I want the content to remain a text file, so code such as:
Approvals.Verify("some actual result as text");
Should continue to work. But I would like the approval tests to write to a ..approval.csv file or a ..approval.log file instead of ..approval.txt file.
I looked through the code and I think I may need to create a custom IApprovalWriter, but I also notice that the ExtensionWithDot property is read/write, so I'm wondering how this can be set.
Does anyone know how to do that?
ApprovalTests.Approvals.Verify(WriterFactory.CreateTextWriter(text, fileExtensionWithoutDot));
or for your example:
Approvals.Verify(WriterFactory.CreateTextWriter("some actual result as text", "log"));
Happy Testing!

I have a WebHelp content directory created using RoboHelp 9. From a web application, I'm trying to display a specific help page using their CSH JavaScript API:
RH_ShowHelp(0, "WebHelp/index.htm>MainWindow", HH_HELP_CONTEXT, <some map id>);
The problem is, the resultant popup always displays the first help topic, regardless of the map id I pass. Does the map file that was created for the RoboHelp project need to be included somewhere in the resultant WebHelp directory? I would think that RoboHelp would handle including whatever it needed in the generated content.
I think what's more likely is that I messed up somewhere in generating the map file/ids. To generate the map ids, I did the following:
Created a new map file
Double clicked it to open the map file window
Selected everything from the right list block (all the topics and help sections)
Clicked 'Auto Generate'
Are there further steps I need to follow before CSH will work?
Perhaps you forgot to include your mapfile in the generated output.
This is done in Web Help, under Content Categories.
Then, you can specify the topic number in the last argument to RH_ShowHelp.
Are you using the published output (not the generated output) in your content directory?
If that doesn't help, you can use simple links like this, which open the specified topic in help in the Help framework:
http://example.com/WebHelp/index.htm#someSubfolderThatIsAChildOfTheRootHelpFolder/theTopicYouWant.htm
We're creating an app that is going to generate some text files on *nix systems with hashed filenames to avoid too-long filenames.
However, it would be nice to tag the files with some metadata that gives a better clue as to what their content is.
Hence my question. Does anyone have any experience with creating files with custom metadata in Ruby?
I've done some searching and there seem to be some (very old) gems that read metadata:
https://github.com/kig/metadata
http://oai.rubyforge.org/
I also found: system file, read write o create custom metadata or attributes extended which seems to suggest that what I need may be at the system level, but dropping down there feels dirty and scary.
Anyone know of libraries that could achieve this? How would one create custom metadata for files generated by Ruby?
A very old but interesting question with no answers!
In order for a file to contain metadata, it has to have a format that has some way (implicitly or explicitly) to describe where and how the metadata is stored.
This can be done by the format, such as having a header that says where the "main" data is stored and where the "metadata" is stored, or perhaps implicitly, such as having a length to the "main" data, and storing metadata as anything beyond the "main" data.
This can also be done by the OS/filesystem by storing information along with the files, such as permission info, modtime, user, and more comprehensive file information like "icon" as you would find with iOS/Windows.
(Note that I am using "quotes" around "main" and "metadata" because the reality is that it's all data, and needs to be stored in some way that tools can retrieve it)
A true text file does not contain any headers or any such file format, and is essentially just a continuous block of characters (disregarding how the OS may store it). This also means that it can be generally opened by any text editor, which will merely read and display all the characters it finds.
So the answer in some sense is that you can't, at least not on a true text file that is truly portable to multiple OS.
A few thoughts on how to get around this:
Use binary at the end of the text file with hope/requirements that their text editor will ignore non-ascii.
Store it in the OS metadata for the file and make it OS specific (such as storing it in the "comments" section that an OS may have for a file.
Store it in a separate file that goes "along with" the file (i.e., file.txt and file.meta) and hope that they keep the files together.
Store it in a separate file and zip the text and the meta file together and have your tool be zip aware.
Come up with a new file format that is not just text but has a text section (though then it can no longer be edited with a text editor).
Store the metadata at the end of the text file in a text format with perhaps comments or some indicator to leave the metadata alone. This is similar to the technique that the vi/vim text editor uses to embed vim commands into a file, it just puts them as comments at the beginning or end of the file.
I'm not sure there are many other ways to accomplish what you want, but perhaps one of those will work.
So I'm running a test and it feeds its results out to a html or a xls file. This is great. However, when I go on the file, as expected the test that was run last is at the bottom. I want it at the top so that its easy to get too. is this possible?
I've tried using, r, r+, w, w+, a, and a+. They can delete whatever is already there but not write above it.
Is it possible to do something even harder and get it to print my results below a header, and above the previous results? Thanks.
This is not Ruby but OS specific. There is no operation to "write on top" of a file like append for writing stuff to the end.
You have to read in the file, edit the contents and write it back out. You can do this line-based, i.e. reading the first lines, writing them, write your extra content, write back the rest of the lines.
I have a simple FileCreator Ruby class that has 1 method create which creates a blank txt file on my desktop. Using RSpec, how would I test this create method to make sure
that the file was created, without having to create the file? Would I use RSpec::Mocks? Can someone please point me in the right directory? Thanks!
After calling file_creator.create(100) you could search the folder for all File*.txt files and make sure the count matches. (Make sure to have your spec remove the test files after completion).
Dir.glob(File.join(File.expand_path("~/Desktop"), "File*.txt")).length.should == 100
Using Mocks: You could do something like this to verify that the File.open method is actually being called (to test that the files actually get created, though, you may want to consider actually creating the files like the first half of my answer).
File.should_receive(:open).exactly(100).times
You could also try using something like FakeFS which mocks the actual file system.
The simplest way to do it is as below:
FileCreator.count.should eq 100
Good morning/evening
how can I write something in a file and then copy its content into the current file?
for example I consult file1.pro then I have rule write something in file2.pro , after this rule finish its job I want append the content of the file2.pro int file1.pro .
when I tried to append into file1.pro directly , the data appear like undefined symbols ,I don't know why
please hellp me
thank you.
Specifics of the solution might depend on the Prolog dialect. Here I am using SWI-Prolog. SWI-Prolog allows you to open a file with open(SrcDest, Mode, Stream), where SrcDest will be your file name, Mode is read/write/append/update, and Stream is the "file descriptor" the system will return. The manual clarifies difference between appending and updating as follows: "Mode append opens the file for writing, positioning the file-pointer at the end. Mode update opens the file for writing, positioning the file-pointer at the beginning of the file without truncating the file."
To copy from one stream to another you should use copy_stream_data(Stream1,Stream2).
Finally, you should close the streams, otherwise the output file will be empty.
Putting everything together gives
copy(File1,File2) :- open(File1,read,Stream1), open(File2,write,Stream2),copy_stream_data(File1,File2),close(File1),close(File2).
If you need to rewrite the second file, just use update/append mode.
