  • Python: Pass parameter one time, but use more times

    - by Gabriel L. Oliveira
    I'm trying to do this: commands = { 'py': 'python %s', 'md': 'markdown "%s" "%s.html"; gnome-open "%s.html"', } commands['md'] % 'file.md' But like you see, the commmands['md'] uses the parameter 3 times, but the commands['py'] just use once. How can I repeat the parameter without changing the last line (so, just passing the parameter one time?)

  • Any program or editor in windows 7 to run ".md" files

    - by Anmol Saraf
    I understand that '.md' is an extension for markdown format. While installing 'Grunt' from GitHub I see a lot of .md extension files inside node_module/grunt/docs folder. As per my understanding these files are supported by GitHub for documentation kind of things if I am not wrong. My question here is - Are there any editors/tools or programs available for Windows 7 where I can see these .md files executing ? When I try to open any of these file inside my text editor it displays in raw format with all '#" etc. keywords. I want to see the formatted version of these files so that without an internet connection also I can navigate the documentation on my machine. Thanks for helping !!

  • Suggestions for a CMS markup language for PHP

    - by Yanick Rochon
    As a learning experience, and as project, I am attempting to write a CMS module for ZF2. One of the functionality I would like to have is the possibility of adding dynamic contents in the pages by calling PHP functions in the view scripts. However, I do not want to give the users freedom in writing PHP code directly inside the page content, but rather implement custom view helpers (or widgets) to handle logic. For example: calling partial, partialLoop, url, etc. specifying arguments and all. I liked the idea of extending Markdown but this would get complicated when trying to add custom CSS class to elements, etc. Then I had the idea of simply doing a preg_replace on some patterns. For example, the string : ### partialLoop:['partials/display.phtml',[{id:'p1',price:4.99},{id:'p2',price:12.34}]] ### would be replaced by <?php echo $this->partialLoop('partials/display.phtml', array(array('id'=>'p1','price'=>4.99),array('id'=>'p2','price'=>12.34))) ?> Obviously, there would be some caching done so the page content is not rendered everytime. Does this sound good? If not, what would be a good way of doing this? Or is there a project already being developed for doing this? (I'd like to avoid heavy third party libs and something fairly or fully compatible with ZF2 would be nice.) Thanks.

  • Ubuntu won't boot after initializing the Build Environment for Android

    - by EntryLevelDev
    My laptop worked perfectly util I initialized the build environment for Android. The GUI won't start. It looks like some kinds of graphics card problems. I tried to fix it but after trying a lot of solutions on the internet nothing worked. (I only know basic linux stuffs.) I've already reinstalled the OS. However, I still want to build the Android from source. Any idea what might cause the problem? any workaround? Here is the command that I used to initialize the build environment: $ sudo apt-get install git gnupg flex bison gperf build-essential \ zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev \ libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 \ libgl1-mesa-dev g++-multilib mingw32 tofrodos \ python-markdown libxml2-utils xsltproc zlib1g-dev:i386 $ sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so My laptop model is asus u36sd. (https://help.ubuntu.com/community/Asus_U36SD) Thanks Edit: Base on this, I guess libgl1-mesa-glx:i386 might cause the issue. sudo apt-get install libgl1-mesa-dri:i386 The following packages will be REMOVED: libgl1-mesa-dri-lts-quantal libxatracker1-lts-quantal ubuntu-desktop xorg xserver-xorg-lts-quantal xserver-xorg-video-all-lts-quantal xserver-xorg-video-vmware-lts-quantal The following NEW packages will be installed: libdrm-intel1:i386 libdrm-nouveau1a:i386 libdrm-radeon1:i386 libdrm2:i386 libexpat1:i386 libffi6:i386 libgl1-mesa-dri:i386 libllvm3.0:i386 libpciaccess0:i386 libstdc++6:i386

  • Ninject : ninject.web - How to apply on a regular ASP.Net Web (!MVC)

    - by No Body
    What I am looking is something similar to the below (http://github.com/ninject/ninject.web.mvc): README.markdown This extension allows integration between the Ninject core and ASP.NET MVC projects. To use it, just make your HttpApplication (typically in Global.asax.cs) extend NinjectHttpApplication: public class YourWebApplication : NinjectHttpApplication { public override void OnApplicationStarted() { // This is only needed in MVC1 RegisterAllControllersIn("Some.Assembly.Name"); } public override IKernel CreateKernel() { return new StandardKernel(new SomeModule(), new SomeOtherModule(), ...); // OR, to automatically load modules: var kernel = new StandardKernel(); kernel.AutoLoadModules("~/bin"); return kernel; } } Once you do this, your controllers will be activated via Ninject, meaning you can expose dependencies on their constructors (or properties, or methods) to request injections.

