* media: fix pdf build with Spinx 1.6Mauro Carvalho Chehab2017-08-261-8/+15
| | | | | | | | | | | | | | | | | | | | | | Sphinx 1.6 generates some LaTeX code before each table, starting its own environment before calling tabulary, apparently to improve table layout. The problem is that such environment is incompatible with adjustbox. While, in thesis, it should be possible to override it or to redefine tabulary, I was unable to produce such patch. Also, that would likely break on some future Sphinx version. So, instead, let's just change the font size on bigger tables, in order for them to fit into the page size. That is not as good as adjustbox, and require some manual work, but it should be less sensitive to Sphinx changes. While here, adjust a few other tables whose text is exceeding the cell boundaries.

* [media] v4l: doc: Remove row numbers from tablesLaurent Pinchart2016-09-221-466/+264
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Shorten the tables by removing row numbers in comments, allowing for later insertion of rows with minimal diffs. All changes have been generated by the following script. import io import re import sys def process_table(fname, data): if fname.endswith('hist-v4l2.rst'): data = re.sub(u'\n{1,2}\t( ?) -( ?) ?', u'\n\t\\1 -\\2', data, flags = re.MULTILINE) data = re.sub(u'\n(\t| )- \.\. row [0-9]+\n\t ?-( ?) ?', u'\\1* -\\2', data, flags = re.MULTILINE) else: data = re.sub(u'\n{1,2} -( ?) ?', u'\n -\\1', data, flags = re.MULTILINE) data = re.sub(u'(\n?)(\n\n - \.\. row 1\n)', u'\n\\2', data, flags = re.MULTILINE) data = re.sub(u'\n - \.\. row [0-9]+\n -( ?) ?', u' * -\\1', data, flags = re.MULTILINE) data = re.sub(u'\n - \.\. row [0-9]+\n \.\.

* [media] dev-sliced-vbi.rst: fix reference for v4l2_mpeg_vbi_ITV0Mauro Carvalho Chehab2016-09-091-2/+4
| | | | | | | | | | The struct v4l2_mpeg_vbi_ITV0 is identical to struct v4l2_mpeg_vbi_itv0, except by its size, and it is documented at the same place at the book. Fix cross reference for it. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
* [media] docs-rst: simplify c:type: cross referencesMauro Carvalho Chehab2016-09-091-3/+3
| | | | | | | | | | | Instead of using c:type:`struct foo <foo>`, use: struct c:type:`foo` This patch was generated via this shell script: for i in `find Documentation/media -type f`; do perl -ne 'if (m/\:c\:type\:\`struct\s+(\S+)\s*\<(\S+)\>\`/) { $s=$1; $r=$2; if ($s eq $r) { s/\:c\:type\:\`struct\s+(\S+)\s*\<(\S+)\>\`/struct :c:type:`$2`/; s/struct\s+struct/struct/; s/(struct\s+\:c\:type\:\`\S+\`)\s+structure/$1/; }} print $_' <$i >a && mv a $i; done Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
* [media] docs-rst: convert uAPI structs to C domainMauro Carvalho Chehab2016-09-091-18/+18
| | | | | | | | | | | | | | | | instead of declaring the uAPI structs using usual refs, e. g.: .. _foo-struct: Use the C domain way: .. c:type:: foo_struct This way, the kAPI documentation can use cross-references to point to the uAPI symbols. That solves about ~100 undefined warnings like: WARNING: c:type reference target not found: foo_struct Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

* [media] dev-sliced-vbi.rst: use a footnote for VBI imagesMauro Carvalho Chehab2016-08-221-2/+4
| | | | | | | | Just like on dvb-raw-vbi.rst, the LaTeX output doesn't work well with cell spans. Also, this is actually a note, so, move it to a footnote. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
* [media] docs-rst: add tabularcolumns to all tablesMauro Carvalho Chehab2016-08-221-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | LaTeX doesn't handle too well auto-width on tables, and ReST markup requires an special tag to give it the needed hints. As we're using A4 paper, we have 17cm of useful spaces. As most media tables have widths, let's use it to generate the needed via the following perl script: my ($line_size, $table_header, $has_cols) = (17.5, 0, 0); my $out; my $header = ""; my @widths = (); sub round { $_[0] > 0 ? int($_[0] + .5) : -int(-$_[0] + .5) } while (<>) { if (!$table_header) { $has_cols = 1 if (m/..\s+tabularcolumns::/); if (m/..\s+flat-table::/) { $table_header = 1; $header = $_; next; } $out .= $_; next; } $header .= $_; @widths = split(/ /, $1) if (m/:widths:\s+(.*)/); if (m/^\n$/) { if (!$has_cols && @widths) { my ($tot, $t, $i) = (0, 0, 0); foreach my $v(@widths) { $tot += $v; }; $out .= ".. tabularcolumns:: |"; for ($i = 0; $i < scalar @widths - 1; $i++) { my $v = $widths[$i]; my $w = round(10 * ($v * $line_size) / $tot) / 10; $out .= sprintf "p{%.1fcm}|", $w; $t += $w; } my $w = $line_size - $t; $out .= sprintf "p{%.1fcm}|\n\n", $w; } $out .= $header; $table_header = 0; $has_cols = 0; $header = ""; @widths = (); } } print $out; Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
* Revert "[media] docs-rst: escape [] characters"Mauro Carvalho Chehab2016-07-131-29/+29
| | | | | | | | | | This patch touches on places where it shouldn't: image files and code examples. Also, it doesn't fix all array occurrences. So, let's revert it. This reverts commit ffbab694ede33c294e5864a5e0bf4d1474446a71.

* [media] doc-rst: use the right markup for footnotesMauro Carvalho Chehab2016-07-121-2/+2

* doc_rst: rename the media Sphinx suff to Documentation/mediaMauro Carvalho Chehab2016-07-081-0/+822
