patch -p0, so there's some issue with that failing. Could you tell me what you see after you do this:comby 'Some(:[x])' ':[x].?' src/test/scala/com/oanda/sfb/rates/CandleExchangeRatesSpec.scala -diff > p.patch
patch -p0 --verbose < p.patch
comby -help | grep stdout, just the comby.dev search

Hello. Quick question: suppose I have a Javascript object with a (Typescript) type like {a: number, b: number, c?: number} (note c is optional). I'd like to extract the props a, b, and c, from the object into an ordered, delimited list. So, some example rewrites might be:
{a: 1, b: 2, c: 3 } -> 1,2,3
{c: 4, b: 5, a: 6} -> 6,5,4 // out of order
{a: 7, b: 8} -> 7,8,, // some items missingIs it possible to achieve this kind of matching and rewriting with Comby? I see there was a merge for optional holes. Perhaps one could use pattern matching + optional holes, but I'm not clever enough to figure it out.
Hello, I am trying to use comby to substitute a template variable with a string fragment.
However, I found that this does not work:
comby '' ':[1~\w] :[2]' -substitute-only '[{"variable":"1", "value":"hello" }]'
While this works:
comby '' ':[1~\w] :[2]' -substitute-only '[{"variable":"1~\w", "value":"hello" }]'
Is there a any work-around for this? Or will I always have to append the associated regex to the template variable

Hey all - LOVE comby. I’m wanting to drop a line of code, but retain indentation, I have in my TOML config:
match='''
:[prefix]@NotNull:[~\s]
'''
rewrite=":[prefix]"but that gives me a warning about matching everything - but works. Is there a better syntax I should be using?

Hey all - trying to use comby to rewrite a 170mb CSV file, worked fine on a small sampe - but the large file just bails due to timeouts. Altho, even updating the -timeout doesn’t help - any other options I could enable to try speed this up ( or even get it to not crash).
Seems I’m gonna need to run this process for the next week or so massaging some data, comby worked well initially but…. 8 matchers - Maybe if I tell it not to run in parrallel or something?

Is -config suppose to accept a directory of TOML files? CSV of directories containing templates, or TOML configuration files is a bit ambiguous over the directory containg “templates or TOML files”, or “directories of templates, OR toml files”.
Directory of TOMLs would be handy but doesn’t seem to work.

Hello everyone!
I am trying to use comby to do some refactor in a large scala codebase.
I have a rule like this:
LegacySelection(TableName(:[table]), :[field]) --> NewSelection(:[table], :[field])The rule works, but the annoying thing is about whitespaces.
Sometimes in the codebase TableName is preceeded by a new line and spaces:
LegacySelection(
TableName("foo"),
"bar"
)sometimes it is inline
LegacySelection(TableName("foo"), "bar")Now, the rules does not match the first one, because in the pattern there is no whitespace. If I put the whitespace it will match the second, but not the first...
How can I avoid to have to replicate the rules with the two versions?
(In reality the rule is much more complex than this, and covering all the cases it is not feasible)

:[m](:[a], :[a]) applied to the code foo(ab, ab)I observed that comby generates an auxiliary variable to represent the second template variable
a. I was wondering two things :(i) is there a way i can get back the original variable name? Is a 37 character prefix always added in such scenarios followed by
_equal in suffix?(ii) I was curious why did you choose to report this auxiliary variable instead of reporting the two occurrences as a list of
range for variable a.
