Opening Japanese-named files in Lua - file
I have bunch of XML files named in Japanese. I use Lua to read them and put the necessary informations into tables. I could open files named only in a single kanji like 名.xml, but for multiple kanjis like 名前.xml it was contrawise. Before I ran the Lua file, I set the command line's code page to 65001 (as UTF-8). And to read the files I need to encode the filename using WinAPI library from ACP (ASCII code page?) to UTF-8, but this encoding only works for the single kanjis. I've tried several suggestions across internet, using short path to the file, etc. but none of them worked. I tried to use the short path by running Lua as administrator--as stated in other similar question that you need administrator previleges to use the short path--but no luck.
...
for fn in io.popen("DIR xml /B /AA"):lines() do
...
local f = assert(io.open("xml\\" .. winapi.encode(winapi.CP_UTF8, winapi.CP_ACP, fn), "rb"))
...
end
...
But my code produced "Invalid argument" error. I searched this error but none of them are Lua-related, so I opened the C/C++-related ones, but what I got was only 'use _wfopen' or something like that. It's not implemented in Lua and neither I want to implement it myself. So anyone have any idea how to solve this? For more information just be sure to let me know. Thanks!
I don't know why your program does not work, but try this workaround:
local pipe = io.popen([[for %G in (xml\*) do #(type "%G" & echo #FILENAMEMARKER#%G)]], "rb")
local all_files = pipe:read"*a"
pipe:close()
for filecontent, filename in all_files:gmatch"(.-)#FILENAMEMARKER#(.-)\r?\n" do
-- process your file here
print('===== This is your file name:')
print(filename)
print('== This is your file content:')
print(filecontent)
print('== End of file')
end
I think you can use the Japanese alphabet in a table like
local jaAlphbet={"一","｜","丶","ノ","乙","亅","<","二","亠","人","⺅","𠆢","儿","入","ハ","丷","冂","冖","冫","几","凵","刀","⺉","力","勹","匕","匚","十","卜","卩","厂","厶","又","マ","九","ユ","乃","𠂉","⻌","口","囗","土","士","夂","夕","大","女","子","宀","寸","小","⺌","尢","尸","屮","山","川","巛","工","已","巾","干","幺","广","廴,"廾","弋","弓","ヨ","彑","彡","彳","⺖","⺘","⺡","⺨","⺾","⻏","⻖","也","亡","及","久","⺹","心","戈","戸","手","支","攵","文","斗","斤","方","无","日","曰","月","木","欠","止","歹","殳","比","毛","氏","气","水","火","⺣","爪","父","爻","爿","片","牛","犬","⺭","王","元","井","勿","尤","五","屯","巴","毋","玄","瓦","甘","生","用","田","疋","疒","癶","白","皮","皿","目","矛","矢","石","示","禸","禾","穴","立","⻂","世","巨","冊","母","⺲","牙","瓜","竹","米","糸","缶","羊","羽","而","耒","耳","聿","肉","自","至","臼","舌","舟","艮","色","虍","虫","血","行","衣","西","臣","見","角","言","谷","豆","豕","豸","貝","赤","走","足","身","車","辛","辰","酉","釆","里","舛","麦","金","長","門","隶","隹","雨","青","非","奄","岡","免","斉","面","革","韭","音","頁","風","飛","食","首","香","品","馬","骨","高","髟","鬥","鬯","鬲","鬼","竜","韋","魚","鳥","鹵","鹿","麻","亀","啇","黄","黒","黍","黹","無","歯","黽","鼎","鼓","鼠","鼻","齊","龠"}
print(jaAlphbet[1])--and you can call the letters, letter by letter

Trouble with running words through text files and counting them
Python 3+ This is the error i get This is my code I want the user to input some words, then the program should run each word through my two textfiles, if the word exists in any of them, I want the program to add +1 to the positive/negative count list. Thank you for your help :)
Seems like you have stumbled upon a Decoding error when trying to open one of the input files in the wordlist function. it is usually hard to determine the encoding used for a particular file. so you could :
1.Try opening the file with a different encoding such as ISO-8859-15,etc.
def OpenFile():
try:
with open("My File.txt",mode="r",encoding="IS0-8859-15")
#do process My File
except UnicodeDecodeError:
print("Something went Wrong Try a different file encoding")
else:
#everything was okay, return the required
finally:
# clean up here
2. Look it modules that try and determine the correct encoding for the file such as the chardet module
Install the
chardet module :
sudo pip3 install chardet
you can run it at the command line with your file as the Argument to determine the encoding
cd /path/to/File/
chardetect My\ File.txt
this should return the likely encoding for the given file
3.You can use the chardet module inside your python code however this is recommended in a case where you will be opening a file you do not have access to e.g at a clients computer whom wants to open another specified file
and reopening the same file and redetecting the encoding will cause your program to be slow.
