I am generating lexical analyzer with JLEX. I found a regular expression for string literal from this link and used it in .jflex file same of other expressions. but it gives me this error :
unterminated string at the end of the line
StringLiteral = \"(\\.|[^"\\])*\"
can anyone help me please, thanks.
...ANSWER
Answered 2021-Jun-15 at 20:46The regular expression you copied is for (f)lex, which uses a slightly different syntax for regular expressions. In particular, (f)lex treats "
as an ordinary character inside bracketed classes, so [^"\\]
is a character class matching anything other than (^
) a quotation mark ("
) or a backslash (\\
).
However, in JFlex, the "
is a quoting character, whether outside or inside brackets. So the "
in the character class is unterminated. Hence the error message.
So you need to backslash-escape it:
QUESTION
I am trying to have a number of columns with exact widths, and their heights split evenly between some number of elements. For some reason, despite my indicating an exact 200px
width on each column, they are instead getting a computed width of 162px
somehow. Chrome dev tools is showing some weird arrow thing indicating that it it was shrunk from it's intended size for some reason. I've even tried removing all of the content from the div's as possible so as to rule out some weird interaction with the size of children.
The html for the relevant area is this:
...ANSWER
Answered 2021-Jun-15 at 20:20Setting display: flex
turns the sizing of child elements over to the flex container. If you don't want the individual elements to resize, set flex-grow: 0
, flex-shrink: 0
, and flex-basis: 200px
. You can do all three using the flex

QUESTION
I'm currently learning HTML, CSS, and JavaScipt. I'm trying to make a basic project, but I'm having problems with adding a new image on the new card. When I click on the 'add item' button, I create a new card with image. However, when I add another card for the second time, my image from the first card that I created will disappear. Can someone help me on how to fix this solution. Thank you.
...ANSWER
Answered 2021-Jun-15 at 19:05Rather than using two different function, one for adding card image and one for card content, try combining both of them.. here use the code for your reference.
QUESTION
I am a beginner learning from a tutorial on how to change the colour of a selected area of a picture with a range of colour options.
I can figure out how to change one area, but unsure how to implement the other areas.
What I want to achieve is to click on the selected area, it highlights the border (CSS), then change the colour by using the colour options.
What is the best way to implement this? I'm I correct in thinking maybe a switch statement with onclick to select the specific area of the picture?
...ANSWER
Answered 2021-Jun-15 at 11:48You could try having a "select" function run when you click on one of the areas. This function would "highlight" the area (border-color), and save the id of the area in a variable.
Then when you click on the color swatches another function would run that will take the value previously saved id and select the HTML element based on that.
