I would like to obtain the LaTeX code associated with this theory. Previous answers only provide links to the documentation. Let me describe what I did.
I went to the directory of Hales.thy and executed isabelle mkroot, followed by isabelle build -D ., which generated a file named document and a *.pdf file which was suspiciously (nearly) empty. Modifications of this command by adding Hales.thy as a parameter didn't succeed.
I would appreciate if someone could describe briefly the commands needed.
As a precaution, copy the file Hales.thy into a new directory that does not contain any other files and run isabelle mkroot again.
If I understand correctly, your theory contains sorry. In this case, for the build to succeed you need to enable the quick_and_dirty mode. For this, before the first occurrence of sorry in your theory file, you need to insert declare [[quick_and_dirty=true]].
Your theory contains raw text that is not suitably formatted. Try replacing the relevant lines with the following: text‹The case \<^text>‹t^2 = 1› corresponds to a product of intersecting lines which cannot be a group› and text‹The case \<^text>‹t = 0› corresponds to a circle which has been treated before›.
Once this is done, you should be able to use the ROOT file in the appendix below. As you can see, I have specified the theory file explicitly and also added the relevant imported sessions.

I'm using SPSS 25 syntax to open and process a set of datafiles. I would like these syntax files to be as portable as possible. For that reason, I want the user to be able to select the file locations at runtime without having to recode the syntax itself.
I'm running Windows 10, although hopefully that doesn't matter. I do have the Python plugin for SPSS, although ideally this would be a base SPSS syntax solution.
In SPSS right now, I'm doing this:
GET
FILE='C:\Users\xkcd\studies\project\rawdata'+
'\reallyraw\veryraw.sav'
PASSWORD='CorrectHorseBatteryStaple'.
DATASET NAME Demo WINDOW=FRONT.
In R, I would do this:
message("Where is the veryraw.sav file?")
demo<-fread(file.choose())
Ideally, the user would, at runtime, select the individual files one at a time.
Less ideally, the user would select a folder in which all of the files, with known names.
I could use FILE HANDLE so that the user would only have to hardcode a few folder locations, but that's less than ideal - I really would rather that the user isn't editing the syntax at all.
Thanks in advance!
Following up on the idea of a fully automated process - the following code will work assuming there is a specific file name you need to run your code on, and only one copy exists in the folder you are searching. This is possible to run on drive C: directly, but will take much less time to run if you can narrow down the path:
* this will create a text file that has the path of the required file.
HOST COMMAND=['dir /s /b "C:\Users\somename\*required file name.sav" > C:\Users\somename\tempname.sps'].
* now to read the name and put in in a handle.
DATA LIST file = "C:\Users\somename\tempname.sps" fixed / pth 1-500 (a).
exe.
string cmd(a500).
compute cmd=concat("file handle myfile / name='", rtrim(pth), "'.").
write out="C:\Users\somename\tempname.sps" /cmd.
exe.
* inserting the new syntax will activate the handle.
insert file = "C:\Users\somename\tempname.sps".
Now you can use the handle myfile in the syntax, e.g:
get file=myfile.
I have a script which saves some files at a given location. It works fine but when I send this code to someone else, he has to change the paths in the code. It's not comfortable for someone who does not know what is in that code and for me to explain every time where and how the code should be changed.
I want to get this path in a variable which will be taken from the configuration file. So it will be easier for everyone to change just this config file and nothing in my code. But I have never done this before and could not find any information on how I can do this in the internet.
PS: I do not have any code and I ask about an ultimate solution but it is really difficult to find something good in the internet about dxl, especially since I'm new with that. Maybe someone of you already does that or has an idea how it could be done?
DXL has a perm to read the complete context of a file into a variable: string readFile (string) (or Buffer readFile (string))
you can split the output by \n and then use regular expressions to find all lines that match the pattern
^\s*([^;#].*)\s*=\s*(.*)\s*$
(i.e. key = value - where comment lines start with ; or #)
But in DOORS I prefer using DOORS modules as configuration modules. Object Heading can be the key, Object Text can be the value.
Hardcode the full name of the configuration module into your DXL file and the user can modify the behaviour of the application.
The advantage over a file is that you need not make assumptions on where the config file is to be stored on the file system.
It really depends on your situation. You are going to need to be a little more specific about what you mean by "they need to change the paths in the code". What are these paths to? Are they DOORS module paths, are they paths to local/network files, or are the something else entirely?
