Debugging the wt2html mode

On Linux I have to do:

$ echo "foo bar
> This is a [[link]]" | node parse --trace peg
0-[peg]        | ---->   ["foo bar"]
0-[peg]        | ---->   [{"type":"NlTk","dataAttribs":{"tsr":[7,8]}}]
0-[peg]        | ---->   ["This is a ",{"type":"SelfclosingTagTk","name":"wikilink","attribs":[{"k":"href","v":["link"],"vsrc":"link"}],"dataAttribs":{"tsr":[18,26],"src":"[[link]]"}}]
0-[peg]        | ---->   [{"type":"NlTk","dataAttribs":{"tsr":[26,27]}}]
0-[peg]        | ---->   [{"type":"EOFTk"}]

in order to get the correct output, otherwise, I get:

$ echo "foo bar\nThis is a [[link]]" | node parse --trace peg
0-[peg]        | ---->   ["foo bar\\nThis is a ",{"type":"SelfclosingTagTk","name":"wikilink","attribs":[{"k":"href","v":["link"],"vsrc":"link"}],"dataAttribs":{"tsr":[19,27],"src":"[[link]]"}}]
0-[peg]        | ---->   [{"type":"NlTk","dataAttribs":{"tsr":[27,28]}}]
0-[peg]        | ---->   [{"type":"EOFTk"}]

Probably adding the '-e' option would be perfect:

$ echo -e "foo bar\nThis is a [[link]]" | node parse --trace peg
0-[peg]        | ---->   ["foo bar"]
0-[peg]        | ---->   [{"type":"NlTk","dataAttribs":{"tsr":[7,8]}}]
0-[peg]        | ---->   ["This is a ",{"type":"SelfclosingTagTk","name":"wikilink","attribs":[{"k":"href","v":["link"],"vsrc":"link"}],"dataAttribs":{"tsr":[18,26],"src":"[[link]]"}}]
0-[peg]        | ---->   [{"type":"NlTk","dataAttribs":{"tsr":[26,27]}}]
0-[peg]        | ---->   [{"type":"EOFTk"}]

Looking around, it seems that the POSIX echo doesn't accept the '-e' argument. In fact, the standard bash shell doesn't seem to be standard according to the POSIX echo. We have to use tcsh to run your tests.

$ tcsh
$ echo  "foo bar\nThis is a [[link]]" | node parse --trace peg
0-[peg]        | ---->   ["foo bar"]
0-[peg]        | ---->   [{"type":"NlTk","dataAttribs":{"tsr":[7,8]}}]
0-[peg]        | ---->   ["This is a ",{"type":"SelfclosingTagTk","name":"wikilink","attribs":[{"k":"href","v":["link"],"vsrc":"link"}],"dataAttribs":{"tsr":[18,26],"src":"[[link]]"}}]
0-[peg]        | ---->   [{"type":"NlTk","dataAttribs":{"tsr":[26,27]}}]
0-[peg]        | ---->   [{"type":"EOFTk"}]
