I need to use javaCC to identify the correct syntax from the errors.
< #horario : "<"<hora>":"<minuto>"-"<hora>":"<minuto>">"<retorno> >
< #horarioError : "<" ("()"|"(" (~["<", ">"])+")")? ">"<retorno> >
The first one is the correct syntax and the second one identify tge errors.
An error definition can contain the correct syntax but at least one time the error.
This is what I thought, but it classifies the correct ones as an error:
< error : (<diaSemana>(<horarioError>|<horario>)<retorno>)+<delimitador> >
How can I make to appear at least one time horarioError in any line?
Thanks.
First off I think you are trying to do way too much at the lexical level. I suggest using parsing (BNF) rules for all but the lowest level tokenizing.
To answer the question, you can do the following:
< error : ( <diaSemana>
<horario><retorno>
)*
( <diaSemana>
<horarioError><retorno>
)
( <diaSemana>
(<horarioError>|<horario>)<retorno>
)*
<delimitador>

How does one define constraints via Vapor? Here's my latest attempt:
database.schema(Thingmabob.schema)
.id()
.field("parentID", .uuid, .required, .references(Stuff.schema, .id))
.field("name", .string, .required)
.field("isDocumened", .bool, .required)
.field("value1", .uint, .required)
.field("value2", .uint)
.constraint(.custom("value2 > value1 + 1")) // << "syntax error"
.create()
Solution is two folds:
1) Seems the documentation — HA! — forgot to mention that any field mentionned in the .constraint(.custom( ... )) is set to lowercase. So if you have a field/column like .constraint(.custom("isDocumented ..."), the value in the constraint becomes isdocumented which fails to matches any column. Just beautiful!
2) Also, note that, while I'm using the .constraint() API, the framework has no idea what do to with it... I thus have to write the full statement CHECK notcamelcase > alsonotcamelcase (not just notcamelcase > alsonotcamelcase). Not sure why .constraint() isn't named .arbitrarySQLSegment() as that would've been more accurate and helpful than all that documentation I've read.
i try to run:
x = (1 / 1 – 2)
And here is the message:
Error: unexpected input in "x=(1 / 1 �"
I have the same issue with these sign : <- and * and minus, none of them are recognised.
You might be confronted to the so-called "zero-width space" which is not interpreted as a space. Check this wiki page:
If the blanks you have in your code example are this kind of character, it will make an error like this:
Error: unexpected input in "x=(1 / 1"
as some comments point out, one must be careful when pasting code from websites.
I am trying to run an R loop on an individual based model. This includes two lists referring to grid cells, which I originally ran into difficulties with because they returned the error: Error: (list) object cannot be coerced to type 'double'. I think I have resolved this error by typing "as.numeric(unlist(x))."
Example from code:
List 1:
dredg<-list(c(943,944,945,946,947,948,949...1744,1745))
dredging<-as.numeric(unlist(dredg)). I refer to 'dredging' in my code, not 'dredg.'
List 2:
nodredg<-list(c(612,613,614,615,616,617,618,619,620,621,622,623,624,625,626,627,628,629,630,631))
dcells<-as.numeric(unlist(nodredg)) I refer to 'dcells' in my code, not 'nodredg.'
