I started using JavaCC a few days ago.. I am looking for a good tutorial.
how to parse a .dat file?
In my first example the program ask me to enter an expression then says if it's ok or not! but if I want the program to read file then parse it?!
Thank you!
Thank your for your response.
I resolved this problem! a.dat file look likes a text file where I can store some values ...
But I have another problem..
Let me explain my project.
I have a text file of a lot of lines and each one contains 3 or 4 value separate with a space. I have to read this value and overwrite them in another text file. The problem is that the numbers are real of the form 1235.215E6 .. I don't know how to declare such as a variable!

The appearance of "textparcali" in RStudio Source Editor was as follows.
In textparcali (tbl_df), I ran the following code to delete single strings.
textparcali$word<-gsub("\\W*\\b\\w\\b\\W*",'', textparcali$word)
But the deletion was interesting. You can see the picture below. Please note lines 67 and 50.
Everything was fine for line 50 and lines like that. However, this was not the case for line 67 (and I think there are others like it).
I focused on one line(67) to understand why you deleted it wrong. I've already seen what it says on this line in the editor. But I also wanted to look at the console. I wrote the following code to the console.
textparcali$word[67]
The word on line 67 looks different in the console. The value that doesn't appear when you make a copy paste but surprisingly appears on the console:
The reason I put it as a picture is because this character disappears after the copy-paste command.
You can download the file containing this character from the link below. However, you should open it with Notepad ++.
Character.txt
Gsub did his job right. How is that possible? What's the name of this character? When I try to write code that destroys this character, the " sign changes and does not delete.
textparcali$word<-gsub('[[:punct:]]+',' ',textparcali$word) command also does not work.
What is the explanation of my experience? I do not know. Is there a way to destroy this character? What caused this? I ve asked a lot.
Thank you all.
(I apologize for the bad scribbles in the pictures.)
I found the surprise character.
Above Right, Combining Dot ͘ ͘
The following is the code required to eliminate this character.
c<-"surprise character"
c
[1] "\u0358"
textparcali$word<-gsub("\u0358","",textparcali$word,ignore.case = FALSE)
textparcali$word<-gsub("\u307","",textparcali$word,ignore.case = FALSE)
Code 307 did the job for me. However, you should determine what the actual code is. If not, your character code may be incorrect.
More detailed information can be found in the links below.

Thanks a lot!
executing bootstrap validation
Invalid input:
inputs.yaml. inputs must represent a dictionary.
Valid values can either be a path to a YAML file, a string formatted as YAML or a string formatted as key1=value1;key2=value2
How to solve this problem??
Since there are a lot of missing details in your question, I'll try to explain what could be the answer:
You didn't give the right path to the input.yaml file.
The path could be relative to your working directory, or a full path, but either way it must lead to the file.
Your input file is not formatted correctly.
An input.yaml file should include a dictionary of keys and values as in: image: 'redhat_santiago'. Tabs are not allowed, only spaces. All keys should be aligned to the same column.
Please try to check the above, in the future it would be better if you add the input file and the command you are using.
Best,
Jonathan
I am trying to learn text processing units in Unix through hackerrank.com's practice problems.
One of the problems is this: https://www.hackerrank.com/challenges/text-processing-cut-4
But I don't understand how to take inputs from standard output in unix, so I'm having trouble submitting my answer. Can you please let me know how to get started with taking inputs? Thanks
In the question we don't have to take input, we have to just display the first four characters from each line of text.
solution:
cut -c1-4
i know that this is an old question, but I'll answer anyway, so everyone can have a response, if they need it.
As you can read on the man page, the synopsis is cut [OPTION]... [FILE]..., so the FILE argument is optional (because it's surrounded by square brackets).
In addition:
With no FILE, or when FILE is -, read standard input.
So if you simply call cut command withoud any file specification, it will read from STDIN.
I Have Just Gone Through to this Sphinx4 Speech Recognition,I had implemented it with the helloworld demo of sphinx4,

If any one Providing this service with the payment.then even its ok...
Here is an easy website that allows you to do that to create a .dic file: http://www.speech.cs.cmu.edu/tools/lmtool-new.html . Just upload a .txt file with what you would like to add to the dictionary. You can do this multiple times if you have more than a few thousand sentences and then converge them into one file.
I'm trying to parse a file that looks sort of hex encoded but mostly not. I contacted support for the vendor who created the file and they said that they it can be parsed using "an 0x116 offset"
What is a 0x116 offset?
It took me 2 weeks to get an answer from the vendor on my first question, so I wanted to see if someone here could help me make sense of! Thank you!
"0x116 offset" means nothing. It could be a value that needs to be added to words or subtracted to remove some naive encoding, or anything else for that matter.
Could you post a part of the file? Is it binary or text? Could you define "mostly not"?
What vendor/software package/device does this file come from?
