Is there any way to convert file's line ending on saving?

#1

Couldn’t find any suitable plugin on package control.

Have you tried looking in the View menu -> Line Endings -> …?

Thank you for replying, I know I can manually convert line ending, but I have to do this manually for every each single file, I really hope I can do this automatically.
Also I know how to write script to convert all the files together, but that would lead a huge change list on our P4, will affect all the other colleagues, so I hope to do it quietly, single file each time I edited it.

Save this as change_line_endings.py in your User package folder. I generally wouldn’t recommend this, but I hope you know what you’re doing with this.

import sublime_plugin

# Options are: "Windows", "Unix", "CR" (don't use CR)
PREFERRED_LINEENDINGS = "Unix"


class SilentlyChangeLineEndingsListener(sublime_plugin.EventListener):
    def on_pre_save(self, view):
        if view.line_endings() != PREFERRED_LINEENDINGS:
            view.set_line_endings(PREFERRED_LINEENDINGS)

Wow, awesome, write custom plugin, almost forget this :smile:
OK, I’ll go this way, good side is I can check and convert the encoding at the same time, appreciate!
I just wonder such simple task, sublime text doesn’t support and even package control doesnt have a suitable one, or it’s just a dumb task that no one ever need it😆

As I mentioned, I generally wouldn’t recommend it because you either change line endings manually (on demand) or automatically, in which case you’d rather batch-edit many files using a commandline tool like dos2unix (or unix2dos). Other than that, you generally want to respect the original line endings used by a file so you don’t cause a mess in version control software or in other software that reads a file and expects certain line endings (Windows’s notepad.exe can’t handle UNIX line breaks, for example).

Add to the fact that this is a very trivial plugin and it’s not very surprising that a plugin like this does not exist. Or maybe it even does exist, but you didn’t find it (and I didn’t even bother to look).

For encodings, there certainly are more packages, so one of them might provide what you would be looking for.

Just to provide a less aggressive solution. You can also create a keybinding to change the line endings and save. Install Chain of Commands and add this to your keymap:

    {
        "keys": ["alt+s"],  // use "ctrl+s" to overwrite save
        "command": "chain",
        "args": {
            "commands": [
                ["set_line_ending", {"type": "unix"}], // also possible: "unix", "windows", "cr"
                ["save"]
            ]
        },
    },

My situation here is quit tricky, we had our line ending & encoding standard, but we don’t have any tool for restriction of everybody, some of interns were using different line ending & encoding deal some of the source file in chaos, after we realize it, it like a hundred has been messed, it’s not that big deal to let everybody in the team to be aware this, so I rather to change them one by one once I touch the file. It’s just that simple, I am familiar the situation and all the tricky things behind this, very thank you for all the suggestion, I’ll make my custom plugin to do this:)

thanks this actually helped me! a slight improvement to the script: add regexp to configure more finely the files we want to convert:

class SilentlyChangeLineEndingsListener(sublime_plugin.EventListener):
def on_pre_save(self, view):
if re.search(’.ksh|.sh|.cfg|.conf$’, view.file_name()):
if view.line_endings() != PREFERRED_LINEENDINGS:
view.set_line_endings(PREFERRED_LINEENDINGS)

Install the EditorConfig Sublime package, and create an EditorConfig file https://editorconfig.org/
This will allow standardised configurations across multilple editors

For anyone who got here from the Internet wondering how to set the default line endings used by Sublime without using the plugin above:

Preferences > Settings > add: “default_line_ending”: “unix”

Mind the JSON syntax.

// Settings in here override those in "Default/Preferences.sublime-settings",
// and are overridden in turn by syntax-specific settings.
{
        "default_line_ending": "unix",
}
