Inspired by the utility library underscore.js, we've added a bunch of new utility functions to Sprig. Many of these are designed to work on dict and list types (and for the time being, on tuple as well).

Highlights:

• semver and semverCompare were added by popular demand.
• list replaces tuple
• join was fixed
• Added:
  • first
  • last
  • intial
  • rest
  • prepend
  • append
  • toString
  • toStrings
  • sortAlpha
  • reverse
  • coalesce
  • pluck
  • pick
  • compact
  • keys
  • omit
  • uniq
  • has
  • without

This release adds two new sets of functions:

• First, it provides access to several path functions (base, dir, clean, ext, and abs)
• Second, it adds functions for mutating dictionaries (set, unset, hasKey)

This release adds a uuidv4 template function for generating UUIDs inside of a template.

Four new functions from the strings package have been exposed as template functions. Following established conventions, we've reversed the order of parameters to better suite template usage:

{{"$5.00" | trimPrefix "$"}}

Additionally, new aliases have been added for a few functions that didn't follow the naming conventions. There is now a trimAll (used in preference to trimall) and abbrevBoth (in preference to abbrevboth).

At the 3.0 release (whenever that happens), trimall and abbrevboth will be removed.

This release adds two functions: until and untilStep. These functions generate integer slices. They are designed to be used for iteration:

{{range $i, $val := until 5}}{{end}}

In the above, $i is the index, and $val is the value. Both will iterate from 0 to 4.

For more control, you may use untilStep. The above can be replicated exactly:

{{range $i, $val := until 0 5 1}}{{end}}

untilStep takes three arguments: untilStep $start $end $step:

• $start: The starting value
• $end: The end value
• $step: The increment value

Here's an example that will produce even numbers less than 10:

{{range $i, $val := until 0 10 2}}
  {{$val}}
{{end}}

The above will produce

0
2
4
6
8

New functions:

• cat: Concatenate strings with whitespace separators.
• replace: Replace parts of a string: replace " " "-" "Me First" renders "Me-First"
• plural: Format plurals: len "foo" | plural "one foo" "many foos" renders "many foos"
• indent: Indent blocks of text in a way that is sensitive to "\n" characters.

Experimenting with some new crypto functions for orchestration tasks, we've added a genPrivateKey function. Thanks to @bacongobbler for the pull request.

This release adds the following:

• default now prints the default value when it does not receive a value down the pipeline. It is much safer now to do {{.Foo | default "bar"}}.
• Added accessors for "hermetic" functions. These return only functions that, when given the same input, produce the same output.

This release adds a number of new functions:

• min complements max (formerly biggest)
• empty indicates that a value is the empty value for its type
• tuple creates a tuple inside of a template: {{$t := tuple "a", "b" "c"}}
• dict creates a dictionary inside of a template {{$d := dict "key1" "val1" "key2" "val2"}}
• Date formatters have been added for HTML dates (as used in date input fields)
• Integer math functions can convert from a number of types, including string (via strconv.ParseInt).

Because we switched from int to int64 as the return value for all integer math functions, the library's major version number has been incremented.

This release features a few improvements.

• Added quote and squote functions for quoting strings.
• Addedb32enc and b32dec for Base32 encoding and decoding.
• add now takes varargs: {{ add 1 2 3 }}
• biggest now takes varargs: {{ biggest 5 6 4 }}
• README is updated

Our tests indicate that making functions variadic seems to be backward compatible, but we're only doing a few this release in case there are some use cases we hadn't thought of.

• Added #4: Added contains function. strings.Contains, but with the arguments switched to simplify common pipelines.
• Added Travis-CI testing support
