I've got the following directory structure:
Makefile.am
src/
mymod/
mod.cc
submod/
submod.cc
inc/
Makefile.am
mymod/
mod.hh
submod/
submod.hh
Using autotools, I'd like to distribute both a library made from src and the headers in inc. The top level Makefile.am looks something like
lib_LTLIBRARIES = mylib.la
mylib_la_SOURCES=./mymod/mod.cc\
./mymod/submod/submod.cc
SUBDIRS=inc
Then inc/Makefile.am has
mymod_includedir=$(includedir)
nobase_mymod_include_HEADERS=mymod/mod.hh\
mymod/submod/submod.hh
This works OK. I end up with whatever library stuff, and my headers get installed appropriately. However, I'd like to eliminate the recursion involved in the Makefile. The problem is that if I move the lines in inc/Makefile.am to the root directory, then I have to update the paths as follows:
mymod_includedir=$(includedir)
nobase_mymod_include_HEADERS=inc/mymod/mod.hh\
inc/mymod/submod/submod.hh
This results in my headers getting dumped as $PREFIX/include/inc/mymod/mod.hh and not $PREFIX/include/mymod/mod.hh like I want. I know I
could do something like
mymodincludedir=$(includedir)/mymod
mymod_HEADERS=inc/mymod/mod.hh
mysubmodincludedir=$(includedir)/mymod/submod
mysubmod_HEADERS=inc/mymod/submod/submod.hh
but that's pretty painful, because there's a lot of subdirectories, and more subdirectories within the subdirectories (we're distributing a 3rd party's code that our own headers need). What I'd like to be able to do is either tell automake to just copy the directories in /inc to $(includepath) along with every subdirectory it encounters within, or tell it to only strip part of the path from the header files I'm listing. Is this possible?
I think the closest you can find is Karel Zak's Makemodule.am approach for which nobase_ would work as you need.

In Julia, I can get the current directory from
#__DIR__
For example, when I run the above in the "Current" folder, it gives me
"/Users/jtheath/Dropbox/Research/Projects/Coding/Current"
However, I want it to return one folder above the present folder; i.e.,
"/Users/jtheath/Dropbox/Research/Projects/Coding"
Is there an easy way to do this in a Julia script?
First, please note that #__DIR__ generally expands to the directory of the current source file (it does however return the current working directory if there are no source files involved, e.g when run from the REPL). In order to reliably get the current working directory, you should rather use pwd().
Now to your real question: I think the easiest way to get the path to the parent directory would be to simply use dirname:
julia> dirname("/Users/jtheath/Dropbox/Research/Projects/Coding/Current")
"/Users/jtheath/Dropbox/Research/Projects/Coding"
Note that AFAIU this only uses string manipulations, and does not care whether the paths involved actually exist in the filesystem (which is why the example above works on my system although I do not have the same filesystem structure as you). dirname is also relatively sensitive to the presence/absence of a trailing slash (which shouldn't be a problem if you feed it something that comes directly from pwd() or #__DIR__).
I sometimes also use something like this, in the hope that it might be more robust when I want to work with paths that actually exist in the filesystem:
julia> curdir = pwd()
"/home/francois"
julia> abspath(joinpath(curdir, ".."))
"/home/"
I know about using :modules, but what about when systems get nested? Suppose I have the following structure, relative to some unknown user directory:
foo/
-foo.asd
-bar/
--bar.asd
This could arise, for example, when using Git submodules. How shall I configure the (defsystem) call in foo.asd to load bar as a dependency, without modifying a config file outside of foo/ or demanding particular placement for the foo/ tree itself? Feels like it should be simple.
3 Feb. 2020: From #Svante's answer, it sounds like my question is really 'How do I dynamically ensure that foo/ and bar/ both get into the *source-registry*?' The ASDF manual makes me think this should do the trick:
(asdf:initialize-source-registry
'(:source-registry
(:tree "«absolute-path-to-foo»/")
:inherit-configuration))
though I have not seen an example of that usage.
