When in Powershell I can run the following command
.\exiftool.exe '-GPSLatitude*=56.9359839838' '-GPSLongitude*=-4.4651045874' DSC01008.JPG '-overwrite_original_in_place'
This works just fine, and the placement of single quotes around those params are required. I went through various iterations of different placements and the above is the only way I could get it to work.
My issue is -> That I'm trying to replace those values with programmatic values. As in something like the following.
$lat = 56.9359839838
$lon = -4.4651045874
$fileName = 'DSC01008.JPG'
.\exiftool.exe -GPSLatitude*=$lat -GPSLongitude*=$lon $fileName '-overwrite_original_in_place'
I've gone through numerous attempts with single/backtick/double quotes, trying to concatenate and anything else I can think of - but that magic format hasn't appeared!
Any thoughts on what I am doing wrong?
As an example I thought this was really work, yet didn't. But it matches up with the command that does when it's hard coded.
EDIT/Update -
The * are required inside the command, otherwise it doesn't work. They are used to get around not passing in reference locators.
If you were to run these commands in PS, then these are the errors that you get.
cmd ->
.\exiftool.exe "-GPSLatitude*=$lat" "-GPSLongtitude*=$lon" $FileName
error ->
No Error, but the file does not get any GPS tags. Nothing actually modified.
cmd ->
$combLat = "`'-GPSLatitude*=$lat`'" # + "
$combLon = "`'-GPSLongitude*=$lon`'" # + "'"
$combined = "$combLat $combLon $fileName"
# $combined will output the following: '-GPSLatitude*=-3.4651045874' '-GPSLongitude*=55.9359839838' 'E:\CameraAddGPS\TestFolder\DSC01010.JPG'
.\exiftool.exe $combined
error ->
.\exiftool.exe : Wildcards don't work in the directory specification

Update 2 -
This will work, but I do not want to update the image twice.
$combLat = '-GPSLatitude*=' + $lat
$combLon = '-GPSLongitude*=' + $lon
.\exiftool.exe $combLat $fileName '-overwrite_original_in_place'
.\exiftool.exe $combLon $fileName '-overwrite_original_in_place'
The problem is that the latitude and longtitude argumets are "attached" directly to the -GPSLatitute* and -GPSLongtitude* parameter names after the = sign. (The - initial character prevents PowerShell from invoking variable expansion - see GitHub issue #14587.)
One way to work around this is to wrap the -GPSLatitude* and -GPSLongtitude* parameters in " quotes; e.g.
.\exiftool.exe "-GPSLatitude*=$lat" "-GPSLongtitude*=$lon" $FileName -overwrite_original_in_place
Another way is to prefix the - character with a backquote (`); e.g.:
.\exiftool.exe `-GPSLatitude*=$lat `-GPSLongitude*=$lon $fileName -overwrite_original_in_place
I prefer the first variation as it seems more readable to me.
Aside #1: There's no need for the single ' quotes around that last parameter. They don't hurt, but they don't do anything, either.
Aside #2: You can see the actual command line that PowerShell is running if you prefix your command with the getargs command available here:
https://github.com/Bill-Stewart/getargs/releases
The getargs utility outputs the actual command line without any parsing or interpretation and will show the actual command that PowerShell will run.
Since Python v3, format is the primary API method to make variable substitutions and value formatting. However, Odoo is still using the Python 2 approach with the %s wildcard.
message = _('Scheduled meeting with %s') % invitee.name
# VS
message = 'Scheduled meeting with {}'.format(invitee.name) # this is not translated
I have seen some parts of the Odoo code where they have used some workaround, isolating strings.
exc = MissingError(
_("Record does not exist or has been deleted.")
+ '\n\n({} {}, {} {})'.format(_('Records:'), (self - existing).ids[:6], _('User:'), self._uid)
)
But, does anybody know if there is a more convenient way to use the format method and make it work with translations?
_ return a string, so you can call format on it directly.
