restore some functions from SC

[jahblah]

It appears that a lot of SC functionality has been disabled or changed. Is there a list of things that no longer work with respect to SC files?

[andmarti1424]

hello. not really. have you check the doc? what commands you are having problems with?

[jahblah]

I've looked at the doc, but not thoroughly (forgive me). Mainly just to see how to do certain things. Example commands that don't seem to work any more are: "fkey", "tbl", "merge", and "write"; external function option renamed from "extfun" to "external_functions"; @ext() doesn't work as expected (see some of immae's posts); no -W commandline option; etc. Those are things I used extensively with SC when building external scripts, so not having them available any longer would require major changes to some sheets in order to have them work with SCIM.

[jahblah]

hit wrong button. oops.

[andmarti1424]

Yes, some commands were removed, some renamed. do you have this defined inside .sc files: "fkey", "tbl", "merge", "write" ???? regarding external functions, I will take a look at it since theres an open issue on this one.

take note that it was added lua scripting support. please take a look at the examples to see if they can help you..

"do you have this defined inside .sc files: "fkey", "tbl", "merge", "write" ????"

I use those commands in sc files, yes. It seems to be the only way to pass ranges to an external script. For example, the .sc file would have a line like:

fkey 3 = "merge \"|./foo.sh a0:c10 f0 /tmp/data\""

Then in foo.sh:

!/bin/bash

operation () { ret=$(whatever) # do something with the data echo ${ret} } range=${1} targetcell=${2} datafile="${3}" echo -n '' >${datafile} echo "write \"${datafile}\" ${range}" result=$(operation ${datafile}) echo "let ${targetcell} = ${ret}"

The downside is that you have to tap F3 to update the result when the data change, but I don't know of any other way to do it, since you can't pass ranges, or do back and forth communication, through @ext().

[jahblah]

fkey 3 = "merge \"|./foo.sh a0:c10 f0 /tmp/data\"" Escapes got lost when pasting above.

@andmarti1424 https://github.com/n-t-roff/sc has set mouse, and claims to be a fork of the latest sc, not sure if mouse was a later addition though.

[andmarti1424]

@reportaman I have included some mouse support lately. Did you check it out?

[poetaman]

@andmarti1424 Yes! It's not reliable though... I have a big display (27inch, 5k). There are 4 problems I see:

1. On some terminal emulators, clicking beyond a certain column visible on screen sends clicks to that column instead of the column user clicked on. For WezTerm its column J.
2. On some terminal emulators, clicking beyond a certain column does not do anything. For Alacritty & Kitty its column V.
3. On all terminal emulators, after scrolling a few pages to the right, and clicking on a cell actually sends click to some column on the left most page. Ex: Clicking on BQ8, selects a cell J8 & takes the view to J8.
4. On some terminal emulators like iTerm2 & Apple's default Terminal.app, pressing on the gutter to the right hangs sc-im, and its CPU usage remains at 100%. This happens when font size is relatively small (& column AD is visible in the opening view of sc-im), and does not happen for bigger font sizes (when column AD is not visible in opening view).

Sidenote: Vim does not have such problems (for same or even smaller font sizes), so I don't think its a terminal emulator implementation problem... (like some terms of past used to max out at 256 characters of width).

[andmarti1424]

Will check point 3. 1 and 2 acting differently depending on the terminal, could be more of an ncurses issue. 4.will try to test it reducing font size in my terminal. Don't have iterm to test.

[andmarti1424]

Confirmed. number 1 and 2 seems a bug in ncurses.. event.x gives wrong position! About number 3 you can update and test again. Idem about number 4. I dont have how to test it. Thanks!

[poetaman]

@andmarti1424 With your fix for 3, I confirm that both 3 & 4 too got fixed! So no worries if you don't have access to iTerm2.

With this fix there is no problem with Apple's Terminal & iTerm2, as 1 & 2 were not a problem with them to begin with. So Apple users can confidently use mouse with sc-im on Apple's Terminal & iTerm2. I tested by decreasing size to very small font size, and scrolling the screen to fill entire terminals with sc-im columns, and mouse works perfectly in these emulators.

It's weird that ncurses doesn't work well with other terminals. I have been gravitating towards WezTerm as it is the best of all IMO (at least nightly build with some recent fixes): it has inbuilt multiplexer that is not broken like Tmux, and is openGL based. I wonder if it is a bug with these terminals (WezTerm, Kitty, and Alacritty), and not ncurses?

[andmarti1424]

@reportaman check this out. https://stackoverflow.com/questions/50851532/mouse-support-with-ncurses-for-python-for-large-terminals this is what we see here. pass 222 columns it fails.

[andmarti1424]

but it fails sometimes. if i use alacritty + tmux it fails. if i use alacritty directly it doesnt. this is clearly a terminal thing.
