168 a range of consecutive warning numbers
169 <letter>
171 a predefined set
172 default setting is
174 "+a-4-7-9-27-29-30-32..42-44-45-48-50-60-66..70"
175 -warn-error <list>

188 Treat <file> as a file name (even if it starts with `-')
189 -color {auto|always|never}
191 Enable or disable colors in compiler messages
192 The following settings are supported:
194 auto use heuristics to enable colors only if supported

200 The default setting is 'auto', and the current heuristic checks
202 that the TERM environment variable exists and is not empty or
203 "dumb", and that isatty(stderr) holds.
204 If the option is not specified, these setting can alternatively
206 be set through the OCAML_COLOR environment variable. -er‐

208 warnings are printed
209 The following settings are supported:
211 short only print the error and its location
213 contextual
215 like "short", but also display the source code snippet corre‐
216 sponding to the location of the error
217 The default setting is 'contextual'.
219 If the option is not specified, these setting can alternatively
221 be set through the OCAML_ERROR_STYLE environment variable.