26 Mar. 2020: The technique above seems to work fine, so I'm closing this question. ASDF 3 is excellent.
ASDF doesn't care about relative locations of .asd files. ASDF systems and their dependencies are completely orthogonal to file/directory structure and oblivious to any source version control.
It just looks in several locations for .asd files. Each such file then may contain definitions for systems. It will generally recurse into the configured folders, so any .asd file in a git submodule would usually also be found.
The definitions, e. g. of components, inside of an .asd file then work relatively from the location of that file.
In your example, if you give a :depends-on ("bar") option to the "foo" system, it would just work, no matter where bar.asd resides (as long as it is somewhere where ASDF finds it).
A bit more awareness would be required if you have several versions of a library. This might happen if you work on "foo" and "bar" at the same time, while a stable version of "bar" is also available, e. g. in a quicklisp dist. Then the lookup order comes into play, but usually your “personal” directories have precedence over “system” directories, so again, it would just work. For more control, you might want to look into qlot.
I really would like to know how to change directory to the next file, using 2 dots (/..).
I can go back to previous directory but how to do something like that to go to the next directory WITHOUT THE NAME OF THE FILE PLEASE!
I know it is possbile with the name of the folder but my answer is different, please let me know.
What O.S are you using? In linux ubuntu/Debian distributions (and probably in windows, not sure), you can enter the first child directory by simply typingcd */, this will change your current directory to the first child directory available in alphabetical order, example:
-/home
-alan
-desktop
-music
-alex
-documents
-pictures
-lisa
Assuming your in /home, if you write cd */ in the terminal you will be in /home/alan, because -alan is the first folder/directory available.
This is really a newbie question - but basically, how do I enable a template for certain filetypes.
Basically, I just want the template to insert a header of sorts, that is with some functions that I find useful, and libraries loaded etc.
I interpret
:help template
the way that I should place this in my vimrc
au BufNewFile,BufRead ~/.vim/skeleton.R
Running a R script then shows that something could happen, but apparently does not:
--- Auto-Commands ---
This may be because a template consists of commands (and there are no such in skeleton.R) - and in this case I just want it to insert a text header (which skelton.R consist of).
Sorry if this question is mind boggeling stupid ;-/
The command that you've suggested is not going to work: what this will do is run no Vim command whenever you open ~/.vim/skeleton.R
A crude way of achieving what you want would be to use:
:au BufNewFile *.R r ~/.vim/skeleton.R
This will read (:r) your file whenever a new *.R file is created. You want to avoid having BufRead in the autocmd, or it will read the skeleton file into your working file every time you open the file!
There are many plugins that add a lot more control to this process. Being the author and therefore completely biased, I'd recommend this one, but there are plenty of others listed here.
Shameless plug:
They all work in a relatively similar way, but to explain my script:
You install the plugin as described on the linked page and then create some templates in ~/.vim/templates. These templates should have the same extension as the 'target' file, so if it's a template for .R files, call it something like skeleton.R. In your .vimrc, add something like this:
let g:file_template_default = {}
let g:file_template_default['R'] = 'skeleton'
Then create your new .R file (with a filename, so save it if it's new) and enter:
:LoadFileTemplate
You can also skip the .vimrc editing and just do:
:LoadFileTemplate skeleton
See the website for more details.
Assume that your skeletons are in your ~/.vim/templates/ directory, you can put this
snippet in your vimrc file.
augroup templates
au!
" read in templates files
autocmd BufNewFile *.* silent! execute '0r ~/.vim/templates/skeleton.'.expand("<afile>:e")
augroup END
Some explanation,
BufNewFile . = each time we edit a new file
silent! execute = execute silently, no error messages if failed
0r = read file and insert content at top (0) in the new file
expand(":e") = get extension of current filename
see also http://vim.wikia.com/wiki/Use_eval_to_create_dynamic_templates
*fixed missing dot in file path
Create a templates subdirectory in your ~/.vim folder
$ mkdir -p ~/.vim/templates
Create a new file in subdirectory called R.skeleton and put in the header and/or other stuff you want to automagically load upon creating a new ".R " file.
