LaTeX: Avoid new paragraph?
latex, layout, paragraph, spacing
Solution
I have to agree with everybody else that you should probably just add the `%`, but I do find this question interesting. The problem is that as soon as LaTeX reads the empty line, it gets converted into the `\par` command, which ends the previous paragraph. At the beginning of `\todo`, that `\par` command has already been executed, and it's impossible to undo it (I think). So your only hope is to keep that `\par` from being inserted or from behaving like it normally does. If you want to prevent it from being inserted, you could try reading Chapter 8 of "The TeXbook", which should tell you how an empty line is converted to `\par`. Alternatively, you could try to make a solution based on the following kind of idea:
Some text.{\let\par\relax
\todo{make note}}
But watch out! You definitely don't want to globally change the behavior of `\par`, which is why I added an extra pair of curly braces (LaTeX commands are scoped, so the new definition of `\par` only takes effect within the group where the definition was made). Good luck.
Problem
I use the `\todo` command from the `\todonotes` package. I'd like to layout my source to put `\todos` separately from the previous paragraph: ``` Some text. \todo{make note} ``` But I don't want `\todo` to start a new paragraph, or it screws up the spacing of the document. Is there a command to avoid this? If there were a command/package to consume the whitespace up to it, then I could redefine `\todo` to use it. Edit: Adding a % between everything is obviously very irritating. Anything else?