_("{} Sequence").format(sec.code)
or like this:
_("{code} Sequence").format(code=invitee.code)
when you export the translation in PO file you should see this for the second example:
# for FR translation you should not translate the special format expression
msgid "{code} Sequence"
msgstr "{code} Séquence"
and this for the first example:
msgid "{} Sequence"
msgstr "{} Séquence"
If you don't see this then Odoo must be checking that _() must not be followed by . so you can work around this by doing this for example by surrounding the expression by parentheses :
# I think + "" is not needed
( _("{} Séquence") + "").format(sec.code)
Because In python "this {}".format("expression") is the same as this ("this {}").format("expression")

The problem is in the line 20-23 where:
DTSTART;TZID=/freeassociation.sourceforge.net/Asia/Kolkata:
20171019T000000
DUE;TZID=/freeassociation.sourceforge.net/Asia/Kolkata:20171030T000000
So, the DTSTART's time is in the next line while the DUE's timestamp is in the same line. Hence, a simple python function like:
if line.startswith("DTSTART;TZID"):
line = next(finp)
dt = line.strip()[0:8]
wont work for both. This one won't works for DUE, and I have to make another function without next for that purpose.
How can I handle any such date/time etc irrespective of the linebreak?
Maybe using regex would be useful in your case,
try this:
import re
if line.startswith("DTSTART;TZID"):
line = next(finp)
dt = re.search('(.*)T.*', line).groups(1)
if line.startswith("DTSTART;TZID"):
dt = re.search('.*\:(.*)T.*', line).groups(1)
The first group that's wrapped in () is in both cases the datestamp.
To decipher the regex; .* matches anything until the explictly named character occurs, which is in the first scenario 'T' because of the newline and the "plain" string given to us. In the second the stamp is between ':' and 'T' which enclose the date.
Using String-Slicing could become difficult when you are not sure if the city is always Kolkata etc.
Looking for right way to detect one keyword during board boot up message.
After keyword detected, send Enter key after one second.
Kernel is Linux.
# Serial port inisialisation is finished here.
# Read boot message
($count, $result) = $ob->read(300); # at least 300 chars coming till keyword appear
if ($result =~ m/Booting_up/) {
print "send Enter ...\n";
sleep 1;
$ob->write("\r\n");
}
Thanks for hint
It appears that you are using Win32::SerialPort module, or perhaps Device::SerialPort which
provides an object-based user interface essentially identical to the one provided by the Win32::SerialPort module.
Its method read takes the number of bytes to read and returns the number read and writes them into the given string.
You may be "missing" the phrase because it's past the 300-mark, and your code doesn't read any further. Try to loop, getting a few bytes at a time and adding them up, thus building the string in small reads.
my bytes_in = 10; # length of pattern, but it does NOT ensure anything
my ($read, $result);
while (1)
{
my ($count, $read) = $ob->read( $bytes_in );
$result = $result . $read;
if ($result =~ m/Booting_up/) { # is it "Booting_up" or "Booting up" ?
print "send Enter ...\n";
sleep 1; # is this needed?
$ob->write("\r\n");
# last; # in case this is all you need to do
}
last if $count != $bytes_in; # done reading
}
I don't put the $ob->read statement in the loop condition since the documentation isn't crystal clear on how the method works. You may also be able to simply use
while ( my ($count, $read) = $ob->read( $bytes_in ) ) {
$result = $result . $read;
if ($result =~ m/Booting_up/s) {
# ...
}
last if $count != $bytes_in;
}
We read a small number of bytes at a time to prevent problems with either polling or blocking reads, brought up in comments by BenPen. See Configuration and capability methods.
You can first read those first 300 bytes that precede the pattern in one go and then start reading a few (or one) at a time, which would also lead to the quickest identification of the phrase.
This can be tweaked further but let's first see what it does as it stands (I cannot test).
Documentation also offers a few other methods which may be useful, in particular readline and streamline. As this is all rather low level there are yet other ways but if you got all else working perhaps this will be enough to complete it.
Perhaps rather index the string?
