%file will replace with full path to the file and not use stdio
%filepath will replace with full path to the file
%relativepath will replace with relative path of file
%dirname will replace with dirname of file
%tempfile will replace with the full path to a temporary file written with the contents
of the document and not use stdio; this file will automatically be deleted when the
command completes
t.sh:3:6: warning: Quote this to prevent word splitting. [SC2046]
t.sh:3:6: note: Useless echo? Instead of 'echo $(cmd)', just use 'cmd'. [SC2005]
t.sh:3:6: note: Use $(...) notation instead of legacy backticked `...`. [SC2006]
write pattern to match the line for linecolumnmessagesecurity:
const line = "t.sh:3:6: warning: Quote this to prevent word splitting. [SC2046]"
const formatPattern = "^[^:]+:(\\d+):(\\d+):\\s+([^:]+):\\s+(.*)quot;
const match = line.match(new RegExp(formatPattern))
console.log(match)
output:
{
0: "t.sh:3:6: warning: Quote this to prevent word splitting. [SC2046]"
1: "3"
2: "6"
3: "warning"
4: "Quote this to prevent word splitting. [SC2046]"
}
so you got:
line: match[1]
column: match[2]
message: match[4]
security: match[3]
and your formatPattern field will be:
"formatPattern": [
"^[^:]+:(\\d+):(\\d+):\\s+([^:]+):\\s+(.*)quot;, // line match pattern (javascript regex)
{
"line": 1, // diagnostic line use match group 1
"column": 2, // diagnostic column use match group 2
"message": [4], // message to display use match group 4
"security": 3 // security to use match group 3, ignore if linter do not support security
}
]
Notes
if the linter's message for per issue more then one line, you have to set the formatLines to fill your pattern,
and you can view the languagetool pattern for example which formatLines = 2
Each LSP client should support initializationOptions option,
all you need for diagnostic-languageserver is put the config in initializationOptions option.
