A crash report was automatically generated with the following information:
  - A verbatim copy of the crash traceback.
  - A copy of your input history during this session.
  - Data on your current ipython configuration.

It was left in the file named:
        '/home/local/ANT/dylone/.ipython/Crash_report_ipython.txt'
If you can email this file to the developers, the information in it will help
them in understanding and correcting the problem.

You can mail it to: The IPython Development Team at [email protected]
with the subject 'ipython Crash Report'.

If you want to do it now, the following command will work (under Unix):
mail -s 'ipython Crash Report' [email protected] < /home/local/ANT/dylone/.ipython/Crash_report_ipython.txt

In your email, please also include information about:
- The operating system under which the crash happened: Linux, macOS, Windows,
  other, and which exact version (for example: Ubuntu 16.04.3, macOS 10.13.2,
  Windows 10 Pro), and whether it is 32-bit or 64-bit;
- How ipython was installed: using pip or conda, from GitHub, as part of
  a Docker container, or other, providing more detail if possible;
- How to reproduce the crash: what exact sequence of instructions can one
  input to get the same crash? Ideally, find a minimal yet complete sequence
  of instructions that yields the crash.

Alors
ipython>=7.0.0 utilise prompt_toolkit>=2.0.0,<2.1.0
ipython<7.0.0 utilise prompt_toolkit>=1.0.15,<2.0.0

Dans prompt_toolkit <2.0.0 invalidation_hash renvoie toujours str ou int , mais dans les dernières versions, il peut également renvoyer tuple .

Pour contourner le problème, j'utilise ceci:

Cependant, je ne suis pas sûr que cela vaille la peine de créer un PR avec cela. Ça n'a pas l'air soigné.

Cela vaudrait-il la peine de créer un fichier de type since_7.py avec un correctif approprié?

Cela pourrait-il être fait? Cela m'empêche d'utiliser Powerline.

Le correctif mentionné ci-dessus fait que Powerline ne plante pas, mais ne le résout pas. Comme dans, l'invite affichée est laide, avec "&" affiché partout où la couleur est censée changer.

Les caractères & semblent être des espaces insécables ( \xa0 ); les désactiver via la configuration du thème les remplace par des espaces normaux. Cependant, les couleurs ne semblent toujours pas changer et tout a un fond transparent et #00005f comme couleur de premier plan.

Je peux confirmer que Powerline est cassé pour les versions actuelles d'iPython (7.4 dans mon cas).
Le correctif suggéré par @Zebradil rend iPython au moins réutilisable (merci!) Mais -
comme déjà mentionné - décore l'invite avec & au lieu de couleurs.

Je rencontre ce problème dans mon IPython 7.3.0. Vous devez arrêter l'extension pour utiliser IPython.

Quand le réparez-vous ~~~

N'hésitez pas à continuer. Commencez avec le patch de @Zebradil et jetez un œil
pourquoi l'invite iPython est réduite à un certain nombre de & s.

Vous aideriez beaucoup de personnes affectées par ce bogue.

Que signifie "décore l'invite avec & au lieu de couleurs". ressembler? J'utilise le patch et il ressemble à ci-dessous:

Il n'y en a pas &.

Merci d'avoir approfondi ce problème!

Il n'y en a pas &.

Dans votre cas, le "&" a été remplacé par "_" - intéressant,
semble dépendre du système que vous utilisez.

Voici à quoi ressemble l'invite sous Kubuntu 18.04:

Les caractères & semblent être des espaces insécables ( \xa0 ); les désactiver via la configuration du thème les remplace par des espaces normaux. Cependant, les couleurs ne semblent toujours pas changer et tout a un fond transparent et #00005f comme couleur de premier plan.

Je pense toujours que le problème concernant les & est un autre problème, qui n'est pas lié aux couleurs.

Dans votre cas, le "&" a été remplacé par "_" - intéressant,
semble dépendre du système que vous utilisez.

Cela ne dépend pas du système mais de la version de
prompt-toolkit: je suis passé de 2.0.7 à 2.0.9
et tous les "&" sont "_" maintenant.

C'est / était une nouvelle fonctionnalité de la 2.0.8:

• Soulignez les espaces insécables au lieu de rendre "&".

@acgtyrant avez-vous 2.0.9 installé?

Pour les couleurs, il semble que quoi que ce soit après le Token.Generic.Prompt soit ignoré: https://github.com/powerline/powerline/blob/5d82d544f3366a214732aeb8f781d50ced38ceef/powerline/renderers/ipython/since_5.py#L121

Autant que je sache, pour chaque groupe de surbrillance, un nouveau type de jeton est créé et le DynamicStyle défini dans renderers / ipython / since_5.py est censé créer le style correspondant. Cependant, il semble que ni get_attrs_for_token ni get_token_to_attributes_dict soient appelés; en regardant https://github.com/prompt-toolkit/python-prompt-toolkit/commit/c32f3783a76e6b72d53acda0b6c4a15ef13bed3b révèle que prompt_toolkit n'utilise plus get_attrs_for_token , mais utilise get_attrs_for_style_str place.

Il semble que j'ai une solution (très hacky) au problème de couleur: enregistrez tous les faits saillants utilisés dans hl , convertissez-les en paires de formats de style prompt_toolkit et ajoutez ces nouvelles paires aux règles de style déjà générées par l'implémentation

    <strong i="7">@property</strong>
    def style_rules(self):

dans le class PowerlinePromptStyle(DynamicStyle): .

Comme vous pouvez le voir, j'ai encore besoin de nettoyer le code, mais cela semble fonctionner.

