This describes an experimental mode for lttoolbox-java which was made in december 2010 but never brought into use.
The idea is to add 'flag' symbols that must match in the lttoolbox expansion.
Given the symbols
<sdef n="mi:1" /> <sdef n="mi:0" /> <sdef n="bi:0" /> <sdef n="bi:1" />
A given expansion will be pruned away if there are conflicting flag symbols. For example an expansion with both <mi:1> and <mi:0> will be pruned awway.
A <mi:1> and <bi:0> won't be pruned away as these flags doesen't conflict.
Here is an example:
<pardef n="prefix"> <!-- 'bi-' is the prefix for indicative --> <e> <p><l>bi</l> <r><s n="bi:1"/></r></p></e> <!-- 'mi-' is the prefix for subjunctive --> <e> <p><l>mi</l> <r><s n="mi:1"/></r></p></e> <e> <p><l></l> <r><s n="xp:1"/></r></p></e> </pardef> <pardef n="khoda/n__vblex"> <e> <p><l>m</l> <r>n<s n="xp:0"/><s n="mi:1"/><s n="bi:0"/><s n="vblex"/><s n="pri"/><s n="p1"/><s n="sg"/></r></p></e> <e> <p><l>m</l> <r>n<s n="xp:0"/><s n="mi:0"/><s n="bi:1"/><s n="vblex"/><s n="prs"/><s n="p1"/><s n="sg"/></r></p></e> <e> <p><l>š</l> <r>n<s n="xp:0"/><s n="mi:1"/><s n="bi:0"/><s n="vblex"/><s n="pri"/><s n="p2"/><s n="sg"/></r></p></e> <e> <p><l>š</l> <r>n<s n="xp:0"/><s n="mi:0"/><s n="bi:1"/><s n="vblex"/><s n="prs"/><s n="p2"/><s n="sg"/></r></p></e> <e> <p><l></l> <r>n<s n="xp:0"/><s n="mi:1"/><s n="bi:0"/><s n="vblex"/><s n="pri"/><s n="p3"/><s n="sg"/></r></p></e> <e> <p><l></l> <r>n<s n="xp:0"/><s n="mi:0"/><s n="bi:1"/><s n="vblex"/><s n="prs"/><s n="p3"/><s n="sg"/></r></p></e> <e> <p><l>n</l> <r>n<s n="xp:1"/><s n="vblex"/><s n="inf"/></r></p></e> </pardef>
Now, if the 2 pardefs are combined in, say
<e lm="khodan"> <par n="prefix"/><i>khoda</i><par n="khoda/n__vblex"/></e>
we don't get all the 3x7 possibilites because conflicting flags are ruled out.
Effectively we get only:
bikhodam:<bi:1>khodan<mi:0><xp:0><vblex><pri><p1><sg> bikhodaš:<bi:1>khodan<mi:0><xp:0><vblex><pri><p2><sg> bikhoda:<bi:1>khodan<mi:0><xp:0><vblex><pri><p3><sg> mikhodam:<mi:1>khodan<bi:0><xp:0><vblex><prs><p1><sg> mikhodaš:<mi:1>khodan<bi:0><xp:0><vblex><prs><p2><sg> mikhoda:<mi:1>khodan<bi:0><xp:0><vblex><prs><p3><sg> khodan:<xp:1>khodan<xp:1><bi:0><mi:0><vblex><inf>
The lttoolbox-java processor automatically removes flag symbols from the output, so in the end we get just
bikhodam:khodan<vblex><prs><p1><sg> bikhodaš:khodan<vblex><prs><p2><sg> bikhoda:khodan<vblex><prs><p3><sg> mikhodam:khodan<vblex><pri><p1><sg> mikhodaš:khodan<vblex><pri><p2><sg> mikhoda:khodan<vblex><pri><p3><sg> khodan:khodan<vblex><inf>
Usage[edit]
Here are the relevant flags for lttoolbox-java processor.
$ lt-proc-j -f: match flags (experimental) -S: show hidden control symbols (for flagmatch and compounding)