($count, $result) = $ob->read(300); # at least 300 chars coming till keyword appear
$substring = 'Booting_up';
if (index($result, $substring) != -1) {
print "send Enter ..\n";
sleep 1;
$ob->write("\r\n");
}
I have a large number of text files (1000+) each containing an article from an academic journal. Unfortunately each article's file also contains a "stub" from the end of the previous article (at the beginning) and from the beginning of the next article (at the end).
I need to remove these stubs in preparation for running a frequency analysis on the articles because the stubs constitute duplicate data.
There is no simple field that marks the beginning and end of each article in all cases. However, the duplicate text does seem to formatted the same and on the same line in both cases.
A script that compared each file to the next file and then removed 1 copy of the duplicate text would be perfect. This seems like it would be a pretty common issue when programming so I am surprised that I haven't been able to find anything that does this.
The file names sort in order, so a script that compares each file to the next sequentially should work. E.G.
bul_9_5_181.txt
bul_9_5_186.txt
are two articles, one starting on page 181 and the other on page 186. Both of these articles are included bellow.
There is two volumes of test data located at [http://drop.io/fdsayre][1]
Note: I am an academic doing content analysis of old journal articles for a project in the history of psychology. I am no programmer, but I do have 10+ years experience with linux and can usually figure things out as I go.
Thanks for your help

AFFECTIVE PHENOMENA — EXPERIMENTAL
BY PROFESSOR JOHN F. .SHEPARD
University of Michigan
Three articles have appeared from the Leipzig laboratory during the year. Drozynski (2) objects to the use of gustatory and olfactory stimuli in the study of organic reactions with feelings, because of the disturbance of breathing that may be involved. He uses rhythmical auditory stimuli, and finds that when given at different rates and in various groupings, they are accompanied by characteristic feelings in each subject. He records the chest breathing, and curves from a sphygmograph and a water plethysmograph. Each experiment began with a normal record, then the stimulus was given, and this was followed by a contrast stimulus; lastly, another normal was taken. The length and depth of breathing were measured (no time line was recorded), and the relation of length of inspiration to length of expiration was determined. The length and height of the pulsebeats were also measured. Tabular summaries are given of the number of times the author finds each quantity to have been increased or decreased during a reaction period with each type of feeling. The feeling state accompanying a given rhythm is always complex, but the result is referred to that dimension which seemed to be dominant. Only a few disconnected extracts from normal and reaction periods are reproduced from the records. The author states that excitement gives increase in the rate and depth of breathing, in the inspiration-expiration ratio, and in the rate and size of pulse. There are undulations in the arm volume. In so far as the effect is quieting, it causes decrease in rate and depth of

It looks like a much simpler solution would actually work.
No one seems to be using the information provided by the filenames. If you do make use of this information, you may not have to do any comparisons between files to identify the area of overlap. Whoever wrote the OCR probably put some thought into this problem.
The last number in the file name tells you what the starting page number for that file is. This page number appears on a line by itself in the file as well. It also looks like this line is preceded and followed by blank lines. Therefore for a given file you should be able to look at the name of the next file in the sequence and determine the page number at which you should start removing text. Since this page number appears in your file just look for a line that contains only this number (preceded and followed by blank lines) and delete that line and everything after. The last file in the sequence can be left alone.
Here's an outline for an algorithm
choose a file; call it: file1
look at the filename of the next file; call it: file2
extract the page number from the filename of file2; call it: pageNumber
scan the contents of file1 until you find a line that contains only pageNumber
make sure this line is preceded and followed by a blank line.
