I love how GoLand can autocomplete the initialization of a struct with all fields and their zero values, however leaving said zero values in the struct initialization is not considered idiomatic and adds noise to the code. I'd like a code inspector to highlight these lines as a reminder to either set a different value, or remove them. I've read the very limited docs about writing custom code inspectors, but they really weren't helpful.

I tried having a TYPE_ENUM field but that requires typing some part of one entry (with the field performing autocompletion after that). I then thought about perhaps having a TYPE_ALNUM field that has each of the alternative values set in their respective buffers which I first set with set_field_buffer. But how do you switch between buffers then? Or maybe I should have overlapping fields and switch between them in the app? That seems nasty. Any help?
It seems like it's simply more straightforward to hard-code the text values. In an event that these values should be changed it seems like it would be more logical to search for the relevant UI element in each activity's xml layout file rather than look through the entire strings.xml. Of course if you have certain UI elements across multiple activities that all share the same text then this might be an exception (like a back button for instance), but generally there doesn't seem to be much advantage to storing these in the strings.xml. Am I missing something?
I will give you two reasons;
1 - Avoid duplication: all of your strings in one place. also, you can use string value many times. when you want to change it, there is one place to do the change. that makes it easier to maintain.
2 - Multi-language support: if you want to translate your strings to another language you must have all the strings in Strings.xml
let me know if you need more clarifications.
As a bit of context, I am considering making a plugin for vim that would inline specific debugging and/or profiling information on along the left margin (ideally left of the numbers column) which would need to be 4-5 characters wide. However, I cannot find any means to accomplish this. I've searched around, and the closest thing I can find is vimscript code for inserting signs in the sign column, but the sign column is fixed at 2 characters wide.
I've considered the possibility of making my own makeshift column (to the right of the numbers column, in the normally editable text area) and somehow marking it as readonly, but that doesn't seem possible either- from what I've read, the entire buffer must be readonly or not; you can't have just a portion as readonly.
For completeness here's an example. I would like to programmatically insert a 4-5 character column before some text (with numbers set)
1 Text buffer
2 with some
3 text
to make
My 1 Text buffer
own 2 with some
text 3 text
Is there any way to accomplish this task?
The built-in feature for this is the sign column, but yes it is limited to two characters.
Depending on your use cases, it might be okay to enhance the signs with a tooltip popup (:help balloon-eval explicitly mentions This feature allows a debugger, or other external tool, to display dynamic information based on where the mouse is pointing.), or maybe place the additional information in the quickfix or location list.
Modification of the actual buffer has many downsides (as it effectively prevents editing, and Vim's main purpose is just that). What some plugins do is showing a scratch (that is: unpersisted, unmodifiable) buffer in a vertical split, and setting the 'scrollbind' option so that its contents follow the original buffer. For an example, have a look at the VCSCommand plugin, which uses this for annotating a buffer with commit information.
NOTE: Although I give a lot of info on Inquirer, I'm pretty sure that most of it won't apply (just being safe). For my actual question about curses, its at the bottom.
I'm using the Inquirer module in Python 3 to allow the user to select a value from a list. I run this:
import inquirer
choice = inquirer.prompt([inquirer.List("size",message="Which size do you need?",choices=["Large", "Medium", "Small"])
And I'm given this:
[?] What size do you need?: Medium
Large
> Medium
Small
And using the up and down keys, I can change my selection, and hit enter to choose, after which the "choice" variable contains the value I selected. The issue is: Once the selection is done, the choices still show. I want to delete them when done. I'm currently using ANSI Escape Codes to delete the choices from onscreen when done, where x is the number of choices:
import sys
for i in range (x+1):
sys.stdout.write('\x1b[1A')
sys.stdout.write('\x1b[2K')
Which leaves the printed text as:
[?] What size do you need?: Medium
The issue is, ANSI escape codes aren't universal. I want to use a solution that works on all terminals, preferably curses, but curses isn't very friendly to new users, so I was wondering if anyone knew how to use curses to "delete x lines above current position". Thanks!
curses, as such, would erase the whole display (which is probably not what you want). A low-level terminfo/termcap approach might seem promising, but while ECMA-48 does define a sequence (ED, with parameter 1) which erases above the current position, there is no predefined terminfo/termcap capability which corresponds to this. All that you will find there is the capability for erasing to the end of the screen, or erasing the whole screen.
"ANSI sequences" is an obsolete term. Referring to ECMA-48, you could do
sys.stdout.write('\x1b[1J')
after moving the cursor to the last location you would like to erase.
Within my company we have an XML-based notation. Among other features, it is possible to define references from one XML document into another. I would like to enable autocompletion in Sublime so that whenever I am adding a reference, the possible files (i.e. XML files within the same project) and link points (i.e. symbols within that file) get offered as recommendations.
So far, I have found a lot of plugins that enable autocomplete for, say, HTML, PHP or LaTeX. However, I have the feeling the code base is too complex for a somewhat simple task. Is there, for instance, some vanilla function that generates completions based on an arbitrary array received as parameter? I would create the logic to determine what is a symbol and derive said array, but the whole process seems somewhat cumbersome to me.
(As a note: I can program in Python and have fiddled with other Sublime features, such as snippets, but these packages seem to be much more complex than it feels necessary.)
The base to create the completions entry is not to complicated. You now need to fill the array with the correct values (this could be done via a project setting or parsing other files).
import sublime
import sublime_plugin
# Your array, which contains the completions
arr = ["foo", "bar", "baz"]
class MyCompletionsListener(sublime_plugin.EventListener):
def on_query_completions(self, view, prefix, locations):
loc = locations[0]
# limit you completions scope
if not view.score_selector(loc, "text"):
return
completions = [(v + "\tYour Description", v) for v in arr]
return completions
OP's note: The answer works as advertised. However, the integration is so seamless that I thought for a while that something was missing. If the Python script above is on the right folder, all of the completions returned by the completions array will be suggested (depending on Sublime settings, it might be necessary to trigger the completions menu with Ctrl+Space). Also worth noting:
The completions may be None, in which case they just don't add any completion option, or an array of 2-tuples, where the first element is the description (which will be shown in the drop-down menu and trigger the completion) and the second is the value (i.e. the text that will be input if the completion is selected).
The score_selector method can be used to determine if the cursor position is within a given scope.
