striplong
It would be nice if striplong worked, but the example fails when
string.striplong is used in place of string.strip. The log says:
! LuaTeX error [string "\directlua "]:1: attempt to call field
'striplong' (a nil value)
stack traceback:
[string "\directlua "]:1: in main chunk.
Is the format of the call different than shown in the wiki, or is a
different mechanism required to quote a potentially long string?
The name of the function is “strings.striplong”.
This should be “utilities.strings.striplong” but it has no effect
because when take a look
at the saved string in Lua you can see that blank lines are removed
from the text.
Wolfgang
Indeed. This does build without error, but the
utilities.strings.striplong result is worse than the string.strip
result, with some additional whitespace at the end of the test string
from the earlier example.
the definition of 'worse' depends on expectations and given the fact
that in tex a newline or two newlines in a row have a different meaning
it is just a guess what you want to achieve
anyway, the next beta will have
local str = table.concat( {
" ",
" aap",
" noot mies",
" ",
" ",
" zus wim jet",
"zus wim jet",
" zus wim jet",
" ",
}, "\n")
utilities.strings.striplines(str,'prune'):
[[aap
noot mies
zus wim jet
zus wim jet
zus wim jet]]
utilities.strings.striplines(str,'prune and collapse'):
[[aap
noot mies
zus wim jet
zus wim jet
zus wim jet]]
utilities.strings.striplines(str,'prune and no empty'):
[[aap
noot mies
zus wim jet
zus wim jet
zus wim jet]]
utilities.strings.striplines(str,'retain'):
[[
aap
noot mies
zus wim jet
zus wim jet
zus wim jet
]]
utilities.strings.striplines(str,'retain and collapse'):
[[
aap
noot mies
zus wim jet
zus wim jet
zus wim jet
]]
utilities.strings.striplines(str,'retain and no empty'):
[[
aap
noot mies
zus wim jet
zus wim jet
zus wim jet
]]
so you can choose what you like
