            Git hook for unstaged changes/file changes
            Asked 2021-May-31 at 10:08

            I'm looking to write a script that monitors all files/folders tracked by git to notify me if any of them have been changed. I'm looking for file changes and not necessarily staged changes.

            I've been combing through various SO questions and documentations, but I can't find any relevant examples for implementing a file system watcher based off of git that would be efficient, since I might want to implement this across a multitude of repositories and possibly hundreds of files all on one system without being extremely inefficient.

            Is git even the right solution for this? Would I be better off using fswatch even across many, many files?

            Many thanks

            Git itself doesn't watch the file system (*) and as such also doesn't provide any hooks when files change. It only inspects the file system whenever a git command is executed.

            Therefore there aren't (and can't be) any hooks that execute on file change. You'll need to find another way to watch the file system, if you need this.

            (*) Apparently there is a way to actually use file system monitoring in git, but that only seems to be used to speed up git status (and other operations) and still doesn't mean that git actively monitors changes. It just replaces "check each file for modification" with "check the list of changed files since the last time for modification".

            If you are dealing with Mongoose Documents, not with .lean() javascript objects, probably, you'll need to mark array field(s) as modified via markModified and only then use .save().

            Also, directModifiedPaths could help you to check, what fields has been modified in the document.

            I have noticed that your Alert_Activities, is actually an array of objects, so make sure that the result mongoose documents, which you are trying to .save() really satisfy all the validation rules.

            If changes on some fields do successfully saved but the others - don't, then if's definitely something wrong with field names, or validation. And the DB/mongoose doesn't trigger you an error, because the document has already been saved, even in particular.

            If you have output using both stdout and elasticsearch outputs but you do not see the logs in Kibana, you will need to create an index pattern in Kibana so it can show your data.

            After creating an index pattern for your data, in your case the index pattern could be something like logstash-* you will need to configure the Logs app inside Kibana to look for this index, per default the Logs app looks for filebeat-* index.

            Bash Script: Updating Top Half Of The Screen Separately Using Watch
            Asked 2020-Sep-09 at 21:50

            I'm working on a bash script that displays a random ANSI art banner on the top 16 lines of the screen, and then the project view of my todo.txt list in the remaining lines. This is intended to live in one pane of my tmux window, so that the right third of my screen (roughly 80x48 characters) is showing my todo list at all times.

            Right now I've got the banner randomizing on load, and then the todo list updates via fswatch whenever I add or remove something. I would also like to update the banner once every 15 minutes or so, so I'd like to use something like watch to run the command to cat a random ANSI banner on a 15 minute interval, but when using watch, the banner portion of the script just blanks out the entire screen. (the code below has a 10 second interval used for testing)

            Is there a better way to be doing this, or a way to get watch to start outputting the banners correctly?

            Here's the script:

            ANSWER

            Answered 2020-Sep-09 at 21:50

            It would appear that cat won't produce colored output in a format that watch will accept, as watching ls or some other colored output works fine, but nothing involving cat and colored output will do anything other than blank the screen.

            My answer involved ditching watch and just combining the scripts, running a bash loop in the background which updates the banner every 60 seconds. Unfortunately the writes to STDOUT are not atomic for either this loop or for the todo list, so I had to simply update variables containing the banner and the list, and update the entire screen every time the list file changes or it's 60 seconds and it's time for a new banner.

            This isn't ideal, because I'm redrawing a bunch of stuff that I don't have to redraw, but it's the only way to get around the fact that I can't find a way to make the writes to STDOUT atomic.

            When you are executing a program from your terminal, the first arguments will always be the name of your program, meaning sys.argv[0] will be the name of your script. What you want to use would probably be sys.argv[1], as everything after sys.argv[0] would be the actual parameters passed to the script.

            How to track order of newly created files in directory with fswatch
            Asked 2019-Jul-13 at 03:16

            I need to monitor a downloads directory, and keep track of the order in which files were written to the directory. The only way I know this is possible in macos is fswatch, but the documentation seems quite sparse compared to inotifywatch on linux.

            For example, if 001.jpg then 003.jpg then 002.jpg were downloaded to the directory (in that order), I would need a variable that looks like this: 001.jpg 003.jpg 002.jpg

            I only need to monitor new files in this case, not modified files. For example, if 001.jpg is modified, it should not be moved to the end of the list.

            How do you create a project directory tree view and tree store in GTK?
            Asked 2018-Sep-26 at 03:30

            I have been stuck on a problem recently with trying to create a project view in GTK. The issue is that my program constantly deletes and adds files to a project directory, but to account for these changes, the TreeStore of the project tree view needs to be cleared and repopulated. When the TreeStore is cleared and repopulated, the project TreeView collapses all of its headers. Take the following example:

            This is the project view before the program adds another folder named "SubProject2" under MainProject, clears the TreeModel, and repopulates it with the same directory.

            This is the project view after:

            Note that the folder "SubProject2" was added correctly under "MainProject", but the TreeView collapsed "MainProject".

            My current code for repopulating the TreeView is the following:

            Answered 2018-Sep-26 at 03:30

            The way I solved this problem was by storing expanded rows in a data structure before clearing the TreeView. I used a keyed data list to associate the name of the expanded row and its corresponding depth (row name is key and depth is value). I then clear the TreeView and repopulate it as usual. After, I traverse the TreeModel row by row. If the row name is a key in the keyed datalist and the row has the same depth as the depth value of the keyed datalist, I expand that row. Here is the code:

I tried adding | head -n $((`tput lines` - 1)) but the output is still overflowing because of line wrapping. I then tried using tput rmam in order to disable wrapping, but now I can't usually see where HEAD points to.

            Simply include fswatch.hpp and you're good to go. To start watching files, create an fswatch object and provide a variadic list of directories to watch. The constructor takes variadic arguments - Simply provide a list of directories to watch. This watcher will observe your home directory, /opt, /tmp and the current working directory.
