Render colored text to a ncurses window in python -


is possible to/how rendered pre-terminal-formatted colored text curses.window in python?

basically, i'm trying add simple curses-based ui stuff on top of existing console application renders colored log output, i'm trying redirect curses window.

however, seems curses somehow turns off various control codes control color.

here's minimal script, using colorama stand-in text-source:

import colorama import curses  def run_gui():     stdscr = curses.initscr()     curses.start_color()     curses.use_default_colors()      stdscr.insertln()     stdscr.insertln()     stdscr.insstr(colorama.fore.red+'wattt'+colorama.style.reset_all)     stdscr.insertln()     stdscr.insstr(colorama.fore.green+'wattt'+colorama.style.reset_all)     stdscr.insertln()     stdscr.insstr(colorama.fore.yellow+'wattt'+colorama.style.reset_all)     stdscr.insertln()     stdscr.refresh()  if __name__ == '__main__':      run_gui()

this renders:

^[[33mwattt^[[0m ^[[32mwattt^[[0m ^[[31mwattt^[[0m

is there way can tell curses allow normal control codes, or going have rework existing color functionality?

short: latter ("rework").

long:

the "normal control codes" happen device-dependent; curses provides device-independent interface terminals. quoting manual page:

the ncurses library routines give user terminal-independent method of updating character screens reasonable optimization.

actually curses implementations provide low-level interface via terminfo-based functions let special tweaks, but

  • python's binding doesn't include (it covers part of ncurses), and
  • for sort of thing suggested, not useful, since manipulating information curses designed know how manage more efficiently program do. preventing knowing what's on screen interfere curses does.

the python documentation mentions attributes, e.g., in window.insstr(str[, attr])

your example like

stdscr.insstr("wattt", color_pair(color_red))

what you're asking has been asked before. example:

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
