Please my friends, help.

Please my friend, help! Give us the HTML document!

liZe · 2017-05-27T08:21:22Z

Probably related to #417.

PauloTeixeiraJunior · 2017-05-30T12:26:31Z

code_html.txt
Code html used to conversion of html to pdf.

liZe · 2017-05-30T13:16:13Z

I can't reproduce the problem. Could you please help me?

Which font do you use (you can find it in the PDF metadata)?
Which versions of Cairo and Pango do you have (I think that you have CairoSVG 1.0.22, not Cairo 1.0.22)?

PauloTeixeiraJunior · 2017-05-30T13:29:02Z

I am using libpango1.0-0 and CairoSVG 1.0.22.
I am using too cairocffi==0.7.1.

So, the font used inside html to conversion from pdf is "Trebuchet MS", Arial, Helvetica, sans-serif;

Thank you for your attention.

PauloTeixeiraJunior · 2017-05-30T14:46:21Z

I roolback a version of the weasyprint to 0.23, and the error ocurred doesn't work.
Probably is a version next to 0.23.

liZe · 2017-05-30T15:25:32Z

@PauloTeixeiraJunior Sorry, but that's not exactly what I wanted 😢. I'd like to have:

the exact version of pango (the result of pango-view --version in a console),
the version of cairo, not cairosvg (the result of cairo-trace --version in a console),
the font embedded in the PDF, not the font-family rule in the HTML (in Evince for example, you can have it by clicking on "Properties" in the burger menu, "Fonts" tab).

PauloTeixeiraJunior · 2017-05-30T15:38:22Z

Sorry @liZe . Now take the version correctly.

pango-view (pango) 1.36.3
The cairo-trace --version returns that doesn't installed. I have only cairoSVG and cairocffi

But, i have tried some versions of weasyprint, and i find out that after version 0.30 this error happens.
In version 0.30 this error does happens.

PauloTeixeiraJunior · 2017-05-31T14:57:56Z

Do you forgot me? ;(

liZe · 2017-05-31T15:14:40Z

Do you forgot me? ;(

No, I just don't spend my time fixing WeasyPrint's bugs.

I really need the font included in your PDF. If you're too lazy to find the font, change the text in your HTML file to avoid the bug and attach the generated PDF in the issue comments.
I'd like to have the version of Cairo you're using. It's installed by your Linux distribution, find the version of the "cairo" or "libcairo" package (the name depends on the distribution).

If I can't reproduce the bug, I can't help you. To reproduce the bug, I need these informations.

PauloTeixeiraJunior · 2017-05-31T16:34:04Z

Sorry @liZe , I realy don't know find out this informations.
I can the informations necessaries:

Fonts used in PDF generated:
- NimbusSanL-Regu and NimbusSanL-Bold
Type 1 / Codification: WinAnsi / Embedded subassembly
My version of the Cairo is 1.13.1

Again, sorry, sorry.
Maybe with this informations you can reproduce the error.

Thank you for all.

PauloTeixeiraJunior · 2017-06-01T17:52:22Z

@liZe Were you able to reproduce the error?

liZe · 2017-06-01T20:14:21Z

Please stop that. Asking me to help you again and again is not a solution, it just gives me a really good reason to ignore you.

My version of the Cairo is 1.13.1

Really? According to this version number, you're using a development version of an unstable branch of Cairo. It's not even tagged on the Cairo repository.

Please attach a PDF, I'll find the information myself.

Were you able to reproduce the error?

And no, I can't reproduce. Here is what I get:

test.pdf

There's no comma in your HTML sample, but there's one in your error message. You didn't provide the HTML sample you have a problem with.

Please try to be serious and give me good information, or I'll just close this issue (by the way, it's probably a duplicate of #417).

gsvimieiro · 2017-06-02T19:09:20Z

Hi liZe

I have the same problem as our friend Paulo, and found that in version 0.30 there is no such problem, but I can not use this version because I use document printing in two columns and version 0.34 solved this question.

Attachment my html
my_html.txt

Related to #472.

liZe · 2017-06-03T13:51:11Z

@gsvimieiro Thanks for this example, it's been fixed in 8109499 (first time I've seen three soft hyphens at the beginning of a line 😉).

@PauloTeixeiraJunior Now that #417 and @gsvimieiro's bug are fixed, could you tell me if your problem is solved?

gsvimieiro · 2017-06-05T17:50:05Z

Dear liZe

I did not found version v0.37 . Do you have launch this release?

liZe · 2017-06-05T21:12:57Z

I did not found version v0.37 . Do you have launch this release?

No, I'd like you to test the current git version, I'll close this issue and release a new version if it works.

gsvimieiro · 2017-06-08T12:03:07Z

Dear liZe

I updated my version to 0.36 according to the following command:
pip install weasyprint==0.36

However the error remains

ERROR 2017-06-08 08:49:47,454 creator 6783 140037945554688 Got u'o, ' between two lines. Expected nothing or a preserved line break

liZe · 2017-06-08T12:11:25Z

I'd like you to test the current git version

Version 0.36 is not the current git version. You can install it with:
pip install git+https://github.com/Kozea/WeasyPrint.git.

gsvimieiro · 2017-06-08T12:19:29Z

OK liZe
Installed according to your instruction but the error remains:

gsvimieiro · 2017-06-08T12:35:13Z

Dear liZe

I'm Sorry

The problem was browser caching. I updated my environment again and now it did not give more error. Thank you very much

liZe · 2017-06-08T12:37:10Z