@ PH111P - Excellent travail, merci d'avoir plongé dans le

Ainsi, les deux nouveaux problèmes (les couleurs manquantes et les "&" / "_") sont causés par le
mise à niveau de prompt-toolkit vers la version 2?

Ainsi, les deux nouveaux problèmes (les couleurs manquantes et les "&" / "_") sont causés par le

Je pense que oui, oui.

Peut-être que le guide "Mise à jour vers prompt_toolkit 2.0" peut vous aider
puisqu'il explique les changements nécessaires:

https://python-prompt-toolkit.readthedocs.io/en/master/pages/upgrading.html#pygments -styles-and-token

Une implémentation du correctif de couleur peut être trouvée ici https://github.com/PH111P/powerline/blob/develop/powerline/renderers/ipython/since_7.py
Le problème avec les nbsp peut être résolu en les désactivant dans les fichiers de configuration (en définissant "use_non_breaking_spaces": false ).

Si j'ai un peu de temps, je pourrais écrire une pull request.

@GHPS J'ai installé 2.0.8-1.

Une implémentation du correctif de couleur peut être trouvée ici

Génial - vous l'avez corrigé. iPython et Powerline sont à nouveau utilisables!
Merci d'avoir pris le temps et de régler le problème ...

Voyez-vous une chance de ressusciter l'indicateur de mode VI
ainsi que? Il manque actuellement ...

J'ajoute le correctif de couleur et la config, mais il y a encore _ dans mon IPython, je ne sais pas pourquoi.

Ah désolé, en effet on ne peut pas vraiment utiliser le fichier de configuration pour cela (le drapeau mentionné ne fonctionne qu'au niveau du thème global; personnellement, j'ai désactivé globalement les nbsp dans la source mais cela ne devrait pas être la voie à suivre); il semble que pour corriger les nbsp, le moteur de rendu ipython doit être changé, en particulier l'ajout de quelque chose comme ce qui suit à class IPythonPygmentsRenderer(IPythonRenderer): devrait résoudre ce problème
(cette fois, j'ai testé cette solution de contournement, encore une fois désolé que l'autre chose n'ait pas vraiment fonctionné; voir aussi https://github.com/PH111P/powerline/blob/develop/powerline/renderers/ipython/since_7.py)

Il semble qu'il n'y ait tout simplement aucun segment avec cette fonctionnalité. Cependant, quelque chose le long de ce qui suit semble fonctionner, n'hésitez pas à le convertir en un segment à part entière (la plupart du code est volé sans vergogne dans l'implémentation ipython réelle: https://github.com/ipython/ipython/blob/4f901de17aff2132365fc3741fc5b4b8a9a98dc6 /IPython/terminal/prompts.py#L16):

        return str(ipython.pt_app.app.vi_state.input_mode)[3:6]
    else:
        return None

EDIT : Bien qu'il semble montrer le mode actuel, il ne semble pas vraiment se mettre à jour: /. Je dois admettre que je n'utilise pas vraiment le mode vi dans ipython, donc je ne peux pas vraiment tester cela.

Le PR semble être resté sans surveillance pendant un certain temps. Est-il prévu de mettre à jour cela?

Autant que je sache, tout (sauf --simple-prompt ) semble fonctionner, donc je ne suis pas tout à fait sûr de ce à quoi vous faites référence, @teracamo. (En effet, le PR n'a pas encore fusionné, mais cela semble être lié à # 2012; également à proprement parler le PR manque encore de tests, mais comme je l'ai dit, il devrait déjà être utilisable)

Oh, je fais simplement référence à s'il y a un plan pour que ce PR soit fusionné, car la version actuelle ne fonctionne pas sur ipython> = 7.0.
Je n'ai pas encore essayé le PR moi-même, donc je ne peux rien dire sur l'option --simple-prompt mais je le ferai s'il n'y a pas de plan de fusion.

@alabamagan comment va https://github.com/powerline/powerline/pull/2048 ?

Jusqu'à ce que les modifications soient publiées, consultez la branche develop pour les obtenir. Cela peut être moins stable que master , mais il vaut mieux ne pas pouvoir utiliser les invites Powerline du tout:

pip install --user 'git+https://github.com/powerline/powerline.git@develop#powerline'

Ensuite, dans votre configuration ipython, changez since_5 en since_7 , comme ceci:

from powerline.bindings.ipython.since_7 import PowerlinePrompts
c.TerminalInteractiveShell.simple_prompt = False
c.TerminalInteractiveShell.prompts_class = PowerlinePrompts

Combien de temps avant leur libération?

Peut-être qu'une nouvelle version est nécessaire.
La dernière version date d'il y a 2 ans.

Merci pour une nouvelle version. Mais j'ai quand même rencontré ce bogue après avoir mis à niveau Powerline vers 2.8-1. Je ne sais pas pourquoi.

Je l'ai ajouté dans la configuration et cela fonctionne maintenant. Je vous remercie!

Merci pour une nouvelle version. Mais j'ai quand même rencontré ce bogue après avoir mis à niveau Powerline vers 2.8-1. Je ne sais pas pourquoi.

Le document n'est pas mis à jour.

En effet, les documents sont assez anciens (la dernière version date d'il y a environ 1,5 ans). Cependant, les builds automatiques ne fonctionnent pas et je n'ai pas les autorisations pour vérifier / modifier quoi que ce soit sur les configurations, désolé.

@ PH111P Veuillez également

Malheureusement, je ne pense pas avoir le droit d'accès de le faire.
En attendant, vous pouvez essayer pip install git+https://github.com/powerline/powerline.git@develop .
