Kvara is an assembler with i18n (internationalization) support for the Varvara/Uxn ecosystem, forked from the reference uxnasm assembler implemented in C.

• Kvara means fourth in Esperanto.
• Kvara rhymes with Uxn's Varvara.
• Kvara is the fourth Uxntal assembler that I have used, the others were: uxnasm, asma and drifblim.
• Kvara is also a reference to the Forth programming langauge, which led me to the Uxn ecosystem.

• English
• Spanish (es)
• Esperanto (eo)
• Toki pona (tok)

$ make # English version. $ make all # All versions. $ make es # Spanish version. $ make eo # Esperanto version. $ make tok # Toki pona version.

$ kvrasm[-es|-eo|-tok] input.kvr[es|eo|tok] [output.rom]

$ make test # Test English version. $ make test-all # Test all versions. $ make test-es # Test Spanish version. $ make test-eo # Test Esperanto version. $ make test-tok # Test Toki pona version.

$ make install # Install English version. $ make install-all # Install all versions. $ make install-es # Install Spanish version. $ make install-eo # Install Esperanto version. $ make install-tok # Install Toki pona version.

The executables are installed at ~/bin, make sure that this directory is in your PATH and that you have sourced your shell configuration file, for example ~/.bashrc or start a new shell session for Kvara assembler(s) to be available from any directory.

$ make install $ echo "export PATH=$PATH:~/bin" >> ~/.bashrc $ source ~/.bashrc

• Kvara supports \ comment backslash space Forth style comments, these are not part of the Uxntal specification which only supports ( comment ) parenthesis Forth style comments (there must whitespace after the opening ( and closing ) parenthesis).

• In order to offer full compatibility with other standard Uxntal assemblers, ease porting standard Uxntal to a supported Kvara language and also porting from one supported kvara language to another there is the Kvara porter at utils/kvrprt.

$ kvrprt source.kvr[lang] # Creates: source.tal $ kvrprt source.tal lang # Creates: source.kvr{lang}

• Implement kvrptr (Kvara porter).
• Explain how to contribute and add a new language.
• Implement another utility to scafold and make easier adding new languages.
• Use the opcode test for all languages.
• Improve opcode tests.
• If no output file name is given, by default use the input file name and save rom to the current working directory.
