\grabbufferdata
Syntax
| \grabbufferdata[...][...][...] | |
| [...] | name of the buffer to store the text |
| [...] | string where the buffer contents start |
| [...] | string where the buffer contents end |
Description
This is a slightly low-level command to grab user input and store it in a buffer. It is different from \startbuffer[X]..\stopbuffer because it allows one to use custom start and end strings, instead of \startbuffer...\stopbuffer
Example
\setuppapersize[A6] \define\thisisthestart% {\grabbufferdata[mybuffer][thisisthestart][thisistheend]} % If you want to perform some action when the buffer ends % \let\thisistheend{...} \thisisthestart Bent double, like old beggars under sacks, Knock-kneed, coughing like hags, we cursed through sludge, Till on the haunting flares we turned our backs And towards our distant rest began to trudge. \rightaligned{--- Wilfred Owen, excerpt from {\it Dulce et decorum est}} \thisistheend \obeylines \getbuffer[mybuffer]
