Parsing input files

When parsing input files, jPicEdt can handle a variety of, say, syntax deviations... I carved it fairly robust :-), and you needn't worry too much about whether your syntax is perfectly LaTeX-, epic- or PsTricks- compliant or not, since jPicEdt will issue a pretty informative message as soon as it finds a syntax error, an incorrect format number, etc... However, we strongly encourage you to follow these rules :

In case you are still fathoming out what those weird comment lines that jPicEdt adds to your file really mean, here are some hints. We rely on this trick for commands that cannot be put on a single line : using a %Begin and %End blocks is a way of making jpicedt understand that every command that lies inside the block belongs to the same graphical element, e.g. a circle, a line,.... Obviously, for graphical elements whose formatted string holds on a single line (which is always the case for PsTricks, so far), there's no need to rely on this trick however.

Note : this small grammar was designed at a time where only the LaTeX picture environment and the epic/eepic package were handled by jPicEdt. Don't expect to find parameters related to colours, shadows or textures ! (please use PsTricks in this case). Only rules needed to properly represent a compound graphical object with the set of graphical attributes offered by the eepic package are part of this grammar, no less, no more...
