Check the PHP blocks in feature files as the space-indented code they are - #362

Conversation
…espace A PHP block embedded in a feature file was handed to PHP_CodeSniffer as it stood, so the standard reindented it with tabs while the docstring around it stayed indented with spaces, and every fixed block came back mixing the two. The block is now converted on the way in and back on the way out: what is left of a line once the shared docstring indentation is off is indented with tabs for the check and the fixer, which is what the standard wants to see, and comes back indented with four spaces per level, which is what a feature file wants to hold. The two conversions are tab-stop expansions of each other, so a block that is already indented the way the standard asks for round-trips unchanged, and one that arrives with tabs -- from an earlier run of the fixer -- is normalized on the next one. The two runs of whitespace are converted apart rather than as one, as the tabs the fixer produced count from the start of the line as the fixer saw it, not from the start of the line in the feature file. Syncing a block back also trims trailing whitespace now. The fixer leaves some behind wherever it breaks a line, and the sniff that would clean that up cannot be part of the run, as it also wants the padding in front of the block gone -- `--exclude` takes sniff codes and not message codes, so the sniff has to go as a whole.

Pull request overview
This PR improves the extract-feature-php.php workflow so PHP snippets embedded in Behat .feature files (space-indented) are converted to tab-indented PHP during extraction for standards checking, then converted back to space indentation when syncing fixes back into feature files—while also trimming trailing whitespace and documenting the behavior.
Changes:
- Add tab-stop-aware indentation conversion helpers (
get_indent_width(),indent_with_tabs(),indent_with_spaces()) using a 4-columnTAB_WIDTH. - Update extraction/sync to convert indentation in the appropriate direction and trim trailing whitespace on sync-back.
- Extend PHPUnit coverage and update docs/shell tooling notes to reflect the new behavior.

utils/extract-feature-php.php:406
- In update_feature_php(), empty/whitespace-only lines are currently rewritten as a hard-coded "\n", which can convert CRLF feature files to LF for blank lines inside PHP blocks. Extract EOL before the empty-line check and reuse it for blank lines too.
foreach ( $code_lines as $line_content ) {
if ( '' === trim( $line_content ) ) {
$fixed_lines[] = "\n";

The previous commit had extraction rewrite a block's indentation to tabs and syncing rewrite it back to spaces, and had syncing trim the trailing whitespace the fixer leaves behind wherever it breaks a line. Both are things PHP_CodeSniffer can be told, so tell it instead. The sniffs that indent take a `tabIndent` property, and a ruleset can exclude a single message code where `--exclude` only takes whole sniffs. Neither can be said on the command line, so the run now uses a `WP_CLI_CS_Feature_Files` ruleset that turns `Generic.WhiteSpace.ScopeIndent` and `WordPress.Arrays.ArrayIndentation` around, swaps `Generic.WhiteSpace.DisallowSpaceIndent` for its opposite, and puts `Squiz.WhiteSpace.SuperfluousWhitespace` back to work with only the two message codes that would eat the padding in front of a block left out. A block is now checked and fixed as the space-indented code it is, so nothing has to be converted on the way in or out and `utils/extract-feature-php.php` is back to what it was. A tab or a run of trailing whitespace in a block is reported like any other violation rather than quietly rewritten, so `composer phpcs` says what `composer phpcbf` is about to do, and a block that already has tabs is brought back in line rather than left as it is. Fixing a heredoc is left to the sniffs as well, which know not to touch what is inside one.

…xclusion `Generic.PHP.CharacterBeforePHPOpenTag` is not a sniff. The sniff is called `Generic.PHP.CharacterBeforePHPOpeningTag`, so the exclusion has been doing nothing since it was added, and nothing went wrong because `--exclude` passes over a name it cannot resolve. That is the same leniency the list relies on to survive a standard that renames a sniff, and the reason the list cannot simply move into the ruleset: naming a sniff that does not resolve there aborts the whole run with exit code 3. Both files now say which half of the defaults they hold and why, so the split reads as a decision rather than as an accident. A package supplying a ruleset of its own replaces both halves, which the documentation now says as well.

