start working on themes #479

bilelmoussaoui · 2017-05-13T14:16:50Z

Should fix #299 #240 once it's ready
This shouldn't be merged yet, more commits are coming this evening!

… PREFIX/ArticleView instead of grsource

src/ArticleTheme.vala

+
+    public FeedReader.ArticleTheme() {
+      // Local themes
+      string theme_dir = GLib.Environment.get_home_dir() + "/.feedreader/themes/";


I'm pretty sure you can't use this path with flatpaks. Also there is already $HOME/.local/feedreader.
You can access that via GLib.Environment.get_user_data_dir() + "/feedreader/"

I will fix that :)

@jangernert Everything should work fine, except a small issue that i couldn't figure out (little tired :/)
The installed themes are correctly detected on both locations global and local one, the fallback theme (saved on gresource works fine too), but the length of the static variable themes on ArticleTheme is always empty (i've added some printing on my local machine and the themes are correctly detected.. but not added to the static Variable)
My Vala skills aren't that good as yours, can you take a look?
Thanks!
Edit: already fixed it on my local machine, i will push that to themes branch with other fixes :)

The ability for users to load third-party themes looks pretty cool!

I took a look through the pull request and thought you might be interested in some feedback. Let me know if any of this is unhelpful.

+                  }
+                }
+              }catch(Error err){
+                corrupted_theme = true;


It would be good to log the error here for debugging purposes.

brendanlong · 2017-05-22T21:22:19Z

src/ArticleTheme.vala

+        while ((name = theme_dir.read_name()) != null){
+          if (name == "theme.json"){
+              corrupted_theme = false;
+              string path = Path.build_filename(theme_path, name);


It looks like we're reading through the directory but only doing something with one file. Could we replace this while loop with:

// etc. string author = ""; try { string path = Path.build_filename(theme_path, "theme.json"); Json.Parser parser = new Json.Parser(); // etc.

The code here is still not complete, i would like to check if there's an article.html & style.css file too. Otherwise the theme will be correct. But yeah it's better to use this 👍

src/ArticleTheme.vala

+          }
+        }
+      }catch(GLib.FileError err){
+


Logging something here would be nice too.

brendanlong · 2017-05-22T21:24:11Z

src/ArticleTheme.vala

+using Gee;
+
+public class  FeedReader.ArticleTheme {
+    private static ArrayList<HashMap<string, string>> ? themes = null;


Consider making the ThemeInfo into a struct:

public struct ThemeInfo { string name; string author; bool is_corrupted; // etc. } private static ArrayList<ThemeInfo>? themes = null; // etc.

Since we know the contents of the map, using a struct is more efficient and easier to work with.

You might also consider making this a map from theme name to theme info so we can more easily lookup themes:

private static HashMap<string, ThemeInfo>? = null; public static HashMap<string, ThemeInfo> getThemes() { ... } public static ThemeInfo? getTheme(string name) { var themes = getThemes(); if (!themes.has(name)) return null; return themes.get(name); } public static bool exists(string name) { return getTheme(name) != null; }

brendanlong · 2017-05-22T21:25:23Z

src/ArticleTheme.vala

+            string path = Path.build_filename(location, name);
+            if(FileUtils.test(path, FileTest.IS_DIR)){
+              var themeInfo = getThemeInfo(path);
+              if (themeInfo.has_key("corrupted") == false){


Since this is the only thing we use "corrupted" for, consider just returning null when the theme is corrupt.

Yeah much better!

src/ArticleTheme.vala

+            }
+          }
+      } catch (GLib.FileError err){
+


One more case where logging would be nice (or just don't catch the exception).

brendanlong · 2017-05-22T21:27:11Z

src/UtilsUI.vala

+    string css = "";
+    try
+    {
+        if (ArticleTheme.isExists(theme) == false) {


It would be simpler to do if (!ArtistTheme.isExists(theme))

Javascript habits :p

brendanlong · 2017-05-22T21:27:29Z

src/ArticleTheme.vala

+      }
+    }
+
+    public static bool isExists(string theme_location){


I would prefer if this was named exists()

brendanlong · 2017-05-22T21:29:33Z

src/UtilsUI.vala

+    string css_id = "$CSS";
+    int css_pos = article.str.index_of(css_id);
+    article.erase(css_pos, css_id.length);
+    article.insert(css_pos, css);


Would string.replace() work here?

It was used before by @jangernert, i will see what can i do. But i was going to remove including the CSS file here as it's not needed. it's even better to just load the html file, this way third-party themes could contain images, fonts that we shouldn't load by ourselves (vala code)

brendanlong · 2017-05-22T21:31:37Z

data/ArticleView/default/article.html

+                    <div id="title" target="_blank" style="font-size:$LARGESIZEpt;"><a href="$URL">$TITLE</a></div>
+                    <div id="author" style="font-size:$SMALLSIZEpt;">
+                         $AUTHOR
+                    </div>


Would it be make sense to use more semantic tags like <h2> instead of <div>?

The theme isn't ready, it's just an example of how things works 👍
Once the Vala code is ready, i will work on two/three themes that will replace the default ones

Oh cool, that makes sense :)

bilelmoussaoui · 2017-05-24T21:56:50Z

@brendanlong Thanks for the review again! I've pushed few modifications on my latest commit :)

brendanlong · 2017-05-25T04:37:50Z

src/ArticleTheme.vala

 public class  FeedReader.ArticleTheme {
-    private static ArrayList<HashMap<string, string>> ? themes = null;
+    private static HashMap<string, ThemeInfo?> ? themes = null;


Why is the second type argument ThemeInfo?? Are there cases where we would want them theme to null?

Not at all, it's just valac complained about not using themeInfo?

bilelmoussaoui · 2017-05-25T21:16:07Z

@jangernert Can you see if everything is alright for you? 👍

jangernert · 2017-10-23T14:27:58Z

Just wanted to mention the cmake files ^^
As default we should imo straight up port the current default theme and just strip out all the color variants

bilelmoussaoui · 2017-10-23T16:30:40Z

@jangernert I will do that :)

jangernert · 2017-10-23T18:38:38Z

Code seems fine and worked flawlessly for me. The only thing missing is to have the 2 themes on the same quality level as the current themes. Otherwise it will be a downgrade from a user point of view.

bilelmoussaoui · 2017-10-23T18:47:04Z

Yeah, lt's what i will work on those days :)
