Regex alternate screen garbled

[eugenov]

Alternate screens shows garbage symbols for some expressions that use "+" or "*" symbols, i.e.

'(.|\r|\n)*?'|"(.|\r|\n)*?"|`(.|\r|\n)*?`

(everything in quotes) or

\$\b([_a-zA-Z0-9]+)\b

(every word starting with $) Is there any workaround for this? Example:

• print with "cat" (regex is working and coloring): [ "$VM" == "" ] || [ "$IP" == "" ] || [ "$NVIDIA" == "" ] && usage
• how it looks inside vim: [ "CCCOOONNN_SSSEEEQQQ____CCCOOONNN_SSSEEEQQQ$VMCCCOOONNN_SSSEEEQQQ____CCCOOONNN_SSSEEEQQQ" == "" ] || [ "CCCOOONNN_SSSEEEQQQ____CCCOOONNN_SSSEEEQQQ$IPCCCOOONNN_SSSEEEQQQ____CCCOOONNN_SSSEEEQQQ" == "" ] || [ "CCCOOONNN_SSSEEEQQQ____CCCOOONNN_SSSEEEQQQ$NVIDIACCCOOONNN_SSSEEEQQQ____CCCOOONNN_SSSEEEQQQ" == "" ] && usage

same with "less" seams OK

Just release 1.2.0, found no problem, maybe you can try it.

Confirmed, this single line does look good in vim. When in 100-line script - does not. Researching now. UPD2: full script with nano also seems better (but not perfect). UPD3: :syntax off makes file look good, but it garbles as cursor moves What realization of regex do you use?

I found there are some rare situation, the terminal will get mess by placeholder string, I made some fix in next release, maybe version 1.2.4 at tomorrow.

Tested 1.2.4 - perfect, garbage symbols CCCOOONNN_SSSEEEQQQ____CCCOOONNN_SSSEEEQQQ gone! Thank you for finding such quick solution! Still left some rare issues, but I believe it is because of faulty expression

If you want to elaborate - #.* (everything after #) replaced with [?12l[?25h with screen redraw when scrolling. I.e. When you open file with #!/bin/bash as header, you see #!/bin/bash, but if you scroll away and then return to this line - it will look like [?12l[?25hh Ah, will leave issue open, if you don't mind. Just to remember... UPD: this happens only when you scroll with mouse wheel. If you scroll with keyboard - everything is fine.

released 1.2.5,may fix this.

Yep, right now don't see any problems regarding this issue. Thank you!
