I looked for an applescript to extract the DOI from a PDF file, but could not find it. There is enough information available on the actual format of the DOI (i.e. the regular expression), but how could I use this to get the identifier from the PDF file?
(It would be no problem if some external program were used, such as Hazel.)
If you're ok with using an app, I'd recommend Skim. Good AppleScript support. I'd probably structure it like this (especially if the document might be large):
set DOIFound to false
tell application "Skim"
set pp to pages of document 1
repeat with p in pp
set t to text of p
--look for DOI and set DOIFound to true
if DOIFound then exit repeat--if it's not found then use url?
end repeat
end tell
I'm assuming a DOI would always exist on one page (not spread out to between two). Looks like they are invariably (?) on the first page of an article, which would make this quick of course, even with a large doc.
[edit]
Another way would be to get the Xpdf OSX binaries from http://www.foolabs.com/xpdf/download.html and use pdftotext in the command line (just tested this; it works well) and parse the text using AppleScript. If you want to stay in AppleScript, you can do something like:
do shell script "path/to/pdftotext 'path/to/pdf/file.pdf'"
which would output a file in the same directory with a txt file extension -- you parse that for DOI.
Have you tried it with pdfgrep? It works really well in commmandline
pdfgrep -n --max-count 1 --include "*.pdf" "DOI"
i have no idea to build an apple script though, but i would be interested in one also. so that if i drop a pdf into that folder it just automatically extracts the DOI and renames the file with the DOI in the filename.

I migrated my notes from evernote to markdown files with yarle. unfortunately it created me a lot of folders seperatively for the attachments (although I set it up for one folder only).
I moved all attachements to one folder, so the filepath to the attachments in the mardown files needs to be updated.
I think regex would be right for this, but I don't have any knowledge about regex and would be really thankful for help.
Filepaths are as follows:![[./_attachmentsMove/Coordination_Patterns.resources/CoordinationPattern_Ipsi.MOV]]
All filepaths are identical ![[./_attachmentsMove/]] up to this
The second folder varies e.g. Coordination_Patterns.resources/.
I want to delete everything but the filename.extension itself e.g. ![[CoordinationPattern_Ipsi.MOV]].
An example of the other filepaths:
![[./_attachmentsMove/Jonglieren_(Hände).resources/07 Jonglieren.MOV]]
(second folder changes, filename changes, I also have .png and .mov).
I use MassReplaceIt (app for mac) which allows me to replace expressions in documents with regex. If someone has a solution using the terminal/commandline, I'll try this as well of course :)
Try if this regexp suffices:
(?<=!\[\[)[^\]]+/(?=[^\]/]+]])
Replace with empty string.
It should delete the part from the ![[ up to the last / before the next ]].
We can search files in windows 7 or higher version using the following tool:
(I don't have image uploading privilage. I mean the top-right area in windows file explorer.)
When I search for MATLAB files using "*.m", it not only returns *.m files, but also returns *.mp3, *.mp4 files. Is there any way to show *.m files exclusively?
Thanks!
I assume you used the quotation marks here to show the text you typed, because ironically the exact way how it should work is to put the search in quotation marks...
so
*.m
finds .mp3 as well as .m but
"*.m"
should only find the .m files. Alternatively you could also write
ext:".m"
which would guarantee that only extensions are searched. (Although I am not sure if this is ever necessary here, because while windows can have a dot in the filename and also can have files without extensions I am not sure if it is possible to have both at the same time.)
using the following
"*.m"
will solve your problem.You can find more information on regex to be used in msdn in the following link .Advanced query syntax
Above that, you can also take advantage of the wildcard character *.
For example, if you want to search for a file with a name ending with 024 or starting with 024 then you can put in the search box like *024.* or 024*.* respectively.
Here the * after . represents files with any extensions, if you want particular then mention extension line 024.png.
Explorer don't have a function of finding with RegEx.
You need to use Power-Shell instead of Win Explorer;
for example: where '(?i)Out' is a regex
Get-ChildItem -Path e:\temp -Recurse -File | Where-Object { $_.Name -match '(?i)Out' }
alternatively you can just simply search for your extension like this:
.extension
eg:
typing .exe will give you all the files with .exe extensions in a folder.
PS: Typing .xml OR .vmcx will give you both type of files. It is useful if you seek to make an archive of different kinds of files stored in different folders or locations.
You can get close to proper regex support from the mostly awesome Cygwin, and as a bonus you get most every linux tool running natively on linux. But it still doesnn't know that .* means "zero or more of anything", ^ means the start of a line (and $ the end), so some things are still weird.
