+# LaTeX to Markdown Toolkit
+
+Conversion modulaire de projets LaTeX vers Markdown avec Pandoc.
+
+## 🚀 Usage rapide
+
+```bash
+# Conversion complète (LaTeX + bibliographie)
+node index.mjs --clean
+
+# Seulement nettoyer la bibliographie
+node index.mjs --bib-only
+
+# Seulement convertir LaTeX (utilise une .bib existante)
+node index.mjs --convert-only
+```
+
+## 📁 Structure
+
+```
+latex-to-markdown/
+├── index.mjs              # Script principal
+├── latex-converter.mjs    # Convertisseur LaTeX → Markdown
+├── bib-cleaner.mjs       # Nettoyeur de bibliographie

+│   └── sections/
+└── output/               # Résultats de conversion
+    ├── main.md
+    └── main.bib
+```
+
+## 🔧 Modules
+
+### `index.mjs` - Script principal
+Point d'entrée unifié avec options complètes.
+
+**Options :**
+- `--input=PATH` : Fichier LaTeX source
+- `--output=PATH` : Dossier de sortie  
+- `--clean` : Nettoyer le dossier de sortie
+- `--bib-only` : Seulement nettoyer la bibliographie
+- `--convert-only` : Seulement convertir (skip bibliographie)
+
+### `latex-converter.mjs` - Convertisseur
+Conversion LaTeX vers Markdown avec Pandoc.
+
+**Fonctionnalités :**
+- Support natif des macros LaTeX (`+latex_macros`)
+- Gestion automatique des `\input{}`
+- Citations avec `--citeproc`
+- Extraction des images avec `--extract-media`
+- Support mathématique avec `--mathjax`
+
+### `bib-cleaner.mjs` - Nettoyeur de bibliographie
+Supprime les références externes des fichiers `.bib`.
+
+**Nettoyage :**
+- Supprime les `file = {...}` (chemins locaux)
+- Nettoie les virgules doubles
+- Élimine les lignes vides
+
+## 📊 Exemple de workflow
+
+```bash
+# 1. Placer vos fichiers LaTeX dans input/
+cp mon-projet/* input/
+
+# 2. Conversion complète
+node index.mjs --clean
+
+# 3. Récupérer les résultats dans output/
+ls output/
+# → main.md (Markdown converti)
+# → main.bib (Bibliographie nettoyée)
+```
+
+## ⚙️ Configuration avancée
+
+### Chemins personnalisés
+```bash
+node index.mjs \
+  --input=../paper/main.tex \
+  --output=../results/ \
+  --clean
+```
+
+### Usage programmatique
+```javascript
+import { convertLatexToMarkdown, cleanBibliography } from './index.mjs';
+
+// Conversion LaTeX
+await convertLatexToMarkdown('input.tex', 'output/');
+
+// Nettoyage bibliographie
+await cleanBibliography('refs.bib', 'clean-refs.bib');
+```
+
+## 🛠️ Prérequis
+
+- **Node.js** avec support ESM
+- **Pandoc** (`brew install pandoc`)
+
+## 🎯 Pandoc natif
+
+Le toolkit maximise l'utilisation de Pandoc natif :
+
+- **`+latex_macros`** : Gère `\newcommand`, `\renewcommand`
+- **`--citeproc`** : Traitement automatique des citations
+- **`--bibliography`** : Support de `.bib` files
+- **`--extract-media`** : Images automatiques
+- **`--mathjax`** : Mathématiques avancées
+
+Résultat : **95% Pandoc natif, 5% preprocessing minimal** ! 🚀
+
+---
+
+## 📝 État Actuel du Projet
+
+### ✅ Complété
+- **Architecture modulaire** : `index.mjs` + `latex-converter.mjs` + `bib-cleaner.mjs`
+- **Preprocessing LaTeX** : Gestion des `\input{}` pour assembler le document complet
+- **Nettoyage bibliographie** : Suppression des références externes (`file = {...}`)
+- **Conversion Pandoc** : Format `gfm+tex_math_dollars` pour compatibilité Astro
+- **Citations sans crochets** : Format `@citationkey` au lieu de `[@citationkey]`
+- **Gestion des commandes personnalisées** : `\actionchunk`, `\textsc`, `\gets`, etc.
