Broken output for approx results #46

Closed nick87720z closed 4 years ago

nick87720z commented 4 years ago

It seems, only first line from result output is printed. E.g., there is no problem with input like "4+5" or "(x-y)^2. But for "sqrt(3)" output is such:

  sqrt(3) = approx.

rofi-calc showes only first line: sqrt(3) = approx.

Would be better to show all lines before new prompt string.

Yet there is more complex output happens, e.g. with some recommendation (also I had cases in past when it told that unable to resolve something, but not it's hard to reproduce).

Example:

> integrate(sin(x) / cos(x), x, y, z)

  integrate(sin(x * radian) / cos(x * radian), x, y, z) = 0.5 * ln(cos(y)^2) - 0.5 * ln(cos(z)^2)

Could be great to have output/history in scrolled area. Though could be that it's rofi theming issue, where all widgets hierarchy is created along with styles.

Yet I think about way to preconfigure cli qalc for better output formatting. At least qalculate-gtk makes neat output.

Edit: using rofi-calc 1.6. It seems to be hard to reproduce.

nick87720z commented 4 years ago

Not sure, what was wrong. I tried in qalc cli - approximate/exact, as well as set precision 20 (was 512). Now it's as neat as in qalculate-gtk. However, rofi-calc output seems to be little affected, yet bug doesn't appear where it should be, showing full output for sqrt(3). Same for super-long output for integrate example above. I'm leaving it if anyone else can reproduce problem.

svenstaro commented 4 years ago

I'm afraid I can't reproduce this even with your given example. Maybe it's some config or your qalc version? I'm on qalc 3.9.0

svenstaro commented 4 years ago

I'll close this as I still can't reproduce. Maybe check your qalc config at ~/.config/qalculate/qalc.cfg if the problem persists. If you can show me how to reproduce this on a clean install, I'll try to fix it.
