Is there any way to get current document encoding (that is in the bottom bar) in my extension code?
Something like vscode.window.activeTextEditor.encoding
This does not appear to be possible.
Since it's nearly impossible to prove a negative, the rest of this answer documents what I explored.
The string "encoding" does not appear (in this sense) anywhere in the API docs nor in the index.d.ts file it is derived from. (With VSCode 1.37.1, current as of writing.)
I dug into the vscode sources to see if there might be a clever solution, but came up empty. The code that executes when the encoding is changed by the user is in editorStatus.ts, class ChangeEncodingAction. This makes its way to textFileEditorModel.ts, function updatePreferredEncoding, which sets preferredEncoding. That field controls what happens when the file is saved, and is used to populate the status indicator, but doesn't go anywhere else I can find.
Reading the status indicator itself does not appear possible since the API allows extensions to create new indicators with window.createStatusBarItem but not enumerate existing ones. And directly accessing the DOM is not possible.
I also came up empty searching through VSCode issues related to encoding, both open and closed, but only skimmed the most recent ~100 closed issue titles.
Alternatives
My main suggestion at this point would be to file an enhancement request on the VSCode github.
It should also be possible to do something with reflection but of course it would be fragile.
Finally, the encoding controls how the document in memory (a sequence of characters) maps to a file on disk (a sequence of bytes). Depending on what you're trying to do, it might work to speculatively encode the document in several encodings and compare each to what is on disk (so long as the file is not dirty).

I want to build a simple script that may be useful for others as well, but I have only very basic programming knowledge and can't do it myself without learning how to write powershell scripts from scratch.
What this script is supposed to do is, open an INI file (really just a txt), look for a variable with an assigned value and replace that value from a txt hosted on GitHub, save and then run a program.
This is for the tracker list of qBittorrent, since that feature still hasn't been implemented and the only other script that I could find that does this is for linux and mac, there seem to be none for windows.
The basic idea is this:
get-content "c:\users\[user]\appdata\roaming\qbittorrent\qbittorrent.ini"
# This is where pseudo code starts
get file from "[github-link.txt]"
save file to cache # keeping it is useless as it gets updated daily
find variable "Session\AdditionalTrackers=" in qbittorrent.ini
replace value of variable with content of cached file # this is what I struggle with most when looking for example code. Everything I could find specified the exact string that needed replacing, which in this case is quite long and may change with every update of the file.
overwrite original file
launch program qbittorrent.exe
end script
Conveniently or most likely deliberately all (most) of the tracker lists on GitHub are already formatted in a way that they can be directly pasted into the file without having to worry about formatting. Example.
I can totally understand if nobody wants to do the work, but I would greatly appreciate it and possibly others that are looking for a stopgap for the lacking feature.
If this already exists, go ahead and call me an idiot and while you're at it drop a link ;)
I just found a little tool called Power Automate and it pretty much does what I was looking for. It's not quite as elegant as a single click script but it does the job. Sadly I can't share the "flow" I built because, well, there is no option for it - thanks Microsoft. So, I'll try my best to write it out.
Not quite a "solution" but pretty to close to it.
Here is the "flow":
get file from web // from github for example
read text from file // read downloaded .txt file
read text from file // read qBittorrent.ini
crop text // crop between flags in qBittorrent.ini use "Session\AdditionalTrackers=" as start and "Session\GlobalMaxRatio=" as end and save to cropVar2
crop text // crop before flag use "Session\AdditionalTrackers=" as flag and save to cropVar1
crop text // crop after flag use cropVar2 as flag and save to cropVar3
replace text // replace cropVar2 with content of downloaded file and save to cropVar2
write text to file // write cropVar1,cropVar2,cropVar3
end flow
Keep in mind that any changes to the qBittorrent.ini may change the order of the entries. Which means you have to check if it's still correct after every update and after every change you make in the options. This is a massive cludge after all...
You can input fail saves so that you won't break anything if the order changed.
I sometimes use VSCode for a Delphi 7 project because I like VSCode's git functionality and for a few other reasons (superior string search, diff, etc).
Delphi 7 is a pain, and to get it to consistently compile I need to convert the dfm files to their binary version (all 2300 of them). This of course makes them unviewable in the diff viewer, or to just open the file?
Is there a setting where if I open that file, it will first pass it through the convert.exe (that's its actual name) util so that it can be viewed as a text? I understand that this might be read-only, which would be sufficient to my needs (though if on save it could just pass it back through, that'd be great too).
I'm having trouble figuring out what exactly to to search for on Google (the keywords seem too generic), but I can imagine some generalized functionality that would work for other environments beyond just Delphi/pascal.
Here's the use case: I'm writing a novel in Emacs (in org-mode). One part of my writing/editing flow is to read over some large portion of what I've written, collecting notes/possible edits/etc as I go. The sort of thing you'd do, on paper, by printing it all out and then writing notes in the margin.
I want to prevent myself from, as I do this kind of review, actually doing any writing -- but that's surprisingly hard. Like, if the buffer is editable, I start to type a brief note about a fix, then find myself starting to restructure / fix a sentence, and next thing I know, I've spent five minute polishing
a single paragraph. This not only slows me down, it breaks my ability to imagine a reader's response.
I've tried just putting the buffer in view-mode, and that sort of works -- but then it's laborious to try to identify the places I want to go back and review/fix up.
