    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 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:
        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):
        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)
        def get_color_string(self, color, str_msg):
            return "%s%s" % (color, str_msg)
        def println(self, str_msg):

        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)
                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)

    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.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!

    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!

    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!

    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!

    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!

    So, another question on this -- it seems that there is something not quite right.

    Looking at the documentation, it states:

    When setting this attribute, you can pass a string (CSS color name or hex, e.g. 'red' or '#ff0000'), a tuple (e.g. (1.0, 0.0, 0.0, 0.5) for half-transparent red), or a number (e.g. 0.5 for 50% gray).

    See the code below:

    print "text_color test"
        print _stash.text_color("red text - using color 'red'", 'red')
        print _stash.text_color("red text - using #ff0000", "#ff0000")
        print _stash.text_color("red text - using (1.0, 0.0, 0.0, 1.0)")
        print _stash.text_color("grey text - using 0.75")
        print "\n\n"
        ''' output is:
            text_color test
            red text - using color 'red' -- (this is actually red in output!)
            red text - using #ff0000
            red text - using (1.0, 0.0, 0.0, 1.0)
            grey text - using 0.75

    As noted with a comment, the only text that actually prints out red is when I'm using the 'red' color to text_color. Also, the last line (just a number -- 0.75) doesn't do anything except output standard white text.

    Is this expected? Should I be able to pass in the other ways to print red of a shade?

    Interestingly, the editor will correctly interpret the color values correctly by bringing up a 'popup' of the correct color. So, needless to say, I'm a little confused.

    As an aside, does anyone know what color values are actually valid?

    I have looked at the code, but haven't been able to find where the list of colors are (if there is such a thing). I've tried a bunch but only found these to actually give me colored output:

    • red
    • yellow
    • green
    • blue
    • black
    • grey
    • brown
    • cyan
    • magenta

    Thanks for any help or direction on this!

    That seems to work now. At least I can get the _stash variable and it's defined.

    Now, on to actually getting it to do what I'd like!

    Thanks for the help!

Internal error.
