Subject [jira] Commented: (FELIX-1487) Support for commands on multiple lines
Date Thu, 20 Aug 2009 10:23:14 GMT

    [ https://issues.apache.org/jira/browse/FELIX-1487?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12745374#action_12745374

Guillaume Nodet commented on FELIX-1487:

Doesn't your suggestion falls short as soon as you have a pipe ? Given the pipe takes precedence
over the ';', if you have

echo a
echo b | grep b

I think simply adding a ';' would lead to

<echo a ; echo b> | grep b

instead of the intuitive
echo a ; <echo b | grep b>

Additionally, I think we should try to avoid \ at the end of lines when possible.
I don't think it's a problem for closures, as

each $bundles {
  echo starting bundle $it
  start $it

would be interpreted as

each $bundles { ; echo starting bundle $it ; start $it ; } ;

which should be ok imho.

> I think this is important, especially when writing closures, to be able to split commands
on multiple lines.
> From the shell, it can't be easily leveraged, unless the command line edition also supports
multiline edition, but for script files, it would be really handy.
> My original thinking would be to consider new lines as ';', but this may required changing
the precedence order of | and ;
> The other solution would be add a pseudo grouping operator () on each line in addition
to considering newlines as ';'
