The plugin uses some +heuristics that work well most of the time, but in particular cases you may +want to to override the automatic rules, so that the manually defined +indentation is preserved by commands like `gg=G`. + +This can be achieved by appending `%>`, `%<`, `%=` or `%!` to a line to +explicitly control the indentation of the next line. The `<` and `>` symbols +may be repeated many times: for instance, `%>>` will cause the next line to be +indented twice. Of course, `%<` means that the next line should be +de-indented; `%=` sets the indentation of the next line to be equal to the +indentation of the current line; and `%!` means that the indentation of the +next line should not change from whatever it has been manually set. + +For example, this is the default indentation of a simple macro: +> + def foo = + makepen( + subpath(T-n,t) of r + shifted .5down + --subpath(t,T) of r shifted .5up -- cycle + ) + withcolor black + enddef +< +By adding the special comments, the indentation can be adjusted arbitrarily: +> + def foo = + makepen( + subpath(T-n,t) of r %> + shifted .5down %> + --subpath(t,T) of r shifted .5up -- cycle %<<< + ) + withcolor black + enddef +< + *ft-metapost-commands* +Commands ~ + *:FixBeginfigs* +Renumber beginfig() blocks in the current buffer so that the n-th figure has +number n.
