Syntax highlighting error in .sh file. #19053
Description
Steps to reproduce
vim 2:9.1.1882-1 running on debian testing with kernel 6.16.9+deb14-amd64
Using following file. Initially syntax highlighting works. Now uncomment line 7. Syntax highlighting below that line changes... Comment that line 7 out again, highlighting is back in working order.
PS. it does not help if I save the changes and reopen file with :e - syntax highlighting remains broken if line 7 is uncommented.
PPS. another variant of that same line, that does NOT break syntax highlighting:
FILENAME=$(sed -r -e "s,[:/]+,\.,g" -e "s,[^a-zA-Z0-9\._]*,,g" <<<${CLEANURL}) ;
PPPS. added line 12 to show what "fixes" broken syntax highlighting from that line forward.
#!/bin/bash
TMPDIR='/dev/shm' ;
WDIR='/mnt/tmp' ;
CLEANURL='http://localhost:8077/test' ;
#FILENAME=$(sed -r -e "s#[:/]+#\.#g" -e "s#[^a-zA-Z0-9\._]*##g" <<<${CLEANURL}) ; # syntax highlighting problem, when this row is uncommented
FILENAME=$(sed -r -e 's#[:/]+#\.#g' -e 's#[^a-zA-Z0-9\._]*##g' <<<${CLEANURL}) ;
HDRFILE="${FILENAME}.hdr" ;
FULLFILENAME="${WDIR}/${FILENAME}" ;
FULLHDRFILE="${WDIR}/${HDRFILE}" ;
# " # this line un-breaks broken syntax highlighting for following lines
TMPFILENAME="${TMPDIR}/${FILENAME}" ;
TMPHDRFILE="${TMPDIR}/${HDRFILE}" ;
Expected behaviour
I would expect this line not to break syntax highlighting. Line 8 is example of that same row, just using apostrophes in sed command - this line does not break syntax highlighting. Perhaps it helps tracking that bug down.
Pictures added from before and after uncommenting line 7.
