What’s new in Calcpad, version 5.6.3?

Since version 5.6 was released, we made some little, but nice and useful improvements. They were driven mostly by our small and dedicated GitHub community. Some of the most important changes are listed below:

1. Autorun mode

When enabled, the results are refreshed automatically each time you edit the code and leave the current line. You can switch it on and off by the checkbox over the output window. When the “Autorun” is off, the program displays “Quick help” on the right as before. You can run calculations by pressing the respective button. However, new shortcuts were added to make that easier. Press F5 to run the calculations and F4 to compile to input form. Ctrl + Enter calculates the results and scrolls the output to match the current line.

2. Scroll enhancements

After recalculation, the scroll position of the output window is preserved and not moved to the beginning as before. However, if you get lost, you can double click on a line in the source code and the output will scroll to match. Alternatively, you can press Ctrl + Enter.

3. New symbols

The Symbol toolbar was extended with the full set of Greek letters. You can also change the case by pressing the button on the right.

There is also a shortcut to convert Latin to Greek letters. You can use it to insert Greek letters even faster. Just type the corresponding Latin letter and press Ctrl + G. The following conversion table is used:


Some special symbols were also added: ” ø “, “Ø”, ” ° “, “∡” and primes: ” ′ “, ” ″ “, ” ‴ “, ” ⁗ “. You can now use them in variable and function names. However, you cannot start a name with a number of prime symbol. Although primes look similar to quotes, they are different characters. So, there is no danger for the program to confuse them and start a comment.

4. Bugs and errors

There was a problem with recognition of inches (in) units in Complex mode that is now fixed. The “i” character was parsed as the imaginary symbol first and “n” dropped out as invalid unit.

Rewriting of non-metric (Imperial and USCS) units was also improved. For example, in the previous versions, lbf/in^2 was rewritten as kPa by default. Now, ksi is used instead. It is the same with other mechanical units.

Some rare bugs were luckily identified and fixed as well. For example, if you attempted plotting with identical limits, the program fell in infinite loop.

Debugging of Calcpad programs was made easier. Links to the respective lines in the source code were added to the error messages in the output. Also nice background highlighting was implemented.
