asciinema2gif's Issues

Eats up all my ram

It just ate up something like 15GBs of ram/swap while trying to convert https://asciinema.org/a/3uftg7cenn3dgga0ji8w1xniu?speed=2 with -s small - anything I can do?

'ReferenceError: Can't find variable: $'

I am following the exact command in the README and am getting the following result. I tried using both my own recordings and the default one on asciinema.org.

asciinema2gif --theme solarized-light -o "${HOME}/Desktop/another.gif" https://asciinema.org/api/asciicasts/8332
ReferenceError: Can't find variable: $

  undefined:2
  :4

The recording is of nothing. I simply started and then stopped the recorder and that was the error I received every time.

I am using OS X Sierra (or macOS or whatever it is called). I have used it in and out of tmux, and tried both bash and zsh. I have tried using node versions 0.10.30, 4.6.0 and 6.4.0. I am happy to try any other recommend debugging techniques if that would be helpful.

I tried to use phantomjs but with no success.

Support for providing file instead of url

Here I get Wrong URL format

asciinema2gif --size small --speed 2 -o "${HOME}/Desktop/another.gif" /Users/thomasreggi/Desktop/example.json 

Why use gifsicle with imagemagick?

Some other gif creation scripts also tend to use gifsicle, which is fine, but why use it when using imagemagick as well? That seems to me like one dependency too many, since imagemagick can also create and optimize gifs just as well.

I usually do just fine with a simple convert command. Is there any strong reason to require gifsicle?

Refactor render.js

it's hard to maintain

Get stuck with error: TypeError: undefined is not an object (evaluating 'el.dispatchEvent')

Repro:

brew install asciinema2gif

$ asciinema2gif -s small -t solarized-dark -o demo2.gif https://asciinema.org/api/asciicasts/dD9UhCIaPw13znirhmGUnNJtd
>> Dimensions: undefinedxundefined
>> Preparing window ...
TypeError: undefined is not an object (evaluating 'el.dispatchEvent')

  undefined:47
  :48
(hangs here forever)

Add option to read data from file

Asciinema supports saving recordings to file now. Not having to upload recordings before conversion would be nice.

"SSL handshake failed" while trying to convert an asciicast to a gif

Hi,

Thanks a lot for your work which seems to work great. Nevertheless, I try to convert an asciicast to a gif following your examples and I face an SSL error. Actually, I run this command:

./asciinema2gif --theme solarized-light -o "${HOME}/Bureau/test.gif" https://asciinema.org/api/asciicasts/81648

and I get the following error codes:

ERROR: Couldn't open https://asciinema.org/api/asciicasts/81648?theme=solarized-light.
ERROR: SSL handshake failed

My asciicast is public. And I get the same error codes while trying to run simply:

./asciinema2gif --size small --speed 2 --theme solarized-light 81648

Any idea why?

I just would like to note I think I have all the dependencies installed and I'm on Ubuntu 14.04 LTS

Many thanks for your help. Don't hesitate to tell me if I post in the wrong place...

It's broken :-(

see #5

asciienema2gif fails due to SSL Error

Just created a cast with asciienema2 and tried to convert it with asciienema2gif and it fails with:

ERROR: Error creating SSL context (error:140A90C4:SSL routines:func(169):reason(196))

Running Debian Testing.

Option args for other asciinema configurables

It would be nice if we could pass option args to asciinema2gif that are supported in the GET request to the https://asciinema.org/api/asciicasts/ resource. e.g. speed, tframe, etc.

This would preclude users from having to figure out the ugly GET request syntax with their desired parameters before running the URL by asciinema2gif. i.e. https://asciinema.org/api/asciicasts/88888?t=4&speed=2

phantomjs binary name

I tried to use the script, and run it, however it could not find the binary: phantomjs2.
This is the error message I am recieving:

./asciinema2gif: line 19: phantomjs2: command not found

I checked in the binary for phantomjs2 and under phantomjs2/bin: I saw the name of the binary was phantomjs.

I changed line 19 to phantomjs and ran the script and it worked afterwards. Is this something that needs to be updated?

i reimplemented the shellscript in typescript

during a coding session i reimplemented the shellscript using typescript if you want to check it out look here https://github.com/jfmherokiller/asciinema2gif i am hopeing to work my way up to that pull request where i can add file to gif support

asciinema2gif always results in Error 404

I just cannot get it to work.

$ asciinema2gif 125790
ERROR: https://asciinema.org/api/asciicasts/125790 returns 404

Thanks.

Gif generation memory leak

Once the gif generation starts it's eating all my available memory very quickly (like 8gb in a few seconds)

Using master and:

[email protected]
imagemagick 6.9.5.10-1

Hassle installing phantomjs on Debian 8

npm install --global phantomjs2 threw me errors on Debian 8, with something to do about the 'node' legacy binary.
This page helped me out. I suggest adding a Debian installation section just to save other people the trouble of figuring out why phantomjs won't install.

mktemp: too few X's in template ‘asciinema2gif’

When running the example from the readme I get this:

$ ./asciinema2gif --theme solarized-light -o "${HOME}/Desktop/another.gif" https://asciinema.org/api/asciicasts/8332
mktemp: too few X's in template ‘asciinema2gif’
: No such file or directory

The same happens with any asciicast numer or url and with different settings.

Add it to homebrew?

then OS X users can use brew install asciinema2gif to install it

Unclear Ubuntu installation docs

Installing asciinema2gif from a MacOS was a breeze. However things are not quite clear with Ubuntu.

Any way to improve it?

Size flag doesn't seem to be working

I'm able to adjust the size by giving asciinema.org the size=big option, shown here: https://asciinema.org/api/asciicasts/5ljjg4iuybn8wpf5rk67m1e9z?size=big

However, when I tried:

asciinema2gif --size big -o output_big.gif https://asciinema.org/api/asciicasts/5ljjg4iuybn8wpf5rk67m1e9z

The size is still small.

Am I missing something here?

Thanks for your help 😄

Parsing ID and URL both fails

Seems like the /api/asciicasts URL is no longer available

$ asciinema2gif https://asciinema.org/api/asciicasts/123683ERROR: https://asciinema.org/api/asciicasts/123683 returns 404
$ asciinema2gif https://asciinema.org/a/123683

Wrong URL format. See https://github.com/tav/asciinema2gif#url-format.

Neither does parsing by ID work

$ asciinema2gif 123683
ERROR: https://asciinema.org/api/asciicasts/123683 returns 404

Output contains part of the webpage, not just the terminal output...

It works well, but I was expecting the output to resemble what is have embedded in README.md as an example. Instead, the resulting gif contains a portion of the webpage.

e.g: http://i.imgur.com/g40TBU0.gifv

Is there an option I'm missing? If not, can this be added?
