The OpenType feature file specification states that due to historical reasons, relative imports should be resolved in this order: 1. If the source font is UFO format, then relative to the UFO's font directory 2. relative to the top-level include file 3. relative to the parent include file We only support 1 (via includeDir) and 2.

Behavior: If includeDir is passed, it will be used to determine the top-level include directory to use for all encountered include statements. If it is not passed, ``os.path.dirname(featurefile)`` will be considered the include directory. rN) make_lexer_lexers_rfeaturefilepathrh)rZ featurefilerhr"r"r#r$s  zIncludingLexer.__init__cCr%r&r"r'r"r"r#r(r)zIncludingLexer.__iter__cCr*r&r+r'r"r"r#r-r.zIncludingLexer.nextc Cs2|jr|jd}z t|\}}}Wnty|jYqw|tjur|dkr|\}}}|tjur:td|tj |rC|}n!|j durL|j } n|j durYtj |j } nt} tj | |}t|jdkrptd|z |j||Wnty} zt||| d} ~ ww|||fS|jst)Nr>zExpected file namezToo many recursive includes)rjr-rHpoprr r rospathisabsrhrkdirnamegetcwdjoinrappendriFileNotFoundErrorr) rZlexerr0r1r2Z fname_typeZ fname_tokenZfname_locationrpZcurpatherrr"r"r#r,s>           $zIncludingLexer.__next__cCsXt|dr |d}}n |d}}t|ddd}|}t|dd}|r'|t||S)NreadFTrzutf-8)encodingname)hasattropenrxgetattrcloser)Z file_or_pathZfileobjclosingr!datar"r"r#ri s     zIncludingLexer.make_lexer_cCs|jd|S)Nrl)rjrb)rrar"r"r#rbsz#IncludingLexer.scan_anonymous_block) rcrdre__doc__r$r(r-r, staticmethodrirbr"r"r"r#rgs'  rgc@seZdZdZddZdS)NonIncludingLexerzBLexer that does not follow `include` statements, emits them as-is.cCst|jdS)Nr)r-rjr'r"r"r#r,szNonIncludingLexer.__next__N)rcrdrerr,r"r"r"r#rs r)ZfontTools.feaLib.errorrrZfontTools.feaLib.locationrrUror ImportErrorZfontTools.miscobjectrrgrr"r"r"r#s   4[
