• Numeric test when using the conditional operator

  - by lupuslupus

  In bash, why doesn't this work: $ echo $((1 -gt 2 ? 3 : 4)) bash: 1 -gt 2 ? 3 : 4: syntax error in expression (error token is "2 ? 3 : 4") Neither does this: $ echo $(((1 -gt 2) ? 3 : 4)) bash: (1 -gt 2) ? 3 : 4: missing `)' (error token is "2) ? 3 : 4")

• svn: default name for a tag when name is not important?

  - by Jason S

  I need to tag the current state of my source tree in svn. My problem is I don't care what the name is, I just need to mark the current revision in an immutable* manner. (*subject to malicious behavior) What's the best way to do this? branches/ tags/ ??? trunk/ should ??? be the date, an incrementing sequence, the repository rev # ...?

• How can I change the binding for template elements at runtime?

  - by Koynov

  I've found few solutions which assumes that I have 2 or 3 binding objects(or data templates) - that is not good solution for me. Is there an easy way to do this? I can think of cycling through the visual tree and set the binding that way but still this solution doesn't look very neat. Thank you in advance.

• indentationLevel property doesn't appear to do anything?

  - by JoBu1324

  I'm have a number rows I'm inserting into a table using -insertRowsAtIndexPaths:withRowAnimation, and I would like the rows to be indented from the left to distinguish them from the rest of the cells. The indentationLevel property of UITableViewCell looks like it's exactly what I need, but it doesn't seem to do anything. Here's the code I'm using to set the indentation level (dot syntax doesn't make a difference): [cell setIndentationWidth:10]; [cell setIndentationLevel:1]; Is indentationLevel what I want, or should I be looking elsewhere?

• $Id tag in comment headers

  - by Bernhard

  When I read source from open source projects I often find a comment line with "$Id" at the header of the file, f. ex.: // $Id: addappwindowa.c 30792 2009-03-07 22:40:04Z neil $ Is there an "offical" syntax for this lines? (What does "30792" means? ) Are there editors that auto-generate these "$Id"s? Are there any tools that use this information?

• how to reuse a CASE in the WHERE ?

  - by Thibault Witzig

  Hello I'm trying to do a request that looks like this SELECT field1, field2, field3 = CASE WHEN field2 = 'something' THEN 'something' WHEN field1 IS NOT NULL and field2 IS NULL THEN 'somethingElse' ELSE NULL END FROM SomeTable WHERE field3 IS NOT NULL This results in a syntax error. I have to rewrite the CASE in the WHERE instead of just refering to it. Is there a better way to achieve this ? And out of curiosity, why is "WHERE field3 IS NOT NULL" refused while for example "ORDER BY field3" would pass ?

• Jump to 'git add -i' patch command (5) directly

  - by felixge

  How can I get "git add -i" to start up in patch mode directly without having to type "5" + Enter? I know about "git add -p", but it's not the same as it doesn't show me a list of files to select from first. This is very annoying because I'd like to jump between "git add -i" and "git commit" very quickly to turn my dirty tree into some nice looking commits.

• quoting HTML attribute values

  - by Flavius

  Hi I know the spec allows both ' and " as delimiters for attribute values, and I also know it's a good practice to always quote. However I consider " being the cleaner way, maybe it's just me having grown up with C and C++' syntax. What is the cleanest way of quoting attribute values and why? Please no subjective answers.

• C: Convert A ? B : C into if (A) B else C

  - by tur1ng

  I was looking for a tool that can convert C code expressions for the form: a = (A) ? B : C; into the 'default' syntax with if/else statements: if (A) a = B else a = C Does someone know a tool that's capable to do such a transformation? I work with GCC 4.4.2 and create a preprocessed file with -E but do not want such structures in it.

• C++ Libraries similar to C#?

  - by cam

  I'm coming to C++ from a .Net background. Knowing how to use the Standard C++ Libraries, and all the syntax, I've never ventured further. Now I'm looking learning a bit more, such as what libraries are commonly used? I want to start getting into Threading but have no idea to start. Is there a library (similar to how .net has System.Threading) out there that will make it a bit easier? I'm specifically looking to do Linux based network programming.

• What is DEFAULT_CC in function declaration?

  - by humoeba

  I'm relatively new to C, and am curious what this syntax means in a function declaration: int DEFAULT_CC foo(void) where DEFAULT_CC is probably defined somewhere else as: #define DEFAULT_CC "cc" Is this a direction to use a certain compiler or something?

  Hi, i want to implement a small routing table for my learning? I know it is implemented using radix/patricia tree in routers? Can someone give me an idea on how to go about implementing the same? The major issue i feel is storing IP ADDRESS. For example : 10.1.1.0 network next hop 20.1.1.1 10.1.0.0 network next hop 40.1.1.1 Can someone give me a declaration of the struct from which i can have an idea?

• Getting a list of all children of a given commit

  - by intuited

  I'd like to run git filter-branch on all children of a given commit. This doesn't seem to be an easy task, since there doesn't appear to be a way to tell git rev-list to only return children of a particular commit. Using the .. syntax won't work because it will also include the parent commits of any merge within that range. Am I missing something here?

• How do I use multiple precisions in prinft()?

  Looking at the information under the heading "Precision can be omitted or be any of:". The example: printf("%.*s", 3, "abcdef"); works, outputting:abc (truncating the rest of the string.) Now, I would like to have a string with multiple parameters formatted (truncated): printf("%.*s", "%.*s", 3, 3, "abcdef", "xyz123"); but the program crashes. What is the correct syntax? Thank You.

• [boost::filesystem] performance: is it better to read all files once, or use b::fs functions over an

  - by rubenvb

  I'm conflicted between a "read once, use memory+pointers to files" and a "read when necessary" approach. The latter is of course much easier (no additional classes needed to store the whole dir structure), but IMO it is slower? A little clarification: I'm writing a simple build system, that read a project file, checks if all files are present, and runs some compile steps. The file tree is static, so the first option doesn't need to be very dynamic and only needs to be built once every time the program is run. Thanks

• How can I strip invalid XML characters from strings in Perl?

  - by AndrewR

  I'm looking for what the standard, approved, and robust way of stripping invalid characters from strings before writing them to an XML file. I'm talking here about blocks of text containing backspace (^H) and formfeed characters etc. There has to be a standard library/module function for doing this but I can't find it. I'm using XML::LibXML to build a DOM tree that I then serialize to disk.
