NAME

vlna – adds tilde after each non-syllabic preposition

USAGE

vlna [options] [filenames]

PREFACE

There exists a special Czech and Slovak typographical rule: you cannot leave the non-syllabic preposition on the end of one line and continue writting text on next line. For example, you cannot write down the text "v lese" (in a forest) like "v<new-line>lese". The program vlna adds the asciitilde between such preposition and the next word and removes the space(s) in this place. It means, the program converts "v lese" to "v~lese". You can use this program as a preporcessor before TeXing. Moreower, you can set another sequence to store instead asciitilte (see the -x option).

DESCRIPTION

The program vlna processes one or more files, searches the non-syllabic prepositions followed by space(s) in these files and converts this/these space(s) to asciitilde for each such occurrence.

In the processed file, the activity of the program can be blocked by %~- sequence and the activity can be restored again by the %~+ sequence. These sequences can include spaces, it means that % ~- is a correct sequence too.

The rule to recognize a preposition follows: The arbitrary number of opening parentheses can be written before the preposition and before these (optional) parentheses must be the space, tabelator or new-line. The preposition itself is one-letter word, the letters have to be from this set: {KkSsVvZzOoUuAI}. See the -v option if you want to change this set of letters. From version 1.2, the TeX sequence can be written before preposition and before the brace. Example: "<new-line>([V lese" is converted to "<new-line>([V~lese". Another example: "
