Implements a number of VSCode's language server functions for awk files: syntax checking, referencing and hovering.
Settings:
awk.maxNumberOfProblems: maximum number of problems listed in the editor.
awk.mode: can be "awk" or "gawk". Should be set according to the interpreter used.
awk.stylisticWarnings.missingSemicolon: true or false. When true, marks places
where a newline ends a statement. False by default, but true when in "awk" mode.
awk.stylisticWarnings.compatibility: when true, marks functions and global
variables only available in gawk.
awk.path: list of paths to include directories (only in gawk mode).
Peculiarities:
Comments with a double hash (##) before a function declaration are considered
doc-comments, and are shown in the hover text.
Using more than one space before a parameter in the function declaration makes it a local variable. Function call checking will follow
.
