3 A: smenu is a selection tool that acts as a filter that takes 'words'
4 from the standard input or a file and presents them on the screen in
5 various arrangements in a scrolling window.
7 A cursor that you can easily move allows you to select one or more
10 The selected 'words' are printed on the standard output.
12 Q: Why smenu tells me: "The length of a 'word' has reached the limit of
13 512 characters." but there is no such 'word' in my entry?
15 A: It is likely that you have an unbalanced single or double quotation
16 mark somewhere. smenu uses quotation marks to be able to have spaces
17 in 'words', and quotation marks that are not used as delimiters must
20 You can use something like: sed -e "s/'/\\\'/g" -e 's/"/\\"/g' to
21 pre-process the input in such a case.
23 Another solution is to ask smenu to treat quotation marks as normal
24 characters by using the -Q|-ignore_quotes option.
26 Q: Why does smenu -C... no longer work?
28 A: smenu uses a new system of options based on the notion of contexts. The
29 -C parameter is only valid in the "Columns" context as indicated in the
32 The string '[-c|-col|-col_mode|-column>Columns]' that is printed
33 in the error message indicates that to switch to "Columns" mode
34 must use the -c parameter or its alternatives.
36 In this case the correct command line should contain something like:
39 Q: How to preserve the original alignment of the columns?
41 A: smenu merges multiple occurrences of word delimiters (' ' in the
42 example below) and so the original alignment of columns is lost.
43 One way to limit this loss is to replace the delimiter with a character
44 that does not appear in the input and is not a delimiter, we will use
45 '!' in the example, and tell smenu to replace it with a space with the
