I have markdown source and want to generate PDF using Pandoc.
I want to remove ALL sub sections below a specified level in the generated document. E.g. filter them from the source markdown.
Would this be possible with Lua or would it be better to do prefiltering using some other tools?
Got a suggestion from the Lua Google Groups forum which works for me:
local keep_deleting = false
function Block (b)
if b.t == 'Header' and b.level >= 3 then
keep_deleting = true
return {}
elseif b.t == 'Header' then
keep_deleting = false
elseif keep_deleting then
return {}
end
end
import pyPdf
f= open('jayabal_appt.pdf','rb')
pdfl = pyPdf.PdfFileReader(f)
output = pyPdf.PdfFileWriter()
content=""
for i in range(0,1):
content += pdfl.getPage(i).extractText() + "\n"
outpu = open('b.txt','wb')
outpu.write(content)
f.close()
outpu.close()
This is not writing the content of a pdf to a txt file... what shld i do???
Iterate through every page and call extractText() like so:
content = ""
for i in range(0, num_pages):
content += pdfl.getPage(i).extractText() + "\n"
Once you have the full contents you can easily split the lines via the '\n' separator.
EDIT:
Check after the for-loop, whether the variable contents even contains any text. Not all PDF files contain text information.
i need to scrape a p tag which has h3 tag after it but does not have a closing p tag. It looks like this :
<script ad>asdasdasd</script>
<p>Translation companies are
-----------------------
-----------------------
<h3 class="this_class">mind blown site</h3>
There is no </p> tag so i cannot parse it completely. Now i have two questions :
1) can this be parsed using httpagility xpath ?
2) i have a function to find text between two strings (getbetween). But i have a doubt - If i use "asdasdasd" and " is it always 100% that vb.net will use the script tag which is just above h3 because there are 2-3 same lines - "asdasdasd"
3) Any other method you guys are aware of ?
(had to write in code so html does not mess up)
Regards,
It might be a good idea to post some more "real" html to really help you, at least the tags between the h3 and the p.
Anyway, this should get you the p-Tag from the h3-Tag.
HtmlDocument doc = new HtmlDocument();
doc.Load(... //Load the Html...
//Either of these lines will do
HtmlNode pNode = doc.DocumentNode.SelectSingleNode("//h3[#class='this_class']/preceding-sibling::p");
//HtmlNode pNode = doc.DocumentNode.SelectSingleNode("//h3[contains(text(),'mind blown site')]/preceding-sibling::p");
string pInnerHtml = pNode.NextSibling.InnerHtml; //Has the text "Translation companies are...."
So in general, to get all the nodes from the opening p tag to the start of a tag you don't want, you could do this:
var p = doc.DocumentNode.SelectSingleNode("//p");
var h3 = p.SelectSingleNode("following-sibling::h3[#class='this_class']");
var following = new List<string>();
for (var current = p.NextSibling; current != h3; current = current.NextSibling)
{
following.Add(current.InnerText);
}
var innerText = String.Concat(following);
I've got a strange problem connected with content rendering.
I use following code to grab the content:
lib.otherContent = CONTENT
lib.otherContent {
table = tt_content
select {
pidInList = this
orderBy = sorting
where = colPos=0
languageField = sys_language_uid
}
renderObj = COA
renderObj {
10 = TEXT
10.field = header
10.wrap = <h2>|</h2>
20 = TEXT
20.field = bodytext
20.wrap = <div class="article">|</div>
}
}
and everything works fine, except that I'd like to use also predefined column-content templates other than simple text (Text with image, Images only, Bullet list etc.).
The question is: with what I have to replace renderObj = COA and the rest between the brackets to let the TYPO3 display it properly?
Thanks,
I.
The available cObjects are more or less listed in TSRef, chapter 8.
TypoScript for rendering Text w/image can be found in typo3/sysext/css_styled_content/static/v4.3/setup.txt at line 724, and in the neighborhood you'll find e.g. bullets (below) and image (above), which is referenced in textpic line 731. Variants of this is what you'll write in your renderObj.
You will find more details in the file typo3/sysext/cms/tslib/class.tslib_content.php, where e.g. text w/image is found at or around line 897 and is called IMGTEXT (do a case-sensitive search). See also around line 403 in typo3/sysext/css_styled_content/pi1/class.cssstyledcontent_pi1.php, where the newer css-based rendering takes place.
How do I get an outline view in sublime text editor for Windows?
The minimap is helpful but I miss a traditional outline (a klickable list of all the functions in my code in the order they appear for quick navigation and orientation)
Maybe there is a plugin, addon or similar? It would also be nice if you can shortly name which steps are neccesary to make it work.
There is a duplicate of this question on the sublime text forums.
Hit CTRL+R, or CMD+R for Mac, for the function list. This works in Sublime Text 1.3 or above.
A plugin named Outline is available in package control, try it!
https://packagecontrol.io/packages/Outline
Note: it does not work in multi rows/columns mode.
For multiple rows/columns work use this fork:
https://github.com/vlad-wonderkidstudio/SublimeOutline
I use the fold all action. It will minimize everything to the declaration, I can see all the methods/functions, and then expand the one I'm interested in.
I briefly look at SublimeText 3 api and view.find_by_selector(selector) seems to be able to return a list of regions.
So I guess that a plugin that would display the outline/structure of your file is possible.
A plugin that would display something like this:
Note: the function name display plugin could be used as an inspiration to extract the class/methods names or ClassHierarchy to extract the outline structure
If you want to be able to printout or save the outline the ctr / command + r is not very useful.
One can do a simple find all on the following grep ^[^\n]*function[^{]+{ or some variant of it to suit the language and situation you are working in.
Once you do the find all you can copy and paste the result to a new document and depending on the number of functions should not take long to tidy up.
The answer is far from perfect, particularly for cases when the comments have the word function (or it's equivalent) in them, but I do think it's a helpful answer.
With a very quick edit this is the result I got on what I'm working on now.
