+#+title: iA writer clone within doom-emacs
+#+description:
+#+keywords: blog static
+#+author: Yann Esposito
+#+email: yann@esposito.host
+#+date: [2021-10-24 Sun]
+#+lang: en
+#+options: auto-id:t
+#+startup: showeverything
+
+So I played with tweaking my emacs configuration again.
+I think I made something worth to be shared.
+I wanted to have the same effect than in iA writer within emacs.
+And I just reached this.
+
+So the effect I am looking to achieve can be seen in this gif.
+
+TODO
+
+So mainly it highlight the current sentence (in black) while the rest of
+the text is gray.
+The main issue with the =hl-sentence= package alone is that it set a specific
+face to the current sentence, but does not affect the other text in the buffer.
+In fact to make it work, you need to make the default color grey, and only
+set black for the highlighted text.
+
+But nice, I have recently created a personal theme close to that.
+I created a new one.
+Everything is mostly "gray" except the font ~hl-sentence~ which is black.
+
+And that's it.
+So to make it all work I need.
+
+- a Gray theme;
+- the package ~hl-sentence~,
+- The ~writeroom~ package.
+
+So how to achieve that yourself?
+Here is how I do it.
+
+** The zen-writer theme
+:PROPERTIES:
+:CUSTOM_ID: the-zen-writer-theme
+:END:
+
+
+Download [[./doom-zen-writer-theme.el][Doom Zen-Writer theme]].
+This depend on doom-themes and here is the code of the theme.
+Just put it in you =~/.doom.d/themes= directory
+** add this is your ~packages.el~
+:PROPERTIES:
+:CUSTOM_ID: add-this-is-your--packages-el-
+:END:
+
+#+begin_src elisp
+(package! hl-sentence
+  :pin "86ae38d3103bd20da5485cbdd59dfbd396c45ee4")
+#+end_src
+** Helpers
+:PROPERTIES:
+:CUSTOM_ID: helpers
+:END:
+
+You probably want to be able to put you out of this writing mode.
+Here is a [[file:zen-writer.el][zen-writer.el]] file that contain my keymaps and useful functions.
+
+Put it in you =~/.doom.d/= directory and in you =config.el=
+put
+
+#+begin_src elisp
+(load! "~/.doom.d/zen-writer.el")
+#+end_src
+
+And with this you should pass to zen mode with ~SPC y z z~.
+
+I hope you find this useful.