My ideal would be, to have something in view-mode, which I genuinely can't edit, but which, as I move the cursor through it, I could hit some key combination, and it would allow me to enter a brief note in the minibuffer, which would then get inserted into the main buffer, at point, possibly inside brackets or a comment or some such.
Does anyone know of something like that? Or have any pointers to something similar which I could try to adapt?
You can easily set bookmarks at any locations. And bookmarks can contain annotations.
If you use library Bookmark+:
The annotations are in Org Mode by default, and they can even be separate files (by default they are part of the bookmarks themselves, so stored in your bookmarks file).
You can bookmark not just a position but also a region of text, whether a sentence, paragraph, page, or an arbitrary span of text.
You can automatically name bookmarks as you set them, if you don't care about the names.
Updated after OP's comment saying "I prefer to shove the comments/questions/notes directly into the text of the novel. Because I end up adding/deleting/moving text a ton, and I want the notes to move with the text":
Bookmarks move with the surrounding text. That is, they generally get relocated automatically, since the surrounding text is recorded as part of the bookmark, and when jumping to a bookmark that text is looked for.
Occasionally the context has changed so much that a bookmark can't be relocated automatically, and you are prompted to relocate it manually.
But yes, bookmarks are stored in a bookmark file, separately from the files they target. There are both advantages and disadvantages to this feature. Advantages include (1) removing clutter from the text (annotations, including notes about possible text changes are metadata), (2) immediate access to particular text locations from anywhere, (3) a separate, persistent record/history of work or thoughts on it, (4) you can have multiple, separate sets of bookmarks/annotations for the same target text.
One thing you might find handy, when using bookmarks especially for annotating a particular file: C-x p C-l switches to a bookmark file that has only bookmarks for the current file or buffer, creating such a file on the fly if none
exists. (This is available only with Bookmark+.)
I am trying to use PostgreSQL to implement a full-text search system.
I encounter this strange or may be intended feature with that.
While trying to index or search for a column which contains names of files with extension (e.g. myimage.jpg), the system treats it as a url and does not properly tokenize.
I referred to the documentation and see that via ts_debug that the file name is taken as a host of a url.
Could some one tell how to take all inputs as normal word in the FTS of PostgreSQL.
Also, on a second request, how can one do a contains, startswith, and endswith searches with it?
Update
I have now tried the statement create text search configuration..., copied from pg_catalog.english and removed host,url, and url_path and then specified the configuration for the ts_debug method. But still no go., myimage.jpg is still identified as host.
Version
I use version 9.4
tl;dr Look at pre-parsing your input and removing punctuation if you really only want words (and not emails, urls, hosts, etc).
So after trying to figure this out myself the issue is that you don't seem to be able to easily customise the parser. From my understanding the parser runs first, which generates tokens. Those tokens are then matched to dictionaries.
By removing host, url, url_path from the configuration all you are doing is making it so that these tokens don't get looked up in a dictionary, resulting in no lexeme from these tokens. Which essentially means that they don't exist in terms of search. Which is not want you want...
Ideally what you need to do is customise the parser to not generate those tokens in the first place, or to also generate overlapping tokens (similar to how hyphenated words generate a token for the entire word as well as individual components) . This doesn't seem to be possible at the moment without writing a custom parser.
The only solution to this would be to pre-parse the text to remove the full stop. Note that if you rely on other types of tokens like version (e.g. 8.3.0) or email (e.g. name#domain.com) this will break those. So you may need to be a bit clever on how you remove characters.
select ts_debug('english', replace('this-is-a-file.jpg', '.', ' '));
"(asciihword,"Hyphenated word, all ASCII",this-is-a-file,{english_stem},english_stem,{this-is-a-fil})"
"(hword_asciipart,"Hyphenated word part, all ASCII",this,{english_stem},english_stem,{})"
"(blank,"Space symbols",-,{},,)"
"(hword_asciipart,"Hyphenated word part, all ASCII",is,{english_stem},english_stem,{})"
"(blank,"Space symbols",-,{},,)"
"(hword_asciipart,"Hyphenated word part, all ASCII",a,{english_stem},english_stem,{})"
"(blank,"Space symbols",-,{},,)"
"(hword_asciipart,"Hyphenated word part, all ASCII",file,{english_stem},english_stem,{file})"
"(blank,"Space symbols"," ",{},,)"
"(asciiword,"Word, all ASCII",jpg,{english_stem},english_stem,{jpg})"
In terms of your second question. Are you talking about partial word matches? You get this a little bit with the stemming when using a config like english, so running becomes run which will match if you search for run or running. If you're talking about fuzzy matching it gets a little more complicated. I suggest reading this article http://rachbelaid.com/postgres-full-text-search-is-good-enough/
I was wondering if there's a way to allow a buffer to edit multiple files at once.
Recently, I got vim working with eclim. But now I was wondering if I could edit multiple files at once in one buffer. For example, say I have an interface and a class file where I need to update a method signature is there a way I can load both of them into the same buffer and edit them simultaneously. Narrow region for multiple file regions. It would also be awesome to remember my settings but that could be a future iteration.
I saw this solution but it seems inconvenient to create a separate file to handle this interaction.
You can open all files as split windows (so you see all of them together), and :windo, :bufdo, :argdo allow you to perform mass-operations (like a :substitute) on all of them at once. There's usually no need for such artificial concatenation schemes, and as the linked article shows, it has its downsides over keeping the files separate.