remove this line and everything after
move on to the next file in the sequence
You should probably try something like this (I've now tested it on the sample data you provided):
#!/usr/bin/ruby
class A_splitter
Title = /^[A-Z]+[^a-z]*$/
Byline = /^BY /
Number = /^\d*$/
Blank_line = /^ *$/
attr_accessor :recent_lines,:in_references,:source_glob,:destination_path,:seen_in_last_file
def initialize(src_glob,dst_path=nil)
#recent_lines = []
#seen_in_last_file = {}
#in_references = false
#source_glob = src_glob
#destination_path = dst_path
#destination = STDOUT
#buffer = []
split_em
end
def split_here
if destination_path
#destination.close if #destination
#destination = nil
else
print "------------SPLIT HERE------------\n"
end
print recent_lines.shift
#in_references = false
end
def at_page_break
((recent_lines[0] =~ Title and recent_lines[1] =~ Blank_line and recent_lines[2] =~ Number) or
(recent_lines[0] =~ Number and recent_lines[1] =~ Blank_line and recent_lines[2] =~ Title))
end
def print(*args)
(#destination || #buffer) << args
end
def split_em
Dir.glob(source_glob).sort.each { |filename|
if destination_path
#destination.close if #destination
#destination = File.open(File.join(#destination_path,filename),'w')
print #buffer
#buffer.clear
end
in_header = true
File.foreach(filename) { |line|
line.gsub!(/\f/,'')
if in_header and seen_in_last_file[line]
#skip it
else
seen_in_last_file.clear if in_header
in_header = false
recent_lines << line
seen_in_last_file[line] = true
end
3.times {recent_lines.shift} if at_page_break
if recent_lines[0] =~ Title and recent_lines[1] =~ Byline
split_here
elsif in_references and recent_lines[0] =~ Title and recent_lines[0] !~ /\d/
split_here
elsif recent_lines.length > 4
#in_references ||= recent_lines[0] =~ /^REFERENCES *$/
print recent_lines.shift
end
}
}
print recent_lines
#destination.close if #destination
end
end
A_splitter.new('bul_*_*_*.txt','test_dir')
Basically, run through the files in order, and within each file run through the lines in order, omitting from each file the lines that were present in the preceding file and printing the rest to STDOUT (from which it can be piped) unless a destination director is specified (called 'test_dir' in the example see the last line) in which case files are created in the specified directory with the same name as the file which contained the bulk of their contents.
It also removes the page-break sections (journal title, author, and page number).
It does two split tests:
a test on the title/byline pair
a test on the first title-line after a reference section
(it should be obvious how to add tests for additional split-points).
Retained for posterity:
If you don't specify a destination directory it simply puts a split-here line in the output stream at the split point. This should make it easier for testing (you can just less the output) and when you want them in individual files just pipe it to csplit (e.g. with
csplit -f abstracts - '---SPLIT HERE---' '{*}'
or something) to cut it up.
Here's is the beginning of another possible solution in Perl (It works as is but could probably be made more sophisticated if needed). It sounds as if all you are concerned about is removing duplicates across the corpus and don't really care if the last part of one article is in the file for the next one as long as it isn't duplicated anywhere. If so, this solution will strip out the duplicate lines leaving only one copy of any given line in the set of files as a whole.
You can either just run the file in the directory containing the text files with no argument or alternately specify a file name containing the list of files you want to process in the order you want them processed. I recommend the latter as your file names (at least in the sample files you provided) do not naturally list out in order when using simple commands like ls on the command line or glob in the Perl script. Thus it won't necessarily compare the correct files to one another as it just runs down the list (entered or generated by the glob command). If you specify the list, you can guarantee that they will be processed in the correct order and it doesn't take that long to set it up properly.
The script simply opens two files and makes note of the first three lines of the second file. It then opens a new output file (original file name + '.new') for the first file and writes out all the lines from the first file into the new output file until it finds the first three lines of the second file. There is an off chance that there are not three lines from the second file in the last one but in all the files I spot checked that seemed to be the case because of the journal name header and page numbers. One line definitely wasn't enough as the journal title was often the first line and that would cut things off early.
I should also note that the last file in your list of files entered will not be processed (i.e. have a new file created based off of it) as it will not be changed by this process.
