" The following lines set Vim's errorformat variable, to allow the

" quickfix window to show Python tracebacks properly. It is much

" easier to use let than set, because set requires many more

" characters to be escaped. This is much easier to read and

" maintain. % escapes are still needed however before any regex meta

" characters. Hence \S (non-whitespace) becomes %\S etc. Note that

" * becomes %#, so .* (match any character) becomes %.%# Commas must

" also be escaped, with a backslash (\,). See the Vim help on

" quickfix for details.

"

" Python errors are multi-lined. They often start with 'Traceback', so

" we want to capture that (with +G) and show it in the quickfix window

" because it explains the order of error messages.

let s:efm = '%+GTraceback%.%#,'

" The error message itself starts with a line with 'File' in it. There

" are a couple of variations, and we need to process a line beginning

" with whitespace followed by File, the filename in "", a line number,

" and optional further text. %E here indicates the start of a multi-line

" error message. The %\C at the end means that a case-sensitive search is

" required.

let s:efm .= '%E File "%f"\, line %l\,%m%\C,'

let s:efm .= '%E File "%f"\, line %l%\C,'

" The possible continutation lines are idenitifed to Vim by %C. We deal

" with these in order of most to least specific to ensure a proper

" match. A pointer (^) identifies the column in which the error occurs

" (but will not be entirely accurate due to indention of Python code).

let s:efm .= '%C%p^,'

" Any text, indented by more than two spaces contain useful information.

" We want this to appear in the quickfix window, hence %+.

let s:efm .= '%+C %.%#,'

let s:efm .= '%+C %.%#,'

" The last line (%Z) does not begin with any whitespace. We use a zero

" width lookahead (\&) to check this. The line contains the error

" message itself (%m)

let s:efm .= '%Z%\S%\&%m,'

" We can ignore any other lines (%-G)

let s:efm .= '%-G%.%#'
