e.g. "-- brittany --indent=4"
respects the following comment forms as input:
source comment affected target
======================================================
"-- brittany CONFIG" whole module
"-- brittany-next-binding CONFIG" next binding
"-- brittany-disable-next-binding" next binding
"-- brittany @ myExampleFunc CONFIG" `myExampleFunc`
multiline-comments are supported too, although
the specification must still be a single line. E.g.
"{- brittany --columns 50 -}"
CONFIG is either:
1) one or more flags in the form of what brittany accepts
on the commandline, e.g. "-- columns 50", or
2) one or more specifications in the form of what brittany
accepts in its config files for the layouting config
(a one-line yaml document), e.g. "{ lconfig_cols: 50 }"
see #30
Arguments of two function applications will only be aligned
if the same function is called in both cases.
The column transform was altered slightly to fix#65
properly as well.
fixes#65, #128
This commit changes infix patterns to utilize `lrdrNameToTextAnn`. This
function allows the logic to avoid introspecting on the constructor
name.
Additionally this adds spaces to all infix operator pattern matches.
Previously infix symbols did not include spaces:
```
foo (x:xs) = _
```
Now they include a space
```
foo (x : xs) = _
```
Brittany was previously only support symbol based infix constructors. It
is common in some libraries (for example Esqueleto) to pattern match on
normal constructors as infix. Brittany was failing in this case by not
wrapping the constructor name in back ticks/spaces. Backticks and spaces
have been added in the case where the constructor contains any alpha
characters.
The following is wasteful of vertical space:
```
_ =
let
longIdentifierForShortValue = 1
in
longIdentifierForShortValue + longIdentifierForShortValue
```
We should format it on two lines if possible.
```
_ =
let longIdentifierForShortValue = 1
in longIdentifierForShortValue + longIdentifierForShortValue
```
This commit also allows for a mix of variations:
```
_ =
let
longIdentifierForShortValue = 1
in longIdentifierForShortValue + longIdentifierForShortValue
_ =
let longIdentifierForShortValue = 1
in
longIdentifierForShortValue + longIdentifierForShortValue
```