First of all positive_count and negative_count should be integers and not lists. If you wish to count, adding 1 to the list isn't really what you're trying to accomplish. Second of all, the UnicodeDecodeError is there because the encoding of the underlying file is not utf-8. Did you try utf-16 or utf-16-le? In case you're using Windows, utf-16-le is probably the encoding used unless you're using code-points in which case guessing will be a nightmare.
A old text file with special format
I am working on HP-UX project, there are a old document. Can open it with vim, but there are some special character among text. For example: .P "xxxxx" .AL 1 10 .LI "xxx" .H 3 "xxxx" It looks like html but not be html. Is it possible convert it to modern document?
Looks like troff. Install GNU troff (Groff) and try: groff -Thtml -pet -mm input.mm > output.html
I guess more details are needed - some ideas you may try: First, issue a file command for the file. It will probably tell you what type of file is. jim#debian:~$ file foo.bar foo.bar: ASCII text Second, search for similar files and see if there's a program to open them in the machine - maybe, they are binary files for some program out there, and you just don't know which one. Last, but not least, I believe you are right - looks like HTML code to me, so maybe this is used by an application as a kind-of intermediate language, that is parsed later to transform it to real HTML. I hope this helps!
Opening a .hs file with ghci in Terminal?
I'm using Mountain Lion. I open the terminal, then I load ghci, I write :l and then I try to load my file (which is in my desktop) by dragging it with the mouse from my desktop to the terminal, so I know that the location is correct and I get this, thank you in advance: Prelude> :l /Users/myusername/Desktop/Test.hs [1 of 1] Compiling Main ( /Users/myusername/Desktop/Test.hs, interpreted ) /Users/myusername/Desktop/Test.hs:1:7: parse error on input `\' Failed, modules loaded: none. Prelude> Edit: The file Im trying to open (written in Text Edit) is: double :: Int -> Int double x = x + x
TextEdit is not a plaintext editor (unlike e.g. Windows Notepad), so by default it will include formatting junk in your files that GHC obviously isn't happy about. Apparently you can still use TextEdit if set up correctly, but it's quite recommendable to use a proper programming editor. Like any Unix, OSX comes with a vi flavour, which takes some time to get used to but isn't that hard and works fine; at least you can use it to check what's really in your file. vi /Users/myusername/Desktop/Test.hs or, even simpler cat /Users/myusername/Desktop/Test.hs will just give you the exact contents of your file. For the choice what editor to use best, consider this question.
I tried the same procedure on Windows and it worked perfectly. Have you tried to go to the directory inside GHCi and open it? The procedure would be: Prelude> :cd /Users/myusername/Desktop/ Prelude> :l Test.hs For me, copying/pasting the code you have posted, both situations worked on Windows.
The presence of a \ implies you've got an RTF (rich text) file from TextEdit. RTF is TextEdit's default, and it's a format that annotates plain text with information about text font, size, etc. I'd recommend vi or emacs, but to fix your immediate problem, open the file in TextEdit and hit Cmd-Shift-t to convert your file to plain text.
Tcl determine file name from browser upload
I have run into a problem in one of my Tcl scripts where I am uploading a file from a Windows computer to a Unix server. I would like to get just the original file name from the Windows file and save the new file with the same name. The problem is that [file tail windows_file_name] does not work, it returns the whole file name like "c:\temp\dog.jpg" instead of just "dog.jpg". File tail works correctly on a Unix file name "/usr/tmp/dog.jpg", so for some reason it is not detecting that the file is in Windows format. However Tcl on my Windows computer works correctly for either name format. I am using Tcl 8.4.18, so maybe it is too old? Is there another trick to get it to split correctly? Thanks
The problem here is that on Windows, both \ and / are valid path separators so long Windows API is concerned (even though only \ is deemed to be "official" on Windows). On the other hand, in POSIX, the only valid path separator is /, and the only two bytes which can't appear in a pathname component are / and \0 (a byte with value 0).
Hence, on a POSIX system, "C:\foo\bar.baz" is a perfectly valid short filename, and running
file normalize {C:\foo\bar.baz}
would yield /path/to/current/dir/C:\foo\bar.baz. By the same logic, [file tail $short_filename] is the same as $short_filename.
