Version 1.6.0

Bugfixes

• Fixed a bug where tcframe crashed when grading spec with multiple test cases mode, which has no sample test cases.
• Fixed a bug where a LINE() with only jagged vector contained an extra leading space.
• Fixed a bug where a LINES() with empty vectors contained extra spaces.

Enhancements

• Disallow specifying SIZE() after LINE() and RAW_LINE() instead of silently ignoring it.

Version 1.5.0

Bugfixes

• Fixed a bug where the spec file cannot be compiled when its absolute path contains spaces.

New features

• It is now possible to specify additional compilation flags, by setting the $TCFRAME_CXX_FLAGS environment variable.

Version 1.4.0

New features

• Interactive problems are now supported.
• It is now possible for scorers to specify partial points, by outputting OK\n<points>\n.
• It is now possible to assign points to subtasks.
• It is now possible to specify more than one output formats.
• Local grading now supports additional --brief argument to make the output concise.

Version 1.3.0

New features

• Subtask IDs specified by Subtasks() in TestCases() or TestGroupX() are now validated. It is an error now if you specify non-existing subtasks.
• BeforeOutputFormat() can be used to set the value of output variables that depend on input variables.

Version 1.2.1

Bugfixes

• Fixed a regression when I/O format segments do not pick up correct sizes if the sizes contain expressions that contain I/O variables. The value of the variables were evaluated the first time they were read.

  For example, if you declare SIZE(N - 1), it would always evaluate to SIZE(-1) (N = 0), which is incorrect. It is now fixed.

  Note that if the expression contains only a single variable (e.g. SIZE(N)), it is not affected and has always been correct.

Version 1.2.0

Bugfixes

• Fixed a regression when the final verdict of local grading of problems without subtasks is always AC.

New features

• It is now possible to write a custom program that checks whether the contestant's output is correct (instead of just comparing it with the official output). This is called custom scorer program.
• It is now possible not to generate test case output (.out) files.

Version 1.1.0

New features

• It is now possible to omit SIZE() for a LINES() segment, as long as it is the last segment in an I/O format.
• Brand new segments: RAW_LINE() and RAW_LINES(), which accept strings containing whitespaces.

Enhancements

• I/O format errors after a vector/matrix now have the last indices reported in the error message. For example,

  Before:

  Expected: <newline> after 'D'
  

  Now:

  Expected: <newline> after 'D[1]'
  

Version 1.0.1

Bugfixes

• Fixed a regression when I/O format segments do not pick up correct sizes taken from I/O variables.
• Fixed a regression when std::string cannot be used as variable type.

Version 1.0.0

First stable release. Almost a complete rewrite from 0.x. Focusing on syntax improvements and conceptual refinements.

BREAKING CHANGES

• Minimum GCC version is now 4.8.
• The source file of a runner program is now conceptually called "spec file", and is called spec.cpp instead of runner.cpp.
• A spec file now includes <tcframe/spec.hpp> instead of <tcframe/runner.hpp>.
• main() function in a spec file is not needed and must be removed.
• Problem specification is now called a "problem spec", and its class is ProblemSpec instead of Problem. It now inherits BaseProblemSpec.
• Generator specification is now called a "test spec", and its class is TestSpec instead of Generator. It now inherits BaseTestSpec.
• The container directory of a spec file is now conceptually called "problem package directory".
• The slug for a problem is now taken from the name of the problem package directory, and cannot be overridden via problem spec or command-line option.
• Config() in test spec is removed, so it is not possible to e.g. specify the solution command and test cases output directory in test spec.
• Config() in problem spec is split into GradingConfig() and MultipleTestCasesConfig().
• setTimeLimit() and setMemoryLimit in problem spec's Config() are now TimeLimit() and MemoryLimit() in GradingConfig().
• setMultipleTestCasesCount() in problem spec's Config() is now Counter() in MultipleTestCasesConfig().
• assignToSubtasks() in test groups is now Subtasks().
• Individual sample test cases now live in their own methods, SampleTestCaseX() where X is sample test case number.
• SAMPLE_CASE() is split into multiple calls: Subtasks(), Input(), and Output().
• FinalizeInput() is renamed to AfterTestCase().
• "Submission simulation" is now conceptually called "local grading".
• ./runner submit is now ./runner grade.
• --brief option for local grading is removed until there is clear use case for it.
• --slug option is removed.
• --solution-command option is simplified to --solution.
• --tc-dir option is renamed to --output.

New features

• tcframe helper script is introduced. It currently has 2 commands: tcframe build, which compile a spec file into a runner program, and tcframe version, which prints current tcframe version.
• A summary is printed after generation/grading, which shows whether or not there are failing test cases.
• It is now possible to specify the literal output for sample test cases, by calling Output() inside SampleTestCaseX().
• BeforeTestCase() to complement the new AfterTestCase(), which can be used to initialize input variables before each test case.
• For problems with subtasks, Constraints() can be used to specify global constraints that apply to every subtask.
• In ICPC-style multiple test cases in a file problems, it is now possible to specify a prefix that will be prepended to every output, by calling OutputPrefix() (e.g. OutputPrefix("Case #%d ");).

Enhancements

• Maximum X for TestGroupX(), SubtaskX() (and the new SampleTestCaseX()) is now 25.
• If there are errors in I/O format, previously the error was shown in every test case, resulting in spammy output. Now, it is reported only once before the test cases are evaluated.

Bugfixes

• When using multiple test groups in ICPC-style multiple test cases in a file problems, it was erroneously required to call assignToSubtasks({-1}). Now, it is not required.
• In e.g. this input segment LINE(A % SIZE(3), B), when B is not a supported type, tcframe reported the error as Variable type of%unsatisfied... due to a tokenization bug. It is now fixed.

Project development

• Repository moved to https://github.com/tcframe/tcframe.
• (Almost) every class now lives on its own file.
• Rewrite almost everything with better testability in mind. Now, we have decent unit tests.
• Use Google Test and Google Mock for unit tests.
• Add basic end-to-end tests for generation and local grading.
