Breaking changes:

• CLI argument is now done using the argparse library, changing the syntax to --long-options and being hopefully more familiar.

New features:

• Preprocessor macros using #define(identifier, macro)
• Built-in macros __STR__ and __CONSTEXPR__
• Defining preprocessor constants using #set(identifier, value)
• Preprocessors macros and constants are imported when using #import
• Static import using CLI
• Defining preprocessor constants using CLI

Fixed:

• Errors while printing some messages on Lua 5.1

Changes:

• Improve error handling (less stacktrace spam, better management of chunk names)

Fixes:

• Load Candran files before Lua ones

New features:

• Lua 5.4 and 5.2 targets
• const and close shortcuts

Bug fixes:

• table.unpack/unpack used in the correct Lua targets
• cancheck, package searcher error reporting and test suite improvements

New features:

• Added cancheck (luacheck for Candran)

Bug fixes:

• candran.make, .compile, .preprocess no longer throw errors but return nil, err
• can and canc output in case of error should now be similar to Lua

Added destructuring assignement.

• Added safe navigation operators
• Added method stubs
• Added if and while with assignments in the condition
• Better REPL which also now support linenoise for an ever betterer REPL (luarocks install linenoise)

• Added a PUC Lua 5.1 target
• Fixed using continue and break in the same loop

• Added canc -parse as a way to check for syntaxic errors
• Allowed canc and can to read from standard input
• Lua version target is now automatically detected
• Improve error reporting

• Added suffixable string and table litterals
• Fixed preprocessor misdetection of long strings and comments

Updated to LPegLabel 1.5 and fixed several bugs.
I've been using Candran for a while now without issues, so this should mean it's finally "robust enough".
