Rultor fails to parse a valid yaml

[Glusk]

This is the .rultor.yml file I am using:

architect:
  - Glusk2
docker:
  image: "mingc/android-build-box:1.12.0"
release:
  script:
    - "chmod +x gradlew"
    # Increment versionCode
    - "perl -i.orig -pe '/versionCode/ && s/([0-9]+)/$1+1 . $2/e' android/build.gradle"
    # Strip tag of the "v" prefix
    - "version=${tag#'v'}"
    # Bump project version
    - "./gradlew release -Prelease.useAutomaticVersion=true -Prelease.releaseVersion=$version -Prelease.newVersion=$version-SNAPSHOT"

The online parser classifies it as a valid yml and parses it successfully. YAMLlint also confirms that it is in fact a valid .yml file!

However, invoking rultor like this:

@rultor release, tag=v0.9.0

failed with this error message (full log):

/home/r/script.sh: line 9: unexpected EOF while looking for matching `}'

@glusk2/z this project will fix the problem faster if you donate a few dollars to it; just click here and pay via Stripe, it's very fast, convenient and appreciated; thanks a lot!

@rultor config

@glusk2 This is how I understand the .rultor.yml file in the root directory of your base branch:

<?xml version="1.0" encoding="UTF-8"?>
<p>
   <entry key="architect">
      <item>Glusk2</item>
   </entry>
   <entry key="docker">
      <entry key="image">mingc/android-build-box:1.12.0</entry>
   </entry>
   <entry key="release">
      <entry key="script">
         <item>chmod +x gradlew</item>
         <item>perl -i.orig -pe '/versionCode/ &amp;&amp; s/([0-9]+)/$1+1 . $2/e' android/build.gradle</item>
         <item>version=${tag#'v'}</item>
         <item>./gradlew release -Prelease.useAutomaticVersion=true -Prelease.releaseVersion=$version -Prelease.newVersion=$version-SNAPSHOT</item>
      </entry>
   </entry>
</p>

This page explains how to configure it.

The following script line:

- "version=${tag#'v'}"

is successfully stored as an XML element in rultor store:

 <item>version=${tag#'v'}</item>

but on rultor execution it degenerates into:

version=${tag`#'\''\'\'''\''v'\''\'\'''\''}`

@Glusk2 the problem still exists?

@yegor256
I have since migrated the project to another automated release solution.

But the issue is still present in rultor.

Minimal reproducible example

.rultor.yml:

architect:
  - Glusk2
release:
  script:
    - "version=${tag#'v'}"

Such configuration would fail upon invoking rultor like this:

@rultor release, tag=v1.0.0

It does seem futile to undo all the effort that was put into dealing with the comment lines and make significant changes to how rultor starts its builds (as suggested here)

But as it stands, the following commands will not work in .rultor.yml:

• ${#parameter}
• ${parameter#word}
• ${parameter##word}

Unfortunately the information on the topic of this issue is scattered between several other issues.

Here is a list of my comments in related issues:

• my comment in #593 (exposes how that fix causes this issue + a possible path toward a more robust solution)
• my comment in #1193

This is a full list of related issues:

• comment in script breaks execution flow #593 (introduces handling of: # comments!)
• DockerRunTest.java:115-116: Add handling of hash inside... #625 (introduces handling of: echo "# comments!" and echo '# comments!')
• Rultor fails to create script.sh with particular character in script #1193 (I can only guess that Rultor fails to create script.sh with particular character in script #1193 is related to this issue because the original reporter has not provided the .rultor.yml configuration that was failing, although the error messages seem similar)
