v1.4.0 (St Nicholas' Day Release)

This release improves the lambda function feature of spiff and supports the possibility to use spiff as go library.

• It is possible now to declare optional parameters for lambda functions by specifying defaults for trailing parameters.
• This is attended by the introduction of a currying operator (*() that works for lambda functions as well as for built-in functions of spiff.
• Support of indexed and named arguments in function calls and currying expressions.
• Additionally inline list expansion is supported now by the list expansion postfix operator (...) usable in argument lists or list literals.
• It is possible to handle templates as go objects and to process input documents using those templates without file system usage.

A new marker (&default) is supported now. It can be used to define default values for downstream nodes.
In contrast to &inject those settings do not override existing downstream settings.

Several new built-in functions are added:

• intersect for list intersection
• reverse for reversing the order of list entries.
• multiple regexp matches
• md5crypt support to generate linux password hashes
• generation of ssh public key format for generated x509 keys

Fixes:

• chained or expressions

The Dynamic Release

This release opens a new dimension for generating deployment manifests by supporting state and access to status information of deployments. This can be used to influence the generation of multiple inter-dependent deployments described in a single yaml template.

Here is the list of new features:

• marshal and unmarshal yaml and json strings from/as parts of the yaml document (parse, asjson and asyaml)
• stream content from the yaml document into a command processing and catch its result (pipe)
• function catch offers a possibility to handle evaluation errors
• function sync supports the synchronization of the template processing with external content
• functions bcryptand bcrypt_checkcan be used to generate and validate bcrypt based password hashes
• functions lower, upper and sort (with lambda compare funtion support)
• function rand to generate random numbers and strings
• function write writes content to files
• option --path can be used to specify a sub path of the document for the output
• option --split can be used to split a list output into a multi document stream
• state support using option --state
• extend the reference lookup for nested merge function with access to outer bindings
• enrich the __ctx field to offer access to all levels of outer documents in merge functions.
• map mode for map statement
• filtering of maps and lists via select statement
• importing of multi documents (as list of nodes) with read mode importmulti and multiyaml
• parsing to and reading of templates
• access to defining scope in lambda functions using scope literal _
• access to template and definining scope in templates using scope literal _
• scoped expressions with ( "alice"=25 ) expr
• scope literal __
• support of negative list indices
• support of regular list index syntax in dynaml without dot
• support of json like string literals in dynaml
• omit _ in inline lambda expressions as part of a statement syntax (like map[]) to support
  such statements in self-reflective lambdas
• improved error reporting with call stack of lambda function and location of parsing errors in dynaml
  expressions.
• function lookup_file to lookup files and directories in a list of directories
• function list_files to list directory entries.
• function tempfile to use data files temporarily during the template processig
• function split now supports splitting for maximum line length
• function write now supports binary data
• expression merge none disables field merging
• operator // to default invalid values
• function stub now accepts a field list argument, also
• function merge now supports a list of maps as argument
• function x509parsecert
• function validate can be used to validate expressions using a set of own or built-in validators
• regexp variants for splitand replace
• replace with lambda based replacement
• offering some dynaml libraries
• generating archives
• node validation
• encryption/decryption
• support <<<: as substitute for <<: to support newer yaml parsers
