At the bottom, I have a general solution to replace lines in a file. But first, here is the answer to the specific question at hand. Helper function: public static void replaceSelected(String replaceWith, String type) { try { // input the file content to the StringBuffer “input” BufferedReader file = new BufferedReader(new FileReader(“notes.txt”)); StringBuffer inputBuffer … Read more
Here is the working example: <div style=”float:left;”> <span style=”display:inline; color: red;”>First Span</span> <span style=”display:inline; color: blue;”>Second Span</span> </div>
One can achieve the effect of anti aliasing very cheaply using vertices with opacity 0. Here’s an image example to explain: Comparison with AA: You can read a paper about this here: http://research.microsoft.com/en-us/um/people/hoppe/overdraw.pdf You could do something along this way: // Colors is a pointer to unsigned bytes (4 per color). // Should alternate in … Read more
Use tac, so you dont have to read the whole file: tac FILE |egrep -m 1 .
you mentioned “entire line” , so i assumed mystring is the entire line. if “token” in mystring: print(mystring) however if you want to just get “token qwerty”, >>> mystring=””” … qwertyuiop … asdfghjkl … … zxcvbnm … token qwerty … … asdfghjklñ … “”” >>> for item in mystring.split(“\n”): … if “token” in item: … … Read more
Because I routinely work with many-gigabyte files, looping through as mentioned in the answers didn’t work for me. The solution I use: with open(sys.argv[1], “r+”, encoding = “utf-8”) as file: # Move the pointer (similar to a cursor in a text editor) to the end of the file file.seek(0, os.SEEK_END) # This code means the … Read more
with open(<FILE>) as FileObj: for lines in FileObj: print lines # or do some other thing with the line… will read one line at the time to memory, and close the file when done…
You are looking for “spans”: Spans (line-type annotations) have a single dimension (width or height) and extend to the edge of the plot area. Please, take a look at http://docs.bokeh.org/en/latest/docs/user_guide/basic/annotations.html#spans So, the code will look like: import numpy as np import bokeh.plotting as bk from bokeh.models import Span p = bk.figure() # Vertical line vline … Read more
Swift 4 @IBOutlet var dashedView: UIView! func drawDottedLine(start p0: CGPoint, end p1: CGPoint, view: UIView) { let shapeLayer = CAShapeLayer() shapeLayer.strokeColor = UIColor.lightGray.cgColor shapeLayer.lineWidth = 1 shapeLayer.lineDashPattern = [7, 3] // 7 is the length of dash, 3 is length of the gap. let path = CGMutablePath() path.addLines(between: [p0, p1]) shapeLayer.path = path view.layer.addSublayer(shapeLayer) } … Read more
You can slice off the last character: read_line = read_line[:len(read_line)-1] Perhaps a better approach is to use the strings library: read_line = strings.TrimSuffix(read_line, “\n”)
