Release 1.3.0

on GitHub

Added

• log2 and log math functions in @stdlib/math: PR #166
• Reserve mode constants in @stdlib/reserve, namely ReserveExact, ReserveAllExcept, ReserveAtMost, ReserveAddOriginalBalance, ReserveInvertSign, ReserveBounceIfActionFail: PR #173
• Support for string escape sequences (\\, \", \n, \r, \t, \v, \b, \f, \u{0} through \u{FFFFFF}, \u0000 through \uFFFF, \x00 through \xFF): PR #192
• JSON Schema for tact.config.json: PR #194
• Struct fields punning, i.e. {foo, bar} is syntactic sugar for { foo: foo, bar: bar }: PR #272
• The ability to use dump function on the values of the Address type: PR #175
• The non-modifying StringBuilder's concat extension function for chained string concatenations: PR #217
• The toString extension function for Address type: PR #224
• The bitwise XOR operation (^): PR #238
• The isEmpty extension function for the Map type: PR #266
• The pow2 power function with base 2: PR #267
• The try and try-catch statements: PR #212
• The del method for the Map type: PR #95
• The -h/--help, -v (short for --version), -p (short for --project), --func (for only outputting FunC code) and --check (for only doing the syntax and type checking) command-line flags: PR #287
• The mode enum in project properties of tact.config.json for specifying compilation mode: full (default), funcOnly (only outputs FunC code and exits), or checkOnly (only does the syntax and type checking, then exits): PR #287
• The foreach loop for the Map type: PR #106

Changed

• The implicit empty init function is now present by default in the contract if not declared: PR #167
• Support trailing commas in all comma-separated lists (struct instantiations, initOf arguments, init() parameters, inherited traits via with, function arguments and parameters): PR #179 and PR #246
• @stdlib/stoppable now imports @stdlib/ownable so the programmer does not have to do it separately: PR #193
• The newAddress function now evaluates to a constant value if possible: PR #237
• The pow power function could only be used at compile-time, but now it is available in the standard library and can be called both at runtime and compile-time: PR #267
• The dump() and dumpStack() functions now print the file path, line number, and column number in addition to the data: PR #271
• Use | instead of + for send mode flags because the bitwise OR operation is idempotent and hence safer: PR #274
• Bumped the versions of @ton/core and ohm-js to the most recent ones: PR #276
• Generated .pkg-files always use POSIX file paths (even on Windows): PR # 300
• The -p/--project flags now allow specifying more than one project name. Additionally, they also require a --config flag to be specified: PR #287
• Command-line interface now allows compiling a single Tact file directly, without specifying a config: PR #287

Fixed

• Escape backticks in error messages for generated TypeScript code: PR #192
• Integer overflows during compile-time constant evaluation are properly propagated as a compilation error: PR #200
• Incorrect "already exists" errors when using the toString and valueOf identifiers: PR #208
• Empty inherited trait lists after with keyword are now disallowed: PR #246
• Allow chaining method calls with !!, for instance, map.asCell()!!.hash() is grammatically correct now: PR #257
• Precedence levels for bitwise operators, equality and comparisons now matches common languages, like JavaScript: PR #265
• Incorrect variable scoping in the repeat, while and until loops: PR #269
• FunC compilation errors when trying to dump() values of the Cell, Slice, Builder and StringBuilder types: PR #271
• Tact's CLI returns a non-zero exit code if compilation fails: PR #278
• Use the most recent version of the FunC standard library stdlib.fc: PR #283
• The WASM version of the FunC compiler has been updated to 0.4.4 and patched to work on larger contracts: PR #297
• The return-statement reachability analysis: PR #302
