Allow setting background colour of Fingerterm

Fingerterm is set to always have a black background, and it seems that changing the background colour can not be done without rebuilding the package from scratch (see: https://together.jolla.com/question/92925/how-to-change-fingerterm-background-color/)

Unfortunately many of the default terminal ANSI colours (for example dark blue, used by 'ls' for directories) get very hard to see on a black background, unless you increase the screen brightness to maximum - but doing so spends the battery much faster! I would like to have the colour settings for fingerterm accessible, preferably in the interface, but at least in an editable text-file (QML or otherwise).

@sa1l0 - I do believe you are no longer a Jolla user (last seen this time last year) but I tried to get transparency and it wasn't happening, so for now, changing to solid colours is what we have.

NOT a complete answer, yet......and no need to rebuild the entire package (which I could not get SDK to perform).

Slowly, slowly, inching further into the request and the code, which with 3 minutes of guess work and some f**king around with one particular line of code, I have the following;

File edited for effect;

/usr/share/fingerterm/Main.qml

Line: 90; (original code)

color: bellTimer.running ? "#ffffff" : bgcolor

Changed to (as example);

color: bellTimer.running ? "black" : "purple"

The 'black' is the flashing part of the visible bell warning and the purple is the main background color - so in this case when deleting something back to the start of the line, the colours black and purple will flash. Then, you can use setterm commands to set text colour, as explained by @lakutalo

And here's a really pointless but fun solution for those who don't know which colour to choose for the background;

Add this line to Line: 93; (this is a resource hog because it is animated, you have been warned!)

    SequentialAnimation on color {
        id: bgcolor
        loops: Animation.Infinite
        ColorAnimation { from: "#9400D3"; to: "#4B0082"; duration: 5000 }//Violet>Indigo
        ColorAnimation { from: "#4B0082"; to: "#0000FF"; duration: 5000 }//Indigo>Blue
        ColorAnimation { from: "#0000FF"; to: "#00FF00"; duration: 5000 }//Blue>Green
        ColorAnimation { from: "#00FF00"; to: "#FFFF00"; duration: 5000 }//Green>Yellow
        ColorAnimation { from: "#FFFF00"; to: "#FF7F00"; duration: 5000 }//Yellow>Orange
        ColorAnimation { from: "#FF7F00"; to: "#FF0000"; duration: 5000 }//Orange>Red
        ColorAnimation { from: "#FF0000"; to: "#9400D3"; duration: 5000 }//Red>Violet
    }

This is about as far as I can go with my limited knowledge, the rest is up to you guys, so, get editing! ;)

Regards,

I like your colours! You should put into a disclaimer the necessity of mental fitness for using your disco mode. ;)

Nice idea @lakutalo - Strobe mode (intense black and white flashing) for the 'light sensitive' among us ;)

You could also name it Epileptic Fit Countdown.

Nice hack!

It would really be appreciated if you fix this finally. Thank you.

Contact the original author of the application, as FingerTerm is not a Jolla/Sailfish app. The authors details are found on the About page in the application.

To set colours of input and output text, type e.g.
setterm --foreground black --background white

Allowed colours are: black | blue | green | cyan | red | magenta | yellow | white | default

It really works (as of 2.1.3.7), but yet I have not found a way to change the entire background. So this is merely one step into that direction.

foreground with an 'E', not forgound ;)

Spam Hunter ( 2017-11-20 18:29:54 +0300 )edit

You could knock me down with an F. But it wouldn't have worked without an E.

setterm sends terminal escape codes -- piping its output to od -a shows what is sent.

.

printf '\033[43m' outputs the same as setterm --background yellow when TERM=xterm

.

the escape codes to change window background are '\033' ']11;' '<color>' '\007' -- this is not supported buy fingerterm (at least colors did not change -- those codes may have been parsed though).

.

Look xterm control sequences for more information of those.

Still it only sets the background color of the text and not the entire terminal.

marsch ( 2017-11-21 02:39:32 +0300 )edit

the escape sequence ESC [ 4 3 m sets background color of the text to yellow (e.g. for highlighting purposes), not the background color of the whole terminal. the setterm --background may be considered confusing...
