formatting

问题 Referencing the answer in this post I added /Views/Shared/DisplayTemplates and added a partial view called ShortDateTime.cshtml as shown below: @model System.DateTime @Model.ToShortDateString() When the model contains a value this works and the formatted date is displayed correctly: @Html.DisplayFor(modelItem => item.BirthDate, "ShortDateTime") However, if a null value is returned a 'System.InvalidOperationException' is thrown. Indicating: {"The model item passed into the dictionary is null,

问题 I'l looking for an idiomatic (perhaps built-in) way of padding string representations of integers with zeros on the left. In my case the integers are never more than 99 so fix r = if length r == 1 then '0':r else r fix.show <$> [1..15] works. But I expect there is a better way. How do I pad string representations of integers in Haskell? 回答1: printf style formatting is availble via the Text.Printf module: import Text.Printf fmt x = printf "%02d" x Or to special case the formatting of 0: fmt 0

问题 I'm trying to generate a string that involves an occasional float with trailing zeros. This is a MWE of the text string and my attempt at removing them with {0:g} : xn, cod = 'r', 'abc' ccl = [546.3500, 6785.35416] ect = [12.350, 13.643241] text = '${}_{{t}} = {0:g} \pm {0:g}\;{}$'.format(xn, ccl[0], ect[0], cod) print text Unfortunately this returns: ValueError: cannot switch from automatic field numbering to manual field specification This question Using .format() to format a list with

问题 I ran into a problem with the Eclipse formatter. It won't format my code correctly when declaring methods within a class declaration. It puts a new line after the method's return type. I already exported the style xml file and examined the settings in it, but none of the settings have any apparent connection to this problem, and the settings editor in Eclipse didn't show the same problem happening in it's sample code for method declarations. Here is an example bit of code for what I want to

问题 There seems to be a lack of formatting settings for vscode. I want to be able to format html such that my html shows up as: <div attrib1=value1 attrib2=value2 attrib3=value3> Content </div> This is one functionality that I'd really love to have! 回答1: VSCode added a way to do this now. You can edit your settings.json and then add the following for the desired effect: "html.format.wrapAttributes": "force-aligned" --or-- "html.format.wrapAttributes": "force" force-aligned will also add indents

问题 I have a SQLDB with table of field REAL. In my layout I have set its field size to allow only 8+2 digits. In my object I have used the data-type of the field as "float". qs[0] = "CREATE TABLE " + RELATION_TABLE_NAME + "(id TEXT PRIMARY KEY, name TEXT NOT NULL, startBal REAL NOT NULL, currentBal REAL NOT NULL);"; <EditText android:text="" android:id="@+id/relCurrBalTxt" style="@style/EditTextStyle" android:inputType="numberDecimal" android:maxLength="11" android:hint="12345678.99" /> I entered

问题 I have a column of data (A). The data in each cell in column (A) is half one color and half another color. For example, let's say the first portion of the character string is red and the second portion of the character string is black. The length of the red and black character strings within each cell varies with no pattern. The type of characters that are red and black vary with no pattern. There is no space or special character that separates the red characters from the black characters

问题 PSPS: (a Pre-scripted Post-script) It has just come to mind that a more prescient question would have included the notion of: Is this non-display of "0x"(showbase) for zero-value integers a standard behaviour, or is it just a quirk of my MinGW implementation? It all began on a pleasant Sunday morning... I want to dump some Handles in their hex representation, and in a consistant, formatted way. I want a leading 0x and a fixed width , but this is proving to be elusive using the expected stream