  • Skip sanitization for videos in html5lib

    - by pug
    I am using a wmd-editor in django, much like this one in which I am typing. I would like to allow the users to embed videos in it. For that I am using the Markdown video extension here. The problem is that I am also sanitizing user input using html5lib sanitization and it doesn't allow object tags which are required to embed the videos. One solution could be to check the input for urls of well-known video sites and skip the sanitization in those cases. Is there a better solution?

  • Markup filter wanted for a public website

    - by sibidiba
    Developing a community site where everyone can post text, I'm looking for a markup filter: What is not part of the markup must be escaped (htmlspecialchars()) as it is. Should turn URL-s automatically into links Should support some form of basic markups (bold, image, url, pre, list) Should have a simple parser, that turns user input text into HTML Content on the site is public to everyone, XSS must not allowed to happen. What do you suggest? What markup language in the first place? BBCode? Wiki? Markdown? Are there any complete API-s with good examples? PHP is available on the server side. If there is a WYSIWYG-like texarea in addition (like here on SO) that would be a fantastic bonus!

  • CodeIgniter's XSS Protection is removing <script> tags from user inputs... but I don't want it to!

    - by Jack W-H
    Hey folks, CodeIgniter is brilliant but I'm using it to develop a site where users need to be able to share their code for websites. Unfortunately, CodeIgniter has been doing the "right" thing by removing <script> tags from my user's inputs into the database, so when it's returned data looks like this: [removed] User's data [removed] However, I need my site to DISPLAY script tags but obviously not PARSE them. How can I get CodeIgniter or PHP to return <script> tags, but still sanitise them for the database and return them without them executing? Thanks! Jack EDIT: By the way, it's not an option to use stuff like Markdown, everything has to output to copy-pastable code that could work with no modification somewhere else

  • Right recursive grammar or left recursive?

    - by user2485710
    I have little to no knowledge of what I'm about to ask, so I would like a suggestion based on the level of skills required to implemented a parser for the given grammar ( since I'm a beginner in this kind of formal approach to parsers and languages ). Just by going back of a couple of years, this situation reminds me a little of Pascal grammar vs C/C++ grammar, this left vs right stuff. But I'm not going to do any of that, my purpose is to implement a simple parser for a markup language for documents like Markdown. So considering that I'm starting with a markup language in mind, I want to keep things simple, which is the easiest one to handle between this 2 options and why . Another kind of grammar could be an easier option for me ? If yes which one do you suggest ?

  • align WMD editor's preview HTML with server-side HTML validation (e.g. no embedded javascript)

    - by Justin Grant
    There are many SO questions (e.g. here and here) about how to do server-side scrubbing of Markdown produced by the WMD editor to ensure the HTML generated doesn't contain malicious script, like this: <img onload="alert('haha');" src="http://www.google.com/intl/en_ALL/images/srpr/logo1w.png" /> This doesn't affect the WMD client's preview box. I doubt this is a big deal since if you're scrubbing the HTML on the server, an attacker can't save the bad HTML so no one else will be able to see it later and have their cookies stolen or sessions hijacked by the bad script. But it's still kinda odd to allow an attacker to run any script in the context of your site, and it's probably a bad idea to allow the client preview window to allow different HTML than your server will allow. StackOverflow has clearly plugged this hole. How did they do it? [NOTE: I already figured this out but it required some tricky javascript debugging, so I'm answering my own question here to help others who may want to do ths same thing]

  • Literate Haskell (.lhs) and Haddock

    - by finnsson
    At the moment I'm only using Haddock but after seeing some really interesting examples (e.g. this gist ) of literate Haskell I'm interested in trying it out in a project. The questions I got are: What do you write as Haddock comments and what do you write in the literate part? How do you scale literate programming to multiple files? Can anyone point me to an example where literate programming is used in a package with multiple modules? What is your experience of using literate programming in larger packages? Which flavour (markdown, latex, ...) of literate Haskell is preferred? Why are you programming in literate Haskell or plain vanilla Haskell? Are you programming in both styles and if so why? Do you prefer block-style (\begin{code}) or Bird-style (>)? Why?

