[REBOL] Re: adding line hints when building blocks

Hi Gregg,
I've got close to what you want by using a "do string" to create a
template for your files. This at least means you only have to do a
string once. ie...
---8<---
rebol []
template: do "[^/none[^/value none^/mail none^/]^/]"
file: []
insert file copy/deep template
file/1: 'item-1
file/2/2: 1
file/2/4: [foo--bar--com]
insert file copy/deep template
file/1: 'item-2
file/2/2: 2
file/2/4: [foo--baz--com]
insert file copy/deep template
file/1: 'item-3
file/2/2: 3
file/2/4: [foo--bat--com]
sort/skip file 2 ; (;
print mold file
---8<---
This gives...
>> do %test.r
[item-1 [
value 1
mail [foo--bar--com]
] item-2 [
value 2
mail [foo--baz--com]
] item-3 [
value 3
mail [foo--bat--com]
]]
It's not quite perfect as line-hints for the item values are lost when
you change them, ((because they're in the outer block, perhaps?), but
the others are kept so it's almost how you wanted it. This is how
the file would look with no values changed...
>> blk: [] loop 3 [insert blk copy/deep template] print mold blk
[
none [
value none
mail none
]
none [
value none
mail none
]
none [
value none
mail none
]]
So close. Grrr! (: Hope that gets you some way to where you want,
anyway.
Carl.
