveIndex() (#201)
• improves the performance of intsRanger by eliminating allocations (#202)

As a result, it's now possible to execute templates with guaranteed zero memory allocations (during execution) by using a combination of int and custom rangers and either simple field access or custom renderers.

Thank you, @matheusd for submitting these PRs!

Full Changelog: v6.1.0...v6.1.1

v6.1.0

Added dump() built-in function for development/debugging: https://github.com/CloudyKit/jet/blob/master/docs/builtins.md#dump
Thanks @jan-herout for contributing this! (#189)

v6.0.2

Non-breaking workaround for #187: comments were not parsed correctly when using custom delimiters.

v6.0.1

The in-memory template loader introduced in v6.0.0 is now safe for concurrent use. (3f2f52a)

v6.0.0

Version 6 brings Go API improvements, mainly from #182 and #183. Take a look at the breaking changes documentation for a detailed overview. There are no changes to the template language.

v5.1.0

With version 5.1.0, Jet gains whitespace control syntax! The PR is here, and it's explained in the docs here.

v5.0.3

Bugfix release: Concurrent use of a Set of templates could cause data races via a shared array for the argument values of function calls using the reflect package. 0e59615 is the only commit since v5.0.2.

v3.0.1

This is just v3.0.0 plus #176. Thanks @tooolbox for the backport!

v5.0.2

Bugfix release: When calling variadic functions, the list of argument expressions was not correctly mapped to the variadic argument slice needed to call the function using reflection. See #171 for more information. Thanks, @alresvor!

v5.0.1

Bugfix release: When using discard syntax in a simple "let" assignment, i.e. one where the right side does not return an optional second value like a map lookup for example, the right side wasn't evaluated. For example, these all worked as expected and the right side was evaluated:

_ := myMap["foo"]
_ = myMap["foo"]

_, ok := myMap["foo"]
_, ok = myMap["foo"]

_ = foo()

But this did not actually execute foo():

_ := foo()

f67efbc fixes this case and is the only commit in v5.0.1 that isn't in v5.0.0.