+- **Extraction d'images** : Support automatique via `--extract-media`
+
+### 🔧 En Cours de Résolution
+- **Erreurs Pandoc sur certaines sections** : 
+  - Section `03_reinforcement_learning.tex` contient des constructions LaTeX problématiques
+  - Erreur à la ligne 2011 : `unexpected }` dans le contexte de citations complexes
+  - Commande `\textsc{PopFront(\( \actionchunk_t \))}` mal interprétée
+
+### 🎯 Prochaines Étapes
+1. **Déboguer section 03** : Identifier et corriger les constructions LaTeX incompatibles
+2. **Test sections individuelles** : Valider chaque section séparément
+3. **Améliorer preprocessing** : Ajouter plus de transformations pour gérer les cas complexes
+4. **Validation finale** : Conversion complète du document
+
+### 🚨 Problèmes Identifiés
+- **Commandes imbriquées** : `\textsc{...(\( math \))}` pose problème à Pandoc
+- **Citations complexes** : Certains patterns de citations avec math inline
+- **Math environments** : Quelques environnements non reconnus correctement
+
+### 🔍 Diagnostic
+Dernière erreur :
+```
+Error at "temp_main.tex" (line 2011, column 234):
+unexpected }
+expecting \end{document}
+~@zhaoLearningFineGrainedBimanual2023 adopts a different strategy whereby...
+\( \actionchunk_t \gets \pi(o_t) \) and chunk consumption 
+\( a_t \gets \textsc{PopFront(\( \actionchunk_t \))} \)
+```
+
+Le problème semble être dans l'imbrication de `\textsc{}` avec des expressions mathématiques à l'intérieur.

+% License, as described in lppl.txt in the base LaTeX distribution.
+% Either version 1 or, at your option, any later version.
+% ========================================================================
+% MODIFICATION HISTORY:
+% Sep 16, 1994
+% version 1.4: Correction for use with \reversemargin
+% Sep 29, 1994:
+% version 1.5: Added the \iftopfloat, \ifbotfloat and \iffloatpage commands
+% Oct 4, 1994:
+% version 1.6: Reset single spacing in headers/footers for use with
+% setspace.sty or doublespace.sty
+% Oct 4, 1994:
+% version 1.7: changed \let\@mkboth\markboth to
+% \def\@mkboth{\protect\markboth} to make it more robust
+% Dec 5, 1994:
+% version 1.8: corrections for amsbook/amsart: define \@chapapp and (more
+% importantly) use the \chapter/sectionmark definitions from ps@headings if
+% they exist (which should be true for all standard classes).
+% May 31, 1995:
+% version 1.9: The proposed \renewcommand{\headrulewidth}{\iffloatpage...
+% construction in the doc did not work properly with the fancyplain style. 
+% June 1, 1995:
+% version 1.91: The definition of \@mkboth wasn't restored on subsequent
+% \pagestyle{fancy}'s.
+% June 1, 1995:
+% version 1.92: The sequence \pagestyle{fancyplain} \pagestyle{plain}
+% \pagestyle{fancy} would erroneously select the plain version.
+% June 1, 1995:
+% version 1.93: \fancypagestyle command added.
+% Dec 11, 1995:
+% version 1.94: suggested by Conrad Hughes <chughes@maths.tcd.ie>
+% CJCH, Dec 11, 1995: added \footruleskip to allow control over footrule
+% position (old hardcoded value of .3\normalbaselineskip is far too high
+% when used with very small footer fonts).
+% Jan 31, 1996:
+% version 1.95: call \@normalsize in the reset code if that is defined,
+% otherwise \normalsize.
+% this is to solve a problem with ucthesis.cls, as this doesn't
+% define \@currsize. Unfortunately for latex209 calling \normalsize doesn't
+% work as this is optimized to do very little, so there \@normalsize should
+% be called. Hopefully this code works for all versions of LaTeX known to
+% mankind.  
+% April 25, 1996:
+% version 1.96: initialize \headwidth to a magic (negative) value to catch
+% most common cases that people change it before calling \pagestyle{fancy}.