Like user3329561 said, you COULD use a DOORS module as a configuration file. I wouldn't recommend it though, simply because that is not what DOORS modules were designed for. DOORS is fully capable of reading system files in one line at a time as well as all at once, but I can't recommend that option either until I know what types of paths you want to load and why.
I suspect that there is a better solution for your problem that will present itself once more information is provided.
I had the same problem, I needed to specify the path of my configuration file used in my dxl script.
I solved this issue passing the directory path as a parameter to DOORS.exe as follow:
"...\DOORS\9.3\bin\doors.exe" -dxl "string myVar = \"Hello Word\"
then in my dxl script, the variable myVar is a global variable.
I'm planning to do a program with Lua that will first of all read specific files
and get information from those files. So my first question is whats the "my documents" path name? I have searched a lot of places, but I'm unable to find anything. My second question is how can I use the first four letters of a file name to see which one is the newest made?
Finding the files in "my documents" then find the newest created file and read it.
The reading part shouldn't be a problem, but navigating to "my documents" and finding the newest created file in a folder.
For your first question, depends how robust you want your script to be. You could use Lua's builtin os.getenv() to get a variety of environment vars related to user, such as USERNAME, USERPROFILE, HOMEDRIVE, HOMEPATH. Example:
username = os.getenv('USERNAME')
dir = 'C:\\users\\' .. username .. '\\Documents'
For the second question, there is no builtin mechanism in Windows to have the file creation or modification timestamp as part of the filename. You could read the creation or modification timestamp, via a C extension you create or using an existing Lua library like lfs. Or you could read the contents of a folder and parse the filenames if they were named according to the pattern you mention. Again there is nothing built into Lua to do this, you would either use os.execute() or lfs or, again, your own C extension module, or combinations of these.
I have a doubt about indicating a path in makefile and I'd like to have a clarification.
Suppose my structure is made this way:
/home/machinename/softwarefolder/mainfolder
--------------------------------------------> /subfolder1
--------------------------------------------> /subfolder2
This means that both subfolder1 and subfolder2 are at the same nesting level in /mainfolder.
Now I'm compiling something inside subfolder 2 (this means that I cd to that folder) that uses a configure file with a macro pointing to a path that, in my case, it's in subfolder1.
This configure file used by the program in subfolder2 to compile is generated automatically by the program itself after running ./configure
The automatically generated configure file has the macro defined this way
MACRO = ../subfolder1
Do the two dots (..) indicate, as in the cd command, "go back one step" (and, therefor, the configure file is pointing to the right folder)?
If the answer to the first question is "no", then why substituting the aforementioned macro with
MACRO = /home/machinename/softwarefolder/mainfolder/subfolder1
generates a "missing separator" error in compile-time?
Sorry for the probably trivial question and thanks for the help!
Make doesn't interpret the content of variables in any way, for the most part. The question of how the .. will be interpreted depends entirely on where the variable is used. If it's used in a place where a path like ../subfolder1 makes sense, then that's how it will be interpreted. If not, not.
Since you don't show how $(MACRO) is used, we can't help. But in general the answer to your question is "yes, it means go up to the parent directory".
As for your second question, there is no way I can envision that changing just that one line will result in a "missing separator" error. Maybe your editor "helpfully" made other changes to the file such as removing TABs and substituting spaces, or adding TABs? TAB characters are special in makefiles.
If you want help with the second question you must provide (a) the exact error you received (cut and paste is best), and (b) the exact text of the rule in the makefile at the line number specified in the error message.
I have a file that describes input data, which is split into several other files. In my descriptor file, I first give the path A that tells where all the other files are found.
The originator may set either a relative (to location of the descriptor file) or absolute path.
When my program is called, the user gives the name of the descriptor file. It may not be in the current working directory, so the filename B given may also contain directories.
For my program to always find the input files at the right places, I need to combine this information. If the path A given is absolute, I need to just that one. If it is relative, I need to concatenate it to the path B (i.e. directory portion of the filename).
I thought boost::filesystem::complete may do the job for me. Unfortunately, it seems it is not. I also did not understand how to test wether a path given is absolute or not.
Any ideas?
Actually I was quite misguided first but now found the solution myself. When "base" holds the path A, and filename holds B:
boost::filesystem::path basepath(base), filepath(filename);
if (!basepath.is_complete())
basepath = filepath.remove_leaf() /= basepath;
base = basepath.string();
It works with Linux at least (where it would be very easy to do without boost, but oh well..), still have to test with Windows.
