StaSH - is it possible to get color output from a script to the StaSH console?
-
Thanks ccc! I'll give that a look. I was using the terminal escape codes for a bash script, but they don't work in StaSh. A different way sounds fun!
Thanks again!

Thanks JonB! I certainly got those from the Pythonista docs. Was under the impression that was how StaSh was doing it. I didn't go down the code chain as far as I should have.
Thanks for the color references. That will work for now. I really didn't relish working through the couple hundred different color names I found on the web for CSS colors. You saved me some work! Thanks!
Good to know that there is another way to set text with a tuple. I might give that a look. With what you gave me though, probably won't need to do anything with that for awhile though!
Thanks again for the help!

Or you could just use base escape codes. That's what I use since they're cleaner and more dynamic:
class stashansi: fore_red = "\x9b31m" fore_blue = "\x9b34m" fore_end = "\x9b39m" back_red = "\x9b41m" back_blue = "\x9b44m" back_end = "\x9b49m" bold = "\x9b1m" underline = "\x9b4m" all_end = "\9x0m" print(stashansi.back_blue + stashansi.fore_red + "Hello world" + back_end + "This is just red with no blue background" + fore_end + "Now it's all just normal text...")
Be aware that whenever you print something with ANSI escape codes, you MUST use the ender escape codes to change the colors back to the original state, or else if your program ends, the colors will continue to be the same even outside of your program!

Thanks AtomBombed! That is very similar to what I was using with standard sh/bash escape codes.
I might update my code to use this, but it's working well right now, so ...
It's good to have the escape codes in one place though!
Thanks again!

I forgot and didn't mention -- I went the other way! I had this working on Mac terminal with colors and wanted it to work in StaSh. Now, it selects things dynamically and should work on either without any changes!
Thanks again!

Hi Mike,
You mentioned you went the other way - just wondering what this means, can you share an example that works interchangeably with StaSh and macOS terminal?
I am trying to accomplish a similar goal and any pointers would be greatly appreciated :-)
Thanks,

Hi Darren!
I made the classes (shown below) to handle the color. I had the TerminalColors class already written, so didn't want to change the interface to handle both cases, so I created the getTerminalColorClass() function to key off of the existence (or not) of the _stash variable that can give access to the text_xxx functions.
There is certainly some refactoring that could be done -- just haven't gotten to it yet. If I used the ANSI codes, as suggested, then it's likely all I would need to change are the actual definitions of the colors. I'd probably use some sort of enum that is defined differently like the getTerminalColorClass() function.
def getTerminalColorClass(): if _stash != None: return StashTerminalColors() return TerminalColors() class TerminalColors(object): """ here is a good url for the different colors and things: http://blog.taylormcgann.com/tag/prompt-color/ """ HEADER = '\033[95m' BLUE = '\033[94m' DARK_BLUE = '\033[34m' GREEN = '\033[92m' DARK_GREEN = '\033[32m' YELLOW = '\033[93m' DARK_YELLOW = '\033[33m' RED = '\033[91m' DARK_RED = '\033[31m' BOLD = '\033[1m' UNDERLINE = '\033[4m' CYAN = '\033[96m' DARK_CYAN = '\033[36m' WHITE = '\033[97m' PURPLE = '\033[95m' DARK_PURPLE = '\033[35m' END = '\033[0m' def __init__(self): pass def simple_print(self, color, str_msg): print( "%s%s" % (self.get_color_string(color, str_msg), self.END)) def complex_print(self, color, str_format, data): str_msg = str_format % data self.simple_print( color, str_msg ) def multi_color_print(self, color_str_tuple_list): str_msg = "" for clr, str in color_str_tuple_list: str_msg += self.get_color_string(clr, str) self.println(str_msg) def get_color_string(self, color, str_msg): return "%s%s" % (color, str_msg) def println(self, str_msg): print( "%s%s" % (str_msg, self.END) ) class StashTerminalColors (object): # from shcommon.py in stash code HEADER = 'UNDERLINE' BLACK = 'black' RED = 'red' GREEN = 'green' BROWN = 'brown' BLUE = 'blue' MAGENTA = 'magenta' PURPLE = 'magenta' CYAN = 'cyan' WHITE = 'white' GRAY = 'gray' YELLOW = 'yellow' SMOKE = 'smoke' DEFAULT = 'white' STRIKE = 'STRIKE' BOLD = 'BOLD' UNDERLINE = 'UNDERLINE' BOLD_ITALIC = 'BOLD_ITALIC' ITALIC = 'ITALIC' END = 'END' def __init__(self): self._stash = _stash def simple_print(self, color, str_msg): print("%s" % self.get_color_string(color, str_msg)) def get_color_string(self, color, str_msg): if color == self.BOLD: prn_str = _stash.text_bold(str_msg) elif color == self.UNDERLINE: prn_str = _stash.text_underline(str_msg) elif color == self.BOLD_ITALIC: prn_str = _stash.text_bold_italic(str_msg) elif color == self.ITALIC: prn_str = _stash.text_italic(str_msg) elif color == self.STRIKE: prn_str = _stash.text_strikethrough(str_msg) else: prn_str = _stash.text_color(str_msg, color) return prn_str def multi_color_print(self, color_str_tuple_list): str_msg = "" for clr, str in color_str_tuple_list: str_msg += self.get_color_string(clr, str) print(str_msg)
The class is pretty simple to use (written explicitly for my use case, so ... YMMV). I'll give examples of usage for both below.
Here are some examples of using simple_print():
tc = getTerminalColorClass() tc.simple_print(tc.BLUE, "this should be BLUE") print("hopefully, this is NOT blue") tc.simple_print(tc.DEFAULT, "this is the DEFAULT color (white)") tc.simple_print(tc.BROWN, "this is BROWN text") tc.simple_print(tc.BOLD, "this should be BOLD") tc.simple_print(tc.UNDERLINE, "this should be UNDERLINE") tc.simple_print(tc.STRIKE, "this should be STRIKETHROUGH") tc.simple_print(tc.ITALIC, "this should be ITALIC") tc.simple_print(tc.BOLD_ITALIC, "this should be BOLD ITALIC") # will combine multiple effects msg = '\n ID Status Date(-t) Owner(-u) Description (-d)\n' tc.simple_print(self.tc.BOLD + self.tc.UNDERLINE, msg)
Here is some example for multi_color_print():
def print_status_footer(): tc = getTerminalColorClass() # statusLine = "Status: [+]add [@]block [-]reject [*]accept [#]workon [.]finish" prn_list = [ (tc.WHITE, "Status: "), (get_color_for_status('+'), "[+]add "), (get_color_for_status('@'), "[@]block "), (get_color_for_status('-'), "[-]reject "), (get_color_for_status('*'), "[*]accept "), (get_color_for_status('#'), "[#]workon "), (get_color_for_status('.'), "[.]finish ") ] tc.multi_color_print(prn_list) tc.simple_print(tc.WHITE, " ST=status PR=priority")
The commented out line shows what it was before I added color to it. The get_color_for_status() just returns one of the colors defined in the terminal color class.
I hope that this helps!

Was finally able to test on my script on bash, so a small addition (actually just replace the getTerminalColorClass() function with the following:
def getTerminalColorClass(): if '_stash' in globals() or '_stash' in locals(): if _stash != None: return StashTerminalColors() return TerminalColors()
How I was checking before was never going to work! ;-)

Hi Mike,
I appreciate you taking the time to post your code, this is indeed very helpful.
Thanks!

You're welcome! Glad to help.