+% Note it can't be initialized when reading in this file, because
+% \textwidth could be changed afterwards. This is quite probable.
+% We also switch to \MakeUppercase rather than \uppercase and introduce a
+% \nouppercase command for use in headers. and footers.
+% May 3, 1996:
+% version 1.97: Two changes:
+% 1. Undo the change in version 1.8 (using the pagestyle{headings} defaults
+% for the chapter and section marks. The current version of amsbook and
+% amsart classes don't seem to need them anymore. Moreover the standard
+% latex classes don't use \markboth if twoside isn't selected, and this is
+% confusing as \leftmark doesn't work as expected.
+% 2. include a call to \ps@empty in ps@@fancy. This is to solve a problem
+% in the amsbook and amsart classes, that make global changes to \topskip,
+% which are reset in \ps@empty. Hopefully this doesn't break other things.
+% May 7, 1996:
+% version 1.98:
+% Added % after the line  \def\nouppercase
+% May 7, 1996:
+% version 1.99: This is the alpha version of fancyhdr 2.0
+% Introduced the new commands \fancyhead, \fancyfoot, and \fancyhf.
+% Changed \headrulewidth, \footrulewidth, \footruleskip to
+% macros rather than length parameters, In this way they can be
+% conditionalized and they don't consume length registers. There is no need
+% to have them as length registers unless you want to do calculations with
+% them, which is unlikely. Note that this may make some uses of them
+% incompatible (i.e. if you have a file that uses \setlength or \xxxx=)
+% May 10, 1996:
+% version 1.99a:
+% Added a few more % signs
+% May 10, 1996:
+% version 1.99b:
+% Changed the syntax of \f@nfor to be resistent to catcode changes of :=
+% Removed the [1] from the defs of \lhead etc. because the parameter is
+% consumed by the \@[xy]lhead etc. macros.
+% June 24, 1997:
+% version 1.99c:
+% corrected \nouppercase to also include the protected form of \MakeUppercase
+% \global added to manipulation of \headwidth.
+% \iffootnote command added.
+% Some comments added about \@fancyhead and \@fancyfoot.
+% Aug 24, 1998
+% version 1.99d
+% Changed the default \ps@empty to \ps@@empty in order to allow
+% \fancypagestyle{empty} redefinition.
+% Oct 11, 2000
+% version 2.0
+% Added LPPL license clause.
+%
+% A check for \headheight is added. An errormessage is given (once) if the
+% header is too large. Empty headers don't generate the error even if
+% \headheight is very small or even 0pt. 
+% Warning added for the use of 'E' option when twoside option is not used.
+% In this case the 'E' fields will never be used.
+%
+% Mar 10, 2002
+% version 2.1beta
+% New command: \fancyhfoffset[place]{length}
+% defines offsets to be applied to the header/footer to let it stick into
+% the margins (if length > 0).
+% place is like in fancyhead, except that only E,O,L,R can be used.
+% This replaces the old calculation based on \headwidth and the marginpar
+% area.
+% \headwidth will be dynamically calculated in the headers/footers when
+% this is used.
+%
+% Mar 26, 2002
+% version 2.1beta2
+% \fancyhfoffset now also takes h,f as possible letters in the argument to
+% allow the header and footer widths to be different.
+% New commands \fancyheadoffset and \fancyfootoffset added comparable to
+% \fancyhead and \fancyfoot.
+% Errormessages and warnings have been made more informative.
+%
+% Dec 9, 2002
+% version 2.1
+% The defaults for \footrulewidth, \plainheadrulewidth and
+% \plainfootrulewidth are changed from \z@skip to 0pt. In this way when
+% someone inadvertantly uses \setlength to change any of these, the value
+% of \z@skip will not be changed, rather an errormessage will be given.
+
+% March 3, 2004
+% Release of version 3.0
+
+% Oct 7, 2004
+% version 3.1
+% Added '\endlinechar=13' to \fancy@reset to prevent problems with
+% includegraphics in header when verbatiminput is active.
+
+% March 22, 2005
+% version 3.2
+% reset \everypar (the real one) in \fancy@reset because spanish.ldf does
+% strange things with \everypar between << and >>.
