The reason + * is that I want to make something coherent in memory (easy to interprete), + * and to let the user type whatever he wants. This part was originally written + * for gabc, that's why it's always talking about it. But it could as well be + * used by other read plugins, to put things in order. + * + * Basically all the following lines of code are made for the last function, + * that will take a "user-written" gregorio_character list into a xml-compliant + * and tex-compliant list. It's more complicated than it seems... + * + * Functionalities: For example if the user types tt<i>ttt<b>ttt</i>tt I want + * it to be represented as tt<i>ttt<b>ttt</b></i><b>tt</b>. The fabulous thing + * is that it is xml-compliant. This part also determines the middle, for + * example pot will be interpreted as p{o}t. When I did that I also thought + * about TeX styles that needed things like {p}{o}{t}, so when the user types + * <i>pot</i>, it is interpreted as <i>p</i>{<i>o</i>}<i>t</i>. + * + * Internal structure: To do so we have a structure, det_style, that will help + * us : it is a stack (double chained list) of the styles that we have seen + * until now. When we encounter a <i>, we push the i style on the stack. If we + * encounter a </i> we suppress the i style from the stack. Let's take a more + * complex example: if we encounter <i><b></i>, the stack will be first null, + * then i then bi, and there we want to end i, but it is not the first style of + * the stack, so we close all the styles that we encounter before we encounter + * i (remember, this is for xml-compliance), so we insert a </b> before the + * </i>. But that's not all, we also write a <b> after the </i>, so that the b + * style continues. There our stack is just b. For center, we just close all + * the styles in the stack, insert a { and reopen all the styles in the stack. + * + * The structure used for character, styles, etc. is described in + * include/struct.h + * + * The functionment in this file is quite simple : we add all the characters + * that we see, even if they are incoherent, in the gregorio_character list, + * and then we call a very complex function that will build a stack of the + * style, determine the middle, make all xml-compliant, mow the lawn, etc. + * + * This code is *really* spaghetti, but I think it's a necessary pain. + * + */ + +/* + * + * This function inserts a style before current_character, updating the double + * chained list. + * + */ + +static void insert_style_before(unsigned char type, + unsigned char style, gregorio_character *current_character) +{ + gregorio_character *element = + (gregorio_character *) gregorio_malloc(sizeof(gregorio_character)); + element->is_character = 0; + element->cos.s.type = type; + element->cos.s.style = style; + element->next_character = current_character; + if (current_character->previous_character) { + current_character->previous_character->next_character = element; + } + element->previous_character = current_character->previous_character; + current_character->previous_character = element; +} + +/* + * + * This function puts a style after current_character, and updates + * current_character to the gregorio_character it created.
