I have found the following filetypes.*.conf: ``` /usr/share/geany/filedefs/filetypes.Arduino.conf /usr/share/geany/filedefs/filetypes.CUDA.conf /usr/share/geany/filedefs/filetypes.Clojure.conf /usr/share/geany/filedefs/filetypes.Cython.conf /usr/share/geany/filedefs/filetypes.Genie.conf /usr/share/geany/filedefs/filetypes.Graphviz.conf /usr/share/geany/filedefs/filetypes.Groovy.conf /usr/share/geany/filedefs/filetypes.JSON.conf /usr/share/geany/filedefs/filetypes.Kotlin.conf /usr/share/geany/filedefs/filetypes.Nim.conf /usr/share/geany/filedefs/filetypes.Scala.conf /usr/share/geany/filedefs/filetypes.Swift.conf /usr/share/geany/filedefs/filetypes.TypeScript.conf /usr/share/geany/filedefs/filetypes.conf ``` * I thought (incorrectly, I hope) that `filetypes.conf` might be some generic skeleton starting point, but it states `# the lexer doesn't support keywords` which is a specific feature that I do want. * I have looked in `filetypes.perl` for some hint as to which lexer it uses, but it doesn't (well, not that I could see). There are arcane references in the manual to some Scintilla lexer but ... I don't see it in that list I just dumped. * Inside `filetypes.perl` there is a cryptic comment `# Edit these in the colorscheme .conf file instead` but, of course .... no indicatiion of which `.conf` file that s. So ... **Where can I found how to A) find out which lexer a builtin filetype uses (specifically `perl`)? B) which `.conf` I should perhaps start with?**