  • Python 3-compatibe HTML to text converter preserving basic structure under permissive licence?

    - by hawk64
    I am looking for a relatively simple HTML to text converter which displays links and works on strings. So far I have tried lynx but performance is too bad, html2text which gives weird and verbose markdown output and is under GPLv3 which is too restrictive for my (BSD-licensed) project, http://effbot.org/librarybook/formatter-example-3.py using htmllib.HTMLParser with formatter.AbstractFormatter and a custom writer, however htmllib.HTMLParser is drpeceated and has been removed from Python 3. So is there any simple, performant, Python 3-compatible HTML to text converter under a permissive license such as MIT/BSD/Apache and the like? Edit: I dont just need something to strip HTML-Tags but also to preserve the basic structure of the HTML, that is output that somewhat resembles that of Lynx.

  • Ruby methods within Javascript within HAML

    - by Josh
    I have a jQuery script that adds a new field to a form, and this field contains dynamic information from an array. The problem is that I can't figure out how to add an array.each to populate the options of the select field within the javascript without breaking the HAML indentation and causing errors. Here is my best attempt that does not work: %script(type="text/javascript") $('#mylink').click(function() { $('#mylink').after('<select> - myarray.each do |options| <option value="#{options.id}">#{options.name}</option> </select>); )}; Also tried it with the :javascript filter with no luck. EDIT: For whatever reason, I can't get the 4-space indents ( for Markdown ) working here, but I do have it indented properly.

  • MySQL: Matching inexact values using "ON"

    - by Brad
    I'm way out of my league here... I have a mapping table (table1) to assign particular values (value) to a whole number (map_nu). My second table (table2), is a collection of averages (avg) (I couldn't figure out how to properly make a markdown table, please feel free to edit!) table1: table2: (value)(Map_nu) (avg) ---- ----- 1 1 1.111 1.045 2 1.2 1.09 3 1.33333 1.135 4 1 1.18 5 1.389 1.225 6 1.42 1.27 7 1.07 1.315 8 1.36 9 1.405 10 I need to find a way to match the averages from table2 to the closest value in table1. It only need to match to the 2 digit past the decimal, so I've added the Truncated function SELECT map_nu FROM `table1` JOIN table2 ON TRUNCATE(table1.value,2)=TRUNCATE(table2.avg,2) I still miss the values that don't match the averages exactly. Is there a way to pick the nearest truncated value? Thanks!

  • How far is too far?

    - by David Dorf
    Previously I've talked about Safeway's personalized pricing as well as Target's use of analytics to learn about customers.  Then last week I read about Orbitz tailoring their hotel offers based on the browser used.  (Orbitz claims that Mac users are 40% more likely than PC users to book four- or five-star hotels.)  So just how far is too far when tailoring the retail experience? When most consumers read about these types of tactics, they tend to feel violated, as if someone was reading their personal diary.  Nobody wants to be tricked into buying things.  Walking into a grocery store and seeing crates of apples stacked high looks enticing, but the crates are just for display and the apples may be over a year old.  Even though its much cheaper to print markdown tags, many retailers manually write the price tags because consumers think they deal is better if the price is hand-written. The technology already exists to personalize prices and experiences for consumers.  People get upset thinking they paid more for something than a neighbor, but it already happens all the time with cars, flights, and the use of loyalty programs and coupons. There are many variables at play for any purchase.  They only difference is that the customer segments are getting smaller, sometimes reaching a size of one. There's two ways to look at this.  Retailers have always manipulated the environment to get consumers to buy more -- or -- Retailers are getting better at tuning the shopping experience for consumers.  I choose the latter, and so do most consumers by spending their money in the stores they like.  Consumers like to see fresh flowers at the entrance to the grocery store, and they like to see specials scrawled on chalkboards. The key is making sure that consumers benefit from the experience as well.  I'm willing to give up some personal information in exchange for discounts and more relevant marketing, and the next-generation of shoppers are even less concerned about privacy.  Retailers need to use all the tools available to differentiate their offers and connect with their customers. So if Orbitz wants to put three-star hotels at the top of the list for me because I'm using a PC, that's fine by me.

