Mac App Bundling

HfstTokenizer can be compiled together with OmegaT and bundled into Mac App. Follow these instructions:

1. Download OmegaT 3.x source code, not 4.x here
2. Get appbundler used by OmegaT from here. This needs Java 1.7
   • install this into ~/.ant/lib/
   • this appbundler needs JavaAppLauncher and jre-mac-root to be defined in OMEGAT_ASSETS_DIR folder, which is searched from environmental variables. If not found in this folder the build process looks one folder down from where you installed OmegaT sources.
     • jre-mac-root is a soft link to the folder where Java Runtime libraries are found
3. Download thread safe version of hfst lookup library and put it to OMEGAT_SRC_FOLDER/lib where OMEGAT_SRC_FOLDER is the folder you just installed the OmegaT source files. here 1- Copy HfstTokenizer.java and HfstStemFilter.java to OMEGAT_SRC_FOLDER/src/org/omegat/tokenizer where OMEGAT_SRC_FOLDER is the folder you just installed the OmegaT source files. - Modify files package name if needed - Remove throws IOException from getTokenStream method and correct StandardTokenizer constructor call - diff HfstTokenizer.java against 4.x HfstTokenizer.java (see diffs below)
4. Add hfst-ol.jar to manifest-template.mf (details below)
5. Add lib/hfst-ol.jar entry to manifest.mf’s Class-Path variable
6. run ant mac in OmegaT source folder, the one where you installed OmegaT