However, now when I use these two number arrays (if that's what they are) my code returns the error
Error in dcells[[dredging[whichD]]] : subscript out of bounds
I believe this error is referring to the following lines of code:
if(julday>=dstart[whichD] & julday<=dend[whichD] & dredging[whichD]!=0){
whichcells<-which(gridd$inds[gridd$julday==julday] %in% dcells[[ dredging[whichD] ]]) #identify cells where dredging is occurring
}
where:
whichD<-1
julday<-1+day
'dstart=c(1,25,75,100)dend=c(20,60,80,117)`
Here is the full block of code:
for (i in 1:time.steps){
qday <- qday + 1
for (p in 1:pop){
if (is.na(dolphin.q[p,1,i]!=dolphin.q[p,2,i])) {
dolphin.q[p,6,i]<-which.max(c(dolphin.q[p,1,i],dolphin.q[p,2,i]))
}else{
dolphin.q[p,6,i]<-rmulti(c(0.5,0.5))
}
usP<-usage[p,]
if(julday>=dstart[whichD] & julday<=dend[whichD] & dredging[whichD]!=0){
whichcells<-which(gridd$inds[gridd$julday==julday] %in% dcells[[ dredging[whichD] ]])
usP[whichcells]<-0
usP<-usP/sum(usP) #rescale the home range surface to 1
}
I was wondering if anyone could show me what is going wrong? I apologize if this is a very simple mistake I am making, I am a novice learner that has been scouring the internet, manuals, and Stack for days with no luck!
Thanks in advance!
I am trying to build the inline segment to filter the pages (ex. to separate the pages for blogs and games) using the function BuildClassificationValueSegment() to get the data from Adobe Analytics API,
I have tried some thing like
report.data.visits <- QueueTrended(reportsuite.id,date.from,date.to,metrics,elements,
segment.inline = BuildClassificationValueSegment("evar2","blog","OR")).
Got error like :
Error in ApiRequest(body = report.description, func.name = "Report.Validate") :
ERROR: segment_invalid - Segment "evar2" not valid for this company
In addition: Warning message:
In if (segment.inline != "") { :
the condition has length > 1 and only the first element will be used
Please help on the same.Thanks in advance...
I recommend you to declare the InlineSegment in advance and store it in a variable. Then pass it to the QueueTrended function.
I've been using the following syntax to generate an inline segment:
InlineSegment <- list(container=list(type=unbox("hits"),
rules=data.frame(
name=c("Page Name(eVar48)"),
element=c("evar48"),
operator=c("equals"),
value=c(as.character("value1","value2"))
))
You can change the name and element arguments in order to personalize the query.
The next step is to pass the InlineSegment to the QueueRanked function:
Report <- as.data.frame(QueueRanked("reportsuite",
date.from = dateStart,
date.to = dateEnd,
metrics = c("pageviews"),
elements = c("element"),
segment.inline = InlineSegment,
max.attempts=500))
I borrowed that syntax from this thread some time ago: https://github.com/randyzwitch/RSiteCatalyst/issues/129
Please note that there might be easier ways to obtain this kind of report without using InlineSegmentation. Maybe you can use the selected argument from the QueueRanked function in order to narrow down the scope of the report.
Also, I'm purposefully avoiding the BuildClassificationValueSegment function as I found it a bit difficult to understand.
Hope this workaround helps...
I'm trying to read or redirect the test console output. I'm doing an AssertAreEqualIgnoringOrder and I need to parse some of the values within the failures. The failures output looks like this:
Expected elements to be equal but possibly in a different order.
Ensure the list of idols matches with the db
Equal Elements : ["98932", "670945", "6747749", "6770804", "7110604", "13280109", "13280121", "13280149", "14448042", "14448336", "15726213", "17009409", "17245584", "93123", "2212314", "10129661", "13280123", "13280125", "13280135", "13280144", "17245263", "18784003", "1112597", "2885514", "8505390", "13279857", "15032800", "17009391", "17009396", "17009398", "17880635", "18340462", "3606775", "13280116", "13280133", "13280137", "14448341", "15050039", "16711731", "17008920", "17009377", "17009381", "17009402", "17245606", "17901335", "865871", "6029748", "17009372", "17009386", "17009406", "17245604", "19113286", "19865372"]
Excess Elements : ["14419207"]
Missing Elements : ["17241620"]
How can I read this directly or redirect it to a file? If I can just parse the output, I can work it afterwards with some RegEx, that will not be a problem.
Another solution would be to parse the Gallio report file, but I'm sure there is a faster way.
Can you help me, please?
Thanks,
Andrei