  • Should a server "be lenient" in what it accepts and "discard faulty input silently"?

    - by romkyns
    I was under the impression that by now everyone agrees this maxim was a mistake. But I recently saw this answer which has a "be lenient" comment upvoted 137 times (as of today). In my opinion, the leniency in what browsers accept was the direct cause of the utter mess that HTML and some other web standards were a few years ago, and have only recently begun to properly crystallize out of that mess. The way I see it, being lenient in what you accept will lead to this. The second part of the maxim is "discard faulty input silently, without returning an error message unless this is required by the specification", and this feels borderline offensive. Any programmer who has banged their head on the wall when something fails silently will know what I mean. So, am I completely wrong about this? Should my program be lenient in what it accepts and swallow errors silently? Or am I mis-interpreting what this is supposed to mean? The original question said "program", and I take everyone's point about that. It can make sense for programs to be lenient. What I really meant, however, is APIs: interfaces exposed to other programs, rather than people. HTTP is an example. The protocol is an interface that only other programs use. People never directly provide the dates that go into headers like "If-Modified-Since". So, the question is: should the server implementing a standard be lenient and allow dates in several other formats, in addition to the one that's actually required by the standard? I believe the "be lenient" is supposed to apply to this situation, rather than human interfaces. If the server is lenient, it might seem like an overall improvement, but I think in practice it only leads to client implementations that end up relying on the leniency and thus failing to work with another server that's lenient in slightly different ways. So, should a server exposing some API be lenient or is that a very bad idea? Now onto lenient handling of user input. Consider YouTrack (a bug tracking software). It uses a language for text entry that is reminiscent of Markdown. Except that it's "lenient". For example, writing - foo - bar - baz is not a documented way of creating a bulleted list, and yet it worked. Consequently, it ended up being used a lot throughout our internal bugtracker. Next version comes out, and this lenient feature starts working slightly differently, breaking a bunch of lists that (mis)used this (non)feature. The documented way to create bulleted lists still works, of course. So, should my software be lenient in what user inputs it accepts?

  • Troubles installing/starting Redis via Resque

    - by Craig Flannagan
    Trying to complete instructions for Resque/Redis installation here: https://github.com/defunkt/resque/blob/master/README.markdown Am stuck at where I'm trying to start up Redis via Resque at the following command: Craig:/usr/local/src/resque$ rake redis:start (in /usr/local/src/resque) Detach with Ctrl+\ Re-attach with rake redis:attach ../../bin/dtach -A /tmp/redis.dtach ../../bin/redis-server ../../../etc/redis.conf rake aborted! Command failed with status (127): [../../bin/dtach -A /tmp/redis.dtach ../../...] (See full trace by running task with --trace) Rerunning with --trace (showing only part of trace): Craig:/usr/local/src/resque$ rake redis:start --trace (in /usr/local/src/resque) ** Invoke redis:start (first_time) ** Execute redis:start Detach with Ctrl+\ Re-attach with rake redis:attach ../../bin/dtach -A /tmp/redis.dtach ../../bin/redis-server ../../../etc/redis.conf rake aborted!

