I remember that there's a ".txt" file which allows to define link/compile-time arguments, but I've forgotten it's name.
I tried to google for answer.
The text file is called compile_flags.txt.
It's discussed at https://clangd.llvm.org/installation#compile_flagstxt.
Note that there are some shortcomings of compile_flags.txt compared to the more common way of configuring a project for use with clang-based tooling, compile_commands.json; most notably, clangd won't index your project with compile_flags.txt.

I wrote a plugin for babel that relies on the opts.filename and opts.filenameRelative properties. It seems to be working within babel-loader for the purposes of analyzing the adjacent files, but the filename itself seems to be modified.
I'm wondering if theres a way, using babel-loader, to get access to the full source file path to use for generating a legible id and hash.
babel-loader does indeed pass the filename into the transform function. In my particular case, I was preprocessing typescript files with awesome-typescript-loader, and that was messing with the file path.
.rkt is the conventional file extension for 'regular' Racket source code. In the documentation, I also see .rktl and .rkts being used. What are .rktl and .rkts used for, and are there any more Racket filename extensions I am not aware of?
The .rkt file extension is generally used for files that represent modules. These normally have a #lang .... line at the top, or sometimes (module ....). They can be imported as modules with require.
The .rktl and .rkts file extensions are used for files meant to be loaded at the top-level that aren't modules. They don't necessarily have a #lang .... line at the top, and must be loaded in some external environment with load instead of imported with require. These usually have a more "dynamic" feel to them, and they're used more often with scripts that use mutation of variables across multiple files. This is not the "encouraged" style in Racket.
The .rktd file extension is used for files that just have data encoded as s-expressions, not code. These files should not be required or loaded (they should not be executed as code). However, other programs use them to store data on the file system using write, and to read the data later using read. Its purpose is the same as a .sexp file or a .json file, just pure data.
For example, in my main.scm file I have (load "util.scm"). util.scm is a file in the same folder as main.scm. Both files are located in ~/documents/myproject/.
Now when I'm in this directory, and I run $ chez-scheme main.scm everything works fine. However, if I'm in my home directory and run $chez-scheme documents/myproject/main.scm it complains, not being able to find the file util.scm. I suppose this is the case because the current directory was my relevant home directory, and as such util.scm is indeed not there, it is actually in documents/myproject/. That being said, I'm used (in other languages) to the functionality of looking these paths up relative to the file containing the instruction to import, and I'd like to have that here as well. I've tried prefixing it by ./ or defining the file as a libary and doing (import (util)) but none of it works outside of documents/myproject/. Is there any way to get this to work as I intend it to?
I assume this is Chez-Scheme-specific. If not I'd prefer an answer that is implementation-neutral.
load is kind of awkward in R5RS since the report states that system interfaces are off topic in the report, but they include load which is a half hearted solution. The report does not say if the load is relative to the current directory or the file the load form originates from so in order to be portable I guess you are required to run your script from the current directory and have your loaded file relative to both.
Since Chez Scheme implements R6RS load is not really the right form to use. R6RS removed load in favor of libraries. You should make your file a library and consult how to install it. In some systems that is just placing the files in the right path, adding library location in configuration or running install script. How one uses the library is the same in all implementations, by using import.
According to Chez documentation you can pass --libdirs to it to give it one or more paths to consider for loading libraries. You can see the paths it scans by evaluating (library-directories)
There are several different ways to accomplish what (I think) you are trying to do, but eventually they all boil down to letting Chez know where to look for things. When given relative paths, include and load use the source-directories parameter to search for the requested file. Libraries have their path automatically prepended to source-directories while they are being loaded or compiled, so if your main.scm were a library definition then it would find util.scm as you expect.
However, it sounds like main.scm isn't a library, it's a top-level program. Unfortunately, Chez doesn't have a command line option to set the source-directories like it does for library directories. That leaves you with a bit less flexibility. Any of the following will work:
Make util.scm a library and invoke Chez with the --libdirs option to let it know where to look for libraries.
Set source-directories and load main.scm from inside the REPL rather than from the command line.
Write a wrapper shell script that does the above by echoing the commands into scheme so you don't have to type it yourself. (Only suitable if you don't also need to then type into the scheme session).
Write a wrapper shell script that cds into your project directory before running scheme (and presumably cds back to the original directory when it's done).
I m working on a Matlab project and I need UsbWebcams package for capture image from webcam. I can run .m file in matlab but when I compile project to create an exe file, My exe file return an error because usbWebcams package have some special .p files(Utility.p,webcamchannel.p etc) and I can not use these file for compiling.I searced on Internet and I didnt find any answer for this. How can I use .p files in my project. I think there should be a solution and I should find it. Thanks for helping to all.
Although MATLAB Compiler should be able to compile .p files, it's possible that the .p files you're trying to compile may have dependencies that you can't see because they're p-coded. For example, they might call an external library (this is quite possible if they are for interfacing with a webcam), or they might call another function using eval.
Whether they're .m files or .p files, if the files you're trying to compile have a dependency of this sort you need to include it explicitly for the Compiler, otherwise it won't know where to find it. But if the file is p-coded, it's tough to find out what the dependencies might be. You might need to ask MathWorks directly for support in compiling this functionality.
I'm trying to grok gettext.
Here's how I think it works -
First you use some sort of po editor and tell it to scan a directory for your application, create these ".po" files, the application makes a po file for each file scanned which contains a string in a programming language, then compile them to binary mo files, to which gettext parses, and you call a method using a high level API such as Zend_Translate and specify you want to use gettext, it can be setup to cache translations and it just returns those.
The part I'm really unclear about is how the editing of po files is done really, it's manual - right? Then when the compilation is done of course the application relies on the binary mo files.
And if someone could provide useful linux applications for editing .po files I'd be grateful.
The tutorial on NLS using GNU gettext should help you understand the process.
As for editing .po files, there's at least two applications (apart from vi :-): gtranslator and poedit.
