Please consider the following 2 example lines from an Apache config file:
Action xyzHandler /cgi-bin/xyzHandler
AddHandler xyzHandler .xyz
I understand that the effect of the above 2 lines is to "map" files that end with a .xyz extension to the executable /cgi-bin/xyzHandler. I would like to better understand what is meant meant by the term, "map". Does it mean that the contents of the file ending with a .xyz extension is applied to the standard input of /cgi-bin/xyzHandler? Does it mean that a path to the file ending in the .xyz extension is passed as an argument to /cgi-bin/xyzHandler? Does it mean something else? What exactly does it mean?
Thanks for any input.

In case anyone is interested, it turns out that this question is answered here: http://httpd.apache.org/docs/2.2/mod/mod_actions.html. In a nutshell, the answer is this: The /cgi-bin/xyzHandler script is simply executed. A path to the file ending with a .xyz extension that triggered the execution is made available via the standard CGI PATH_INFO and PATH_TRANSLATED environment variables. Thanks to all for your indulgence.

I thought for sure there would be an SO question on this, but I haven't been able to find one.
I have 2 SQL files, myFile1.sql and myFile2.sql. myFile1.sql calls myFile2.sql like so:
-- In myFile1.sql:
#scripts/myFile2
This works with no problem, but now I'd like to pass an argument to the file. I've tried doing the following, with no success (results in a File Not Found exception):
#scripts/myFile2 'ImAnArgument'
Does anyone know what the syntax would be to do this?
I'm guessing your problem is that scripts/myFile2.sql is a relative path from the script it is located in. If that is so, then it is following that path from the directory where SQL*Plus was started (the current working directory). If this is the problem, then it's not the parameter that is the issue, but rather that SQL*Plus can't find the file. In this case, you should use ##, which invokes the path relative to the file it's located in.
The parameter should work just as you proposed (documentation). Parameters provided when invoking a file are placed into substitution variables (rather than bind variables) and can be referenced by using an ampersand followed by the argument number. In your example, 'ImAnArgument' would be &1.
After many attempts, I wasn't able to pass a parameter in (and I still don't understand why not). But here is what I did to get the same affect:
-- In myFile1.sql:
DEFINE my_arg = 'ImAnArgument';
#scripts/myFile2
Then
-- In myFile2.sql
-- Do stuff using the variable my_arg, such as
SELECT my_arg FROM my_table;
I'm working on the documentation of a component using Doxygen and I want to include UMLdiagrams in between the text.
I know how to do most of it, as I simply need to copy the .tuml source into my .dox file and run doxygen. However, one of my diagrams is a class diagram that includes other .iuml files, like explained in the PlantUML site.
So, basically, I do:
#mainpage main_page MyDoxygen
\
...
\
#startuml
\
!include iuml_files/Class01.iuml
!include iuml_files/Class02.iuml
\
MainClass <|-- Class01
MainClass <|-- Class02
\
#enduml
Long story short, I don't know how to make Doxygen understand it must look for the .iuml files in the directory (relative path) I'm giving as argument to the include directive.
If I wasn't clear enough as to what I need, please let me know and I will try make it clearer.
Can I please get some help?
I had a similar problem (I own the Word Add-in for plantuml)
You can specify the java property "plantuml.include.path" in the command line :
java -Dplantuml.include.path="c:/mydir" -jar plantuml.jar atest1.txt
(see http://plantuml.sourceforge.net/preprocessing.html)
I expect it'll work when you modify the batch file for calling Plantuml
http://plantuml.sourceforge.net/doxygen.html
I had a similar request for my Word Addin for Plantuml and here it worked.
The Real Answer
Use the PLANTUML_INCLUDE_PATH = ./someRelativeDir configuration, visible in the Doxygen wizard's DOT panel.
The include path is relative to your Doxygen config, ie the starting directory from which the doxygen config is taken.
A Red Herring
I'm leaving the rest of this answer here in case anyone found it previously.
I wrongly reported a bug because I needed new reading glasses and didn't notice a stray character in my path.
This was resolved as not a Doxygen bug
For any interested parties, this is what I saw.
Running PlantUML on generated file /Users/andydent/dev/touchgramdesign/doxygeneratedTG4IM/html/inline_umlgraph_1.pu