  • Evernote from vim

    - by juanpablo
    I search a way to edit evernote notes from vim I begin with this #!/bin/bash evernoteDir="$HOME/Library/Application*Support/Evernote/data" dataDir=$(ls -trlh $evernoteDir| tail -n 1| awk '{print $NF}') contentDir="$evernoteDir/$dataDir/content" file=$(ls -trlh $contentDir | tail -n 1| awk '{print $NF}') vim -c 's/div>/div>\r/g' $contentDir/$file/content.html https://gist.github.com/1256416 or maybe create a vim plugin for this ... you have any suggestion? EDIT: for a more simple edition of the evernote note in html format, I make this vim function " Markup function {{{ fun! MkdToHtml() "{{{ " markdown to html silent! execute '%s/ $/<br\/>/g' silent! execute '%s/\*\*\(.*\)\*\*/<b>\1<\/b>/g' silent! execute '%s/\t*###\(.*\)/<H3>\1<\/H3>/g' endf "}}} command! -complete=command MkdToHtml call MkdToHtml() nn <silent> <leader>mm :MkdToHtml<CR> " }}} and a vim function for open the last note edited fun! LastEvernote() "{{{ " a better solution is with evernote api let evernoteDir=expand("$HOME")."/Library/Application*Support/Evernote/data" let dataDir=system("ls -trlh ".evernoteDir."| tail -n 1| awk '{print $NF}'") let contentDir=evernoteDir."/".dataDir."/content" let contentDir=substitute(contentDir,"\n","",'g') let note=system("ls -trlh ".contentDir." | tail -n 1| awk '{print $NF}'") let note=substitute(note,"\n","",'g') sil! exec 'sp '.contentDir.'/'.note.'/content.html' sil! exec '1s/>/>\r/g' sil! exec '%s/<br.*\/>/<br\/>\r/g' sil! exec '%s/<\//\r<\//g' sil! exec 'g/^\s*$/d' normal gg sil! exec '1,4fo' sil! exec '$-1,$fo' endf https://gist.github.com/1289727

  • Does this exist: a standardized way of documenting a file-system structure

    - by eegg
    At work, I'm in charge of maintaining the organization of a whole lot of varied data on a standard file-system. Part of this is coming up with sensible classification (by similarity, need, read/write access, etc), but the bigger part is actually documenting it: what documents/files/media should go where, what should not be in this directory, "for something slightly different, see ../../other-dir", etc. At the moment, I've documented this using a plaintext file filing.txt in every directory I want to document. If someone is unsure what's meant to be in any directory, they read that file. This works alright, but it seems odd that I have this primitive custom solution to a problem that any maintainer of a non-trivial directory structure must experience. Every company I've known of, for example, has some kind of shared file-system where agreed terminology for categorization is important. In my experience, people just have to learn what's what by trial-and-error and experimentation. So allow me to propose a better solution, and hopefully you can tell me if it exists. Any directory on any filesystem can have a hidden plaintext file named .filing. Its contents are descriptive human language. It uses some markup like Markdown, with little more than bold, italic, and (relative) hyperlinks to other directories. Now a suitably-enabled file browser will check for a file named .filing whenever it displays a directory. If it exists, its contents are parsed and displayed in an unobtrusive pane near the directory-path widget. Any links therein can be clicked, and the user will be taken to the target directory of that link. I think that the effort of implementing such a standard would pay back many times over in usability gains. We would have, say, plugins for Nautilus, Konqueror, etc.. It could be used to display directory information in the standard file lists served by webservers. And so on. So, question: does such a thing exist? If not, why not? Do people think it's a worthwhile idea?

  • Git workflow for two tight-knit projects

    - by Pioul
    Two very similar projects I'm maintaining an online Markdown editor using Git as RCS (and accessorily made available on GitHub). From this web app, I've created a Chrome app: the code is the same, aside from some Chrome technicalities. I care about open sourcing these two projects. Still, the Chrome app's code being the same as the web app's except for some dull details, I've first chosen to (1) not publish the Chrome app on GitHub, and (2) not use Git to manage its code. Instead, I would manually review the web app's commits, then replicate the few changes in the Chrome app. … slightly drifting apart However, I've decided to add a feature to the Chrome app only. So, even though both codebases will remain broadly similar, they'll be diverging enough to make me reconsider the rationale behind my initial decision to not version control nor share the Chrome app's source code. Since I'm now willing to use Git to version control both apps, and that I want to share both of them on GitHub, how should I go about it? Should I use two different repositories, or one repo with two long-running branches? What would be the pros and cons of each approach in that context? What would be the easiest/fastest way to regularly "import" commits from the web app to the Chrome app, since the web app is going to remain the master branch? Is cherry-picking the only solution?
