h2paspp(1)

💖 h2paspp 💖

okay so bestie, welcome to h2paspp(1) — the Free Pascal h2pas preprocessor program. yes it's a whole vibe, and yes you're gonna understand it. no cap. 🦋

✨ SYNOPSIS ✨

h2paspp [-doih] file1 ... filen

🌸 DESCRIPTION 🌸

so here's the tea: h2paspp reads one or more C header files and preprocesses them, writing the result to files with the same name as the originals as it goes along. it's giving "glow up your headers". 💅

now, it does not accept all preprocesser tokens of C — she's selective, she has standards — but she does take care of the following preprocessor directives:

• #define symbol — defines the new symbol symbol. note that macros are not supported. periodt, no macro energy here. 🙈
• #if symbol — the text following this directive is included if symbol is defined.
• #ifdef symbol — the text following this directive is included if symbol is defined.
• #ifndef symbol — the text following this directive is included if symbol is not defined.
• #include filename — include directives are removed, unless the -I option was given, in which case the include file is included and written to the output file. lowkey iconic behaviour.
• #undef symbol — the symbol symbol is undefined.

🎀 USAGE 🎀

h2paspp accepts one or more filenames and preprocesses them. it will read the input, and write output to a file with the same name unless the -o option is given, in which case the file is written to the specified file. 💖

⚠️ note that only one output filename can be given. one. single. file. don't be greedy bestie.

🌈 OPTIONS 🌈

h2paspp has a small number of options to control its behaviour — tiny but mighty, honestly:

• -dsymbol — define the symbol symbol before processing is started. get her ready beforehand ✨
• -h — emit a small helptext. it's literally just a lil help, and we love that for us 🫶
• -ooutfile — if this option is given, the output will be written to a file named outfile. note that only one output file can be given. (yes, we're saying it twice. it's important. iykyk.) 🔥

and that's the whole page, bestie 💜 this was Free Pascal, dated 12 November 2004 — yeah she's vintage, she's a classic, main character energy since 2004, and she still slays. go preprocess something. mwah 💋🌸
