All of these are optional and independently controllable. Provides a 'warn()' method so you can generate warning messages that report physical line number, even if the logical line in question spans multiple physical lines. Also provides 'unreadline()' for implementing line-at-a-time lookahead. Constructor is called as: TextFile (filename=None, file=None, **options) It bombs (RuntimeError) if both 'filename' and 'file' are None; 'filename' should be a string, and 'file' a file object (or something that provides 'readline()' and 'close()' methods). It is recommended that you supply at least 'filename', so that TextFile can include it in warning messages. If 'file' is not supplied, TextFile creates its own using the 'open()' builtin. The options are all boolean, and affect the value returned by 'readline()': strip_comments [default: true] strip from "#" to end-of-line, as well as any whitespace leading up to the "#" -- unless it is escaped by a backslash lstrip_ws [default: false] strip leading whitespace from each line before returning it rstrip_ws [default: true] strip trailing whitespace (including line terminator!) from each line before returning it skip_blanks [default: true} skip lines that are empty *after* stripping comments and whitespace. (If both lstrip_ws and rstrip_ws are false, then some lines may consist of solely whitespace: these will *not* be skipped, even if 'skip_blanks' is true.) join_lines [default: false] if a backslash is the last non-newline character on a line after stripping comments and whitespace, join the following line to it to form one "logical line"; if N consecutive lines end with a backslash, then N+1 physical lines will be joined to form one logical line. collapse_join [default: false] strip leading whitespace from lines that are joined to their predecessor; only matters if (join_lines and not lstrip_ws) Note that since 'rstrip_ws' can strip the trailing newline, the semantics of 'readline()' must differ from those of the builtin file object's 'readline()' method! In particular, 'readline()' returns None for end-of-file: an empty string might just be a blank line (or an all-whitespace line), if 'rstrip_ws' is true but 'skip_blanks' is not.t strip_commentsi t skip_blankst lstrip_wsi t rstrip_wst join_linest collapse_joinc K s | d j o | d j o t d ‚ n xV | i i ƒ D]E } | i | ƒ o t | | | | ƒ q7 t | | | i | ƒ q7 Wx8 | i ƒ D]* } | i i | ƒ p t d | ‚ q q W| d j o | i | ƒ n | | _ | | _ d | _ g | _ d S( sü Construct a new TextFile object.

If the current logical line in the file spans multiple physical lines, the warning refers to the whole range, eg. "lines 3-5". If 'line' supplied, it overrides the current line number; it may be a list or tuple to indicate a range of physical lines, or an integer for a single physical line.s warning: s N( t syst stderrt writeR R' R$ R ( R R$ R ( ( R t warn— s c C s | i o | i d } | i d =| Sn d } xÏ| i i ƒ } | d j o d } n | i oµ | o® t i | d ƒ } | d j o q| d j p | | d d j oP | d d j o d p d } | d | !| } t i | ƒ d j o q2 qqt i | d d ƒ } n | i oŸ | o˜ | d j o | i d ƒ | Sn | i o t i | ƒ } n | | } t | i ƒ t j o | i d d | i d <q| i | i d g | _ nT | d j o d Sn t | i ƒ t j o | i d d | _ n | i d | _ | i o | i o t i | ƒ } n; | i o t i | ƒ } n | i o t i | ƒ } n | d j p | d j o | i o q2 n | i oO | d d j o | d } q2 n | d d j o | d d !d } q2 qøn | Sq2 Wd S( sU Read and return a single logical line from the current file (or from an internal buffer if lines have previously been "unread" with 'unreadline()'). If the 'join_lines' option is true, this may involve reading multiple physical lines concatenated into a single string. Updates the current line number, so calling 'warn()' after 'readline()' emits a warning about the physical line(s) just read. Returns None on end-of-file, since the empty string can occur if 'rstrip_ws' is true but 'strip_blanks' is not.iÿÿÿÿR i t #i s \s s \#s2 continuation line immediately precedes end-of-fileiþÿÿÿs \ N( R R R t buildup_lineR t readlineR R R% t findt post eolt stript replaceR R- R t lstripR R R R R t rstripR ( R R/ R2 R3 R ( ( R R0 ¢ sh " $ c C s@ g } x3 | i ƒ } | d j o | Sn | i | ƒ q Wd S( sW Read and return the list of all logical lines remaining in the current file.i N( t linesR R0 R R R ( R R8 R ( ( R t readlines s c C s | i i | ƒ d S( s· Push 'line' (a string) onto an internal buffer that will be checked by future 'readline()' calls.
