Full Changelog: v0.6.0...v0.7.0

0.6.0 - 2022-01-29

0.6.0 - 2022-01-29

Added

• Added new syntax for integrating with the NREL Building Component Library.

Changed

• Now releasing executable as a single file.
• Numbers are now printing with 4 significant figures on output.

0.5.0 - 2021-09-17

Added

• Added new dedicated operators for mapping, filtering, and piping. The operators are |=, |>, and ->.

• Added new possible terminator for idf objects, $. This is important when building objects that can have arbitrary lengths, such as Wall:Detailed. There will likely be a different allowed character for aesthetic purposes in future version.

• Added range syntax. Can quickly make lists with integers like 0..10.

• New log statement. Allows for simple debugging. Prints value of an expression to standard error.

• Documentation is now available in HTML form. See it live at neobem.io.

Changed

• BREAKING: The order of the parameters for the map and filter function have swapped. Old programs will have to swap the order or move to the more concise operators |= and |>.

• BREAKING: The order of the parameters for the join function has swapped. Old programs will also have to swap this.

Fixed

• Vast improvements to the formatter. - The documentation for the 'has' function was previously incorrect on the order of the parameters. - Documentation that attempted to use a logarithm now uses the actual logarithm function.

v0.4.0

0.4.0 - 2021-07-22

Added

• Ability to load in JSON data
• Ability to load in XML data
• A print statement is now allowed within a function. Previously it
  was only allowed at the root scope of a file.
• Added three new built in functions: type, guid, and replace.
• Added formatting option -f or --fmt, analogous to gofmt.
• When loading a delimited text file, there is an option to skip a
  number of header rows.

Changed

• BREAKING: The grammar for imports was updated. The as 'name'
  token has been now forced to be an identifier, not a string. All
  strings will need to have the quotations removed, and the name made
  into a valid identifier.

• The URI portion of the import statement now is generalized to be an
  expression, instead of a string. This means that the URI for an import
  can now be dynamic. This is not a breaking change.

• Box characters can now be used for inline data tables. Generally, the
  formatter will be used to redraw the inline data tables with these
  box characters.

Fixed

• The program now exits immediately on any errors in lexing or parsing.
  Previously would still try to walk the broken syntax tree.

v0.3.0

0.3.0

Changed

• BREAKING: Structures now act as true associative arrays. You can
  use any string expression as the key.

• BREAKING: Because the structures can now use any string as the
  key, the sanitation of column headers when loading from Excel has been
  removed.

• BREAKING: Inline data table headers are now strings, not identifiers.

Added

• String escaping is now supported for the following characters:

  • '\n' for newline
  • '\r' for carriage return
  • '\t' for tab
  • '\'' for single quote
  • '\\' for the backslash character itself

• New built in functions:

  • keys: returns all the current keys in a structure
  • has: check whether a structure has a given key initialized
  • init: return all but the last element in a list
  • last: return the last element in a list
  • join: join a list of strings together with a separator string

• Pretty print the IDF objects by default.

• Added ability to create empty structure.

• Added equality comparisons between booleans, empty lists (like list == []), and comparison of lists with different lengths.

• Trailing commas are now allowed in both lists and structures ([1, 2, 3,] is valid).

• '+' operator is now defined for 'string + number'

• '+' operator is now defined for two structures.

Fixed

• Comments called from within functions now have replacements made.

v0.2.0

0.2.0

Changed

• Executable is now called nbem instead of bemp.

Added

• Vast documentation additions, including 'Getting Started' section.
• Boolean literal syntax, (i.e. true, false, ✓, ✗).
• Let binding syntax.
• Replacement ability in comments.
• Loading from Excel functionality.
• Grammar and functionality for exports.
• Ability to import from web location.
• Ability to read input from standard input.

Fixed

• Printing of lists of lists now flattens output as expected.
• lambda expressions can now properly return values.
• Variable assignment with nested structures now works as expected.

Removed

• data syntax. Replaced with load function.