And a startlingly large bunch of weird corner cases that only deranged perl programmers notice fail the test.
So many other things it gets wrong, but it's more workable than anything in any windows OS, plus you get perl, grep, diff, wget, curl, etc. -- the whole GNU lib for free.
If you want a full on bash shell with proper respect for regex, install the super neet-o Bash for Windows 10
Either will do what you want. And they're a billion times faster than that stupid search bar that takes off at 100 mph then crawls to 1 pixel per 10 minutes near the end.
I spent most of yesterday putting together a collection of regular expressions to convert all my image names and paths to lower case. Today, I processed a folder full of files and was surprised to discover that many image names are still capitalized.
So I decided to try it one step at a time, first renaming .jpg's, then .gif's, .png's, etc.
I'm working on a Mac, using Dreamweaver and TextWrangler as my text editors. The following regex works perfectly for jpg's, with one major flaw - it deletes the extension...
([\w/-]+)\.jpe?g
\L\1
In other words, it changes South-America.jpg to south-america.
How can I change it so that it retains the file extension? I assume I can then just change it to...
([\w/-]+)\.png
\L\1
...to process png's, etc.
([\w\/-]+)(\.jpe?g)
and replace with \L\1\2
its deleting your extension because you are never saving it in a matchgroup.
You could perhaps capture the extension too?
([\w/-]+)(\.jpe?g)
\L\1\2
And I think you should be able to use something like this for all the files:
([\w/-]+)(\.[^.]+$)
\L\1\2
Or if you specifically want to convert those jpegs, pngs and gifs:
([\w/-]+)(\.(?:jpe?g|gif|png))
\L\1\2
If it's okay for the extension to become lowercase as well, you could just do
^(.*)$
\L\1
As long as you're certain that all lines contain file names.
If you want to process only certain file formats, use
^(.*\.(jpe?g|png|gif))$
\L\1
I've got folder with about 1300 png icons. What I need is html file with all of them inside like:
<img src="path-to-image.png" alt="file name without .png" id="file-name-without-.png" class="icon"/>
Its easy as hell but with that number of files its pure waste of time to do it manually. Have you any ideas how to automate it?
If you need it just once, then do a "dir" or "ls" and redirect it to a file, then use an editor with macro-ability like notepad++ to record modifying a single line like you desire, then hit play macro for the remainder of the file. If it's dynamic, use PHP.
I would not use C++ to do this. I would use vi, honestly, because running regular expressions repeatedly is all that is needed for this.
But young an do this in C++. I would start with a plan text file with all the file names generated by Dir or ls on the command prompt.
Then write code that takes a line of input and turns it into a line formatted the way you want. Test this and get it working on a single line first.
The RE engine of C++ is probably overkill (and is not all that well supported in compilers), but substr and basic find and replace is all you need. Is there a string library you are familiar with? std::string would do.
To generate the file name without PNG, check the last four characters and see if they exist and are .PNG (if not report an error). Then strip them. To remove dashes, copy characters to a new string but if you are reading a dash write a space. Everything else is just string concatenation.
In a repository for a well known open source project, all files contain a version string with a timestamp as their first line:
<?php // $Id: index.php,v 1.201.2.10 2009-04-25 21:18:24 stronk7 Exp $
Even if I don't really understand why they do this - since the files are already under version control -, I have to live with this.
The main problem is that if I try to 'st' or 'diff' a release to get an idea of what was changed from the previous one, every single file contained in the repository is obviously marked as modified and the diffs become unreadable and unmanageable.
I'm wondering if there's a way to ignoring the first lines doing a diff/st when they match a regexp.
The project is under cvs - cvs, yes, you've read correctly - and included in a bigger mercurial repository.
I don't know about cvs, but with hg you can use any external diff tool with the bundled extdiff extension, and any modern tool should have the ability to let you ignore diffs that match certain patterns.
I swear by Beyond Compare, which allows arbitrary syntax definition.
kdiff3 has preprocessor commands that you can pipe the input through.
If you try
man diff
you'll find
--ignore-matching-lines=RE Ignore changes whose lines all match RE.
search "ignore matching lines" on the web gives examples :
diff --unified --recursive --new-file
--ignore-matching-lines='[$]Author.[$]'
--ignore-matching-lines='[$]Date.[$]' ...
(http://www.cygwin.com/ml/cygwin-apps/2005-01/msg00000.html)
Thus try :
diff --ignore-matching-lines='[<][?]php [/][/] [$]Id:'
