text-files

问题 I have asked a related question in the past and I know how to read the file thanks to the help of the experts here. Now I have a new problem. I first read the data from the file like so: fid = fopen('D:\file.txt', 'rt'); a = textscan(fid, '%s %f %f %f %f %f %f', ... 'Delimiter',',', 'CollectOutput',1, 'HeaderLines',1); fclose(fid); I then process the file and change a few values of the column. Now I want to write a new file newfile.txt in the exact same format as my file.txt with the new

问题 I have been trying to do this with no luck so I've decided to ask SO. I have a page with a bunch of different buttons and each button has it own parameters. I want to create a .txt file as a log and then every time someone clicks on one of the buttons write in the log with the parameters and the button that was clicked. Each button has its own function so I'm assuming I would just create the function and then add it at the beginning of each function using the function's parameters. So I would

问题 I'm trying to extract some data from an Arduino over the usb-serial-port and to write it into a txt-file. Therefore i'm using a batch-file (Windows 7, ordinary cmd), which sends e.g. a "d" to request the desired data from the Arduino. Having received the "d", the Arduino starts to send the data to the pc. The batch-file reads the data and writes it to some txt-file. The batch code is: mode COM4 BAUD=9600 PARITY=n DATA=8 echo d >COM4 COPY COM4 data.txt That works so far, but the problem is:

问题 1.I need to convert a PDF File into a txt.file.

问题 Is it possible to host, instead of a web app, a HTML file with NGROK? I really don't know anything about NGROK, I just used it to host a server for a Twilio app, and am wanting to use it to host a HTML file for another one of my projects. Also, anybody know how to create a HTML file on a Mac? Thanks in advance. Or, If I can't use NGROK, anybody know something as easy and free is it is that I could use for hosting a HTML file on my computer. I need to be able to change the file in real time,

问题 I've got a file whose format I'm altering via a python script. I have several camel cased strings in this file where I just want to insert a single space before the capital letter - so "WordWordWord" becomes "Word Word Word". My limited regex experience just stalled out on me - can someone think of a decent regex to do this, or (better yet) is there a more pythonic way to do this that I'm missing? 回答1: You could try: >>> re.sub(r"(\w)([A-Z])", r"\1 \2", "WordWordWord") 'Word Word Word' 回答2:

问题 I just got a source code file from a friend. The file was created in UNIX. When I opened it in Windows using NotePad++, each line had one extra blank line. Puzzled, I downloaded Vim and used it to open the file. I then saw a bunch of ^M at the end of each line. What is this ^M? How do you prevent it from being inserted? 回答1: Those are DOS/Windows-style line-endings (to be pedantic that's what they're commonly known as now but most early non-UNIX OSes like CP/M and OS/2 had them as well). On

问题 I have a text file that I want to read in and put each line from the file into its own string.

问题 The code I am running is in /Test1/Example . If I need to read a .txt file in /Test1 how do I get Java to go back 1 level in the directory tree, and then read my .txt file I have searched/googled and have not been able to find a way to read files in a different location.