This is using the configuration setting

Sharper eyes than mine (at the time) noticed the extra character in the path iuml t ToCopy
I am new to stackoverflow, but I got a lot of help until now, thanks to the community for that.
I'm trying to create a software showing me caller depandencys for legacycode.
I'parsing a directory with c code with pycparcer, and for each file i want to create a subgraph with pydot.
Two questions:
When parsing a c file, the parser references the #includes, an i get also functions in my AST, from the included files. How can i know, if the function is included, or originaly from this actual file/ or ignore the #includes??
For each file i want to create a subgraph, an then add all functions in this file to this subgraph. I don't know how many subgraphs i have to create...
I have a set of files, where each file is a frozenset with the functions of this file
somthing like this is pssible?
for files in SetOfFiles:
#how to create subgraph with name of files?
for function in files:
self.graph.add_node(pydot.Node(funktion)) #--> add node to subgraph "files"
I hope you got my challange... any ideas?
Thanks!
EDIT:
I solved the question about pydot, it was quiet easy... So I stay with my pycparser problem :(
for files in ListOfFuncs:
cluster_x = pydot.Cluster(files, label=files)
for functions in files:
cluster_x.add_node(pydot.Node(functions))
graph.add_subgraph(cluster_x)
I can address the pycparser part. The preprocessor leaves #line directives that specify which file & line code came for, and pycparser consumes those. You can get that information from the AST it creates (see tests for an example).
I am using OCLint static code analysis tool for objective-C and want to find out how to customize rules? The rules are represented by set of dylib files.
In lieu of passing configuration as arguments (see Jon Boydell's answer), you can also create a YML file named .oclint in the project directory.
Here's an example file that customizes a few things:
rules:
- LongLine
disable-rules:
rulePaths:
- /etc/rules
rule-configurations:
- key: LONG_LINE
value: 20
output: filename
report-type: xml
max-priority-1: 10
max-priority-2: 20
max-priority-3: 30
enable-clang-static-analyzer: false
The answer, as with so many things, is that it depends.
If you want to write your own custom rule then you'll need to get down and dirty into writing your own rule, in C++ on top of the existing source code. Check out the oclint-rules/rules directory, size/LongLineRule.cpp is a simple rule to get going with. You'll need to recompile, etc.
If you want to change the parameters of an existing rule you need to add the command line parameter -rc=<rulename>=<value> to the call to oclint. For example, if you want the long lines rule to only activate for lines longer than 150 chars you need to add -rc=LONG_LINE=150.
I don't have the patience to list out all the different parameters you can change. The list of rules is here http://docs.oclint.org/en/dev/rules/index.html and a list of threshold based rules here http://docs.oclint.org/en/dev/customizing/rules.html but there's no list of acceptable values and I don't know whether these two URLs cover all the rules or not. You might have to look into the source code for each rule to work out how it works.
If you're using Xcode script you should use oclint_args like this:
oclint-json-compilation-database oclint_args "-rc LONG_LINE=150" | sed
's/(..\m{1,2}:[0-9]:[0-9]*:)/\1 warning:/'
in that sample I'm changing the rule of LONG_LINE to 150 chars
I have a Matlab program that does something like this
cd media;
for i =1:files
d(i).r = %some matlab file read command
d(i).process();
end
cd ..;
When I change to my "media" directory I can still access member properties (such as 'r'), but Matlab can't seem to find functions like process(). How is this problem solved? Is there some kind of global function pointer I can call? My current solution is to do 2 loops, but this is somewhat deeply chagrining.
There are two solutions:
don't change directories - instead give the file path the your file read command, e.g.
d(i).r = load(['media' filesep 'yourfilename.mat']);
or
add the directory containing your process() to the MATLAB path:
addpath('C:\YourObjectsFolder');
As mentioned by tdc, you can use
addpath(genpath('C:\YourObjectsFolder'));
if you also want to add all subdirectories to your path.
Jonas already mentioned addpath, but I usually use it in combination with genpath:
addpath(genpath('path_to_folder'));
which also adds all of the subdirectories of 'path_to_folder' as well.
