Unnecessary restriction

[José M. Reigosa]

SnakeYAML 1.23.

When using DumperOptions IndicatorIndent and Indent and setting both values to the same one, a YAMLException (Indicator indent must be smaller then indent) is thrown. There is no reason for such a restriction. Please, remove it.

[Andrey Somov]

this is implemented to fix #358

We cannot fix it if you do not want to help.

@Andrey Somov I’ve my IntelliJ IDEA configured like this:

• indent = 2
• indent sequence value = true

Here’s the screenshot:

How can I configure snakeyaml not to reformat my yml files?

I tried to configure indent=2 and indicatorIndent=2, but the validation fails with message Indicator indent must be smaller then indent.

If I configure indent=6 and indicatorIndent=4 like it’s in https://bitbucket.org/asomov/snakeyaml/src/f437efd6719eaa93d616c7aca164a3d2d07f0031/src/test/java/org/yaml/snakeyaml/issues/issue358/UnexpectedIndentTest.java?at=default&fileviewer=file-view-default that will reformat simple maps

type: Example config
components:
  - name: First component
    description: Some short description of the first component

  - name: Second component
    description: Some short description of the second component

simpleMap:
  key1: value1
  key2: value2

Your picture above is identical to the file below. What is the problem ?

[Mikhail Kopylov]

Thanks for the quick reply.

The problem is I can’t make snakeyaml keep the IntelliJ IDEA format that is in screenshot (or code block, its' the same)

If I configure indent=4 and indicatorIndent=2 then the result look this way

type: Example config
components:
  - name: First component
    description: Some short description of the first component

  - name: Second component
    description: Some short description of the second component

simpleMap:
    key1: value1
    key2: value2  

But I want to have indent=2 for simpleMap

But I can’t have indicatorIndent greater or equal to indent

[Andrey Somov]

Since indicator is before the key, the indicatorIndent is always smaller than indent.

Unfortunately, it is very difficult to design the API in such a way that it fits all the use cases. The current settings do not allow it.

Feel free to make a proposal to improve the code !

[Mikhail Kopylov]

Ok, so could you please reopen this issue so that I can try to make a PR?

[Andrey Somov]

This issue is dead. Create another one with a proposal when you have it.

Or you can try to implement it in SnakeYAML Engine which is even better. You do not have backwards-compatibility problem.