Here's the script:
#!/usr/bin/perl
use strict;
my #files;
my $count = #ARGV;
if ($count>0){
open (IN, "$ARGV[0]");
#files = <IN>;
close (IN);
} else {
#files = glob "bul_*.txt";
}
$count = #files;
print "Processing $count files.\n";
my $lastFile="";
foreach(#files){
if ($lastFile ne ""){
print "Processing $_\n";
open (FILEB,"$_");
my #fileBLines = <FILEB>;
close (FILEB);
my $line0 = $fileBLines[0];
if ($line0 =~ /\(/ || $line0 =~ /\)/){
$line0 =~ s/\(/\\\(/;
$line0 =~ s/\)/\\\)/;
}
my $line1 = $fileBLines[1];
my $line2 = $fileBLines[2];
open (FILEA,"$lastFile");
my #fileALines = <FILEA>;
close (FILEA);
my $newName = "$lastFile.new";
open (OUT, ">$newName");
my $i=0;
my $done = 0;
while ($done != 1 and $i < #fileALines){
if ($fileALines[$i] =~ /$line0/
&& $fileALines[$i+1] == $line1
&& $fileALines[$i+2] == $line2) {
$done=1;
} else {
print OUT $fileALines[$i];
$i++;
}
}
close (OUT);
}
$lastFile = $_;
}
EDIT: Added a check for parenthesis in the first line that goes into the regex check for duplicity later on and if found escapes them so that they don't mess up the duplicity check.
You have a nontrivial problem. It is easy to write code to find the duplicate text at the end of file 1 and the beginning of file 2. But you don't want to delete the duplicate text---you want to split it where the second article begins. Getting the split right might be tricky---one marker is the all caps, another is the BY at the start of the next line.
It would have helped to have examples from consecutive files, but the script below works on one test case. Before trying this code, back up all your files. The code overwrites existing files.
The implementation is in Lua.
The algorithm is roughly:
Ignore blank lines at the end of file 1 and the start of file 2.
Find a long sequence of lines common to end of file 1 and start of file 2.
This works by trying a sequence of 40 lines, then 39, and so on
Remove sequence from both files and call it overlap.
Split overlap at title
Append first part of overlap to file1; prepend second part to file2.
Overwrite contents of files with lists of lines.
Here's the code:
#!/usr/bin/env lua
local ext = arg[1] == '-xxx' and '.xxx' or ''
if #ext > 0 then table.remove(arg, 1) end
local function lines(filename)
local l = { }

assert(#l > 0, "No lines in file " .. filename)
return l
end
local function write_lines(filename, lines)
local f = assert(io.open(filename .. ext, 'w'))
for i = 1, #lines do
f:write(lines[i], '\n')
end
f:close()

Are the stubs identical to the end of the previous file? Or different line endings/OCR mistakes?
Is there a way to discern an article's beginning? Maybe an indented abstract? Then you could go through each file and discard everything before the first and after (including) the second title.
Are the titles & author always on a single line? And does that line always contain the word "BY" in uppercase? If so, you can probably do a fair job withn awk, using those criteria as the begin/end marker.
Edit: I really don't think that using diff is going to work as it is a tool for comparing broadly similar files. Your files are (from diff's point of view) actually completely different - I think it will get out of sync immediately. But then, I'm not a diff guru :-)
A quick stab at it, assuming that the stub is strictly identical in both files:
#!/usr/bin/perl
use strict;
use List::MoreUtils qw/ indexes all pairwise /;
my #files = #ARGV;
my #previous_text;
for my $filename ( #files ) {
open my $in_fh, '<', $filename or die;
open my $out_fh, '>', $filename.'.clean' or die;
my #lines = <$in_fh>;
print $out_fh destub( \#previous_text, #lines );
#previous_text = #lines;
}
sub destub {
my #previous = #{ shift() };
my #lines = #_;
my #potential_stubs = indexes { $_ eq $lines[0] } #previous;
for my $i ( #potential_stubs ) {
# check if the two documents overlap for that index
my #p = #previous[ $i.. $#previous ];
my #l = #lines[ 0..$#previous-$i ];
return #lines[ $#previous-$i + 1 .. $#lines ]
if all { $_ } pairwise { $a eq $b } #p, #l;
}
# no stub detected
return #lines;
}
