yodlverbinsert - Generate verb-sections from parts of a file

yodlverbinsert [OPTIONS] [marker] file

Verbinsert is a simple C++ support program that is used for generating verb()-sections in Yodl files using sections of existing files. The files from which sections are included are usually C or Cpp source files, accepting either // or /*-style comment. See the EXAMPLES section for illustrations.

Verbinsert offers the possibility to indent both the initial verb-statement and the inserted file contents. Furthermore, an additional empty line may be inserted before the first line that is actually inserted.

Blank lines at the beginning and end of files are ignored.

The argument marker must start in file’s first column en must either start as a standard C or C++ comment: // or /* must be used. Following that, the remainder of the argument is used as a label, e.g., //label, /*label*/. Except for the first two characters and their locations, and the last two characters of a C-style marker, no special restrictions are imposed upon the label-names. A labeled section ends at the next //= (for labels starting with //) or at the next /**/ (for labels starting with /*). Like the markers, the end-markers must also start in the first columns of lines.
Alternatively, pairs of //+label, or /*+label*/ can be used. For such markers, copying starts at the first line following the first occurrence of the label, and ends when the label is encountered again. When these markers are used any additionally encountered marker-line is simply ignored, and not written to the output stream. This allows labeled sections to be nested.
The argument file must be an existing file.

Verbinsert writes its selected section to its standard output stream.

When files contain identical marker sections then the contents of each of these marker sections is included in the generated verb-section. This allows the inclusion of non-consecutive lines of source files in a verb section.

The default values of options are listed with each of the options between square brackets. The defaults were chosen so that yodlverbinsert performs the behavior of an earlier version of this program, which was not distributed with Yodl.

Process all lines of file (except initial and trailing blank lines). The argument marker must not be specified.
Same as the -a option, but ignoring all lines that can be considered yodlverbinsert (end) marker-lines.
Keep the newlines after
 and before 
. These newlines result in extra empty lines before the first and after the last source code lines. Starting with version 4.02.00 these lines are removed by default.
Immediately following the indentation: lines are prefixed by numbers, occupying 2 columns, followed by a colon and a blank.
Do not write a newline immediately following verb-statement’s open-parenthesis. By default it is written, causing an additional line to be inserted before the first line that’s actually inserted from a file.
-s nSpaces [0]
start each line that is written into the verb-section with nSpaces additional blanks.
-S nSpaces [8]
prefix the verb of the verb-section by nSpaces additional blanks.
-t nTabs [0]
start each line that is written into the verb-section with nTabs additional tab characters. If both -s and -t are specified, the tabs are inserted first.
-T nTabs [0]
prefix the verb of the verb-section by nTabs additional tab characters. If both -S and -T are specified, the tabs are inserted first.

Assume the file demo contains the following text:

preceding text
one 1
trailing text

Then the following commands write the shown output to the program’s standard output:

yodlverbinsert //one demo
one 1
yodlverbinsert -N //one demo
        verb(one 1
yodlverbinsert -n -s4 ’/*two*/’ demo
        1: two
yodlverbinsert -n //+nest’ demo
 1: one 1
 5:     two