changed the title
The exclusions were kept on the command line so that a name the installed PHP_CodeSniffer cannot resolve would be passed over rather than abort the run. That does not hold up. `WP_CLI_CS` already excludes five sniffs by name, so a standard that renames one takes `composer phpcs` down for every package before the blocks are ever reached, and the leniency bought nothing the main run does not already forgo. It is not even leniency worth having: an exclusion that stops resolving does not switch the sniff off, it switches the sniff back on, so the check starts reporting and the fixer starts rewriting feature files over something that was meant to be left alone. Aborting is the better failure. What the leniency did do was hide a dead entry for as long as it existed, which is an argument against it rather than for it. So the whole of the defaults now lives in `WP_CLI_CS_Feature_Files`: the exclusions, the warning severity, and the sniff configuration that could never have been anything but a ruleset. `phpcs/feature-files.sh` has nothing left to hold and is gone, and both scripts lose the sourcing along with the argument splitting it needed. `Generic.PHP.CharacterBeforePHPOpeningTag` is dropped rather than carried over. It is not part of `WP_CLI_CS`, so excluding it never did anything, and a ruleset resolves every name it is given. The blocks of `wp-cli/ability-command` come out of this byte for byte as they did before it.

Fixes two things noticed while running
composer phpcbfover the feature files in wp-cli/ability-command#13: a fixed block came back indented with tabs inside a docstring indented with spaces, and it came back with trailing whitespace after the closing parens the fixer had just broken onto their own lines.Both were the standard doing what it was configured to do, so this configures it differently rather than rewriting what it produces.
utils/extract-feature-php.phpis untouched.Why the blocks came back with tabs
Extraction hands a block to PHP_CodeSniffer with the shared docstring indentation taken off, and
WordPress-Coreindents with tabs. So the code inside the docstring was reindented with tabs while the six spaces in front of it stayed spaces:Three sniffs in the standard indent with tabs, and each can be told not to:
Generic.WhiteSpace.ScopeIndenttabIndentset tofalseWordPress.Arrays.ArrayIndentationtabIndentset tofalseGeneric.WhiteSpace.DisallowSpaceIndentGeneric.WhiteSpace.DisallowTabIndentput in its placeThose are the only three.
Universal.WhiteSpace.PrecisionAlignmentis already left out, andSquiz.Commenting.BlockCommentonly ever mirrors indentation that is already there.Why the blocks came back with trailing whitespace
PEAR.Functions.FunctionCallSignaturebreaks) );apart by putting a newline in front of the closing bracket, which leaves the space that was between the two brackets at the end of the line.Squiz.WhiteSpace.SuperfluousWhitespace.EndLinewould sweep that up on the next pass, but the whole sniff had to be left out because itsStartFilemessage also wants the padding in front of a block gone, and--excludeonly takes sniff codes:A ruleset can exclude a message code, so the sniff is back at work with only
StartFileandEndFileleft out.One place for the defaults
A sniff property and a message code exclusion are both things only a ruleset can express, so this adds a
WP_CLI_CS_Feature_Filesstandard next toWP_CLI_CS, and the rest of the defaults move into it: the exclusions, and the warning severity.phpcs/feature-files.shhas nothing left to hold and is deleted, and both scripts lose the sourcing and the argument splitting it needed.The exclusions were originally kept on the command line so that a name the installed PHP_CodeSniffer cannot resolve would be passed over rather than abort the run. That does not hold up:
WP_CLI_CSalready excludes five sniffs by name, so a standard that renames one takescomposer phpcsdown for every package before the blocks are ever reached.Generic.PHP.CharacterBeforePHPOpenTaghas been in that list since it was written and is not a sniff. It is dropped here rather than corrected, because the sniff it was reaching for,Generic.PHP.CharacterBeforePHPOpeningTag, is not part ofWP_CLI_CSeither, so excluding it never did anything.A ruleset resolves every name it is given, so an entry cannot rot that way again.
What changes for a package
A block is now checked and fixed as the space-indented code it is:
A tab or a run of trailing whitespace in a block is reported like any other violation rather than quietly rewritten, so
composer phpcssays whatcomposer phpcbfis about to do:A block that already has tabs, from a run of the fixer before this change, is brought back in line by the next one. What is inside a heredoc or a string is left alone, which the sniffs handle and a conversion in the extraction could not have.
A package that supplies its own
phpcs-feature-files.xmlshould start it fromWP_CLI_CS_Feature_Filesrather than fromWP_CLI_CSto keep the defaults, which the documentation now says.Testing
TestFeatureFilesRulesetruns the fixer over a block and checks what comes back: space indentation, array indentation, trailing whitespace removed, a block already indented with spaces left alone, and the padding in front of a block kept — the last being the one that would silently break every line number reported against a feature file.Checked by hand against the feature files of
wp-cli/ability-command, from before that PR and from the branch with the tabs already committed. Both end up byte for byte identical, with no tabs and no trailing whitespace,composer phpcsclean afterwards, and a secondcomposer phpcbfa no-op. Moving the exclusions into the ruleset leaves that output byte for byte unchanged.Summary by CodeRabbit