$ vim ~/.vim/templates/R.skeleton
Then, add the following to your ~/.vimrc file, which may have been suggested in a way by "guest"
autocmd BufNewFile * silent! 0r $HOME/.vim/templates/%:e.skeleton
Have a look at my github repository for some more details and other options.
It's just a trick I used to use .
It's cheap but If you ain't know nothing about vim and it's commands it's easy to handle.
make a directory like this :
~/.vim/templates/barney.cpp
and as you konw barney.cpp should be your template code .
then add a function like ForUncleBarney() to end of your .vimrc file located in ~/.vimrc
it should be like
function ForBarneyStinson()
:read ~/.vim/templates/barney.cpp
endfunction
then just use this command in vim
:call ForBarneyStinson()
then you see your template
as an example I already have two templates for .cpp files
:call ForBarney()
:call ACM()
sorry said too much,
Coding's awesome ! :)
Also take a look at https://github.com/aperezdc/vim-template.git.
I use it and have contributed some patches to it and would argue its relatively full featured.
What about using the snipmate plugin? See here
There exist many template-file expanders -- you'll also find there explanations on how to implement a rudimentary template-file expander.
For my part, I'm maintaining the fork of muTemplate. For a simple start, just drop a {ft}.template file into {rtp}/template/. If you want to use any (viml) variable or expression, just do. You can even put vim code (and now even functions) into the template-file if you wish. Several smart decisions are already implemented for C++ and vim files.
I'm busy porting my build process from msbuild to cmake, to better be able to deal with the gcc toolchain (which generates much faster code for some of the numeric stuff I'm doing).
Now, I'd like cmake to generate several versions of the output, stuff like one version with sse2, another with x64, and so on. However, cmake seems to work most naturally if you simply have a bunch of flags (say, "sse2_enable", and "platform") and then generate one output based on those platforms.
What's the best way to work with multiple output configurations like this? Intuitively, I'd like to iterate over a large number of flag combinations and rerun the same CMakeLists.txt files for each combination - but of course, you can't express that within the CMakeLists.txt files (AFAIK).
The recommended way to do this is to simply have multiple build directories. From each one you simply call cmake with the required settings.
For example you could do, starting in the base source directory (using Linux shell syntax but the idea is the same):
mkdir build-sse2 && cd build-sse2
cmake .. -DENABLE_SSE2 # or whatever to enable it in your CMakeLists.txt
make
cd ..
mkdir build-x64 && cd build-x64
cmake .. -DENABLE_X64 # or whatever again...
make
This way, each build directory is completely separated from each other.
This allows you to have one directory for Debug, another for Release and another for cross-compiling.
There hasn't been much activity here, so I've come up with a workable solution myself. It's probably not ideal, so if you have a better idea, please do add it!
Now, it's hard to iterate over build configs in cmake because cmake's crucial variables don't live in function scope - so, for instance, that means if you do include_directories(X) the X directory will remain in the include list even after the function exits.
Directories do have scope - and while normally each input directory corresponds to one output directory, you can have multiple output directories.
So, my solution looks like this:
project(FooAllConfigs)
set(FooVar 2)
set(FooAnotherVar b)
add_subdirectory("project_dir" "out-2b")
set(FooVar 5)
set(FooAnotherVar c)
add_subdirectory("project_dir" "out-5c")
set(FooVar 3)
set(FooAnotherVar b)
add_subdirectory("project_dir" "out-3b")
set(FooVar 3)
set(FooAnotherVar c)
add_subdirectory("project_dir" "out-3c")
The normal project dir then contains a CMakeLists.txt file with code to set up the appropriate includes and compiler options given the global variables set in the FooAllConfigs project, and it also determines a build suffix that's appended to all build outputs - any even indirectly included output (e.g. as generated by add_executable) must have a unique name.
This works fine for me.
