Txt2tags Markup Rules %!includeconf: rules.conf This document describes all the details about each txt2tags mark. The target audience are **experienced** users. You may find it useful if you want to master the marks or solve a specific problem about a mark. If you are new to txt2tags or just want to know which are the available marks, please read the [Markup Demo MARKUPDEMO]. Note 1: This document is generated directly from the txt2tags test-suite. All the rules mentioned here are 100% in sync with the current program code. Note 2: A good practice is to consult [the sources rules.t2t] when reading, to see how the texts were made.

All the lines of the paragraph must begin with a TAB. Any non-tabbed line closes the quote block. %%% Nesting: Creating deeper quotes The number of leading TABs identifies the quote block depth. This is quote level 1. With two TABs, we are on the quote level 2. The more TABs, more deep is the quote level. There isn't a limit. %%% Nesting: Reverse nesting works This quote starts at level 4. Then its depth is decreased. Counting down, one by one. Until the level 1. %%% Nesting: Random count Unlike lists, any quote block is independent, not part of a tree. The TAB count don't need to be incremental by one. The nesting don't need to follow any rule. Quotes can be opened and closed in any way. You choose. %%% Nesting: When not supported Some targets (as sgml) don't support the nesting of quotes. There is only one quote level. In this case, no matter how much TABs are used to define the quote block, it always will be level 1. %%% Syntax: Spaces after TAB Spaces AFTER the TAB character are allowed. But be careful, it can be confusing. %%% Invalid: Spaces before TAB Spaces BEFORE the TAB character invalidate the mark. It's not quote. %%% Invalid: Paragraphs inside Paragraph breaks inside a quote aren't possible. This sample are two separated quoted paragraphs, not a quote block with two paragraphs inside. %%% Closing: EOF closes the open block The end of the file (EOF) closes the currently open quote block. = Raw =[raw] See [Verbatim #verbatim], the same rules apply. = Verbatim =[verbatim] %INCLUDED(t2t) starts here: ../../../test/marks/verbatim.t2t BODYINIT %%% Syntax: A single line ``` A verbatim line. %%% Syntax: A single line with leading spaces ``` Another verbatim line, with leading spaces. %%% Syntax: Area (block) ``` A verbatim area delimited by lines with marks. ``` %%% Syntax: Area (block) with trailing spaces ``` Trailing spaces and TABs after the area marks are allowed, but not encouraged nor documented. ``` %%% Invalid: No space between mark and contents ```Not a verbatim line, need one space after mark. %%% Invalid: Leading spaces on block marks ``` Not a verbatim area. The marks must be at the line beginning, no leading spaces. ``` %%% Closing: EOF closes the open block ``` The end of the file (EOF) closes the currently open verbatim area. ``` = Definition List =[deflist] See [List #list], the same rules apply. = Numbered List =[numlist] See [List #list], the same rules apply. = List =[list] %INCLUDED(t2t) starts here: ../../../test/marks/list.t2t BODYINIT %%% Items: Prefixed by hyphen - Use the hyphen to prefix list items. - There must be one space after the hyphen. - The list is closed by two consecutive blank lines. %%% Items: Free leading spacing (indentation) - The list can be indented on the source document. - You can use any number of spaces. - The result will be the same. %%% Items: Vertical spacing between items - Let one blank line between the list items. - It will be maintained on the conversion. - Some targets don't support this behavior. - This one was separated by a line with blanks. You can also put a blank line inside the item contents and it will be preserved. %%% Items: Exactly ONE space after the hyphen -This is not a list (no space) - This is not a list (more than one space) - This is not a list (a TAB instead the space) %%% Items: Catchy cases - - This is a list - + This is a list - : This is a list %%% Nesting: Creating sublists - This is the "mother" list first item. - Here is the second, but inside this item, - there is a sublist, with its own items. - Note that the items of the same sublist - must have the same indentation. - And this can go on, opening sublists. - Just add leading spaces before the - hyphen and sublists will be opened. - The two blank lines closes them all. %%% Nesting: Free leading spacing (indentation) - When nesting lists, the additional spaces are free. - You can add just one, - or many. - What matters is to put more than the previous. - But remember that the other items of the same list - must use the same indentation. %%% Nesting: Maximum depth - There is not a depth limit, - you can go deeper and deeper. - But some targets may have restrictions. - The LaTeX maximum is here, 4 levels. - This one and the following sublists - are moved up to the level 4 - when converting to LaTeX. - On the other targets, - it is just fine - to have a very deep list. %%% Nesting: Reverse doesn't work - Reverse nesting doesn't work. - Because a sublist *must* have a mother list. - It's the list concept, not a txt2tags limitation. - All this sublists will be bumped to mother lists. - At level 1, like this one. %%% Nesting: Going deeper and back %% When nesting back to an upper level, the previous sublist %% is automatically closed. - Level 1 - Level 2 - Level 3 - Level 4 - Level 3 -- (closed Level 4) - Level 2 -- (closed Level 3) - Level 1 -- (closed Level 2) %% More than one list can be closed when nesting back. - Level 1 - Level 2 - Level 3 - Level 4 - Level 1 -- (closed Level 4, Level 3 and Level 2) %%% Nesting: Vertical spacing between lists - Level 1 - Level 2 -- blank BEFORE and AFTER (in) - Level 3 % comment lines are NOT considered blank lines - Level 4 % comment lines are NOT considered blank lines - Level 3 - Level 2 -- blank BEFORE and AFTER (out) - Level 1 - Level 2 -- blank BEFORE (spaces) and AFTER (TAB) - Level 3 %%% Nesting: Messing up %% Be careful when going back on the nesting, %% it must be on a valid level!
