  • Emacs: adding 1 to every number made of 2 digits inside a marked region

    - by WizardOfOdds
    Imagine I've got the following in a text file opened under Emacs: some 34 word 30 another 38 thing 59 to 39 say 10 here 47 and I want to turn into this, adding 1 to every number made of 2 digits: some 35 word 31 another 39 thing 60 to 40 say 11 here 48 (this is a short example, my actual need is on a much bigger list, not my call) How can I do this from Emacs? I don't mind calling some external Perl/sed/whatever magic as long as the call is made directly from Emacs and operates only on the marked region I want. How would you automate this from Emacs? I think the answer I'm thinking of consist in calling shell-command-on-region and replace the region by the output... But I'm not sure as to how to concretely do this.

  • What is the closest thing MATLAB has to namespaces?

    - by rlbond
    We have a lot of MATLAB code in my lab. The problem is there's really no way to organize it. Since all the functions have to be in the same folder to be called (or you have to add a bunch of folders to MATLAB's path environment variable), it seems that we're doomed have loads of files in the same folder, all in the global namespace. Is there a better way to organize our files and functions? I really wish there were some sort of module system...

  • Accessing variable from ARGV

    - by snaken
    I'm writing a cPanel postwwwact script, if you're not familiar with the script its run after a new account is created. it relies on the user account variable being passed to the script which i then use for various things (creating databases etc). However, I can't seem to find the right way to access the variable i want. I'm not that good with shell scripts so i'd appreciate some advice. I had read somewhere that the value i wanted would be included in $ARGV{'user'} but this simply gives "root" as opposed to the value i need. I've tried looping through all the arguments (list of arguments here) like this: #!/bin/sh for var do touch /root/testvars/$var done and the value i want is in there, i'm just not sure how to accurately target it. There's info here on doing this with PHP or Perl but i have to do this as a shell script. EDIT Ideally i would like to be able to call the variable by something other than $1 or $2 etc as this would create issues if an argument is added or removed Any ideas?

  • Buy or build tool for Data Reporting ?

    - by Manoj
    We have been asked to provide a data reporting solution. The followng are the requirements: i. The client has a lot of data which is generated everyday as an outcome of the tests they run. These tests are run at several sites and they get automatically backed up into a central server. ii. They already have perl scripts which post process them and generates excel based reports. iii. They need a web based interface for comparing those reports and they need to mark and track issues which might be present in those data. I am confused if we should build our own tool for this or we should go for already exiting tool(any suggestions?). Can you please provide supportive arguments for the decision that you would suggest?

  • How to bind a double precision using psycopg2

    - by user337636
    I'm trying to bind a float to a postgresql double precision using psycopg2. ele = 1.0/3.0 dic = {'name': 'test', 'ele': ele} sql = '''insert into waypoints (name, elevation) values (%(name)s, %(ele)s)''' cur = db.cursor() cur.execute(sql, dic) db.commit() sql = """select elevation from waypoints where name = 'test'""" cur.execute(sql_out) ele_out = cur.fetchone()[0] ele_out 0.33333333333300003 ele 0.33333333333333331 Obviously I don't need the precision, but I would like to be able to simply compare the values. I could use the struct module and save it as a string, but thought there should be a better way. Thanks

  • Drupal ical for Authenticated users

    - by Linda
    I am using the calender module with it's iCal support for Drupal 6. I have made my event type which appear on the iCal feed. I however want to make the event content type private, so only authenticated users can read it. By doing this they will not show on the iCal feed. Is there any way that I could get the iCal feed to still show these events?

  • installing opencv for python issues

    - by vlad
    I'm running OS X Leopard. I followed this site to install it. Trying to run any demo script, I now get "No module named opencv.cv", which is obviously stopping me from doing any programming. I am running python 2.5.1 (yes, I know it's kind of old). Why would this be, and how can I solve it? Thanks

  • How to generate msdn documentation from javascript? preferably using sandcastle

    - by melaos
    hi is there a tool that i can use to generated msdn type documentation? i recently just started playing with sandcastle and i found that there used to a tool called scriptdoc but it has been absorbed into aptana and i don't really want to use aptana studio. what i could find so far is jsdoc which is a perl script which extracts comments from javascript files but i'm still looking for a better fit. from my initial testing it seems that the xml generated from jsdoc doesn't match completed with sandcastle or maybe i'm missing something there... any help?

  • How to remove EXIF data without recompressing the JPEG?

    - by Denilson Sá
    I want to remove the EXIF information (including thumbnail, metadata, camera info... everything!) from JPEG files, but I don't want to recompress it, as recompressing the JPEG will degrade the quality, as well as usually increasing the file size. I'm looking for a Unix/Linux solution, even better if using the command-line. If possible, using ImageMagick (convert tool). If that's not possible, a small Python, Perl, PHP (or other common language on Linux) script would be ok. There is a similar question, but related to .net.

  • Blit Queue Optimization Algorithm

    - by martona
    I'm looking to implement a module that manages a blit queue. There's a single surface, and portions of this surface (bounded by rectangles) are copied to elsewhere within the surface: add_blt(rect src, point dst); There can be any number of operations posted, in order, to the queue. Eventually the user of the queue will stop posting blits, and ask for an optimal set of operations to actually perform on the surface. The task of the module is to ensure that no pixel is copied unnecessarily. This gets tricky because of overlaps of course. A blit could re-blit a previously copied pixel. Ideally blit operations would be subdivided in the optimization phase in such a way that every block goes to its final place with a single operation. It's tricky but not impossible to put this together. I'm just trying to not reinvent the wheel. I looked around on the 'net, and the only thing I found was the SDL_BlitPool Library which assumes that the source surface differs from the destination. It also does a lot of grunt work, seemingly unnecessarily: regions and similar building blocks are a given. I'm looking for something higher-level. Of course, I'm not going to look a gift horse in the mouth, and I also don't mind doing actual work... If someone can come forward with a basic idea that makes this problem seem less complex than it does right now, that'd be awesome too. EDIT: Thinking about aaronasterling's answer... could this work? Implement customized region handler code that can maintain metadata for every rectangle it contains. When the region handler splits up a rectangle, it will automatically associate the metadata of this rectangle with the resulting sub-rectangles. When the optimization run starts, create an empty region handled by the above customized code, call this the master region Iterate through the blt queue, and for every entry: Let srcrect be the source rectangle for the blt beng examined Get the intersection of srcrect and master region into temp region Remove temp region from master region, so master region no longer covers temp region Promote srcrect to a region (srcrgn) and subtract temp region from it Offset temp region and srcrgn with the vector of the current blt: their union will cover the destination area of the current blt Add to master region all rects in temp region, retaining the original source metadata (step one of adding the current blt to the master region) Add to master region all rects in srcrgn, adding the source information for the current blt (step two of adding the current blt to the master region) Optimize master region by checking if adjacent sub-rectangles that are merge candidates have the same metadata. Two sub-rectangles are merge candidates if (r1.x1 == r2.x1 && r1.x2 == r2.x2) | (r1.y1 == r2.y1 && r1.y2 == r2.y2). If yes, combine them. Enumerate master region's sub-rectangles. Every rectangle returned is an optimized blt operation destination. The associated metadata is the blt operation`s source.

  • Injection of class with multiple constructors

  • Bipartite matching in Python

    - by vailen
    Does anybody know any module in Python that computes the best bipartite matching? I have tried the following two: munkres hungarian However, in my case, I have to deal with non-complete graph (i.e., there might not be an edge between two nodes), and therefore, there might not be a match if the node has no edge. The above two packages seem not to be able to deal with this. Any advice?
