Tioga Commands
ReadTiogaTipTables
Causes Tioga to read its TIP tables again. If your user category is advanced, you can also invoke this operation by selecting in any Tioga document and hitting CTRL-!.
WritePlain
Make Tioga files unformatted by eliminating everything except the plain text. Inserts leading tabs before each node according to its nesting in the tree and terminates each node with a carriage return.
WriteMesaPlain
Same as WritePlain, except inserts double dashes at start of comment nodes.
ReadIndent
Build Tioga files with one node per line of source with indenting based on white space at the start of lines.
TiogaMesa
Convert Mesa files to Tioga format by combining a ReadIndent with a CTRL-M over the entire file.
DoTiogaOps
Expects a command line containing operations in the same format as in the EditTool operations field. Among other things, you can use this to initialize various EditTool choices such as IgnoreCase or MatchWords.
AnnotateProperties
Creates a system button, TiogaProps, to annotate Tioga documents with comments describing the node properties and the document nesting structure. LEFT-click TiogaProps with the selection in a document and the annotations are added; RIGHT-click TiogaProps and the annotations are removed from the selected document.
When a list of file names is given as command arguments, AnnotateProperties writes new versions of the files with the annotations in place.
PruneAnnotations
PruneAnnotations takes a list of files and writes new versions of the files with the annotations removed.
Hyphenation
Starts up hyphenation routines for Tioga. Currently the only hyphenation routine provided uses an explicit list of hyphenation rules on the Tioga node or its ancestor nodes. To use:
1. Execute the "Hyphenation" command to start things up.
2. Using the EditTool, add a node property with the key "HyphenationList" and the value consisting of a list of hyphenations ("-" between syllables, " " between words). This property applies to the node and all its descendants in the Tioga document. The most convenient place to put this property is usually the root, since then it applies to the whole document.
3. Place the style rule
 (List) hyphenation
so that it will be effective on the desired node. (Use a Postfix property, for example).
This step may be omitted; the (List) hyphenation routine is currently also registered as the (English) hyphenation routine, since we don't have a real English routine yet, and Cedar.style is set up to use (English) hyphenation in paragraphs.
4. A hyphenation point may also be marked by using the discretionary hyphen character (357|043); this is used in the word "demonstrate" below, and overrides the rule in the list.
Example:
<<NodeLevel: 4, Format: block, Comment: , HyphenationList: ap-pli-ca-bil-i-ty ex-em-pla-ry demon-strate ma-te-ri-al hy-phen-a-tion tech-niques text-u-al ses-qui-ped-el-i-an , Postfix: 1.65 in lineLength, CharSets: ...>>
Exemplary textual material to dem#onstrate the applicability of hyphenation techniques to sesquipedelian words.
