Export code and output as pdf file
Hello guys! how are you doing?
Ireally need to know how can I export in PDF the code and the output of a program in Pythonista. I’m having this programming class where the professor asked for us to send only the .pdf files containing the solution of the exercises + the code that we wrote. It’s as simple as it sounds and still I’m so mad I didn’t figure it out, sorry..
I searched in quite a lot of topics but couldn’t find anywhere, only that maybe has something to do with Py2PDF on Pythonista.
@cvp, but aren’t we making this unnecessarily difficult? In Apple Shortcuts, there is a Create PDF action, and the Gallery includes a ready-made script for that (select the margins switch to make it look nicer).
When viewing the code in Pythonista, select wrench, Share, Shortcuts and pick this Shortcut - done.
Something fancy could be created to automate this for a large number of files and their outputs, but for the OP issue, probably enough?
@mikael Sorry, which shortcut? If it exists 😂,I agree with you. I often write a little script for the fun and that allows me to postpone my (too) big projects
Edit: bad read of your post, I think there was an Apple standard shortcut, sorry, one more time
Edit2: very good but I wanted to get the syntax highlighting like in editor
@johnsilvabr this little script
- is based on an @omz sample
- needs that you install xhtml2pdf via stash, then pip install xhtml2pdf
- can be added as a tool via wrench menu
- when executed on an edited script, creates a file script_name.pdf with highlighted code
# code needs to install xhtml2pdf in site-packages # via stash/pip install xhtml2pdf import editor import os from pygments import highlight from pygments.lexers import PythonLexer from pygments.formatters import HtmlFormatter from pygments.styles import get_style_by_name from xhtml2pdf import pisa # Syntax-highlight code # from omz code at https://forum.omz-software.com/topic/1950/syntax-highlight-python-code-on-screen-while-running code = editor.get_text() html_formatter = HtmlFormatter(style='colorful') highlighted_code = highlight(code, PythonLexer(), html_formatter) styles = html_formatter.get_style_defs() html = '<html><head><style>%s</style></head><body>%s</body></html>' % (styles, highlighted_code) # html -> pdf path = editor.get_path() file_name = os.path.basename(path) i = file_name.rfind('.') if i>= 0: file_name = file_name[:i] + '.pdf' with open(file_name, 'wb') as fil: pisa.CreatePDF(html,fil)
@mikael I had also thought to an online conversion html to pdf but it needs Internet and you have to share/select Shortcuts/select shortcut instead of tools/select tool
thus one step more 😂
all I deduce is that we have a great application with Pythonista
Edit: could you share the shortcut, I'm interested, thanks
Edit2: and your solution provides lines numbers, I'm giving up, you're the best
Note the professor wants both code AND program output.
(output, i can understand... i have no idea why anyone would ever want to see python code in pdf form)
I imagine also that he might expect some kind of header/format?
@JonB Agree, but passing via html helps for other infos like headers..., isn'it.
@mikael Thanks a lot. I didn't even know this feature of posting to an API in Shortcuts app.
I like it.
I always try to process all in Pythonista but I wait the day when @omz would add the functionality to share/open a file to a specific app without passing via a menu, because Shortcuts can do it...
path = editor.get_path() file_name = os.path.basename(path) i = file_name.rfind('.') if i>= 0: file_name = file_name[:i] + '.pdf' # Can be rewritten as... file_name = os.path.basename(os.path.splitext(editor.get_path())) + '.pdf'
@ccc Thanks. Shame on me, I knew it.... 😢
Edit: also modified in my github
Still to find in the tool the way to get the console output to add it to the pdf...
@cvp, easier to redirect all output to a file?
@mikael Sure but needs to change the code?
This code should return the console content
from objc_util import * def GetConsoleText(): print('called') win = ObjCClass('UIApplication').sharedApplication().keyWindow() main_view = win.rootViewController().view() ret = '' def analyze(v): ret = None for sv in v.subviews(): if 'textview' in str(sv._get_objc_classname()).lower(): if 'OMTextEditorView' not in str(sv.superview()._get_objc_classname()): # not TextView of script return sv.text() ret = analyze(sv) if ret: return ret ret = analyze(main_view) return ret
Thus full code can be found here
@cvp, no need to change the code:
import contextlib, runpy with open('ex1_result.txt', 'w') as f: with contextlib.redirect_stdout(f): runpy.run_module('ex1')
@mikael I didn't know this functionality.
But, that will say that the whole console is redirected, even if your script asks questions...
Anyway, this is a shorter and general solution.
@cvp, agree, case by case either option may be more applicable. I wanted to remind us of both of these capabilities (running a py file and redirecting output), as both might come handy in various contexts.
@mikael "My" solution is not very elegant and I'm not sure it is robust and would stay operational in next versions of Pythonista.
I searched this way for the fun because I I thought that if the console is displayed and is scrollable, it has to be in a TextView...
And during my tests, I discovered the "console 🔽 " button and its pop up menu where you can copy all the console...In the past, I often selected the whole text and copied without knowing this possibility 😢
