I want the headings of my GRID should be in capital letters.
If I am using
headers='fieldname:capitalize',
as one of the argument in grid its not working.
Please need expert opinion.
Thanks in advance!
The 'fieldname:capitalize' notation works only with SQLTABLE, not SQLFORM.grid. Also, that simply capitalizes the first letter of the field name, not all the letters. If you want all caps headers in the grid, you could do something like:
grid = SQLFORM.grid(db.mytable,
headers={str(f):f.name.upper() for f in db.mytable})
Note, if you don't provide a headers argument, the grid simply uses the .label attribute of each field in the header, so you can also define the .label attributes in all caps. To do that automatically, you could do:
for field in db.mytable:
field.label = field.name.upper()

I am consuming data from the list and some list may contain multiple line data, so how that can be reflected in the vaadin grid at runtime.
This is the code
public Grid GridBasic() {
grid.removeAllColumns();
grid.addColumn(TopicConsumedDetails::getPartitionNumber).setHeader("PARTITION ");
grid.addColumn(TopicConsumedDetails::getOffset).setHeader("OFFSET");
grid.addColumn(TopicConsumedDetails::getMessage).setHeader("MESSAGE");
grid.setItems(details);
grid.addThemeVariants(GridVariant.LUMO_WRAP_CELL_CONTENT);
grid.getColumns().forEach( col -> col.setAutoWidth(true));
return grid;
}
This just displays all the data in a single line and it requires scrolling left to right.
Vaadin Version :23.3.1
Use the built-in "wrap cell content" variant: https://vaadin.com/docs/latest/components/grid/#wrap-cell-content
grid.addThemeVariants(GridVariant.LUMO_WRAP_CELL_CONTENT);
As per the previous answer, I think that using this is the correct approach:
grid.addThemeVariants(GridVariant.LUMO_WRAP_CELL_CONTENT);
However, you are overriding this setting by calling
grid.getColumns().forEach( col -> col.setAutoWidth(true));
According to the documentation, this automatically sets the column width based on the contents, leading to the right scroll problem.
If you remove this call, you should get the proper wrapping behavior. I was able to reproduce the problem and then see a result like this once I removed the auto width setting:
Alternatively, if you have sensible line breaks in the content you want to wrap, you can do that--but it won't happen automatically, as mentioned by #Rolf in a comment above. That is because the line breaks in the text are basically just whitespace and aren't respected as such by the HTML. So in order to do that, one option is to add an "Html" component column. You can then replace your text's line breaks with <br/> tags, which you could do with a regular expression. It would look like this:
String myColumnText = colText.replaceAll(....); //Some regex to match on your particular line breaks
grid.addComponentColumn(item -> new Html("<p>" + myColumnText +"</p>");
The <p> tags (or some wrapper tags) are required as the Html component requires a wrapper tag.
Note that (1) using this approach means that you won't get the automatic wrapping behavior any more so the line breaks in your source need to be sensible and (2) you have to be certain you trust the incoming content or it is otherwise sanitized, as this kind of rendering-text-as-html opens up some security holes with untrusted content.
In R Markdown, to make a text bold, we just need to do:
**code**
The the word code shows in bold.
I was wondering if there is a way to create a new command, let's say:
***code***
That would make the text highlighted?
Thanks!
It is not easily possible to create new markup, but one can change the way existing markup commands are rendered. Text enclosed by three stars is interpreted as emphasized strong emphasis. So one has to change that interpretation and change it to something else. One way to do so is via pandoc Lua filters. We just have to match on pandoc's internal representation of emphasized strong text and convert it to whatever we want:
function Strong (strong)
-- if this contains only one element, and if that element
-- is emphasized text, convert it to highlighted text.
local element = #strong.content == 1 and strong.content[1]
if element and element.t == 'Emph' then
table.insert(element.content, 1, pandoc.RawInline('html', '<mark>'))
table.insert(element.content, pandoc.RawInline('html', '</mark>'))
return element.content
end
end
The above works for HTML output. One would have to define what "highlighted text" means for each targeted format.
See this and this question for other approaches to the problem, and for details of how to use the filter with R Markdown.
I am currently working on a data sat which has two header rows (The first one acting as overall category description and the second one containing subcategories. And it happens to be that both contain various <text> intervals. For example:
In the first row (column names of the data frame), i have a cell that contains:
- text... <span style=\"text-decoration: underline;\">in the office</span> on the activities below. Total must add up to 100%. <br /><br />
The second row contains multiple cells with:
- text <strong>
- text </strong>
Now, I was able to work out of how to remove all <text> intervals in the second row through:
data[1,] = gsub("<.*>", "", data[1,])
However, for the column names row, if I use:
colnames(data) = gsub("<.*>", "",colnames(data))
I end up just with "text", which I don't want. Due to the fact, that I still want to have:
text... in the office on the activities below. Total must add up to 100%
If some one would have an idea of how to solve it. I would really appreciate it.
Thanks!
You can get what you need by changing the regular expression you are using with the following:
colnames(data) <- gsub("<[^>]+>", "",colnames(data))
This will remove anything between opening and closing tags (including the tag). That should give you what you want.
Your current regex is greedy and is consuming everything in between the first opening bracket and last closing bracket. One quick fix would be to make your regex non greedy by using ?:
data[1,] = gsub("<.*?>", "", data[1,])
Note that using regex to parse HTML generally is not a good idea. If you plan on doing anything with nested content then you should consider using an R package which can parse HTML content.
Demo
I have a certain input string in this form: "[3] [4] at [5]"
From the following datatable, I need to replace the text on the datatable corresponding to the column index inside the bracket.
The output should be: "15A Circuit Breaker #348901836 at 19-Afalcon St. Capitol Subdivision"
Right now, I am using Regex.Replace() method but it searches for a particular pattern. My problem is the integers (corresponding the column index) enclosed inside the brackets is dynamic.
What would be the best way to achieve this?
String.Format should do it for you. Both the format string and the arguments can be easily implemented dynamically.

All of the syntax, and a decent example of what you wish to do are on the linked page.
Sample text =
legacycard.ashx?save=false&iNo=3&No=555
Sample pattern =
^legacycard.ashx(.*)No=(\d+)
Want to grab group #2 value of "555" (the value of "No=" in the sample text)
In Expresso, this works, but in ASP.NET UrlRewrite, it is not catching.
Am I missing something?
Thanks!
I would do something along these lines:
^legacycard.ashx\?(?:.+&)*No=(\d+)
The \? will escape the question mark that normally separates the URL and the parameters, then you make sure that it will capture every parameter key/value pair (anything that ends on &) before the parameter you actually care about. Using ?: lets you specify that the set of brackets is non capturing (I'm assuming you won't need any of the data, has the potential to slightly speeds up your regex) and leaves you just 555 captured. The added benefit of this approach is that it'll work regardless of parameter order.
Just use this regex:
^legacycard\.ashx\?save=(false|true)&iNo=(?<ino>\d+)&No=(?<no>\d+)
Then Regex Replace with
${no}
Looks fine to me, your regex should match the entire string
legacycard.ashx?save=false&iNo=3&No=555
not sure why you have groups, but groups should also return
?save=false&iNo=3&
and
555
For good measure you should know that the . in legacycard.ashx is also interpreted by regex and you would normally escape it, in this case it dosen't matter because a single dot matches everything, also a dot. :)
Try this
^legacycard.ashx(\?No=|.*?&No=)(\d+)
this should work.
