I am trying to load an Arff file that represents letters in binary, it looks like this: http://pastebin.com/zKSr2YJi
But when I try to load it into Weka, I ge the error "nominal value not decalared in header, read Token[A], line 33.
From what I understand from this, the 'A' at the end of the first data line isn't the same as the 'A' in the #attribute class line. But they look the same? I tried adding single quotes, still nothing.
Fixed it by copy-pasting the 'A' from the #attribute class line.
This can also be because of trailing paces from this item.
Opening the data file in excel and saving in csv format removes extra whitespace. Renamed he file as a .data and Weka was able to open.

I would like to create a User Snipper in VS Code that is a combination of variables and plaint text. This can typically be achieved by combining variables and plain text with a whitespace between then. But I would like to ad a variable next to a text without a whitespace.
For Example, I would like to create the current timestamp like this:
2022-02-19T21:02:24-0530
Below is what I tried
$CURRENT_YEAR-$CURRENT_MONTH-$CURRENT_DATET$CURRENT_HOUR:$CURRENT_MINUTE:$CURRENT_SECOND-0530
Notice the T in between $CURRENT_DATE & $CURRENT_HOUR
OUTPUT:
2022-02-CURRENT_DATET21:06:12-0530
You can add $ symbol before the plain-text you want to add.
In this case, you need at add $T instead of T
$CURRENT_YEAR-$CURRENT_MONTH-$CURRENT_DATE$T$CURRENT_HOUR:$CURRENT_MINUTE:$CURRENT_SECOND-0530
Note that $T will get considered as a placeholder, and it will be the last item selected while tabbing through the inserted snippet.
In a file called foo.fxml in ${basedir} there is a section that reads
<!-- ANT SEARCH HERE 5 -->
where 5 may be any integer.
How can I get an ant property to hold the value of that integer, in this case, 5?
There's two steps to this. First, you need to read the file, which you can do with LoadFile. Then you can use a regular expression to get the number in the comment. Ant-Contrib has PropertyRegex which is good for this.
I am trying to create a Sublime Text snippet for AngularJs. This snippet should expand to AngularJs controller (or service, etc or any ng component). In the resulting code, it should construct the controller name in camelCase from the hyphenated file name.
For example:
when I type the snippets strings, say, ngctrl in an empty file called employee-benefits-controller.js, it should expand as given below:
angular.module('').controller('EmployeeBenefitsController', ['', function(){
}]);
I am trying to use the $TM_FILENAME variable by applying a regex on it to achieve this conversion. If anyone has already done this, please let us know.
You could use something like this:
<snippet>
<content><![CDATA[
angular.module('${1:moduleName}').controller('${TM_FILENAME/(^|-|\.js)(.?)|/\U\2\E/g}', ['', function(){
${2://functionCode}
}]);
]]></content>
<tabTrigger>ngctrl</tabTrigger>
</snippet>
Notes:
Note 1: maybe you want to change the scope so that the snippet its only triggered in javascript context.
Note 2: I'm not familiar with angularjs, so I don't know its naming conventions (I have supposed that an uppercase letter its needed after a hyphen [-] character and at the begining of the name, but I don't know if a uppercase character its needed after a dot character for example). So, you'll probablly have to adapt the snippet.
Note 3: expression explained:
${TM_FILENAME/(^|-|.js)(.?)/\U\2\E/g}
TM_FILENAME its the var_name item
(^|-|.js)(.?) its the regex (the parts of the variable we select).
\U\2\E its the format_string (how we format what we have selected).
g its the options (g means globally, so every time something its selected the format its given).
TM_FILENAME: the file name with the extension included.
\U => init uppercase conversion. \E => finish uppercase conversion. \2 => second group, i.e. second parénthesis, (.?), its a single char or an empty string.
(^|-|.js)(.?) First we look for the beginning of the word (^), or for a hypen character (-), or for the extension (.js).
(.?) Then we select in a parenthesis group (second group) the character (if any) after that hypen (or at the beginning of the word or after the extension).
Finally we use the uppercase conversion over that selected character as explained. Note that as there is not character after the extension, we are simply removing the extension from the output.
Note 4: as you probablly know, using ${1:moduleName} and ${2://functionCode} allows you to quickly move (using tab) and edit the important parts of the snippet once it has been triggered, such as the module or the function code.
I am trying to add a special character (specifically the ndash) to a Model field's help_text. I'm using it in the Form output so I tried what seemed intuitive for the HTML:
help_text='2 – 30 characters'
Then I tried:
help_text='2 \2013 30 characters'
Still no luck. Thoughts?
django escapes all html by default. try wrapping your string in mark_safe
You almost had it on your second try. First you need to declare the string as Unicode by prefacing it with a u. Second, you wrote the codepoint wrong. It needs a preface as well; like \u.
help_text=u'2\u201330 characters'
Now it will work and has the added benefit of not polluting the string with HTML character entities. Remember that field value could be used elsewhere, not just in the Form display output. This tip is universal for using Unicode characters in Python.
Further reading:
Unicode literals in Python, which mentions other codepoint prefaces (\x and \U)
PEP263 has simple instructions for using actual raw Unicode characters in a source file.
extJS didnt see too big text with many <\br>'s..
If i write text something like "lalal lalalal lsadsdhas afjhjhj";
Its okei, works.
If i write text with \n (<\br>) something like:
"hello,
my name
is Polly!";
ExtJS didnt see those lines. How i can avoid this?
Thank you!
This is because Javascript doesn't allow multi-line strings. If you want a linebreak in your string, it has to be coded with an escape sequence like '\r\n'. So,
alert("hello, \r\nmy name\r\nis Polly!");
will display as 3 lines. If the string is going into an html element, then insert '<br />' in place of the '\r\n'.
finally, if you need a long string with lots of blank spaces between the words, for some reason, you can either keep typing on the same line, or break it up into several lines and combine the lines with the '+' operator, like this:
var longstring =
'hello \r\n'
+'my name \r\n'
+'is Polly!';
