Snowball was originally designed and built by Martin Porter. Martin retired from development in 2014 and Snowball is now maintained as a community project. Martin originally chose the name Snowball as a tribute to SNOBOL, the excellent string handling language from the 1960s. It now also serves as a metaphor for how the project grows by gathering contributions over time.} %global langlist %{expand:Algorithms are available for the following languages: - Arabic - Armenian - Basque - Catalan - Danish - Dutch - English (Standard, Porter) - Finnish - French - German - Greek - Hindi - Hungarian - Indonesian - Irish - Italian - Lithuanian - Nepali - Norwegian - Portuguese - Romanian - Russian - Serbian - Spanish - Swedish - Tamil - Turkish - Yiddish} %description %desc The Snowball compiler translates a Snowball program into source code in another language - currently Ada, ISO C, C#, Go, Java, Javascript, Object Pascal, Python and Rust are supported. What is Stemming? Stemming maps different forms of the same word to a common "stem" - for example, the English stemmer maps connection, connections, connective, connected, and connecting to connect. So a search for connected would also find documents which only have the other forms. This stem form is often a word itself, but this is not always the case as this is not a requirement for text search systems, which are the intended field of use. We also aim to conflate words with the same meaning, rather than all words with a common linguistic root (so awe and awful don't have the same stem), and over-stemming is more problematic than under-stemming so we tend not to stem in cases that are hard to resolve. If you want to always reduce words to a root form and/or get a root form which is itself a word then Snowball's stemming algorithms likely aren't the right answer. %package -n libstemmer Summary: Stemming algorithms written in C %description -n libstemmer Stemming algorithms written in C. %desc %langlist %package -n libstemmer-devel Summary: Developer files for libstemmer Requires: libstemmer%{?_isa} = %{version}-%{release} %description -n libstemmer-devel Header files and shared library links for libstemmer. %ifarch %{java_arches} %package -n snowball-java Summary: Stemming algorithms written in Java BuildArch: noarch %description -n snowball-java Stemming algorithms written in Java. %desc %langlist %endif %package -n python%{python3_pkgversion}-snowballstemmer Summary: Stemming algorithms written in Python 3 BuildArch: noarch %description -n python%{python3_pkgversion}-snowballstemmer Stemming algorithms written in Python 3. %desc %langlist %prep %autosetup -p1 -b 1 sed -i s,python3,python%{python3_version}, GNUmakefile # Fix an RST error sed -i 's/\(libstemmer_c-\)\*/\1\\*/' doc/libstemmer_c_README %build # Build the compiler and C library sed -i 's|^\(CFLAGS=\).*|\1%{build_cflags}|' GNUmakefile %make_build %ifarch %{java_arches} # Build the Java algorithms %make_build dist_libstemmer_java cd dist tar xf libstemmer_java-%{version}.tar.* cd - cd dist/libstemmer_java-%{version} mkdir classes javac -d classes java/org/tartarus/snowball/{,ext/}*.java jar -c -f snowball.jar -C classes org/ cd - %endif # Build the python algorithms %make_build dist_libstemmer_python cd dist tar xf snowballstemmer-%{version}.tar.* cd - cd dist/snowballstemmer-%{version} %pyproject_wheel cd - # Convert the RST docs to HTML for readability rst2html --no-datestamp README.rst README.html rst2html --no-datestamp doc/libstemmer_c_README libstemmer/README.html rst2html --no-datestamp doc/libstemmer_java_README java/README.html rst2html --no-datestamp doc/libstemmer_python_README python/README.html %install # Install the snowball compiler mkdir -p %{buildroot}%{_bindir} cp -p snowball stemwords %{buildroot}%{_bindir} # Install the C library mkdir -p %{buildroot}%{_libdir} cp -p libstemmer.so.0.0.0 %{buildroot}%{_libdir} ln -s libstemmer.so.0.0.0 %{buildroot}%{_libdir}/libstemmer.so.0 ln -s libstemmer.so.0 %{buildroot}%{_libdir}/libstemmer.so # Install the C headers mkdir -p %{buildroot}%{_includedir} cp -p include/*.h %{buildroot}%{_includedir} %ifarch %{java_arches} # Install the Java algorithms cd dist/libstemmer_java-%{version} mkdir -p %{buildroot}%{_javadir} cp -p snowball.jar %{buildroot}%{_javadir} cd - %endif # Install the python algorithms cd dist/snowballstemmer-%{version} %pyproject_install %pyproject_save_files snowballstemmer cd - %check # Check the compiler export LD_LIBRARY_PATH=%{buildroot}%{_libdir} mv ../snowball-data-master ../snowball-data make check %ifarch %{java_arches} make check_java %endif make check_python %files %doc NEWS README.html %license COPYING %{_bindir}/snowball %{_bindir}/stemwords %files -n libstemmer %doc libstemmer/README.html %license COPYING %{_libdir}/libstemmer.so.0* %files -n libstemmer-devel %doc examples/stemwords.c %{_includedir}/libstemmer.h %{_libdir}/libstemmer.so %ifarch %{java_arches} %files -n snowball-java %doc java/README.html %license COPYING %{_javadir}/snowball.jar %endif %files -n python%{python3_pkgversion}-snowballstemmer -f %{pyproject_files} %doc python/README.html %license COPYING %changelog * Sat Jan 21 2023 Fedora Release Engineering - 2.2.0-5 - Rebuilt for https://fedoraproject.org/wiki/Fedora_38_Mass_Rebuild * Mon Sep 26 2022 Jerry James - 2.2.0-4 - Add BR on javapackages-tools for Java arches - Run the Java and python tests * Wed Sep 21 2022 Jerry James - 2.2.0-3 - Initial RPM, from the libstemmer and python-snowballstemmer packages
