I have an include in one of my asciidoc files
include::{sourcedir}/samples/test.java[]
sourcedir is set when calling the asciidoc converter and contains an absolute path (starting /Users/User1...). However, asciidoc always puts the whole current path in front of the file when evaluating the expression. This ends up in an error
SEVERE: test.adoc: line 5: include file not found: /Users/User1/git/repo/workDir/Users/User1...[]test.jav
How can I make sure that asciidoc evaluated that path as an absolute path?

So I'm making a game with Ruby/Gosu and the lines to load all the images look like this:
#image_name = Gosu::Image.new(self, 'C:\Users\Carlos\Desktop\gamefolder\assets\bg.jpg', false)
I want to refer to them based on their location relative to the referring file. The file which includes the above line is in C:\Users\Carlos\Desktop\gamefolder\, so I would think I could just change the above to '\assets\bg.jpg' or 'assets\bg.jpg', but this doesn't work.
The specific error is "Could not load image assets/bg.jpg using either GDI+ or FreeImage: Unknown Error (Runtime Error)."
If you want to get the current directory (of your execution context, not necessarily the file you're 'in'), just use Dir.pwd. Output this to console to check that your current directory is actually gamefolder.
To get the current directory of your actual ruby file (relative to Dir.pwd), use __FILE__, e.g.
File.dirname(__FILE__)
Pass that to File.expand_path to get a fully-qualified path. You can do a little sanity check by making sure File.exists?("#{File.expand_path File.dirname __FILE__}/assets/bg.jpg") returns true.
(Try File.expand_path('assets/bg.jpg')...that might be all you need here.)
I have an image with the filename media_httpfarm3static_mAyIi.jpg.
I would like to search the parent folder and all subfolders of that parent folder for a file that contains that name - it doesn't have to be the EXACT name, but must contain that string.
E.g. this file should be returned: 11605730-media_httpfarm3static_mAyIi.jpg
So this is a 2-part question:
How do I achieve the above?
Once I have the file, how do I return the path for that file?
Use Dir::[] and File::absolute_path:
partial_name = "media_httpfarm3static_mAyIi.jpg"
Dir["../**/*#{partial_name}"].each do |filename|
puts File.absolute_path(filename)
end
This uses the glob "../**/*media_httpfarm3static_mAyIi.jpg" (go up one directory, then search all sub directories (recursively), for any file ending in the partial string "media_httpfarm3static_mAyIi.jpg". The relative paths are then returned in an Array.
You can use Array#each, Array#map, etc. to convert this into what you need. To convert a relative path, into an absolute path, just pass it to File::absolute_path.
Once you have the absolute path, you can use it to open the file, read the file, etc.
On File Paths
The glob "../**/*media_httpfarm3static_mAyIi.jpg" is relative to the current working directory. Normally, this is the directory from which the program was run. Not the directory of the source file. This can change using various utilities to change it.
To always use a glob relative to the source code file, try:
Dir[File.expand_path('../**/*#{partial_name}', __FILE__)]
You can also use:
Dir[File.join(__dir__, "..", "**", "*#{partial_name}")]
Note: __dir__ was added in Ruby 2.0. For older versions of ruby use File.dirname(__FILE__)
In the first code sample File::absolute_path was used. In the last sample File::expand_path is used. In most situations these can be used interchangeably. There is a minor difference, per the documentations:
File::absolute_path
Converts a pathname to an absolute pathname. Relative paths are
referenced from the current working directory of the process unless
dir_string is given, in which case it will be used as the starting
point. If the given pathname starts with a “~” it is NOT expanded, it
is treated as a normal directory name.
File::expand_path
Converts a pathname to an absolute pathname. Relative paths are
referenced from the current working directory of the process unless
dir_string is given, in which case it will be used as the starting
point. The given pathname may start with a “~”, which expands to the
process owner’s home directory (the environment variable HOME must be
set correctly). “~user” expands to the named user’s home directory.
Ok so with siriproxy it my lib folder along with the rb file for the plugin I have created a myconfig.yml file so I can change certain settings by writing to that file.
I have been able to write to the file but only if I include the full path all the way from the home directory down.
But is there not a way to open the file from the same directory i am in? I have tried every path combination I can think of.
There has to be one i am missing
If you use the following in your ruby file, you should get the absolute path where it is
File.expand_path(__FILE__)
From doc __FILE__
The name of the file currently being executed, including path relative to the directory where the application was started up (or the current directory, if it has been changed)
From doc File.expand_path
Converts a pathname to an absolute pathname.
As you probably want the directory, you should use File.dirname(__FILE__), so the path of your file myconfig.yml should be obtained with
File.join(File.expand_path(File.dirname(__FILE__)), 'myconfig.yml')
In more recent Ruby (>=2.0.0), you can use __dir__ (from Archonic's comment):
Returns the canonicalized absolute path of the directory of the file from which this method is called. It means symlinks in the path is resolved. If FILE is nil, it returns nil. The return value equals to File.dirname(File.realpath(FILE)).
I am invoking VSDBCMD.EXE in my build process template, there is a custom setvar parameter that requires a reference to the current source directory, passing this path has become an unexpected challenge.
I've tried using relative paths and $(SourceDirectory) to no avail (it remains as the literal string "$(SourceDirectory)" when I see the debug output), the parameter needs an absolute path.
Is there any way to get the absolute path for the current source directory when the script runs?
In the DefaultTemplate build workflow there is a variable called SourcesDirectory that contains the absolute path.
If you pass it to an InvokeProcess you just type the variable name in the activity property, no $() around it.
It might be worth checking out this resource, where author makes use of ConvertWorkspaceItem within his build in order to pass in a string the disk location of a know target in source control
I'm more used to xml documents and tools, but I need to deal with sgml. I have an sgml document that I'm using nsgmls to parse, and I need to include a particular sgml declaration with it. It works fine if I specify the declaration file on the command line:
$ nsgmls mydoc.decl mydoc.sgml
But I'd like to include the reference to the declaration within the sgml file (and not the entire declaration). Including it like a xml doctype i.e., <!DOCTYPE MyDoc SYSTEM "mydoc.decl"> fails with
mydoc.decl:1:2:E: unknown declaration type "SGML"
and the declaration isn't parsed (leading to lots of other errors). Trying to do the same thing as a SGML declaration: <!SGML MyDoc SYSTEM "mydoc.decl"> isn't any better, that gives me a fatal error:
mydoc.decl:1:0:E: character "<" invalid: only minimum literal and parameter separators allowed
mydoc.decl:1:0:E: cannot continue because of previous errors
Is there any way to just reference the external file, or will I always need to specify it on the command line?
You can't reference the SGML declaration from the DOCTYPE declaration. The DOCTYPE declaration should only point to the DTD.
What you can do though create a file named catalog (no extension) with an SGMLDECL entry in it. If you put this file in the same location as your SGML document, nsgmls will use it.
You can also point to the catalog file using -c on the command line, but that would defeat the purpose for you since you're trying not to reference anything else from the command line.
Here's an example catalog file pointing to a different SGML declaration file:
SGMLDECL somedir/mydoc.decl
If you have that catalog file in the same directory as "mydoc.sgml", you can leave the sgml declaration out of the command line:
nsgmls mydoc.sgml