The solution is to either do what Glenn Jackman proposed or to somehow pass the short name from the browser via some other means (some JS bound to an appropriate file entry?). Also you could attempt to detect the user's OS from the User-Agent header.
To make Glenn's idea more agnostic to user's platform, you could go like this:
Scan the file name for "/".
If none found, do set fname [string map {\\ /} $fname] then go to the next step.
Use [file tail $fn] to extract the tail name.
It's not very bullet-proof, but supposedly better than nothing.
You could always do [lindex [split $windows_file_name \\] end]
C - Reading multiple files
just had a general question about how to approach a certain problem I'm facing. I'm fairly new to C so bear with me here. Say I have a folder with 1000+ text files, the files are not named in any kind of numbered order, but they are alphabetical. For my problem I have files of stock data, each file is named after the company's respective ticker. I want to write a program that will open each file, read the data find the historical low and compare it to the current price and calculate the percent change, and then print it. Searching and calculating are not a problem, the problem is getting the program to go through and open each file. The only way I can see to attack this is to create a text file containing all of the ticker symbols, having the program read that into an array and then run a loop that first opens the first filename in the array, perform the calculations, print the output, close the file, then loop back around moving to the second element (the next ticker symbol) in the array. This would be fairly simple to set up (I think) but I'd really like to avoid typing out over a thousand file names into a text file. Is there a better way to approach this? Not really asking for code ( unless there is some amazing function in c that will do this for me ;) ), just some advice from more experienced C programmers. Thanks :) Edit: This is on Linux, sorry I forgot to metion that!
Under Linux/Unix (BSD, OS X, POSIX, etc.) you can use opendir / readdir to go through the directory structure. No need to generate static files that need to be updated, when the file system has the information you want. If you only want a sub-set of stocks at a given time, then using glob would be quicker, there is also scandir. I don't know what Win32 (Windows / Platform SDK) functions are called, if you are developing using Visual C++ as your C compiler. Searching MSDN Library should help you.
Assuming you're running on linux... ls /path/to/text/files > names.txt is exactly what you want.
opendir(); on linux. http://linux.die.net/man/3/opendir Exemple : http://snippets.dzone.com/posts/show/5734
In pseudo code it would look like this, I cannot define the code as I'm not 100% sure if this is the correct approach... for each directory entry scan the filename extract the ticker name from the filename open the file read the data create a record consisting of the filename, data..... close the file add the record to a list/array... > sort the list/array into alphabetical order based on the ticker name in the filename... You could vary it slightly if you wish, scan the filenames in the directory entries and sort them first by building a record with the filenames first, then go back to the start of the list/array and open each one individually reading the data and putting it into the record then.... Hope this helps, best regards, Tom.
There are no functions in standard C that have any notion of a "directory". You will need to use some kind of platform-specific function to do this. For some examples, take a look at this post from Cprogrammnig.com. Personally, I prefer using the opendir()/readdir() approach as shown in the second example. It works natively under Linux and also on Windows if you are using Cygwin.
Approach 1) I would just have a specific directory in which I have ONLY these files containing the ticker data and nothing else. I would then use the C readdir API to list all files in the directory and iterate over each one performing the data processing that you require. Which ticker the file applies to is determined only by the filename. Pros: Easy to code Cons: It really depends where the files are stored and where they come from. Approach 2) Change the file format so the ticker files start with a magic code identifying that this is a ticker file, and a string containing the name. As before use readdir to iterate through all files in the folder and open each file, ensure that the magic number is set and read the ticker name from the file, and process the data as before Pros: More flexible than before. Filename needn't reflect name of ticker Cons: Harder to code, file format may be fixed.
but I'd really like to avoid typing out over a thousand file names into a text file. Is there a better way to approach this? I have solved the exact same problem a while back, albeit for personal uses :) What I did was to use the OS shell commands to generate a list of those files and redirected the output to a text file and had my program run through them.
On UNIX, there's the handy glob function:
glob_t results;
memset(&results, 0, sizeof(results));
glob("*.txt", 0, NULL, &results);
for (i = 0; i < results.gl_pathc; i++)
printf("%s\n", results.gl_pathv[i]);
globfree(&results);
On Linux or a related system, you could use the fts library. It's designed for traversing file hierarchies: man fts, or even something as simple as readdir If on Windows, you can use their Directory Management API's. More specifically, the FindFirstFile function, used with wildcards, in conjunction with FindNextFile
